    Full Text Available Structural valvular heart disease may be the cause of heart failure or may worsen the clinical status of patients with heart failure. Heart failure may also develop in patients treated with valve surgery. Patients with heart failure with valvular heart disease are at increased risk of events including sudden cardiac death. Before considering intervention (surgical or percutaneous all patients should receive appropriate medical and device therapy taking into account that vasodilators must be used with caution in patients with severe aortic stenosis. Numerous percutaneous and/or hybrid procedures have been introduced in the past few years and they are changing the management of valvular heart disease. In patients with heart failure and valvular heart disease, either primary or functional, the whole process of decision-making should be staged through a comprehensive evaluation of the risk– benefit ratio of different treatment strategies and should be made by a multidisciplinary ‘heart team’ with a particular expertise in valvular heart disease. The heart team should include heart failure cardiologists, cardiac surgeons/structural valve interventionists, imaging specialists, anaesthetists, geriatricians and intensive care specialists. This article will review recent developments and distill practical guidance in the management of this important heart failure co-morbidity.

    This article outlines the diagnosis and management of commonly occurring valvular heart diseases for the primary care provider. Basic understanding of pathologic murmurs is important for appropriate referral. Echocardiography is the gold standard for diagnosis and severity grading. Patients with progressive valvular heart disease should be followed annually by cardiology and imaging should be performed based on the severity of valvular dysfunction. Surgery or intervention is recommended only when symptoms dictate or when changes in left ventricular function occur. Surgery or intervention should be performed after discussion by a heart team, including cardiologists and cardiac surgeons. Published by Elsevier Inc.

    Valvular heart disease presents as mixed spectrum lesion in healthcare settings in the third-world and developing countries. Rheumatic heart disease still forms the bulk of the aetiopathology of valve lesions. Mitral and aortic valve lesions top the list of valvular pathology. A thorough understanding of the pathophysiology of valvular heart disease is essential while planning anaesthesia and perioperative care for such patients. Meticulous use of optimal fluids, close monitoring of the changing haemodynamics and avoidance of situations that can cause major reduction of cardiac output and fluid shifts are mandatory to achieve good clinical outcome. We searched MEDLINE using combinations of the following: anaesthesia, aortic, mitral, regurgitation, stenosis and valvular heart disease. We also hand searched textbooks and articles on valvular heart disease and anaesthesia. This article mainly focuses on the understanding the pathophysiology of valvular heart disease in patients presenting for non-cardiac surgeries in secondary and tertiary care setting.

    Population-based studies including systematic echocardiographic examinations are required to assess the prevalence of valvular heart disease. In industrialized countries, the prevalence of valvular heart disease is estimated at 2.5%. Because of the predominance of degenerative etiologies, the prevalence of valvular disease increases markedly after the age of 65 years, in particular with regard to aortic stenosis and mitral regurgitation, which accounts for 3 in 4 cases of valvular disease. Rheumatic heart disease still represents 22% of valvular heart disease in Europe. The prevalence of secondary mitral regurgitation cannot be assessed reliably but it seems to be a frequent disease. The incidence of infective endocarditis is approximately 30 cases per million individiuals per year. Its stability is associated with marked changes in its presentation. Patients are getting older and staphylococcus is now becoming the microorganism most frequently responsible. Heath care-associated infections are the most likely explanation of changes in the microbiology of infective endocarditis. In developing countries, rheumatic heart disease remains the leading cause of valvular heart disease. Its prevalence is high, between 20 and 30 cases per 1000 subjects when using systematic echocardiographic screening. In conclusion, the temporal and geographical heterogeneity illustrates the effect of socioeconomic status and changes in life expectancy on the frequency and presentation of valvular heart disease. A decreased burden of valvular disease would require the elaboration of preventive strategies in industrialized countries and an improvement in the socioeconomic environment in developing countries.

    The aim of this study is to assess the changes in the causes of valvular heart disease between 2006 and 2011 in Korea. Data were collected from the Korean National Health Insurance Service from 2006 through 2011. These data consisted of primary diagnoses related to valvular heart disease regardless of other conditions. Valvular heart disease included non-rheumatic mitral valve disorders, non-rheumatic aortic valve disorders, rheumatic mitral valve disorders, and rheumatic aortic valve disorders. Overall, the age-standardized cumulative prevalence of non-rheumatic valvular heart disease was 70.6 per 100,000 persons in 2006 and 110.3 in 2011. This represented an increase from 42.2 to 65.2 in women and from 28.4 to 45.1 in men. In particular, there was a greater increase in prevalence in patients aged 65 years or older compared with groups aged 20-44 years or 45-64 years for both genders. The age-standardized cumulative prevalence of rheumatic valve disease did not change dramatically between 2006 and 2011. The overall age-standardized cumulative prevalence of non-rheumatic valvular heart diseases increased between 2006 and 2011, especially in individuals older than 65 years. These changes should be considered in future designs of cardiovascular healthcare services in countries with a rapidly aging population. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    The optimum management of patients with valvular heart diseases requires accurate and reproducible assessment of the valvular lesion and its hemodynamic consequences. Magnetic resonance imaging (MRI) techniques, such as volume measurements, signal-void phenomena, and velocity mapping, can be used...... in an integrated approach to gain qualitative and quantitative information on valvular heart disease as well as ventricular dimensions and functions. Thus, MRI may be advantageous to the established diagnostic tools in assessing the severity of valvular heart disease as well as monitoring the lesion and predicting...... the optimal timing for valvular surgery. This paper reviews the validation of these MRI techniques in assessing valvular heart disease and discusses some typical pitfalls of the techniques, including suggestions for solutions.J. Magn.

    With widespread adoption of transcatheter aortic valve replacement, there has been a change in the approach to management of valvular heart disease. New interest has taken hold in transcatheter therapies for valvular heart disease, as well as research into pathophysiology and progression of disease. Additionally, several key trials have further refined our understanding of surgical management of valvular heart disease. This review will elucidate recent clinical trial data leading to changes in practice. There have been several landmark trials expanding the indications for transcatheter aortic valve replacement. Additionally, although still early, trials are beginning to demonstrate the feasibility and safety of transcatheter mitral valves. Options for transcatheter management of right-sided valvular disease continue to evolve, and these are areas of active investigation. The emergence of novel therapies for valvular heart disease has expanded the management options available, allowing physicians to better individualize treatment of patients with valvular heart disease. This review will focus on the recent (within 2 years) trials in this field of interest.

    Mucopolysaccharidosis type I is a genetic disorder with impaired glycosaminoglycan degradation. Cardiac pathologic involvement in this subset of patients is predominantly valvular heart disease. Valvular heart disease seen in these patients will most likely require surgical intervention in their lifetime. Only a limited amount of reports are dedicated to the cardiac surgical management of mucopolysaccharidoses. We present the case of a 32-year-old female with Hurler-Scheie syndrome who required multiple valve replacements due to progression of valvular dysfunction and decline in the quality of life. Multidisciplinary evaluation and discussion early are crucial for quality of life optimization in this cohort of patients.

    In women with valvular heart disease, pregnancy-associated cardiovascular changes can contribute to maternal, foetal and neonatal complications. Ideally, a woman with valvular heart disease should receive preconception assessment and counselling from a cardiologist with expertise in pregnancy. For women with moderate- and high-risk valve lesions, appropriate risk stratification and management during pregnancy will optimise outcomes. Pregnancy in women with high-risk lesions, such as severe aortic stenosis, severe mitral stenosis and those with mechanical valves, requires careful planning and coordination of antenatal care by a multidisciplinary team. The purpose of this overview is to describe the expected haemodynamic changes in pregnancy, review pregnancy risks for women with valvular heart disease and discuss strategies for management.

    Patients with valvular heart disease frequently have atrial fibrillation(AF) due to elevated pressure and dilatation of the left and right atria and pulmonary veins. Guidelines for valvular heart disease and AF recommend that surgical treatment for the valvular heart disease should be performed concomitantly with AF surgery. The Full-Maze procedure has evolved into the gold standard of treatment for medically refractory AF. In addition to the pulmonary vein isolation, the right and left atrial incisions of the Full-Maze procedure are designed to block potential macroreentrant pathways. According to the mechanisms of AF with valvular heart disease, the Full-Maze procedure is more effective for the patients than the pulmonary vein isolation alone.

    The aim of this article is to provide a perspective on the relative importance and contribution of different imaging modalities in patients with valvular heart disease. Valvular heart disease is increasing in prevalence across Europe, at a time when the clinical ability of physicians to diagnose and assess severity is declining. Increasing reliance is placed on echocardiography, which is the mainstay of cardiac imaging in valvular heart disease. This article outlines the techniques used in this context and their limitations, identifying areas in which dynamic imaging with cardiovascular magnetic resonance and multislice CT are expanding.

    The number of pregnancies complicated by valvular heart disease is increasing. This review describes the hemodynamic effects of clinically important valvular abnormalities during pregnancy and reviews current guideline-driven management strategies. Valvular heart disease in women of childbearing age is most commonly caused by congenital abnormalities and rheumatic heart disease. Regurgitant lesions are well tolerated, while stenotic lesions are associated with a higher risk of pregnancy-related complications. Management of symptomatic disease during pregnancy is primarily medical, with percutaneous interventions considered for refractory symptoms. Most guidelines addressing the management of valvular heart disease during pregnancy are based on case reports and observational studies. Additional investigation is required to further advance the care of this growing patient population.

    Valvular heart disease is associated with significant morbidity and mortality and often the result of congenital malformations. However, the prevalence is increasing in adults not only because of the growing aging population, but also because of improvements in the medical and surgical care of children with congenital heart valve defects. The success of the Human Genome Project and major advances in genetic technologies, in combination with our increased understanding of heart valve development, has led to the discovery of numerous genetic contributors to heart valve disease. These have been uncovered using a variety of approaches including the examination of familial valve disease and genome-wide association studies to investigate sporadic cases. This review will discuss these findings and their implications in the treatment of valvular heart disease. PMID:24743897

    After 5 years the European Society of Cardiology and the European Association for Cardio-Thoracic Surgery have released an update on the guidelines for the management of valvular heart diseases. In recent years published results of randomized trials in patients with aortic valve stenosis have resulted in updated recommendations for catheter-based prosthesis implantation (TAVI), which is now extended to patients presenting without a low risk for conventional surgical valve replacement. In mitral or tricuspid valvular disease, the recommendations for catheter-based therapies are less strong because of a lack of supportive scientific data. A special focus of these updated guidelines is on concomitant antithrombotic therapy in valvular heart disease and in the context of a combination with coronary artery disease and/or accompanying arrhythmia. Special emphasis was again put on the multidisciplinary heart team for the diagnostics and treatment of patients with valvular heart disease. In order to support the quality of treatment for patients with valvular heart disease, it is suggested that heart valve centers of excellence should be established, which have to fulfil complex personnel, structural and technological prerequisites.

    International records indicate that only 2.6% of patients with heart transplants have valvular heart disease. The study aim was to evaluate the epidemiological and clinical profile of patients with valvular heart disease undergoing heart transplantation. Between 1985 and 2013, a total of 569 heart transplants was performed at the authors' institution. Twenty patients (13 men, seven women; mean age 39.5 +/- 15.2 years) underwent heart transplant due to structural (primary) valvular disease. Analyses were made of the patients' clinical profile, laboratory data, echocardiographic and histopathological data, and mortality and rejection. Of the patients, 18 (90%) had a rheumatic etiology, with 85% having undergone previous valve surgery (45% had one or more operations), and 95% with a normal functioning valve prosthesis at the time of transplantation. Atrial fibrillation was present in seven patients (35%), while nine (45%) were in NYHA functional class IV and eight (40%) in class III. The indication for cardiac transplantation was refractory heart failure in seven patients (35%) and persistent NYHA class III/IV in ten (50%). The mean left ventricular ejection fraction (LVEF) was 26.6 +/- 7.9%. The one-year mortality was 20%. Histological examination of the recipients' hearts showed five (27.7%) to have reactivated rheumatic myocarditis without prior diagnosis at the time of transplantation. Univariate analysis showed that age, gender, LVEF, rheumatic activity and rejection were not associated with mortality at one year. Among the present patient cohort, rheumatic heart disease was the leading cause of heart transplantation, and a significant proportion of these patients had reactivated myocarditis diagnosed in the histological analyses. Thus, it appears valid to investigate the existence of rheumatic activity, especially in valvular cardiomyopathy with severe systolic dysfunction before transplantation.

    2017-09-01

    Valvular heart disease in women of childbearing age poses an increased risk of adverse maternal and fetal outcomes, and management in pregnancy can be challenging. Ideally, patients with suspected valvular disease should have preconception counseling by a multidisciplinary team including cardiologists with expertise in pregnancy and a maternal-fetal medicine specialist. Preconception planning should include a cardiac assessment of maternal risk, determination of frequency of surveillance, and a cardiovascular management plan during delivery. Women with valvular heart disease should be followed closely by a cardiologist and monitored for signs and symptoms of congestive heart failure and arrhythmias. In general, stenotic lesions may become more symptomatic in pregnancy, whereas regurgitant lesions are generally well tolerated. Left-sided valvular lesions have higher complication rates than right-sided lesions. For patients with asymptomatic valvular stenosis, medical management during pregnancy may include beta blockade and/or diuretics. Exercise stress testing prior to pregnancy in sedentary patients can be helpful to unmask symptoms and determine functional capacity. Patients with symptomatic, severe left-sided valvular obstruction have a high maternal risk of cardiovascular events during pregnancy, and percutaneous balloon valvuloplasty or surgery is recommended prior to pregnancy. The type of prosthetic valve (mechanical vs bioprosthetic) should be selected after a careful discussion with the patient. Invasive procedures are generally reserved for when medical management fails. The second trimester may be the optimal time for intervention as fetal organogenesis is complete and the cardiac positioning has not been affected by the gravid uterus.

    Valvular heart diseases from any cause are divided into two categories: stenosis and regurgitation. Acquired knowledge of the pathological aetiology and disease severity are the important clues for optimal treatment, which may be medication or combination with surgery. The non-invasive techniques have been established for valvular heart disease evaluation for many years especially in demonstrating valvular structure and assessing severity. Transthoracic echocardiography still plays the major role. However, not every case can be clearly evaluated by transthoracic echocardiography because of rib space window limitation. In the present-day practice, MRI has been extensively used for the evaluation of heart diseases in both unique and complementary categories. However, valvular heart disease assessment using cardiac MRI still remains an important challenge. PMID:27326026

    Cine-MR imaging was done in 2 normal persons and 9 patients of valvular heart disease with 2.0 T superconducting MR system (Spectro-2000; GoldStar, Korea). The MRI was undertaken using gradient echo technique with small flip angle. Repetition time (TR) was 34 msec, and echo time (TE), 18 msec. In most cases, 20 to 30 frames could be obtained during one cardiac cycle. With normal heart, high signal intensity was identified in the blood filled cardiac chambers. Transient signal void was observed near tricuspid, mitral and aortic valves due to the turbulences induced by valve opening or closure. In 6 cases of mitral valvular disease, mitral valve was identified in all cases. The valvular motion was limited revealing doming toward cardiac apex during diastole. Signal void was evident in pansystolic phase of left ventricle in all cases. Evidence of combined aortic or tricuspid valve disease were also demonstrated, revealing signal void in the corresponding cardiac chambers. Cine-MRI seemed to be not only a good non-invasive diagnostic modality for the valvular heart disease, but also an accurate modality for cardiac functional evaluation

    In 58 patients suffering from either stenosis or insufficiency of a single heart valve, gated blood pool scintigraphy was performed to determine the ejection fraction as well as the peak filling and peak ejection rates. It could be demonstrated that in patients with valvular disorders the ejection fraction was only moderately decreased, generally remaining in the lower reference range. The peak filling and ejection rates showed no pathologic changes with the exception of patients with aortic regurgitation where these rates were significantly decreased. Thus, the estimation of left ventricular peak filling and ejection rates may permit diagnosis of myocardial impairment in patients with valvular disease even under resting conditions.

    Valvular heart disease constitutes the majority of all causes of heart disease in pregnancy. In the presence of valvular heart disease, the necessary haemodynamic changes of pregnancy might cause heart failure, leading to severe maternal and fetal morbidity and even mortality. Treatment of valvular heart disease is indicated when patients experience a deterioration of symptoms and in case of a severe valvular lesion. Whether medical therapy or interventional therapy is the optimal treatment for both mother and child is unclear. To assess effectiveness and adverse effects of the different treatment modalities of valvular heart disease in pregnancy to improve maternal and neonatal outcomes. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 March 2011), EMBASE (1980 to 23 March 2011) and the reference lists of background review articles. Randomised controlled trials, quasi-randomised controlled and cluster-randomised controlled trials comparing medical therapy with percutaneous or surgical intervention for the treatment of valvular heart disease in pregnancy. We identified no (randomised) controlled trials to assess the effectiveness and adverse effects of the treatment of valvular heart disease in pregnancy. There were no randomised controlled trials, quasi-randomised controlled trials or cluster-randomised trials identified from the search strategy. There is insufficient evidence to define the most effective treatment of valvular heart disease in pregnancy to improve maternal and neonatal outcomes.

    In spite of the great number of imaging procedures available, it is still difficult to quantify the severity of valvular heart disease. Dynamic MRI offers new approaches to visualize the turbulent blood flow through stenosed or insufficient heart valves. In addition, it is possible to assess the severity of valvular insufficiency based on precise measurements of rigth- and left-ventricular stroke volumes or of systemic and pulmonary flow. Valvular stenoses are difficult to quantify by MRI because flow velocity measurements based on phase analysis can only be made at low flow rates at present. Some progress may be achieved by further shortening of echo times. In patients with cardiac valve replacement MRI is often superior to other imaging procedures because variable imaging planes facilitate differentiation between transvalvular and paravalvular leaks. Additionally, the severity of valvular incompetence can be assessed in such cases in the same way as in patients with insufficiency of the native heart valve. (orig.) [de

    Valvular heart diseases occur frequently in Tunisia, but no precise statistics are available. To analyse the characteristics of patients with abnormal valvular structure and function, and to identify the aetiological spectrum, treatment and outcomes of valvular heart disease in a single cardiovascular centre in Tunisia. This retrospective study included patients with abnormal valvular structure and function, who were screened by transthoracic echocardiography at a single cardiology department between January 2010 and December 2013. Data on baseline characteristics, potential aetiology, treatment strategies and discharge outcomes were collected from medical records. There were 959 patients with a significant valvular heart disease (mean age 53±17years; female/male ratio 0.57). Valvular heart disease was native in 77% of patients. Mitral stenosis was the most frequent lesion (44.1%), followed by multiple valve disease (22.3%). Rheumatic origin (66.6%) was the most frequent aetiology, followed by degenerative (17.2%) or ischaemic (8.1%) causes, endocarditis (1.4%) and congenital (0.9%) causes. Native valve disease was severe in 589 patients (61.4%). Percutaneous mitral balloon valvuloplasty was performed in 36.9% of patients with mitral stenosis. Among patients with severe valvular heart disease, surgical treatment was indicated for 446 (75.7%) patients. Only 161 (36.1%) patients were finally operated. Postoperative mortality was 13.6% for all valvular heart diseases. This retrospective study has shown that the main cause of valvular heart disease in Tunisia is rheumatic fever. Mitral stenosis and multiple valve disease are the most frequent valvular heart diseases in Tunisia. Percutaneous mitral balloon valvuloplasty and prosthetic valve replacement are the preferred treatment methods for valvular heart disease. Copyright © 2016. Published by Elsevier Masson SAS.

    Echocardiographic 3D-guided 2D planimetry can improve the accuracy of valvular disease assessment. Acquisition of 3D pyramidal dataset allows subsequent multiplanar reconstruction with accurate orthogonal plane alignment to obtain the correct borders of an anatomic orifice or flow area. Studies examining the 3D-guided 2D planimetry approach in left-sided valvular heart disease were identified and reviewed. The strongest evidence exists for estimating mitral valve area in patients with rheumatic mitral valve stenosis and vena contracta area in patients with mitral regurgitation (both primary and secondary). 3D-guided approach showed excellent feasibility and reproducibility in most studies, as well as time efficiency and good correlation with reference and comparator methods. Therefore, 3D-guided 2D planimetry can be used as an important clinical tool in quantifying left-sided valvular heart disease, especially mitral valve disorders. © 2018 Wiley Periodicals, Inc.

    Sleep disordered breathing (SDB) is common in patients with chronic heart failure secondary to non-valvular heart disease; however, the prevalence and characteristics of SDB in patients with rheumatic valvular heart disease (RVHD) are unclear. This study was designed to determine the prevalence, characteristics, and risk factors for SDB in RVHD patients. A cross-sectional study was conducted in 260 RVHD patients. The following data were recorded: types of heart valve lesions, electrocardiographic, echocardiographic, arterial blood gas analysis findings, baseline medication, 6-minute walk test (6MWT) distance, and sleep parameters. Compared to patients with single leftsided valve lesions, patients with left- and rightsided valve lesions had a higher prevalence of SDB (46.2% vs. 31.2%, p = 0.013); the increased prevalence of SDB only involved central sleep apnea (CSA) (31.1% vs. 14.1%, p = 0.001). Patients with obstructive sleep apnea (OSA) or CSA were older and had a shorter 6MWT distance, lower left ventricle ejection fraction and PaO₂, a longer lung-to-finger circulation time, and a higher prevalence of atrial fibrillation (AF) and hypertension (all p < 0.05) as compared with patients without SDB. Multinomial logistic regression analysis showed that PaO2 ≤ 85 mm Hg was the only risk factor for OSA. Male gender, AF, 6MWT distance ≤ 300 m, PaO₂ ≤ 85 mmHg, and PaCO₂ ≤ 40 mm Hg were risk factors for CSA. Patients with RVHD had a high prevalence of SDB (predominantly CSA). RVHD patients with SDB, particularly those who had CSA, manifested more severe symptoms and greater impairment of cardiac function. Assessments of clinical manifestations of cardiac dysfunction may be important for predicting the risk factors for SDB.

    Patients with valvular heart disease or with a prosthetic heart valve replacement are seen with increasing frequency in clinical practice. The medical care and evaluation of patients with valvular heart disease before valve surgery, but also the post-operative treatment is complex and managed by general practitioners, cardiologists and cardiac surgeons. In this mini-review we will first discuss the preoperative assessment of the two most common valvulopathies, aortic stenosis and mitral regurgitation. Then we will discuss the post-operative care, which includes the management of anticoagulation, serial follow up and as well as the diagnostic assessment of complications such as thromboembolism, hemolysis, endocarditis and valve dysfunction.

    Full Text Available The pattern of valvular heart disease is changing in Western populations. There are implications for Africa as healthcare improves and people live longer. Over the last half century in Western countries there has been a change in the incidence of valvular heart disease from a rheumatic cause to one of degeneration. Until the age of 64 years all moderate to severe valve disease affects less than 2%. In the group aged 64 – 75 years the proportion increases to 4 - 8% and after age 75 years it rises to 12 - 13%. Mitral incompetence (regurgitation and aortic stenosis contribute to the majority of cases. Mitral stenosis is much more common in patients who have had rheumatic heart disease. As the population ages the healthcare burden of valvular heart disease will become greater.

  13. Valvular Disorders in Carcinoid Heart Disease

    Directory of Open Access Journals (Sweden)

    Shi-Min Yuan

    Full Text Available Abstract Carcinoid heart disease is a rare but important cause of intrinsic right heart valve disorders leading to right heart failure. Occasionally, left-sided heart valves may also be involved. The characteristic cardiac pathological findings of carcinoid heart disease are endocardial thickening as a result of fibrous deposits on the endocardium. Echocardiographic examination and right heart catheterization are very useful for the diagnosis of the lesion. If more cardiac valves are affected, multiple valve replacement should be considered. The management of the pulmonary valve lesion depends on the extent of the diseased valve, either by valvulotomy, valvectomy, or valve replacement. Percutaneous valve implantations in the pulmonary and in the inferior vena cava positions have been advocated for high-risk patients.

    In the current era, diagnosis and follow-up of valvular heart disease is performed noninvasively using echocardiography. In some cases, the results of echocardiographic evaluation are inconclusive or discrepant with the patient's clinical symptoms. In such cases, a well-planned and executed cardiac catheterization is invaluable to clarify the clinical dilemma and assist in planning further management. This article reviews the indications, technique, and interpretation of cardiac catheterization in the setting of valvular stenosis and regurgitation. Copyright © 2017 Elsevier Inc.

    As a key feature of the updates, early intervention of valvular heart disease is highlighted in the 2014 AHA/ACC guideline for the management of patients with valvular heart disease. This article reviewed the new guideline in regards to the issue of early intervention of diseases such as aortic stenosis, aortic insufficiency, mitral stenosis, mitral insufficiency, tricuspid insufficiency, and infective endocarditis, with discussion on the related topics according to the authors' understanding and practical experience in China. We conclude that valvular heart disease should receive early intervention and attention should also be paid on the progress of disease.

    The prevalence of valvular heart disease is increasing as the population ages. In diagnosing individuals with valve disease, echocardiography is the primary imaging modality used by clinicians both for initial assessment and for longitudinal evaluation. However, in some cases cardiovascular magnetic resonance has become a viable alternative in that it can obtain imaging data in any plane prescribed by the scan operator, which makes it ideal for accurate investigation of all cardiac valves: aortic, mitral, pulmonic, and tricuspid. In addition, CMR for valve assessment is noninvasive, free of ionizing radiation, and in most instances does not require contrast administration. The objectives of a comprehensive CMR study for evaluating valvular heart disease are threefold: (1) to provide insight into the mechanism of the valvular lesion (via anatomic assessment), (2) to quantify the severity of the valvular lesion, and (3) to discern the consequences of the valvular lesion.

The role of NPs in the management of valvular heart disease is a growing area of investigation. NPs have much potential in the assessment of asymptomatic patients with hemodynamically significant valvular lesions who have traditionally been excluded from consideration of surgical intervention. NPs also have a role in the risk stratification of these patients as well as in routine surveillance and monitoring. Together with echocardiographic data and functional status, NPs are being incorporated into the management of valvular heart disease. In this review we examine the evidence for the role of natriuretic peptides in assessment of VHD.

    The definition of non-valvular atrial fibrillation (NVAF) is controversial. We aimed to assess the impact of valvular heart disease on stroke prevention strategies in NVAF patients. The RAMSES study was a multicenter and cross-sectional study conducted on NVAF patients (ClinicalTrials.gov identifier NCT02344901). The study population was divided into patients with significant valvular disease (SVD) and non-significant valvular disease (NSVD), whether they had at least one moderate valvular disease or not. Patients with a mechanical prosthetic valve and mitral stenosis were excluded. Baseline characteristics and oral anticoagulant (OAC) therapies were compared. In 5987 patients with NVAF, there were 3929 (66%) NSVD and 2058 (34%) SVD patients. The predominant valvular disease was mitral regurgitation (58.1%), followed by aortic regurgitation (24.1%) and aortic stenosis (17.8%). Patients with SVD had higher CHA 2 DS 2 VASc [3.0 (2.0; 4.0) vs. 4.0 (2.0; 5.0), p valvular heart disease with the predominance of mitral regurgitation. Patients with SVD were at greater risk of stroke and bleeding compared to patients with NSVD. Although patients with mitral regurgitation should be given more aggressive anticoagulant therapy due to their higher risk of stroke, they are undertreated compared to patients with aortic valve diseases.

    Endocarditis has been reported in patients with valvular heart disease who have undergone acupuncture treatment, although most have been associated with the use of semi-permanent needles. This has led reviewers to suggest that acupuncture may not only be contraindicated in such patients but that prophylactic antibiotics should be given. This study investigated the use of acupuncture treatment in patients with proven valvular heart disease and observed whether endocarditis developed in such patients. All patients in a single-handed GP practice with proven valvular heart disease, including those with prosthetic valves, were identified over a ten-year period. Those who had undergone acupuncture treatment underwent a clinical examination and diagnostic tests, which focused on the signs, symptoms and laboratory criteria for the diagnosis of endocarditis and included a transthoracic echocardiogram. Autopsy findings were reviewed in any patient who died. Based on these clinical and laboratory data, using the modified Duke's criteria for the diagnosis of endocarditis, patients were identified as having definite or possible endocarditis, or the diagnosis was rejected. All patients underwent brief acupuncture with no skin disinfectant and no prophylactic antibiotics were given. Semi-permanent needles were avoided. Thirty-six patients with valvular heart disease underwent a total of 479 acupuncture treatments over a ten-year period. The median number of treatments was 9 (range 1-72), with a follow-up after treatment of 5.75 years (range 0.5-10 years). Definite endocarditis was not found in any patient, but two patients had possible endocarditis, eventually discounted by both negative blood cultures and echocardiography. In conclusion, brief acupuncture was safe in this small cohort of valvular heart disease patients and no case of endocarditis was detected over a ten-year period.

In this regard, the analysis of the effectiveness of a combination regimen of 74 patients with valvular congenital heart diseases complicated with infective endocarditis. Given the indications for surgical correction operative technique features and possible technical difficulties in carrying out such operations, due to the inflammatory changes and tissue destruction, and ways to overcome them. For the correction of metabolic disorders in the postoperative period, 47 patients (main group) was appointed Reamberin: once, intravenous drip 400 ml/day during the first 5 days after surgery. 27 patients (control group) was conducted infusion therapy depending on the severity of the condition according to the classical scheme. In addition to standard clinical and laboratory examination, to assess the effectiveness of Reamberin was investigated catalase activity of CPK in blood serum in the dynamics of observation (1, 3 and 5 days after surgery). It is revealed that surgical approach, used in complex treatment of patients with valvular congenital heart diseases, including reorganization of the cavities of the heart, increasing the frequency of joints and the use of reinforcing strips of synthetic material that prevents the cutting of sutures through the inflamed tissue has achieved good short-and long-term results. Infective endocarditis and destruction of the valvular annulus fibrosus the use of a frame of strips of polytetrafluoroethylene allows you to restore its integrity and to implant a mechanical prosthesis.

    Stress echocardiography is increasingly used in the management of patients with valvular heart disease and can aid in evaluation, risk stratification and clinical decision making in these patients. Evaluation of symptoms, exercise capacity and changes in blood pressure can be done during the exercise portion of the test, whereas echocardiographic portion can reveal changes in severity of disease, pulmonary artery pressure and left ventricular function in response to exercise. These parameters, which are not available at rest, can have diagnostic and prognostic importance. In this article, we will review the indications and diagnostic implications, prognostic implications, and clinical impact of stress echocardiography in decision making and management of patients with valvular heart disease.

    Cardiac valvular disease as consequence of radiation and chemotherapy during treatment for malignancy is growing in its awareness. While the overwhelming emphasis in this population has been on the monitoring and preservation of left ventricular systolic function, we are now developing a greater appreciation for the plethora of cardiac sequelae beyond this basic model. To this end many institutions across the country have developed cardio-oncology programs, which are collaborative practices between oncologists and cardiologists in order to minimize a patient's cardiovascular risk while allowing them to receive the necessary treatment for their cancer. These programs also help to recognize early nuanced treatment complications such as valvular heart disease, and provide consultation for the most appropriate course of action. In this article we will discuss the etiology, prevalence, diagnosis, and current treatment options of valvular heart disease as the result of chemotherapy and radiation.

    Full Text Available BACKGROUND Diseases of heart valves constitute a major cause of cardiovascular morbidity and mortality worldwide. In developing countries, Rheumatic Heart Disease (RHD continues to be the predominant form of valvular heart disease. The current study was undertaken at a Tertiary Care Institute with an objective of establishing distribution and different patterns of valvular heart diseases by echocardiography. MATERIALS AND METHODS 17,625 consecutive first time Echocardiograms performed between January 2016 and December 2016 were analysed. Echo was performed by consultant cardiologists using Philips HD11XE and Aloka SSD4000 machine following ASE guidelines. Applying exclusion criteria of trivial and functional regurgitant lesions yielded a total of 632 cases of organic valvular heart diseases. RESULTS In our study 632 patients were diagnosed with valvular heart disease, out of which 428 patients (67.7% were diagnosed with Rheumatic Heart Disease. Mitral valve was the most commonly affected followed by aortic and tricuspid valves. The least commonly affected valve was pulmonary valve. In Rheumatic heart disease, most common isolated lesion reported was MS with MR, most commonly reported in females between 21 - 40 years’ age group. CONCLUSION In non-RHD group, mitral valve prolapse (21.3% was the commonest lesion reported followed by calcific degenerative aortic valve (6.17% and congenital bicuspid aortic valve (3.4%; 118 patients were reported with multivalvular lesion. MS + MR + AR was the commonest multivalvular lesion found in 65 patients (55.08%.

    Cardiac surgery is in the midst of a practice revolution. Traditionally, surgery for valvular heart disease consisted of valve replacement via conventional sternotomy using cardiopulmonary bypass. However, over the past 20 years, the increasing popularity of less-invasive procedures, accompanied by advancements in imaging, surgical instrumentation, and robotic technology, has motivated and enabled surgeons to develop and perform complex cardiac surgical procedures through small incisions, often eliminating the need for sternotomy or cardiopulmonary bypass. In addition to the benefits of improved cosmesis, minimally invasive mitral valve surgery was pioneered with the intent of reducing morbidity, postoperative pain, blood loss, hospital length of stay, and time to return to normal activity. This article reviews the current state-of-the-art of minimally invasive approaches to the surgical treatment of valvular heart disease. Copyright © 2014 Elsevier Inc. All rights reserved.

    Twenty two patients with rheumatic valvular heart disease - 21 having a history of heart failure - were studied using direct coronary injection of /sup 99m/Tc labelled MAA particles during the course of hemodynamic and arteriographic studies. Myocardial perfusion deficit patterns have been shown to be consistent or indicative of either patchy, regional or gross ischemia. In patients with history of documented heart failure 90% (18 cases) had ischemic perfusion deficit in the involved ventricle. We conclude that diminished myocardial blood flow is an important mechanism contributing to the development of heart failure.

    Drug-induced valvular heart disease (DI-VHD) remains an under-recognized entity. This report describes a heart valve replacement which was complicated by intractable systemic pulmonary arterial hypertension in a 61-year-old female with severe restrictive mitral and aortic disease. The diagnosis of valvular disease was preceded by a history of unexplained respiratory distress. The patient had been exposed to benfluorex for 6.5 years. The diagnostic procedure documented specific drug-induced valvular fibrosis. Surgical mitral and aortic valve replacement was performed. Heart valve replacement was postoperatively complicated by unanticipated disproportionate pulmonary hypertension. This issue was fatal despite intensive care including prolonged extracorporeal life support. Benfluorex is a fenfluramine derivative which has been marketed between 1976 and 2009. Although norfenfluramine is the common active and toxic metabolite of all fenfluramine derivatives, the valvular and pulmonary arterial toxicity of benfluorex was much less known than that of fenfluramine and dexfenfluramine. The vast majority of benfluorex-induced valvular heart disease remains misdiagnosed as hypothetical rheumatic fever due to similarities between both etiologies. Better recognition of DI-VHD is likely to improve patient outcome.

    Valvular heart disease frequently occurs as a consequence of premature atherosclerosis in individuals with familial hypercholesterolemia (FH). Studies have primarily focused on aortic valve calcification in heterozygous FH, but there is paucity of data on the incidence of valvular disease in homozygous FH. We performed echocardiographic studies in 33 relatively young patients (mean age: 26 years) with homozygous FH (mean LDL of 447 mg/dL, 73% on LDL apheresis) to look for subclinical valvulopathy. Twenty-one patients had evidence of valvulopathy of the aortic or mitral valves, while seven subjects showed notable mitral regurgitation. Older patients were more likely to have aortic valve calcification (>21 versus ≤21 years: 59% versus 12.5%; p = 0.01) despite lower LDL levels at the time of the study (385 versus 513 mg/dL; p = 0.016). Patients with valvulopathy were older and had comparable LDL levels and a lower carotid intima-media thickness. Our data suggests that, in homozygous FH patients, valvulopathy (1) is present across a wide age spectrum and LDL levels and (2) is less likely to be influenced by lipid-lowering treatment. Echocardiographic studies that focused on aortic root thickening and stenosis and regurgitation are thus likely an effective modality for serial follow-up of subclinical valvular heart disease.

    Valvular heart disease (VHD) is caused by either damage or defect in one of the four heart valves, aortic, mitral, tricuspid or pulmonary. Defects in these valves can be congenital or acquired. Age, gender, tobacco use, hypercholesterolemia, hypertension, and type II diabetes contribute to the risk of disease. VHD is an escalating health issue with a prevalence of 2.5% in the United States alone. Considering the likely increase of the aging population worldwide, the incidence of acquired VHD is expected to increase. Technological advances are instrumental in identifying congenital heart defects in infants, thereby adding to the growing VHD population. Almost one-third of elderly individuals have echocardiographic or radiological evidence of calcific aortic valve (CAV) sclerosis, an early and subclinical form of CAV disease (CAVD). Of individuals ages >60, ~2% suffer from disease progression to its most severe form, calcific aortic stenosis. Surgical intervention is therefore required in these patients as no effective pharmacotherapies exist. Valvular calcium load and valve biomineralization are orchestrated by the concerted action of diverse cell-dependent mechanisms. Signaling pathways important in skeletal morphogenesis are also involved in the regulation of cardiac valve morphogenesis, CAVD and the pathobiology of cardiovascular calcification. CAVD usually occurs without any obvious symptoms in early stages over a long period of time and symptoms are identified at advanced stages of the disease, leading to a high rate of mortality. Aortic valve replacement is the only primary treatment of choice. Biomarkers such as asymmetric dimethylarginine, fetuin-A, calcium phosphate product, natriuretic peptides and osteopontin have been useful in improving outcomes among various disease states. This review, highlights the current understanding of the biology of VHD, with particular reference to molecular and cellular aspects of its regulation. Current clinical questions

Echocardiographic studies that focused on aortic root thickening and stenosis and regurgitation are thus likely an effective modality for serial follow-up of subclinical valvular heart disease.

    There is a clinically staggering burden of disease stemming from cerebrovascular events, of which a majority are ischemic in nature and many are precipitated by atrial fibrillation (AF). AF can occur in isolation or in association with myocardial or structural heart disease. In the latter case, and when considering health at an international level, congenital and acquired valve-related diseases are frequent contributors to the current pandemic of AF and its clinical impact. Guidelines crafted by the American Heart Association, American College of Cardiology, European Society of Cardiology and Heart Rhythm Society underscore the use of vitamin K antagonists (VKAs) among patients with valvular heart disease, particularly in the presence of concomitant AF, to reduce the risk of ischemic stroke of cardioembolic origin; however, the non-VKAs, also referred to as direct, target-specific or new oral anticoagulants (NOACs), have not been actively studied in this particular population. In fact, each of the new agents is approved in patients with AF not caused by a valve problem. The aim of our review is to carefully examine the available evidence from pivotal phase 3 clinical trials of NOACs and determine how they might perform in patients with AF and concomitant valvular heart disease.

    Objective: To evaluate pulmonary hypertension (PH) using first-pass radionuclide angiography in patients with valvular heart disease. Methods: One hundred and forty patients (54 males, 86 females, average age of 44.75±10.84) with valvular disease were included in this study. Swan-Ganz thermodilution catheterization, echocardiography and first-pass radionuclide angiography were performed on all patients before surgery. Patients were divided into four groups: pulmonary artery pressure (PAP) normal group [mean PAP (MPAP)<20 mm Hg(1mm Hg=0.133 kPa)]; PAP slightly risen group (20 mm Hg≤MPAP<30 mm Hg); PAP moderately risen group (30 mm Hg≤MPAP<50 mm Hg); PAP highly risen group (MPAP≥50 mm Hg). Thirteen subjects with coronary heart disease and 40 normal subjects (36 males, 17 females, average age of 46.30±11.19) were included as control group. First-pass radionuclide angiography was performed on these subjects, Swan-Ganz thermodilution catheterization was performed on patients with coronary heart disease. Results: 1) Lung equilibrium time (LET) values by first-pass radionuclide angiography were (16.88±5.12), (15.89±4.69), (18.56±3.04), (25.37±5.89), (37.69±6.25) and (61.33±10.14) s in coronary heart disease group, normal subject group and four valvular heart disease groups, respectively. The differences were significant among four valvular heart disease groups; and among control group, PAP slightly risen group, PAP moderately risen group, PAP highly risen group (P<0.001). 2) Correlation coefficient between LET and MPAP from the afloat catheter manometer was 0.88 and between systolic PAP (SPAP) from echocardiography and SPAP from the afloat catheter manometer was 0.64. 3) Agreement was 71%, 78%, 81%, 100% between LET and MPAP in four valvular heart disease groups, respectively. 4) Sensitivity, specificity and accuracy of PAP using LET measuring was 85%, 79% and 83%, respectively. Conclusion: First-pass radionuclide angiography is an accurate and noninvasive

    Data on the prevalence of valvular heart disease in very old individuals are scarce and based mostly on in-hospital series. In addition, the potential detrimental effect of valvular heart disease on the activities of daily living is unknown. The present study evaluated the prevalence of significant valvular heart disease and the impact of valvular heart disease on the activities of daily living in community dwelling nonagenarians. Nested within the Leiden 85-plus study, a population based follow-up study of the oldest old, a sample of 81 nonagenarians was recruited. The left ventricular (LV) dimensions, function and the presence and severity of heart valvular disease were evaluated by echocardiography. Significant valvular heart disease included any mitral or aortic stenosis severity, moderate or severe mitral regurgitation, moderate or severe aortic regurgitation and moderate or severe tricuspid regurgitation. Activities of daily living were assessed using the Groningen Activity Restriction Scale (GARS). LV cavity diameters (end-diastolic diameter 47 +/- 8 mm, end-systolic diameter 30 +/- 8 mm) and systolic LV function (LV ejection fraction 66 +/- 13%) were within normal for the majority of the participants. Significant valvular disease was present in 57 (70%) individuals, with mitral regurgitation and aortic regurgitation as the most frequent valve diseases (49% and 28% respectively). The GARS score between individuals with and without significant valvular heart disease was similar (36.2 +/- 9.2 vs. 34.4 +/- 13.2, p = 0.5). Nonagenarian, outpatient individuals have a high prevalence of significant valvular heart disease. However, no relation was observed between the presence of significant valvular heart disease and the ability to perform activities of daily living.

    Valvular heart disease is a group of complex entities with varying etiologies and clinical presentations. There are a number of imaging tools available to supplement clinical evaluation of suspected valvular heart disease, with echocardiography being the most common and clinically established, and more recent emergence of computed tomography and magnetic resonance imaging as additional supportive techniques. Yet even with these newer and more sophisticated modalities, chest radiography remains one of the earliest and most common diagnostic examinations performed during the triage of patients with suspected cardiac dysfunction. Recognizing the anatomic and pathologic features of cardiac radiography including the heart's adaptation to varying hemodynamic changes can provide clues to the radiologist regarding the underlying etiology. In this article, we will elucidate several principles relating to chamber modifications in response to pressure and volume overload as well as radiographic appearances associated with pulmonary fluid status and cardiac dysfunction. We will also present a pattern approach to optimize analysis of the chest radiograph for valvular heart disease, which will help guide the radiologist down a differential diagnostic pathway and create a more meaningful clinical report.

    To estimate pulmonary hypertension, we measured postural differences in pulmonary blood flow for the lateral decubitus positions on perfusion lung scintigrams with Tc-99 m macro-aggregated albumin, applying the method devised by Tanaka et al (Eur J Nucl Med 17: 320-326, 1990). Utilizing a scintillation camera coupled to a minicomputer system, changes in the distribution of pulmonary blood flow caused by gravitational effects, namely, changes in the total count ratios for the right lung versus the left lung in the right and left lateral decubitus positions (R/L), were obtained for 44 patients with lung disease, 95 patients with valvular heart disease, and 23 normal subjects. Mean standard deviation in the R/L ratios was 3.09{+-}1.28 for the normal subjects, 1.97{+-}0.89 for the patients with lung disease, and 1.59{+-}0.59 for the patients with valvular heart disease. The R/L ratios correlated with mean pulmonary arterial pressure and cardio-thoracic ratios in the lung disease and valvular heart disease groups, with pulmonary arteriolar resistance in the former, and with pulmonary capillary wedge pressure in the latter. Defining pulmonary hypertension (>20 mmHg) as an R/L ratio of less than 1.81, which is the mean-1 standard deviation for normal subjects, the sensitivity and the specificity of the R/L ratio for the diagnosis of pulmonary hypertension were 62.9% and 76.2%, respectively, for the lung disease patients, and 80.3% and 61.8%, respectively, for the valvular heart disease patients. This method seems to be useful for the pathophysiologic evaluation of pulmonary perfusion in cases of lung disease and valvular heart disease. (author)

    The year 2005 has been rich in publications concerning valvular heart disease. In France, this year has been dominated by the publication of the French Society of Cardiologists' guidelines on the operative and interventional indications for acquired valvular heart disease: discussed and accepted formal indications based on the evidence in the literature. Non-ischaemic mitral insufficiency has been the subject of a major study that showed the high prognostic significance of echographic measuring of the area of the regurgitating orifice; patients with a surface > or =40 mm2 had a worse long-term prognosis and should undergo surgery early. The prognostic significance of BNP in valvular heart disease, such as mitral insufficiency and aortic stenosis, also became apparent. BNP is being used more and more for risk stratification for these conditions. The significance of anti-arrhythmic surgery combined with a mitral procedure has confirmed the harmful effect of atrial fibrillation, before and after the mitral surgery. The first randomised study into the use of statins to slow the progression of aortic stenosis was unfortunately disappointing, despite the various unrandomised studies that had opened a therapeutic pathway for this pathology, for which the prevalence is continually rising due to the ever increasing life expectancy. In mitral stenosis, a randomised study showed the long-term value of mitral commissurotomy in percutaneous mitral valvuloplasty, giving identical long-term results, in terms of mitral area, to those obtained with the classic Inoué balloon. In infectious endocarditis, surveys have confirmed the seriousness of this pathology as well as the slight advances in its prophylaxis. Other studies have confirmed the frequency and the severity of emboli, endocarditis due to Staphylococcus aureus, and the low risk of recurrence for endocarditis with the more and more accepted short course antibiotic treatment for patients undergoing surgery. Of course, this

    It is presumed that echocardiographic laboratory accreditation leads to improved quality, but there are few data. We sought to compare the quality of echocardiographic examinations performed at accredited versus nonaccredited laboratories for the evaluation of valvular heart disease. We enrolled 335 consecutive valvular heart disease subjects who underwent echocardiography at our institution and an external accredited or nonaccredited institution within 6 months. Completeness and quality of echocardiographic reports and images were assessed by investigators blinded to the external laboratory accreditation status and echocardiographic results. Compared with nonaccredited laboratories, accredited sites more frequently reported patient sex (94% versus 78%; P heart disease. Future quality improvement initiatives should highlight the importance of high-quality color Doppler imaging and echocardiographic quantification to improve the accuracy, reproducibility, and quality of echocardiographic studies for valvular heart disease. © 2017 American Heart Association, Inc.

    The aim of this study was to test the hypothesis that normothermic cardiopulmonary bypass (CPB) is as effective as hypothermic CPB in terms of cardiac protection (cTnI level) and outcome in patients with valvular heart disease. Prospective randomized study. A tertiary cardiothoracic referral center. 140 patients who had valvular heart disease, with/without coronary artery disease, surgically treated under CPB. The patients were allocated randomly to undergo either hypothermic (temperature [T], 31 °C-32 °C) or normothermic CPB (T>36 °C). The primary endpoint was the dynamics of troponin I. The secondary endpoints were ventilation time, the need for inotropic support, intensive care unit (ICU) and hospital stay durations, complications, and mortality. There were no significant intergroup differences in dynamics of troponin I. Ventilation time was significantly lower in the hypothermic group (6 (5-9) and 8 (5-12); p = 0.01). Normothermic CPB in patients with valvular heart disease was as effective as hypothermic perfusion in terms of myocardial protection after the surgery assessed by cTnI release. The short ventilation duration in patients who underwent hypothermic CPB needs to be confirmed in a future investigation. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Introduction Alkaptonuria (also known as ochronosis is a genetic disorder characterised by the accumulation of homogentisic acid deposits in connective tissue. In rare cases, ochronosis can cause valvular heart disease. Case presentation We present the case of a 68-year-old Caucasian man with alkaptonuria-associated degenerative valvular defects with aortic, mitral and tricuspid valve insufficiency. The patient did not have any cardiac complaints and was referred to our clinic for evaluation of a conspicuous new heart murmur. Conclusion This case report shows that early diagnosis of cardiovascular ochronosis gives us the opportunity to use conservative treatment to slow down the progression of valvular dysfunction.

    Full Text Available Patients with valvular heart disease suffer from atrial fibrillation for more than 12 months after valve surgery and have a low probability of remaining in sinus rhythm. We performed an intra-operative procedure similar to surgical maze ІІІ procedure for conversion of this arrhythmia to sinus rhythm. We did this study to evaluate the efficacy of this procedure to restore the sinus rhythm in patients with valvular heart disease. 28 patients with valvular heart disease and chronic persistent atrial fibrillation underwent different combinations of valve surgery and concomitant reduction of left and right atrial size and resection of both atrial auricles in Shahid Madani cardiothoracic center from September 2004 to October 2008. The procedure for atrial fibrillation treatment was performed with cardiopulmonary bypass and after mitral valve replacement. There was one in-hospital death postoperatively because of respiratory failure, but no other complication till 6 months after the operation. Out of 28 patients, 23 were in sinus rhythm one week after the operation, one patient had junctional rhythm after the operation that restored to sinus rhythm and 4 patients had persistent atrial fibrillation. During the 12-month follow up, atrial fibrillation was corrected in 82.14%. Doppler echocardiography in these patients with sinus rhythm demonstrated good atrial contractility. This procedure on both atria is effective and less invasive than the original maze procedure to eliminate the atrial fibrillation, and can be performed in patients with valvular heart disease without increasing the risk of operation.

    For the determination of the prognosis of the acquired valvular heart disease, many diagnostic tools such as, echocardiogram, computerized RI cardiac scan, cardiac catheterization and cardiac angiography are now widely used. Among these, the cineangiography offers the most accurate and objective values in quantitation of the left ventricular performance, which is thought to be an essential prognostic factor of the valvular heart disease. Although many authors differ their opinions, increased end diastolic volume is generally understood in two ways: The one as an indicator of compensatory mechanism for the changed hemodynamics of the heart and the other as a parameter of deteriorated left ventricular performance. Authors analyzed EDV, ESV, EF, EDP and angiographic grade of regurgitation in 97 cases of the acquired valvular heart disease and results are as follows. 1. Mean EDVs are 226.2 ml/m 2 in AI + MI, 167.2 ml/m 2 in AI, 155.6 ml/m 2 in MI and 98.3 ml/m 2 in MS respectively. 2. Mean ESVs are 101.1 ml/m 2 in AI + MI, 84.1 ml/m 2 in AI, 66.5 ml/m 2 in MI and 46.4 ml/m 2 in MS respectively. 3. Mean EFs are 0.56 in AI + MI, 0.55 in AI, 0.57 in MI and 0.54 in MS respectively. 4. There are higher correlations between ESV and EF than between EDV and EF. 5. There are no significant correlation between EDP and EDV in all disease entities except AI, in which large EDV relatively correlates with high EDP. 6. In AI, EDV, ESV, EF and angiographic grade of regurgitation show close correlations between each other. 7. In MI with higher grade of regurgitation, ESV seems to be more sensitive indicator of left ventricular performance than EF. In MI with lower grade of regurgitation, EF seems to be more sensitive indicator of left ventricular performance than ESV. 8. In AI + MI, EDV, ESV and EDP show higher values than in any other disease involving single valve alone, but there are no correlations between ventricular volumes and grades of regurgitations. 9.

    The main indications for cardiac magnetic resonance imaging (MRI) in the evaluation of valvular heart disease are pathologies of the aortic and pulmonary valve. For mitral and tricuspid valve pathologies MRI is not the first line modality as these are usually well visualized by echocardiography. The advantages of MRI in valvular heart disease are a high reliability in the evaluation of ventricular volumes and function as well as the assessment of the perivalvular arterial or atrial structures. This reliability and the limitless access to any imaging plane partially compensates for the lower temporal and spatial resolution in comparison to echocardiography. In patients with congenital heart disease, cardiac MRI is established as a valuable diagnostic tool in daily clinical management, especially for the evaluation of pulmonary valve defects. Nevertheless, echocardiography remains the first-line diagnostic imaging tool for the foreseeable future. (orig.) [de

    Full Text Available Background: Although atrial fibrillation (AF, a common arrhythmia, frequently presents in patients with underlying valvular disease, its hemodynamic contributions are not fully understood. The present work aimed to computationally study how physical conditions imposed by pathologic valvular anatomy act on AF hemodynamics. Methods: We simulated AF with different severity grades of left-sided valvular diseases and compared the cardiovascular effects that they exert during AF, compared to lone AF. The fluid dynamics model used here has been recently validated for lone AF and relies on a lumped parameterization of the four heart chambers, together with the systemic and pulmonary circulation. The AF modelling involves: (i irregular, uncorrelated and faster heart rate; (ii atrial contractility dysfunction. Three different grades of severity (mild, moderate, severe were analyzed for each of the four valvulopathies (AS, aortic stenosis, MS, mitral stenosis, AR, aortic regurgitation, MR, mitral regurgitation, by varying–through the valve opening angle–the valve area. Results: Regurgitation was hemodynamically more relevant than stenosis, as the latter led to inefficient cardiac flow, while the former introduced more drastic fluid dynamics variation. Moreover, mitral valvulopathies were more significant than aortic ones. In case of aortic valve diseases, proper mitral functioning damps out changes at atrial and pulmonary levels. In the case of mitral valvulopathy, the mitral valve lost its regulating capability, thus hemodynamic variations almost equally affected regions upstream and downstream of the valve. In particular, the present study revealed that both mitral and aortic regurgitation strongly affect hemodynamics, followed by mitral stenosis, while aortic stenosis has the least impact among the analyzed valvular diseases. Discussion: The proposed approach can provide new mechanistic insights as to which valvular pathologies merit more aggressive

    Radionuclide angiography serves as a valuable adjunct in the noninvasive evaluation and monitoring of patients with valvular heart disease. Although estimations of regurgitant fractions and the differences between left and right ventricular stroke volumes can be made, the limitations of the techniques do not enable adequate quantitation of the severity of valvular insufficiency to warrant routine use in ambulatory management. The importance of radionuclide ventriculography, however, lies in its ability to examine global ventricular function both at rest and with exercise, thus enabling assessment of the functional reserve of the left and right ventricles. Such data are of considerable value in determining the need for invasive evaluation and the timing of valve replacement in patients with valvular heart disease. 41 references.

    2009-01-01

    Background The serotonin (5-HT) releasers (±)-fenfluramine and (+)-fenfluramine were withdrawn from clinical use due to increased risk of valvular heart disease. One prevailing hypothesis (i.e., the “5-HT hypothesis”) suggests that fenfluramine-induced increases in plasma 5-HT underlie the disease. Objective Here we critically evaluate the possible mechanisms responsible for fenfluramine-associated valve disease. Methods Findings from in vitro and in vivo experiments performed in our laboratory are reviewed. The data are integrated with existing literature to address the validity of the 5-HT hypothesis and suggest alternative explanations. Conclusions The overwhelming majority of evidence refutes the 5-HT hypothesis. A more likely cause of fenfluramine-induced valvulopathy is activation of 5-HT2B receptors on heart valves by the metabolite norfenfluramine. Future serotonergic medications should be designed to lack 5-HT2B agonist activity. PMID:19505264

Mean ESVs are 101.1 ml/m{sup 2} in AI + MI, 84.1 ml/m{sup 2} in AI, 66.5 ml/m{sup 2} in MI and 46.4 ml/m{sup 2} in MS respectively. 3. Mean EFs are 0.56 in AI + MI, 0.55 in AI, 0.57 in MI and 0.54 in MS respectively. 4. There are higher correlations between ESV and EF than between EDV and EF. 5. There are no significant correlation between EDP and EDV in all disease entities except AI, in which large EDV relatively correlates with high EDP. 6. In AI, EDV, ESV, EF and angiographic grade of regurgitation show close correlations between each other. 7. In MI with higher grade of regurgitation, ESV seems to be more sensitive indicator of left ventricular performance than EF. In MI with lower grade of regurgitation, EF seems to be more sensitive indicator of left ventricular performance than ESV. 8. In AI + MI, EDV, ESV and EDP show higher values than in any other disease involving single valve alone, but there are no correlations between ventricular volumes and grades of

    Aims Risk scores provide an important contribution to clinical decision-making, but their validity has been questioned in patients with valvular heart disease (VHD), since current scores have been mainly derived and validated in adults undergoing coronary bypass surgery. The Working Group on Valvular Heart Disease of the European Society of Cardiology reviewed the performance of currently available scores when applied to VHD, in order to guide clinical practice and future development of new scores. Methods and results The most widely used risk scores (EuroSCORE, STS, and Ambler score) were reviewed, analysing variables included and their predictive ability when applied to patients with VHD. These scores provide relatively good discrimination, i.e. a gross estimation of risk category, but cannot be used to estimate the exact operative mortality in an individual patient because of unsatisfactory calibration. Conclusion Current risk scores do not provide a reliable estimate of exact operative mortality in an individual patient with VHD. They should therefore be interpreted with caution and only used as part of an integrated approach, which incorporates other patient characteristics, the clinical context, and local outcome data. Future risk scores should include additional variables, such as cognitive and functional capacity and be prospectively validated in high-risk patients. Specific risk models should also be developed for newer interventions, such as transcatheter aortic valve implantation. PMID:21406443

    Cine MR Imaging was carried out using FLASH (fast low angle shot) which employes TE of 16 msec and TR of 30/similar to/40 msec. Regurgitant jet was visible as discrete area of low signal intensity extending from the incompetent valve into the respective cardiac chamber. In 20 patients with mitral regurgitation, the correlation of the length and area of mitral jet by cine MR and color doppler mapping was 0.74 and 0.71, respectively. Cine MR imaging is a promising modality for detection and quantification of valvular heart disease.

    Multislice computed tomography (MSCT) is a non-invasive, less expensive, low-radiation alternative to coronary angiography (CAG) prior to valvular heart surgery. MSCT has a high negative predictive value for coronary artery disease (CAD) but previous studies of patients with valvular disease have shown that MSCT, as the primary evaluation technique, lead to re-evaluation with CAG in about a third of cases and it is therefore not recommended. If a subgroup of patients with low- to intermediate risk of CAD could be identified and examined with MSCT, it could be cost-effective, reduce radiation and the risk of complications associated with CAG. The study cohort was derived from a national registry of patients undergoing CAG prior to valvular heart surgery. Using logistic regression, we identified significant risk factors for CAD and developed a risk score (CT-valve score). The score was validated on a similar cohort of patients from another registry. The study cohort consisted of 2221 patients, 521 (23.5%) had CAD. The validation cohort consisted of 2575 patients, 771 (29.9%) had CAD. The identified risk factors were male sex, age, smoking, hyperlipidemia, hypertension, aortic valve disease, extracardiac arteriopathy, ejection fraction <30% and diabetes mellitus. CT-valve score could identify a third of the population with a risk about 10%. A score based on risk factors of CAD can identify patients that might benefit from using MSCT as a gatekeeper to CAG prior to heart valve surgery. Copyright © 2016 Elsevier Ireland Ltd.

    Full Text Available Non-valvular heart disease is an important cause of cardiac disease in pregnancy and presents a unique challenge to the anesthesiologist during labor and delivery. A keen understanding of the underlying pathophysiology, in addition to the altered physiology of pregnancy, is the key to managing such patients. Disease-specific goals of management may help preserve the hemodynamic and ventilatory parameters within an acceptable limit and a successful conduct of labor and postpartum period

    Catheter-based treatment of valvular heart disease, such as transvalvular aortic valve replacement (TAVR) or mitral clip procedure, has been increasingly accepted as a treatment choice for the past several years. Such new treatment options have been changing the management of patients with valvular heart disease drastically while socio-economic factors regarding their application need to be taken into consideration. The use of echocardiography, including transesophageal echocardiography (TEE), for such catheter-based treatments is essential for the success of the procedures. Severe hypotension after TAVR is a life-threatening emergency. Rapid assessment and diagnosis in the catheterization or hybrid laboratory is essential for safety and a positive outcome. Possible diagnoses in this critical situation would include severe left ventricular dysfunction due to coronary obstruction, cardiac tamponade, aortic rupture, acute severe aortic and/or mitral valve regurgitation, and hypovolemia due to bleeding. Although new types of TAVR valves reduce para-valvular aortic regurgitation (AR) significantly, it is still important to judge the severity of para-valvular AR correctly in the laboratory. As for mitral clip procedure, TEE is vital for guiding and monitoring the entire process. Accurate identification of the location and the geometry of the regurgitant orifice is necessary for proper placement of the clip. Real-time 3D TEE provides helpful en face view of the mitral valve and clip together to this end. Residual mitral regurgitation (MR) after the first clip is not uncommon. Quick and precise imaging of the residual MR (location and severity) with TEE is extremely important for the interventionist to place the second clip and possibly third clip properly. After the completion of the clip procedure, mitral valve stenosis and also iatrogenic atrial septal defect need to be checked by TEE. Echocardiography, especially TEE, is also vital for the success of other newer trans

    The majority of evidence on the safety and efficacy of oral anticoagulation for stroke prevention amongst patients with atrial fibrillation is derived from those without significant valvular heart disease. This article will review current knowledge, areas of uncertainty and controversy, and ongoing research on oral anticoagulation for stroke prevention amongst patients with valvular heart disease. The rates of stroke, systemic embolism, and major bleeding were similar for patients with and without significant native valvular disease when treated with direct oral anticoagulants (DOACs) or vitamin K antagonists. There are very limited prospective data on the safety and efficacy of DOAC use for patients with bioprosthetic valves or rheumatic mitral stenosis. Atrial fibrillation patients with concomitant valvulopathies constitute a group with high thromboembolic risk and should be treated with oral anticoagulation. There is good supportive evidence that DOAC is well tolerated and effective in preventing thromboembolism amongst patients with native valvular disease. Further research is underway to better define the risks and benefits of DOAC use among patients with bioprosthetic valves or rheumatic mitral stenosis in preventing thromboembolic events. Until then, vitamin K antagonists remain the oral anticoagulant of choice for these patient subsets.

    Objective: To estimate the prevalence and the risk factors of preoperative coronary angiography (CAG) confirmed coronary stenosis in patients with degenerative valvular heart disease. Methods: A total of 491 patients who underwent screening CAG before valvular surgery due to degenerative valvular heart disease were enrolled from January 2011 to September 2014 in our hospital, and clinical data were analyzed. According to CAG results, patients were divided into positive CAG result (PCAG) group or negative CAG (NCAG) group. Positive CAG result was defined as stenosis ≥50% of the diameter of the left main coronary artery or stenosis ≥70% of the diameter of left anterior descending, left circumflex artery, and right coronary artery.Risk factors of positive CAG result were analyzed by multivariable logistic regression analysis, and Bootstrap method was used to verify the results. Results: There were 47(9.57%)degenerative valvular heart disease patients with PCAG. Patients were older ((68.0±7.6)years vs.(62.6±7.1)years, P valvular heart disease patients. Bootstrap method revealed satisfactory repeatability of multivariable logistic regression analysis results (age: OR =1.118, 95% CI 1.068-1.178, P =0.001; typical angina: OR =8.970, 95% CI 2.338-35.891, P =0.001; serum concentration of apolipoprotein B: OR =20.311, 95% CI 4.639-91.977, P =0.001). Conclusions: A low prevalence of PCAG before valvular surgery is observed in degenerative valvular heart disease patients in this patient cohort. Age, typical angina, and serum concentration of apolipoprotein B are independent risk factors of PCAG in this patient cohort.

    For clinical evaluation and decision-making in patients with valvular heart disease, the diagnostic armamentarium expands steadily. This evolution makes it difficult to choose the most appropriate approach for a specific valvular lesion. It may also reflect our uncertainty of what are the findings that best predict clinical outcome of patients, e. g. after surgery. Accordingly, for each type of valvular lesion, some pathophysiological considerations are stated in order to derive the most important measures that would allow optimal guidance of patients. Based on these considerations the value of an MR study is discussed for each valvular lesion. Newest advances in MR technology allow for highly accurate measurements of regurgitant volumes and hence, MR may be the method of choice for a quantitative evaluation of regurgitant valves. For assessment of stenosis severity, measurement of transvalvular pressure gradient is an appropriate measure and MR may not confer benefits over echocardiography, provided the ultrasound window is adequate (and stroke volume is in the normal range). With respect to surgical treatment, valvular morphology is of pivotal importance, particularly for the mitral valve, and echocardiography still appears to be the first line method. Little data relate lesion severity and/or morphology to clinical outcome. Conversely, the extent of cardiac adaptation to pressure- and/or volume-overload, i. e. ventricular remodeling, is a strong predictor of outcome, and is therefore most important for final judgement of the patient. For assessment of left and right ventricular remodeling, echocardiography typically provides all the necessary information. However, in special cases with discrepant findings, with inadequate ultrasound window, or in the preoperative work-up, MR may provide important information regarding cardiac adaptation to valvular lesion.

    Full Text Available Background: Valvular heart diseases (VHD are an important cause of morbidity and mortality worldwide and rheumatic fever still continues to be a contributing factor to VHD in the developing nations like India. This enormous disease burden often translates into huge economic and social losses. Aims: This study was undertaken to identify the sociodemographic characteristics of the patients with VHD, to find the frequency of different types of valvular diseases and their etiologies and the effect of such diseases on daily living. Materials and Methods: A hospital based observational study was carried out among the patients with VHD attending Cardiothoracic and Vascular Surgery OPD from April,2013 to Dec,2013.Data collection was done using a predesigned and pretested schedule after taking informed consent. Result; Out of the 108 patient’s majority were males and resided in rural areas. Their mean age was 36.39 ± 13.88. Mitral stenosis was found to be the commonest single valve lesion and most of the VHDs were of rheumatic origin. In 32.4% of the cases outdoor activities were completely restricted. Out of the 62 patients working outside, 40.2% were mostly absent from their workplace. Conclusion: Mitral stenosis of rheumatic origin was found to be the commonest type of valvular heart disease in this part. This study reveals that valvular heart disease of rheumatic origin still exists in our society. So preventive measures, diagnosis and management of valvular diseases should not be neglected and we need to provide preventive services in cases of rheumatic fever to reduce the development of VHD.

    The heart pump function was investigated by the methods of radionuclide kineventriculography, standart opaque ventryculography and echocardiography. The statistical analysis revealed lack of correlation for the ejection fraction, determined by the three methods. The methodological advantages of radionuclide kineventriculography are pointed out for exact and objective evaluation of the ejection fraction of the left cardiac ventricle, as well as some limitations in the application of this index in the clinical assessment of the heart pump function in patients, indicated for valvular prosthesis.

    For asymptomatic patients with moderate-severe valvular heart disease, in whom symptoms may be obscured, objective exercise tolerance measures are warranted for decisions concerning physical activities and surgical treatment. We compared 61 patients (39 with aortic stenosis, 22 with aortic or mitral regurgitation) to 23 controls without valvular heart disease but with indications for stress testing. All participants underwent cardiopulmonary function testing and dobutamine stress echocardiography. Blood was drawn before as well as after bicycle stress to assess high-sensitivity cardiac troponin T (hscTnT). Patients who underwent surgery were re-evaluated 1.5 ±0.9 years after the operation. Conventional bicycle test following guideline criteria revealed a pathologic result in 26% of the patients, whereas spiroergometry showed an objectively reduced exercise tolerance in 59%, reaching a prognostically relevant feature in 39%. Stress echocardiography detected a reduced systolic reserve in 33% and elevated filling pressures in 62%. These abnormalities were significantly less present in the control group (4, 17, 9, 9, 4% respectively, p valvular heart disease beyond stress-test criteria recommended in recent guidelines. High-sensitivity cardiac troponin I may be of additional value. Results of these tests presage post-operative function.

    We aimed to study the frequency, severity and predictors of valvular heart disease (VHD) in our lupus cohort. 211 patients were included. A transthoracic echocardiogram was used for this study. Significant valvular lesions were classified into two groups: valvular thickening and valvular dysfunction. Univariate logistic regression was performed in order to find associations with valvular thickening and dysfunction. Those variables with a p value ≤0.1 in the univariate analysis were subsequently included in multiple logistic regression models. Significant valve lesions were found in 53 patients (25%). The independent predictors of valvular thickening were the age at the time of the echocardiogram (OR 1.05, 95% CI 1.02-1.7), lymphopenia (OR 3.6, 95%CI 1.4-9.5), thrombocytopenia (OR 2.65, 95%CI 1.24-5.72), and anti-Sm antibodies (OR 3.28, 95%CI 1.44-7.33). The independent predictors of valvular dysfunction were age at the time of the echocardiogram (OR 1.045, 95%CI 1.009-1.083), thrombocytopenia (OR 5, 95%CI 1.66-14.86), hypertension (OR 6.2, 95%CI 2.1-18.4) and aPL (OR 6.2, 95%CI 2.1-18.4). Regarding the latter, the independent relation with valvular dysfunction was only seen for the double positivity aCL/LA, (OR 13.2, 95%CI 3.8-45.2, p<0.0001). Our study confirms the high prevalence of significant VHD in SLE patients. Clinical variables related with persistent inflammatory activity were associated with VHD. The association between VHD and aPL positivity was confirmed. Double-positive aCL/LA patients were most likely to suffer from valvular dysfunction. Copyright © 2016 Elsevier B.V.

    Physiologic changes during pregnancy can deteriorate or improve patients' hemodynamic status in the setting of valvular heart disease. There are sparse data regarding the effect of pregnancy on valve hemodynamics in normal pregnant women with known valvular heart disease. In a prospective study from July 2014 to January 2016, a total of 52 normal pregnant women who had mitral stenosis, aortic stenosis, or a history of mitral valve or aortic valve replacements were assessed. All patients underwent echocardiographic examinations and hemodynamic parameters were measured for both the mitral valve and aortic valve at first, second, and third trimesters. The parameters included mean gradient, peak gradient, mean gradient/heart rate, peak gradient/heart rate, pressure halftime, dimensionless velocity index, and valve area. Although most hemodynamic parameters (i.e., mean gradient, peak gradient, mean gradient/heart rate, and peak gradient/heart rate) increased approximately 50% from first to second trimester and first to third trimester (p 0.05). The ratio of changes between trimesters for valve area and dimensionless velocity index were comparable. No clinical decompensations were observed except for 3 and 7 cases of deterioration to functional class II at second and third trimesters, respectively. In conclusion, during a full-term and uncomplicated pregnancy, mitral and aortic valve gradients increase without significant changes in valve area that are more marked between the second and first trimester than between the third and second trimester.

    2013-08-01

    Concomitant coronary artery disease (CAD) and valvular heart disease is an increasingly common problem in the ageing population. Hybrid procedures combine surgical and transcatheter approaches to facilitate minimally invasive surgery or to transform a single high-risk open surgery into two less risky procedures. In ideal circumstances, this strategy may decrease the surgical risk in elderly, high-risk and reoperative surgical candidates, while improving patient comfort, convenience and cost-effectiveness. Hybrid procedures can be performed in a staged fashion or as a 'one-stop' procedure in a hybrid operating suite. Increasing evidence supports the safety and short-term efficacy of hybrid valve repair or replacement and coronary revascularisation procedures. Nevertheless, important questions remain, including the optimal timing of the individual procedures and the optimal antiplatelet therapy after percutaneous coronary intervention. With ongoing advances in procedural techniques and anticoagulation strategies, as well as the accumulation of long-term outcomes data, hybrid approaches to concomitant CAD and valvular heart disease will likely become increasingly common.

    The aim of this study was to evaluate the proportion of suspected heart failure patients with significant valvular heart disease. Early diagnosis of valve disease is essential as delay can limit treatment and negatively affect prognosis for undiagnosed patients. The prevalence of unsuspected valve disease in the community is uncertain. We prospectively evaluated 79 043 patients, between 2001 and 2011, who were referred to a community open access echocardiography service for suspected heart failure. All patients underwent a standard transthoracic echocardiogram according to British Society of Echocardiography guidelines. Of the total number, 29 682 patients (37.5%) were diagnosed with mild valve disease, 8983 patients (11.3%) had moderate valve disease and 2134 (2.7%) had severe valve disease. Of the total number of patients scanned, the prevalence of aortic stenosis, aortic regurgitation, mitral stenosis, mitral regurgitation was 10%, 8.4%, 1%, and 12.5% respectively. 18% had tricuspid regurgitation. 5% had disease involving one or more valves. Of patients with suspected heart failure in the primary care setting, a significant proportion have important valvular heart disease. These patients are at high risk of future cardiac events and will require onward referral for further evaluation. We recommend that readily available community echocardiography services should be provided for general practitioners as this will result in early detection of valve disease.

    Purpose: To determine the prevalence of valvular abnormalities after radiation therapy involving the heart region and/or treatment with anthracyclines and to identify associated risk factors in a large cohort of 5-year childhood cancer survivors (CCS). Methods and Materials: The study cohort consisted of all 626 eligible 5-year CCS diagnosed with childhood cancer in the Emma Children's Hospital/Academic Medical Center between 1966 and 1996 and treated with radiation therapy involving the heart region and/or anthracyclines. We determined the presence of valvular abnormalities according to echocardiograms. Physical radiation dose was converted into the equivalent dose in 2-Gy fractions (EQD 2 ). Using multivariable logistic regression analyses, we examined the associations between cancer treatment and valvular abnormalities. Results: We identified 225 mainly mild echocardiographic valvular abnormalities in 169 of 545 CCS (31%) with a cardiac assessment (median follow-up time, 14.9 years [range, 5.1-36.8 years]; median attained age 22.0 years [range, 7.0-49.7 years]). Twenty-four CCS (4.4%) had 31 moderate or higher-graded abnormalities. Most common abnormalities were tricuspid valve disorders (n=119; 21.8%) and mitral valve disorders (n=73; 13.4%). The risk of valvular abnormalities was associated with increasing radiation dose (using EQD 2 ) involving the heart region (odds ratio 1.33 per 10 Gy) and the presence of congenital heart disease (odds ratio 3.43). We found no statistically significant evidence that anthracyclines increase the risk. Conclusions: Almost one-third of CCS treated with potentially cardiotoxic therapy had 1 or more asymptomatic, mostly mild valvular abnormalities after a median follow-up of nearly 15 years. The most important risk factors are higher EQD 2 to the heart region and congenital heart disease. Studies with longer follow-up are necessary to investigate the clinical course of asymptomatic valvular abnormalities in CCS

    to analyze the sociodemographic and clinical characteristics of patients with valvular heart disease and to verify the influence of these variables on the impact of valve disease in daily life. the study involved 86 outpatients. Data collection was performed in two stages - face-to-face interview for sociodemographic and clinical characterization and through telephone contact for the application of the Instrument to Measure the Impact of Valvular Heart Disease on Patient's Everyday Life (IDCV). Data were analyzed through descriptive statistics and multiple regression analysis. it was noticed that the total score of IDCV and its domains were influenced by age, schooling, presence or absence of symptoms, use or not of diuretic. The impact of the disease was influenced by sociodemographic and clinical variables. The results provide subsidies for the design of nursing interventions aimed at reducing the impact of the disease on the patient's daily life with valve disease.

  20. X-ray picture of the heart turn in echocardiographic diagnosis of rheumatic heart disease

    The paper is concerned with X-ray and echocardiographic investigation of the heart in 461 patients with mitral-tricuspidal disease. In 377 (82%) cases a turn of the heart along the longitudinal axis (counter clockwise) to the left and back was revealed. X-ray recognition of the heart turn made it possible to set an echocardiographic sensor to spot some of the cardiac cavities, interventricular septum and valvular apparatus. The correct setting of the echocardiographic sensor resulted in the determination of true sizes of each cardiac cavity, diagnosis of the nature of each valvular lesion and the recognition of such complications of rheumatic heart diseases as valvular calcinosis, left atrial thrombosis and disorder of myocardial contractility

    The 2014 American College of Cardiology/American Heart Association guidelines for valvular heart disease were released to help guide the clinician in caring for patients with this ever more prevalent and complex group of diseases and have been instrumental in providing a foundation of knowledge for the management of patients with valvular heart disease. However, there are many caveats in applying the guidelines to individual patients. As clinicians, we wish to outline important aspects to be considered by other clinicians, including the integration of the echocardiogram with the history and physical examination, recognition of discordant data within an echocardiographic examination, and proper interpretation of the cutoff measurements applied to timing of intervention. Decisions regarding management should be individualized to the institution, particularly when recommending early operation for an asymptomatic patient. Finally, all decisions should be individualized to each patient by not only recognizing specific comorbidities, but also understanding the patient's needs and preferences.

    For clinical evaluation and decision-making in patients with valvular heart disease, the diagnostic armamentarium expands steadily. This evolution makes it difficult to choose the most appropriate approach for a specific valvular lesion. It may also reflect our uncertainty of what are the findings that best predict clinical outcome of patients, e. g. after surgery. Accordingly, for each type of valvular lesion, some pathophysiological considerations are stated in order to derive the most important measures that would allow optimal guidance of patients. Based on these considerations the value of an MR study is discussed for each valvular lesion. Newest advances in MR technology allow for highly accurate measurements of regurgitant volumes and hence, MR may be the method of choice for a quantitative evaluation of regurgitant valves. For assessment of stenosis severity, measurement of transvalvular pressure gradient is an appropriate measure and MR may not confer benefits over echocardiography, provided the ultrasound window is adequate (and stroke volume is in the normal range). With respect to surgical treatment, valvular morphology is of pivotal importance, particularly for the mitral valve, and echocardiography still appears to be the first line method. Little data relate lesion severity and/or morphology to clinical outcome. Conversely, the extent of cardiac adaptation to pressure- and/or volume-overload, i. e. ventricular remodeling, is a strong predictor of outcome, and is therefore most important for final judgement of the patient. For assessment of left and right ventricular remodeling, echocardiography typically provides all the necessary information. However, in special cases with discrepant findings, with inadequate ultrasound window, or in the preoperative work-up, MR may provide important information regarding cardiac adaptation to valvular lesion.

    Full Text Available Patients with valvular heart disease and suffering atrial fibrillation of more than 12 months duration have a low probability of remaining in sinus rhythm after valve surgery alone. We performed intra-operative radiofrequency ablation or cryoablation as an alternative to surgical maze ІІІ procedure to create linear lesion lines for conversion of this arrhythmia to sinus rhythm. A total of 30 patients with valvular heart disease and chronic persistent atrial fibrillation underwent different combinations of valve surgery and concomitant maze procedure with radiofrequency or cryo probes. These patients aged 48.10 ± 9.84 years in radiofrequency ablation group and 51.10 ± 13.93 years in cryoablation group. Both atrial ablation with radiofrequency probes, needed 26.15 ± 3.67 min extra ischemic time and ablation by mean of cryo-probes needed an extra ischemic time of 29.62 ± 4.27 min. There was one in hospital death postoperatively because of respiratory failure but no other complication. 6 months after the operation, among 30 patients with both atrial ablations, 25 patients were in sinus rhythm, no patient had junctional rhythm and 5 patients had persistent atrial fibrillation. At 12 months follow up, freedom from atrial fibrillation was 85% in radiofrequency group and 80% in cryo group. Doppler echocardiography in these patients demonstrated atrial contractility in 70% of the patients. Intraoperative radiofrequency or cryo-ablation of both atriums are effective and less invasive alternatives for the original maze procedure to eliminate the atrial fibrillation, and can be done in patients with valvular heart disease without increasing the risk of operation.

  4. Role of modern 3D echocardiography in valvular heart disease

    Science.gov (United States)

    2014-01-01

    Three-dimensional (3D) echocardiography has been conceived as one of the most promising methods for the diagnosis of valvular heart disease, and recently has become an integral clinical tool thanks to the development of high quality real-time transesophageal echocardiography (TEE). In particular, for mitral valve diseases, this new approach has proven to be the most unique, powerful, and convincing method for understanding the complicated anatomy of the mitral valve and its dynamism. The method has been useful for surgical management, including robotic mitral valve repair. Moreover, this method has become indispensable for nonsurgical mitral procedures such as edge to edge mitral repair and transcatheter closure of paravaluvular leaks. In addition, color Doppler 3D echo has been valuable to identify the location of the regurgitant orifice and the severity of the mitral regurgitation. For aortic and tricuspid valve diseases, this method may not be quite as valuable as for the mitral valve. However, the necessity of 3D echo is recognized for certain situations even for these valves, such as for evaluating the aortic annulus for transcatheter aortic valve implantation. It is now clear that this method, especially with the continued development of real-time 3D TEE technology, will enhance the diagnosis and management of patients with these valvular heart diseases.

    With improving reproductive assistive technologies, advancing maternal age, and improved survival of patients with congenital heart disease, valvular heart disease has become an important cause of morbidity and mortality in pregnant women. In general, stenotic lesions, even those in the moderate range, are poorly tolerated in the face of hemodynamic changes of pregnancy. Regurgitant lesions, however, fare better due to the physiologic afterload reduction that occurs. Intervention on regurgitant valve preconception follows the same principles as a non-pregnant population. Prosthetic valves in pregnancy are increasingly commonplace, presenting new management challenges including valve deterioration and valve thrombosis. In particular, anticoagulation during pregnancy is challenging. Pregnancy is a hypercoagulable state and the risks of maternal bleeding and fetal anticoagulant risks need to be balanced. Maternal mortality and complications are lowest with warfarin use throughout pregnancy; however, fetal outcomes are best with low molecular weight heparin use. ACC/AHA guidelines recommend warfarin use, even in the first trimester, if doses are less than 5 mg/day; however, adverse fetal events are not zero at this dose. In addition, it is unclear if better monitoring of low molecular weight heparin with peak and trough anti-Xa levels would lower maternal risks as this has been inconsistently monitored in reported studies. Fortunately, with the emergence of newer data, our understanding of anticoagulant strategies in pregnancy is improving over time which should translate to better pregnancy outcomes in this higher risk population.

    To determine the effect of secondary penicillin prophylaxis on echocardiographic diagnosed valvular changes in patients with rheumatic heart disease or history of acute rheumatic fever in the Townsville Health district. Patients with known were identified from the North Queensland register, serial echocardiogram results and number of secondary penicillin prophylaxis doses received in 2014 were collated. Descriptive statistics were utilised. Townsville Hospital and outreach clinics within the Townsville Health catchment zone. All patients diagnosed with acute rheumatic fever or rheumatic heart disease between 2010 and October 2013 who had serial echocardiograms prior to and post commencement of secondary penicillin prophylaxis were included. All patients were of Aboriginal or Torres Strait Islander descent. Progression of echocardiographic valvular changes and association with secondary penicillin prophylaxis compliance. Compliance with secondary penicillin prophylaxis among the study population was a secondary outcome measure. Twenty-three patients were recruited. Only those patients who were compliant with secondary penicillin prophylaxis had any improvement in valvular changes on echocardiogram. Four of six patients without any baseline valvular involvement developed new valvular changes. Seventy percent of patients received >75% of secondary penicillin prophylaxis doses. This small study of patients in Townsville suggests that with good secondary penicillin prophylaxis compliance there is regression of some cardiac lesions over time in people with rheumatic heart disease. Furthermore the natural history of acute rheumatic fever in the Indigenous population is progressive requiring strict adherence to secondary penicillin prophylaxis. Prospective studies or use of data from the nationwide RHD register and standardised reporting of cardiac echocardiograms will provide more robust evidence. © 2017 National Rural Health Alliance Inc.

    Atrial fibrillation (AF) is a major worldwide public health problem, and AF in association with valvular heart disease (VHD) is also common. However, management strategies for this group of patients have been less informed by randomized trials, which have largely focused on 'non-valvular AF' patients. Thrombo-embolic risk also varies according to valve lesion and may also be associated with CHA2DS2VASc score risk factor components, rather than only the valve disease being causal. Given marked heterogeneity in the definition of valvular and non-valvular AF and variable management strategies, including non-vitamin K antagonist oral anticoagulants (NOACs) in patients with VHD other than prosthetic heart valves or haemodynamically significant mitral valve disease, there is a need to provide expert recommendations for professionals participating in the care of patients presenting with AF and associated VHD. To address this topic, a Task Force was convened by the European Heart Rhythm Association (EHRA) and European Society of Cardiology (ESC) Working Group on Thrombosis, with representation from the ESC Working Group on Valvular Heart Disease, Heart Rhythm Society (HRS), Asia Pacific Heart Rhythm Society (APHRS), South African Heart (SA Heart) Association and Sociedad Latinoamericana de Estimulación Cardíaca y Electrofisiología (SOLEACE) with the remit to comprehensively review the published evidence, and to publish a joint consensus document on the management of patients with AF and associated VHD, with up-to-date consensus recommendations for clinical practice for different forms of VHD. This consensus document proposes that the term 'valvular AF' is outdated and given that any definition ultimately relates to the evaluated practical use of oral anticoagulation (OAC) type, we propose a functional Evaluated Heartvalves, Rheumatic or Artificial (EHRA) categorization in relation to the type of OAC use in patients with AF, as follows: (i) EHRA Type 1 VHD, which refers

  8. The Role of Stress Echocardiography in Valvular Heart Disease: A Current Appraisal.

    Stress echocardiography is a widely available, safe, low-cost, versatile imaging modality which is becoming increasingly recognized as a valuable tool in the assessment of patients with native and prosthetic left-sided valvular heart disease. It provides a quantitative assessment to help guide clinical decision-making when discordance exists between symptoms and severity of valve disease. Exercise (treadmill or bicycle) remains the preferred stress modality, but pharmacological augmentation with dobutamine can be used if needed. Low-dose dobutamine stress echocardiography is specifically valuable in patients with low-flow, low-gradient aortic stenosis when attempting to differentiate true severe aortic stenosis from pseudo-severe aortic stenosis. Stress echocardiography not only identifies high-risk features that indicate need for earlier surgery, it also provides useful information for the peri- and postoperative period, including long-term outcome, risk stratification to guide monitoring frequency, and offers guidance for eligibility in competitive sports participation. As research continues to expand the utility of stress echocardiography in the management of patients with valvular heart disease, future research should focus on the recognition of newer parameters identifying high-risk features including subsequent validation in a large population. © 2017 S.

    The objective was to investigate the risk of valvular heart disease in humans in relation to the use of selective serotonin reuptake inhibitors (SSRIs) and serotonin and noradrenaline reuptake inhibitors. A case-control study. We conducted a case-control study within this cohort in which patients with newly diagnosed cardiac valve regurgitation were age-matched to controls. Patient demographics, their cardiovascular risk factors and medication use were extracted in both series. Use of SSRIs, serotonin and noradreline reuptake inhibitors (SNRIs) and other pro-serotonergic agents, their dose and treatment duration were recorded. Logistic regression analysis was used to establish the strength of the association between SSRI/SNRI use and valvular heart disease. Outpatient clinic of the cardiology department at the Ghent University Hospital, East-Flanders in Belgium. Total of 2911 persons 21-58 years of age who had undergone an echocardiogram in the period 2006-2010 and had no known cardiovascular disease or previous cardiac intervention. Two hundred and six echocardiographically proven cases of valvular regurgitation and 195 matched controls. Odd ratio of valvular disease associated with intake of serotonergic drugs. Of the 206 patients with newly diagnosed cardiac valve regurgitation, 11.6% were exposed to serotonergic agents compared to 4.1% in the 195 control patients, leading to an odds ratio of 3.08 (95% confidence interval [CI] 1.35-7.04). The analysis of doses and treatment durations revealed a dose-relationship pattern between SSRI/SNRI use and prevalent valvular heart disease. In this study, use of serotonergic antidepressants was associated with an increased rate of valvular regurgitation in humans.

    One of the reasons why use of Doppler echocardiography is growing rapidly is because of its utility in detecting the presence of valvular stenosis and in estimating its severity. Detection of the presence of stenotic valvular heart disease using Doppler echocardiography was originally described over 10 years ago. It has been demonstrated that Doppler blood velocity data could be used to estimate the severity of a stenotic lesion. This chapter discusses the evaluation of valvular stenois using Doppler

    Stress echocardiography is recommended for the assessment of asymptomatic patients with severe valvular heart disease (VHD) when there is discrepancy between symptoms and resting markers of severity. The aim of this study is to determine the prognostic value of exercise stress echocardiography in patients with common valve lesions. One hundred and fifteen patients with VHD (aortic stenosis (n=28); aortic regurgitation (n=35); mitral regurgitation, (n=26); mitral stenosis (n=26)), and age- and sex-matched controls (n=39) with normal ejection fraction underwent exercise stress echocardiography. The primary endpoint was a composite of death or hospitalization for heart failure. Asymptomatic VHD patients had lower exercise capacity than controls and 37% of patients achieved 60 mmHg) was associated with an increased risk of death or hospital admission (14% vs 1%, P<0.0001). The assessment of contractile reserve did not offer additional predictive value. In conclusion, an abnormal stress echocardiogram is associated with death and hospitalization with heart failure at 2 years. Stress echocardiography should be considered as part of the routine follow-up of all asymptomatic patients with VHD.

    Full Text Available Objective: To analyze the results of surgical correction of patients with tricuspid pathology in rheumatic multi-valvular heart disease. Methods: We retrospectively analyzed outcomes of surgical correction of tricuspid valve disease in 292 patients with rheumatic multi-valvular heart defects, who underwent surgery in our clinic. Results: The age of our patients ranged from 12 to 74 years (mean age 36.7 (9.4 years, among them 197 (67.4% women and 95 (32.6% - men. According to the degree of circulatory disorders, 21 (7.2% patients were in NYHA class III and 271 (92.8% patients - class IV. Of them 235 (80.5% patients were operated by the method of De Vega using plastic fibrous ring. After tricuspid valve (TV and fibrous ring repair in 26.9% - tricuspid regurgitation disappeared, in 62.8% - regurgitation decreased to the 1st degree, and the remaining 10.3% of patients had 2nd (moderate degree tricuspid regurgitation. In 7 (2.38% cases of infective endocarditis, the "open heart surgery" correction – replacement of TV with biological prosthesis was made. Creation of the bicuspid tricuspid valve techniques was used in 13.4% of cases. Conclusion: Our study demonstrated that correction of tricuspid valve disease in our cohort of patients, including valve repair and replacement and reconstructive surgery of fibrous ring alone or in combination with mitral or aortic valve replacement/ repair is accompanied by reduction of tricuspid regurgitation and reduction of cardiac chamber size and right ventricular pressure. No complications intrinsic to operative technique of tricuspid valve reconstructive surgery as advanced atrioventricular block or myocardial ischemia and infarction were recorded.

    2013-12-01

    In 2012 the new and collaborative "Guidelines on the management of valvular heart disease (version 2012)" were published by the European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS). These guidelines emphasize that decision-making in patients with valvular heart disease should ideally be carried out by a"heart team" with particular expertise in valvular heart disease. In aortic regurgitation pathologies of the aortic root are frequent and in patients with Marfan syndrome, surgery is indicated when the maximal ascending aortic diameter is ≥50 mm, while the threshold for intervention should be lower in patients with risk factors for progression. Regarding aortic stenosis, transcatheter aortic valve implantation (TAVI) should be performed only in hospitals with on-site cardiac surgery and with a"heart team" available to assess patient risks. The TAVI procedure is indicated in patients with severe symptomatic aortic stenosis who are judged by the"heart team" to be unsuitable for surgery but have sufficient life expectancy. It should be considered for high-risk patients with severe symptomatic aortic stenosis based on the individual risk profile assessed by the"heart team". Furthermore, low flow - low gradient aortic stenosis with normal ejection fraction and the difficult topic of asymptomatic severe aortic stenosis and the indications for aortic valve replacement are discussed. With respect to mitral regurgitation, valve repair should be the preferred technique when it is expected to be durable. The topics of asymptomatic mitral regurgitation as well as percutaneous mitral valve repair using the edge to edge technique as an alternative for high risk patients are discussed. Tricuspid disease should not be forgotten and during left-sided valve surgery, tricuspid valve surgery should be considered in the presence of mild to moderate secondary regurgitation if there is significant annular dilatation.

    Abstract Empirical evidence regarding the association between antidepressants and valvular heart disease (VHD) is scarce. Using Taiwan's National Health Insurance Research database, this nested case-control study assessed the association between antidepressants and VHD in a Chinese population. Among a cohort of patients who used at least 3 prescription antidepressants, 874 cases with VHD and 3496 matched controls (1:4 ratio) were identified. Conditional logistic regression models were used to examine the timing, duration, dose and type of antidepressants use, and the risk of VHD. Current use of antidepressants was associated with a 1.4-fold increase in the risk of VHD (adjusted odds ratio [aOR] 1.44; 95% confidence interval [CI] 1.17–1.77). Among current users, a dose–response association was observed in terms of the cumulative duration and the cumulative antidepressant dose. Significantly higher risks of VHD were observed among the current users of tricyclic antidepressants (aOR 1.40 [1.05–1.87]). We found that the use of antidepressants was associated with a greater risk of VHD and that the risks varied according to different antidepressants. PMID:27057841

    The current state-of-the-art in radionuclide imaging of valvular heart disease is based on different angiographic patterns in three left-sided valve abnormalities: pressure overload, volume overload, and inflow obstruction. In pressure overload, the left ventricle has normal dimensions or is minimally dilated the volume overload involves a left ventricular dilatation with a normal or reduced ejection fraction at rest the left ventricular function in inflow obstruction is normal, but in some cases may be depressed. Radionuclide angiography evaluates the effect of a valve abnormality on cardiac chamber and function thallium-201 imaging diagnoses regional myocardial blood flow and cell integrity and can evaluate the associated coronary artery disease.

    Although ischemic heart disease remains the leading cause of cardiac-related morbidity and mortality in the industrialized countries, a growing number of mainly elderly patients will experience a problem of valvular heart disease (VHD), often requiring surgical intervention at some stage. Doppler-echocardiography is the most popular imaging modality used in the evaluation of this disease entity. It encompasses, however, some non-negligible constraints which may hamper the quality and thus the interpretation of the exam. Cardiac catheterization has been considered for a long time the reference technique in this field, however, this technique is invasive and considered far from optimal. Cardiovascular magnetic resonance imaging (MRI) is already considered an established diagnostic method for studying ventricular dimensions, function and mass. With improvement of MRI soft- and hardware, the assessment of cardiac valve function has also turned out to be fast, accurate and reproducible. This review focuses on the usefulness of MRI in the diagnosis and management of VHD, pointing out its added value in comparison with more conventional diagnostic means. (orig.)

    Apixaban is approved for the prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation. However, the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) trial included a substantial number of patients with valvular heart disease and only excluded patients with clinically significant mitral stenosis or mechanical prosthetic heart valves. We compared the effect of apixaban and warfarin on rates of stroke or systemic embolism, major bleeding, and death in patients with and without moderate or severe valvular heart disease using Cox proportional hazards modeling. Of the 18 201 patients enrolled in ARISTOTLE, 4808 (26.4%) had a history of moderate or severe valvular heart disease or previous valve surgery. Patients with valvular heart disease had higher rates of stroke or systemic embolism and bleeding than patients without valvular heart disease. There was no evidence of a differential effect of apixaban over warfarin in patients with and without valvular heart disease in reducing stroke and systemic embolism (hazard ratio [HR], 0.70; 95% confidence interval [CI], 0.51-0.97 and HR, 0.84; 95%, CI 0.67-1.04; interaction P=0.38), causing less major bleeding (HR, 0.79; 95% CI, 0.61-1.04 and HR, 0.65; 95% CI, 0.55-0.77; interaction P=0.23), and reducing mortality (HR, 1.01; 95% CI, 0.84-1.22 and HR, 0.84; 95% CI, 0.73-0.96; interaction P=0.10). More than a quarter of the patients in ARISTOTLE with nonvalvular atrial fibrillation had moderate or severe valvular heart disease. There was no evidence of a differential effect of apixaban over warfarin in reducing stroke or systemic embolism, causing less bleeding, and reducing death in patients with and without valvular heart disease.

    The influence of underlying heart disease or presence of atrial fibrillation (AF) on atrial excitation during sinus rhythm (SR) is unknown. We investigated atrial activation patterns and total activation times of the entire atrial epicardial surface during SR in patients with ischemic and/or valvular heart disease with or without AF. Intraoperative epicardial mapping (N=128/192 electrodes, interelectrode distances: 2 mm) of the right atrium, Bachmann's bundle (BB), left atrioventricular groove, and pulmonary vein area was performed during SR in 253 patients (186 male [74%], age 66±11 years) with ischemic heart disease (N=132, 52%) or ischemic valvular heart disease (N=121, 48%). As expected, SR origin was located at the superior intercaval region of the right atrium in 232 patients (92%). BB activation occurred via 1 wavefront from right-to-left (N=163, 64%), from the central part (N=18, 7%), or via multiple wavefronts (N=72, 28%). Left atrioventricular groove activation occurred via (1) BB: N=108, 43%; (2) pulmonary vein area: N=9, 3%; or (3) BB and pulmonary vein area: N=136, 54%; depending on which route had the shortest interatrial conduction time ( P <0.001). Ischemic valvular heart disease patients more often had central BB activation and left atrioventricular groove activation via pulmonary vein area compared with ischemic heart disease patients (N=16 [13%] versus N=2 [2%]; P =0.009 and N=86 [71%] versus N=59 [45%]; P <0.001, respectively). Total activation times were longer in patients with AF (AF: 136±20 [92-186] ms; no AF: 114±17 [74-156] ms; P <0.001), because of prolongation of right atrium ( P =0.018) and BB conduction times ( P <0.001). Atrial excitation during SR is affected by underlying heart disease and AF, resulting in alternative routes for BB and left atrioventricular groove activation and prolongation of total activation times. Knowledge of atrial excitation patterns during SR and its electropathological variations, as demonstrated in

    In the United States, the octogenarian population is projected to triple by 2050. With this aging population, the prevalence of valvular heart disease (VHD) is on the rise. The etiology, approach to treatment, and expected outcomes of VHD are different in the elderly compared with younger patients. Both stenotic and regurgitant lesions are associated with unfavorable outcomes if left untreated. Surgical mortality remains high due to multiple co-morbidities, and long-term survival benefit is dependent on many variables including valvular pathology. Quality of life is an important consideration in treatment decisions in this age group. Increasingly, octogenarian patients are receiving transcatheter therapies, with transcatheter aortic valve replacement having the greatest momentum. Numerous transcatheter devices for management of other valve lesions are currently in early clinical trials. This review will describe the epidemiology, etiology, diagnosis, and therapeutic options for VHD in the oldest old, with a focus on transcatheter technologies.

    Valvular heart disease has been a significant cause of heart disease worldwide. In Ethiopia, it particularly affects young individuals and constitutes the major cause of cardiovascular disease. Factors associated with choice of treatment for advanced valvular heart disease are variable. The objective of this study is to review surgery done for Ethiopian patients with valvular heart disease. We analyzed data on patients who had valve surgery and follow-up at the Tikur Anbessa Specialized Hospital cardiology unit. We collected data on sociodemographic characteristics, the pre-operative status of effected valves and co-morbidities, and assessed their associations with patient management options. A total of 157 valve surgeries were done from 1983 to 2013. Mean age at time of surgery was 26.7 years and females constituted 66% of the cases. Patients with rheumatic heart disease were younger, more likely to be female and have atrial fibrillation, but less likely to have impaired left ventricular systolic function when compared to patients with non-rheumatic heart disease. More than 75% of the surgical procedures done were mechanical valve replacement. Mechanical valves, compared with bioprosthetic valves, were more likely to be used in patients with rheumatic heart disease. The median age of those receiving mechanical valves, 24 (IQR 22-28) years, was lower than those receiving bioprosthetic valves, 31.5 (IQR 29.9-37.9) years. Mechanical valve replacement was significantly higher in those under the age of 20 years (Adjusted Odds Ratio 41.0, 95% CI: 3.0-557.2) and in those between 20 and 29 years of age (Adjusted Odds Ratio 14.3, 95% CI: 2.3-88.6). Valve surgery for valvular heart diseases has been more common performed for young and female patients. A great majority of the replacements done have been with mechanical valves. As many of the patients have been younger and female, the choice of valve surgery and the need for anticoagulation impacts subsequent management of

    Management strategies for patients with atrial fibrillation (AF) in association with valvular heart disease (VHD) have been less informed by randomized trials, which have largely focused on ‘non-valvular AF’ patients. Thromboembolic risk also varies according to valve lesion and may also be associated with CHA2DS2-VASc score risk factor components, rather than only the valve disease being causal. Given the need to provide expert recommendations for professionals participating in the care of patients presenting with AF and associated VHD, a task force was convened by the European Heart Rhythm Association (EHRA) and European Society of Cardiology (ESC) Working Group (WG) on Thrombosis, with representation from the ESC WG on Valvular Heart Disease, Heart Rhythm Society (HRS), Asia Pacific Heart Rhythm Society (APHRS), South African Heart (SA Heart) Association and Sociedad Latinoamericana de Estimulación Cardíaca y Electrofisiología (SOLEACE) with the remit to comprehensively review the published evidence, and to produce a consensus document on the management of patients with AF and associated VHD, with up-to-date consensus statements for clinical practice for different forms of VHD, based on the principles of evidence-based medicine. This is an executive summary of a consensus document which proposes that the term ‘valvular AF’ is outdated and given that any definition ultimately relates to the evaluated practical use of oral anticoagulation (OAC) type, we propose a functional EHRA (Evaluated Heartvalves, Rheumatic or Artificial) categorization in relation to the type of OAC use in patients with AF, as follows: (1) EHRA (Evaluated Heartvalves, Rheumatic or Artificial) type 1 VHD, which refers to AF patients with ‘VHD needing therapy with a vitamin K antagonist (VKA)’ and (2) EHRA (Evaluated Heartvalves, Rheumatic or Artificial) type 2 VHD, which refers to AF patients with ‘VHD needing therapy with a VKA or a non-VKA oral anticoagulant also taking

    Radionuclide angiocardiography provides a noninvasive assessment of cardiac function and blood flow through the heart and lungs. During the past three years, this procedure has been used at the Duke University Medical Center for evaluation of 343 patients with congenital heart disorders. A review of this experience shows tat the resulting data were frequently useful in the surgical management of these patients. In patients with abnormal blood flow patterns, noninvasive imaging of blood flow was useful before and after operative correction. Radionuclide measurements of left-to-right intracardiac shunts were sufficiently accurate for use in the initial evaluation of patients with murmurs and to document the absence of shunt after operative closure of intracardiac septal defects. Moreover, measurements of right-to-left cardiac shunts were of benefit in the management of children with cyanotic heart disease. Measurements of left ventricular function obtained during rest and exercise were most useful in patients with origin of the left coronary artery from the pulmonary artery and in patients with congenital valvular insufficiency. This experience demonstrates that radionuclide angiocardiography provides important measurements of central hemodynamics and cardiac function which are useful in the management of patients with congenital heart disorders

    We examined the prognostic value of stress echocardiography appropriateness criteria for evaluation of valvular heart disease in 100 consecutive patients. Of the studies, 49%, 36%, and 15% were classified as appropriate, uncertain, and inappropriate, respectively. Over a median of 12.6 months, 24 events (12 deaths and 12 heart failure admissions) occurred. The 12-month event-free survival was significantly reduced in patients with appropriate or uncertain studies compared with patients with inappropriate studies (p = 0.04 and p = 0.005, respectively). There was no survival difference between patients with an appropriate or uncertain indication (p = 0.1). The only independent predictors of events were a positive stress echocardiogram (hazard ratio: 15.5, p valvular heart disease provide the ability to differentiate between patients at high- (appropriate group) and low- (inappropriate group) risk of cardiac events. Reclassification of the uncertain group may improve the differential value of these criteria. Copyright © 2013 American College of Cardiology Foundation. Published by Elsevier Inc.

    To evaluate the clinical and epidemiological profile of patients with valvular heart disease who arrived decompensated at the emergency department of a university hospital in Brazil. A descriptive analysis of clinical and echocardiographic data of 174 patients with severe valvular disease, who were clinically decompensated and went to the emergency department of a tertiary cardiology hospital, in the State of São Paulo, in 2009. The mean age of participants was 56±17 years and 54% were female. The main cause of valve disease was rheumatic in 60%, followed by 15% of degenerative aortic disease and mitral valve prolapse in 13%. Mitral regurgitation (27.5%) was the most common isolated valve disease, followed by aortic stenosis (23%), aortic regurgitation (13%) and mitral stenosis (11%). In echocardiographic data, the mean left atrial diameter was 48±12mm, 38±12mm for the left ventricular systolic diameter, and 54±12mm for the diastolic diameter; the mean ejection fraction was 56±13%, and the mean pulmonary artery pressure was 53±16mmHg. Approximately half of patients (44%) presented atrial fibrillation, and over one third of them (37%) had already undergone another cardiac surgery. Despite increased comorbidities and age-dependent risk factors commonly described in patients with valvular heart disease, the clinical profile of patients arriving at the emergency department represented a cohort of rheumatic patients in more advanced stages of disease. These patients require priority care in high complexity specialized hospitals.

    Transcatheter aortic valve implantation (TAVI) and transcatheter mitral valve repair (TMVR) are increasingly used for managing patients with valvular heart disease to whom surgery presents a high-risk. As these are costly procedures, a systematic review of studies concerned with their economic assessment was undertaken. The search was performed in PubMed and the Cochrane Library and followed recommended methodological steps. Studies were screened and their data were retrieved and were synthesized using a narrative approach. Twenty-four, good to high quality, evaluations were identified, representing different viewpoints, modelling techniques and willingness-to-pay thresholds. Studies show that in high-risk patients with symptomatic aortic stenosis, TAVI may be cost-effective compared with medical management (MM) across many health care settings. In contrast, studies of TAVI compared with surgical aortic valve replacement (SAVR) yield conflicting and inconclusive results. The limited data available show that TMVR may also be cost-effective relative to MM in mitral valve disease. Existing evidence indicates that transcatheter techniques may be cost-effective options, relative to MM, in high-risk patients with valvular disease. Nonetheless, more research is needed to establish their economic value further, to investigate the drives of cost-effectiveness, and to evaluate surgical with transcatheter techniques in aortic valvular disease.

    Blood-based biomarkers have been extensively studied in a range of cardiovascular diseases and have established utility in routine clinical care, most notably in the diagnosis of acute coronary syndrome (e.g., troponin) and the management of heart failure (e.g., brain-natriuretic peptide). The role of biomarkers is less well established in the management of valvular heart disease (VHD), in which the optimal timing of surgical intervention is often challenging. One promising biomarker that has been the subject of a number of recent VHD research studies is high sensitivity troponin (hs-cTn). Novel high-sensitivity assays can detect subclinical myocardial damage in asymptomatic individuals. Thus, hs-cTn may have utility in the assessment of asymptomatic patients with severe VHD who do not have a clear traditional indication for surgical intervention. In this state-of-the-art review, we examine the current evidence for hs-cTn as a potential biomarker in the most commonly encountered VHD conditions, aortic stenosis and mitral regurgitation. This review provides a synopsis of early evidence indicating that hs-cTn has promise as a biomarker in VHD. However, the impact of its measurement on clinical practice and VHD outcomes needs to be further assessed in prospective studies before routine clinical use becomes a reality.

    Valvular cardiomyopathy can present a diagnostic challenge in the absence of overt cardiac symptoms. This report describes the case of a 46-year-old woman who presented with acute peritonitis associated with vomiting and abdominal distension. Subsequent abdominal computed tomography and ultrasound revealed bibasal pleural effusions, ascites, and normal ovaries. An echocardiogram revealed that all cardiac chambers were dilated with a global decrease in contractility and severe mitral, tricuspid, and aortic regurgitation. A diagnosis of cardiomyopathy with acute heart failure, secondary to valvular heart disease, was secured. Acute peritonitis as the presenting feature of valvular cardiomyopathy is a rare clinical entity.

    201 Tl myocardial SPECT was performed in cases of dilated cardiomyopathy and valvular heart disease with left ventricular eccentric hypertrophy, and the two groups were compared from the standpoint of the mechanism of onset of myocardial disorders. Significant coefficients of correlation were seen between the Tl score and LVDd (r=0.792, r=0.785) and Tl score and LVEF (r=-0.634, r=-0.555) in both dilated cardiomyopathy and valvular heart disease. In cases of valvular heart disease, significant correlation coefficients (r=-0.756, r=-0.720) between LVDd and r-WR (relative-washout rate), and Tl score and r-WR were observed, but no such correlation was seen in dilated cardiomyopathy. In valvular heart disease, a decrease in myocardial perfusion associated with enlargement of the left ventricle appeared, while in dilated cardiomyopathy, there was a marked decrease in LVEF in proportion to the thallium defect. Therefore, it was assumed that left ventricular wall disorders occur due to myocardial metabolic disorders and coronary microcirculation disorders. (author)

    Technetium-99m pyrophosphate (PP/sub i/) is currently considered the best scanning agent for the diagnosis of acute myocardial infarction. False-positive scans have been reported in association with unstable angina, alcoholic cardiomyopathy, and ventricular aneurysms. In this study, 86 percent of patients (12/14) with either calcific aortic or mitral valvular heart disease had positive PP/sub i/ cardiac scintiscans and the location of the PP/sub i/ uptake was limited to the calcific valve in all (9/9) of the patients who underwent valve replacement surgery. Six patients with valvular disease without radiologic evidence of calcium had negative PP/sub i/ heart images. Three of these patients had surgical valve replacement, and in none was there increased uptake in the resected valve. Seventy-five percent of the patients with calcified aortic valves had localization of the PP/sub i/ activity to the area of the aortic valve, whereas 50 percent of the patients with calcified mitral valves showed a diffuse pattern of uptake on the cardiac image. In vitro demonstration of increased radioactivity in surgically removed cardiac valves warrants the conclusion that Tc-99m PP/sub i/ is taken up by calcified heart valves. We conclude that while PP/sub i/ heart scanning is a sensitive indicator of acute myocardial infarction, false-positive scans can occur in the presence of calcific valvular disease, due to localization of PP/sub i/ in the calcified portion of the valve

    Cine MR imaging shows details of cardiac valve motion and the turbulence caused by regurgitation and stenosis. In 30 patients, the area of turbulence proximal to regurgitant valves correlated well with the regurgitant fraction measured from right and left ventricular stroke volumes. Turbulence distal to stenotic valves did not correlate with the pressure gradient because abnormal valves that were not stenosed produced turbulence. Valve motion and the presence of thrombus were easier to assess than in conventional images. Cine MR imaging provides an important addition to conventional imaging in valvular regurgitation, but pressure gradients cannot be assessed in valvular stenosis

    Severe valvular heart disease is often complicated by congestive liver dysfunction, which greatly compromises the operative results. We evaluated congestive liver dysfunction by a novel approach using technetium-99m galactosyl human serum albumin ( 99m Tc-GSA) with liver scintigraphy. Between 1998 and 2004, we performed scintigraphy accompanied by 99m Tc-GSA in 28 patients who had valvular heart disease with moderate-to-severe tricuspid regurgitation and who showed symptoms of right heart failure. Based on the results, we calculated a receptor index (LHL15) and an index of blood clearance (HH15) and assessed the correlation between these factors and postoperative liver dysfunction, defined as the maximum serum total bilirubin level (max T-bil) as >2.0 mg/dl. Nineteen patients, including four who died in hospital, had postoperative liver dysfunction. The level of HH15 was significantly higher and the level of cholinesterase was significantly lower (P 99m Tc-GSA is a clinically useful predictor of postoperative liver dysfunction in patients with severe valvular disease.

    Rheumatic Hearth Disease (RHD) is still prevalent in our country and a great source of morbidity. This study was done with an objective to determine relative frequency of different valvular lesions of RHD presenting in a tertiary care hospital. Methods: This cross sectional study was conducted at the Cardiology Department of Hayatabad Medical Complex, Peshawar. A total of 171 cases of RHD were included through consecutive sampling technique. Results: There were 64.33% females. Mean age was 25.6 ± 6.95 years ranging from 15 to 40 years. The different percentage of valvular lesions in RHD were MR (59.06%), MS (46.78%), AR (43.85%) and mixed lesions (38.59%). Conclusion: Rheumatic heart disease is a very common disease in our community and mitral regurgitation is a predominant lesion at presentation. Females are usually affected more than males. (author)

    Abstract: An aquarium-housed, 6-mo-old African penguin (Spheniscus demersus) presented with acute respiratory distress. Auscultation revealed a grade II-III systolic murmur in the absence of adventitial sounds, and an enlarged heart without pulmonary edema was seen radiographically. Echocardiographic evaluation revealed atrioventricular (AV) valvular dysplasia and ventricular enlargement. The penguin was treated with enalapril, furosemide, and pimobendan but died within 3 wk of detection of the murmur. Congenital dysplasia of the right AV valve with right atrial and ventricular dilation and ventricular hypertrophy were diagnosed on postmortem examination.

    1978-01-01

    Radiopulmonary cardiography and lung scinti-scanning methods were employed for this study and performed on 59 patients with mitral valve disease and on 6 patients with aortic valve disease. For these examination, sup(99m)Tc-Pertechnetate and 131 I-MAA were administered intravenously as usual. Circulation time from the right heart to the lung (R-P), and from the lung to the left heart (P-L), and from the right heart to the left heart (R-L), as well as the value to the R-P and P-L ratio, and the U/L ratio in terms of blood distribution in the upper and lower parts of the lung were carefully estimated through these methods. Significant prolongation of the P-L interval and decrease in the R-P/P-L ratio were clearly observed in aortic insufficiency, mitral insufficiency, mitral stnosis, and mitral steno-insufficiency (MSI). On the contrary, prolongation of the R-P interval and an increase in the R-P/P-L ratio were recognized in patients with MSI + tricuspid insufficiency (TI). Radiopulmonary cardiograms revealed such characteristic patterns in each valvular heart disease, that differential diagnosis among valvular heart disease could be confirmed. The R-L interval was over 16 seconds in patients with MSI + TI who developed cardiac failure. The more the R-L interval was prolonged, the more severe the cardiac failure was found to be. A significant prolongation of the R-P interval and an increase in the R-P/P-L ratio, as well as a slight increase in the U/L ratio were clarly observed in the cases with severe right cardiac failure due to TI. On the other hand, remarked prolongation of the P-L interval, and a low value in the R-P/P-L ratio, as well as high value in the U/L ratio were seen in the cases with left cardiac failure. From these findings, the degree of severity and location of cardiac failure or of TI could be approximately evaluated. (author)

    Context Heart failure (HF) is the most common complication of infective endocarditis. However, clinical characteristics of HF in patients with infective endocarditis, use of surgical therapy, and their associations with patient outcome are not well described. Objectives To determine the clinical, echocardiographic, and microbiological variables associated with HF in patients with definite infective endocarditis and to examine variables independently associated with in-hospital and 1-year mortality for patients with infective endocarditis and HF, including the use and association of surgery with outcome. Design, Setting, and Patients The International Collaboration on Endocarditis–Prospective Cohort Study, a prospective, multicenter study enrolling 4166 patients with definite native- or prosthetic-valve infective endocarditis from 61 centers in 28 countries between June 2000 and December 2006. Main Outcome Measures In-hospital and 1-year mortality. Results Of 4075 patients with infective endocarditis and known HF status enrolled, 1359 (33.4% [95% CI, 31.9%–34.8%]) had HF, and 906 (66.7% [95% CI, 64.2%–69.2%]) were classified as having New York Heart Association class III or IV symptom status. Within the subset with HF, 839 (61.7% [95% CI, 59.2%–64.3%]) underwent valvular surgery during the index hospitalization. In-hospital mortality was 29.7% (95% CI, 27.2%–32.1%) for the entire HF cohort, with lower mortality observed in patients undergoing valvular surgery compared with medical therapy alone (20.6% [95% CI, 17.9%–23.4%] vs 44.8% [95% CI, 40.4%–49.0%], respectively; Pendocarditis complicated by HF, severity of HF was strongly associated with surgical therapy and subsequent mortality, whereas valvular surgery was associated with lower in-hospital and 1-year mortality.

    Valvular heart disease (VHD), particularly aortic valve disease, is prevalent with increasing incidence. When surgery is not possible, or when risks outweigh benefits, percutaneous treatment options may offer effective alternatives. However, procedures may not always go as planned, and frail patients or those whose symptoms are caused by other comorbidities may not benefit from valve intervention at all. Significant effort should be made to assess frailty, comorbidities and patient goals prior to intervention. Palliative care (PC) should play a critical role in the care of patients with severe valve disease. PC is specialised medical care that aims to optimise health-related quality of life by managing symptoms and clarifying patient values and goals of care. It should be implemented at the time of diagnosis and continue throughout the disease course. Because of the paucity of studies dedicated to the provision of PC to patients with advanced VHD, further research is needed. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Epidemiological differences can be found between Brazilian and European valvular heart disease patients. The prevalence of heart valve diseases due to rheumatic disease is significantly higher in the Brazilian compared with the European population. Therefore, they could have different risks during and after cardiac surgery. The aim of this study was to evaluate the applicability of the additive and logistic EuroSCORE and EuroSCORE II in a cohort of high-risk patients with valvular heart disease of predominantly rheumatic aetiology submitted to surgery. Between 1 February and 30 December 2009, 540 consecutive patients scheduled for valvular heart surgery were included in this study. In this set of patients, we examined the performance of the additive, logistic, and EuroSCORE II models for predicting in-hospital mortality. Calibration of each model was assessed by comparing predicted and observed in-hospital mortality and by the goodness of fit of the Hosmer-Lemeshow chi-square test. Discrimination performance of the model was evaluated with the receiver operating characteristic (ROC) curve analysis. The mean age was 56 ± 16 years, 50.6% were female, and the mortality rate was 16.0% (6.0% in elective surgery and 34.0% in emergency/urgency surgery). Mortality rates were estimated according to the additive and logistic EuroSCORE and EuroSCORE II at 6.1%, 8.7%, and 4.3%, respectively. The AUC was 0.76 (95% confidence interval [95% CI] 0.70-0.81) for the additive EuroSCORE, 0.76 (95% CI 0.70-0.81) for the logistic EuroSCORE and 0.81 (95% CI 0.76-0.86) for EuroSCORE II. Hosmer-Lemeshow goodness-of-fit statistics were P = 0.52, P = 0.07, and P = 0.12 for additive, logistic EuroSCORE, and EuroSCORE II. In this cohort of Brazilian patients with valvular heart disease submitted to surgical procedure, the EuroSCORE models had a good discriminatory capacity; however, the calibration was compromised because of an underestimation of the mortality rate.

    Full Text Available Abstract Background Amyloid deposition in heart is a common occurrence in systemic amyloidosis. But localised valvular amyloid deposits are very uncommon. It was only in 1922 that the cases of valvular amyloidosis were reported. Then in 1980, Goffin et al reported another type of valvular amyloidosis, which he called the dystrophic valvular amyloidosis. We report a case of aortic valve amyloidosis which is different from the yet described valvular amyloidosis. Case presentation A 72 years old gentleman underwent urgent aortic valve replacement. Intraoperatively, a lesion was found attached to the inferior surface of his bicuspid aortic valve. Histopathology examination of the valve revealed that the lesion contained amyloid deposits, identified as AL amyloidosis. The serum amyloid A protein (SAP scan was normal and showed no evidence of systemic amyloidosis. The ECG and echocardiogram were not consistent with cardiac amyloidosis. Conclusion Two major types of cardiac amyloidosis have been described in literature: primary-myelomatous type (occurs with systemic amyolidosis, and senile type(s. Recently, a localised cardiac dystrophic valvular amyloidosis has been described. In all previously reported cases, there was a strong association of localised valvular amyloidosis with calcific deposits. Ours is a unique case which differs from the previously reported cases of localised valvular amyloidosis. In this case, the lesion was not associated with any scar tissue. Also there was no calcific deposit found. This may well be a yet unknown type of isolated valvular amyloidosis.

    Full Text Available Introduction: Vascular and valvular calcifications are a frequent complication in dialyzed patients and are connected to an increased morbi-mortality. Many radiological methods (TAC multiple slices and with electrons emission have been used to investigate the presence of vascular calcifications in this population, but only few works have been focused on simple radiology. Objectives: The objectives of this work are to evaluate vascular calcifications by means of Kauppila index in hemodialysis prevalent patients, identify linked risk factors and determine their association with heart valves calcification. Methods: 95 stable patients under hemodialysis were surveyed during a period of 6 months longer. Abdominal Rx simple profile were performed on all patients to evaluate calcification of abdominal aorta by Kauppila index and twodimensional echocardiogram to detect valvular calcifications. Data were collected about sex, age, diabetes, Hypertension, tabaquism, dislipemia and bone-mineral metabolism. Results: 64.5% of the patients showed vascular calcifications. Average Kauppila index was 6.25. Age and time on dialysis correlated with vascular calcifications. In 31.6 % of individuals valvular calcifications were found, which presented significant association with diabetes and Kauppila Index. Conclusions: Vascular and valvular calcifications were frequent in the surveyed population. Kauppila index correlated with age, time on dialysis and valvular calcifications. Heart valves calcification was associated with diabetes.

    This study was performed to clarify whether the extent-score (Ex-Score) calculated by Tl-201 myocardial scintigraphy is a reliable indicator of the severity of myocardial damage and cardiac residual capacity in valvular heart diseases. The subjects consisted of 38 patients (10 with aortic regurgitation (AR), 4 with aortic stenosis (AS), 13 with mitral regurgitation (MR) and 11 with mitral stenosis (MS)). Ex-Scores were significantly correlated with the severity of myocardial damage found in biopsied specimens obtained intraoperatively (correlation efficiency to Ex-Score with cell diameter in AR, % fibrosis in AR, cell diameter in AS, electron microscopic score in MR and % fibrosis in MS was 0.873, 0.734, 0.970, 0.913 and 0.659, respectively). Ex-Scores were also correlated with cardiac residual capacity determined by radioisotope angiography (correlation efficiency to Ex-Score with %Δ ejection fraction in AR, %Δ end-systolic volume in MR, %Δ end-diastolic volume in MS was -0.764, 0.790 and -0.763, respectively). These results suggest that the severity of myocardial damage and cardiac residual capacity can be estimated by Tl-201 myocardial scintigraphy (Ex-Score) in valvular heart diseases. (author)

    The cerebral white matter hyperintensity (WMH) is frequently noted in patients with chronic heart disease. Long-term alteration of cardiac hemodynamics might have an influence on the mechanism of cerebral WMH. To investigate the association between chronically altered cardiac hemodynamics and severity of cerebral WMH in patients with chronic valvular heart disease. This cross-sectional analysis identified 303 consecutive patients at a tertiary referral center between 2008 and 2016 who were 50 years or older, and diagnosed with severe chronic valvular heart disease and underwent cardiac catherization, echocardiography, and received brain magnetic resonance imaging. Among these patients, 71 with other demonstrated cardiac disease, central nervous system disease, and/or without sufficient catheterization data were excluded, and the remaining 232 patients were included in further analyses. The site and mechanism of valve diseases, as well as clinical and medication profiles, were reviewed. Cardiac catheterization parameters such as right atrial (RA) mean pressure, right ventricular pressure, and aortic mean pressure were obtained. Comprehensive echocardiographic hemodynamic markers such as left ventricular (LV) ejection fraction, LV mass index, LV end diastolic volume, cardiac index, and E/e' ratio were also obtained. White matter hyperintensity volume was quantitatively evaluated using volumetric analysis. This study included 232 patients (103 men [44.4%] and 129 women [55.6%]; mean [SD] (range) age, 65.6 [8.8] (51-88) years) in the final analysis. The mean (SD) WMH volume was 5.93 (7.14) mL (median [interquartile range], 4.33 [1.33-8.62] mL), and mean (SD) RA pressure was 10.0 (4.7) mm Hg. From the catheterization data, 147 patients (63.4%) were classified as having a disease involving the mitral valve; 93 (40.1%), aortic valve; 37 (15.9%), tricuspid valve; and 4 (1.7%), pulmonary valve. In multivariate linear regression analysis, adjusting the type and mechanism of

    OBJECTIVE To assess platelet closure time (CT), mean platelet component (MPC) concentration, and platelet component distribution width (PCDW) in dogs with subclinical chronic valvular heart disease. ANIMALS 89 Cavalier King Charles Spaniels (CKCSs) and 39 control dogs (not CKCSs). PROCEDURES Platelet count, MPC concentration, PCDW, and Hct were measured by use of a hematology analyzer, and CT was measured by use of a platelet function analyzer. Murmur grade and echocardiographic variables (mitral valve regurgitant jet size relative to left atrial area, left atrial-to-aortic diameter ratio, and left ventricular internal dimensions) were recorded. Associations between explanatory variables (sex, age, murmur grade, echocardiographic variables, platelet count, and Hct) and outcomes (CT, MPC concentration, and PCDW) were examined by use of multivariate regression models. RESULTS A model with 5 variables best explained variation in CT (R(2), 0.74), with > 60% of the variance of CT explained by mitral valve regurgitant jet size. The model of best fit to explain variation in MPC concentration included only platelet count (R(2), 0.24). The model of best fit to explain variation in PCDW included platelet count and sex (R(2), 0.25). CONCLUSIONS AND CLINICAL RELEVANCE In this study, a significant effect of mitral valve regurgitant jet size on CT was consistent with platelet dysfunction. However, platelet activation, as assessed on the basis of the MPC concentration and PCDW, was not a feature of subclinical chronic valvular heart disease in CKCSs.

    Objective: To evaluate pulmonary hypertension (PH) and surgical therapeutic efficacy using first-pass radionuclide pulmonary perfusion imaging (FPPPI) and pulmonary perfusion imaging (PPI) in patients with PH of valvular heart disease. Methods: One hundred and sixteen patients with valvular disease were included in the study. Swan-Ganz catheterization, echocardiography, FPPPI and PPI were performed on all patients before surgery. The patients were divided into four groups. Results: 1) Correlation coefficients were 0.856, 0.503 and 0.572 (P<0.01) between lung equilibrium time (LET) by FPPPI, superior lung/low lung ratio (S/L) by PPI , systolic pulmonary arterial pressure (SPAP) from echocardiography and SPAP from the catheter manometer. 2)The sensitivity, specificity and accuracy of PAP using FPPPI measuring were 94.7%, 68.3% and 85.3%, respectively. The sensitivity, specificity and accuracy of PAP using PPI measuring were 78.8%, 52.8% and 70.7%, respectively. The sensitivity, specificity and accuracy of PAP using FPPPI plus PPI measuring were 96.4%, 72.7% and 89.7%, respectively. 3)LET by FPPPI before surgery and 5-14 d after surgery were (27.71 ± 10.85) and (20.96 ± 6.25) s, respectively (P<0.001). SPL by PPI were 1.43 ± 0.41 and 1.30 ± 0.35, respectively (P<0.001). 4) Complete improvement rates of LET in the PAP slightly risen group, moderately risen group and weightily risen group were 47.6%, 34.5% and 1/4, respectively; part improvement rates of LET for corresponding groups were 40.5%, 62.1% and 3/4, respectively (P<0.001). Complete improvement rates of SPL were 31.0%, 34.5% and 0/4, respectively; part improvement rates of SPL were 35.7%, 55.2% and 3/4, respectively (P<0.05). Complete improvement rates of LET + SPL were 57.1%, 58.6% and 1/4; part improvement rates of LET+SPL were 38.1%, 41.4% and 3/4, respectively (P<0.01). Conclusions: 1)FPPPI is better than PPI and echocardiography for evaluating PH in valvular heart disease. 2)Combined FPPPI and PPI can

    Transitions in the spectrum of valvular heart diseases (VHDs) in developed countries over the 20th century have been reported from clinical case series, but large, contemporary population-based studies are lacking. We used nationwide registers to identify all patients with a first diagnosis of VHD at Swedish hospitals between 2003 and 2010. Age-stratified and sex-stratified incidence of each VHD and adjusted comorbidity profiles were assessed. In the Swedish population (n=10 164 211), the incidence of VHD was 63.9 per 100 000 person-years, with aortic stenosis (AS; 47.2%), mitral regurgitation (MR; 24.2%) and aortic regurgitation (AR; 18.0%) contributing most of the VHD diagnoses. The majority of VHDs were diagnosed in the elderly (68.9% in subjects aged ≥65 years), but pulmonary valve disease incidence peaked in newborns. Incidences of AR, AS and MR were higher in men who were also more frequently diagnosed at an earlier age. Mitral stenosis (MS) incidence was higher in women. Rheumatic fever was rare. Half of AS cases had concomitant atherosclerotic vascular disease (48.4%), whereas concomitant heart failure and atrial fibrillation were common in mitral valve disease and tricuspid regurgitation. Other common comorbidities were thoracic aortic aneurysms in AR (10.3%), autoimmune disorders in MS (24.5%) and abdominal hernias or prolapse in MR (10.7%) and TR (10.3%). Clinically diagnosed VHD was primarily a disease of the elderly. Rheumatic fever was rare in Sweden, but specific VHDs showed a range of different comorbidity profiles . Pronounced sex-specific patterns were observed for AR and MS, for which the mechanisms remain incompletely understood. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available Objective: to compare the efficiency of using the values of transpulmonary (PiCCO and prepulmonary (Swan-Ganz catheter thermodilution as guides to targeted therapy for hemodynamic disorders in the surgical correction of mixed cardiac valvular defects. Subjects and methods. The study enrolled 40 patients operated on for acquired cardiac diseases who were randomized to two matched groups. Hemodynamics was monitored by means of a Swan-Ganz catheter in Group 1 and by transpulmonary thermodilution in Group 2. Anesthesia was maintained with propofol and fentanyl. Infusion therapy was performed using crystalloid and colloid solutions. Continuous intravenous infusion of inotropic agents was used when heart failure was developed. Hemodynamic, clinical, and laboratory parameters were estimated intraoperatively and within 24 hours postoperatively. Results. The groups did not differ in the degree of baseline heart failure, the duration of an operation and myocardial ischemia, and the length of extracorporeal circulation. In the PiCCO group, postoperative infusion volume was 33% higher than that in the Swan-Ganz group, which ensured increases in stroke volume and oxygen delivery in the early postoperative period (p<0.05. Respiratory support was 26% shorter in the PiCCO group (p<0.04. Conclusion. After surgical interventions for mixed cardiac defects, the targeted therapy algorithm based on transpulmonary thermodilution provided more steady-state values of hemodynamics and oxygen transport, which was followed by the increased scope of infusion therapy and the shorter length of postoperative mechanical ventilation than that based on hemodynamics being corrected from the values of prepul-monary thermodilution. Key words: transpulmonary thermodilution, targeted therapy, prepulmonary ther-modilution, acquired heart disease.

    First-pass radionuclide angiography (FPRA) in the 30/sup 0/ right anterior oblique and equilibrium gated radionuclide angiography (EGNA) in the 45/sup 0/ left anterior oblique were used for quantitative measurements of left ventricular ejection fraction (LVEF). Equipment used was a 400T gamma-camera interfaced with a Simis III Informatek computer. The results were compared with contrast angiography (CA). The aim of this study was to determine the sensitivity of both radionuclide techniques. The present data are based on 65 patients in whom CA and EGNA were performed. In 47 patients both FPRA and EGNA were performed. Results suggested that in ischemic heart disease (IHD) and valvular heart disease (VHD) the EGNA technique is well correlated with CA (r=0.9 and 0.73, respectively). FPRA correlated well only with CA in IHD (r=0.86), but not in VHD (r=0.18). This study indicates that both FPRA and EGNA are sensitive, noninvasive techniques for measuring ejection fraction in IHD, while in VHD, EGNA is more sensitive technique than FPRA.

    Summary Background: Rheumatic fever (RF) and rheumatic valvular heart disease (RHD) remain important medical, surgical and public health concerns in many parts of the world, especially in sub-Saharan Africa. However, there are no published data from Rwanda. We performed a RHD prevalence study in a randomly selected sample of Rwandan school children using the 2012 World Heart Federation (WHF) criteria. Methods: Echocardiographic assessment of 2 501 Rwandan school children from 10 schools in the Gasabo district near Kigali was carried out. Resulting data were evaluated by four experienced echocardiographers. Statistical analyses were carried out by statisticians. Results: RHD prevalence was 6.8/1 000 children examined (95% CI: 4.2/1 000–10.9/1 000). Seventeen met WHF criteria for RHD, 13 fulfilled criteria for ‘borderline’ RHD and four were ‘definite’ RHD. None of these 17 had been previously identified. Conclusion: These data indicate a significant burden of RHD in Rwanda and support a need for defined public health RF control programmes in children there. PMID:28252675

    Association between antiphospholipid syndrome in systemic lupus erythematosus (SLE) and valvular heart disease (VHD) is well reported, but relatively few studies have been carried out to establish the linkage between VHD and SLE itself. We aimed to investigate link between VHD and SLE and to evaluate the association of diverse factors with VHD among these patients in a large-scale population-based study. We used the databases of the largest state-mandated health service organization in Israel. All SLE patients were included (n = 5018) as well as their age and sex-matched controls (n = 25 090), creating a cross-sectional population-based study. Medical records of all subjects were analysed for documented VHD and the presence of antiphospholipid antibodies (aPLs). A logistic regression model was carried out to evaluate the diverse factors including SLE and aPLs as independent risk factors for VHD. Valvular heart disease were found to be more frequent among SLE group when compared to controls (aortic stenosis, 1·08% vs. 0·35% respectively, P < 0·001; aortic insufficiency, 1·32% vs. 0·29% respectively, P < 0·001; mitral stenosis, 0·74% vs. 0·21% respectively, P < 0·001; mitral insufficiency, 1·91% vs. 0·39% respectively, P < 0·001). Male sex, hypertension, aPLs and SLE were found to be significant independent risk factors for VHD. All VHD are more prevalent among SLE patients when compared to controls. SLE and aPLs are independent risk factor for VHD (OR of 2·46 and 1·7, respectively). Physicians must be aware of such significant association, and routine echocardiography should be considered in SLE patients regardless of their aPL status. © 2017 Stichting European Society for Clinical Investigation Journal Foundation.

    Hodgkin lymphoma (HL) survivors are at increased risk of developing valvular heart disease (VHD). We evaluated the determinants of the risk and the radiation dose-response. A case-control study was nested in a cohort of 1852 five-year HL survivors diagnosed at ages 15 to 41 years and treated between 1965 and 1995. Case patients had VHD of at least moderate severity as their first cardiovascular diagnosis following HL treatment. Control patients were matched to case patients for age, gender, and HL diagnosis date. Treatment and follow-up data were abstracted from medical records. Radiation doses to heart valves were estimated by reconstruction of individual treatments on representative computed tomography datasets. All statistical tests were two-sided. Eighty-nine case patients with VHD were identified (66 severe or life-threatening) and 200 control patients. Aortic (n = 63) and mitral valves (n = 42) were most frequently affected. Risks increased more than linearly with radiation dose. For doses to the affected valve(s) of less than or equal to 30, 31-35, 36-40, and more than 40 Gy, VHD rates increased by factors of 1.4, 3.1, 5.4, and 11.8, respectively (P trend < .001). Approximate 30-year cumulative risks were 3.0%, 6.4%, 9.3%, and 12.4% for the same dose categories. VHD rate increased with splenectomy by a factor of 2.3 (P = .02). Radiation dose to the heart valves can increase the risk of clinically significant VHD, especially at doses above 30 Gy. However, for patients with mediastinal involvement treated today with 20 or 30 Gy, the 30-year risk will be increased by only about 1.4%. These findings may be useful for patients and doctors both before treatment and during follow-up. © The Author 2015. Published by Oxford University Press.

Results: Eighty-nine case patients with VHD were identified (66 severe or life-threatening) and 200 control patients. Aortic (n = 63) and mitral valves (n = 42) were most frequently affected. Risks increased more than linearly with radiation dose. For doses to the affected valve(s) of less than or equal to 30, 31–35, 36–40, and more than 40 Gy, VHD rates increased by factors of 1.4, 3.1, 5.4, and 11.8, respectively (P trend < .001). Approximate 30-year cumulative risks were 3.0%, 6.4%, 9.3%, and 12.4% for the same dose categories. VHD rate increased with splenectomy by a factor of 2.3 (P = .02). Conclusions: Radiation dose to the heart valves can increase the risk for clinically significant VHD, especially at doses above 30 Gy. However, for patients with mediastinal involvement treated today with 20 or 30 Gy, the 30-year risk will be increased by only about 1.4%. These findings may be useful for patients and doctors both before treatment and during follow-up. PMID:25713164

    Yuan SM. Congenital heart defects in Williams syndrome. Turk J Pediatr 2017; 59: 225-232. Williams syndrome (WS), also known as Williams-Beuren syndrome, is a rare genetic disorder involving multiple systems including the circulatory system. However, the etiologies of the associated congenital heart defects in WS patients have not been sufficiently elucidated and represent therapeutic challenges. The typical congenital heart defects in WS were supravalvar aortic stenosis, pulmonary stenosis (both valvular and peripheral), aortic coarctation and mitral valvar prolapse. The atypical cardiovascular anomalies include tetralogy of Fallot, atrial septal defects, aortic and mitral valvular insufficiencies, bicuspid aortic valves, ventricular septal defects, total anomalous pulmonary venous return, double chambered right ventricle, Ebstein anomaly and arterial anomalies. Deletion of the elastin gene on chromosome 7q11.23 leads to deficiency or abnormal deposition of elastin during cardiovascular development, thereby leading to widespread cardiovascular abnormalities in WS. In this article, the distribution, treatment and surgical outcomes of typical and atypical cardiac defects in WS are discussed.

    First-pass radionuclide angiography (FPRA) in the 30 0 right anterior oblique and equilibrium gated radionuclide angiography (EGNA) in the 45 0 left anterior oblique were used for quantitative measurements of left ventricular ejection fraction (LVEF). Equipment used was a 400T gamma-camera interfaced with a Simis III Informatek computer. The results were compared with contrast angiography (CA). The aim of this study was to determine the sensitivity of both radionuclide techniques. The present data are based on 65 patients in whom CA and EGNA were performed. In 47 patients both FPRA and EGNA were performed. Results suggested that in ischemic heart disease (IHD) and valvular heart disease (VHD) the EGNA technique is well correlated with CA (r=0.9 and 0.73, respectively). FPRA correlated well only with CA in IHD (r=0.86), but not in VHD (r=0.18). This study indicates that both FPRA and EGNA are sensitive, noninvasive techniques for measuring ejection fraction in IHD, while in VHD, EGNA is more sensitive technique than FPRA. (orig.)

    Full Text Available Background: Hemodynamic changes induced by labor pain and apprehension in addition to physiological changes may pose risk to parturients with rheumatic heart disease (RHD. Therefore, it is important to provide adequate pain relief during labor in these patients. We planned this study to compare the efficacy and safety of epidural (E versus combined spinal - epidural (CSE for labor analgesia in parturients with rheumatic valvular heart disease. Methods: Twenty-five parturients with RHD included in this study were randomized to one of the two groups - E group (n = 12, received 6 mL of 0.0625% bupivacaine with 25 μg fentanyl or CSE group (n = 13, received 25 μg of fentanyl with 1.25 mg bupivacaine diluted to 1 mL in subarachnoid space. Afterward, a continuous infusion of 0.1% bupivacaine with 2 μg/mL fentanyl was started at 6-8 mL/h. Primary outcome, analgesic efficacy, was assessed by visual analog scale (VAS for pain. VAS ≤ 3 was considered as effective analgesia. Rescue analgesia in the form of epidural bolus was given if VAS > 3. Results: Demographic characteristics of the patients were comparable. Mitral stenosis was the predominant valvular lesion. The VAS at which the parturients received analgesia was comparable. The mean time to achieve effective analgesia was significantly faster in CSE group (4.46 ± 0.87 min compared with group E (15.09 ± 5.7 min (P < 0.001. Significantly lower median pain scores were recorded until the initial 15 min in CSE group. Afterward, median VAS for pain was comparable between the groups. VAS for pain was significantly low at all time intervals than baseline in both the groups. Maternal satisfaction and incidence of cesarean rate and complication were comparable between the groups. Conclusion: Both epidural and CSE are equally effective and safe for labor analgesia in parturients with rheumatic valvular heart disease. However, CSE technique provides a faster onset of analgesia.

    Radionuclide ventriculography has been used to assess quantitatively the extent of mitral and aortic regurgitation in 70 patients and compared to echocardiography and the finding of surgery. Two radionuclide parameters were measured: regurgitant index (RI) = left ventricular stroke counts/right ventricular stroke counts; and regurgitant fraction (RF) = left ventricular stroke counts-right ventricular stroke counts/left ventricular stroke counts. In 28 patients without valvular heart disease, the RI was 1.10 ± 0.15 and Rf was 10.3 ± 15.0%, respectively. However, in patients with valvular regurgitation, the RI and RF were 3.41 ± 1.73 and 61.1 ± 21.2%, respectively. A good correlation was found between the results obtained by radionuclide techniques and the findings of surgery and doppler studies. The level of concordance between RI and surgical findings was 91.7%. Follow up studies in 10 patients after valvular replacement surgery showed the RI and RF return to normal. These data suggested that radionuclide ventriculography is very useful for quantitative assessment of valvular regurgitation

    Left-sided valvular calcification is associated with cardiovascular disease (CVD) morbidity and mortality. Resting heart rate (RHR) may influence valvular calcium progression through shear stress. Whether RHR, an established CVD risk factor, is associated with valvular calcium progression is unknown. We assessed whether RHR predicts incidence and progression of mitral annular calcium (MAC) and aortic valve calcium (AVC) in a community-based cohort free of CVD at baseline. RHR was obtained from baseline electrocardiograms of 5498 MESA participants. MAC and AVC were quantified using Agatston scoring from cardiac computed tomography scans obtained at baseline and at a second examination during follow-up. We examined associations of RHR with incident MAC/AVC and annual change in MAC/AVC scores, after adjusting for demographics, CVD risk factors, physical activity, and atrioventricular nodal blocker use. At baseline, participants had mean age of 62 ± 10 years and mean RHR of 63 ± 10 bpm; 12.3% and 8.9% had prevalent AVC and MAC, respectively. Over a median of 2.3 years, 4.1% and 4.5% developed incident AVC and MAC, respectively. Each 10 bpm higher RHR was significantly associated with incident MAC [Risk Ratio 1.17 (95% CI 1.03-1.34)], but not incident AVC. However, RHR was associated with AVC progression [β = 1.62 (0.45-2.80) Agatston units/year for every 10 bpm increment], but not MAC progression. Higher RHR was associated with MAC incidence and AVC progression, independent of traditional CVD risk factors. Future studies are needed to determine whether modification of RHR through lifestyle or pharmacologic interventions can reduce valvular calcium incidence or progression.

    In 2013, the European Heart Rhythm Association (EHRA) published a Practical Guide on the use of non-VKA oral anticoagulants (NOACs) in patients with atrial fibrillation (AF) (Heidbuchel H, Verhamme P, Alings M, Antz M, Hacke W, Oldgren J, Sinnaeve P, Camm AJ, Kirchhof P, European Heart Rhythm A. European Heart Rhythm Association Practical Guide on the use of new oral anticoagulants in patients with non-valvular atrial fibrillation.

EHRA practical guide on the use of new oral anticoagulants in patients with non-valvular atrial fibrillation: executive summary. Eur Heart J 2013;34:2094-2106). The document received widespread interest, not only from cardiologists but also from neurologists, geriatricians, and general practitioners, as became evident from the distribution of >350 000 copies of its pocket version (the EHRA Key Message Booklet) world-wide. Since 2013, numerous new studies have appeared on different aspects of NOAC therapy in AF patients. Therefore, EHRA updated the Practical Guide, including new information but also providing balanced guiding in the many areas where prospective data are still lacking. The outline of the original guide that addressed 15 clinical scenarios has been preserved, but all chapters have been rewritten. Main changes in the Update comprise a discussion on the definition of 'non-valvular AF' and eligibility for NOAC therapy, inclusion of finalized information on the recently approved edoxaban, tailored dosing information dependent on concomitant drugs, and/or clinical characteristics, an expanded chapter on neurologic scenarios (ischaemic stroke or intracranial haemorrhage under NOAC), an updated anticoagulation card and more specifics on start-up and follow-up issues. There are also many new flow charts, like on appropriate switching between anticoagulants (VKA to NOAC or vice versa), default scenarios for

    Diseases of the heart valves constitute a major cause of cardiovascular morbidity and mortality worldwide with rheumatic heart disease (RHD) being the dominant form of valvular heart disease (VHD) in developing nations. The current study was undertaken at a tertiary care cardiac center with the objective of establishing the incidence and patterns of VHD by Echocardiography (Echo). Among the 136,098 first-time Echocardiograms performed between January 2010 and December 2012, an exclusion criterion of trivial and functional regurgitant lesions yielded a total of 13,289 cases of organic valvular heart disease as the study cohort. In RHD, the order of involvement of valves was mitral (60.2%), followed by aortic, tricuspid and pulmonary valves. Mitral stenosis, predominantly seen in females, was almost exclusively of rheumatic etiology (97.4%). The predominant form of isolated MR was rheumatic (41.1%) followed closely by myxomatous or mitral valve prolapse (40.8%). Isolated AS, more common in males, was the third most common valve lesion seen in 7.3% of cases. Degenerative calcification was the commonest cause of isolated AS (65.0%) followed by bicuspid aortic valve (BAV) (33.9%) and RHD (1.1%). Multiple valves were involved in more than a third of all cases (36.8%). The order of involvement was MS + MR > MS + AR > MR + AR > AS + AR > MR + AS > MS + AS. Overall, 9.7% of cases had organic tricuspid valve disease. RHD contributed most to the burden of VHD in the present study with calcific degeneration, myxomatous disease and BAV being the other major forms of VHD. Multiple valves were affected in more than a third of all cases. Copyright © 2014 Cardiological Society of India. Published by Elsevier B.V. All rights reserved.

    Cardiac ultrasound imaging systems are limited in the noninvasive quantification of valvular regurgitation due to indirect measurements and inaccurate hemodynamic assumptions. We recently demonstrated that the principle of integration of backscattered acoustic Doppler power times velocity can be used for flow quantification in valvular regurgitation directly at the vena contracta of a regurgitant flow jet. We now aimed to accomplish implementation of automated Doppler power flow analysis software on a standard cardiac ultrasound system utilizing novel matrix-array transducer technology with detailed description of system requirements, components and software contributing to the system. This system based on a 3.5 MHz, matrix-array cardiac ultrasound scanner (Sonos 5500, Philips Medical Systems) was validated by means of comprehensive experimental signal generator trials, in vitro flow phantom trials and in vivo testing in 48 patients with mitral regurgitation of different severity and etiology using magnetic resonance imaging (MRI) for reference. All measurements displayed good correlation to the reference values, indicating successful implementation of automated Doppler power flow analysis on a matrix-array ultrasound imaging system. Systematic underestimation of effective regurgitant orifice areas >0.65 cm(2) and volumes >40 ml was found due to currently limited Doppler beam width that could be readily overcome by the use of new generation 2D matrix-array technology. Automated flow quantification in valvular heart disease based on backscattered Doppler power can be fully implemented on board a routinely used matrix-array ultrasound imaging systems. Such automated Doppler power flow analysis of valvular regurgitant flow directly, noninvasively, and user independent overcomes the practical limitations of current techniques.

    With an increasing prevalence of patients with valvular heart disease (VHD), a dedicated management approach is needed. The challenges encountered are manifold and include appropriate diagnosis and quantification of valve lesion, organization of adequate follow-up, and making the right management decisions, in particular with regard to the timing and choice of interventions. Data from the Euro Heart Survey have shown a substantial discrepancy between guidelines and clinical practice in the field of VHD and many patients are denied surgery despite having clear indications. The concept of heart valve clinics (HVCs) is increasingly recognized as the way to proceed. At the same time, very few centres have developed such expertise, indicating that specific recommendations for the initial development and subsequent operating requirements of an HVC are needed. The aim of this position paper is to provide insights into the rationale, organization, structure, and expertise needed to establish and operate an HVC. Although the main goal is to improve the clinical management of patients with VHD, the impact of HVCs on education is of particular importance: larger patient volumes foster the required expertise among more senior physicians but are also fundamental for training new cardiologists, medical students, and nurses. Additional benefits arise from research opportunities resulting from such an organized structure and the delivery of standardized care protocols. The growing volume of patients with VHD, their changing characteristics, and the growing technological opportunities of refined diagnosis and treatment in addition to the potential dismal prognosis if overlooked mandate specialized evaluation and care by dedicated physicians working in a specialized environment that is called the HVC.

    Pulmonary hypertension in mitral valvular cardiac disease has been evaluated in 122 patients by a modified upper lung/lower count ratio using single-pass radionuclide angiocardiography. The mean upper lung/lower lung radio correlates well with pulmonary artery mean (r=0.483) and wedge pressure (r=0.804). After correction surgery of the cardiac valve, the ratio decreases and returns to normal range in patients judged clinically to have good surgical benifit. This modified method using single-pass technique provides additional simple, reproducible and nontraumatic results of regional pulmonary blood flow and appears to be correlated with the degree of pulmonary hypertension in mitral heart disease

    Risk factors for developing heart valve and ascending aortic disease are based mainly on retrospective data. To elucidate these factors in a prospective manner, we have performed a nested case-referent study using data from large, population-based surveys. A total of 777 patients operated for heart valve disease or disease of the ascending aorta had previously participated in population-based health surveys in Northern Sweden. Median time (interquartile range) from survey to surgery was 10.5 (9.0) years. Primary indications for surgery were aortic stenosis (41%), aortic regurgitation (12%), mitral regurgitation (23%), and dilatation/dissection of the ascending aorta (17%). For each case, referents were allocated, matched for age, sex, and geographical area. In multivariable models, surgery for aortic stenosis was predicted by hypertension, high cholesterol levels, diabetes mellitus, and active smoking. Surgery for aortic regurgitation was associated with a low cholesterol level, whereas a high cholesterol level predicted surgery for mitral regurgitation. Hypertension, blood pressure, and previous smoking predicted surgery for disease of the ascending aorta whereas diabetes mellitus was associated with reduced risk. After exclusion of cases with coronary atherosclerosis, only the inverse associations between cholesterol and aortic regurgitation and between diabetes mellitus and disease of the ascending aorta remained. This is the first truly prospective study of traditional cardiovascular risk factors and their association with valvular heart disease and disease of the ascending aorta. We confirm the strong association between traditional risk factors and aortic stenosis, but only in patients with concomitant coronary artery disease. In isolated valvular heart disease, the impact of traditional risk factors is varying. © 2017 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley.

    To assess the left ventricular (LV) function in valvular heart disease, we employed the preoperative dobutamine stress echocardiography and the myocardial scintigraphy. During the past 13 years, 37 of 324 the patients showed LV dysfunction with the % fractional shortening (%FS) of 25% or less in the preoperative echocardiogram. These patients were retrospectively divided into two groups; Group A (n=21): %FS has improved late after operation; Group B (n=16): %FS has deteriorated or LV failure occurred. The mean follow-up period was 84±54 months after valve surgery. No significant differences were observed in the preoperative characteristics and operative variables between these two groups. The dobutamine stress test had been performed in 8 patients in Group A and 9 patients in Group B preoperatively, and the maximum increase ratio of %FS (Δ%FS) was used for assessment. Seven patients in Group A had showed Δ%FS of more than 9%, while all patients in Group B had showed Δ%FS of less than 9%. Myocardial scintigraphy was performed in 11 patients of them, and another 22 patients with %FS of above 25% acted as the control group. The Defect Score, which was defined as the sum of defect scales in 25 LV segments, showed a significant difference between 11 patients with LV dysfunction and control group. The distribution of the Defect Score in each myocardial segment, showed significantly higher in the posterior and inferior LV segments. In addition, the perfusion defect on myocardial imaging was initiated in the junction between the septal and LV free wall, and extended from the posterior to the lateral wall along with deterioration of LV function. In conclusion, preoperative dobutamine stress echocardiography proved to be very useful for prediction of the postoperative LV function, and myocardial scintigraphy might be indicative of LV function even in valvular heart disease.

    Due to increasing aging, the epidemiology of VHD may have changed in China. This study aimed to provide contemporary information on the prevalence, distribution patterns, and etiology of severe VHD in China. This was a retrospective survey at Second Affiliated Hospital of Zhejiang University, which included all consecutive patients between 2010 and 2015. In all, 139,496 patients were enrolled. Among severe valve diseases, MR was the most frequent (n=946, 0.68%) followed by MS (n=524, 0.38%), AS (n=392, 0.28%), and AR (n=371, 0.27%). Severe MR and AS prevalence rates increased strikingly with age. Rheumatic heart disease had an prevalence of 1.56% (n=2179), and remained one of the most common causes of severe VHD in patients younger than 65years old (99.5% of MS with rheumatic; 27.6% of MR with rheumatic; 25.7% of AS with rheumatic; 31.6% of AR with rheumatic). Aortic valve calcification was the predominant AS etiology, and its prevalence greatly increased with age. In severe AR, rheumatic fever was the most common etiology in patients below 65; in those above 65, etiology was mostly degenerative. In severe primary MR, mitral valve prolapse was the most common cause. Prevalence of secondary MR increased with age, from 16.4% in 18-44years old to 51.7% in individuals ≥75. Severe valvular diseases are very common; rheumatic fever and degenerative valvular changes remain predominant causes in patients below 65 and older ones, respectively. Young adults present mainly with primary MR, while secondary MR is more common in elderly ones. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The study included 100 adults (48 men, 52 women with persistent and long-term persistent forms of AF and different valvular heart diseases. Mean patient age was 59 years. Mean AF duration was 4 years. All patients were prescribed antiarrhythmic therapy but it proved ineffective. In 15 % of patients, restoration of the sinus rhythm was attempted through electrical cardioversion but long-term control of the sinus rhythm wasn’t achieved. All patients were diagnosed with organic pathology of the mitral valve. Also, in 80 % of patients, relative insufficiency of the tricuspid valve was detected. Chronic heart failure functional class per NYHA was III. Size of the left atrium was 5 cm, mean left ventricular ejection fraction was 61 %. All patients underwent electrical cardioversion. After successful restoration of the sinus rhythm, endocardial electrophysiology study (EES of the heart was performed. Then, correction of valvular pathologies and the Labyrinth IIIB surgery were performed. Results. Examination of refractoriness of different parts of the atriums has shown that effective refractory period (ERP of the atrioventricular node was minimal compared to other parts of the atriums. Maximal ERP duration was observed in the upper part of the right atrium. Therefore, in patients with long history of AF, heterogeneity of atrial myocardium ERP duration is observed. In 17 % of patients, atrial vulnerability was detected. The area of atrial vulnerability was always associated with ERP. Its duration in patients with atrial vulnerability was significantly higher.Conclusion. Long

    Full Text Available BACKGROUND: Little is known about genetic basis and proteomics in valvular heart disease (VHD including rheumatic (RVD and degenerative (DVD valvular disease. The present proteomic study examined the hypothesis that certain proteins may be associated with the pathological changes in the plasma of VHD patients. METHODS AND RESULTS: Differential protein analysis in the plasma identified 18 differentially expressed protein spots and 14 corresponding proteins or polypeptides by two-dimensional electrophoresis and mass spectrometry in 120 subjects. Two up-regulated (complement C4A and carbonic anhydrase 1 and three down-regulated proteins (serotransferrin, alpha-1-antichymotrypsin, and vitronectin were validated by ELISA in enlarging samples. The plasma levels (n = 40 for each of complement C4A in RVD (715.8±35.6 vs. 594.7±28.2 ng/ml, P = 0.009 and carbonic anhydrase 1 (237.70±15.7 vs. 184.7±10.8 U/L, P = 0.007 in DVD patients were significantly higher and that of serotransferrin (2.36±0.20 vs. 2.93±0.16 mg/ml, P = 0.025 and alpha-1-antichymotrypsin (370.0±13.7 vs. 413.0±11.6 µg/ml, P = 0.019 in RVD patients were significantly lower than those in controls. The plasma vitronectin level in both RVD (281.3±11.0 vs. 323.2±10.0 µg/ml, P = 0.006 and DVD (283.6±11.4 vs. 323.2±10.0 µg/ml, P = 0.011 was significantly lower than those in normal controls. CONCLUSIONS: We have for the first time identified alterations of 14 differential proteins or polypeptides in the plasma of patients with various VHD. The elevation of plasma complement C4A in RVD and carbonic anhydrase 1 in DVD and the decrease of serotransferrin and alpha-1-antichymotrypsin in RVD patients may be useful biomarkers for these valvular diseases. The decreased plasma level of vitronectin - a protein related to the formation of valvular structure - in both RVD and DVD patients might indicate the possible genetic deficiency in these patients.

    The diagnosis of acute rheumatic fever (RF) is based on clinical findings. However, during the chronic phase of the disease, the clinical approach is not sufficient for the follow-up of the patients and the Doppler echocardiography is a tool for the diagnosis of cardiac involvement. Prognostic variables that influence long-term outcomes are not well known. 462 patients with RF according to Jones criteria were studied, and followed-up from the initial attack to 13.6 ± 4.6 years. All patients underwent clinical assessment and Doppler echocardiography for the detection of heart valve involvement in the acute and chronic phases. Multivariate logistic regression analysis was used to identify the factors influencing long-term heart valve disease. Carditis occurred in 55.8% and subclinical valvulitis in 35.3% patients. In the chronic phase, 33% of the patients had significant valvular heart disease. No normal Doppler echocardiography exam was observed on patients who had severe valvulitis, although heart auscultation had become normal in 13% of these. In the multivariate analysis, only the severity of carditis and the mitral and/or aortic valvulitis were associated with significant valvular heart disease. Chorea or arthritis were protective factors for significant valvular heart disease, odds ratio 0.41 (95% C.I. 0.22 – 0.77) and 0.43 (95% C.I. 0.23 – 0.82), respectively. Our study suggests that the use of Doppler echocardiography during RF helps to identify prognostic factors regarding the development of significant valvular heart disease. Initial severe carditis is an important factor in the long-term prognosis of chronic RHD, whereas arthritis and chore during the initial episode of RF appears to be protective. Strict secondary prophylaxis should be mandatory in high risk patients

    We compared thromboembolic (TE) and bleeding risks in patients with atrial fibrillation (AF) according to the new 'Evaluated Heartvalves, Rheumatic or Artificial' (EHRA) valve classification. Patients were divided into 3 categories: (i) EHRA type 1 corresponds to the previous 'valvular' AF patients, with either rheumatic mitral valve stenosis or mechanical prosthetic heart valves; (ii) EHRA type 2 includes AF patients with other valvular heart disease (VHD) and valve bioprosthesis or repair; and (iii) 'non-VHD controls' i.e. all AF patients with neither VHD nor post-surgical valve disease. Among 8962 AF patients seen between 2000 and 2010, 357 (4%) were EHRA type 1, 1754 (20%) were EHRA type 2 and 6851 (76%) non-VHD controls. EHRA type 2 patients were older and had a higher CHA 2 DS 2 -VASc and HAS-BLED scores than either type 1 and non-VHD patients. After a mean follow-up of 1264 ± 1160 days, the occurrence of TE events was higher in EHRA type 2 than non-VHD patients (HR (95%CI): 1.30 1.09-1.54), p = 0.003; also, p = 0.31 for type 1 vs 2, p = 0.68 for type 1 vs non-VHD controls). The rate of major BARC bleeding events for AF patients was higher in either EHRA type 1 (HR (95%CI): 3.16(2.11-4.72), p < 0.0001) or type 2 (HR (95%CI): 2.19(1.69-2.84), p < 0.0001) compared to non-VHD controls. The EHRA valve classification of AF patients with VHD appears useful in categorizing these patients, in terms of TE and bleeding risks. This classification can be used in clinical practice for appropriate choices of oral anticoagulation therapy and follow-up. Copyright © 2018 Elsevier B.V. All rights reserved.

    Direct oral anticoagulants (DOACs) are indicated for stroke prevention in patients with nonvalvular atrial fibrillation (NVAF), which, according to the American College of Cardiology/American Heart Association/Heart Rhythm Society atrial fibrillation (AF) guidelines, excludes patients with rheumatic mitral stenosis, a mechanical or bioprosthetic heart valve, or mitral valve repair. However, the data regarding use of DOACs in AF patients with other types of valvular heart disease (VHD) are unclear. We aimed to summarize and evaluate the literature regarding the safety and efficacy of DOAC use in NVAF patients with other types of VHD. After an extensive literature search, a total of 1 prospective controlled trial, 4 subanalyses, and 1 abstract were identified. Efficacy of the DOAC agents in NVAF patients with VHD mirrored the overall trial results. Bleeding risk was significantly increased in VHD patients treated with rivaroxaban, but not for dabigatran or apixaban. Of the bioprosthetic valve patients enrolled in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) trial, no safety or efficacy concerns were identified. In conclusion, subanalyses of DOAC landmark AF trials revealed that dabigatran, rivaroxaban, and apixaban may be safely used in AF patients with certain types of VHD: aortic stenosis, aortic regurgitation, and mitral regurgitation. More evidence is needed before routinely recommending these agents for patients with bioprosthetic valves or mild mitral stenosis. Patients with moderate to severe mitral stenosis or mechanical valves should continue to receive warfarin, as these patients were excluded from all landmark AF trials. © 2016 Wiley Periodicals, Inc.

    Valvular heart disease (VHD) affects a large number of patients annually. From a surgical standpoint, there are two primary options for valve replacement: mechanical or bioprosthetic. While there are clear advantages and disadvantages to either option, and recent literature does challenge some of the prior dictums of valve choice, a handful of absolutes remain true. Mechanical valves provide superior durability and freedom from re-operation when compared to their bioprosthetic counterparts, at the expense of bleeding or thrombotic complications associated with the need for lifelong oral anticoagulation. Unless a clear contraindication to oral anticoagulation exists, we recommend implanting mechanical valves for patients less than 60 years old and those who are older than 65 but maintained on anticoagulation for reasons other than their valvular disease. Bioprosthetic valves should be placed in patients who are greater than 65 years old or those patients who have a postoperative life expectancy of less than 10 years. Valve choice in patients between the ages of 60 to 70 is not dictated by guidelines and is less clear, with patient preference playing a larger role than their age range.

    Radiation to the mediastinum is a key component of treatment with curative intent for a range of cancers including Hodgkin's lymphoma and breast cancer. Exposure to radiation is associated with a risk of radiation-induced heart valve damage characterised by valve fibrosis and calcification. There is a latent interval of 10-20 years between radiation exposure and development of clinically significant heart valve disease. Risk is related to radiation dose received, interval from exposure and use of concomitant chemotherapy. Long-term outlook and the risk of valve surgery are related to the effects of radiation on mediastinal structures including pulmonary fibrosis and pericardial constriction. Dose prediction models to predict the risk of heart valve disease in the future and newer radiation techniques to reduce the radiation dose to the heart are being developed. Surveillance strategies for this cohort of cancer survivors at risk of developing significant heart valve complications are required. Published by the BMJ Publishing Group Limited.

    Objective: To evaluate the effect of intra-operative single intra venous dose of amiodarone on post operative cardiac arrhythmias in patients undergoing valvular heart surgery. Study Design: Randomized controlled trials. Place and Duration of surgery: This study was performed at Armed forces Institute of Cardiology Rawalpindi from Jan 01, 2011 to Dec 31, 2011. Patients and Methods: In this study 80 patients with rheumatic valvular heart disease and undergoing elective mitral valve replacement were randomly divided into two groups. Group I, n = 40 (Amiodarone group) was given single intravenous dose of amiodarone (5 mg/kg in 100 ml of saline over 30 min) before sternotomy incision. Group II, n = 40(control / placebo group) was given 100 ml of saline over 30 min. Result: In the amiodarone group, after removal of aortic cross clamp 75% patients had sinus rhythm compared to 47.5% in control group. p=0.045. Similarly 15% had AF, 5% JR and 5% VT/VF in amiodarone group in contrast to 32.5% with AF, 12.5% JR and 7.5% Vt/VF in control group. (p=0.045). Response to cardioversion was positive in 75% of the patients requiring shocks in amiodarone group as against 43.75% in the control group. (p=0.044). Conclusion: A single intravenous bolus dose of amiodarone is effective in decreasing the incidence of cardiac arrhythmias after mitral valve replacement in patients with rheumatic MVD. (author)

    Conclusion: The prevalence of inaudible valvular regurgitation is high in infants with structurally normal hearts. Multiple-valve involvement with regurgitation is not uncommon. Mild severity and low velocity on color Doppler, and the structural information provided by 2D imaging strongly suggest that these regurgitant flows are physiologically normal in infancy.

    The main indications for cardiac magnetic resonance imaging (MRI) in the evaluation of valvular heart disease are pathologies of the aortic and pulmonary valve. For mitral and tricuspid valve pathologies MRI is not the first line modality as these are usually well visualized by echocardiography. The advantages of MRI in valvular heart disease are a high reliability in the evaluation of ventricular volumes and function as well as the assessment of the perivalvular arterial or atrial structures. This reliability and the limitless access to any imaging plane partially compensates for the lower temporal and spatial resolution in comparison to echocardiography. In patients with congenital heart disease, cardiac MRI is established as a valuable diagnostic tool in daily clinical management, especially for the evaluation of pulmonary valve defects. Nevertheless, echocardiography remains the first-line diagnostic imaging tool for the foreseeable future. (orig.) [German] Die Untersuchung der Herzklappen in der MRT umfasst derzeit v. a. die Aorten- und Pulmonalisklappe. Pathologien der atrioventrikulaeren Klappen bilden demgegenueber nur selten die zentrale Fragestellung einer kardialen MRT-Untersuchung, da diese normalerweise einer echokardiographischen Untersuchung gut zugaenglich sind. Die Staerke der MRT ist die hohe Zuverlaessigkeit, mit der neben der Klappenmorphologie und -funktion die Funktionsparameter des jeweiligen Ventrikels und die Morphologie der nachgeschalteten Arterien bestimmt werden koennen. Dadurch kann die MRT die prinzipielle Schwaeche in der Orts- und Zeitaufloesung gegenueber der Echokardiographie teilweise kompensieren. Bei Patienten mit kongenitalen Herzvitien ist die MRT-basierte Klappendiagnostik fester Bestandteil des klinischen Managements. Das gilt besonders fuer die Evaluation der Pulmonalisklappe. Die Echokardiographie bleibt absehbar die Modalitaet der ersten Wahl fuer die Klappendiagnostik am Herzen. (orig.)

    In the field of valvular diseases, the year 2006 has been above all marked by the publication of new joint AHA/ACC guidelines. Besides, other publications included severe aortic stenosis, drug therapy in chronic aortic regurgitation, the indications for surgery in asymptomatic mitral regurgitation, as well as valve surgery in the elderly and mismatch severity after aortic valve replacement. In a series of 66 cases of aortic stenosis with poor LV function undergoing stress echocardiography, it has been shown that whether the absence of contractile reserve identifies a high-risk subgroup for aortic valve replacement (33% vs. 6%), this exam does not predict the functional prognosis and the post-operative LV function improvement. Hence, the absence of contractile reserve should not contra-indicate aortic valve replacement surgery, even though the prognosis is severe, since the natural prognosis is extremely severe. The question of aortic valve replacement in case of mild stenosis with the indication of CABG remains difficult. Taking into account the important mortality of redo surgery, a study was in favor of a systematic aortic valve replacement associated to CABG in patients 30 mmHg, a LVH and aortic valve calcifications. Old patients (>80 years) with severe aortic stenosis have a very severe natural prognosis, authorizing wide indications for aortic valve replacement, in the absence of important comorbidities. The use of vasodilators in severe chronic aortic regurgitation remains debated. In a randomized study comparing Nifedipine 40 mg vs. Enalapril 20 mm vs. placebo, it has been shown that the use of a vasodilator does not modify the time of valvular surgery at all. After a mean follow-up of 7 years, the rates of aortic valve replacement were identical in the 3 groups, and there wa no difference regarding the preoperative regurgitation volume, LV dimensions and mass, and LVEF. The timing for huge chronic and asymptomatic mitral regurgitation remains debated, even

    The use of non-vitamin K antagonist oral anticoagulants (NOACs) instead of vitamin K antagonists (VKAs) in patients with atrial fibrillation (AF) and coexisting valvular heart disease (VHD) is of substantial interest. This study explored outcomes in patients with AF with and without VHD in the ENGAGE AF-TIMI 48 (Effective Anticoagulation with factor Xa Next Generation in Atrial Fibrillation-Thrombolysis In Myocardial Infarction 48) trial, comparing edoxaban with warfarin. Valvular heart disease was defined as history or baseline echocardiography evidence of at least moderate aortic/mitral regurgitation, aortic stenosis, or prior valve surgery (bioprosthesis replacement, valve repair, valvuloplasty). Patients with moderate to severe mitral stenosis or mechanical heart valves were excluded from the trial. Comparisons were made of rates of stroke/systemic embolic event (SSEE), major bleeding, additional efficacy and safety outcomes, as well as net clinical outcomes, in patients with or without VHD treated with edoxaban or warfarin, using adjusted Cox proportional hazards. After adjustment for multiple baseline characteristics, compared with no-VHD patients (n = 18,222), VHD patients (n = 2,824) had a similar rate of SSEE but higher rates of death (hazard ratio [HR]: 1.40; 95% confidence interval [CI]:1.26 to 1.56; p <0.001), major adverse cardiovascular events (HR: 1.29; 95% CI: 1.16 to 1.43; p <0.001), and major bleeding (HR: 1.21; 95% CI: 1.03 to 1.42; p = 0.02). Higher-dose edoxaban regimen had efficacy similar to warfarin in the presence of VHD (for SSEE, HR: 0.69; 95% CI: 0.44 to 1.07, in patients with VHD, and HR: 0.91; 95% CI: 0.77 to 1.07, in patients without VHD; p interaction [p int ] = 0.26; and for less major bleeding, HR: 0.74; 95% CI: 0.53 to 1.02 in patients with VHD, and HR: 0.82; 95% CI: 0.71 to 0.94, in patients with no VHD; p int  = 0.57). The presence of VHD increased the risk of death, major adverse cardiovascular events, and major

    Platelet survival time was studied in 18 patients suffering from valvular heart disease using a modified 75 Se-methionine method. 9 of 18 patients underwent surgery for heart valve replacement. Platelet survival time was determined before and 6 months after treatment with placebo of sulfinpyrazone in a double blind study. Before treatment and surgery, platelet survival time was significantly reduced in patients with a history of embolism (P < 0.0048). In patients receiving valve replacement, platelet survival time was shortened both in the sulfinpyrazone and placebo groups 6 months after surgery. Of the 9 patients not receiving prostheses and with a thrombotic history, treatment with placebo and sulfinpyrazone resulted in improved platelet survival times. (author)

    Cardiovascular diseases are the leading cause of death worldwide. Valvular heart disease often requires valve repair or replacement. Today, surgery uses xenograft—porcine or bovine pericardium. However, bioprosthetic valves do not ensure sufficient durability. We investigated 0.6% glutaraldehyde-treated porcine pericardium to define its properties. Using a tensile test stand, we studied characteristics of the polymeric material—expanded polytetrafluoroethylene (ePTFE)—and compared it to xenopericardium. The artificial material provides a better durability; it has higher elastic modulus and ultimate tensile strength. However, ePTFE samples demonstrated direction anisotropy due to extrusion features. It requires the enhancement of quality of the ePTFE sheet or investigation of other polymeric materials to find the adequate replacement for bioprosthetic heart valves.

    Iodine-123-metaiodobenzylguanidine (MIBG) imaging was used to assess myocardial adrenergic nerve activity in patients with heart failure. MIBG planar images were obtained in 94 patients. The uptake of MIBG, calculated as the heart-to-mediastinum activity ratio in the immediate image (15 min), showed a significant decrease only in patients with severe heart failure due to cardiomyopathy, but was not changed in those with valvular diseases. Storage and release of MIBG, calculated as the percentage myocardial MIBG washout from 15 min to 4 hours after isotope injection, was substantially accelerated in both patients with cardiomyopathy and valvular diseases in proportion to the severity of heart failure. These data suggest that, in severe heart failure associated with cardiomyopathy, norepinephrine uptake is reduced. Also, myocardial adrenergic nerve activity is accelerated in proportion to the severity of heart failure independent of the underlying cause. MIBG images were analyzed in 20 patients with mitral stenosis with the same methods to clarify whether myocardial adrenergic nerve activity is different in patients with heart failure without left ventricular volume or pressure overload. Myocardial uptake of MIBG did not show any significant difference. The percentage myocardial MIBG washout was increased in patients with severe heart failure. The closest correlation was between myocardial washout and cardiac output. In heart failure due to mitral stenosis, myocardial adrenergic nerve activity is intensified. Decrease in cardiac output associated with mitral stenosis acts as a potent stimulus for this intensification. (author)

    Since the introduction of transcatheter structural heart intervention, the term "structural heart disease" has been widely used in the field of cardiology. Structural heart disease refers to congenital heart disease, valvular heart disease, and cardiomyopathy. In structural heart disease, valvular heart disease is frequently identified in the elderly. Of note, the number of patients who suffer from aortic stenosis (AS) and mitral regurgitation (MR) is increasing in developed countries because of the aging of the populations. Transcatheter aortic valve replacement and percutaneous mitral valve repair has been widely used for AS and MR, individually. Echocardiography is the gold standard modality for initial diagnosis and subsequent evaluation of AS and MR, although the difficulties in assessing patients with these diseases still remain. Here, we review the clinical usefulness and prognostic impact of exercise echocardiography on structural heart disease, particularly on AS and MR.

Platelet survival time was determined before and 6 months after treatment with placebo of sulfinpyrazone in a double blind study. Before treatment and surgery, platelet survival time was significantly reduced in patients with a history of embolism (P < 0.0048). In patients receiving valve replacement, platelet survival time was shortened both in the sulfinpyrazone and placebo groups 6 months after surgery. Of the 9 patients not receiving prostheses and with a thrombotic history, treatment with placebo and sulfinpyrazone resulted in improved platelet survival times.

    Physical check-ups among athletes with valvular heart disease are of significant relevance. In athletes with mitral valve stenosis the extent of allowed physical activity is dependant on the size of the left atrium and the severity of the valve defect. Patients with mild-to-moderate mitral valve regurgitation can participate in all types of sport associated with low and moderate isometric stress and moderate dynamic stress. Patients under anticoagulation should not participate in any type of contact sport. Asymptomatic athletes with mild aortic valve stenosis can take part in all types of sport, as long as left ventricular function and size are normal, a normal response to exercise at the level performed during athletic activities is present and there are no arrhythmias. Asymptomatic athletes with moderate aortic valve stenosis should only take part in sports with low dynamic and static stress. Aortic valve regurgitation is often present due to connective tissue disease of a bicuspid valve. Athletes with mild aortic valve regurgitation, with normal end diastolic left ventricular size and systolic function can participate in all types of sport. A mitral valve prolapse is often associated with structural diseases of the myocardium and endocardium. In patients with mitral valve prolapse Holter-ECG monitoring should also be performed to detect significant arrhythmias. All athletes with known valvular heart disease, a previous history of infective endocarditis and valve surgery should receive endocarditis prophylaxis before dental, oral, respiratory, intestinal and genitourinary procedures associated with bacteraemia. Sport activities have to be avoided during active infection with fever.

    Aim: While the incidence of rheumatic heart disease has declined dramatically over the last half-century, the number of valve surgeries has not changed. This study was undertaken to define the most common type of valvular heart disease requiring surgery today, and determine in-hospital surgical mortality and length-of-stay (LOS) for isolated aortic or mitral valve surgery in a United States tertiary-care hospital. Methods: Patients with valve surgery between January 2002 to June 2008 at The Ohio State University Medical Center were studied. Patients only with isolated aortic or mitral valve surgery were analyzed. Results: From 915 patients undergoing at least aortic or mitral valve surgery, the majority had concomitant cardiac proce-dures mostly coronary artery bypass grafting (CABG); only 340 patients had isolated aortic (n=204) or mitral (n=136) valve surgery. In-hospital surgical mortality for mitral regurgitation (n=119), aortic stenosis (n=151), aortic insufficiency (n=53) and mitral stenosis (n=17) was 2.5% (replacement 3.4%; repair 1.6%), 3.9%, 5.6% and 5.8%, respectively (p=NS). Median LOS for aortic insufficiency, aortic stenosis, mitral regurgitation, and mitral stenosis was 7, 8, 9 (replacement 11.5; repair 7) and 11 days, respectively (p<0.05 for group). In-hospital surgical mortality for single valve surgery plus CABG was 10.2% (p<0.005 compared to single valve surgery). Conclusions: Aortic stenosis and mitral regurgitation are the most common valvular lesions requiring surgery today. Surgery for isolated aortic or mitral valve disease has low in-hospital mortality with modest LOS. Concomitant CABG with valve surgery increases mortality substantially. Hospital analysis is needed to monitor quality and stimulate improvement among Institutions. PMID:24339838

    Valvular aortic stenosis is the second most prevalent adult valve disease in the United States and causes progressive pressure overload, invariably leading to life-threatening complications. Surgical aortic valve replacement and, more recently, transcatheter aortic valve replacement effectively relieve the hemodynamic burden and improve the symptoms and survival of affected individuals. However, according to current American College of Cardiology/American Heart Association guidelines on the management of valvular heart disease, the indications for aortic valve replacement, including transcatheter aortic valve replacement, are based primarily on the development of clinical symptoms, because their presence indicates a dismal prognosis. Left ventricular hypertrophy develops in a sizeable proportion of patients before the onset of symptoms, and a growing body of literature demonstrates that regression of left ventricular hypertrophy resulting from aortic stenosis is incomplete after aortic valve replacement and associated with adverse early postoperative outcomes and worse long-term outcomes. Thus, reliance on the development of symptoms alone without consideration of structural abnormalities of the myocardium for optimal timing of aortic valve replacement potentially constitutes a missed opportunity to prevent postoperative morbidity and mortality from severe aortic stenosis, especially in the face of the quickly expanding indications of lower-risk transcatheter aortic valve replacement. The purpose of this review is to discuss the mechanisms and clinical implications of left ventricular hypertrophy in severe valvular aortic stenosis, which may eventually move to center stage as an indication for aortic valve replacement in the asymptomatic patient.

    Our goal was to establish a prediction score and protocol for the preoperative prediction of significant coronary artery disease (CAD) in patients with rheumatic valvular heart disease. Using multivariate logistic regression analysis, we validated the model based on 490 patients without a history of myocardial infarction and who underwent preoperative screening coronary angiography. Significant CAD was defined as ≥50% narrowing of the diameter of the lumen of the left main coronary artery or ≥70% narrowing of the diameter of the lumen of the left anterior descending coronary artery, left circumflex artery or right coronary artery. Significant CAD was present in 9.8% of patients. Age, smoking, diabetes mellitus, diastolic blood pressure, low-density lipoprotein cholesterol and ischaemia evident on an electrocardiogram were independently associated with significant CAD and were entered into the multivariate model. According to the logistic regression predictive risk score, preoperative coronary angiography is recommended in (i) postmenopausal women between 50 and 59 years of age with ≥9.1% logistic regression predictive risk score; (ii) postmenopausal women who are ≥60 years old with a logistic regression predictive risk score ≥6.6% and (iii) men ≥50 years old whose logistic regression predictive risk score was ≥2.8%. Based on this predictive model, 246 (50.2%) preoperative coronary angiograms could be safely avoided. The negative predictive value of the model was 98.8% (246 of 249). This model was accurate for the preoperative prediction of significant CAD in patients with rheumatic valvular heart disease. This model must be validated in larger cohorts and various populations.

    In the United States, valvular heart disease (VHD) has a prevalence of 2.5%, most commonly presenting as aortic stenosis (AS) or mitral valve regurgitation (MR) and increasingly observed to be of a degenerative etiology. Women frequently have latent symptoms despite significant disease, and it is therefore pertinent to consider both clinical symptoms and imaging findings for decision-making on treatment. Indeed, significant advances have been made in noninvasive imaging allowing for more accurate diagnosis and disease prognostication. While echo remains the standard diagnostic test, multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) provide complementary information on aortic valve calcification and left ventricular (LV) function, respectively. For any given calcification load or increase in calcification density of the aortic valve, women have greater increase in aortic valve stenosis severity than men; thus, moderate AS in women warrants closer attention. MRI allows identification of different patterns of hypertrophy and remodeling, extent of LV fibrosis, and insights into differential reverse remodeling and clinical outcomes in men and women. In conjunction with surgical treatment, percutaneous technologies are being increasingly used in the management of VHD. Nearly 50% of patients undergoing transcatheter aortic valve replacement (TAVR) are women. In high- or intermediate-risk subjects with significant symptomatic AS, TAVR has been shown to be noninferior to surgical AVR (SAVR). Notably, whereas both treatment strategies are equally effective in men, transfemoral TAVR has been shown to be superior to SAVR resulting in better survival in women. Analogously, few data have examined sex differences with percutaneous MitraClip devices in the treatment of degenerative MR, and men and women appear to have equivalent composite outcomes. Randomized clinical trial data are presently awaited for outcomes in the percutaneous treatment of

    The objective of the present study is to analyze the epidemiological profile of patients with abnormal valvular structure and function and highlight the etiological spectrum and management of valvular heart disease (VHD) in a single cardiovascular center of Southern China in five years. The retrospective study included 19,428 consecutive patients (9,441 men and 9,987 women with a mean age of 52.03±20.50 years) with abnormal valvular structure and function who were screened by transthoracic echocardiography (TTE) or transesophageal echocardiography (TEE) at the in-patient department of Guangdong General Hospital from January 2009 to December 2013. Data on baseline characteristics, potential etiology, treatment strategies and discharge outcomes were collected from electronic medical records. There were 13,549 (69.7%) patients with relatively definite etiology for VHD. VHD was rheumatic in 7,197 (37.0%) patients, congenital in 2,697 (13.9%), degenerative in 2,241 (11.5%), ischemic in 2,460 (12.7%). The prevalence decreased significantly in rheumatic VHD from 2009 to 2013 (from 42.8% to 32.8%, P<0.001), but increased markedly in congenital VHD (from 9.0% to 12.3%, P<0.001), ischemic VHD (from 9.2% to 11.3%, P=0.003) and degenerative VHD (from 8.8% to 14.5%, P<0.001). Meantime, the prevalence of ischemic VHD increased after the age of 45, similar to that of degenerative VHD. From 2009 to 2013, the proportion of patients with VHD undergoing open cardiac valvular surgery decreased (from 49.5% to 44.3%, P<0.001) and that of patients treated with general medication increased (from 49.2% to 54.1%, P<0.001). However, there was markedly increment in video-assisted thoracoscopic surgery (VATS) from 2009 to 2013 (from 0.3% to 4.4%, P<0.001). Increasing tendencies were showed in aortic mechanical valve replacement (from 32.1% to 34.5%, P=0.001) and double mechanical valve replacement (from 20.9% to 22.3%, P=0.035), especially in mitral valvuloplasty (from 8.5% to 15.7%, P<0

    The left ventricular (LV) remodeling process associated with significant valvular heart disease (VHD) is characterized by an increase of myocardial interstitial space with deposition of collagen and loss of myofibers. These changes occur before LV systolic function deteriorates or the patient develops symptoms. Cardiovascular magnetic resonance (CMR) permits assessment of reactive fibrosis, with the use of T1 mapping techniques, and replacement fibrosis, with the use of late gadolinium contrast enhancement. In addition, functional consequences of these structural changes can be evaluated with myocardial tagging and feature tracking CMR, which assess the active deformation (strain) of the LV myocardium. Several studies have demonstrated that CMR techniques may be more sensitive than the conventional measures (LV ejection fraction or LV dimensions) to detect these structural and functional changes in patients with severe left-sided VHD and have shown that myocardial fibrosis may not be reversible after valve surgery. More important, the presence of myocardial fibrosis has been associated with lesser improvement in clinical symptoms and recovery of LV systolic function. Whether assessment of myocardial fibrosis may better select the patients with severe left-sided VHD who may benefit from surgery in terms of LV function and clinical symptoms improvement needs to be demonstrated in prospective studies. The present review article summarizes the current status of CMR techniques to assess myocardial fibrosis and appraises the current evidence on the use of these techniques for risk stratification of patients with severe aortic stenosis or regurgitation and mitral regurgitation.

    Full Text Available Introduction The risk of developing conduction disturbances after coronary bypass grafting (CABG or valvular surgery has been well established in previous studies, leading to permanent pacemaker implantation in about 2% to 3% of patients, and in 10% of patients undergoing repeat cardiac surgery.We sought to determine the incidence, features and predictors of conduction disorders in the immediate post-operative period of patients subjected to open-heart surgery, and the need for permanent pacemaker implantation.Material and Method We prospectively studied 374 consecutive patients who underwent open-heart surgery in our institution: coronary artery bypass (CABG (n=128, Mitral valve replacement(MVR(n=18, aortic valve replacement(AVR (n=21, MVR and AVR(n=56, repair of ventricular septal defect (VSD (n=51, repair of tetralogy of Fallot (TOF (n=57,CABG and valvular surgery (n=6, others (n=37.Results Among 374 patients included in our study (mean age 34.46±25.68; 146 males, 192 developed new conduction disorders: symptomatic sinus bradycardia in 8%, atrial fibrillation with slow ventricular response (AF in 4.5%, first-degree atrioventricular block (AVBin 6.4%, second-degree AVB in 0.3%, third-degree AVB in 7%, new right bundle branch block (RBBB in 33%, and new left bundle branch block (LBBB in 2.1%. In 5.6% patients, a permanent pacemaker was implanted, 47.6% of them underwent valvular surgery. In 44.1% of patients the conduction defects occurred in the first 48 hr. after surgery. In CABG group, 29.7% of patients developed new conduction disturbances; the most common of them was symptomatic sinus bradycardia. After valvular surgery 44.2% of patients developed conduction disturbances, of those the most common was atrial fibrillation with slow ventricular response . After VSD and TOF repair, the most common conduction disturbance was new RBBB. Perioperative myocardial infarction (MI occurred in 1.9% of patients. The occurrence conduction disturbance

    von Willebrand Factor (vWF) is a well-known mediator of hemostasis and vascular inflammation. Its dynamic modulation in the bloodstream, according to hemodynamic conditions, makes it an appealing biomarker in patients with valvular heart disease (VHD). Recent studies highlight the close connection between vWF and VHD, with possible implications in the pathogenesis of VHD, promoting valve aging and calcification or favoring the development of infective endocarditis. Moreover, vWF has been recently proposed as a new diagnostic and prognostic tool in patients with valve stenosis or regurgitation, showing a strict correlation with severity of valve disease, outcome, and bleeding (Heyde syndrome). A novel role for vWF is also emerging in patients undergoing percutaneous or surgical valve repair/replacement to select and stratify patients, evaluate periprocedural bleeding risk, and detect procedural complications. We also report our single-center experience, suggesting, for the first time, possible clinical implications for vWF in percutaneous mitral valve repair (MitraClip). This review summarizes recent advances in the role of vWF in VHD with an updated overview going from bench to operating room.

    Ramírez-Giraldo, Ana María; Restrepo, Diana

    Bipolar disorder is a chronic and recurrent mood disease that includes symptoms that fluctuate from euphoria to depression. As a mood disorder, itis one of the main contraindications for transplantation procedures. The case is presented of a patient with bipolar disorder who had a heart transplant after a cardiac arrest. Heart transplantation is the treatment of choice in patients with heart failure and arrhythmias that do not respond to conventional treatment. Case report and narrative review of literature. A 34-year-old woman with bipolar disorder diagnosed when she was 13, treated with lithium and aripiprazole. She required a heart transplant as the only therapeutic option, after presenting with ventricular tachycardia refractory to conventional treatment. The patient did not suffer an emotional decompensation with the removal of the lithium and aripiprazole that were associated with prolonged QTc interval, and remained eurhythmic throughout the process. Heart transplantation can be performed safely and successfully in patients with bipolar disorder, when suitably followed-up by a liaison psychiatry group. Bipolar disorder should not be considered as an absolute contraindication for heart transplantation. Copyright © 2017 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

    Prosthetic heart valve dysfunction due to thrombus or pannus formation can be a life-threatening complication. The present report describes a 47-year-old woman who developed valvular cardiomyopathy after chorda-sparing mitral valve replacement, and subsequently underwent heart transplantation for progressive heart failure. The explanted mitral valve prosthesis showed significant thrombus and pannus leading to reduced leaflet mobility and valvular stenosis. The present report illustrates the role of the subvalvular apparatus and pannus in prosthesis dysfunction. PMID:19279993

    Concomitant chronic kidney disease (CKD) is common in patients with significant valvular heart disease (VHD). This study sought to evaluate the clinical benefit of valvular surgery in patients with concomitant CKD.We evaluated 349 patients with significant VHD who were referred for surgery. Patients were divided into those with CKD stage ≥ 3 (CKD patients; n = 88) and those with CKD stage 1 or 2 (no CKD patients; n = 261). 63 patients did not receive surgery, of which 20 patients had CKD and 43 had no CKD. Mortality and change in eGFR were assessed after a median follow-up of 21 months.In the whole study population, 25% of the patients had CKD and these patients had higher mortality than those with no CKD. The annual mortality rates of patients with CKD who did and did not undergo surgery were 7.9% and 28.0%, respectively. In patients with no CKD, the annual mortality rates of those who did and did not undergo surgery were 1.8% and 2.3%, respectively. Importantly, surgery was associated with significant survival benefit in patients with CKD (log-rank test, P < 0.01), but was neutral in patients with no CKD. Multivariable analysis confirmed the survival benefit of valvular surgery in all patients, which was most significant in patients with CKD. Furthermore, eGFR was preserved in patients who underwent valvular surgery but declined significantly in those who did not.CKD is common in patients with significant VHD and, if left untreated surgically, these patients exhibit a high mortality.

    To evaluate the presence, size and location of enlarged mediastinal lymph nodes (LNs) in patients with valvular heart disease (VHD) using computed tomography scans in correlation with ejection fraction (EF). We retrospectively evaluated 30 patients with VHD, without pre-existing diseases that could cause lymphadenopathy (LAP). The presence, size, and location of LNs greater than 1 cm in short axis diameter were evaluated. The location of mediastinal LNs was recorded according to the International Association for the Study of Lung Cancer. Furthermore, we evaluated the presence of pulmonary edema, pleural effusion, and other thoracic abnormalities and evaluated EF of the heart on transthoracic echocardiography. Sixteen patients (53%) had at least 1 enlarged mediastinal LN. The most frequent locations were lower paratracheal (4R, n = 8/4L, n = 6), subcarinal (7, n = 5) and right upper paratracheal (2R, n = 4) regions. The frequency of mediastinal LAP was higher in patients with aortic regurgitation (2 of 2, 100%) followed by mitral regurgitation (8 of 11, 73%); it was also high in patients with pulmonary edema (80%), pleural effusion (81%), or both (77%), as compared to patients without pulmonary edema or pleural effusion (17%) (p = 0.001). Ten of 30 patients showed an abnormal EF of < 55%; among them, 8 had mediastinal LAP. However, the relationship between EF and LAP was not statistically significant (p = 0.058). Mediastinal LN enlargement is common in patients with VHD, especially in cases of pulmonary edema and pleural effusion. Enlarged mediastinal LNs were frequently observed with abnormal EF, however, the relationship between EF and mediastinal LAP was not statistically significant.

    In an attempt to increase the therapeutic potential for myocardial regeneration, there is a quest for new cell sources and types for cell therapy protocols. The pathophysiology of heart diseases may affect cellular characteristics and therapeutic results. To study the proliferative and differentiation potential of mesenchymal stem cells (MSC), isolated from bone marrow (BM) of sternum, we made a comparative analysis between samples of patients with ischemic (IHD) or non-ischemic valvular (VHD) heart diseases. We included patients with IHD (n = 42) or VHD (n = 20), with average age of 60 years and no differences in cardiovascular risk factors. BM samples were collected (16.4 ± 6 mL) and submitted to centrifugation with Ficoll-Paque, yielding 4.5 ± 1.5 × 10 7  cells/mL. Morphology, immunophenotype and differentiation ability had proven that the cultivated sternal BM cells had MSC features. The colony forming unit-fibroblast (CFU-F) frequency was similar between groups (p = 0.510), but VHD samples showed positive correlation to plated cells vs. CFU-F number (r = 0.499, p = 0.049). The MSC culture was established in 29% of collected samples, achieved passage 9, without significant difference in expansion kinetics between groups (p > 0.05). Dyslipidemia and the use of statins was associated with culture establishment for IHD patients (p = 0.049 and p = 0.006, respectively). Together, these results show that the sternum bone can be used as a source for MSC isolation, and that ischemic or valvular diseases do not influence the cellular yield, culture establishment or in vitro growth kinetics.

    Myocardial p-I 123 -Phenylpentadecanoic acid (I-PPA) turnover has been evaluated in patients with coronary artery (CAD) and valvular heart disease (VHD) and normal coronaries. After intracoronary I-PPA application myocardial extraction fractions of 25 - 30% of applied radioactivity were observed in patients with VHD, compared to 8 - 35% in patients with CAD. 2 - 3 component myocardial radioactivity clearance with half times of 0.24 - 0.5, 6 - 10 and 40 - 60 min were observed in patients with VHD. Patients with CAD showed monoexponential myocardial radioactivity clearance with half times of 26 - 67 min. After peripheral i.v. tracer application myocardial segments supplied by coronary arteries with 80 - 100% stenosis showed clearly reduced tracer uptake and prolonged elimination half times. Combined evaluation of I-PPA uptake and turnover clearly separated normally perfused myocardial segments from those supplied by coronary arteries with 80 - 100% stenosis. (Author)

    Proton pump inhibitors (PPIs) are among the commonest drugs used nowadays. The aim of our study was to analyze prolonged utilization of proton pump inhibitors in medical therapy of patients with ischemic and valvular heart disease. Secondly, profile of utilization was scrutinized to patient characteristics and type of cardiovascular treatments. The study included consecutive patients scheduled for cardiovascular rehabilitation 2-6months after index cardiovascular treatment. Two hundred ninety-four patients (n=294/604; 48.7%) have been using proton pump inhibitor in their therapy after index cardiovascular treatment. Cardiovascular treatments were powerfully connected with utilization of PPIs; surgery 5.77 (95%-confidence intervals [CI]: 4.05-8.22; pvalvular heart disease utilized proton pump inhibitor in prolonged courses. Prolonged courses of PPIs were connected with existence and worsening of red blood count indexes, older age, lesser weight of patients and underutilization of cardioprotective drugs.

    Tricuspid regurgitation (TR) is a very frequent manifestation of valvular heart disease. It may be due to the primary involvement of the valve or secondary to pulmonary hypertension or to the left-sided heart valve disease (most commonly rheumatic and involving the mitral valve). The pathophysiology of secondary TR is complex and is intrinsically connected to the anatomy and function of the right ventricle. A systematic multimodality approach to diagnosis and assessment (based not only on the severity of the TR but also on the assessment of annular size, RV function and degree of pulmonary hypertension) is, therefore, essential. Once considered non-important, treatment of secondary TR is currently viewed as an essential concomitant procedure at the time of mitral (and, less frequently, aortic valve) surgery. Although the indications for surgical management of severe TR are now generally accepted (Class I), controversy persists concerning the role of intervention for moderate TR. However, there is a trend for intervention in this setting, especially at the time of surgery for left-sided heart valve disease and/or in patients with significant tricuspid annular dilatation (Class IIa). Currently, surgery remains the best approach for the interventional treatment of TR. Percutaneous tricuspid valve intervention (both repair and replacement) is still in its infancy but may become a reliable option in future, especially for high-risk patients with isolated primary TR or with secondary TR related to advanced left-sided heart valve disease. © The Author 2017.

    Objective Plasma brain natriuretic peptide (BNP) concentrations predict prognosis in patients with valvular heart disease (VHD), but it is unclear whether this directly relates to disease severity. We assessed the relationship between BNP and echocardiographic measures of disease severity in patients with VHD. Methods Plasma BNP concentrations were measured in patients with normal left ventricular (LV) systolic function and isolated VHD (mitral regurgitation (MR), n=33; aortic regurgitation (AR), n=39; aortic stenosis (AS), n=34; mitral stenosis (MS), n=30), and age-matched and sex-matched controls (n=39) immediately prior to exercise stress echocardiography. Results Compared with controls, patients with VHD had elevated plasma BNP concentrations (MR median 35 (IQR 23–52), AR 34 (22–45), AS 31 (22–60), MS 58 (34–90); controls 24 (16–33) pg/mL; p<0.01 for all). LV end diastolic volume index varied by valve lesion; (MR (mean 77±14), AR (91±28), AS (50±17), MS (43±11), controls (52±13) mL/m2; p<0.0001). There were no associations between LV volume and BNP. Left atrial (LA) area index varied (MR (18±4 cm2/m2), AR (12±2), AS (11±3), MS (19±6), controls (11±2); p<0.0001), but correlated with plasma BNP concentrations: MR (r=0.42, p=0.02), MS (r=0.86, p<0.0001), AR (r=0.53, p=0.001), AS (r=0.52, p=0.002). Higher plasma BNP concentrations were associated with increased pulmonary artery pressure and reduced exercise capacity. Despite adverse cardiac remodelling, 81 (60%) patients had a BNP concentration within the normal range. Conclusions Despite LV remodelling, plasma BNP concentrations are often normal in patients with VHD. Conversely, mild elevations of BNP occur with LA dilatation in the presence of normal LV. Plasma BNP concentrations should be interpreted with caution when assessing patients with VHD. PMID:27175283

    The aims of this study were to compare the level of posttraumatic stress disorder between adults with and without congenital heart disease, and to examine the correlates of posttraumatic stress disorder (e.g., sociodemographics). Cross-sectional. Two university-affiliated heart hospitals in Tehran, Iran. A sample of 347 adults with congenital heart disease aged 18-64 years (52% women), and 353 adults without congenital heart disease matched by sex and age (±2 years) was recruited. The PTSD Scale: Self-report version was used to assess the diagnosis and severity of posttraumatic stress disorder. Hierarchical multivariate logistic regression analyses were performed to explore correlates of likely posttraumatic stress disorder diagnosis among each group of participants. The posttraumatic stress disorder in the patients was comparable to those of the control group, except for increased arousal (P = .027) which was scored higher among the patients. Over 52% of adults with congenital heart disease met the criteria for a likely posttraumatic stress disorder diagnosis compared with 48% of adults without congenital heart disease. The regression analyses among patients revealed that elevated depressive symptoms (OR = 1.27) and a positive history of cardiac surgery (OR = 2.02) were significantly associated with posttraumatic stress disorder. The model could explain 29% of the variance in posttraumatic stress disorder. The high and comparable prevalence of posttraumatic stress disorder among patients and nonpatients highlight the significance of the context in which adults with congenital heart disease may face other/additional stressors than disease-related ones, an issue that clinicians need also take into account. Furthermore, the association of posttraumatic stress disorder with elevated depressive symptoms warrant a comprehensive psychological assessment and management of adults with congenital heart disease, in particular among those with a history of

    Background Prior studies on the depression-heart disease association have not usually used diagnostic measures of depression, nor taken other mental disorders into consideration. As a result, it is not clear whether the association between depression and heart disease onset reflects a specific association, or the comorbidity between depression and other mental disorders. Additionally, the relative magnitude of associations of a range of mental disorders with heart disease onset is unknown. Methods Face-to-face household surveys were conducted in 19 countries (n=52,095; person years=2,141,194). The Composite International Diagnostic Interview retrospectively assessed lifetime prevalence and age at onset of 16 DSM-IV mental disorders. Heart disease was indicated by self-report of physician’s diagnosis, or self-report of heart attack, together with their timing (year). Survival analyses estimated associations between first onset of mental disorders and subsequent heart disease onset. Results After comorbidity adjustment, depression, panic disorder, specific phobia, post-traumatic stress disorder and alcohol use disorders were associated with heart disease onset (ORs 1.3–1.6). Increasing number of mental disorders was associated with heart disease in a dose-response fashion. Mood disorders and alcohol abuse were more strongly associated with earlier onset than later onset heart disease. Associations did not vary by gender. Conclusions Depression, anxiety and alcohol use disorders were significantly associated with heart disease onset; depression was the weakest predictor. If confirmed in future prospective studies, the breadth of psychopathology’s links with heart disease onset has substantial clinical and public health implications. PMID:23993321

    Valvular heart disease (VHD) and atrial fibrillation (AF) often coexist. Phase III trials comparing non-vitamin K antagonist oral anticoagulants (NOACs) with warfarin excluded patients with moderate/severe mitral stenosis or mechanical heart valves, but variably included patients with other VHD and valve surgeries. This study aimed to determine relative safety and efficacy of NOACs in patients with VHD. We performed a meta-analysis of the 4 phase III AF trials of the currently available NOACs versus warfarin in patients with coexisting VHD to assess pooled estimates of relative risk (RR) and 95% confidence intervals (CIs) for stroke/systemic embolic events (SSEE), major bleeding, intracranial hemorrhage (ICH), and all-cause death. Compared with warfarin, the rate of SSEE in patients treated with higher-dose NOACs was lower and consistent among 13,585 patients with (RR: 0.70; 95% CI: 0.58 to 0.86) or 58,098 without VHD (RR: 0.84; 95% CI: 0.75 to 0.95; interaction p = 0.13). Major bleeding in patients on higher-dose NOACs versus warfarin was similar and consistent among patients with (RR: 0.93; 95% CI: 0.68 to 1.27) or without VHD (RR: 0.85; 95% CI: 0.70 to 1.02; interaction p = 0.63 for VHD/no-VHD difference). Intracranial hemorrhage was lower with higher-dose NOACs than with warfarin irrespective of VHD (RR: 0.47; 95% CI: 0.24 to 0.93, and 0.49; 95% CI: 0.41 to 059, respectively; interaction p = 0.91). No protective effect of higher-dose NOACs in preventing all-cause death seemed to be present in patients with VHD versus without VHD (RR:1.01; 95% CI: 0.90 to 1.14 vs. RR: 0.88; 95% CI: 0.82 to 0.94, respectively; interaction p = 0.03). High-dose NOACs provide overall efficacy and safety similar in AF patients with or without VHD. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

    Few centers for open heart surgery (OHS) are in Sub-Saharan Africa. Lack of OHS results is also noted. By reporting our African experience on OHS, the aim of this study was to fill the gap. It is a retrospective study on 2,612 patients who were subject to an OHS between 1978 and 2013. Data were collected from demographical, clinical, investigative studies, surgical and outcomes parameters. There were 1,475 cases of rheumatic heart diseases (RHD), 126 endomyocardial fibrosis (EMF), 741 congenital heart diseases (CHDs) and 270 various affections. Related to rheumatic valvular surgery we enumerated 1,175 monovalvular (mitral n=778, aortic n=336, tricuspid n=61); 280 bivalvular (mitral + aortic n=150, mitral + tricuspid n=130) and 20 trivalvular. For RHD, average age was 26±10.1 years (4-69 years) and 60% of our patients presented a functional class III or IV according to New York Heart Association (NYHA) classification. A total of 1,481 valvular replacements (bioprostheses n=489, mechanical prostheses n=992) and 445 valvular repair were carried out with a global and late mortality surgery respectively at 7% and 8%. One hundred and twenty-six [126] cases of EMF with right sided form 39, left sided form 40, and bilateral form 47 were colligated. Average age was 12±0.6 years (2-15 years). All patients with EMF underwent surgery; an endocardectomy in all patients combined with valvular reconstruction (n=36) or valvular replacement (n=90) was carried out with a hospital mortality at 16% (n=20). Concerning CHD, the most frequent were ventricular septal defect (VSD) (n=240), atrial septal defect (ASD) (n=200), partial atrio-ventricular sepal defect (n=30) and tetralogy of Fallot (T4F) (n=220), a total correction was performed for those CHD with an early mortality at 6.4% (n=44). OHS in Cote d'Ivoire was successfully performed in most of our patients, the spectrum of acquired valvular heart diseases and CHDs in our country is similar to others in Sub-Saharan Africa.

    2014-03-15

    Worldwide, the numbers of women who have a pre-existing cardiovascular disease or develop cardiac problems during pregnancy are increasing and, due to the lack of evidenced-based data, this provides challenges for the treating physician. Cardiovascular disease in pregnancy is a complex topic as women can present either pre- or post-partum, due to a pre-existing heart disease such as operated on or unoperated on congenital heart disease, valvular heart disease, chronic hypertension, or familial dilated cardiomyopathy. Women often present with symptoms and signs of acute heart failure. On the other hand, there are diseases which are directly related to pregnancy, such as hypertensive disorders of pregnancy and peripartum cardiomyopathy, or where pregnancy increases risk of a disease as, for example, the risk of myocardial infarction. These diseases can have long-term implications to the life of the affected women and their families. There is, in particular, a paucity of data from developing countries of this unique disease pattern and its presentations. This review summarizes the current knowledge of the incidence and prevalence of pregnancy-related cardiovascular disease in women presenting pre- or post-partum.

    2017-05-12

    The present study was designed to investigate the role of selected essential and toxic metals in the onset/prognosis of valvular heart disease (VHD). Nitric acid-perchloric acid based wet digestion procedure was used for the quantification of the metals by flame atomic absorption spectrophotometry. Comparative appraisal of the data revealed that average levels of Cd, Co, Cr, Fe, K, Li, Mn and Zn were significantly higher in blood of VHD patients, while the average concentration of Ca was found at elevated level in controls (P < 0.05). However, Cu, Mg, Na, Sr and Pb depicted almost comparable levels in the blood of both donor groups. The correlation study revealed significantly different mutual associations among the metals in the blood of VHD patients compared with the controls. Multivariate statistical methods showed substantially divergent grouping of the metals for the patients and controls. Some significant differences in the metal concentrations were also observed with gender, abode, dietary/smoking habits and occupations of both donor groups. Overall, the study demonstrated that disproportions in the concentrations of essential/toxic metals in the blood are involved in pathogenesis of the disease.

  2. Orexin: a Missing Link Between Sleep Disorders and Heart Failure?

    2017-04-01

    Sleep disorders represent a significant comorbidity in the heart failure population, and there is mounting evidence that treatment of sleep disorders such as obstructive sleep apnea can significantly improve cardiac function. However, the link between these two disorders is still not entirely clear. Recently, a novel neurohormonal pathway has been elucidated involving signaling molecules now collectively known as the orexins, which have been implicated in regulating autonomic function during sleep/wake cycles. Further evidence has mounted that orexin signaling is deeply perturbed in the setting of sleep disorders, and furthermore that abnormal orexin signaling may be implicated in the pathology of heart failure. The orexin signaling pathway represents an enticing novel target for both the treatment of sleep disorders as well as heart failure, and may represent one facet of the "missing link" between these two prevalent and often comorbid diseases.

    Pediatric cardiac computed tomography (CT) is a noninvasive imaging modality used to clearly demonstrate the anatomical detail of congenital heart diseases. We investigated the impact of cardiac CT on the utilization of cardiac catheterization among children with congenital heart disease. The study sample consisted of 2648 cardiac CT and 3814 cardiac catheterization from 1999 to 2009 for congenital heart diseases. Diagnoses were categorized into 11 disease groups. The numbers of examination, according to the different modalities, were compared using temporal trend analyses. The estimated effective radiation doses (mSv) of CT and catheterization were calculated and compared. The number of CT scans and interventional catheterizations had a slight annual increase of 1.2% and 2.7%, respectively, whereas that of diagnostic catheterization decreased by 6.2% per year. Disease groups fell into two categories according to utilization trend differences between CT and diagnostic catheterization. The increased use of CT reduces the need for diagnostic catheterization in patients with atrioventricular connection disorder, coronary arterial disorder, great vessel disorder, septal disorder, tetralogy of Fallot, and ventriculoarterial connection disorder. Clinicians choose either catheterization or CT, or both examinations, depending on clinical conditions, in patients with semilunar valvular disorder, heterotaxy, myocardial disorder, pericardial disorder, and pulmonary vein disorder. The radiation dose of CT was lower than that of diagnostic cardiac catheterization in all age groups. The use of noninvasive CT in children with selected heart conditions might reduce the use of diagnostic cardiac catheterization. This may release time and facilities within the catheterization laboratory to meet the increasing demand for cardiac interventions. Copyright © 2014. Published by Elsevier B.V.

    The interrelationship between the etiology of pleural effusion and the side of its occurrence has been a subject of clinical interest for many years. It has often been stated that pleural effusion caused by congestive heart failure tends to occur on the right side. However, some authors contended that such a side proclivity is not reliable. In the present study, the authors investigated the laterally of effusion caused by various cardiovascular diseases complicated by heart failure. We reviewed the chest X-ray films and clinical records of 68 patients with proven pleural effusion resulted from heart failure. 1. There were 34 men and 34 women with the age ranging from 10 to 84 years with the mean of 59. 2. The diagnoses were rheumatic heart disease (2 patients), coronary heart disease (10 patients), hypertensive heart disease (8 patients), mitral valvular disease (18 patients), aortic valvular disease (3 patients), and miscellaneous (27 patients). 3. 34 patients had unilateral pleural effusion, 25 and 9, right and left, respectively. Of the 34 patients with bilateral effusion, 13 patients had predominantly right-sided effusion, 5 patients had predominantly left-sided effusion and 16 patients had evenly distributed bilateral effusion. Thus, 55.8% of effusion was right-sided

    Hirschsprung's disease (HD) occurs as an isolated phenotype in 70% of infants and is associated with additional congenital anomalies or syndromes in approximately 30% of patients. The cardiac development depends on neural crest cell proliferation and is closely related to the formation of the enteric nervous system. HD associated with congenital heart disease (CHD) has been reported in 5-8% of cases, with septation defects being the most frequently recorded abnormalities. However, the prevalence of HD associated with CHD in infants with syndromic disorders is not well documented. This systematic review was designed to determine the prevalence of CHD in syndromic HD. A systematic review of the literature using the keywords "Hirschsprung's disease", "aganglionosis", "congenital megacolon", "congenital heart disease" and "congenital heart defect" was performed. Resulting publications were reviewed for epidemiology and morbidity. Reference lists were screened for additional relevant studies. A total of fifty-two publications from 1963 to 2014 reported data on infants with HD associated with CHD. The overall reported prevalence of HD associated with CHD in infants without chromosomal disorders was 3%. In infants with syndromic disorders, the overall prevalence of HD associated with CHD ranged from 20 to 80 % (overall prevalence 51%). Septation defects were recorded in 57% (atrial septal defects in 29%, ventricular septal defects in 32%), a patent ductus arteriosus in 39%, vascular abnormalities in 16%, valvular heart defects in 4% and Tetralogy of Fallot in 7%. The prevalence of HD associated with CHD is much higher in infants with chromosomal disorders compared to infants without associated syndromes. A routine echocardiogram should be performed in all infants with syndromic HD to exclude cardiac abnormalities.

    There are few quantitative data on the extent or mechanism of pulmonary artery catheter (PAC)-induced valvular dysfunction. We hypothesized that PACs cause or worsen tricuspid and pulmonic valvular regurgitation, and tested this hypothesis by using transesophageal echocardiography. In 54 anesthetized adult patients, we measured color Doppler jet areas of tricuspid regurgitation (TR) in two planes (midesophageal [ME] 4-chamber and right ventricular inflow-outflow views) and pulmonic insufficiency (PI) in one plane (ME aortic valve long-axis view), both before and after we advanced a PAC into the pulmonary artery. Regurgitant jet areas and hemodynamic measurements were compared by using paired t-test. There were no significant changes in blood pressure or heart rate after passage of the PAC. After PAC placement, the mean PI jet area was not significantly increased. The mean TR jet area increased significantly in the right ventricular inflow-outflow view (+0.37 +/- 0.11 cm(2)) (P = 0.0014), but did not increase at the ME 4-chamber view. Seventeen percent of patients had an increase in TR jet area > or =1 cm(2); 8% of patients had an increase in PI jet area >/=1 cm(2). In patients without pulmonic or tricuspid valvular pathology, placement of a pulmonary artery catheter (PAC) worsened tricuspid regurgitation, which is consistently visualized in the right ventricular inflow-outflow view, and often not seen in the midesophageal 4-chamber view. This is consistent with malcoaptation of the anterior and posterior leaflets. PAC-induced pulmonic insufficiency was rarely detected in the midesophageal aortic valve long-axis view. We conclude that a PAC is very unlikely to be the sole cause of severe tricuspid regurgitation or pulmonic insufficiency.

    Background It is conceivable that contemporary valvular heart disease (VHD) is affected largely by an age-dependent atherosclerotic process, which is similar to that observed in coronary artery disease (CAD). However, a comorbid condition of VHD and CAD has not been precisely examined. The first objective of this study was to examine a possible comorbid condition. Provided that there is no comorbidity, the second objective was to search for the possible reasons by using conventional risk factors and plasma B-type natriuretic peptide (BNP) because BNP has a potentiality to suppress atherosclerotic development. Methods The study population consisted of 3,457 patients consecutively admitted to our institution. The possible comorbid condition of VHD and CAD and the factors that influence the comorbidity were examined by covariance structure analysis and multivariate analysis. Results The distribution of the patients with VHD and those with CAD in the histograms showed that the incidence of VHD and the severity of CAD rose with seniority in appearance. The real statistical analysis was planned by covariance structure analysis. The current path model revealed that aging was associated with VHD and CAD severity (P < 0.001 for each); however, as a notable result, there was an inverse association regarding the comorbid condition between VHD and CAD (Correlation coefficient [β]: -0.121, P < 0.001). As the second objective, to clarify the factors leading to this inverse association, the contribution of conventional risk factors, such as age, gender, hypertension, smoking, diabetes, obesity and dyslipidemia, to VHD and CAD were examined by multivariate analysis. However, these factors did not exert an opposing effect on VHD and CAD, and the inverse association defied explanation. Since different pathological mechanisms may contribute to the formation of VHD and CAD, a differentially proposed path model using plasma BNP revealed that an increase in plasma BNP being drawn by

    Dynamic MR images were obtained utilizing a repetition time of 21 msec, a 30-degree flip angle, and 12-msec gradient refocused echoes. Images were ECG-triggered and constructed at 16 images per cardiac cycle. To assess the sensitivity of dynamic MR imaging of valvular regurgitation, 17 patients were so examined and results were compared with results of echocardiography or cardiac catheterization. Mitral and tricuspid valves were well visualized in all patients. Regurgitation was demonstrated in 14 cases as an area of decreased signal extending from the valve into the regurgitant chamber, corresponding in time to ventricular systole for mitral and tricuspid regurgitation and diastole for aortic insufficiency. There were no false-negative MR imaging studies

    In order to evaluate the clinical value and limitation of magnetic resonance imaging (MRI) for detection and quantification of valvular regurgitation, 98 patients with various cardiac diseases were studied by cine MRI and the results were compared with contrast angiography and doppler color-flow imaging. Cine MRI was carried out using FLASH (fast low angle shot) which employs TE of 10∼20 msec and TR of 30∼40 msec. 22 transverse tomograms per cardiac cycle with a slice thickness of 10 mm were obtained at the level of atrium and ventricle. The jet of valvular regurgitation was easily seen as a discrete are of low signal with cine MRI. Identification of the regurgitation and its severity were visually evaluated based on the relative size of the regurgitant jet from the incompetent valve orifice. Using contrast angiography as a gold standard, the sensitivity of cine MRI for detecting mitral regurgitation was 83% and was 94% for aortic regurgitation, with the specificity of 82% and 100%, respectively. For mitral requrgitation and aortic regurgitation, evaluation by cine MRI and severity agreed well with contrast angiography. By the comparative study with doppler color-flow imaging, relatively good agreement was found between the two methods in detection and quantitative evaluation of valvular regurgitation in any of four valves. Cine MRI was suggested to be useful for both the detection and semiquantification of valvular regurgitation in generally, but its clinical limitation at this point was also found because, 1)its images are not acquired in real times, as in contrast angiography or doppler color-flow imaging, but are compiled from the cumulative information from 128 heart beats, 2)the evaluation of regurgitation is made from only two-dimensional transverse tomograms.

    Full Text Available Aim. To study effect of diuretic therapy with furosemide and torasemide on heart rate variability (HRV and frequency of ventriclar rhythm disorders in patients with chronic heart failure (CHF complicating ischemic heart disease (IHD.Material and methods. Patients (n=107 with CHF III-IV functional class (NYHA complicating IHD were examined. The first group of patients received furosemide, 20-60 mg QD (n=52, the second group received torasemide, 5-20 mg QD (n=55. Analysis of heart rhythm disorders and the basic HRV indicators was performed by ECG 10-minute recordings initially and after 10 days of therapy.Results. Decrease in time and spectral HRV parameters and increase in daily number of ventricular extrasystoles was found in furosemide treated patients. Improvement of HRV parameters and reduction of daily number of ventricular rhythm disorders was found torasemide treated patients.Conclusion. Torasemide therapy improves an autonomic regulation of heart rhythm and leads to the reduction of ventricular heart rhythm disorders in patients with CHF complicating IHD.

    1993-01-01

    Left ventricular (LV) diastolic functions in 23 patients with aortic regurgitation (AR) and 22 patients with mitral regurgitation (MR) were evaluated by gated blood pool scintigraphy. LV myocardial biopsy was performed during open heart surgery, and LV myocardial ultrastructural changes were evaluated by electron microscope. Correlation between LV diastolic function and myocardial ultrastructural changes was examined. It was suggested that preoperative LV diastolic dysfunction occurred earlier than LV systolic dysfunction in patients with AR and MR. LV early diastolic dysfunction was especially significant in patients with AR. LV systolic function was significantly improved postoperatively compared with LV diastolic function in patients with AR and MR. It was suggested that LV interstitial fibrosis caused LV diastolic dysfunction in patients with AR and MR, and insufficiency of myocardial thickening as compensation in patients with MR. It was presumed that LV diastolic dysfunction was irreversible in patients with AR and MR in the distant postoperative period due to persistence of the preoperative myocardial ultrastructural change, e.g., interstitial fibrosis. These LV diastolic indices measured by gated pool scintigraphy were useful in predicting LV ultrastructural changes and postoperative LV dysfunction in patients with LV volume-overloaded valvular heart disease.

    Among the vascular involvements of Takayasu arteritis, a supra-valvular aortic stenosis has been reported very rarely. We report a case of surgically corrected, supra-valvular aortic stenosis caused by Takayasu arteritis. A 32-year-old female was diagnosed with supra-valvular aortic stenosis by transthoracic echocardiography for the evaluation of cardiac murmur with constitutional symptoms. Under the impression of non-familial sporadic type of supra-valvular aortic stenosis, surgical correction was performed. However, after 1 year from the operation, we could know the cause of her disease through the findings of computed tomographic aortography that Takayasu arteritis was suspected. Takayasu arteritis should be considered in adult female patients presenting supra-valvular aortic stenosis with constitutional symptoms, even if no typical features of vascular involvement.

    The present study deals with the plausible association between the trace elemental imbalances and the emergence of valvular heart disease (VHD). A total of 14 elements including Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Pb, Sr and Zn in the scalp hair of VHD patients and healthy donors were analysed by flame atomic absorption spectrophometry employing wet acid digestion methodology. Median levels of Cu, Fe, Mg, Mn and Sr in the scalp hair of patients were significantly higher compared to those of the healthy donors, while the median concentrations of K and Na were found to be considerably higher in the scalp hair of the healthy donors. In addition, substantially elevated Cu/Zn value in patients indicated the prevalence of inflammatory processes inside the body. The correlation coefficients among the elements in the hair of VHD patients were significantly diverse compared to those of the healthy donors. Multivariate statistical methods showed noticeably dissimilar apportionment of the elements in the two groups. Variations in the elemental levels were also observed with gender, habitat, dietary/smoking habits and occupations of both donor groups. Overall, the study revealed significant imbalances among the essential and toxic elements in the scalp hair of VHD patients compared to those of the healthy subjects.

    Full Text Available En los últimos 15 años se han desarrollado nuevas tecnologías en cirugía cardíaca para evitar la incisión más frecuente, la esternotomía media, o la circulación extracorpórea, intentando así realizar una cirugía menos invasora. Entre estas técnicas se sitúa la cirugía mediante puertos o Heart Port™. Los principales beneficios de esta técnica radican, entre otros, en la disminución del traumatismo quirúrgico, lo que se asocia a una disminución del dolor postoperatorio y de la estancia hospitalaria así como a una mayor satisfacción de los pacientes desde un punto de vista estético. La cirugía valvular mitral y/o tricúspide de mínimo acceso es, en la actualidad, una técnica reproducible y segura, que puede desarrollarse con una morbimortalidad semejante a la técnica convencional, considerándose a día de hoy una opción válida de tratamiento para cualquier paciente sometido a una cirugía de sustitución o reparación mitral o tricúspide. En este artículo se describen las peculiaridades de la técnica quirúrgica y se analizan los resultados en cuanto a morbimortalidad postoperatoria de las diferentes series publicadas.

    Full Text Available Liver congestion due to heart failure in patients with valvular heart disease (VHD can result in an overestimate of the liver stiffness (LS as assessed by transient elastography (TE. This prospective pilot study investigated the dynamics of LS during the perioperative valve operation period.Thirty-two patients who underwent a valve operation (case and 12 who underwent a varicose vein operation (control were prospectively enrolled. LS and cardiologic parameters at three time points [baseline, post-operative day (POD7, and POD90] were collected.LS at three time points were consistently higher in the case group than those in the control group, although all participants did not show evidence of underlying chronic liver disease (all P<0.05. In the case group, LS at POD7 increased slightly from the LS at baseline (median 7.9→8.4 kPa, P = 0.816, whereas LS at POD90 decreased significantly from the LS at POD7 (median 8.4→6.0 kPa; P = 0.026. LS was significantly correlated with N-terminal-pro brain natriuretic peptide (NT-proBNP (ρ = 0.412, left ventricular ejection fraction (ρ = -0.494, and central venous pressure during the operation (ρ = 0.555 at baseline (all P<0.05.

However, LS can be dynamically reversed during the perioperative period reflecting the restoration of cardiac function after a successful operation.

Health-related QoL was evaluated using the Short-Form 36 Health Survey (SF-36). Of the 258 participating patients, 24 (9.3%) fulfilled diagnostic criteria for panic disorder. Seven of these (29.2%) were diagnosed with comorbid anxiety disorders, 11 (47.3%) were diagnosed with comorbid depressive disorder, and 5 (20.8%) were diagnosed with other anxiety disorders and any depressive disorder. Female gender [odds ratio (OR)=3.1; 95% confidence interval (95% CI)=1.2-7.8; P=.02] and a lower level of education (OR=0.3; 95% CI=0.1-0.9; P=.04) were associated with the presence of panic disorder. In patients with panic disorder, QoL was significantly more restricted on all subscales of the SF-36 as compared to those without panic disorder, even when age, gender, and NYHA functional class were controlled for (P=.05 to <.01). Approximately 1 of 10 patients with CHF suffers from panic disorder, many of whom also have additional anxiety or depressive comorbid disorders. Female gender and a low level of education are positively associated with the presence of panic disorder. QoL is severely limited by the presence of panic disorder. Diagnosis of mental disorders and treatment offers for affected patients should be available in patient care.

    Left ventriculography with RAO projection gives many information about the states of mitral apparatus and of left ventricular function. The knowledge about these are very important to determination of performance, time and method of cardiac surgery in mitral valvular heart diseases. 20 patients of mitral valvular heart disease were studied with left ventriculographies in RAO projection which were taken before open heart surgery at department of radiology, National Medical Center during 1976 to June 1980, Comparing with operative findings and pathologic specimens. The results are as follows; 1. Poor motilities and irregularities of mitral valves which were visible above the fulcrum, and irregularities and severe retraction of the fornix during left ventricular systolic phases on left ventriculographies were compatible to the stage III by Sellers' classification of mitral valvular stenosis on operative findings. Mild degree of irregularities and restriction with smooth fornix suggested the stage I. The findings between these two, the stage II. 2. MI group showed left ventricular dilation without hypertrophy, MS group, no significant effect on LV, Ao group, enlargement with hypertrophy. 3. In Ms and MI groups, ejection fraction were relatively well preserved until grade I-II of NYHA Classification. But grade III-IV revealed decreased ejection fraction. E. F. was below 0.55 in 86% of grade III-IV. In Ao group, grade IV showed well preservation of E. F. 4.

    Cardiac auscultation is a key clinical skill, particularly for the diagnosis of valvular heart disease (VHD). However, its utility has declined due to the widespread availability of echocardiography and diminishing emphasis on the importance of clinical examination. We aim to determine the contemporary accuracy of auscultation for diagnosing VHD in primary care. Cardiac auscultation was undertaken by one of two experienced general practitioners (primary care/family doctors) in a subset of 251 asymptomatic participants aged >65 years undergoing echocardiography within a large community-based screening study of subjects with no known VHD. Investigators were blinded to the echocardiographic findings. Newly detected VHD was classified as mild (mild regurgitation of any valve or aortic sclerosis) or significant (at least moderate regurgitation or mild stenosis of any valve). Newly identified VHD was common, with mild disease in 170/251 participants (68%) and significant disease in 36/251 (14%). The sensitivity of auscultation was low for the diagnosis of mild VHD (32%) but slightly higher for significant VHD (44%), with specificities of 67% and 69%, respectively. Likelihood ratios were not statistically significant for the diagnosis of either mild or significant VHD in the overall cohort, but showed possible value for auscultation in non-overweight subjects (body mass index auscultation has limited accuracy for the detection of VHD in asymptomatic patients and is a poor diagnostic screening tool in primary care, particularly for overweight subjects. Ensuring easy access to echocardiography in patients with symptoms suggesting VHD is likely to represent a better diagnostic strategy. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Vascular function is very important for maintaining circulation after cardiac surgery. Circulating microparticles (MPs) generated in various diseases play important roles in causing inflammation, coagulation, and vascular injury. However, the impact of MPs generated from patients who have valvular heart disease (VHD), before and after cardiac surgery, on vascular function remains unknown. This study is designed to investigate the impact of such MPs on vasodilation. Microparticles were isolated from age-matched healthy subjects and patients who had VHD, before cardiac surgery, and at 12 hours and 72 hours afterward. The number of MPs was measured and compared. Effects evaluated were of the impact of MPs on: vasodilation of mice aorta; the phosphorylation and expression of Akt, endothelial nitric oxide synthase (eNOS), protein kinase C-βII (PKC-βII), and p70 ribosomal protein S6 kinase (p70S6K); expression of caveolin-1; the association of eNOS with heat shock protein 90 (HSP90); and generation of nitric oxide and superoxide anion of human umbilical vein endothelial cells. Compared with the healthy subjects, VHD patients had significantly higher levels of circulating MPs and those MPs before cardiac surgery can: impair endothelium-dependent vasodilation; inhibit phosphorylation of Akt and eNOS; increase activation of PKC-βII and p70S6K; enhance expression of caveolin-1; reduce the association of HSP90 with eNOS; decrease nitric oxide production, and increase superoxide anion generation. These deleterious effects were even stronger in postoperative MPs. Our data demonstrate that MPs generated from VHD patients before and after cardiac surgery contributed to endothelial dysfunction, by uncoupling and inhibiting eNOS. Circulating MPs are potential therapeutic targets for the maintenance of vascular function postoperatively. Copyright © 2015 The American Association for Thoracic Surgery. Published by Elsevier Inc.

    Fixed pericardial tissue is commonly used for commercially available xenograft valve implants, and has proven durability, but lacks the capability to remodel and grow. Decellularized porcine pericardial tissue has the promise to outperform fixed tissue and remodel, but the decellularization process has been shown to damage the collagen structure and reduce mechanical integrity of the tissue. Therefore, a comparison of uniaxial tensile properties was performed on decellularized, decellularized-sterilized, fixed, and native porcine pericardial tissue, versus native valve leaflet cusps. The results of non-parametric analysis showed statistically significant differences (ptesting of the tissues showed no statistical difference between decellularized or decell-sterilized tissue compared to native cusps (p>0.05). SEM confirmed that valvular endothelial and interstitial cells colonized the decellularized pericardial surface when seeded and grown for 30 days in static culture. Collagen assays and TEM analysis showed limited reductions in collagen with processing; yet, GAG assays showed great reductions in the processed pericardium relative to native cusps. Decellularized pericardium had comparatively lower mechanical properties amongst the groups studied; yet, the stiffness was comparatively similar to the native cusps and demonstrated a lack of cytotoxicity. Suture retention, accelerated wear, and hydrodynamic testing of prototype decellularized and decell-sterilized valves showed positive functionality. Sterilized tissue could mimic valvular mechanical environment in vitro, therefore making it a viable potential candidate for off-the-shelf tissue engineered valvular applications.

    During the 3rd trimester of pregnancy, 26 women with aortic or mitral valve disease (II class NYHA) have undergone bedside right heart catheterization. Total pulmonary resistances (RPT) have been studied in supine (DS) and lateral (DL) decubitus. The results are compared with those of 7 normal women. It is known that the change from the supine to the lateral posture increases venous return (and cardiac output) by removing the compression which the pregnant uterus causes to the inferior vena cava. This is achieved without increasing the mean pulmonary pressure (PPM) and total pulmonary resistances (RPT); women with mitral and aortic stenosis have little or no increase of cardiac output but always a marked increase of PPM and RPT; the response in patients with aortic and mitral incompetence is closer to normal; an intermediate response was observed in patients with a mitral stenosis and insufficiency. The valvular heart diseases with stenosis badly tolerate the increased cardiovascular burden of pregnancy and are unable to accommodate the increased venous return induced by postural changes, which induces marked elevation of pulmonary pressure and resistances.

    Acute kidney injury (AKI) is a common complication in cardiac surgery and coronary angiography, which worsens patients' prognosis. The diagnosis is based on the increase in serum creatinine, which is delayed. It is necessary to identify and validate new biomarkers that allow for early and effective interventions. To assess the sensitivity and specificity of neutrophil gelatinase-associated lipocalin in urine (uNGAL), interleukin-18 (IL-18) in urine and cystatin C in serum for the early detection of AKI in patients with acute coronary syndrome or heart failure, and who underwent cardiac surgery or catheterization. The study included 135 patients admitted to the intensive care unit for acute coronary syndrome or heart failure due to coronary or valvular pathology and who underwent coronary angiography or cardiac bypass surgery or valvular replacement. The biomarkers were determined 12 hours after surgery and serum creatinine was monitored during the next six days for the diagnosis of AKI. The area under the ROC curve (AUC) for NGAL was 0.983, and for cystatin C and IL-18 the AUCs were 0.869 and 0.727, respectively. At a cut-off of 31.9 ng/ml for uNGAL the sensitivity was 100% and the specificity was 91%. uNGAL is an early marker of AKI in patients with acute coronary syndrome or heart failure and undergoing cardiac surgery and coronary angiography, with a higher predictive value than cystatin C or IL-18.

    Full Text Available There is not too much success in the antioxidant treatment of heart deceases in humans. However a new approach is now developed that suggests that depending on their structures and concentrations antioxidants can exhibit much more complicated functions in many pathological disorders. It is now well established that physiological free radicals superoxide and nitric oxide together with their derivatives hydrogen peroxide and peroxynitrite (all are named reactive oxygen species (ROS and reactive nitrogen species (RNS play a more important role in heart diseases through their signaling functions. Correspondingly this work is dedicated to the consideration of damaging signaling by ROS and RNS in various heart and vascular disorders: heart failure (congestive heart failure or CHF, left ventricular hypertrophy (LVH, coronary heart disease, cardiac arrhythmias, and so forth. It will be demonstrated that ROS overproduction (oxidative stress is a main origin of the transformation of normal physiological signaling processes into the damaging ones. Furthermore the favorable effects of low/moderate oxidative stress through preconditioning mechanisms in ischemia/reperfusion will be considered. And in the last part we will discuss the possibility of efficient application of antioxidants and enzyme/gene inhibitors for the regulation of damaging ROS signaling in heart disorders.

    Despite a high incidence of calcific aortic valve disease in metabolic syndrome, there is little information about the fundamental metabolism of heart valves. Cell metabolism is a first responder to chemical and mechanical stimuli, but it is unknown how such signals employed in valve tissue engineering impact valvular interstitial cell (VIC) biology and valvular disease pathogenesis. In this study porcine aortic VICs were seeded into three-dimensional collagen gels and analysed for gel contraction, lactate production and glucose consumption in response to manipulation of metabolic substrates, including glucose, galactose, pyruvate and glutamine. Cell viability was also assessed in two-dimensional culture. We found that gel contraction was sensitive to metabolic manipulation, particularly in nutrient-depleted medium. Contraction was optimal at an intermediate glucose concentration (2 g l−1) with less contraction with excess (4.5 g l−1) or reduced glucose (1 g l−1). Substitution with galactose delayed contraction and decreased lactate production. In low sugar concentrations, pyruvate depletion reduced contraction. Glutamine depletion reduced cell metabolism and viability. Our results suggest that nutrient depletion and manipulation of metabolic substrates impacts the viability, metabolism and contractile behaviour of VICs. Particularly, hyperglycaemic conditions can reduce VIC interaction with and remodelling of the extracellular matrix. These results begin to link VIC metabolism and macroscopic behaviour such as cell–matrix interaction. PMID:25320066

Varios estudios han señalado la evidencia de estos hechos y de los posibles mecanismos por los cuales la afectación valvular ocurre. Existen hasta el momento pocas investigaciones sobre el asunto en pacientes con hiperprolactinemia, pero la mayoría de ellos indican que su empleo en este tipo de pacientes no produce afectación valvular clínicamente relevante, hecho que pudiera estar en relación con las dosis empleadas (como promedio 10 veces inferiores a las usadas en la enfermedad de Parkinson; sin embargo, se han detectado algunas anomalías subclínicas en el aparato valvular.

    Filamin A is an X-linked, ubiquitous actin-binding protein whose mutations are associated to multiple disorders with limited genotype-phenotype correlations. While gain-of-function mutations cause various bone dysplasias, loss-of-function variants are the most common cause of periventricular nodular heterotopias with variable soft connective tissue involvement, as well as X-linked cardiac valvular dystrophy (XCVD). The term "Ehlers-Danlos syndrome (EDS) with periventricular heterotopias" has been used in females with neurological, cardiovascular, integument and joint manifestations, but this nosology is still a matter of debate. We report the clinical and molecular update of an Italian family with an X-linked recessive soft connective tissue disorder and which was described, in 1975, as the first example of EDS type V of the Berlin nosology. The cutaneous phenotype of the index patient was close to classical EDS and all males died for a lethal cardiac valvular dystrophy. Whole exome sequencing identified the novel c.1829-1G>C splice variation in FLNA in two affected cousins. The nucleotide change was predicted to abolish the canonical splice acceptor site of exon 13 and to activate a cryptic acceptor site 15 bp downstream, leading to in frame deletion of five amino acid residues (p.Phe611_Gly615del). The predicted in frame deletion clusters with all the mutations previously identified in XCVD and falls within the N-terminus rod 1 domain of filamin A. Our findings expand the male-specific phenotype of FLNA mutations that now includes classical-like EDS with lethal cardiac valvular dystrophy, and offer further insights for the genotype-phenotype correlations within this spectrum. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

This paper provides echocardiographers with an overview of the modern role of TOE in the diagnosis and management of valvular disease. We describe how the introduction of 3D techniques has changed the detection and grading of valvular pathologies and concentrate on its role as a monitoring tool in interventional cardiology. In addition, we focus on the echocardiographic and Doppler techniques used in the assessment of prosthetic valves and provide guidance for the evaluation of prosthetic valves. Finally, we summarise quantitative methods used for the assessment of valvular stenosis and regurgitation and highlight the key areas where echocardiography remains superior over other novel imaging modalities.

    Introduction: Our aim was to perform a comparative study of short-term cardiovascular autonomic control in cardiac surgery patients who underwent coronary artery bypass grafting (CABG) or surgical correction of valvular heart disease (SCVHD ). Methods: The synchronous 15 minutes records of heart rate variability (HRV) and finger's photoplethysmographic waveform variability (PPGV) were performed in 42 cardiac surgery patients (12 women) aged 61.8 ± 8.6 years (mean ± standard deviation), who underwent CABG, and 36 patients (16 women) aged 54.2 ± 14.9 years, who underwent SCVHD , before surgery and in 5-7 days after surgery. Conventional time and frequency domain measures of HRV and index S of synchronization between the slow oscillations in PPGV and HRV were analyzed. We also calculated personal dynamics of these indices after surgery. Results: We found no differences ( Р > 0.05) in all studied autonomic indices (preoperative and post-surgery) between studied patients' groups, except for the preoperative heart rate, which was higher in patients who underwent SCVHD ( P = 0.013). We have shown a pronounced preoperative and post-surgery variability (magnitude of inter-quartile ranges) of all autonomic indices in studied patients. In the cluster analysis based on cardiovascular autonomic indices (preoperative and post-surgery), we divided all patients into two clusters (38 and 40 subjects) which did not differ in all clinical characteristics (except for the preoperative hematocrit, P = 0.038), index S, and all post-surgery HRV indices. First cluster (38 patients) had higher preoperative values of the HR, TP, HF, and HF%, and lower preoperative values of the LF% and LF/HF. Conclusion: The variability of cardiovascular autonomic indices in on-pump cardiac surgery patients (two characteristic clusters were identified based on preoperative indices) was not associated with their clinical characteristics and features of surgical procedure (including cardioplegia).

    Excess mortality from heart disease is observed in patients with severe mental disorder. This excess mortality may be rooted in adverse effects of pharmacological or psychotropic treatment, lifestyle factors, or inadequate somatic care. To examine whether persons with severe mental disorder, defined as persons admitted to a psychiatric hospital with bipolar affective disorder, schizoaffective disorder, or schizophrenia, are in contact with hospitals and undergoing invasive procedures for heart disease to the same degree as the nonpsychiatric general population, and to determine whether they have higher mortality rates of heart disease. A population-based cohort of 4.6 million persons born in Denmark was followed up from 1994 to 2007. Rates of mortality, somatic contacts, and invasive procedures were estimated by survival analysis. Incidence rate ratios of heart disease admissions and heart disease mortality as well as probability of invasive cardiac procedures. The incidence rate ratio of heart disease contacts in persons with severe mental disorder compared with the rate for the nonpsychiatric general population was only slightly increased, at 1.11 (95% confidence interval, 1.08-1.14). In contrast, their excess mortality rate ratio from heart disease was 2.90 (95% confidence interval, 2.71-3.10). Five years after the first contact for somatic heart disease, the risk of dying of heart disease was 8.26% for persons with severe mental disorder (aged mental disorder as compared with the nonpsychiatric general population (7.04% vs 12.27%, respectively). Individuals with severe mental disorder had only negligible excess rates of contact for heart disease. Given their excess mortality from heart disease and lower rates of invasive procedures after first contact, it would seem that the treatment for heart disease offered to these individuals in Denmark is neither sufficiently efficient nor sufficiently intensive. This undertreatment may explain part of their excess

    Full Text Available Calpain, calcineurin (CaN, and nuclear factor of activated T cell (NFAT play a key role in the development of atrial fibrillation. Patients with valvular heart disease (VHD are prone to develop atrial fibrillation (AF. Thus, our current study was aimed at investigating whether activation of calpain-CaN-NFAT pathway is associated with the incidence of AF in the patients with VHD and diabetes. The expressions of calpain 2 and alpha- and beta-isoforms of CaN catalytic subunit (CnA as well as NFAT-c3 and NFAT-c4 were quantified by quantitative reverse transcription-polymerase chain reaction in atrial tissues from 77 hospitalized patients with VHD and diabetes. The relevant protein content was measured by Western blot and calpain 2 in human atrium was localized by immunohistochemistry. We found that the expressions of calpain 2, CnA alpha and CnA beta, and NFAT-c3 but not NFAT-c4 were significantly elevated in the samples from patients with AF compared to those with sinus rhythm (SR. Elevated protein levels of calpain 2 and CnA were observed in patients with AF, and so was the enhanced localization of calpain 2. We thereby concluded that CaN together with its upstream molecule, calpain 2, and its downstream effector, NFAT-c3, might contribute to the development of AF in patients with VHD and diabetes.

  10. Reduced heart rate variability in social anxiety disorder: associations with gender and symptom severity.

    Directory of Open Access Journals (Sweden)

    Gail A Alvares

    Full Text Available BACKGROUND: Polyvagal theory emphasizes that autonomic nervous system functioning plays a key role in social behavior and emotion. The theory predicts that psychiatric disorders of social dysfunction are associated with reduced heart rate variability, an index of autonomic control, as well as social inhibition and avoidance. The purpose of this study was to examine whether heart rate variability was reduced in treatment-seeking patients diagnosed with social anxiety disorder, a disorder characterized by social fear and avoidance. METHODS: Social anxiety patients (n = 53 were recruited prior to receiving psychological therapy. Healthy volunteers were recruited through the University of Sydney and the general community and were matched by gender and age (n = 53. Heart rate variability was assessed during a five-minute recording at rest, with participants completing a range of self-report clinical symptom measures. RESULTS: Compared to controls, participants with social anxiety exhibited significant reductions across a number of heart rate variability measures. Reductions in heart rate variability were observed in females with social anxiety, compared to female controls, and in patients taking psychotropic medication compared to non-medicated patients. Finally, within the clinical group, we observed significant associations between reduced heart rate variability and increased social interaction anxiety, psychological distress, and harmful alcohol use. CONCLUSIONS: The results of this study confirm that social anxiety disorder is associated with reduced heart rate variability. Resting state heart rate variability may therefore be considered a marker for social approach-related motivation and capacity for social engagement. Additionally, heart rate variability may provide a useful biomarker to explain underlying difficulties with social approach, impaired stress regulation, and behavioral inhibition, especially in disorders associated with

    Full Text Available Non-valvular atrial fibrillation is a recognized risk factor for stroke and systemic embolism. It has been clearly established that warfarin reduces the risk of stroke and systemic embolism in persons with atrial fibrillation and additional risk factors for stroke. The use of warfarin, however, requires frequent monitoring, and there is great variability in patient response to warfarin. Warfarin interacts with several medications and foods. In addition, warfarin use portends a significant risk of bleeding. For these reasons, warfarin is frequently not prescribed to persons for whom the drug would provide a clear benefit. Over the past decade, attempts have been made to develop drugs that are at least as safe and effective as warfarin for the treatment of atrial fibrillation that do not require monitoring nor have as many interactions. Initial studies of compounds in this regard ultimately failed due to safety concerns, but over the past two years two novel agents have been approved by the United States Food and Drug Association for anticoagulation in non-valvular atrial fibrillation, another drug is under review, and additional compounds are being studied. This article will review the use of warfarin and these new agents in the treatment of non-valvular atrial fibrillation.

    Rare neuroendocrine tumours (NETs) that most commonly arise in the gastrointestinal tract can lead to carcinoid syndrome and carcinoid heart disease. Patients with carcinoid syndrome present with vasomotor changes, hypermotility of the gastrointestinal system, hypotension and bronchospasm. Medical therapy for carcinoid syndrome, typically with somatostatin analogues, can help control symptoms, inhibit tumour progression and prolong survival. Carcinoid heart disease occurs in more than 50% of these patients and is the initial presentation of carcinoid syndrome in up to 20% of patients. Carcinoid heart disease has characteristic findings of plaque-like deposits composed of smooth muscle cells, myofibroblasts, extracellular matrix and an overlying endothelial layer which can lead to valve dysfunction. Valvular dysfunction can lead to oedema, ascites and right-sided heart failure. Medical therapy of carcinoid heart disease is limited to symptom control and palliation. Valve surgery for carcinoid heart disease should be considered for symptomatic patients with controlled metastatic carcinoid syndrome. A multidisciplinary approach is needed to guide optimal management. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

    The aim of this study was to investigate usability of the Massardo method in calculating the left ventricular volume in patients with valvular defect. The group consisted of 21 patients with mitral defect. Left ventricular volumes obtained by contrast ventriculography were used for reference. The correlation coefficient between these two methods was 0.94, SEE=29 ml, V nucl =0.94 V c.vent +11. The end-systolic and end-diastolic outlines were marked manually. We concluded that the Massardo methods is an effective method of calculating the left ventricular volume also in group of patients with mitral defect. (author). 11 refs, 4 tabs

    Full Text Available Background. With modern medicine, many women after structural heart repair are deciding to experience pregnancy. There is a need for further study to identify normal echocardiographic parameters to better assess prosthetic valvular function in pregnancy. In addition, a multidisciplinary approach is essential in managing pregnant patients with complex cardiac conditions. Case. A 22-year-old nulliparous woman with an aortic valve replacement 18 months prior to her pregnancy presented to prenatal care at 20-week gestation. During her prenatal care, serial echocardiography showed a significant increase in the mean gradient across the prosthetic aortic valve. Multidisciplinary management and a serial echocardiography played an integral role in her care that resulted in a successful spontaneous vaginal delivery without complications. Conclusion. Further characterization of the normal echocardiographic parameters in pregnant patients with prosthetic valves is critical to optimize prenatal care for this patient population. This case report is novel in that serial echocardiograms were obtained throughout prenatal care, which showed significant changes across the prosthetic aortic valve. Teaching Points. (1 Further study is needed to identify normal echocardiographic parameters to best assess prosthetic valvular function in pregnancy. (2 Multidisciplinary management is encouraged to optimize prenatal care for women with prosthetic aortic valve replacements.

    Sensitivity and specificity of MR imaging for the evaluation of congenital heart disease was assessed in 51 patients (31 male and 20 female, aged 3-69 years), with a total of 115 congenital heart lesions. The true diagnosis was established by angiocardiography, catheterization, or surgery. Sensitivity at a specificity level of 90% was determined by means of receiver operating characteristic curves for great vessel relationships (100%), thoracic aorta anomalies (94%), atrial (91%) and ventricular (100%) septal defects, visceroatrial situs (100%), loop (100%), right ventricular outflow obstructions (95%), aortic valve (52%), mitral valve (62%), and tricuspid valve (76%). Spin-echo MR imaging is a reliable method for the noninvasive evaluation of congenital heart disease but is limited in the assessment of some valvular anomalies

    Full Text Available It has been demonstrated that high lipid content is accompanied with better course and surviving in chronic heart failure (CHF, which was called “the lipids paradox”. There are a very limited number of investigations which studied the relationship of lipid levels and indices of myocardial remodeling. Aim. To study the features of myocardial remodeling in patients with CHF with overweight and obesity depending on the total cholesterol (TCL and triglyceride (TG levels. Materials and methods. 230 patients were examined and analyzed 101 case histories of patients of with CHF of I–III functional class on the background of overweight and obesity I–III degree. CHF FC was determined by the classification of the New York Heart Association (NYHA. Normal, excess body weight and degree of abdominal obesity were detected by calculating the body mass index. Biochemical method was used to determine the blood levels of TCL and TG. The condition of myocardial remodeling was investigated by echocardiography. Results. It has been established, that smallest manifestation of myocardial remodeling was observed in patients with CHF on the background of overweight and obesity with high TCL level. The most severe manifestations of the heart chambers dilatation, left ventricle hypertrophy (LVH, and valvular functional changes characterized the patients with a low TCL concentration. High content of TG was also accompanied by a less pronounced cardiac remodeling, and the normal value of TG was characterized by more profound structural changes of theLV and valvular regurgitation. Conclusion. At CHF with overweight and obesity, lower TCL and TG levels are accompanied by more severe dilatation of the heart chambers and LVH, the prevalence of LVH eccentric type frequency, deeper functional valve disorders.

    Valvular heart disease is a leading cause of cardiovascular mortality, especially in China. More than a half of valvular heart diseases are caused by acute rheumatic fever. microRNA is involved in many physiological and pathological processes. However, the miRNA profile of the rheumatic valvular heart disease is unknown. This research is to discuss microRNAs and their target gene pathways involved in rheumatic heart valve disease. Serum miRNA from one healthy individual and four rheumatic heart disease patients were sequenced. Specific differentially expressed miRNAs were quantified by Q-PCR in 40 patients, with 20 low-to-moderate rheumatic mitral valve stenosis patients and 20 severe mitral valve stenosis patients. The target relationship between certain miRNA and predicted target genes were analysis by Luciferase reporter assay. The IL-1β and IL1R1 expression levels were analyzed by immunohistochemistry and western blot in the mitral valve from surgery of mitral valve replacement. The results showed that 13 and 91 miRNAs were commonly upregulated or downregulated in all four patients. Nine miRNAs, 1 upregulated and 8 downregulated, that had a similar fold change in all 4 patients were selected for quantitative PCR verification. The results showed similar results from miRNA sequencing. Within these 9 tested miRNAs, hsa-miR-205-3p and hsa-miR-3909 showed a low degree of dispersion between the members of each group. Hsa miR-205-3p and hsa-miR-3909 were predicted to target the 3'UTR of IL-1β and IL1R1 respectively. This was verified by luciferase reporter assays. Immunohistochemistry and Western blot results showed that the mitral valve from rheumatic valve heart disease showed higher levels of IL- 1β and IL1R1 expression compared with congenital heart valve disease. This suggested a difference between rheumatic heart valve disease and other types of heart valve diseases, with more inflammatory responses in the former. In the present study, by next generation

    Artificial heart valves are used in valvular heart diseases, but these valves have disadvantages that they cannot grow, repair and remodel. In current study, the strategies to development of in vitro cultured functional tissue by tissue engineering is available to heart valve disease. In the point of using viable autolougous cells, tissue engineered heart valves have some advantage to include that they can repair, remodel, and grow. Because heart valve is placed under the strong shear stress condition by pumping of heart, the durability of tissue-engineered heart valves is now questionable. The purpose of the study is to evaluate of the durability of tissue engineered heart valve with surface modified scaffolds under hemodynamic conditions

    Valvular heart disease is a life-threatening disease that afflicts millions of people worldwide and leads to approximately 250,000 valve repairs and/or replacements each year. Malfunction of a native valve impairs its efficient fluid mechanic/hemodynamic performance. Artificial heart valves have been used since 1960 to replace diseased native valves and have saved millions of lives. Unfortunately, despite four decades of use, these devices are less than ideal and lead to many complications. Many of these complications/problems are directly related to the fluid mechanics associated with the various mechanical and bioprosthetic valve designs. This review focuses on the state-of-the-art experimental and computational fluid mechanics of native and prosthetic heart valves in current clinical use. The fluid dynamic performance characteristics of caged-ball, tilting-disc, bileaflet mechanical valves and porcine and pericardial stented and nonstented bioprostheic valves are reviewed. Other issues related to heart valve performance, such as biomaterials, solid mechanics, tissue mechanics, and durability, are not addressed in this review.

    2013-01-01

    It is increasingly recognized that sleep-disordered breathing (SDB) is a common modifiable risk factor for cardiovascular disease with significant impact on morbidity and potentially mortality. SDB is highly prevalent in patients with systolic or diastolic heart failure. A high index of suspicion is necessary to diagnose SDB in patients with heart failure because the vast majority of affected patients do not report daytime symptoms. Recent clinical trials have demonstrated improvement in heart function, exercise tolerance, and quality of life after treatment of SDB in patients with heart failure. Accumulating evidence suggests that treatment of SDB should complement the established pharmacologic therapy for chronic heart failure. However, mortality benefit has yet to be demonstrated.

    Transcatheter management of valvular and structural heart disease is the most growing aspect of interventional cardiology. While the early experience was limited to patients who were not candidate for surgery, the continuous improvement in the efficacy and safety expanded its use to different degree depending on the procedure and the disease involved. The cost of these procedures is a major concern for health care in developed world. Cost-effectiveness of these transcatheter structural procedures varies depending on the procedure itself, the burden of the underlying disease, the feasibility and cost of both the Transcatheter and surgical procedures. In this review, we turn now to a specific discussion of the medical economics of percutaneous valvular and structural interventions.

    Cardiac computer tomography, echocardiography and radionuclide heart diagnosis are growing more and more important in cardiologic diagnostics. The value of the procedures was tested in 74 patients by combined application. Concordant morphologic findings could be obtained with echocardiography and cardiac computer tomography in the cases of chronic ischemic heart disease, cardiomyopathy and valvular heart diseases. Localized kinetic disturbances could be registered echocardiographically and by scintiscanning. The passableness of an aortocoronary bypass can be controlled first of all non-invasively by cardiac computer tomography. (author)

    2018-04-03

    This paper reviews treatment options for sleep disordered breathing (SDB) in patients with heart failure. We sought to identify therapies for SDB with the best evidence for long-term use in patients with heart failure and to minimize uncertainties in clinical practice by examining frequently discussed questions: what is the role of continuous positive airway pressure (CPAP) in patients with heart failure? Is adaptive servo-ventilation (ASV) safe in patients with heart failure? To what extent is SDB a modifiable risk factor? Consistent evidence has demonstrated that the development of SDB in patients with heart failure is a poor prognostic indicator and a risk factor for cardiovascular mortality. However, despite numerous available interventions for obstructive sleep apnea and central sleep apnea, it remains unclear what effect these therapies have on patients with heart failure. To date, all major randomized clinical trials have failed to demonstrate a survival benefit with SDB therapy and one major study investigating the use of adaptive servo-ventilation demonstrated harm. Significant questions persist regarding the management of SDB in patients with heart failure. Until appropriately powered trials identify a treatment modality that increases cardiovascular survival in patients with SDB and heart failure, a patient's heart failure management should remain the priority of medical care.

    1985-01-01

    The development of prosthetic heart valves in the late 1950s ushered in a new era in the treatment of heart disease. The radiologist has an important role to play preoperatively in the diagnosis of valvular heart disease. Radiology is valuable in identification of the implanted prosthetic valve and recognition of complications associated with valve implantation. Radiologists must be familiar with the imaging techniques best suited to evaluate the function of the valve prosthesis in question. In this chapter the authors discuss the radiographic approach to the evaluation of the status of patients for valve replacement and the imaging problems peculiar to the types of valves in current use. The relative value of plain-film radiography, fluoroscopy, videorecording and cinerecording, and aortography is addressed, as well as the potential value of magnetic resonance imaging and subsecond dynamic computed tomography

    Drug-induced valvular heart disease (VHD) is a serious side effect linked to long-term treatment with 5-hydroxytryptamine (serotonin) receptor 2B (5-HT 2B ) agonists. Safety assessment for off-target pharmacodynamic activity is a common approach used to screen drugs for this undesired property. Such studies include in vitro assays to determine whether the drug is a 5-HT 2B agonist, a necessary pharmacological property for development of VHD. Measures of in vitro binding affinity (IC 50 , K i ) or cellular functional activity (EC 50 ) are often compared to maximum therapeutic free plasma drug levels ( fC max ) from which safety margins (SMs) can be derived. However, there is no clear consensus on what constitutes an appropriate SM under various therapeutic conditions of use. The strengths and limitations of SM determinations and current risk assessment methodology are reviewed and evaluated. It is concluded that the use of SMs based on K i values, or those relative to serotonin (5-HT), appears to be a better predictor than the use of EC 50 or EC 50 /human fC max values for determining whether known 5-HT 2B agonists have resulted in VHD. It is hoped that such a discussion will improve efforts to reduce this preventable serious drug-induced toxicity from occurring and lead to more informed risk assessment strategies.

    It has been reported that 123 I-metaiodobenzylguanidine (MIBG) scintigraphy can predict the poor prognosis in patients with dilated cardiomyopathy (DCM). However, the prognostic significance of MIBG is still unknown in patients with other heart diseases. In this study, we compared the prognosis and MIBG findings in various heart diseases. Consecutive 565 patients undergoing MIBG scintigraphy were enrolled (392 men, 52±16 years). Indications were that 127 had ischemic heart disease (IHD), 120 DCM, 101 hypertrophic cardiomyopathy (HCM), 21 hypertensive heart disease (HHD), 58 volume-load valvular disease (VVD), 38 pressure-load valvular disease (PVD), and 101 ventricular tachycardia or fibrillation (VTF). Heart-to-mediastinum ratio (H/M) and washout rate (WR) of MIBG were evaluated. Cardiac events were defined as sudden cardiac death, heart failure, and acute ischemic event (follow-up, 22.7±17.0 months). A total of 106 cardiac events including 40 cardiac deaths occurred. Cox hazard model analysis showed that in the IHD, HCM, and DCM groups, H/M and WR were associated with cardiac death, but not in the HHD, PVD, VVD, or VTF groups. Only death and congestive heart failure (CHF) episodes were related to H/M and WR. On the other hand, fatal arrhythmia, myocardial infarction, or angina pectoris were not related to H/M and WR. The data indicated that WR or H/M may predict death and CHF but does not predict fatal arrhythmia or acute ischemic event. MIBG WR and H/M were associated with heart failure, sudden death, and cardiac death events, and were useful to predict the prognosis in DCM, HCM, and IHD. In contrast, fatal arrhythmia events were not associated with MIBG indices, and thus it does not appear to be useful in predicting cardiac events in patients with VTF. (author)

    About sixty subjects with normal heart or various cardiovascular diseases were examined with 0.35 or 1.5 T superconductive magnetic resonance imaging (MRI) system, and ECG-gated spin-echo multislice technique was used to evaluate cardiovascular anatomy. MRI accurately demonstrated ventricular wall thinning caused by myocardial infarction and asymmetric ventricular hypertrophy owing to cardiomyopathy. Rheumatic valvular thickening, congenital cardiac malformations, aortic aneurysm and dissection were also clearly demonstrated by gated MRI without the use of any contrast media. MRI was shown to be an excellent non-invasive imaging modality for evaluation of pathoanatomy of the heart and great vessels. (author)

    Based on transverse (TRN) and LV long axis (LAX) MR images of two cadaver hearts, three-dimensional (3-D) computer models of the connecting interface between remaining heart and total artificial heart, i.e., mitral and tricuspid valvular annuli (MVA and TVA), ascending aorta (Ao) and pulmonary artery (PA), were reconstructed to compare the shape and the size of MVA and those of TVA, the distance between the center of MVA and TVA (D G ), the angle between the plane of MVA and that of TVA (R T ), and the angles of Ao and PA, respectively, to the plane of MVA (R A , R P ), with those obtained in cast silicone models. It was found that based on LAX rather than TRN MR image, MVA and TVA might be more precisely reconstructed. The data obtained in 3-D images of MVA, TVA, Ao and PA based on silicone models of 32 hearts were as follows: D G (cm): 4.17±0.43, R T (degrees): 22.1±11.3, R A (degrees): 54.9±15.3, R P (degrees): 30.8±17.1.

    Cardiovascular complications represent the leading cause of morbidity and mortality in patients with Marfan syndrome. Here, we describe a unique case where a total artificial heart was implanted in a young Marfan syndrome woman. A 22-year-old postpartum African American female with Marfan syndrome developed multiple severe valve dysfunction and biventricular failure that was refractory to medical management. She previously had a Bentall procedure for Type A aortic dissection and repair of a Type B dissection. We implanted a total artificial heart with a good outcome. Total artificial heart is a durable option for severe biventricular failure and multiple valvular dysfunction as a bridge to transplant in a young patient with Marfan syndrome.

    Full Text Available Hemodynamic management aims to provide adequate tissue perfusion, which is often altered during cardiac surgery with cardiopulmonary bypass (CPB. We evaluated whether skin perfusion pressure (SPP can be used for monitoring of adequacy of tissue perfusion in patients undergoing valvular heart surgery. Seventy-two patients undergoing valve replacement were enrolled. SPP and serum lactate level were assessed after anaesthesia induction (baseline, during CPB, after CPB-off, end of surgery, arrival at intensive care unit, and postoperative 6 h. Lactate was further measured until postoperative 48 h. Association of SPP with lactate and 30-day morbidity comprising myocardial infarction, acute kidney injury, stroke, prolonged intubation, sternal infection, reoperation, and mortality was assessed. Among the lactate levels, postoperative 6 h peak value was most closely linked to composite of 30-day morbidity. The SPP value during CPB and its % change from the baseline value were significantly associated with the postoperative 6 h peak lactate (r = -0.26, P = 0.030 and r = 0.47, P = 0.001, respectively. Optimal cut-off of % decrease in SPP during CPB from baseline value for the postoperative 6 h hyperlactatemia was 48% (area under curve, 0.808; 95% confidence interval (CI, 0.652-0.963; P = 0.001. Decrease in SPP >48% during CPB from baseline value was associated with a 12.8-fold increased risk of composite endpoint of 30-day morbidity (95% CI, 1.48-111.42; P = 0.021 on multivariate logistic regression. Large decrease in SPP during CPB predicts postoperative 6 h hyperlactatemia and 30-day morbidity, which implicates a promising role of SPP monitoring in the achievement of optimal perfusion during CPB.

    OBJECTIVE: To determine whether cardiac computed tomography (MDCT) can differentiate between functional and valvular aetiologies of chronic mitral regurgitation (MR) compared with echocardiography (TTE). METHODS: Twenty-seven patients with functional or valvular MR diagnosed by TTE and 19 controls prospectively underwent cardiac MDCT. The morphological appearance of the mitral valve (MV) leaflets, MV geometry, MV leaflet angle, left ventricular (LV) sphericity and global\\/regional wall motion were analysed. The coronary arteries were evaluated for obstructive atherosclerosis. RESULTS: All control and MR cases were correctly identified by MDCT. Significant differences were detected between valvular and control groups for anterior leaflet length (30 +\\/- 7 mm vs. 22 +\\/- 4 mm, P < 0.02) and thickness (3.0 +\\/- 1 mm vs. 2.2 +\\/- 1 mm, P < 0.01). High-grade coronary stenosis was detected in all patients with functional MR compared with no controls (P < 0.001). Significant differences in those with\\/without MV prolapse were detected in MV tent area (-1.0 +\\/- 0.6 mm vs. 1.3 +\\/- 0.9 mm, P < 0.0001) and MV tent height (-0.7 +\\/- 0.3 mm vs. 0.8 +\\/- 0.8 mm, P < 0.0001). Posterior leaflet angle was significantly greater for functional MR (37.9 +\\/- 19.1 degrees vs. 22.9 +\\/- 14 degrees , P < 0.018) and less for valvular MR (0.6 +\\/- 35.5 degrees vs. 22.9 +\\/- 14 degrees, P < 0.017). Sensitivity, specificity, and positive and negative predictive values of MDCT were 100%, 95%, 96% and 100%. CONCLUSION: Cardiac MDCT allows the differentiation between functional and valvular causes of MR.

    Diseases of the heart and great vessels were diagnosed by CT through comparison of the pictures with that of control. Indications for CT included pericardiac diseases such as pericardial effusion, pericardiac cyst, pericardiac defect, pericardiac fat pad, and dilated or hypertrophic ventriculus. Of coronary artery diseases, myocardial infarction is the best indication for CT; and coronary artery calcification and coronary artery bypass graft for checking up the patency were also indications for this method. CT was useful for diagnosis of valvular diseases, especially mitral valve diseases, congenital heart diseases with structural abnormalities, abnormalities of the aorta and great veins, and of the pulmonary arteries and veins, and for follow-up of pulmonary congestion.

    Disorders of the heart valves constitute a considerable health problem and often require surgical intervention. Recently various approaches were published seeking to overcome the shortcomings of current clinical practice,that still relies on manually performed measurements for performance assessment. Clinical decisions are still based on generic information from clinical guidelines and publications and personal experience of clinicians. We present a framework for retrieval and decision support using learning based discriminative distance functions and visualization of patient similarity with relative neighborhood graphsbased on shape and derived features. We considered two learning based techniques, namely learning from equivalence constraints and the intrinsic Random Forest distance. The generic approach enables for learning arbitrary user-defined concepts of similarity depending on the application. This is demonstrated with the proposed applications, including automated diagnosis and interventional suitability classification, where classification rates of up to 88.9% and 85.9% could be observed on a set of valve models from 288 and 102 patients respectively.

    Since the amplitude value of a pixel is proportional to the stroke counts of the pixel, the total amplitude value of each ventricle would reflect its own stroke volume. Stroke count ratio (SCR) and ventricular amplitude ratio (VAR) values were simultaneously calculated and compared in 43 subjects, including 13 subjects with valvular regurgitation, after multigated equilibrium scintigraphy was performed. Mean values of SCR in 13 subjects with valvular regurgitation and 30 control subjects were 2.22+-1.11, 1.24+-0.41, respectively (p<0.005). Mean values of VAR were 2.52+-0.87, 1.36+-0.39, respectively (p<0.0005). The VAR method was independent of the tilting angles of the detector, and showed excellent intra-observer and inter-observer reproducibilities (r=0.95, r=0.91). The VAR method derived from the Fourier amplitude image is a noninvasive technique, is suitable for serial studies, and appears to be a relatively reliable means of assessing the severity of left-sided valvular regurgitation.

    Normal and calcified human valve cusps, coronary arteries, and aortae harbor spherical calcium phosphate microparticles of identical composition and crystallinity, and their role remains unknown. The objective was to examine the direct effects of isolated calcified particles on human valvular cells. Calcified particles were isolated from healthy and diseased aortae, characterized, quantitated, and applied to valvular endothelial cells (VECs) and interstitial cells (VICs). Cell differentiation, viability, and proliferation were analyzed. Particles were heterogeneous, differing in size and shape, and were crystallized as calcium phosphate. Diseased donors had significantly more calcified particles compared to healthy donors (Pinnocent bystanders but induce a phenotypical and pathological change of VECs and VICs characteristic of activated and pathological cells. Therapy tailored to reduce these calcified particles should be investigated. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Heart rate variability (HRV in patients with ischemic heart disease, a life-threatening heart rhythm disorders, as well as diabetes mellitus (DM is considered. A significant association between the autonomic regulation of the cardiovascular system and death from cardiovascular causes is identified. The reactions of the autonomic nervous system (ANS can serve as a precipitating factor of arrhythmias in patients with heart disorders. Analysis of HRV at rest is the main and informative method for determination of the ANS disorders. HRV decreases greatly in patients with acute myocardial infarction, cardiac arrhythmia, and DM, predicting a high risk of death. The leading cause of death in diabetic patients is cardiac autonomic neuropathy, with the development of "silent" ischemia and painless myocardial infarction. Autonomic regulation of the heart rate should be assessed for early diagnosis and prevention of complications in the form of sudden death.

    Left ventricular (LV) diastolic functions in 23 patients with aortic regurgitation (AR) and 22 patients with mitral regurgitation (MR) were evaluated by gated blood pool scintigraphy. LV myocardial biopsy was performed during open heart surgery, and LV myocardial ultrastructural changes were evaluated by electron microscope. Correlation between LV diastolic function and myocardial ultrastructural changes was examined. It was suggested that preoperative LV diastolic dysfunction occurred earlier than LV systolic dysfunction in patients with AR and MR. LV early diastolic dysfunction was especially significant in patients with AR. LV systolic function was significantly improved postoperatively compared with LV diastolic function in patients with AR and MR. It was suggested that LV interstitial fibrosis caused LV diastolic dysfunction in patients with AR and MR, and insufficiency of myocardial thickening as compensation in patients with MR. It was presumed that LV diastolic dysfunction was irreversible in patients with AR and MR in the distant postoperative period due to persistence of the preoperative myocardial ultrastructural change, e.g., interstitial fibrosis. These LV diastolic indices measured by gated pool scintigraphy were useful in predicting LV ultrastructural changes and postoperative LV dysfunction in patients with LV volume-overloaded valvular heart disease.

    Although post-traumatic stress disorder (PTSD) is primarily a mental disorder, it can cause additional symptoms that do not seem to be directly related to the central nervous system, which PTSD is assumed to directly affect. PTSD-mediated heart diseases are some of such secondary disorders. In spite of the significant correlations between PTSD and heart diseases, spatial separation between the heart and brain (where PTSD is primarily active) prevents researchers from elucidating the mechanisms that bridge the two disorders. Our purpose was to identify genes linking PTSD and heart diseases. In this study, gene expression profiles of various murine tissues observed under various types of stress or without stress were analyzed in an integrated manner using tensor decomposition (TD). Based upon the obtained features, ∼ 400 genes were identified as candidate genes that may mediate heart diseases associated with PTSD. Various gene enrichment analyses supported biological reliability of the identified genes. Ten genes encoding protein-, DNA-, or mRNA-interacting proteins-ILF2, ILF3, ESR1, ESR2, RAD21, HTT, ATF2, NR3C1, TP53, and TP63-were found to be likely to regulate expression of most of these ∼ 400 genes and therefore are candidate primary genes that cause PTSD-mediated heart diseases. Approximately 400 genes in the heart were also found to be strongly affected by various drugs whose known adverse effects are related to heart diseases and/or fear memory conditioning; these data support the reliability of our findings. TD-based unsupervised feature extraction turned out to be a useful method for gene selection and successfully identified possible genes causing PTSD-mediated heart diseases.

    Myocardial sympathetic nerve function can be evaluated by 123 I-metaiodobenzylguanidine (MIBG) scintigraphy. Congestive heart failure is closely related to myocardial sympathetic nerve function. This study evaluated the severity of congestive heart failure in 30 patients with valvular heart disease [aortic regurgitation (AR): n=20, mean age=70±13 years; mitral regurgitation (MR): n=10, mean age=61±18 years], who had chronic heart failure by MIBG myocardial scintigraphy. Single photon emission computed tomography (SPECT) and anterior planar myocardial images were obtained 15 minutes (initial images) and 4 hours (delayed images) after injection of MIBG (111 MBq). Defect score was determined by the delayed SPECT images visually as a semi-quantitative index. Myocardial MIBG uptake was quantified by the heart to upper mediastinum uptake ratio on the delayed anterior planar images (H/M) and mean cardiac MIBG washout rate during 4 hours was calculated from the bull's eye display data (clearance). These indices were compared with the NYHA class and echocardiographic findings of the patients. MIBG regional defect in the delayed image was most frequently seen in the inferoposterior wall, and defect score and clearance were significantly higher and the H/M ratio was significantly lower in NYHA class III patients than in class II patients. In patients with AR, clearance significantly correlated with left ventricular end-systolic dimension. In patients with MR, both the H/M ratio and clearance significantly correlated with left atrial dimension. Defect score, H/M, and clearance were closely related to the severity of AR and MR. These results indicate that MIBG scan can be used to assess the severity of valvular heart disease. (author)

    2011-01-01

    Purpose: To study incidence of radiation-related heart disease in a large population of breast cancer patients followed for up to 30 years. Material and methods: 72,134 women diagnosed with breast cancer in Denmark or Sweden during 1976-2006 and followed prospectively. Radiation-related risk was studied by comparing women with left-sided and right-sided tumours. Results: 34,825 women (48%) received radiotherapy. Among unirradiated women tumour laterality had little relevance to heart disease. Among irradiated women mean dose to the whole heart was 6.3 Gy for left-sided tumours and 2.7 Gy for right-sided tumours. Mortality was similar in irradiated women with left-sided and right-sided tumours, but incidence ratios, left-sided versus right-sided, were raised: acute myocardial infarction 1.22 (95% CI 1.06-1.42), angina 1.25 (1.05-1.49), pericarditis 1.61 (1.06-2.43), valvular heart disease 1.54 (1.11-2.13). Incidence ratios for all heart disease were as high for women irradiated since 1990 (1.09 [1.00-1.19]) as for women irradiated during 1976-1989 (1.08 [0.99-1.17]), and were higher for women diagnosed with ischaemic heart disease prior to breast cancer than for other women (1.58 [1.19-2.10] versus 1.08 [1.01-1.15], p for difference = 0.01). Conclusions: Breast cancer radiotherapy has, at least until recently, increased the risk of developing ischaemic heart disease, pericarditis and valvular disease. Women with ischaemic heart disease before breast cancer diagnosis may have incurred higher risks than others.

I will focus on the role of fluid dynamics in congenital heart disease and aortic valve calcification. Congenital heart defects are the most common form of birth defect. Aortic valve calcification/stenosis is the third leading cause of adult heart disease and the most common form of acquired valvular disease in developed countries. Given the high incidence of these diseases and their associated morbidity and mortality, the potential translational impact of an improved understanding of cardiac hemodynamic forces is very large.

    Full Text Available Introduction: Rheumatic heart disease still remains one of the leading causes of congestive heart failure and death owing to valvular pathologies, in developing countries. Valve replacement still remains the treatment of choice in such patients.The aim of this study wasto analyze the postoperative outcome of  double valve replacement (Mitral and Aortic in patients of rheumatic heart disease. Materials and Methods: Between 1988 and 2008, 300 patients of rheumatic heart disease underwent double (Mitral and Aortic valve replacement with Starr Edwards valve or St Jude mechanical valve prosthesis were implanted. These patients were studied retrospectively for preoperative data and postoperative outcome including causes of early and late deaths and the data was analyzed statistically. Results: The 30-day hospital death rate was 11.3% andlate death occurred in 11.6%. Anticoagulant regimen was followed to maintain the target pro-thrombin time at 1.5 times the control value. The actuarial survival (exclusive of hospital mortality was 92.4%, 84.6%, and 84.4%, per year at 5, 10, and 20 years, respectively Conclusions: In view of the acknowledged advantageof superior durability, increased thromboresistance in our patient population, and its cost effectiveness the Starr-Edwards ball valve or St. Jude valve is the mechanical prosthesis of choice for advanced combined valvular disease. The low-intensity anticoagulant regimen has offered suffcient protection against thromboembolism as well as hemorrhage.

    Background Valvular heart disease (VHD) is expected to become more common as the population ages. However, current estimates of its natural history and prevalence are based on historical studies with potential sources of bias. We conducted a cross-sectional analysis of the clinical and epidemiological characteristics of VHD identified at recruitment of a large cohort of older people. Methods and results We enrolled 2500 individuals aged ≥65 years from a primary care population and screened for undiagnosed VHD using transthoracic echocardiography. Newly identified (predominantly mild) VHD was detected in 51% of participants. The most common abnormalities were aortic sclerosis (34%), mitral regurgitation (22%), and aortic regurgitation (15%). Aortic stenosis was present in 1.3%. The likelihood of undiagnosed VHD was two-fold higher in the two most deprived socioeconomic quintiles than in the most affluent quintile, and three-fold higher in individuals with atrial fibrillation. Clinically significant (moderate or severe) undiagnosed VHD was identified in 6.4%. In addition, 4.9% of the cohort had pre-existing VHD (a total prevalence of 11.3%). Projecting these findings using population data, we estimate that the prevalence of clinically significant VHD will double before 2050. Conclusions Previously undetected VHD affects 1 in 2 of the elderly population and is more common in lower socioeconomic classes. These unique data demonstrate the contemporary clinical and epidemiological characteristics of VHD in a large population-based cohort of older people and confirm the scale of the emerging epidemic of VHD, with widespread implications for clinicians and healthcare resources.

    This study sought to determine the accuracy of the pre-transplantation clinical diagnosis of heart disease in the United Network for Organ Sharing (UNOS) database. Because survival on the heart transplantation waitlist depends on underlying heart disease, a new allocation system will include the type of heart disease. Accuracy of the pre-transplantation clinical diagnosis and the effect of misclassification are unknown. We included all adults who received transplants at our center between January 2009 to December 2015. We compared the pre-transplantation clinical diagnosis at listing with pathology of the explanted heart and determined the potential effect of misclassification with the proposed allocation system. A total of 334 patients had the following clinical cardiac diagnoses at listing: 148 had dilated cardiomyopathy, 19 had restrictive cardiomyopathy, 103 had ischemic cardiomyopathy, 24 had hypertrophic cardiomyopathy, 11 had valvular disease, 16 had congenital heart disease (CHD), and 13 patients had a diagnosis of "other." Pathology of the explanted hearts revealed 82% concordance and 18% discordance (10% coding errors and 8% incorrect diagnosis). The most common incorrect diagnoses were sarcoidosis (66%), arrhythmogenic right ventricular dysplasia (60%), and other causes of predominately right-sided heart failure (33%). Among the misclassified diagnoses, 40% were listed as UNOS status 2, 8% remained at status 2 at transplantation, and only sarcoidosis and CHD were potentially at a disadvantage with the new allocation. There is high concordance between clinical and pathologic diagnosis, except for sarcoidosis and genetic diseases. Few misclassifications result in disadvantages to patients based on the new allocation system, but rare diseases like sarcoidosis remain problematic. To improve the UNOS database and enhance outcome research, pathology of the explanted hearts should be required post-transplantation. Copyright © 2017 American College of

    Full Text Available Maintenance of sinus rhythm (SR is superior to rate control in atrial fibrillation (AF. In order to achieve SR, we administered single-dose intravenous amiodarone intraoperatively and evaluated its effect on conversion of rheumatic AF to SR in patients undergoing valvular heart surgery. Patients were randomly assigned to amiodarone ( n = 42 or control ( n = 40 group in a double blind manner. The amiodarone group received amiodarone (3 mg/kg intravenously prior to the institution of cardiopulmonary bypass and the control group received the same volume of normal saline. In the amiodarone group, the initial rhythm after the release of aortic cross clamp was noted to be AF in 14.3% ( n = 6 and remained so in 9.5% ( n = 4 of patients till the end of surgery. In the control group, the rhythm soon after the release of aortic cross clamp was AF in 37.5% ( n = 15 ( p = 0.035 and remained so in 32.5% ( n = 13 of patients till the end of surgery ( p = 0.01. At the end of first post-operative day 21.4% ( n = 9 of patients in amiodarone group and 55% ( n = 22 of patients in control group were in AF ( p = 0.002. The requirement of cardioversion/defibrillation was 1.5 (±0.54 in amiodarone group and 2.26 (±0.73 in the control group ( p = 0.014, and the energy needed was 22.5 (±8.86 joules in the amiodarone group and 40.53 (±16.5 in the control group ( p = 0.008. A single intraoperative dose of intravenous amiodarone increased the conversion rate of AF to normal sinus rhythm, reduced the need and energy required for cardioversion/defibrillation and reduced the recurrence of AF within one day.

  3. The pathophysiology of heart failure.

    Heart failure is a clinical syndrome that results when the heart is unable to provide sufficient blood flow to meet metabolic requirements or accommodate systemic venous return. This common condition affects over 5 million people in the United States at a cost of $10-38 billion per year. Heart failure results from injury to the myocardium from a variety of causes including ischemic heart disease, hypertension, and diabetes. Less common etiologies include cardiomyopathies, valvular disease, myocarditis, infections, systemic toxins, and cardiotoxic drugs. As the heart fails, patients develop symptoms which include dyspnea from pulmonary congestion, and peripheral edema and ascites from impaired venous return. Constitutional symptoms such as nausea, lack of appetite, and fatigue are also common. There are several compensatory mechanisms that occur as the failing heart attempts to maintain adequate function. These include increasing cardiac output via the Frank-Starling mechanism, increasing ventricular volume and wall thickness through ventricular remodeling, and maintaining tissue perfusion with augmented mean arterial pressure through activation of neurohormonal systems. Although initially beneficial in the early stages of heart failure, all of these compensatory mechanisms eventually lead to a vicious cycle of worsening heart failure. Treatment strategies have been developed based upon the understanding of these compensatory mechanisms. Medical therapy includes diuresis, suppression of the overactive neurohormonal systems, and augmentation of contractility. Surgical options include ventricular resynchronization therapy, surgical ventricular remodeling, ventricular assist device implantation, and heart transplantation. Despite significant understanding of the underlying pathophysiological mechanisms in heart failure, this disease causes significant morbidity and carries a 50% 5-year mortality.

    1987-01-01

    The list of all potential causes of myocardial disease or injury is an extensive one: a condensed version is presented. Conceptually these processes can be categorized into those which are, or appear to be, primary to the myocardium and those which secondarily involve it. Nuclear imaging procedures, particularly those used to assess ventricular function, are in a general sense potentially applicable to the clinical evaluation of any of these entities. In certain of these conditions, however, nuclear cardiac procedures have a demonstrated or potential additional and more specific role for the diagnosis and quantification of the entity. A number of these, including coronary artery disease, valvular heart disease, cor pulmonale, and myocardial trauma, are the topics of other chapters and, therefore, are not dealt with further here. The remainder of the myocardial disorders in which nuclear imaging procedures have a recognized or potential specific role are the focus of this discussion

    Annuloplasty for functional mitral or tricuspid regurgitation has been made for surgical restoration of valvular diseases. However, these major techniques may sometimes be ineffective because of chamber dilation and valve tethering. We have been developing a sophisticated intelligent artificial papillary muscle (PM) by using an anisotropic shape memory alloy fiber for an alternative surgical reconstruction of the continuity of the mitral structural apparatus and the left ventricular myocardium. This study exhibited the mitral regurgitation with regard to the reduction in the PM tension quantitatively with an originally developed ventricular simulator using isolated goat hearts for the sophisticated artificial PM. Aortic and mitral valves with left ventricular free wall portions of isolated goat hearts (n=9) were secured on the elastic plastic membrane and statically pressurized, which led to valvular leaflet-papillary muscle positional change and central mitral regurgitation. PMs were connected to the load cell, and the relationship between the tension of regurgitation and PM tension were measured. Then we connected the left ventricular specimen model to our hydraulic ventricular simulator and achieved hemodynamic simulation with the controlled tension of PMs.

    Although efficacious in stroke prevention in non-valvular atrial fibrillation, many warfarin patients are sub-optimally managed. To evaluate the association of international normalized ratio control and clinical outcomes among new warfarin patients with non-valvular atrial fibrillation. Adult non-valvular atrial fibrillation patients (≥18 years) initiating warfarin treatment were selected from the US Veterans Health Administration dataset between 10/2007 and 9/2012. Valid international normalized ratio values were examined from the warfarin initiation date through the earlier of the first clinical outcome, end of warfarin exposure or death. Each patient contributed multiple in-range and out-of-range time periods. The relative risk ratios of clinical outcomes associated with international normalized ratio control were estimated. 34,346 patients were included for analysis. During the warfarin exposure period, the incidence of events per 100 person-years was highest when patients had international normalized ratio 3, patients had significantly increased risk of major bleeding (relative risk ratio: 1.5; 95 % confidence interval 1.2-2.0). In a Veterans Health Administration non-valvular atrial fibrillation population, exposure to out-of-range international normalized ratio values was associated with significantly increased risk of adverse clinical outcomes.

    Full Text Available Although antenatal diagnostic technique has considerably improved, precise detection and proper management of the neonate with congenital heart disease (CHD is always a great concern to pediatricians. Congenital cardiac malformations vary from benign to serious conditions such as complete transposition of the great arteries (TGA, critical pulmonary and aortic valvular stenosis/atresia, hypoplastic left heart syndrome (HLHS, obstructed total anomalous pulmonary venous return (TAPVR, which the baby needs immediate diagnosis and management for survival. Unfortunately, these life threatening heart diseases may not have obvious evidence early after birth, most of the clinical and physical findings are nonspecific and vague, which makes the diagnosis difficult. High index of suspicion and astute acumen are essential to decision making. When patent ductus arteriosus (PDA is opened widely, many serious malformations may not be noticed easily in the early life, but would progress as severe acidosis/shock/cyanosis or even death as PDA constricts after few hours to days. Ductus dependent congenital cardiac lesions can be divided into the ductus dependent systemic or pulmonary disease, but physiologically quite different from each other and treatment strategy has to be tailored to the clinical status and cardiac malformations. Inevitably early presentation is often regarded as a medical emergency. Differential diagnosis with inborn error metabolic disorders, neonatal sepsis, persistent pulmonary hypertension of the newborn (PPHN and other pulmonary conditions are necessary. Urgent identification of the newborn at such high risk requires timely referral to a pediatric cardiologist, and timely intervention is the key in reducing mortality and morbidity. This following review deals with the clinical presentations, investigative modalities and approach to management of congenital cardiac malformations presenting in the early life.

    Full Text Available Objective: A study of accessibility of surgical care to elderly patients (aged 60 and above with valvular heart disease has been conducted at the BSCCS "Bakulev Scientific Center of Cardiovascular Surgery» of the Ministry of Health of the Russian Federation. Methods: A retrospective analysis of structure of hospitalizations of 1726 patients, that were hospitalized between 2009 and 2010 at the BSCCS for surgical correction of valvular heart disease was performed. Results: Our study demonstrated that age, on one hand, is not the most significant barrier in the geographical accessibility of cardiac surgical care. On the other hand, it can influence the availability in general, taking into account other factors (urban / rural areas, the presence of cardiac surgical clinics, and clinical status. Provision of cardiac surgical care for patients with heart defects at the BSCCS per 1 million population varies considerably in the context of federal districts and is 0.4 for the Siberian Federal District 30 for the Central Federal District (the highest is 42 for the Moscow Region. Conclusion: Thus, our study demonstrated accessibility of surgical care for elderly patients is the highest for the urban areas with specialized cardiac surgery centers, where patients referred from rural regions

    Multiple and yet uncertain connections exist between cardiovascular diseases and the nutritional status of patients, particularly in relation to cardiovascular treatments. Proton pump inhibitors (PPI) are among the most commonly used group of drugs. To analyse utilisation of PPI in association with nutritional risk of patients scheduled for rehabilitation after treatment for ischaemic and valvular heart disease. Retrospective analyses on a consecutive sample of patients, which included drug utilisation of PPI and nutritional risk screening, using a standardised NRS-2002 tool. The patients (n = 536) were divided into groups based on previous cardiovascular treatments and use of PPI. Nearly half of the patients (244, 46.1%) had PPI in their chronic therapy despite the clinically negligible prevalence of conditions that are their fundamental indications. The odds for using PPI in patients with increased nutritional risk, estimated by logistic regression, were 3.34 (95% confidence intervals [CI] 2.26-4.94), p 3: positive likelihood-ratio (LR) 2.35 (95% CI 2.10-2.60); negative LR 0.46 (95% CI 0.4-0.6); area under the curve (AUC) 0.720; p 6.36% (positive LR 2.22 [95% CI 2.00-2.50]; negative LR 0.41 [95% CI 0.30-0.50]; AUC 0.707; p < 0.001). Utilisation of PPI was found to be of relatively high prevalence and significantly associated with parameters of nutritional risk screening. Furthermore, it was in correlation with the age of patients and the existence of chronic kidney disease, which are well-established predispositions for poor nutritional status. Nutritional risk seems to be additionally negatively challenged by utilisation of PPI due to gastric malabsorption and anaemia.

    Induced pluripotent stem cells (iPSCs) offer an unprece-dented opportunity to study human physiology and disease at the cellular level. They also have the potential to be leveraged in the practice of precision medicine, for example, personalized drug testing. This statement comprehensively describes the provenance of iPSC lines, their use for cardiovascular disease modeling, their use for precision medicine, and strategies through which to promote their wider use for biomedical applications. Human iPSCs exhibit properties that render them uniquely qualified as model systems for studying human diseases: they are of human origin, which means they carry human genomes; they are pluripotent, which means that in principle, they can be differentiated into any of the human body's somatic cell types; and they are stem cells, which means they can be expanded from a single cell into millions or even billions of cell progeny. iPSCs offer the opportunity to study cells that are genetically matched to individual patients, and genome-editing tools allow introduction or correction of genetic variants. Initial progress has been made in using iPSCs to better understand cardiomyopathies, rhythm disorders, valvular and vascular disorders, and metabolic risk factors for ischemic heart disease. This promising work is still in its infancy. Similarly, iPSCs are only just starting to be used to identify the optimal medications to be used in patients from whom the cells were derived. This statement is intended to (1) summarize the state of the science with respect to the use of iPSCs for modeling of cardiovascular traits and disorders and for therapeutic screening; (2) identify opportunities and challenges in the use of iPSCs for disease modeling and precision medicine; and (3) outline strategies that will facilitate the use of iPSCs for biomedical applications. This statement is not intended to address the use of stem cells as regenerative therapy, such as transplantation into the body to

El seguimiento de estos pacientes puede ser complejo; los síntomas iniciales de disfunción valvular protésica son inespecíficos y en ocasiones es difícil diferenciar entre los efectos de la disfunción valvular, las patologías no cardíacas, la disfunción ventricular y la hipertensión pulmonar. Aunque el examen físico puede alertar al clínico acerca de alteraciones, se requieren otros métodos diagnósticos para evaluar la función de la prótesis. La ecocardiografía Doppler es el método de elección no invasivo para estudiar la función valvular y pese a que muchas de las mediciones y parámetros de normalidad y anormalidad son extrapolados de estudios en adultos, se han tratado de definir estándares en pacientes pediátricos.

    Current treatment strategy for end stage valve disease involves either valvular repair or replacement with homograft/mechanical/bioprosthetic valves. In cases of recurrent stenosis/ regurgitation, valve replacement is preferred choice of treatment over valvular repair. Currently available mechanical valves primarily provide durability whereas bioprosthetic valves have superior tissue compatibility but both lack remodelling and regenerative properties making their utility limited in paediatric patients. With advances in tissue engineering, attempts have been made to fabricate valves with regenerative potential using various polymers, decellularized tissues and hybrid scaffolds. To engineer an ideal heart valve, decellularized bovine pericardium extracellular matrix (DBPECM) is an attractive biocompatible scaffold but has weak mechanical properties and rapid degradation. However, DBPECM can be modified with synthetic polymers to enhance its mechanical properties. In this study, we developed a Bio-Hybrid scaffold with non-cross linked DBPECM in its native structure coated with a layer of Polycaprolactone-Chitosan (PCL-CH) nanofibers that displayed superior mechanical properties. Surface and functional studies demonstrated integration of PCL-CH to the DBPECM with enhanced bio and hemocompatibility. This engineered Bio-Hybrid scaffold exhibited most of the physical, biochemical and functional properties of the native valve that makes it an ideal scaffold for fabrication of cardiac valve with regenerative potential. - Highlights: • A Bio-Hybrid scaffold was fabricated with PCL-CH blend and DBPECM. • PCL-CH functionally interacted with decellularized matrix without cross linking. • Modified scaffold exhibited mechanical properties similar to native heart valve. • Supported better fibroblast and endothelial cell adhesion and proliferation. • The developed scaffold can be utilized for tissue engineering of heart valve.

    Artifical valve prostheses are often regarded as a contraindication for magnetic resonance imaging (MRI), although preliminary in vitro studies suggested, that patients with these metallic implants might safely undergo MR examination. This study reports on the experience with a group of 89 patients with 100 heart valve prostheses who were examined by spin-echo MR and gradient-echo MR. MR examination was performed in all patients without complications. The spin-echo sequence showed advantages in the depiction of anatomical structures like paravalvular abcesses. Anatomical structures adjacent to the artificial valve were clearly visivle and the metal components of the valves showes no or only small artifacts. Artifacts were accentuated when using gradient-echo sequences. Gradient-echo sequences provided valuable information regarding the presence of valvular insufficiency. Physiological valvular regurgitation was easy to differentiate from pathological paravalvular or transvalvular regurgitation. These results demonstrate that patients with artificial valve prostheses can be imaged by MR without risk and that prosthesis-induced artifacts do no interfere with image interpretation. (orig.) [de

    Undiagnosed and untreated sleep-disordered breathing can lead to negative health outcomes and increased utilization of health resources among patients with heart failure. The purpose of this evidence-based practice project was to implement and evaluate a new multifaceted sleep-disordered breathing screening protocol in a heart failure disease management clinic. The combined use of a symptoms questionnaire, the Epworth sleepiness scale, and overnight pulse oximetry was significantly more effective in identifying patients with a positive diagnosis of sleep-disordered breathing than using the Epworth sleepiness scale alone (P < .05).

    In this report we attempt to demonstrate the efforts involved in establishing and organizing the heart transplant program at the Armed Forces Hospital in Riyadh, Saudi Arabia. From 1986 to date, 25 orthotopic heart transplants were performed at this center. Patient age ranged from 22 months to 57 years; 4 patients were below 12 years of age and 4 aged 50 years and above. The incidations for transplantation were cardiomyopathy in 15 patients, ischemic heart disease in 6 patients, and valvular heart disease in 4 patients. Fourteen recipients have died. Three of them were classified as hospital deaths, occuring before the patient could be discharged after the procedure; the reminder died from rejection and associated problems. Eight patients of them died within the first year. The longest survival period was almost 8 years. The overall 8 years survival rate was 45%, which is comparable to the international figures. Shortage of donors may affect the future of the transplant programs. Increasing the awareness of the public about the importance of organ donation and transplantation is crucial in this regard.

    Objective: To examine the prevalence, age, sex and topographical distribution of the rheumatic heart diseases and its morphology. Design: A cross sectional descriptive study. Place and Duration of Study: Pathology Department, Army Medical College, Rawalpindi between 1981-1990. Patients and Methods: Five hundred and twenty six surgically excised cardiac valves and biopsies were studied in the laboratory in the light of clinical data. Results: Carditis constituted 87.4 % of the cardiac valvular disease with 23.5% active and 71% healed rheumatic lesions. About 5.5% had morphological appearances consistent with RHD. The lesions affected mitral valves (37.0%), aortic valve (22.1%), mitral and aortic valves together (21.0%) and atrial appendages (19.0%). Presentation was mostly as mitral stenosis either isolated (49.2% ) or combined (31.0%), aortic stenosis (11.7% ) and aortic incompetence with regurgitation (7.3%). Conclusion: Rheumatic carditis constitutes a significant proportion of cardiac valvular disease and affects comparatively younger age, with slight male preponderance and primarily affects mitral valve.

    The aim of this study was to test the primary hypothesis of altered Heart Rate Variability (HRV) and heart rate in a sample of patients with mental disorders and the secondary hypothesis of normalization of HRV values as a result of clinical improvement. The study was conducted on a sample of 90 patients with psychotic, anxiety and mood disorders. Each patient was subjected to detection of HRV and heart rate via a photoplethysmographic sensor and evaluated with rating scales based on the specific disorder. The parameters detected in the sample were compared with a control group of healthy subjects. There were no significant differences of cardiac autonomic modulation between the group of patients in whom is possible exclude the drug influence and the control group; significantly lower values of HRV parameters in the group of patients with drug influence, and especially in subgroup of psychotic patients, compared to controls, are, instead, detected. The study also shows a significant increase in heart rate as a common feature in mental disorders, regardless of treatment. Clinical improvement appears to promote the normalization of the variability in patients with high DS of tachogram. The study suggests a potential increased risk of cardiovascular mortality in patients, as evidenced by the increased values of heart rate, regardless of drug treatment. This risk is even more pronounced in psychotic patients in drug treatment because of the simultaneous significant reduction of HRV parameters.

    Introduction Atrial fibrillation (AF), the most common cardiac arrhythmia, affects approximately 2.3 million patients in the United States, costing around $26 billion. Atrial fibrillation is associated with a two- to seven-fold increased risk of stroke, one of the most serious complications. Chronic kidney disease affects approximately 13% of the US population and has been associated with higher rates of AF than the general population. In patients with chronic kidney disease (CKD), the risk of stroke increases as the glomerular filtration rate (GFR) decreases, especially in CKD stages three and four. Several risks stratification scores such as CHADS2 (congestive heart failure, hypertension, age, diabetes mellitus, stroke), CHA2DS2VASc (congestive heart failure, hypertension, age, diabetes mellitus, stroke, vascular disease, age, sex), and R2CHADS2 (renal failure, congestive heart failure, age, diabetes, stroke) scores are used for stroke risk assessment in patients with non-valvular atrial fibrillation (NVAF). This study investigates the association between renal functions and risk stratification scoring systems in patients with non-valvular AF presenting with stroke. Methods Using the convenience sampling method, 171 subjects were selected from the eligible population (n = 386). A Pearson product-moment correlation coefficient was calculated to determine the association between the GFR and each of the CHA2DS2VASc and R2CHADS2 scores. In addition, a Pearson product-moment correlation coefficient was calculated to determine the association between the CHA2DS2VASc and R2CHADS2 scores. Results The selected population represented 44.3% of the eligible subjects. Of these, 88% were Caucasian, 60% were female, and the mean age was 78 years. The mean CHA2DS2VASc score was six (range 2-9). The mean eGFR was 69.77 (range 6-108). Both the mode and the median CHA2DS2VASc score was four (range 2-8). A weak, but significant, negative correlation was found between renal

    Background: Left ventricular (LV) function is a vital parameter for prognosis, therapy guidance, and follow-up of cardiovascular disease. Dual-source computed tomography (DSCT) provides an accurate analysis of global LV function. Purpose: To assess the performance of DSCT in the determination of global LV functional parameters in comparison with cardiovascular magnetic resonance (CMR) and two-dimensional transthoracic echocardiography (2D-TTE) in patients with valvular heart disease (VHD). Material and Methods: A total of 111 patients (58 men, mean age 49.9 years) with known VHD and who underwent DSCT, 2D-TTE, and CMR a period of 2 weeks before undergoing valve surgery were included in this study. LV end-systolic volume (ESV), end-diastolic volume (EDV), stroke volume (SV), and ejection fraction (EF) were calculated by DSCT using the threshold-based technique, by 2D-TTE using a modified Simpson's method, and by CMR using Simpson's method. Agreement for parameters of LV global function was determined with the Pearson's correlation coefficient (r) and Bland-Altman analysis. All the DSCT and CMR data-sets were assessed independently by two readers. Results: Fifty of the total 111 patients had aortic VHD, 29 patients had mitral VHD, and 32 patients had mixed aortic and mitral VHD. An excellent inter-observer agreement was seen for the assessment of global LV function using DSCT (r 0.910-0.983) and CMR (r = 0.854-0.965). An excellent or good correlation (r 0.93, 0.95, 0.87, and 0.71, respectively, P < 0.001) was noted between the DSCT and 2D-TTE values for EDV, ESV, SV, and EF. EDV (33.7 mL, P < 0.001), ESV (12.1 mL, P < 0.001), SV (21.2 mL, P < 0.001), and EF (1.6%, P = 0.019) were significantly overestimated by DSCT when compared with 2D-TTE. An excellent correlation (r = 0.96, 0.97, 0.91, and 0.94, respectively, P < 0.001) between DSCT and CMR was seen in the evaluation of EDV, ESV, SV, and EF. EDV (15.9 mL, P < 0.001), ESV (7.3 mL, P < 0.001), and SV (8.5 mL, P < 0

    Calcific aortic valve disease (CAVD) is a major cardiovascular disorder caused by osteogenic differentiation of valvular interstitial cells (VICs) within aortic valves. Conventional methods like colorimetric assays and histology fail to detect small calcium depositions during in-vitro VIC cultures. Laser-induced breakdown spectroscopy (LIBS) is a robust analytical tool used for inorganic materials characterizations, but relatively new to biomedical applications. We employ LIBS, for the first time, for quantitative in-vitro detection of calcium depositions in VICs at various osteogenic differentiation stages. VICs isolated from porcine aortic valves were cultured in osteogenic media over various days. Colorimetric calcium assays based on arsenazo dye and Von Kossa staining measured the calcium depositions within VICs. Simultaneously, LIBS signatures for Ca I (422.67 nm) atomic emission lines were collected for estimating calcium depositions in lyophilized VIC samples. Our results indicate excellent linear correlation between the calcium assay and our LIBS measurements. Furthermore, unlike the assay results, the LIBS results could resolve calcium signals from cell samples with as early as 2 days of osteogenic culture. Quantitatively, the LIBS measurements establish the limit of detection for calcium content in VICs to be ∼0.17±0.04 μg which indicates a 5-fold improvement over calcium assay.

    The objective of our study was to compare the cellular and extracellular matrix (ECM) structure and the biomechanical properties of human pericardium (HP) with the normal human aortic heart valve (NAV). HP tissues (from 12 patients) and NAV samples (from 5 patients) were harvested during heart surgery. The main cells in HP were pericardial interstitial cells, which are fibroblast-like cells of mesenchymal origin similar to the valvular interstitial cells in NAV tissue. The ECM of HP had a statistically significantly (p structures of the two tissues, the dense part of fibrous HP (49 ± 2%) and the lamina fibrosa of NAV (47 ± 4%), was similar. In both tissues, the secant elastic modulus (Es) was significantly lower in the transversal direction (p structure and has the biomechanical properties required for a tissue from which an autologous heart valve replacement may be constructed.

    Full Text Available Background: Anxiety disorders increase risk of future cardiovascular disease (CVD and mortality, even after controlling for confounds including smoking, lifestyle, and socioeconomic status, and irrespective of a history of medical disorders. While impaired vagal function, indicated by reductions in heart rate variability (HRV, may be one mechanism linking anxiety disorders to CVD, prior studies have reported inconsistent findings highlighting the need for meta-analysis.Method: Studies comparing resting state HRV recordings in patients with an anxiety disorder as a primary diagnosis and healthy controls were considered for meta-analysis. Results: Meta-analyses were based on 36 articles, including 2086 patients with an anxiety disorder and 2294 controls. Overall, anxiety disorders were characterised by lower HRV (high frequency: Hedges’ g = -.29. 95%CI: -.41 to -.17, p < 0.001; time domain: Hedges’ g = -0.45, 95%CI: -0.57 to -0.33, p < .001 than controls. Panic Disorder (n=447, Post-Traumatic Stress Disorder (n=192, Generalized Anxiety Disorder (n=68, and Social anxiety disorder (n=90, but not Obsessive Compulsive Disorder (n=40, displayed reductions in high frequency HRV relative to controls (all ps < .001. Conclusions: Anxiety disorders are associated with reduced HRV, findings associated with a small to moderate effect size. Findings have important implications for future physical health and wellbeing of patients, highlighting a need for comprehensive cardiovascular risk reduction.

    Endocrine disorders are associated with various tachyarrhythmias, including atrial fibrillation (AF), ventricular tachycardia (VT), ventricular fibrillation (VF), and bradyarrhythmias. Along with underlying arrhythmia substrate, electrolyte disturbances, glucose, and hormone levels, accompanying endocrine disorders contribute to development of arrhythmia. Arrhythmias may be life-threatening, facilitate cardiogenic shock development and increase mortality. The knowledge on the incidence of tachy- and bradyarrhythmias, clinical and prognostic significance as well as their management is limited; it is represented in observational studies and mostly in case reports on management of challenging cases. It should be also emphasized, that the topic is not covered in detail in current guidelines. Therefore, cardiologists and multidisciplinary teams participating in care of such patients do need the evidence-based, or in case of limited evidence expert-opinion based recommendations, how to treat arrhythmias using contemporary approaches, prevent their complications and recurrence in patients with endocrine disorders. In recognizing this close relationship between endocrine disorders and arrhythmias, the European Heart Rhythm Association (EHRA) convened a Task Force, with representation from Asia-Pacific Heart Rhythm Society (APHRS) and Sociedad Latinoamericana de Estimulación Cardíaca y Electrofisiología (SOLAECE), with the remit of comprehensively reviewing the available evidence and publishing a joint consensus document on endocrine disorders and cardiac arrhythmias, and providing up-to-date consensus recommendations for use in clinical practice.

    The study covers 300 clinically healthy, randomly selected young subjects, aged 17 to 21 years. The incidence and characteristic features of the valvular regurgitations are assayed by means of pulsed and continuous transthoracic Doppler echocardiography. Valvular insufficiency is registered in total of 198 cases (66%). Regurgitation of single valve is observed in 122 cases (61%), regurgitation of two valves - in 70 (36%) and three valves - in six (3%). Right-sided regurgitations (tricuspid, pulmonic and a combination of both) are detected in 156 subjects, and left-sided (mitral and/or aortic) in twenty-six of which only one regurgitation of the aortic valve. There is a definite tendency of the first two to prevail at a ratio 6:1. A constellation of various anatomical and physiological factors are considered as a likely underlying cause. Whenever atrio-ventricular valves are examined (the mitral one in particular), it is necessary that the regurgitation jet involves over 50% of systole in order to avoid hyperdiagnostics and the so-called 'Doppler's disease'. 14 refs., 1 tab., 2 figs.

    Full Text Available Introduction: In 80% of patients with anorexia nervosa (AN cardiological complications occur. Changes in electrocardio‑ gram (ECG are found in over 80% of AN patients. Dangerous cardiological complications among AN patients include also congestive heart failure, presence of pericardial effusion, decreased volume of left ventricle mass, disturbed mobility of the cusps of mitral and tricuspid valve at the correct structure of valvular and subvalvular system. Aim: The aim of the study was assessment of the incidence and severity of cardiological disorders found in electrocardiographic test and echocardiography in patients with AN, depending on the form of the disease. Material and methods: The study involved 34 patients with diag‑ nosed AN according to DSM‑IV criteria: 17 patients were diagnosed with restricting type of AN, the other 17 – binge/purg‑ ing type of AN. Each patient underwent electrocardiographic and ultrasonographic examinations of the heart. Results: Changes in electrocardiograms were found in 79% of patients with AN (similar incidence in binge/purging and restricting type. Disorders in depolarization and repolarization of ventricular muscle were noted in 47% of patients (18% of patients with binge/purging type and 47% of patients with restricting type, p<0.05. A significant difference was indicated in the left ventricle mass index (LVMI between patients with binge/purging type and patients with restricting type (23.9±5.28 vs 21.2±3.81, p<0.05. In 67% of patients with restricting type of AN, as compared to 33% with binge/purging type (p<0.05, mild, haemodynamically insignificant heart diseases were found. Only in one patient the mobility disorders were found: tri‑ cuspid valve cusp prolapse which was concomitant with the 2nd degree valvular insufficiency. Conclusions: Restricting type, as compared to binge/purging type, is characterized by an increased percentage of disorders of depolarization and repolar‑ ization

Las complicaciones por el procedimiento son bien conocidas pero el daño valvular mitral es infrecuente. Se presenta un paciente masculino, de siete meses de edad, con el diagnóstico de coartación de la aorta y estenosis valvular aórtica a quién se le realizó dilatación de ambas lesiones por cateterismo intervencionista. A las 20 horas del procedimiento se diagnosticó insuficiencia cardíaca grave secundaria a lesión de la valva anterior mitral. Se intervino quirúrgicamente de urgencia y se observó un desgarro en forma de hendidura desde el borde libre hasta el anillo, el cual se reparó y se realizó anuloplastia en la comisura lateral. En el postoperatorio inmediato evolucionó sin complicaciones y al año de seguimiento presenta insuficiencia valvular mitral leve sin signos de recoartación ni de estenosis valvular aórticas. / Abstract: Balloon valvuloplasty is widely accepted as the treatment of choice for congenital aortic stenosis in newborns and infants. Complications from the procedure are well known but mitral valve damage is rare. This is the case of a 7-month-old male patient with the diagnosis of coarctation of the aorta and aortic valve stenosis who underwent dilation of both lesions via catheterization. At 20 hours of the procedure a severe heart failure secondary to an injury of the anterior mitral valve was diagnosed. The patient underwent emergency surgery and a slit-like tear from the free edge to the annulus was observed, which was repaired and annuloplasty in the lateral commissure was performed. In the immediate postoperative period the patient progressed without complications and at one year follow up he shows mild valve regurgitation without evidence of recoarctation or aortic valve stenosis.

    Full Text Available Abstract Background Carcinoid heart disease, a known complication of neuroendocrine tumors, is characterized by right heart fibrotic lesions. Carcinoid heart disease has traditionally been defined by the degree of valvular involvement. Right ventricular (RV dysfunction due to mural involvement may also be a manifestation. Connective tissue growth factor (CCN2 is elevated in many fibrotic disorders. Its role in carcinoid heart disease is unknown. We sought to investigate the relationship between plasma CCN2 and valvular and mural involvement in carcinoid heart disease. Methods Echocardiography was performed in 69 patients with neuroendocrine tumors. RV function was assessed using tissue Doppler analysis of myocardial systolic strain. Plasma CCN2 was analyzed using an enzyme-linked immunosorbent assay. Mann-Whitney U, Kruskal-Wallis, Chi-squared and Fisher's exact tests were used to compare groups where appropriate. Linear regression was used to evaluate correlation. Results Mean strain was -21% ± 5. Thirty-three patients had reduced RV function (strain > -20%, mean -16% ± 3. Of these, 8 had no or minimal tricuspid and/or pulmonary regurgitation (TR/PR. Thirty-six patients had normal or mildly reduced RV function (strain ≤ -20%, mean -25% ± 3. There was a significant inverse correlation between RV function and plasma CCN2 levels (r = 0.47, p Conclusions Elevated plasma CCN2 levels are associated with RV dysfunction and valvular regurgitation in NET patients. CCN2 may play a role in neuroendocrine tumor-related cardiac fibrosis and may serve as a marker of its earliest stages.

    Improvements in the outcomes of surgical and catheter-based interventions and medical therapy have led to a growing population of adult patients with congenital heart disease. Adult patients with previously undiagnosed congenital heart disease or those previously palliated or repaired may have challenging echocardiographic examinations. Understanding the distinct anatomic and hemodynamic features of the congenital anomaly and quantifying ventricular function and valvular dysfunction plays an important role in the management of these patients. Rapid advances in imaging technology with magnetic resonance imaging (MRI) and computed tomography angiography (CTA) allow for improved visualization of complex cardiac anatomy in the evaluation of this unique patient population. Although echocardiography remains the most widely used imaging tool to evaluate congenital heart disease, alternative and, at times, complimentary imaging modalities should be considered. When caring for adults with congenital heart disease, it is important to choose the proper imaging study that can answer the clinical question with the highest quality images, lowest risk to the patient, and in a cost-efficient manner.

    Full Text Available Patients with replaced heart valve submitted to echocardiographic examination may have symptoms related either to valvular malfunction or ventricular dysfunction from different causes. Clinical examination is not reliable in a prosthetic valve evaluation and the main information regarding its function could be obtained using different cardiac ultrasound modalities. This review provides a description of echocardiographic and Doppler techniques useful in evaluation of prosthetic heart valves. For the interpretation of echocardiography there is a need in special knowledge of prosthesis types and possible reasons of prosthetic function deterioration. Echocardiography allows to reveal valve thrombosis, pannus formation, vegetation and such complications of infective endocarditis as valve ring abscess or dehiscence. Transthoracic echocardiography requires different section plane angles and unconventional views. Transesophageal echocardiography is more often used than in native valve examination due to better visualization of prosthetic valve structure and function. Three-dimensional echocardiography could provide more detailed visual information especially in the assessment of paravalvular regurgitation or valve obstruction.

    In Streptococcus sanguinis (sanguis) induced experimental endocarditis, we sought evidence that the development of aortic valvular vegetation depends on the availability of fibrin. Endocarditis was induced in New Zealand white rabbits by catheter placement into the left ventricle and inoculation of the bacteria. Fibrin was localized in the developing vegetation with 99mTechnetium (Tc)-labeled anti-fibrin antibody one or three days later. When rabbit anti-fibrin antibody was given intravenously on day 1, the mass of aortic valvular vegetation was significantly reduced at day 3; infusion of non-specific rabbit IgG showed no effect. The 99mTc-labeled anti-fibrin antibody also labeled kidneys that showed macroscopic subcapsular hemorrhage. To learn if the deposition of fibrin in the kidneys was a consequence of endocarditis required a comparison of farm-bred and specific pathogen-free rabbits before and after the induction of endocarditis. Before induction, the kidneys of farm-bred rabbits were labeled, but specific pathogen-free rabbits were free of labeling and signs of macroscopic hemorrhage. After 3 days of endocarditis, kidneys of 10 of 14 specific pathogen-free rabbits labeled with 99mTc-labeled anti-fibrin antibody and showed hemorrhage. Kidney lesions were suggested to be a frequent sequellae of S. sanguinis infective endocarditis. For the first time, fibrin was shown to be required for the continued development of aortic valvular vegetations.

    The FMCG in 22 patients with valvular prosthesis is analyzed and its clinical, hemodynamic and surgical correlation are established (11 from the I.N.C. and 11 from the Hospital Infantil I.M.A.N.). The average age of the patients was 15 years old, 18 had a mitral and six aortic valvulopathy, and they all required a valvular replacement. Of the mitral prosthesis, 14 were Starr-Edwards (13 of ball valve and one of disc), three Lillehei-Kaster and one Börck-Shiley. In 5 patients, the FMCG suspected disfunction that was later corroborated by catheterism in three patients and by surgery in all of them. The important differences of the FMCG between the group with good and the one with bad function were: the aparition of a rumble, a decrease in the amplitud of the closing snap, index of closing snap opering snap of less than one, lenghtening of fases PFVP and IVCP, and shortening of IVDRP. In the patients with auricular fibrilation, after long dyastoles; that would represent an adequate atrial emptying; the closing snap was more intense, the PFVP was lennthened the IVDRP was shortened when the prosthesis was not properly functioning. All the aortic prosthesis were ball valve Starr-Edwards type; in one the FMCG suspected disfunction and the patient had a sudden death outside of the Hospital. The significant differences of the FMCG were the decrease in the intensity of the opening snap, with a Hylen index of less than one, lengthening of the PFVP, IVCP and of the expulsive period (EP). The authors conclude that the FMCG is a good method for an early detection of the disfunctions of valvular prosthesis.

    Full Text Available Aim: Degenerative valvular heart disease (DVHD may cause serious cardiac problems and mortality. Determination of the factors related to DVHD may render possible the prevention and/or slowing down the progression of DVHD. In this study, we evaluated the relationship of DVHD with lipid profile, microalbuminuria and high sensitive C-reactive protein (hsCRP levels. Methods: 50 patients (age=65.6±12.4 years with DVHD were compared with the control group including 20 patients (age=57.3±13.9 years with left ventricle hypertrophy, but no DVHD. Microalbuminuria, blood lipid parameters and hsCRP levels were measured besides routine biochemical tests. Clinical, laboratory and echocardiographic findings were compared between the groups. Results: Total cholesterol, HDL-cholesterol and LDL-cholesterol levels were significantly higher in DVHD group (215.26±48.59 mg/dL vs. 177.45±22.47 mg/dL, p=0.001; 45.04±11.03 mg/dL vs. 38.90±11.82 mg/dL, p=0.043 and 138.49±40.69 mg/dL vs. 114.26±16.07 mg/dL, p=0.001 compared with control group. hsCRP and microalbuminuria levels were relatively higher in DVHD group. Conclusion: Hyperlipidaemia is related to DHVD development, and the progress of DHVD may be related to the inflammatory process. Elevated hsCRP levels may be an indicator of pathologies active in DVHD development. Routine echocardiographic analysis in hypertensive patients with high hsCRP and LDL-cholesterol levels might be useful for screening of DVHD. (The Medical Bulletin of Haseki 2015; 53: 62-6

    We experienced the rare case of an elderly woman with uncorrected tetralogy of Fallot. She also had significant mitral and tricuspid regurgitation with deteriorated ventricular function and ischemic coronary artery disease. We performed a radical repair of the tetralogy of Fallot, valvular operations for the mitral and tricuspid regurgitation, and coronary artery bypass grafting. Although mechanical circulatory support was required postoperatively, she recovered well to New York Heart Association functional class II. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Despite the paucity of data available, orally administered angiotensin-converting enzyme (ACE) inhibitors are empirically used in horses with valvular regurgitation. Evaluate the echocardiographic and hormonal changes in response to oral benazepril in horses with left-sided valvular regurgitation. Prospective, randomised double-blind, placebo-controlled trial. Horses with mitral valve (MR) and/or aortic valve regurgitation (AR) received oral benazepril (n = 6) at a dosage of 1 mg/kg q 12 h or a placebo (n = 5) for 28 days. Echocardiography was performed before drug administration and after 28 days of treatment. Plasma renin activity, serum ACE activity, angiotensin II concentration, aldosterone concentration and biochemical variables were measured before drug administration and after 7 and 28 days of treatment. Relative to baseline, horses treated with benazepril had statistically significant reduction in left ventricular internal diameter in systole (mean difference between groups = -0.97 cm; 95% CI = -1.5 to -0.43 cm), aortic sinus diameter (-0.31 cm; -0.54 to -0.07 cm), and percentage of the aortic annulus diameter occupied by the base of the AR jet (-17.05%; -31.17 to -2.93%) compared with horses receiving a placebo. In addition, horses treated with benazepril had a significantly greater increase in cardiac output (11.95 L/min; 1.17-22.73 L/min) and fractional shortening (7.59%; 3.3-11.88%) compared with horses receiving a placebo. Despite profound serum ACE inhibition, renin activity and concentrations of angiotensin II and aldosterone were not significantly different between treatment groups or among time points. Very small sample size and short treatment period. Treatment with oral benazepril resulted in statistically significant echocardiographic changes that might indicate reduced cardiac afterload in horses with left-sided valvular regurgitation. Additional studies with a larger sample size will be necessary to determine if administration of benazepril is

  8. Gamma radiation and its role in bio prosthetic aortic valves implanted in rat hearts

    Porcine heart valves glutaraldehyde fixed are implanted in patients with valvular deterioration. Mineralization may be the major factor in the long-term failure of tissue bio prosthesis. Gamma radiation randomly breaks some glutaraldehyde cross-links. As a consequence of irradiation, the polymeric fibers belonging to the valvular tissue are broken too, leading to sites of collagen fiber disorganisation. It is well known that the collagen fibers may act as a passive nucleator of salts where the calcium phosphate salts precipitate. This salt concentration has been described in association with disintegrated sites of protein fiber, which may favour new sites where the calcium salts would be deposit. The irradiation process is a technique used for sterilization of porcine heart valve. The main objective of this work was to study the effect of different doses of gamma radiation on the calcification process of subcutaneously implanted valves in rats. Small pieces from glutaraldehyde fixed valves, irradiated to different doses with a 60 Co sources were implanted subcutaneously in rats. The calcium was measured by X-ray and atomic absorption spectrophotometry. In our experimental conditions and at the radiation doses used in these tests, the calcium measurements on control and irradiated material were not significantly different. We conclude that, at the employed doses, the gamma radiation does not alter the process. (author) [es

    Background Hypoplastic right heart syndrome (HRHS) is a rare congenital defect characterized by underdevelopment of the right heart structures commonly accompanied by an atrial septal defect. Familial HRHS reports suggest genetic factor involvement. We examined the role of copy number variants (CNVs) in HRHS. Methods We genotyped 32 HRHS cases identified from all New York State live births (1998–2005) using Illumina HumanOmni2.5 microarrays. CNVs were called with PennCNV and prioritized if they were ≥20Kb, contained ≥10 SNPs and had minimal overlap with CNVs from in-house controls, the Database of Genomic Variants, HapMap3 and CHOP database. Results We identified 28 CNVs in 17 cases; several encompassed genes important for right heart development. One case had a 2p16–2p23 duplication spanning LBH, a limb and heart development transcription factor. Lbh mis-expression results in right ventricular hypoplasia and pulmonary valve defects. This duplication also encompassed SOS1, a factor associated with pulmonary valve stenosis in Noonan syndrome. Sos1−/− mice display thin and poorly trabeculated ventricles. In another case, we identified a 1.5Mb deletion associated with Williams Beuren syndrome, a disorder that includes valvular malformations. A third case had a 24Kb deletion upstream of the TGFβ ligand ITGB8. Embryos genetically null for Itgb8, and its intracellular interactant Band 4.1B, display lethal cardiac phenotypes. Conclusions To our knowledge, this is the first study of CNVs in HRHS. We identified several rare CNVs that overlap genes related to right ventricular wall and valve development, suggesting that genetics plays a role in HRHS and providing clues for further investigation.

    Background: Left ventricular (LV) function is a vital parameter for prognosis, therapy guidance, and follow-up of cardiovascular disease. Dual-source computed tomography (DSCT) provides an accurate analysis of global LV function. Purpose: To assess the performance of DSCT in the determination of global LV functional parameters in comparison with cardiovascular magnetic resonance (CMR) and two-dimensional transthoracic echocardiography (2D-TTE) in patients with valvular heart disease (VHD). Material and Methods: A total of 111 patients (58 men, mean age 49.9 years) with known VHD and who underwent DSCT, 2D-TTE, and CMR a period of 2 weeks before undergoing valve surgery were included in this study. LV end-systolic volume (ESV), end-diastolic volume (EDV), stroke volume (SV), and ejection fraction (EF) were calculated by DSCT using the threshold-based technique, by 2D-TTE using a modified Simpson's method, and by CMR using Simpson's method. Agreement for parameters of LV global function was determined with the Pearson's correlation coefficient (r) and Bland-Altman analysis. All the DSCT and CMR data-sets were assessed independently by two readers. Results: Fifty of the total 111 patients had aortic VHD, 29 patients had mitral VHD, and 32 patients had mixed aortic and mitral VHD. An excellent inter-observer agreement was seen for the assessment of global LV function using DSCT (r 0.910-0.983) and CMR (r = 0.854-0.965). An excellent or good correlation (r 0.93, 0.95, 0.87, and 0.71, respectively, P < 0.001) was noted between the DSCT and 2D-TTE values for EDV, ESV, SV, and EF. EDV (33.7 mL, P < 0.001), ESV (12.1 mL, P < 0.001), SV (21.2 mL, P < 0.001), and EF (1.6%, P = 0.019) were significantly overestimated by DSCT when compared with 2D-TTE. An excellent correlation (r = 0.96, 0.97, 0.91, and 0.94, respectively, P < 0.001) between DSCT and CMR was seen in the evaluation of EDV, ESV, SV, and EF. EDV (15.9 mL, P < 0.001), ESV (7.3 mL, P < 0.001), and SV

    2017-05-01

    Full Text Available The carcinoid syndrome is rare but it is associated with carcinoid heart disease in more than a half of the cases. Carcinoid heart disease is typically characterised by morphological and functional modifications of right-sided valves. Its aetiology is probable multifactorial but serotonin appears to play a key role in the development of this valvular disease. Unlike gastrointestinal neuroendocrine tumours, ovarian neuroendocrine tumours can present with carcinoid syndrome and carcinoid heart disease in the absence of liver metastases; such ovarian neuroendocrine tumours are a unique clinical entity. The additional burden of cardiac impairment in these patients represents a significant reduction in survival. Early recognition and surgical valve replacement before advanced heart failure is established may improve the clinical outcome. We report the case of a woman with an ovarian neuroendocrine tumour and highly symptomatic carcinoid heart disease who was submitted to tumour resection followed by valvuloplasty. She demonstrated an outstanding clinical improvement and has remained free of tumour and symptomatology.

    2017-02-01

    We report the case of an 82-year-old man presenting with ventricular fibrillation (VF) occurring acutely after atrioventricular node (AVN) ablation. This patient had severe valvular cardiomyopathy, chronic atrial fibrillation (AF), and underwent prior to the AVN ablation a biventricular implantable cardiac defibrillator positioning. The VF was successfully cardioverted with one external electrical shock. What makes this presentation original is that the pre-ablation spontaneous heart rate in AF was slow (84 bpm), and that VF occurred after ablation despite a minimal heart rate drop of only 14 bpm. VF is the most feared complication of AVN ablation, but it had previously only been described in case of acute heart rate drop after ablation of at least 30 bpm (and more frequently>50 bpm). This case report highlights the fact that VF may occur after AVN ablation regardless of the heart rate drop, rendering temporary fast ventricular pacing mandatory whatever the pre-ablation heart rate.

Mental status was assessed by means of the Hospital Anxiety and Depression Scale (HADS and the Copenhagen Burnout Inventory (CBI scale. The primary outcome assessed was change in mental status of patients post-metoprolol treatment and the association with reduction in HR achieved by metoprolol.Results: A total of 154 patients (median age: 66.39 years; males: n=101 were divided into eight groups on the basis of their mental status. HR decreased significantly from baseline values in all the groups to <70 bpm in the 12th month, P≤0.0001. The HADS depression and CBI scores significantly increased from baseline throughout the study frame (P≤0.0001 for all groups, but a significant decrease in the HADS anxiety score was observed in patients with anxiety (P≤0.0001 for all groups. Regression analysis revealed no significant correlation in any of the groups between the HR reduction and the change in the HADS/CBI scores, except for a change in the CBI scores of CHF patients with depression (P=0.01, which was HR dependent.Conclusion: Metoprolol treatment worsens the depressive and high burnout

    To assess the prevalence of frailty syndrome in patients with heart rhythm disorders that qualified for pacemaker implantation. The study included 171 patients (83 women, aged 73.9 ± 6.7 years) who qualified for pacemaker implantation as a result of sinus node dysfunction (81 patients) or atrio-ventricular blocks (AVB; 90 patients). A total of 60 patients (25 women, aged 72.40 ± 7.09 years) without heart rhythm disorders were included in the control group. Frailty syndrome was diagnosed using the Canadian Study of Health and Aging Clinical Frailty Scale test. Frailty syndrome was diagnosed in 25.15% of the patients, and pre-frailty in 36.84% of the patients. Frailty syndrome was diagnosed in 10% of the control group, and the average value of frailty was 3.35 ± 0.92. Frailty occurred significantly more often among patients with AVB (33.34%) compared with patients who were diagnosed with sinus node dysfunction (16.05%); P = 0.0081. The average score of frailty for sinus node dysfunction was 3.71 ± 0.89, and for AVB it was 4.14 ± 0.93; P = 0.0152. In the case of AVB, the women had a statistically more intense level of frailty of 4.54 ± 0.90 as compared with the men 3.87 ± 0.85; P = 0.0294. In the multiple logistic analysis, the presence of any arrhythmia was strongly associated with frailty syndrome (OR 2.1286, 95% CI 1.4594 - 3.1049; P = 0.0001). Frailty syndrome was diagnosed in one-quarter of patients with cardiac arrhythmias, whereas a further 40% were at a higher risk of frailty syndrome, and its occurrence was significantly higher if compared with the control group. Frailty occurred significantly more often among patients with atrio-ventricular blocks, especially in women. The results of the present research showed that there is a statistical association between frailty and arrhythmias. Geriatr Gerontol Int 2017; 17: 1313-1318. © 2016 Japan Geriatrics Society.

    Depression has been associated with increased risk of heart failure (HF). Because anxiety is highly comorbid with depression, we sought to establish if anxiety, depression, or their co-occurrence is associated with incident HF. A retrospective cohort (N = 236,079) including Veteran's Administration patients (age, 50-80 years) free of cardiovascular disease (CVD) at baseline was followed up between 2001 and 2007. Cox proportional hazards models were computed to estimate the association between anxiety disorders alone, major depressive disorder (MDD) alone, and the combination of anxiety and MDD, with incident HF before and after adjusting for sociodemographics, CVD risk factors (Type 2 diabetes, hypertension, hyperlipidemia, obesity), nicotine dependence/personal history of tobacco use, substance use disorders (alcohol and illicit drug abuse/dependence), and psychotropic medication. Compared with unaffected patients, those with anxiety only, MDD only, and both disorders were at increased risk for incident HF in age-adjusted models (hazard ratio [HR] = 1.19 [ 95% confidence interval {CI} = 1.10-1.28], HR = 1.21 [95% CI = 1.13-1.28], and HR = 1.24 [95% CI = 1.17-1.32], respectively). After controlling for psychotropics in a full model, the association between anxiety only, MDD only, and both disorders and incident HF increased (HRs = 1.46, 1.56, and 1.74, respectively). Anxiety disorders, MDD, and co-occurring anxiety and MDD are associated with incident HF in this large cohort of Veteran's Administration patients free of CVD at baseline. This risk of HF is greater after accounting for protective effects of psychotropic medications. Prospective studies are needed to clarify the role of depression and anxiety and their pharmacological treatment in the etiology of HF.

    Full Text Available Background. 47XYY syndrome is a rare sex chromosome variation characterized by an additional Y chromosome. Most patients with 47XYY karyotype have normal phenotype. This disorder seems associated with a higher risk of developing behavioral and cognitive problems, tall stature, and infertility in adulthood. Sexual development disorder is a rare finding. We report a first case with an abnormal left coronary artery originating from the pulmonary artery in a 47XYY patient. Case. A one-month-old child was referred for ectopic testis and micropenis. Physical examination revealed facial dysmorphia, micropenis, and curvature of the penis with nonpalpable testis. Laboratory tests showed decreased total testosterone and anti-Mullerian hormone (AMH levels. Blood karyotyping revealed a 47XYY chromosomal formula. At the age of 3 months, the patient developed dyspnea and tachycardia. Echocardiography revealed an anomalous left coronary artery from pulmonary artery with left ventricular dysfunction requiring surgical revascularization by direct reimplantation of the left coronary artery system. Our second case was a 3-year-old child referred for hypospadias with nonpalpable left testicle. Physical examination showed hypertelorism. Blood karyotyping revealed a 47XYY chromosomal formula. Conclusion. To our knowledge, this is the first case of 47XYY syndrome associated with this congenital heart malformation and a sexual development disorder.

    A 19-year-old male African penguin ( Spheniscus demersus ) was presented with coelomic distention after a 6-week history of lethargy and decreased appetite. Results of radiographs showed loss of coelomic detail, and ultrasound and computed tomography results revealed coelomic fluid and dilated hepatic veins. Echocardiography revealed moderate right atrial enlargement. Findings were consistent with right-sided cardiac disease. Treatment with furosemide initially reduced ascites, but the clinical condition worsened weeks later and enalapril, pimobendan, and sildenafil were added to the medical therapy. At 12 weeks after presentation, results of an echocardiogram revealed persistent right atrioventricular valve regurgitation, moderate ascites, and dilation of hepatic veins. Clinical signs of right heart failure were managed through adjustments in medical therapy and coelomic fluid aspiration, but the bird died 18 weeks after initial presentation. Gross and microscopic findings were consistent with valvular insufficiency and right-sided heart failure. To our knowledge, this case is the first documented report of cardiac disease in an African penguin.

    In a retrospective series of 960 cases of tricuspid regurgitation studied by two-dimensional echocardiography 6 patients presented a systolic defect of valvular coaptation. The origin of this defect varied: one case was due to carcinoid, two to rheumatic cardiopathy, two to papyraceous right ventricle and one to sclerodermia associated with pulmonary arterial hypertension. The mechanism of the lacking coaptation varies according to the etiology: valvular retraction in carcinoid cardiopathy, right-ventricle dilatation, dilatation of the tricuspid ring and altered kinetics of the right ventricle in the other cases. Changed contractility of the right ventricle is the only element allowing to distinguish tricuspid regurgitation with and without a coaptation defect. Clinically this abnormality always points to an advanced stage of severe tricuspid regurgitation.

    Analysis of clinical data and results of retrograde femoral and popliteal phlebographics in 108 patients with varicose disease of the lower limbs permitted the authors to propose a three-stage classification of valvular insufficiency of the deep veins and to demonstrate that the disease compensation stages are related to the presence and degree of retrograde blood flow. Analysis of retrograde phlebograms helped single out 8 variants of retrograde blood flow in the deep femoral veins and 12 variants in the deep veins of the shin with valvular insufficiency thereof, which is practically important for interpretation of x-ray findings and for the choice of the optimal method and volume of surgical correction of this vascular abnormality. 4 refs.; 5 figs

    The Food and Drug Administration (FDA) criteria for diagnosis of drug-induced valvular heart disease (DIVHD) are only based on the observation of aortic regurgitation ≥ mild and/or mitral regurgitation ≥ moderate. We sought to evaluate the diagnostic value of FDA criteria in a cohort of control patients and in a cohort of patients exposed to a drug (benfluorex) known to induce VHD. This prospective, multicentre study included 376 diabetic control patients not exposed to valvulopathic drugs and 1000 subjects previously exposed to benfluorex. Diagnosis of mitral or aortic DIVHD was based on a combined functional and morphological echocardiographic analysis of cardiac valves. Patients were classified according to the FDA criteria [mitral or aortic-FDA(+) and mitral or aortic-FDA(-)]. Among the 376 control patients, 2 were wrongly classified as mitral-FDA(+) and 17 as aortic-FDA(+) (0.53 and 4.5% of false positives, respectively). Of those exposed to benfluorex, 48 of 58 with a diagnosis of mitral DIVHD (83%) were classified as mitral-FDA(-), and 901 of the 910 patients (99%) without a diagnosis of the mitral DIVHD group were classified as mitral-FDA(-). All 40 patients with a diagnosis of aortic DIVHD were classified as aortic-FDA(+), and 105 of the 910 patients without a diagnosis of aortic DIVHD (12%) were classified aortic-FDA(+). Older age and lower BMI were independent predictors of disagreement between FDA criteria and the diagnosis of DIVHD in patients exposed to benfluorex (both P ≤ 0.001). FDA criteria solely based on the Doppler detection of cardiac valve regurgitation underestimate for the mitral valve and overestimate for the aortic valve the frequency of DIVHD. Therefore, the diagnosis of DIVHD must be based on a combined echocardiographic and Doppler morphological and functional analysis of cardiac valves.

  10. Physiopathological approach to infective endocarditis in chronic hemodialysis patients: left heart versus right heart involvement.

    2017-11-01

    Infectious endocarditis (IE), a complication that is both cardiac and infectious, occurs frequently and is associated with a heavy burden of morbidity and mortality in chronic hemodialysis patients (CHD). About 2-6% of chronic hemodialysis patients develop IE and the incidence is 50-60 times higher among CHD patients than in the general population. The left heart is the most frequent location of IE in CHD and the different published series report a prevalence of left valve involvement varying from 80% to 100%. Valvular and perivalvular abnormalities, alteration of the immune system, and bacteremia associated with repeated manipulation of the vascular access, particularly central venous catheters, comprise the main factors explaining the left heart IE in CHD patients. While left-sided IE develops in altered valves in a high-pressure system, right-sided IE on the contrary, generally develops in healthy valves in a low-pressure system. Right-sided IE is rare, with its incidence varying from 0% to 26% depending on the study, and the tricuspid valve is the main location. Might the massive influx of pathogenic and virulent germs via the central venous catheter to the right heart, with the tricuspid being the first contact valve, have a role in the physiopathology of IE in CHD, thus facilitating bacterial adhesion? While the physiopathology of left-sided IE entails multiple and convincing mechanisms, it is not the case for right-sided IE, for which the physiopathological mechanism is only partially understood and remains shrouded in mystery.

Methods From June 2004 to June 2015, 28 patients (15 males and 13 females with ages ranging from 44 to 67 years (55.6±6.5 years with recurrent heart valve disease underwent resurgery. The reasons for resurgery included perivalvular leakage (7 cases, bioprosthetic valve decline (6 cases in mitral valve and 3 in tricuspid valve, mechanical prostheses dysfunction (2cases, infective endocarditis after valve replacement (2 cases, restenosis of repaired native valve (1 case, and severe tricuspid insufficiency after left-side valve surgery (7 cases. Resurgery included mitral valve replacement in 18 patients and tricuspid valve replacement in 10. All the patients underwent third or fourth or even fifth cardiac surgery for valve replacement. Results There were 2 hospital deaths with a mortality of 7.1% (2/28. The main causes of early-stage deaths were low cardiac output syndrome. The main postoperative complications were respiratory failure in 3, low cardiac output syndrome in 2, reexploration for bleeding in 2 and serious infectious shock in 1. All the patients were found with the great improvement in heart function and the re-implanted prostheses worked well during follow-up. Conclusions Although resurgery for recurrent heart valve disease poses a continuing challenge to cardiac surgeon, it could be performed with the satisfactory results. The keys to a successful cardiac resurgery include appropriate operational timing, refined surgical technique and reasonable perioperative managements. DOI: 10.11855/j.issn.0577-7402.2017.01.11

    Considering the historical and academic relevance of the Brazilian Archives of Cardiology (ABC), as its MEDLINE indexing began in 1950, it was assumed as a hypothesis that the analysis of the publications over the last 60 years could reflect the changing trends of heart disease in Brazil. The study data were collected using a program developed for this purpose, allowing the automatic extraction of information from the MEDLINE database. The study information were collected by searching 'Brazilian Archives of Cardiology AND selected parameter in English'. Four observational groups were determined: (1) major groups of heart diseases (coronary artery disease, valvular heart disease, congenital heart disease and cardiomyopathies); (2) relevant diseases in clinical practice (cardiac arrhythmias, cor pulmonale, myocardial infarction and congestive heart failure); (3) cardiovascular risk factors (hypertension, diabetes, dyslipidemia and atherosclerosis); and (4) group determined due to the growing trend of publications on congestive heart failure seen in previous groups (congestive heart failure, myocardial infarction, rheumatic heart disease and Chagasic heart disease) All publications within the established groups were described, highlighting the increasing importance of heart failure and diabetes as risk factors. A relatively easy search was carried out, using the computer program developed for literature search covering six decades. Emphasizing the limitations of the study, we suggest the existence of an epidemiological link between cardiac diseases that are prevalent in Brazil and the publications of the Brazilian Archives of Cardiology.

    Background We aimed to investigate whether the psychopathological symptoms and temperament-character dimensions observed in patients operated due to coronary artery disease (CAD) or valvular heart disease (VHD) differ among the patients and from healthy individuals. Methods Study population was composed of subjects with CAD, VHD and healthy controls (n = 50 in each group). Socio-demographic questionnaire, temperament and character inventory (TCI) and symptom check list-90-R (SCL-90-R) were applied to all groups. Groups were compared about temperament-character dimensions and scores of subscales of SCL-90-R. Results Harm avoidance was found to be higher in VHD group than those with CAD and, lower in healthy controls than both patient groups (P = 0.004). Reward dependence was similar among both patient groups and, was higher than healthy group (P = 0.015). Depression, anxiety, somatization, obsession and interpersonal sensitivity were found to be similar in both patient groups but they were higher than those in controls (P < 0.001, P < 0.001, P < 0.001, P = 0.002 and P = 0.003, respectively). Phobia was seen equally in CAD group and healthy controls and, was found to be lower in these than in VHD (P = 0.009). Anger score was in descending order in patients with VHD, CAD and healthy controls group (P = 0.010 and 0.001). Paranoia was in descending order in patients with VHD, CAD and controls (P = 0.015 and 0.001). A weak and inverse correlation was found between ejection fraction (EF) and the persistence dimension of temperament scaled by TCI in patients with VHD (r = -0.276, P = 0.052). An inverse correlation was observed between EF and the reward dependence dimension in CAD group (r = -0.195, P = 0.044). In patients with VHD, EF demonstrated an inversely weak (r = -0.289, P = 0.042), moderate (r = -0.360, P = 0.010) and strong (r = -0.649, P < 0.001) correlation with inter-personal sensitivity, phobia and paranoia, respectively.

    Cardiac ventriculography has been used extensively to define the anatomy of the ventricles and related structures in patients with congenital, valvular, coronary, and cardiomyopathic heart disease. Specifically, left ventriculography may provide valuable information about global and segmental left ventricular function, mitral valvular incompetence, and the presence, location, and severity of a number of other abnormalities, including ventricular septal defect and hypertrophic cardiomyopathy. As a result, it should be a routine part of catheterization in patients being evaluated for coronary artery disease, aortic or mitral valvular disease, unexplained left ventricular failure, or congenital heart disease. Similarly, right ventriculography may provide information about global and segmental right ventricular function and can be especially helpful in patients with congenital heart disease

    Certain cardiovascular risk factors have been linked to morbidity and mortality in heart transplant (HT) patients. The sum of various risk factors may have a large cumulative negative effect, leading to a substantially worse prognosis and the need to consider whether HT is contraindicated. The objective of this study was to determine whether the risk factors usually available prior to HT result in an excess mortality in our setting that contraindicates transplantation. Consecutive patients who underwent heart transplantation from November 1987 to January 2004 were included. Heart-lung transplants, retransplants, and pediatric transplants were excluded. Of the 384 patients, 89% were men. Mean age was 52 years (range, 12 to 67). Underlying disease included ischemic heart disease (52%), idiopathic dilated cardiomyopathy (36%), valvular disease (8%), and other (4%). Variables considered risk factors were obesity (BMI >25), dyslipidemia, hypertension, prior thoracic surgery, diabetes, and history of ischemic heart disease. Survival curves by number of risk factors using Kaplan-Meier and log-rank for comparison of curves. Overall patient survival at 1, 5, 10, and 13 years was 76%, 68%, 54%, and 47%, respectively. Survival at 10 years, if fewer than two risk factors were present, was 69%; 59% if two or three factors were present; and 37% if more than three associated risk factors were present (P = .04). The presence of certain risk factors in patients undergoing HT resulted in lower survival rates. The combination of various risk factors clearly worsened outcomes. However, we do not believe this should be an absolute contraindication for transplantation.

  19. Sleep-Disordered Breathing in Heart Failure - A Therapeutic Dilemma.

    Science.gov (United States)

    Haruki, Nobuhiko; Floras, John S

    2017-06-23

    Sleep-disordered breathing (SDB) occurs in approximately 50% of patients with reduced left ventricular ejection fraction receiving contemporary heart failure (HF) therapies. Obstructive (OSA) and central sleep apneas (CSA) interrupt breathing by different mechanisms but impose qualitatively similar autonomic, chemical, mechanical, and inflammatory burdens on the heart and circulation. Because contemporary evidence-based drug and device HF therapies have little or no mitigating effect on the acute or long-term consequences of such stimuli, there is a sound mechanistic rationale for targeting SDB to reduce cardiovascular event rates and prolong life. However, the promise of observational studies and randomized trials of small size and duration describing a beneficial effect of treating SDB in HF via positive airway pressure was not realized in 2 recent randomized outcome-driven trials: SAVE, which evaluated the cardiovascular effect of treating OSA in a cohort without HF, and SERVE-HF, which reported the results of a strategy of random allocation of minute-ventilation-triggered adaptive servo-ventilation (ASV) for HF patients with CSA. Whether effective treatment of either OSA or CSA improves the HF trajectory by reducing cardiovascular morbidity or mortality has yet to be definitively established. ADVENT-HF, designed to determine the effect of treating both CSA and non-sleepy OSA HF patients with a peak-airflow triggered ASV algorithm, could resolve this present clinical equipoise concerning the treatment of SDB.

    An association between N-terminal prohormone brain natriuretic peptide (NT-proBNP) and exercise tolerance in patients with valvular heart disease (VHD) has been suggested; however, there are few data available regarding this relation. The aim of this study is to evaluate the correlation between exercise tolerance and NT-proBNP in patients with asymptomatic or mildly symptomatic significant VHD and normal left ventricular ejection fraction (LV EF). A total of 96 patients with asymptomatic or mildly symptomatic VHD and normal LV EF (≥50%) underwent cardiopulmonary exercise echocardiography. NT-proBNP levels were determined at baseline and after exercise in 3 hours. Patients were divided in 2 groups based on lower (left atrial volume index before exercise, right ventricular systolic pressure before exercise, E velocity after exercise, and E/e' ratio after exercise varied significantly. In addition, peak VO 2 was inversely related to NT-proBNP before (r = -0.352, p left atrial volume index, E/e' ratio, and right ventricular systolic pressure before and after exercise. NT-proBNP after exercise was also directly related to the same parameters. NT-proBNP levels both before and after exercise were higher in the group with lower exercise tolerance. In conclusion, through the correlation among exercise tolerance, NT-proBNP, and parameters of diastolic dysfunction, we demonstrated that diastolic dysfunction and NT-proBNP could predict exercise tolerance in patients with significant VHD and normal LV EF.

    There is a wide variation (13% to 74%) in the reported prevalence of heart failure associated with normal left ventricular (LV) systolic function (diastolic heart failure). There is no published information on this condition in China. To ascertain the prevalence of diastolic heart failure in this community, 200 consecutive patients with the typical features of congestive heart failure were studied with standard 2-dimensional Doppler echocardiography. A LV ejection fraction (LVEF) >45% was considered normal. The results showed that 12.5% had significant valvular heart disease. Of the remaining 175 patients, 132 had a LVEF >45% (75%). Therefore, 66% of patients with a clinical diagnosis of heart failure had a normal LVEF. Heart failure with normal LV systolic function was more common than systolic heart failure in those >70 years old (65% vs 47%; p = 0.015). Most (57%) had an abnormal relaxation pattern in diastole and 14% had a restrictive filling pattern. In the systolic heart failure group, a restrictive filling pattern was more common (46%). There were no significant differences in the sex distribution, etiology, or prevalence of LV hypertrophy between these 2 heart failure groups. In conclusion, heart failure with a normal LVEF or diastolic heart failure is more common than systolic heart failure in Chinese patients with the symptoms of heart failure. This may be related to older age at presentation and the high prevalence of hypertension in this community.

    Rheumatic Heart Disease (RHD) continues to be a major public health problem in developing countries like Pakistan. Objective of this cross sectional-analytical study was to analyze the severity of valvular lesions on echocardiography in patients pre-diagnosed with RHD. Methods: The trans thoracic echocardiographic records of RHD patients from 2004 to 2008 were retrospectively reviewed for type and degree of valvular involvement according to AHA/ACC guidelines. Results: A total of 13,414 patients [7,219 Males (53.8%), 6,195 Females (46.2%)]ranging from 11 to 90 years with a mean age of 42.33 +- 18.976 were studied. On echocardiography, 7,500 (56%) had mitral regurgitation (8.8% severe MR), 6,449(48.2%) had tricuspid regurgitation (7.1% severe TR) and 5,550 (41.4%) had aortic regurgitation (4.8% severe AR). MS was detected in 2,729 (20.3%) patients (15.3% severe MS), AS in 102 (0.8%) and TS in 31 (0.2%) patients. Mixed mitral valve disease was seen in 3,185 (23.7%), mixed aortic valve disease in 222 (1.7%) and mixed tricuspid valve disease in 47 (0.4%) patients. All three valves were involved in 2,826 (21.06%) patients, combination of mitral and aortic valves in 3,103 (23.13%), mitral and tricuspid in 3,784 (28.2 %), and mitral only in 3,701 (27.59%) patients. There was some mitral valve abnormality in all patients. Conclusion: Mitral valve was most commonly affected, while regurgitant lesions were more common than stenotic lesions, and most severe in younger patients. All valvular lesions had almost an equal distribution among the sexes, except aortic regurgitation, which was more common in females. Therefore, echocardiography should be done routinely for patients with RHD, focusing on younger population, to facilitate diagnosis and definitive treatment before complications set in. (author)

    Heart disease is one of the leading causes of morbidity and mortality worldwide and it has been well established that it is associated with both mental and physical conditions. This paper describes the prevalence of heart disease with mental disorders and other chronic physical conditions among the Singapore resident population. Data were from the Singapore Mental Health Study which was a representative, cross-sectional epidemiological survey undertaken with 6616 Singapore residents, between December 2009 and December 2010. The Composite International Diagnostic Interview Version 3.0 was used to establish the diagnosis of mental disorders, while a chronic medical conditions checklist was used to gather information on 15 physical conditions, including various forms of heart disease. Health-related quality of life was measured using the Euro-Quality of Life Scale (EQ-5D). The lifetime prevalence of heart disease was 2.8%. Socio-demographic correlates of heart disease included older age, Indian ethnicity, secondary education (vs. tertiary) and being economically inactive. After adjusting for socio-demographic variables and other comorbid physical and mental disorders, the prevalence of major depressive disorder and bipolar disorder were significantly higher among those with heart disease, as were diabetes, arthritis, kidney failure and lung disease. These findings highlight important associations between heart disease and various socio-demographic correlates, mental disorders and physical conditions. Given the high prevalence of mood disorders among heart disease patients, timely and appropriate screening and treatment of mental disorders among this group is essential.

    Full Text Available Abstract Transthoracic echocardiography is a primary non-invasive modality for investigation of heart transplant recipients. It is a versatile tool which provides comprehensive information about cardiac structure and function. Echocardiographic examinations can be easily performed at the bedside and serially repeated without any patient's discomfort. This review highlights the usefulness of Doppler echocardiography in the assessment of left ventricular and right ventricular systolic and diastolic function, of left ventricular mass, valvular heart disease, pulmonary arterial hypertension and pericardial effusion in heart transplant recipients. The main experiences performed by either standard Doppler echocardiography and new high-tech ultrasound technologies are summarised, pointing out advantages and limitations of the described techniques in diagnosing acute allograft rejection and cardiac graft vasculopathy. Despite the sustained efforts of echocardiographic technique in predicting the biopsy state, endocardial myocardial biopsies are still regarded as the gold standard for detection of acute allograft rejection. Conversely, stress echocardiography is able to identify accurately cardiac graft vasculopathy and has a recognised prognostic in this clinical setting. A normal stress-echo justifies postponement of invasive studies. Another use of transthoracic echocardiography is the monitorisation and the visualisation of the catheter during the performance of endomyocardial biopsy. Bedside stress echocardiography is even useful to select appropriately heart donors with brain death. The ultrasound monitoring is simple and effective for monitoring a safe performance of biopsy procedures.

    The aim of this study is to define the predictors of chronic carditis in patients with acute rheumatic carditis (ARC). Patients diagnosed with ARC between May 2010 and May 2011 were included in the study. Echocardiography, electrocardiography, lymphocyte subset analysis, acute phase reactants, plasma albumin levels, and antistreptolysin-O (ASO) tests were performed at initial presentation. The echocardiographic assessments were repeated at the sixth month of follow-up. The patients were divided into two groups according to persistence of valvular pathology at 6th month as Group 1 and Group 2, and all clinical and laboratory parameters at admission were compared between two groups of valvular involvement. During the one-year study period, 22 patients had valvular disease. Seventeen (77.2%) patients showed regression in valvular pathology. An initial mild regurgitation disappeared in eight patients (36.3%). Among seven (31.8%) patients with moderate regurgitation initially, the regurgitation disappeared in three, and four patients improved to mild regurgitation. Two patients with a severe regurgitation initially improved to moderate regurgitation (9.1%). In five (22.8%) patients, the grade of regurgitation [moderate regurgitation in one (4.6%), and severe regurgitation in 4 (18.2%)] remained unchanged. The albumin level was significantly lower at diagnosis in Group 2 (2.6±0.48g/dL). Lymphocyte subset analysis showed a significant decrease in the CD8 percentage and a significant increase in CD19 percentage at diagnosis in Group 2 compared to Group 1. The blood albumin level and the percentage of CD8 and CD19 (+) lymphocytes at diagnosis may help to predict chronic valvular disease risk in patients with acute rheumatic carditis. Copyright © 2016.

  10. Pathophysiologic aspects of the development of cognitive disorders in chronic heart failure in elderly patients

    Full Text Available The present literature review presents current views on pathophysiologic aspects of the formation and progression of cognitive disorders in chronic heart failure in elderly patients. Advanced age itself is an important predictor of the development of cardiovascular, neurodegenerative and other diseases. Involutive changes of cardiovascular system are known to potentiate the development of chronic heart failure. Heart failure in older people usually develops gradually. Formation of the cognitive deficit in heart disease is associated with chronic cerebral ischemia as well as a cascade of neurochemical processes occurring in the brain, eventually forming a vicious circle. Often the symptoms of cerebral ischemia due to reduced stroke volume occur much earlier than congestion signs in other organs and systems. Chronic cerebral ischemia that occurs due to violation of cerebral hemodynamics, is associated with both extracerebral and intracerebral causes, which in turn contributes to the development of chronic brain hypoxia and aggravation of cognitive dysfunction. Thus, the features of the development and course of disease in people of older age groups indicate that in geriatric practice existing diagnostic schemes are not always applicable. When observing patients of elderly and senile age with chronic heart failure, during the assessment of their condition and running diagnostic tests, special attention should be payed to the earliest detection of cognitive dysfunction signs in order to correct the patient's treatment and improve quality of life.

    Full Text Available Background: Major depressive disorder (MDD is associated with increased heart rate and reductions in its variability (HRV – markers of future morbidity and mortality – yet prior studies have reported contradictory effects. We hypothesised that increases in heart rate and reductions in HRV would be more robust in melancholia relative to controls, than in patients with non-melancholia. Methods: A total of 72 patients with a primary diagnosis of MDD (age M: 36.26, SE: 1.34; 42 females and 94 controls (age M: 35.69, SE: 1.16; 52 females were included in this study. Heart rate and measures of its variability (HRV were calculated from two 2-minute electrocardiogram recordings during resting state. Propensity score matching controlled imbalance on potential confounds between patients with melancholia (n=40 and non-melancholia (n=32 including age, gender, disorder severity and comorbid anxiety disorders. Results: MDD patients with melancholia displayed significantly increased heart rate and lower resting-state HRV (including the square root of the mean squared differences between successive N–N intervals, the absolute power of high frequency and standard deviation of the Poincaré plot perpendicular to the line of identity measures of HRV relative to controls, findings associated with a moderate effect size (Cohens d’s = 0.56-0.58. Patients with melancholia also displayed an increased heart rate relative to those with non-melancholia (Cohen’s d = 0.20.Conclusion: MDD patients with melancholia – but not non-melancholia – display robust increases in heart rate and decreases in HRV. These findings may underpin a variety of behavioural impairments in patients with melancholia including somatic symptoms, cognitive impairment, reduced responsiveness to the environment, and over the longer-term, morbidity and mortality.

Statistical analysis of data obtained was done using SPSS 16. Results: The total number of attendees of all the medical outpatient clinics during the 9-year period was 67,378, with a subset of 9423 attending the cardiology clinic. There were 11 cases of RHD, which translates to a prevalence of 0.16/1000 and 1.2/1000 for medical outpatient clinics and the cardiology clinic respectively. The mean age of the patients was 25.64 ± 9.65 years, age range 14–40 years and male to female ratio of 1:1.2. The most common valve affected was mitral (90.9%, followed by the aortic (36.4%, and the tricuspid (18.2%. Mitral and aortic lesions coexisted in 18.2% of the patients, and late presentation was common in all RHD cases. Heart failure was the most common complication (90.9%. Other complications were secondary pulmonary hypertension (36.4%, infective endocarditis (27.3%, atrial fibrillation (27.3%, cardioembolic cerebrovascular disease (18.2%, and atrial flutter (9.1%.

    Biological heart valve prostheses are characterized by a limited durability due to the degenerative processes after implantation. Tissue engineering may provide new approaches in the development of optimized valvular grafts. While re-endothelialization of decellularized heart valves has already been successfully implemented, interstitial repopulation still remains an unaccomplished objective although it is essential for valvular functionality and regeneration potential. The aim of this study was to compare different concepts for an improved in vitro interstitial repopulation of decellularized heart valves. A novel 3D heart valve model has been developed to investigate the cell behaviour of valvular interstitial cells (VIC) in their physiological environment and to evaluate the potential of in vitro repopulation of acellular heart valves. Ovine aortic heart valves were decellularized by detergent solutions and additionally treated with trypsin or laser perforation. Subsequently, the decellularized extracellular matrices (dECM) were reseeded with ovine VIC using reseeding devices to provide a repopulation of the matrix on a defined area under controlled conditions. After an initial attachment of the VIC, reseeded dECM were transferred into a transwell system to improve the nutrient supply inside the valvular matrix. Cell migration and expression of cell markers were analysed histologically. The results were compared with VIC cultivation in a biological scaffold. VIC did not migrate into the matrix of untreated dECM and reseeding in laser perforated dECM showed inconsistent results. However, trypsinization increased the susceptibility of the valvular cusps to VIC penetration and repopulation of superficial areas. Additionally, the cultivation of reseeded dECM in a transwell system significantly increased the total number of cells repopulating the valvular matrix and their mean migration distance, representing the best repopulation results.

    Full Text Available Aim: The objective of this study is to investigate the improvement of heart function in dogs with chronic valvular heart disease after puppy deciduous teeth stem cells (pDSCs administration. Materials and Methods: 20 client-owned dogs with degenerative valvular heart disease underwent multiple intravenous injections of allogeneic pDSCs. Dogs were randomly assigned to two groups: (i Control group (n=10 with standard treatment for heart failure and (ii group with standard treatment and multiple administrations of pDSCs (n=10. Electrocardiography, complete transthoracic echocardiography, thoracic radiography, and blood pressure were recorded before and after pDSCs injections for 15, 30 and 60 days. Results: Post pDSCs injection showed measurable improvement in left ventricular ejection fraction, American College of Veterinary Internal Medicine (ACVIM functional class significantly improved and improved quality of life scores were observed. In the control group, there were no significant enhancements in heart function or ACVIM class. Conclusions: This finding suggests that pDSCs could be a supplement for valvular heart disease treatment.

    The development of artificial hearts in patients with end-stage heart disease have been confronted with the major issues of thromboembolism or haemorrhage. Since valvular bioprostheses are associated with a low incidence of these complications, we decided to use bioprosthetic materials in the construction of a novel artificial heart (C-TAH). We report here the device characteristics and its first clinical applications in two patients with end-stage dilated cardiomyopathy. The aim of the study was to evaluate safety and feasibility of the CARMAT TAH for patients at imminent risk of death from biventricular heart failure and not eligible for transplant. The C-TAH is an implantable electro-hydraulically actuated pulsatile biventricular pump. All components, batteries excepted, are embodied in a single device positioned in the pericardial sac after excision of the native ventricles. We selected patients admitted to hospital who were at imminent risk of death, having irreversible biventricular failure, and not eligible for heart transplantation, from three cardiac surgery centres in France. The C-TAH was implanted in two male patients. Patient 1, aged 76 years, had the C-TAH implantation on Dec 18, 2013; patient 2, aged 68 years, had the implantation on Aug 5, 2014. The cardiopulmonary bypass times for C-TAH implantation were 170 min for patient 1 and 157 min for patient 2. Both patients were extubated within the first 12 postoperative hours and had a rapid recovery of their respiratory and circulatory functions as well as a normal mental status. Patient 1 presented with a tamponade on day 23 requiring re-intervention. Postoperative bleeding disorders prompted anticoagulant discontinuation. The C-TAH functioned well with a cardiac output of 4·8-5·8 L/min. On day 74, the patient died due to a device failure. Autopsy did not detect any relevant thrombus formation within the bioprosthesis nor the different organs, despite a 50-day anticoagulant-free period. Patient 2

    To determine the frequency of different disorders requiring warfarin therapy and to see the target INR and warfarin dose requirement in Pakistani population. Study Design:Descriptive study. Setting and Duration of Study: The study was carried out at Armed Forces Institut e of Cardiology (AFIC) Rawalpindi, Military Hospital Rawalpindi and National Institute of Cardiovascular Diseases (NICVD), Karachi, Pakistan from October 2010 to March 2012. Patients and Methods: Stable patients taking warfarin therapy were recruited after detailed medical history, physical examination and laboratory tests. The demographic and clinical data of individuals were entered in a pre-structured proforma. Patients suffering from hepatic and renal disease, any co-morbid disease or taking any concurrent medication or diet which would have affected warfarin therapy, were excluded. Data was analyzed using PSS version 20.0. Results: A total of 607 stable patients fulfilling the eligibility criteria, participated in the study. There were 297 (48.9%) male and 310 (51.1%) female patients. The mean age was 37.93 +- 12.23 years (range 18-65 years). The most common indication for warfarin therapy was valvular heart diseases (93.4%) followed by atrial fibrillation (2.3%) whereas other indications for warfarin use are less commonly seen in our study population. Patients had mean international normalized ratio (INR) value of 2.3 +9- 0.8 (range 1.5-3.5). Mean daily dose of warfarin calculated in 607 patients was 5.62 and 1.98 mg with the range of 0.36-15 g whereas mean weekly dose was 39.36 +- 13.8 mg with the range of 2.5-105 mg. Conclusion: In Pakistani population the most common indications for warfarin use are valvular heart diseases followed by atrial fibrillation. The mean INR values were within recommended range of 2-3. The mean daily dose observed in long-term therapy is comparable to the empirical dose of 5 mg routinely started in clinical practice. (author)

    The features of heart failure (HF) in Djibouti have not been well described. We sought to document the current patterns of HF here. We prospectively included Djiboutian adults hospitalized for HF in the French Military Hospital (Djibouti) from August 2008 through December 2010. Of 1688 adults hospitalized in the medical department, 45 (2.7%) had symptomatic HF: 38 (84%) men, mean age 55.8 years (range 27-75). Twenty-five (56%) patients were initially hospitalized for acute pulmonary edema. The underlying diseases included coronary artery disease (CAD) (62%), hypertensive heart disease (18%), rheumatic valvular disease (13%), and primary dilated cardiomyopathy (7%). Their cardiovascular risk factors included tobacco use (53%), hypertension (69%), diabetes (47%), and hypercholesterolemia (51%). Patients in the CAD group were older, and had diabetes more often (p<0.01). All khat chewers (53%) were males and smokers. Mean left ventricular ejection fraction (LVEF) was 39 ± 14%. During follow-up (14.4 ± 9 months), 8 (18%) patients died, 9 (20%) were again hospitalized for HF, and 3 (7%) had ischemic strokes. One month after discharge, the New York Heart Association (NYHA) class was II for 40%, III for 44%, and IV for 16%. Higher NYHA classes and dilated cardiomyopathy were both associated with poorer outcomes (p<0.03). In hospitalized Djiboutians, most HF patterns are similar to those in industrialized countries. CAD is more prevalent than previously reported in African patients with HF.

    To analyze the differential clinical characteristics according to gender of patients with heart failure in terms of etiology, comorbidity, triggers, treatment, hospital stay and overall mortality at one year. We employed data from the RICA registry, a multicenter prospective cohort of patients hospitalized in internal medicine departments for heart failure, with a follow-up of one year. We analyzed the differences between the gender in terms of the etiology of the heart disease, comorbidity, triggers, left ventricle ejection fraction, functional state, mental condition, treatment, length of stay and mortality at 1 year. A total of 1772 patients (47.2% men) were included. The women were older than the men (p<.001) and had a higher prevalence of hypertension, obesity, chronic kidney disease, atrial fibrillation and preserved left ventricle ejection fraction (p<.001). The men's medical history had a predominance of myocardial infarction, chronic obstructive pulmonary disease, peripheral arteriopathy (p<.001) and anemia (p=.02). In the women, a hypertensive etiology was predominant, followed by valvular. The main triggers were hypertension and atrial fibrillation. Treatment with beta-blockers, ACEIs and/or ARBs did not differ by sex. The women had poorer functional capacity (p<.001), according to the Barthel index. After adjusting for age and other prognostic factors, the mortality at one year was lower among the women (RR: 0.69; 95% CI 0.53-0.89; p=.004). HF in women occurs at a later age and with different comorbidities. The hypertensive and valvular etiology is predominant, with preserved left ventricle ejection fraction, and the age-adjusted mortality is lower than in men.

    Pulmonary perfusion scan with radioactive {sup 113m}In-iron hydroxide particle was performed in the 25 cases of heart disease which had been diagnosed by cardiac catheterization prior to surgery from July, 1972 to July, 1973 at the Department of Radiology and Nuclear Medicine, Yonsei Medical College. It consists of 7 mitral stenosis, 2 mitral insufficiency, 1 aortic insufficiency, 3 atrial septal defect, 5 ventricular septal defect, 2 patent ductus arteriosus, 1 transposition of great vessel and 4 Tetralogy of Fallot. Findings of pulmonary perfusion scan in relation to hemodynamic data of cardiac catheterization were examined. 1) Out of 10 cases of acquired valvular heart disease, In 6 cases of stenosis and 1 case of aortic insufficiency, radioactivity was increased at both upper lung. This finding is noted when pulmonary wedge or venous pressure was elevated above 22 mmHg and arterial systolic pressure above 33 mmHg. 2) Out of 15 cases of congenital heart disease. In almost all cases of artial septal defect and ventricular septal defect except 2 cases, radioactivity was even at both entire lung. In 2 cases of patent ductras arteriosus, radioactivity was decreased especially at the left lung. It is observed that in acyanotic congenital heart disease, radioactivity of lung is not related with pulmonary arterial pressure. In 3 cases of Tetralogy of Fallot, radioactivity was even at both entire lung and in 2 of them, extrapulmonary radioactivity of liver or kidney which depends on size of defect and volume of right to left shunt reversible, was noted.

In 2 cases of patent ductras arteriosus, radioactivity was decreased especially at the left lung. It is observed that in acyanotic congenital heart disease, radioactivity of lung is not related with pulmonary arterial pressure. In 3 cases of Tetralogy of Fallot, radioactivity was even at both entire lung and in 2 of them, extrapulmonary radioactivity of liver or kidney which depends on size of defect and volume of right to left shunt reversible, was noted.

    To explore ex vivo the role of bone morphogenetic protein-4 (BMP-4) and transforming growth factor-beta1 (TGF-β1) in acute valvular response to fluid shear stress (FSS) abnormalities. Porcine valve leaflets were subjected ex vivo to physiologic FSS, supra-physiologic FSS magnitude at normal frequency and supra-physiologic FSS frequency at normal magnitude for 48 h in a double-sided cone-and-plate bioreactor filled with standard culture medium. The role of BMP-4 and TGF-β1 in the valvular response was investigated by promoting or inhibiting the downstream action of those cytokines via culture medium supplementation with BMP-4 or the BMP antagonist noggin, and TGF-β1 or the TGF-β1 inhibitor SB-431542, respectively. Fresh porcine leaflets were used as controls. Each experimental group consisted of six leaflet samples. Immunostaining and immunoblotting were performed to assess endothelial activation in terms of intercellular adhesion molecule-1 and vascular cell adhesion molecule-1 expressions, paracrine signaling in terms of BMP-4 and TGF-β1 expressions and extracellular matrix (ECM) remodeling in terms of cathepsin L, cathepsin S, metalloproteinases (MMP)-2 and MMP-9 expressions. Immunostained images were quantified by normalizing the intensities of positively stained regions by the number of cells in each image while immunoblots were quantified by densitometry. Regardless of the culture medium, physiologic FSS maintained valvular homeostasis. Tissue exposure to supra-physiologic FSS magnitude in standard medium stimulated paracrine signaling (TGF-β1: 467% ± 22% vs 100% ± 6% in fresh controls, BMP-4: 258% ± 22% vs 100% ± 4% in fresh controls; P 0.05). Supra-physiologic FSS frequency had no effect on endothelial activation and paracrine signaling regardless of the culture medium but TGF-β1 silencing attenuated FSS-induced ECM degradation via MMP-9 downregulation (MMP-9: 302% ± 182% vs 100% ± 42% in fresh controls; P > 0.05). Valvular tissue is sensitive

    Background: Chronic congestive heart failure (CHF) in humans is associated with abnormal hemostasis, and abnormalities in hemostatic biomarkers carry a poor prognosis. Alterations in hemostatic pathways can be involved in the pathogenesis of CHF in dogs, and microthrombosis in the myocardium could...... contribute to increased mortality. Hypothesis: That plasma concentration or activity of hemostatic biomarkers is altered in dogs with CHF and that these factors predict mortality. Animals: Thirty-four dogs with CHF caused by either dilated cardiomyopathy (DCM, n = 14) or degenerative valvular disease (CDVD......, n = 20) compared with 23 healthy age-matched control dogs were included in this study. Dogs with CHF were recruited from 2 referral cardiology clinics, and control dogs were owned by friends or colleagues of the investigators. Methods: Clinical examination and echocardiography were performed in all...

    Full Text Available Introducción: La cirugía valvular mínimamente invasiva representa un cambio significativo en el tratamiento de las enfermedades valvulares. Este procedimiento se ha convertido en una opción de tratamiento que puede representar menos riesgos para el paciente, especialmente si se realiza en centros que han desarrollado experiencia con la técnica quirúrgica. Métodos: Revisión de la literatura y reporte de experiencia con la utilización del método descrito. Resultados: En cuanto a la incidencia de re-exploración por sangramiento, fibrilación auricular y eventos tromboembólicos no se encontró diferencia significativa entre la esternotomía media y la cirugía mínimamente invasiva pero con esta última se observó menor necesidad de transfusiones sanguíneas, menor incidencia de infecciones del esternón, al igual que menos dolor postoperatorio, corta permanencia en la unidad de cuidados intensivos y en el hospital, menos uso de analgésicos, mayor satisfacción del paciente, reducción en el uso de los servicios de rehabilitación y regreso a las actividades normales. Sin embargo, existe mayor número de accidentes cerebrovasculares asociados a la cirugía mínimamente invasiva. La mortalidad entre ambas técnicas es similar, excepto en pacientes de alto riesgo, en quienes se ha demostrado una reducción en la mortalidad con la cirugía mínimamente invasiva. Conclusiones: La cirugía de mínimo acceso se relaciona con recuperación más rápida y mayor satisfacción para el paciente, así como con reducción de complicaciones postoperatorias y de la mortalidad en pacientes de riesgo alto.

    2005-01-01

    Multislice spiral computed tomography (MSCT) is a rapidly evolving, noninvasive technique for cardiac imaging. Knowledge of the principle of electrocardiogram-gated MSCT and its limitations in clinical routine are needed to optimize image quality. Therefore, the basic technical principle including essentials of image postprocessing is described. Cardiac MSCT imaging was initially focused on coronary calcium scoring, MSCT coronary angiography, and analysis of left ventricular function. Recent studies also evaluated the ability of cardiac MSCT to visualize myocardial infarction and assess valvular morphology. In combination with experimental approaches toward the assessment of aortic valve function and myocardial viability, cardiac MSCT holds the potential for a comprehensive examination of the heart using one single examination technique

    Regulatory decisions regarding attention deficit hyperactivity disorder drug licensing and labelling, along with recent statements from professional associations, raise questions of practice regarding the evaluation and treatment of patients with attention deficit hyperactivity disorder. To address these issues for the European community, the European Network for Hyperkinetic Disorders, through its European Attention Deficit Hyperactivity Disorder Guidelines Group, organised a meeting between attention deficit hyperactivity disorder specialists, paediatric cardiovascular specialists, and representatives of the major market authorisation holders for attention deficit hyperactivity disorder medications. This manuscript represents their consensus on cardiovascular aspects of attention deficit hyperactivity disorder medications. Although sudden death has been identified in multiple young individuals on attention deficit hyperactivity disorder medication causing regulatory concern, when analysed for exposure using currently available data, sudden death does not appear to exceed that of the general population. There is no current evidence to suggest an incremental benefit to electrocardiography assessment of the general attention deficit hyperactivity disorder patient. Congenital heart disease patients have an increased prevalence of attention deficit hyperactivity disorder, and can benefit from attention deficit hyperactivity disorder therapies, including medication. The attention deficit hyperactivity disorder specialist is the appropriate individual to evaluate benefit and risk and recommend therapy in all patients, although discussion with a heart specialist is reasonable for congenital heart disease patients. For attention deficit hyperactivity disorder patients with suspected heart disease or risk factor/s for sudden death, assessment by a heart specialist is recommended, as would also be the case for a non-attention deficit hyperactivity disorder patient.

    the contents of the current review on syndecans in cardiac fibrosis. The heart is subjected to various forms of pathological stimuli, e.g., myocardial infarction, hypertension, valvular stenosis, infection, or an inherited genetic mutation, triggering responses in cells resident in the heart. Here, we focus on the responses of cardiac fibroblasts directing changes in the extracellular matrix resulting in cardiac fibrosis. A family of four transmembrane proteoglycans, syndecan-1 to -4, is expressed in the cell membrane of cardiac fibroblasts and is generally up-regulated in response to the above-mentioned pathological stimuli. Syndecans carry glycosaminoglycan chains on their extracellular domain, binding a plethora of molecules involved in fibrosis, e.g., growth factors, cytokines, immune cell adhesion proteins, and pathogens. Syndecans have a short cytoplasmic tail involved in pro-fibrotic signaling. The signaling and cellular processes governed by syndecans in the heart in response to pathological stimuli regulate important aspects of extracellular matrix remodeling and fibrosis and have mainly been studied in cardiac remodeling in response to cardiac infarction and pressure overload. In general, adequate timing and the quantity and quality of fibrosis are absolutely crucial for heart function and survival, determining cardiac stiffness, contractility, compliance, probability of rupture, dilation, and diastolic and systolic function. Syndecan-1 and -4 have mainly been studied in the heart and are discussed in this review (LV left ventricle).

    To (1) report the prognostic association between anxiety disorder subtypes and major adverse cardiac events (MACE), (2) report anxiety disorder prevalence in coronary heart disease (CHD), and (3) report the efficacy of anxiety disorder treatments in CHD. A comprehensive electronic database search was performed in November 2013 for studies reporting anxiety disorder prevalence according to structured interview in CHD samples or MACE, and randomized controlled trials (RCTs) comparing anxiety disorder treatment with placebo or usual care. From 4041 articles 42 samples were selected for extraction (8 for MACE prognosis, 39 for prevalence, no RCTs were eligible). Five generalized anxiety disorder (GAD) studies reported 883 MACE events (combined n=2851). There was a non-significant association between GAD and MACE (risk ratio=1.20, 95% CI .86-1.68, P=.28) however the effect size was highly significant in outpatient samples (adjusted hazard ratio=1.94, 95% CI 1.45-2.60, Pversus DSM-IV taxonomies. The paucity of extant anxiety disorder RCTs, alongside MACE risk for GAD outpatients, should stimulate further anxiety disorder intervention in CHD populations. Research should focus on depression and anxiety, thereby unraveling disorder specific and more generic pathways. Copyright © 2014 Elsevier Inc. All rights reserved.

    Fifteen patients and three volunteers underwent radionuclide blood-pool cardiac studies with electrocardiographic gating. Following conventional planar-gated imaging (anterior and left anterior oblique projections), emission computed tomography (ECT), using a rotating gamma camera, was performed.A series of transaxial tomograms of the cardiac chambers was obtained. The left ventricular short-axis plane, long-axis plane, and four-chamber-view plane were then reorganized; each chamber was visualized separately. Compared to gated planar imaging, this technique showed regional asynergy more clearly in patients with myocardial infarction and demonstrated dilatation of the atria and ventricles more accurately in patients with an atrial septal defect and valvular heart diseases. In addition, when a section of the heart is otained at any angle with gated blood pool ECT, three-dimensional assessment of cardiac chambers in motion is more precise; mutual superimposition becomes unnecessary

    Background Depression, anxiety and psychotic disorders have been associated with an increased risk of coronary heart disease (CHD). It is unclear whether this association between mental health and CHD is present across a wider range of mental disorders. Methods and Results Participants were 1,107,524 Swedish men conscripted at mean age 18.3 years. Mental disorders were assessed by psychiatric interview on conscription and data on hospital admissions for mental disorder and CHD were obtained from national registers during 22.6 years of follow-up. Increased risk of incident CHD was evident across a range of mental disorders whether diagnosed at conscription or on later hospital admission. Age-adjusted hazard ratios (95% confidence intervals) according to diagnoses at conscription ranged from 1.30 (1.05, 1.60) (depressive disorders) to 1.92 (1.60, 2.31) (alcohol-related disorders). The equivalent figures according to diagnoses during hospital admission ranged from 1.49 (1.24, 1.80) (schizophrenia) to 2.82 (2.53, 3.13) (other substance use disorders). Associations were little changed by adjustment for parental socioeconomic status, or body mass index, diabetes and blood pressure measured at conscription, but were partially attenuated by adjustment for smoking, alcohol intake, and intelligence measured at conscription, and for education and own socioeconomic position. Conclusions Increased risk of incident CHD is present across a range of mental disorders and is observable when disorders are diagnosed at a young age. PMID:24190959

    The aim of the present study was to examine whether depression and anxiety disorder manifest different autonomic dysregulations using heart-rate variability (HRV) and heart rate (HR) measurements. HRV and HR were recorded both at rest and during task execution (random-number generation) in first-onset drug-naïve patients with major depressive disorder (MDD, n = 14) and generalized anxiety disorder (GAD, n = 11) as well as in healthy controls (n = 41). The patients showed no comorbidity of depression and anxiety disorder. GAD patients did not exhibit panic or phobic symptoms at the time of measurement. Following power spectrum analysis of HR trend, the high- (HF) and low-frequency (LF) components, the sum (LF + HF), and the LF/HF ratio were compared among the groups. In the MDD patients, as previously reported, HF was low and the LF/HF ratio was high during the initial-rest condition, and HF was less reactive to the task. In contrast, GAD patients showed significantly high HF, although autonomic reactivity was not impaired. The results indicate that baseline autonomic activity and its reactivity to behavioral changes are different between MDD and GAD in the early stage of illness. High parasympathetic tone in GAD may reflect responses of the parasympathetic system to anxiety. MDD is accompanied by an autonomic shift toward sympathetic activation and a reduced reactivity to task. © 2016 The Authors.

    The diverse causes of right-sided heart failure (RHF) include, among others, primary cardiomyopathies with right ventricular (RV) involvement, RV ischemia and infarction, volume loading caused by cardiac lesions associated with congenital heart disease and valvular pathologies, and pressure loading resulting from pulmonic stenosis or pulmonary hypertension from a variety of causes, including left-sided heart disease. Progressive RV dysfunction in these disease states is associated with increased morbidity and mortality. The purpose of this scientific statement is to provide guidance on the assessment and management of RHF. The writing group used systematic literature reviews, published translational and clinical studies, clinical practice guidelines, and expert opinion/statements to summarize existing evidence and to identify areas of inadequacy requiring future research. The panel reviewed the most relevant adult medical literature excluding routine laboratory tests using MEDLINE, EMBASE, and Web of Science through September 2017. The document is organized and classified according to the American Heart Association to provide specific suggestions, considerations, or reference to contemporary clinical practice recommendations. Chronic RHF is associated with decreased exercise tolerance, poor functional capacity, decreased cardiac output and progressive end-organ damage (caused by a combination of end-organ venous congestion and underperfusion), and cachexia resulting from poor absorption of nutrients, as well as a systemic proinflammatory state. It is the principal cause of death in patients with pulmonary arterial hypertension. Similarly, acute RHF is associated with hemodynamic instability and is the primary cause of death in patients presenting with massive pulmonary embolism, RV myocardial infarction, and postcardiotomy shock associated with cardiac surgery. Functional assessment of the right side of the heart can be hindered by its complex geometry. Multiple

    Internet gaming disorder (IGD) is characterized by addiction to online gaming and reduced executive control, particularly when individuals are exposed to gaming-related cues. Executive control can be measured as vagally mediated heart rate variability (HRV), which corresponds to variability in the time interval between heart beats. In this study, we investigated whether individuals with IGD have altered HRV while playing online games. We hypothesized that while gaming, individuals with IGD would exhibit phasic suppression of vagally mediated HRV, which would reflect executive control dysfunction during game play. To test this, we measured the changes of HRV when young males with IGD were engaged in real-time online gaming. The changes of HRV were associated with the severity of IGD assessed by self-reports and prefrontal gray matter volume (GMV) calculated by voxel-based morphometry. We included 23 IGD subjects and 18 controls in our analyses. Changes in HRV were not statistically different between IGD subjects and controls. Within the IGD group, however, subjects showed significant decreases in high-frequency (HF) HRV during gaming. Furthermore, the degree of decrease correlated with IGD severity and prefrontal GMV. Importantly, this phasic suppression of HF-HRV in response to gaming did not occur in control subjects. In conclusion, young males with IGD showed an altered HRV response while playing an online game, reflecting their difficulties in executive control over gaming. The dynamics between executive control and reward seeking may be out of balance during game play in IGD.

    Systematic reviews examining associations of depressive disorder with coronary heart disease and stroke produce mixed results. Failure to consider reverse causation and dose-response patterns may have caused inconsistencies in evidence. This prospective cohort study on depressive disorder, coronary heart disease, and stroke analysed reverse causation and dose-response effects using four 5-year and three 10-year observation cycles (total follow up 24 years) based on multiple repeat measures of exposure. Participants in the Whitehall II study (n = 10,036, 31,395 person-observations, age at start 44.4 years) provided up to six repeat measures of depressive symptoms via the 30-item General Health Questionnaire (GHQ-30) and one measure via Center for Epidemiologic Studies Depression Scale (CES-D). The cohort was followed up for major coronary events (coronary death/nonfatal myocardial infarction) and stroke (stroke death/morbidity) through the national mortality register Hospital Episode Statistics, ECG-screening, medical records, and self-report questionnaires. GHQ-30 caseness predicted stroke over 0-5 years (age-, sex- and ethnicity-adjusted HR 1.60, 95% CI 1.1-2.3) but not over 5-10 years (HR 0.94, 95% CI 0.6-1.4). Using the last 5-year observation cycle, cumulative GHQ-30 caseness was associated with incident coronary heart disease in a dose-response manner (1-2 times a case: HR 1.12, 95% CI 0.7-1.7; 3-4 times: HR 2.06, 95% CI 1.2-3.7), and CES-D caseness predicted coronary heart disease (HR 1.81, 95% CI 1.1-3.1). There was evidence of a dose-response effect of depressive symptoms on risk of coronary heart disease. In contrast, prospective associations of depressive symptoms with stroke appeared to arise wholly or partly through reverse causation.

    Background Bacterial endocarditis in dialysis patients is associated with high mortality rates. The literature is limited regarding long-term outcomes of valvular replacement surgery and choice of prosthesis in dialysis patients with bacterial endocarditis. Methods and Results Dialysis patients hospitalized for bacterial endocarditis, 2004-2007, were studied retrospectively using data from the US Renal Data System. Long-term survival of patients undergoing valve replacement surgery with tissue or non-tissue valves was compared using the Kaplan-Meier method. A Cox proportional hazards model was used to identify independent predictors of mortality in patients undergoing valvular replacement surgery. During the study period, 11,156 dialysis patients were hospitalized for bacterial endocarditis and 1267 (11.4%) underwent valvular replacement surgery (tissue valve 44.3%, non-tissue valve 55.7%). In the valve replacement cohort, 60% were men, 50% white, 54% aged 45-64 years, and 36% diabetic. Estimated survival with tissue and non-tissue valves, respectively, at 0.5, 1, 2, and 3 years was 59% and 60%, 48% and 50%, 35% and 37%, and 25% and 30% (log rank P = 0.42). Staphylococcus was the predominant organism (66% of identified organisms). Independent predictors of mortality in patients undergoing valve replacement surgery included older age, diabetes as cause of end-stage renal disease, surgery during index hospitalization, staphylococcus as the causative organism, and dysrhythmias as a comorbid condition. Conclusions Valve replacement surgery is appropriate for well-selected dialysis patients with bacterial endocarditis, but is associated with high mortality rates. Survival does not differ with tissue or non-tissue prosthesis. PMID:23785002

    Full Text Available Since 2000, transcatheter pulmonary valve replacement has steadily advanced. However, the available prosthetic valves are restricted to bioprosthesis which have defects like poor durability. Polymeric heart valve is thought as a promising alternative to bioprosthesis. In this study, we introduced a novel polymeric transcatheter pulmonary valve and evaluated its feasibility and safety in sheep by a hybrid approach.We designed a novel polymeric trileaflet transcatheter pulmonary valve with a balloon-expandable stent, and the valve leaflets were made of 0.1-mm expanded polytetrafluoroethylene (ePTFE coated with phosphorylcholine. We chose glutaraldehyde-treated bovine pericardium valves as control. Pulmonary valve stents were implanted in situ by a hybrid transapical approach in 10 healthy sheep (8 for polymeric valve and 2 for bovine pericardium valve, weighing an average of 22.5±2.0 kg. Angiography and cardiac catheter examination were performed after implantation to assess immediate valvular functionality. After 4-week follow-up, angiography, echocardiography, computed tomography, and cardiac catheter examination were used to assess early valvular function. One randomly selected sheep with polymeric valve was euthanized and the explanted valved stent was analyzed macroscopically and microscopically.Implantation was successful in 9 sheep. Angiography at implantation showed all 9 prosthetic valves demonstrated orthotopic position and normal functionality. All 9 sheep survived at 4-week follow-up. Four-week follow-up revealed no evidence of valve stent dislocation or deformation and normal valvular and cardiac functionality. The cardiac catheter examination showed the peak-peak transvalvular pressure gradient of the polymeric valves was 11.9±5.0 mmHg, while that of two bovine pericardium valves were 11 and 17 mmHg. Gross morphology demonstrated good opening and closure characteristics. No thrombus or calcification was seen macroscopically

    Full Text Available Longevity is increasing and the population of older adults is growing. The biology of aging is conducive to cardiovascular disease (CVD, such that prevalence of coronary artery disease, heart failure, valvular heart disease, arrhythmia and other disorders are increasing as more adults survive into old age.  Furthermore, CVD in older adults is distinctive, with management issues predictably complicated by multimorbidity, polypharmacy, frailty and other complexities of care that increase management risks (e.g., bleeding, falls, and rehospitalization and uncertainty of outcomes.  In this review, state-of-the-art advances in heart failure, acute coronary syndromes, transcatheter aortic valve replacement, atrial fibrillation, amyloidosis, and CVD prevention are discussed.  Conceptual benefits of treatments are considered in relation to the challenges and ambiguities inherent in their application to older patients.

Adults aged 18 years and over with diagnosis codes for AVD or MVD based on International Classification of Diseases (ninth revision diagnosis codes were identified. Subjects were further classified as symptomatic AVD, asymptomatic AVD, symptomatic MVD, and asymptomatic MVD. These classifications were determined with clinical assistance and based in part on data availability in the MEPS.Results: The MEPS database included 148 patients with AVD: 53 patients with symptomatic AVD, 95 patients with asymptomatic AVD, and 1,051 with MVD, including 315 patients with symptomatic MVD and 736 patients with asymptomatic MVD. Symptomatic AVD had the largest incremental effect on annual per patient health-care expenditure: $12,789 for symptomatic AVD, $10,816 for asymptomatic AVD, $5,163 for symptomatic MVD, and $1,755 for asymptomatic MVD. When aggregated to the US population, heart-valve disease accounted for an incremental annual cost of $23.4 billion. The largest aggregate annual costs were incurred by patients with symptomatic MVD ($7

    A comparison of several reported methods for detection and quantitation of left-to-right shunts by radionuclides was performed in 50 children. Count ratio (C2/C1) techniques were compared with the exponential extrapolation and gamma function area ratio techniques. C2/C1 ratios accurately detected shunts and could reliably separate shunts from normals, but there was a high rate of false positives in children with valvular heart disease. The area ratio methods provided more accurate shunt quantitation and a better separation of patients with valvular heart disease than did the C2/C1 ratio. The gamma function method showed a higher correlation with oximetry than the exponential method, but the difference was not statistically significant. For accurate shunt quantitation and a reliable separation of patients with valvular heart disease from those with shunts, area ratio calculations are preferable to the C2/C1 ratio
