    Full Text Available Atrial and ventricular septal defect constitute the most common congenital heart disease.Aim: Τhe aim of the present retrospective study was to record data and factors that affect atrial and ventricular septal defect.Method and material: The sample study included patients of both sexes who were hospitalized with diagnosis atrial and ventricular septal defect in a Cardiac Surgery hospital of Athens. A specially constructed printed form was used for data collection, where were recorded the demographic and personal variables, the pathological, surgical, cardiology and obstetric history, the habits of adults, as well as the personal characteristics of mothers. Analysis of data was performed by descriptive statistical analysis.Results: The sample study consisted of 101 individuals with diagnosis atrial or ventricular Septal Defect, of which 40% were boys and 60% girls. The 70% of the sample study suffered from atrial Septal Defect and the 30% suffered from ventricular Septal Defect. Regarding age, 12% of the sample study was 0-1 years old, 35% was >1 years old, 8% was >12-18 years old and 45% over than 18 years old. Regarding educational status of the adult participants, 9% was of 0-6 years education, 22%>6 -12 years, 13%>12 years. 14% of the adult paticipants smoked, 4% consumed alcohol and 5% smoked in conjunction with alcohol. In terms of the obstetric history of the sample studied, 32% of the cases had normal birth, 4% had a twin birth and 1% had a triplet one. According to the variables related to mothers, the mean age of the mother was 30 years and 3 months, 10% were smokers at pregnancy and 3% used chemical substance and mainly hair color. Also, the results of the present study showed that individuals of 12-18 and >18 years old did not suffer from ventricular Septal Defect, whereas the infants 0-1 years old did not suffer from Atrial Septal Defect. The mean value of age at the admission in intensive care unit was 7 months (12% for the infants

  3. Atrial septal stenting - How I do it?

    Full Text Available A wide atrial communication is important to maintain hemodynamics in certain forms of congenital and acquired heart defects. In comparison to balloon septostomy or blade septostomy, atrial septal stenting provides a controlled, predictable, and long-lasting atrial communication. It often needs a prior Brockenbrough needle septal puncture to obtain a stable stent position. A stent deployed across a previously dilated and stretched oval foramen or tunnel form of oval foramen carries higher risk of embolization. This review provides technical tips to achieve a safe atrial septal stenting. Even though this is a "How to do it article," an initial discussion about the indications for atrial septal stenting is vital as the resultant size of the atrial septal communication should be tailored for each indication.

    Full Text Available Abstract Atrial septal defect closure is now routinely performed using a percutaneous approach under echocardiographic guidance. Centrally located, secundum defects are ideal for device closure but there is considerable morphological variation in size and location of the defects. A small proportion of atrial septal defects may have multiple fenestrations and these are often considered unsuitable for device closure. We report three cases of multiple atrial septal defects successfully closed with two Amplatzer septal occluders.

    Platypnea-orthodeoxia is a peculiar syndrome characterized by a right-to-left shunt, which occurs in the upright position. The diagnosis is made by contrast transesophageal echocardiography, paying attention to include contrast visualization in the orthostatic decubitus. The association of this syndrome with a fenestrated atrial septal aneurysm is rare and probably underlies a peculiar and also rare mechanism of shunting in presence of normal pulmonary pressure. We report of a case of a 58-year-old man with a fenestrated atrial septal aneurysm and platypnea-orthodeoxia syndrome treated by surgical closure of the atrial defect.

    Atrial Septal Defect (ASD) is one of the most frequently congenital heart diseases in adults and it is often asymptomatic until adulthood. We report a case of a 90-year-old woman admitted to hospital with dyspnea and orthopnea insidiously progressing over the preceding 5 years and becoming severe with dyspnea on minimal activities, orthopnea and paroxysmal nocturnal dyspnea, in the last 2 weeks. The transthoracic echocardiogram revealed an atrial septal defect ostium secundum type, with left-to-right shunt, moderate to severe tricuspid insufficiency, severe pulmonary hypertension (72 mmHg) and preserved biventricular function. With diuretic therapy optimization the patient showed symptomatic improvement. This present case represents and unusual and very late presentation of an atrial septal defect ostium secundum type, which is usually diagnosed at the mild adult age. Our patient lived symptom-free for over 80 years.

    Full Text Available We describe an incident of development of acute pulmonary edema after the device closure of a secundum atrial septal defect in a 52-year-old lady, which was treated with inotropes, diuretics and artificial ventilation. Possibility of acute left ventricular dysfunction should be considered after the defect closure in the middle-aged patients as the left ventricular compliance may be reduced due to increased elastic stiffness and diastolic dysfunction. Baseline left atrial pressure may be > 10 mmHg in these patients. Associated risk factors for the left ventricular dysfunction are a large Qp:Qs ratio, systemic hypertension, severe pulmonary hypertension and paroxysmal atrial fibrillation.

    Full Text Available A 3.5-year-old girl underwent transcatheter closure of patent ductus arteriosus in early infancy during which time her secundum atrial septal defect (ASD was left alone. When she came for elective closure of ASD, she was found to have bilaterally blocked femoral veins. The defect was successfully closed with an Amplatzer septal occluder (ASO; St. Jude Medical, Plymouth, MN, USA using a hybrid approach via a sub-mammary mini-thoracotomy incision without using cardiopulmonary bypass. At the end of 1-year follow-up, the child is asymptomatic with device in a stable position without any residual shunt.

    Full Text Available Echocardiography provides a useful tool in the diagnosis of many congenital heart diseases, including atrial septal defects, and aids in further delineating treatment options. Although two-dimensional echocardiography has been the standard of care in this regard, technological advancements have made three-dimensional echocardiography possible, and the images obtained in this new imaging modality are able to accurately portray the morphology, location, dimensions, and dynamic changes of defects and many other heart structures during the cardiac cycle.

    2003-01-01

    Full Text Available OBJECTIVE: To evaluate the initial clinical experience with the Helex septal occluder for percutaneous closure of atrial septal defects. METHODS: Ten patients underwent the procedure, 7 patients with ostium secundum atrial septal defects (ASD with hemodynamic repercussions and 3 patients with pervious foramen ovale (PFO and a history of stroke. Mean age was 33.8 years and mean weight was 55.4 kg. Mean diameter by transesophageal echocardiography and mean stretched ASD diameter were 11.33 ± 3.3mm, and 15.2 ± 3.8mm, respectively. The Qp/Qs ratio was 1.9 ± 0.3 in patients with ASD. RESULTS: Eleven occluders were placed because a patient with 2 holes needed 2 devices. It was necessary to retrieve and replace 4 devices in 3 patients. We observed immediate residual shunt (< 2mm in 4 patients with ASD, and in those with patent foramen ovale total occlusion of the defect occurred. No complications were noted, and all patients were discharged on the following day. After 1 month, 2 patients with ASD experienced trivial residual shunts (1mm. In 1 patient, we observed mild prolapse in the proximal disk in the right atrium, without consequences. CONCLUSION: The Helex septal occluder was safe and effective for occluding small to moderate atrial septal defects. Because the implantation technique is demanding, it requires specific training of the operator. Even so, small technical failures may occur in the beginning of the learning curve, but they do not involve patient safety.

    Objectives To investigate the causes, theraputic and preventive methods of complications associated with transcatheter occlusion of atrial septal defect (ASD) using the Amplatzer septal occluder (ASO) in children. Methods 289 cases underwent transcatheter closure of ASD with ASO. Complications occurred in 9 cases. The complications in procedure included systemic circulatory systemic air embolism in 2, pulmonary air embolism in 1, pericardial tamponade in 1, ASO malposition requiring emergency surgical removal in 1, transient atrial extrasystoles in 1 and sizing balloon rupture in 1 case. 2 cases with postoperative complications were found in the follow-up studies. These included perforation of mitral valve and ASO partially dislodged. In this study, 5children with intraoperative complication received emergency therapy including surgical intervention, and others needed only follow-up, as the complications were transient or asymptomatic. Results There were no children death in this study. The 5 cases who received treatment were completely healing, and the others with intra - procedure complications were also had no sequela existed. Cases with mitral valve and ASO partially dislodged were still in follow-up studies, as the 2 patients having no symptoms. Conclutions Air embolism were occurred easily in atrial septal defect cases who received ASO therapy. Complications mainly caused by inappropriate operative procedure and some complications needed emergency treatments. Follow-up studies were important to cases with transcatheter occlusion therapy.

    Objective To evaluate the safety and efficacy of the Amplatzer septal occluder for transcatheter closure in patients with secundum atrial septal defect (ASD Ⅱ). Methods Patients with clinically confirmed ASD Ⅱ were recommended for transcatheter closure of ASD Ⅱ. Results 30 ASD Ⅱ patients (20 females) underwent transcatheter closure at a median age of 18.4 years (5-55 years). Both the stretched diameters of ASDs and the sizes of the devices were from 18 to 34?mm (25±7?mm). The successful placement rate was 100%. The rest shunt documented by color Doppler, was immediately after implantation in 40% of patients, in 9.9% after 24 hours, and in 3.3% trace at 3 months. No serious complications were observed. There was improvement in symptoms and in cardiac size. Septal motion abnormalities normalized in all patients after 3 months follow-up. Conclusion The Amplatzer septal occluder is a safe and effective device for transcatheter closure of ASD Ⅱ. Long-term follow-up is still required before widespread clinical use can be recommended.

  1. Percutaneous closure of atrial septal defects leads to normalisation of atrial and ventricular volumes

    2008-12-01

    Full Text Available Abstract Background Percutaneous closure of atrial septal defects (ASDs should potentially reduce right heart volumes by removing left-to-right shunting. Due to ventricular interdependence, this may be associated with impaired left ventricular filling and potentially function. Furthermore, atrial changes post-ASD closure have been poorly understood and may be important for understanding risk of atrial arrhythmia post-ASD closure. Cardiovascular magnetic resonance (CMR is an accurate and reproducible imaging modality for the assessment of cardiac function and volumes. We assessed cardiac volumes pre- and post-percutaneous ASD closure using CMR. Methods Consecutive patients (n = 23 underwent CMR pre- and 6 months post-ASD closure. Steady state free precession cine CMR was performed using contiguous slices in both short and long axis views through the ASD. Data was collected for assessment of left and right atrial, ventricular end diastolic volumes (EDV and end systolic volumes (ESV. Data is presented as mean ± SD, volumes as mL, and paired t-testing performed between groups. Statistical significance was taken as p Results There was a significant reduction in right ventricular volumes at 6 months post-ASD closure (RVEDV: 208.7 ± 76.7 vs. 140.6 ± 60.4 mL, p Conclusion ASD closure leads to normalisation of ventricular volumes and also a reduction in right atrial volume. Further follow-up is required to assess how this predicts outcomes such as risk of atrial arrhythmias after such procedures.

    Sinus node (SN) and atrioventricular node (AVN) function were evaluated in 49 patients with secundum type atrial septal defect (ASD). Automaticity and conduction system function were assessed by intracardiac recording of the AH and HV intervals at rest, corrected SN recovery time, sinoatrial conduction time, AVN refractory period and the ability of the AVN to conduct rapidly paced atrial beats to the ventricles. Electrophysiologic abnormalities were found in 41% of the 34 patients who were studied before surgery. However, no preoperative abnormalities were present in children younger than 2.5 years. If only children older than 2.5 years were analyzed, the incidence of conduction abnormalities was similar for the patients studied before operation (62%) and those studied after operation (71%). The size and ejection fractions of the right and left ventricles, the magnitude of shunt flow and the size of the ASD did not differ between the patients with and those without electrophysiologic abnormalities. AVN dysfunction was present in 40% of the patients who were studied after surgical repair. While this frequency was more than twice the preoperative incidence of AVN dysfunction, it was not statistically significant. The data suggest that patient age is the major factor that influences the presence of conduction system dysfunction in patients with ASD.

    Bacterial endocarditis following atrial septal defect closure using Amplatzer device in a child is extremely rare. We report a 10-year-old girl who developed late bacterial endocarditis, 6 years after placement of an Amplatzer atrial septal occluder device. Successful explantation of the device and repair of the resultant septal defect was carried out using a homograft patch. The rare occurrence of this entity prompted us to highlight the importance of a closed long-term follow up, review the management and explore preventive strategies for similar patients who have multiple co-morbidities and a cardiac device. A high index of suspicion is warranted particularly in pediatric patients.

  5. Recurrence of atrial septal defect in three generations

    Full Text Available Beginning with a patient presenting with an atrial septal defect (ASD of the secundum type, the genealogy was identified in four affected individuals who belonged to three successive generations of the same family. The defects were visually confirmed in all individuals and were found to be anatomically similar. No other congenital malformations were present in these individuals. The genealogy was identified in 1972, when ASD recurred in two generations, and it was concluded that the mechanism of transmission was autosomal recessive. The fifth individual, identified 21 years later, and having an anomaly identical to that of the others, was the child of a couple who had no consaguinity and whose mother was a member of the previously studied genealogy. Considering the absence of phenotype in the parents and the rarity of the ASD gene in the general population, the occurrence of the uniparental disomy for this family nucleus, and the same autosomal recessive mechanism of transmission by this affected individual is possible. This study reports the familial occurrence of ASD by genetic mechanisms of transmission, emphasizing the necessity for genetic-clinical studies in members of the familial nucleus in order to detect new carriers, who usually are asymptomatic, thereby allowing for early and adequate treatment of individuals who may be affected.

Percutaneous ASD closure has established procedural safety through operator experience and improved device structure and deliverability. There have also been advances in diagnostic capabilities. Devices have evolved from large bulky meshes to repositionable, minimal residual mesh content that easily endothelializes and conforms well to surrounding structures. Biodegradable technology has been introduced and will be closely watched as a future option. The evolution of ASD closure device usage in the last four decades incorporates development that minimizes a wide range of serious side effects that have been reported over the years. Complications reported in the literature include thrombus formation, air embolization, device embolization, erosions, residual shunts, and nickel hypersensitivity. Modern devices have intermediate to long term data with outcomes that have been favorable. Devices are available in multiple sizes with improved delivery mechanisms to recapture, reposition, and safely close simple and complex ASDs amenable to percutaneous closure. In this review, commonly used devices and deployment procedures are discussed together with a look at devices that show promise for the future.

    Sinus venosus atrial septal defect is a rare congenital, interatrial communication defect at the junction of the right atrium and the vena cava. It accounts for 5–10% of cases of all atrial septal defects. Due to the rare prevalence and anatomical complexity, diagnosing sinus venous atrial septal defects poses clinical challenges which may delay diagnosis and treatment. Advanced cardiac imaging studies are useful tools to diagnose this clinical entity and to delineate the anatomy and any associated communications. Surgical correction of the anomaly is the primary treatment. We discuss a 43-year-old Hispanic female patient who presented with dyspnea and hypoxia following a laparoscopic myomectomy. She had been diagnosed with peripartum cardiomyopathy nine years ago at another hospital. Transesophageal echocardiography and computed tomographic angiography of the chest confirmed a diagnosis of sinus venosus atrial septal defect. She was also found to have pulmonary arterial hypertension and Eisenmenger syndrome. During a hemodynamic study, she responded to vasodilator and she was treated with Ambrisentan and Tadalafil. After six months, her symptoms improved and her pulmonary arterial hypertension decreased. We also observed progressive reversal of the right-to-left shunt. This case illustrates the potential benefit of vasodilator therapy in reversing Eisenmenger physiology, which may lead to surgical repair of the atrial septal defect as the primary treatment.

    Hypertrophic cardiomyopathy (HCM) is a cardiac disease associated with a high incidence of atrial fibrillation (AF). Recent studies have suggested that interventricular septum thickness may influence the risk stratification of patients with AF. We evaluated the effects of septal hypertrophy on morbidity and mortality in patients with HCM. Patients were followed for a median of 6.1 years and were divided into two groups according to the extent of septal hypertrophy. A total of 1,360 HCM patients were enrolled: 482 (33%) apical or apicoseptal, 415 (28%) asymmetric septal, 388 (27%) basal septal, 38 (2.6%) concentric, and 37 (2.5%) diffuse and mixed type. Ninety-two all-cause deaths and 21 cardiac deaths occurred. The total event rates were significantly higher for patients with HCM with more extensive septal hypertrophy (group A) compared to those with HCM ± focal septal hypertrophy (group B), regardless of type (p<0.001). Arrhythmias occurred in 502 patients, with a significantly higher incidence in group A than in group B (p<0.001). Among patients with arrhythmias, the incidence of AF was significantly higher in group A than group B (p<0.001). In univariate Cox analysis, a greater extent of septal hypertrophy (p<0.001), E/E´ ratio (p = 0.011), and mitral regurgitation grade (p = 0.003) were significantly associated with developing AF. In multivariate Cox analyses, a greater extent of septal hypertrophy [odds ratio (OR) 5.44 (2.29-12.92), p<0.001] in patients with HCM was significantly associated with developing AF. In conclusion, a greater extent of septal hypertrophy is an independent predictor of progression to AF in patients with HCM.

    Full Text Available We report prolonged desaturation in a child with Down syndrome (DS and atrial septal defect due to undiagnosed interstitial lung disease. An 18-month-old child with DS was scheduled for bilateral lens aspiration for cataract. The child had atrial septal defect and hypothyroidism. He also had delayed milestones and hypotonia with episodes of recurrent respiratory tract infection necessitating repeated hospitalization. Preoperative evaluation was unremarkable. General anaesthesia and controlled ventilation using proseal laryngeal mask airway was instituted. He had uneventful intraoperative period. In the postoperative period, the child had desaturation 1 hour after surgery on discontinuation of oxygen supplementation by face mask, which improved with oxygen therapy. Supplemental oxygen via face mask was continued and weaned off over several days. On further evaluation, the child was diagnosed as having interstitial lung disease. He improved and discharged from the hospital 15 days after the surgery with room air saturation of 90%.

    Full Text Available To date seven different types of atrial septal defects (ASD have been described and they include septum primum, septum secundum, superior vena cava, inferior vena cava, coronary sinus and patent foramen ovale types of ASD. One feature in common among these ASD’s is that they all present with a hole that may allow communication between the left and right atria. The current observation reports what appears to be a new type of ASD that is characterized by the presence of an oblique septal canal that opens into the right and left atria. The right atrial opening was D-shaped and measured about 0.9 cm wide and the left atrial opening was crescent-shaped and measuring about 0.5 cm wide. In addition to this the left atrial opening was associated with five luminal bands; the last three bands lies on the roof of the oblique septal canal. The action of pulling the first luminal band resulted into closure of the left atrial opening an indication that the bands prevented blood coming from the lungs from entering into the right atrium. The presence of oblique septal canal and luminal bands has not been reported in relation to the ASD’s. Continued documentation of such anomalies remains clinically important particularly in African settings where unexplained illnesses are easily attributed to endemic diseases.

    Arrhythmogenic right ventricular cardiomyopathy is characterised by progressive, fibrofatty replacement of myocardium, and ventricular arrhythmias, and its prognosis is usually poor. Arrhythmogenic right ventricular cardiomyopathy associated with atrial septal defect is very rare, and this combination may make the diagnosis, treatment, and prognosis difficult. We present a case of a patient with this association who underwent interventional treatment with a septal defect occluder. Transcatheter closure of atrial septal defect in a patient with arrhythmogenic right ventricular cardiomyopathy is hitherto unreported. During a 3-year follow-up he remained relatively stable. We also review the cases reported in the medical literature describing this uncommon association between arrhythmogenic right ventricular cardiomyopathy and atrial septal defect or patent foramen ovale.

    A 56-year-old woman was diagnosed as atrial septal defect (ASD) with pulmonary hypertension; pulmonary blood flow/systemic blood flow (Qp/Qs) of 2.3, pulmonary artery pressure (PAP) of 71/23(39) mmHg and diastolic dysfunction of left ventricle. PAP was improved after medical therapy; therefore, transcatheter ASD closure was performed. Seven days later, left-sided heart failure occurred, however, the improvement of Qp/Qs (1.7) and PAP of 51/21(32) was confirmed. Diuretic therapy was introduced which led to further decrease of PAP 40/12(25) and Qp/Qs (1.1). Because of gradual decrease of Qp/Qs, this patient appeared to be protected from acute pulmonary edema.

    Full Text Available Background: With a prevalence of almost 7% of all congenital heart diseases, atrial septal defect (ASD is a common condition. Patent foramen ovale (PFO is also a congenital heart disease which is frequently sustained into adulthood. Objectives: To study the feasibility of closure of ASD and PFU by Starway septal occluder device and the incidence of its inherent complications and procedural failure in 62 patients referred to our center. Methods: Starway septal occluder device was used for closure of ASD and PFO in 62 patients. After left and right heart catheterization, transesophageal echocardiography-guided closure was done for the patients with immediate recording of the results. Patients were followed for 6 months by transesophageal echocardiography for observing short- and mid-term complications. Results: The 62 studied patients were categorized into 2 groups. Group 1 included 31 patients (64% females with ASD (mean±SD age: 26.7±7.6 years. Group 2 consisted of 31 patients (35.6% females with PFO (mean±SD age: 53.5±12.4 years. Size of the right ventricle (RV annulus was significantly (P=0.005 decreased after the intervention in the ASD group. Overall 5 (8% patients developed post-intervention complications (transient ischemic attack, leg edema, and residual shunt and procedural failure—4 (13% in ASD group and 1 (3% in PFO group. None of the patients developed device-related thrombosis, significant arrhythmia, aortic regurgitation and pericardial effusion after intervention. Conclusion: Starway occluder device is effective and safe with very low short- and mid-term complication rates.

    Full Text Available Abstract Background Many adult patients with secundum-type atrial septal defects (ASDs are able to have these defects fixed percutaneously. Traditionally, this has involved an assessment of ASD size, geometry and atrial septal margins by transoesophageal echocardiography (TOE prior to percutaneous closure. This is a semi-invasive technique, and all of the information obtained could potentially be obtained by non-invasive cardiovascular magnetic resonance (CMR. We compared the assessment of ASDs in consecutive patients being considered for percutaneous ASD closure using CMR and TOE. Methods Consecutive patients with ASDs diagnosed on transthoracic echocardiography (TTE were invited to undergo both CMR and TOE. Assessment of atrial septal margins, maximal and minimal defect dimensions was performed with both techniques. Analyses between CMR and TOE were made using simple linear regression and Bland Altman Analyses. Results Total CMR scan time was 20 minutes, and comparable to the TOE examination time. A total of 20 patients (M:F = 5:15, mean age 42.8 years ± 15.7 were included in the analyses. There was an excellent agreement between CMR and TOE for estimation of maximum defect size (R = 0.87. The anterior inferior, anterior superior and posterior inferior margins could be assessed in all patients with CMR. The posterior superior margin could not be assessed in only one patient. Furthermore, in 1 patient in whom TOE was unable to be performed, CMR was used to successfully direct percutaneous ASD closure. Conclusions CMR agrees with TOE assessment of ASDs in the work-up for percutaneous closure. Potentially CMR could be used instead of TOE for this purpose.

    Background Whether the low molecular weight heparin microcapsule coated occluder is helpful to endothelialization in atrial-septal defect models is uncertain. This study aimed to investigate the best conditions for low molecular weight heparin coated Nil-I alloy occluder and provide the evidence of the efficacy and safety of atrial-septal defect occluders in vivo.Methods Low molecular weight heparin microcapsules were investigated using gelatin as microcapsule material. The prepared low molecular weight heparin gelatin particles were subjected to nickel and titanium alloy occluder coating by sodium hyaluronate. A dog model of atrial septal defects was established after treatment with low molecular weight heparin microcapsule coated occluder (n=4) and uncoated occluder (n=4). Endotheliocytes and fibroblastic cells in occluders were observed. And the rate of endothelialization was detected.Results When the concentration of gelatin was 1%, the diameters of particles were mostly about 100 pm, and the particle size was uniform. The envelope efficiency of low molecular weight heparin microcapsule was about 80%. The endothelialization of occluder in the model was more obvious in the coated group than in the uncoated group (P <0.0001).Conclusions Low molecular weight heparin can be prepared into microcapsules with their particle size in nanometric grade. The antithrombotic properties are kept in the nickel and titanium alloy occluder successfully coated with sodium hyaluronate. The endothelialization after the interventional occlusion in the coated group is obvious, indicating that low molecular weight heparin is helpful to the growth of endothelial cells in the occlude and the healing after the interventional occlusion.

    Full Text Available Introduction: We aimed to develop a classification method to discriminate ventricular septal defect and atrial septal defect by using severalhemodynamic parameters.Patients and Methods: Forty three patients (30 atrial septal defect, 13 ventricular septal defect; 26 female, 17 male with documentedhemodynamic parameters via cardiac catheterization are included to study. Such parameters as blood pressure values of different areas,gender, age and Qp/Qs ratios are used for classification. Parameters, we used in classification are determined by divergence analysismethod. Those parameters are; i pulmonary artery diastolic pressure, ii Qp/Qs ratio, iii right atrium pressure, iv age, v pulmonary arterysystolic pressure, vi left ventricular sistolic pressure, vii aorta mean pressure, viii left ventricular diastolic pressure, ix aorta diastolicpressure, x aorta systolic pressure. Those parameters detected from our study population, are uploaded to multi-layered artificial neuralnetwork and the network was trained by genetic algorithm.Results: Trained cluster consists of 14 factors (7 atrial septal defect and 7 ventricular septal defect. Overall success ratio is 79.2%, andwith a proper instruction of artificial neural network this ratio increases up to 89%.Conclusion: Parameters, belonging to artificial neural network, which are needed to be detected by the investigator in classical methods,can easily be detected with the help of genetic algorithms. During the instruction of artificial neural network by genetic algorithms, boththe topology of network and factors of network can be determined. During the test stage, elements, not included in instruction cluster, areassumed as in test cluster, and as a result of this study, we observed that multi-layered artificial neural network can be instructed properly,and neural network is a successful method for aimed classification.

    Unilateral pulmonary artery agenesis is a rare congenital anomaly caused by a backward displacement of the conical artery of the truncus arteriosus. It is commonly associated with additional cardiovascular abnormalities. A 7-year-old girl was admitted to our clinic with the complaint of shortness of breath upon exertion. Chest radiography revealed a hypoplastic right lung. Absence of the right pulmonary artery with atrial septal defect and pulmonary hypertension was demonstrated by echocardiography, computed tomography, and cardiac catheterization. Bosentan is effectively used to treat pulmonary arterial hypertension.

    A 1-month-old Hispanic female was referred to the cardiology service. During physical examination, a systolic ejection murmur at the pulmonic area was auscultated. The echocardiography evaluation of the pulmonary valve demonstrated a quadricuspid pulmonary valve (QPV) with slightly thickened leaflets, associated atrial septal defects and mild pulmonary stenosis. QPV is a rare congenital anomaly variant that can remain asymptomatic with few or non-hemodynamic alterations. Associations with structural or functional alterations have been reported. This is the first case of QPV that was diagnosed in a Hispanic newborn. PMID:26138189

    2017-01-01

    Localized ventricular septal hypertrophy, also known as idiopathic hypertrophic subaortic stenosis or idiopathic hypertrophic subaortic septal obstruction (IHSS), can create severe ventricular outflow obstruction. This often results in a high sub-aortic pressure gradient with potentially lethal symptoms. In 1960, Braunwald described the hemodynamic characteristics of IHSS, and thereafter, Morrow developed a trans-aortic approach to resect a large part of the ventricular septum, enlarging the outflow tract. The Morrow operation has remained the gold standard for surgically treating this pathology. However, in patients with a small aortic annulus, a severely hypertrophied septum, and a long anterior mitral leaflet, the trans-aortic approach may be more difficult, resulting in an inadequate resection and/or systolic anterior leaflet motion. The latter usually increases the obstruction and can cause mitral regurgitation. Herein, we describe a minimally invasive trans-left atrial robotic approach to treat IHSS. First, the anterior mitral leaflet is incised radially to reveal the aortic outflow tract and ventricular septum, which are located posteriorly. Thereafter, a deep “block” of septum is excised, beginning at the right valve cusp nadir and continued counterclockwise toward the left fibrous trigone. This excision is extended to the anterior papillary muscle base, where any septal connections must be divided. Subsequently, the anterior leaflet is re-suspended and the repair is completed with a flexible annuloplasty band. If necessary, the anterior leaflet can be augmented with a pericardial patch. The “wristed” robotic instruments and magnified 3-D vision definitely facilitate an adequate septal resection and anterior papillary muscle mobilization. Moreover, it is possible that this fine control helps to reduce complications, such as heart block or a ventricular septal defect. PMID:28203542

    Full Text Available Background: The transcatheter closure of the atrial septal defect (ASD has become an alternative technique to surgical procedures. The aim of this study was to assess the immediate, short, and intermediate-term results of the transcatheter closure of the secundum ASD with the Amplatzer Septal Occluder (ASO in adult Iranian patients.Methods: Between December 2004 and July 2008, the transcatheter closure of the ASD using the ASO was attempted in 58consecutive, adult patients. The mean age of the patients was 37.1 ± 12.7 years (range = 19 - 75 years.All the procedures were performed under local anesthesia with transthoracic or transesophageal echocardiography and fluoroscopic guidance. The stretched diameter of the ASD was determined with a balloon sizing catheter, and device selection was based on and matched to the stretched diameter of the septal defect.Transthoracic echocardiography was performed immediately after the release of the device and before discharge.Further follow-up at one month, six months, and yearly thereafter included physical examination, electrocardiography, andtransthoracic echocardiography.Results: The mean ASD diameter, as measured by esophageal echocardiography, was 24.8 ± 5.4 mm (range = 13 - 34 mm.The mean stretched diameter, as measured by the balloon catheter, was 27.1 ± 6.4 mm (range = 12.5 - 39 mm. Deploymentof the ASO was successful in 52 (89.6% patients and failed in 6 (10.4%. Four patients experienced severe complications,1 had tamponade requiring drainage, 2 had device embolization to the left atrium and right ventricular outflow tract, and 1 had late wire fracture (surgical removal and repair of the ASD. The position of two large devices (34 mm and 36 mm was considered unsuitable and unstable after implantation and resulted in the removal of these devices.Minor complications included transient complete atrioventricular block in 1 patient, paroxysmal supra tachycardia in 3 patients, atrial flutter in 1 patient

    Cyanosis in atrial septal defect typically occurs when pulmonary hypertension develops. Platypnea-orthodeoxya is an uncommon syndrome, still under debate, characterized by breathlessness and arterial oxygen desaturation exacerbated in the upright position. An interatrial communication is a common finding in this syndrome, but the absence of a right to left pressure gradient complicates the physiopathological picture. To explain the right to left shunt, it is generally advocated a concomitant condition that alternates the sterical relationship between inferior vena cava orifice and the atrial septal defect. A case of a 58-year-old male with platypnea-orthodeoxya syndrome related to a fenestrated redundant interatrial septum without any additional pathologic condition is reported. Possibly, this isolated anatomical abnormality could lead to a right to left shunt in the absence of other coexisting predisposing factors. It is reasonable to hypothesize the septum secundum bulging like a 'spinnaker' into the right atrium, so that it deviates the inferior vena cava venous blood towards the left atrium. Echocardiographic evaluation is mandatory to achieve a correct diagnosis and to decide the therapeutic strategy.

    Full Text Available The aim of this study was to perform a budget impact analysis on the adoption of percutaneous occlusion of ostium secundum atrial septal defects in the Brazilian Unified National Health System. Costs were collected using micro-costing technique from medical records for each treatment technique (conventional surgery versus percutaneous septal occluder at a public federal hospital specialized in high-complexity cardiology. The analysis showed that expenditures associated with percutaneous occlusion were lower than with conventional surgery, and sensitivity analysis confirmed the cost reduction in several scenarios, showing a significant budget impact with a 30% adoption rate for the percutaneous occluder (savings of approximately 1.5 million dollars per year. The study indicates that the adoption of the percutaneous septal occluder would mean cost savings of approximately 3.5 million dollars for the Brazilian public health system.

  18. Disturbances in atrial rhythm and conduction following the surgical creation of an atrial septal defect by the Blalock-Hanlon technique.

    Disturbances in atrial conduction or rhythm, or both, were found in 16 of 27 patients undergoing the surgical creation of an atrial septal defect by the Blalock-Hanlon technique. These included P-wave aberrations of intra-atrial block and ectopic atrial rhythm, A-V rhythm, A-V dissociation, sinus bradycardia, atrial flutter, escape-capture bigeminy, and atrial premature beats. Some of these were transient and occurred within 2 weeks after surgery. It seems likely that tissue trauma engendered by the clamp and resection of the atrial septum with possible injury to the internodal conducting pathways may be the genesis of these early postoperative disturbances. Of the eight cases with transient disturbances, six occurred in this period. Later changes, such as intra-atrial block, sinus bradycardia, and atrial flutter, may be attributed to changes in atrial size secondary to the postoperative pathophysiology. Digitalis intoxication and congestive heart failure cannot be excluded as contributory factors in either the early or the late disturbances. It was not possible to correlate the incidence and nature of these disturbances with morbidity and mortality. In such severely ill, cyanotic infants, irregularities, however slight, may have altered cardiac function significantly and contributed to their deaths.

    Background and Purpose: An association between atrial septal aneurysm and embolic events has been suggested. Atrial septal aneurysm has been shown to be associated with patent foramen ovale and,.in some reports, with mitral valve prolapse. These two latter cardiac disorder; have been identified as potential risk factors for ischemic stroke. The aim of this prospective study was to assess the role of atrial septal aneurysm as an independent risk factor for stroke, especially for cryptogenic stroke. Methods: We studied the prevalence of atrial septal aneurysm, patent foramen ovale, and mitral valve prolapse in 100 consecutive patients patent foramen ovale relied on transesophageal echocardiography with a contrast study and that of mitral valve prolapse, on two-dimensional transthoracic echocardiography. Results: Stepwise logistic regression analysis showed that atrial septal aneurysm (odds ratio, 4.3; 95% confidence interval, 1.3 to 14.6; P=.01) and patent foramen ovale (odds ratio, 3.9; 95% confidence interval, 1.5 to 10; P=.003) but not mitral valve prolapse were significantly associated with the diagnosis of cryptogenic stroke. The stroke odds of a patient with both atrial septal aneurysm and patent foramen ovale were 33.3 times (95% confidence interval, 4.1 to 270) the stroke odds of a patient with neither of these cardiac disorders. For a patient with atrial septal aneurysm of >lo-mm excursion, the stroke odds were approximately 8 times the stroke odds of a patient with atrial septal aneurysm of patent foramen ovale are both significantly associated with cryptogenic stroke and that their association has a marked synergistic effect. Atrial septal aneurysms of >lo-mm excursion are associated with a higher risk of stroke. (Stroke. 1993;24:1865-1873.)

    Atrial septal aneurysm remains a rare congenital cardiac malformation. In the neonatal age group it can occur as an isolated cardiac malformation or in association with complex hypoplastic cardiac malformations of the right and left heart. In the adult population most aneurysms have been described in association with stroke. Baby H.N delivered on 10/05/2008 by C/S, was cyanosed at birth with systemic desaturation. Chest X-ray showed oligaemic lung fields while two dimensional echocardiograms showed tricuspid atresia with hypoplastic right ventricle, large secundum atrial septal defect, and highly mobile gigantic aneurysms of the atrial septum obstructing the inflow of the mitral valve and entering the left ventricle in diastole. Surgical intervention was not possible and child died on second day.

    Pulmonary agenesis, a rare congenital condition, is incompatible with life when present bilateral, while unilateral agenesis is usually detected in infancy or early childhood. Rare asymptomatic patients may reach adulthood undiagnosed, with signs mimicking common conditions presenting as radiopaque hemithorax with ipsilateral mediastinal shift. Here, we describe a case of a young lady, with history of consanguinity, who presented with complaints, suggestive of lower respiratory tract infection, and was investigated and diagnosed to be a case of right-side pulmonary agenesis with large ostium secondum atrial septal defect. Our present case emphasizes the importance of presence of pulmonary agenesis with cardiac congenital anomaly, remaining asymptomatic until adulthood, particularly in patients born of parents with consanguineous marriages.

    Full Text Available Introduction. Transcatheter atrial septal defect (ASD closure is considered to be a gold standard for patients with the suitable anatomy as compared to cardiac surgery. Reocurrence of ASD after surgical closure is a very rare late complication which can be successfully managed with transcatheter procedure. Case report. We reported a female patient with Noonan syndrome who presented with hemodinamically significant ASD 37 years after the corrective cardiac surgery. Due to numerous comorbidities which included severe kyphoscoliosis, pectus excavatum and multiple surgeries we decided to perform transcatheter closure of ASD. The procedure itself was very challenging due to the patient’s short stature and heart’s orientation in the chest, but was performed successfully. The subsequent follow-up was uneventful and the patient reported improvement in the symptoms. Conclusion. Transcatheter closure of ASD in a patient with Noonan syndrome with the history of surgically corrected ASD can be performed successfully, despite challenging chest anatomy.

    Atrial septal defects (ASDs) are a common congenital abnormality, and operative repair is a routine, safe procedure. Diversion of the inferior vena cava (IVC) into the left atrium is an unusual complication following ASD closure. We report a case that illustrates the problem created by this right-to-left shunt. A middle-aged woman underwent ASD repair. She developed hypoxemia postoperatively. A transthoracic echocardiogram confirmed a right-to-left shunt, found only with agitated saline injected into the femoral vein, not into the basilic vein. Surgical reexploration revealed a residual ASD diverting IVC flow into the left atrium, which was repaired with a pericardial patch. Echocardiography with agitated saline injected from the femoral vein is an easy method to diagnose this uncommon complication.

    Objective:To study the clinical value of right heart function assessment with real-time three-dimensional echocardiography before and after atrial septal defect surgery. Methods:Patients with atrial septal defect who received transcatheter closure in our hospital were selected for study and divided into non-pulmonary hypertension group and pulmonary hypertension group according to pulmonary artery systolic pressure (PASP), real-time three-dimensional echocardiography was conducted before and after operation, and right ventricular end-diastolic volume (RVEDV), right ventricular end-systolic volume (RVESV), right ventricular stroke volume (RVSV), right ventricular ejection fraction (RVEF) and right ventricular cardiac output (RVCO) were calculated;serum was collected, and brain natriuretic peptide (BNP), atrial natriuretic peptide (ANP), angiotensin I (AngI), angiotensin II (AngII) and endothelin (ET) contents were detected. Results:After operation, RVEDV, RVESV, RVSV, RVEF and RVCO as well as serum BNP, ANP, AngI, AngII and ET contents of both groups were lower than those before treatment;RVEDV, RVESV, RVSV, RVEF and RVCO were positively correlated with contents of BNP, ANP, AngI, AngII and ET. Conclusions:Using real-time three-dimensional echocardiography before and after atrial septal defect surgery can accurately assess right heart function, and it has good correlation with right heart volume load and pulmonary circulation blood flow.

    Echocardiograms were performed in 80 infants and children with isolated ventricular septal defect (VSD) who underwent cardiac catheterization. The pulmonary-to-systemic flow ratio (Qp/Qs) was correlated with the echocardiographic left atrial-to-aortic root diameter ratio (LA/Ao), and a relatively poor correlation (r = 0.62) was found. The end-systolic diameters of the left atrium and aorta at the level of the aortic root, obtained from lateral cineangiograms of 55 of the 80 patients, were compared with the corresponding echocardiographic dimensions. To assess the possible effect of transducer beam angulation upon the echocardiographic determinations, the angiographic measurements were made at 0 degrees position (perpendicular to the frontal plane) and at angles of 5 degrees, 10 degrees, 15 degrees and 20 degrees from zero, using the aortic root center as the point of intersection. The echocardiographic and angiographic aortic root measurements were comparable (r = 0.95), and the angiographically derived aortic diameter did not vary with different angle projections. However, the left atrial angiographic dimensions were significantly influenced by the angle of projection. We conclude that the echocardiographic LA/Ao ratio cannot reliably estimate the severity of the shunt flow in VSD.

    We report the management of a patient with secundum atrial septal defect (ASD)and severe pulmonary hypertension.A 65-year-old male with recently diagnosed atrial serital defect was referred to our centre for decompensated right heart failure with rest and exercise induced dispnea and severe pulmonary hypertension.Right heart catheterization confirmed a mean pulmonary pressure of about 55 mmHg and a Qp/Qs of 2.7.An occlusion test with a compliant large balloon demonstrated partial fall of pulmonary arterial pressure.The implantation of a home-made fenestrated Amplatzer ASD Occluder (ASO) was planned in order to decrease lefttoright shunt and promote further decrease of pulmonary arterial pressure in the long-term.Thus,by means of mechanical intracardiac echocardiography study with a 9F 9 MHz Ultralce catheter(Boston Scientific Corp.),we selected a 34 mm ASO for implantation.Four millimeter fenestration was made inflating a 4 ntm non-compliant coronary balloon throughout the waist of the ASO,which was successfully implanted under intracardiac echocardiography.After six months,a decrease of pulmonary arterial pressure to 24 mmHg and full compensated right heart failure was observed on transthoracic echocardiography and clinical examination.This case suggests that transcatheter closure with home-made fenestrated ASD in elderly patients with severe pulmonary hypertension is feasible.

    Full Text Available Objective: The aim of this study is to determine safety and feasibility of conscious sedation using dexmedetomidine for transcatheter atrial septal defect (ASD device closure. Material and Methods: A retrospective institutional review of transcatheter ASD device closure without endotracheal intubation over 18 months. The protocol included topical oropharyngeal anesthesia using lignocaine followed by dexmedetomidine bolus 1 μg/kg intravenously over 10 min and maintenance dose 0.2-0.7 μg/kg/h. Ramsay sedation score 2-3 was maintained. Patients were analyzed regarding demographic profile, device size, procedure time, anesthesia time, recovery time, hospital stay, and any hemodynamic or procedural complications. Results: A total of 43 patients with mean age 31.56 ± 13.74 years (range: 12-56 years were analyzed. Mean anesthesia duration was 71.75 + 21.08 min. Mean recovery time was 7.6 ± 3.01 min. 16 females and one male patient required additional propofol with a mean dose of 30.8 ± 10.49 mg. No hemodynamic instability was noted. No patient required general anesthesia with endotracheal intubation. The procedure was successful in 93.02% of patients. Four patients developed atrial fibrillation. All patients were satisfied. Conclusion: Conscious sedation using dexmedetomidine is a safe and effective anesthetic technique for percutaneous ASD closure.

    Full Text Available Objective: Atrial septal defect (ASD is the most common congenital heart disease in adults. The aim of this study was to determine the value of surgical closure of ASD in patients over 40 years of age. Materials and Methods: Retrospective analysis of 96 patients with the mean age of 47.58 ± 6.59, who had undergone surgical repair of ASD, was carried out. Pre and postoperative clinical status, New York Heart Association (NYHA functional class and systolic pulmonary artery pressure before and after surgical repair, complications of post operation were assessed and analyzed. The follow-up period was between 1 month and 16 years. Results: Before the operations, 62 patients (89.8% were placed in NYHA functional classes of II and III. However, after the surgeries most of the patients could be placed in the functional classes I and II. The mean of pulmonary artery pressure before the surgeries was about 46.68 ± 14.18 and dropped to 32 ± 11.89 mm Hg after the operations (P < 0.0001. Atrial fibrillation rhythm was present in 18 cases preoperatively which was reduced to 3 patients at the discharge time (16.6%. The mean right ventricular (RV sizes were reduced from 4.1 to 2.5 cm after the surgical repairs. In 35 cases (36.64%, we had no tricuspid valve regurgitation after surgery for RV systolic presser estimation. Conclusion: Surgical closure of ASD in patients over 40 years of age could improve their clinical status, and lead to a reduced pulmonary systolic as well as smaller RV sizes.

    Cerebrovascular disease is one of the most common causes of cerebrovascular morbidity and mortality in developed countries; up to 40% of acute ischemic strokes in young adults are cryptogenic in nature - that is, no cause is determined. However, in more than half of these patients, patent foramen ovale (PFO) is seen along with an increased incidence of atrial septal aneurysm (ASA). The following is a report of an interesting case: a 68-year-old man with ASA and transient cerebral ischemia. Transesophageal echocardiography (TEE) showed the presence of ASA; a test with microbubbles derived from a mixture of air and saline or colloids pointed out a shunt on the foramen ovale following Valsalva's maneuver. The patient underwent percutaneous transcatheter closure of the interatrial communication by an interventional cardiologist. TEE and transcranial Doppler or TEE with the microbubbles test are the recommended methods for detecting and quantifying intracardiac shunts, both at rest and following Valsalva's maneuver. In patients following the first event of transient ischemic attack, and without clinical and anatomical risk factors (such as the presence of ASA, PFO, and basal shunt), pharmacological treatment with antiplatelets or anticoagulants is closely recommended. On the contrary, in patients following the first event of transient ischemic attack, or a recurrent event during antiplatelet treatment, the percutaneous closure of PFO is recommended.

    Full Text Available Background. The relevance of TBX20 gene in heart development has been demonstrated in many animal models, but there are few works that try to elucidate the effect of TBX20 mutations in human congenital heart diseases. In these studies, all missense mutations associated with atrial septal defect (ASD were found in the DNA-binding T-box domain, none in the transcriptional activator domain. Methods. We search for TBX20 mutations in a group of patients with ASD or ventricular septal defect (VSD using the High Resolution Melting (HRM method and DNA sequencing. Results. We report three missense mutations (Y309D, T370O, and M395R within the transcriptional activator domain of human TBX20 that were associated with ASD. Conclusions. This is the first association of TBX20 transcriptional activator domain missense mutations with ASD. These findings could have implications for diagnosis, genetic screening, and patient follow-up.

    Objectives To improve experience of procedure and success rate of interventional treatment of atrial septal defect (ASD) in children, applying the technique of controlling release of devices in the pulmonary vein (controlling two disc of device opening for subsequence) in children cases with ASD who can not be occluded by regularly interventional treatment. Methods Since 2000 year 182 child cases (male 70 and 112 female) underwent the procedure of controlling release of devices in the pulmonary vein. The patients' age was from 2 to 14years old (average 3.77±1.55). The body weight was from 9 to 48 Kg (average 21.53±10.63). When the devices were placed on the right position with difficulty and failure in some cases with short and soft rims of the defect and large defect and the angle between the device and the interval atrial septal (IAS), It could be helpful to put the device into the left upper pulmonary vein, and to make right atrium (proximal) disc opened before the left atrium (distal) disc naturally fall down.At the end the double disc of the device clamped and stood up at the right position of the IAS. After closure of ASD, patients were followed up regularly by echocardiography, X-ray and ECG in the 1,3,6,12month and 3,5 years. Results The successful rate of device implantation in the improving group (98.4%)was obviously higher than that in the regularly group (68%). The techniques improved in this group with the smaller age, the lighter weight, the larger defect and the larger device comparing with the regularly group.The velocity of the pulmonary vein before occlusion procedure was (0.54±0.15)m/s; after procedure was (0.56±0.16)m/s, P > 0.05,there were no significant difference. All cases couldn't found pulmonary congestion by follow up. Conclusions The method of controlling release of device in the pulmonary vein has been used more than 5 years in the occlusion of ASD with double disc device. It is feasible and safety. The aim of the improvement is

    Full Text Available Objectives: This study was aimed to evaluate our clinical experiences and investigate results of percutaneous closure of secundum atrial septal defects (ASD in our clinic.Results: We retrospectively included 70 patients (19 male, 51 female undergoing percutaneous ASD closure procedure with mean age of 36±14.8 (17-75 in our clinic between March 2008 and January 2010. Defect diameter measured by transesophageal echocardiography was 19.7±6.3 mm (6-32 mm. Device size used for percutaneous closure of ASD was 23.7±6.2 (12-36. Devices used for percutaneous closure were nitinol-based devices including Amplatzer (64.7%, Cardiofix (26.7% and biodegredable BioStar (8.6%. The percutaneous closure procedure was successful at 68 of 70 (97% patients. In 2 patients procedure failed. Failure reason was device embolization in one patient and device strut fracture in other; so these 2 patients referred to surgery. During follow up 2 more patients also referred to surgery because of device embolization in first day control. In 3 patients (4.2% supraventricular arrythmias that are converted to sinus by cardioversion are observed. Mean follow up interval was 18.6±9.6 months (1-44 and during this period peripheral vascular complications, cerebrovascular accidents, thrombus on devices, device erosion or death is not observed.Conclusion: Percutaneous closure of secundum ASD which started to replace surgical treatment of ASD in last decades is safe and effective method in short to mid-term period. However because of potentially serious complication risks it should be performed in special centers by operators who are experienced in treating structural heart diseases.

  16. Efficacy of a novel IGS system in atrial septal defect repair

    2013-03-01

    Congenital heart disease occurs in 107.6 out of 10,000 live births, with Atrial Septal Defects (ASD) accounting for 10% of these conditions. Historically, ASDs were treated with open heart surgery using cardiopulmonary bypass, allowing a patch to be sewn over the defect. In 1976, King et al. demonstrated use of a transcatheter occlusion procedure, thus reducing the invasiveness of ASD repair. Localization during these catheter based procedures traditionally has relied on bi-plane fluoroscopy; more recently trans-esophageal echocardiography (TEE) and intra-cardiac echocardiography (ICE) have been used to navigate these procedures. Although there is a high success rate using the transcatheter occlusion procedure, fluoroscopy poses radiation dose risk to both patient and clinician. The impact of this dose to the patients is important as many of those undergoing this procedure are children, who have an increased risk associated with radiation exposure. Their longer life expectancy than adults provides a larger window of opportunity for expressing the damaging effects of ionizing radiation. In addition, epidemiologic studies of exposed populations have demonstrated that children are considerably more sensitive to the carcinogenic effects radiation. Image-guided surgery (IGS) uses pre-operative and intra-operative images to guide surgery or an interventional procedure. Central to every IGS system is a software application capable of processing and displaying patient images, registration between multiple coordinate systems, and interfacing with a tool tracking system. We have developed a novel image-guided surgery framework called Kit for Navigation by Image Focused Exploration (KNIFE). In this work we assess the efficacy of this image-guided navigation system for ASD repair using a series of mock clinical experiments designed to simulate ASD repair device deployment.

  17. Diagnosis of asymptomatic atrial septal aneurysms using two-dimensional color Doppler and contrast transthoracic echocardiography

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    Objective To evaluate the dimensions of atrial septal aneurysm (ASA), the presence and characteristics of interatrial shunt, the movement of the wall of the aneurysm, and correlation between these findings and sign and/or symptoms suggesting embolism in Manisa, a district of a western Anatolian city of Turkey. Methods Two thousand five hundred cases were examined by routine transthoracic echocardiography (TTE) in both pediatric and adult cardiology outpatient clinics. ASA was detected in 20 cases and evaluated by two-dimensional color Doppler echocardiography (CDE). The length of the base, the maximum radius and the maximum displacement of ASA were measured. The shunt between the atria was examined by CDE. In cases where a shunt could not be found, galactose and palmitic acid was injected. Standard 12-lead electrocardiogram (ECG) and exercise stress test were also performed. Results No clinical signs or symptoms were found, suggesting a systemic or cerebral embolism. The maximum displacement of ASA was between 2 and 5 mm. All of the aneurysms were localized in the right atrium, and the walls of the aneurysm did not move beyond the base of the left atrium during the maximum displacement. Interatrial shunt was detected in 14 of 20 patients (70%) by CDE and in the remaining six cases by contrast TTE. Frequent ventricular ectopic beats were observed in one patient. Conclusions During routine TTE we observed 0.8% asymptomatic ASA in our population. The use of a contrast agent was found to be a valuable additional method in patients with ASA when the shunt could not be detected by CDE. The risk for embolism is not high when the maximum displacement of the wall of ASA was 5 mm or less and no bulge into the left atrium was observed. Based on our experience with this method, TTE is easy to perform, well-tolerated and acceptable.

    Full Text Available Background: Atrial Septal Defect (ASD is one of the most common congenital heart diseases that may lead to pulmonary hypertension. Advantages of ASD closure by limited thoracotomy as a minimally invasive approach includes reduction of post-operative complications and improvement of post-operative recovery. Objectives: The present study aimed to assess the safety of right submammary minithoracotomy for repair of ASD in children and to evaluate the cosmetic and functional results of this approach. Patients and Methods: Between August 2010 and August 2013, 35 children underwent heart operations for ASD closure via right submammary thoracotomy. The standard anterolateral thoracotomy technique entailed a 4 - 5 cm right submammary incision. After establishment of cardiopulmonary bypass, the right atrium was opened and defect was closed by pericardial patch. The thoracotomy was closed in a routine fashion. Results: The study patients included 5 males (14.29% and 30 females (85.71% whose age ranged from 1 to 7 years. Among the patients, 30 had ASD and 5 had a sinus venosus type. There were no intraoperative complications regarding exposure, cannulation, or bleeding. There were also no deaths in the post-operative period. Postoperative complications included significant hemorrhage from the suture line in one case and sick sinus syndrome requiring pacemaker implantation in another case. The mean length of stay in the intensive care unit was 2 days and the mean length of hospital stay was 4.5 days. Conclusions: Our study findings indicated that use of right submammary thoracotomy technique to repair ASD could be accomplished safely and provided good short-term results in terms of cosmetics, especially in female patients.

    Atypical left-to-right shunts at the level of the atrium in children such as sinus venosus atrial septal defects (ASDs) and partial anomalous pulmonary venous return (PAPVR) may be difficult to assess by transthoracic or transoesophageal echocardiography. Free-breathing cardiac MRI may be a powerful alternative. To assess the value of free-breathing cardiac MRI in the delineation of atypical ASDs in children. A total of 82 children (mean age 5.9 years, range 1.1-15.7 years) with suspected ASD and inconclusive transthoracic echocardiography underwent cardiac MRI under free-breathing, mostly sedated conditions. Phase-contrast MRI was used for defect visualization and shunt quantification, and multiphase inflow MR angiography for delineation of pulmonary/systemic venous connections. Of the 82 patients, 34 (41%) were diagnosed with atypical shunt lesions at the level of the atrium and 48 (59%) with simple secundum ASDs. No false-negative or false-positive findings were reported by MRI compared to cardiac catheterization and intraoperative findings. Superior sinus venosus ASD with partial anomalous PAPVR was present in 10 of the 82 children (12.2%), whereas 2 (2.4%) had a large posterior-inferior defect, 5 (6.1%) had isolated PAPVR, and 17 (20.7%) had multiple ASDs and/or associated vascular anomalies. Q{sub p}/Q{sub s} by phase-contrast MRI agreed well with oximetry values (mean difference 3%, limits of agreement {+-}21-25%; Bland/Altman analysis). Free-breathing cardiac MRI under sedation allows reliable identification of atypical left-to-right shunt defects at the level of the atrium in children in whom transcatheter ASD closure is unsuitable, including delineation of pulmonary or systemic venous anomalies and shunt quantification.

    Objective To study the validation of ultrasound-based strain rate imaging in the quantitative assessment of right ventricular (RV) function in atrial septal defect (ASD). Methods Tissue Doppler images (TDI) of RV longitudinal and short axes were recorded from the apical 4-chamber view and the subcostal short-axis view in 18 normal controls, 28 children with ASD and 14 children after Amplazter closure of ASD respectively. Peak systolic velocities (V), peak systolic strain rates (SR), peak systolic strains (S) at the basal segment, middle segment of RV lateral wall and the basal septum from the longitudinal axis, the middle segment of RV free wall from the short axis were quantitatively measured using QLAB TM tissue velocity quantification software system respectively. Peak dp/dt from the RV isovolumic contraction determined during the right cardiac catheterization in 28 ASD patients was used as the gold standard of RV contractility. Peak systolic indices were compared against max dp/dt by linear correlation. Results Peak systolic indices at the basal and middle segments of RV lateral wall from the longitudinal axis increased significantly in 28 ASD patients.Peak systolic indices at the basal septum also increased in patient group, but not significantly. Significant decreases in peak systolic indices at the basal and middle segments of RV lateral wall were observed after the Amplatzer closure in 14 ASD patients. There was no significant difference at the middle segment of RV free wall from the short axis between patient group and normal control. A strong correlation was found between max dp/dt and peak systolic indices at the basal and middle segments of RV lateral wall (P<0.05). Conclusion Ultrasound-based strain rate imaging can assess quantitatively RV function in CHD. Peak systolic strains determined at the basal and middle segments of RV lateral wall are strong noninvasive indices of RV contractility.

    Modest secundum atrial septal defects (2°ASD) may cause significant pulmonary over perfusion during infancy, particularly in conjunction with left heart obstructive lesions. Amplatzer Septal Occluders are not ideal in this setting especially given recent concerns regarding device erosion. We report the first use of the Amplatzer Duct Occluder II device (ADO2) to close a 2°ASD in a 4.5 kg infant.

    A 52-year-old man was diagnosed with dextrocardia at the age of 1 year and was asymptomatic until 1 year before admission. He was transferred to our hospital for management of atrial fibrillation. A transthoracic echocardiogram showed dextrocardia with atrial septal defect;moderate tricuspid valve regurgitation; and a large, persistent left superior vena cava. A cardiac catheterization study revealed that pulmonary flow/systemic flow (Qp/Qs) was 3.6 and that pulmonary vascular resistance was 2.5 Wood U·m². Intracardiac repair with tricuspid annuloplasty and a maze procedure was scheduled. When establishing cardiopulmonary bypass, venous drainage was initially obtained from the inferior vena cava and the left superior vena cava, and the small superior vena cava was then directly cannulated after opening the right atrium. The patient's postoperative course was uneventful, and serial electrocardiograms have demonstrated maintenance of normal sinus rhythm for 3.5 years after the operation.

    The purpose of this paper is to review the usefulness of multiplanar transesophageal echocardiography before, during and after percutaneous transcatheter closure of secundum atrial septal defects. Transesophageal echocardiography imaging techniques,including their role in patient selection, procedural guidance and immediate assessment of technical success and complications are described and discussed in this review. Percutaneous transcatheter closure is indicated for ostium secundum atrial septal defects of less than 40 mm in maximal diameter. The defect must have a favorable anatomy, with adequate rims of at least 5 mm to anchor the prosthesis. Transesophageal echocardiography plays a critical role before the procedure in identifying potential candidates for percutaneous closure and to exclude those with unfavorable anatomy or associated lesions, which could not be addressed percutaneously. Transesophageal echocardiography is also important during the procedure to guide the deployment of the device. After device deployment, the echocardiographer must assess the device (integrity, position and stability), residual shunt, atrio-ventricular valve regurgitation, obstruction to systemic or venous return and pericardial effusion, in order to determine procedural success and diagnose immediate complications.

    Full Text Available We report a case wherein a dysmorphic four-month-old infant (weighing 4.5 kgs with an 8 mm atrial septal defect (ASD, a 1.5 mm patent ductus arteriosus (PDA, a 2 mm mid-muscular ventricular septal defect (VSD associated with chronic lung disease, and severe pulmonary hypertension, was successfully managed using a hybrid approach, without the use of cardiopulmonary bypass (CPB. Through a median sternotomy, the PDA was ligated and the ASD was closed with a 9 mm Amplatzer septal occluder implanted through peratrial access. The VSD was left untouched. Serial echocardiograms showed complete closure of the ASD and PDA, with progressive normalization of the pulmonary artery (PA pressures within three months. The child rapidly gained weight and was weaned from sildenafil and oxygen administration. After 12 months, the VSD closed spontaneously and the child remained well, with normal PA pressures. A hybrid approach without the use of CPB should be considered in the management of infants with congenital heart disease, associated with chronic lung disease and pulmonary hypertension.

    Background Ghrelin was found to attenuate the magnitude of pulmonary arterial hypertension and pulmonary vascular remodeling in rats.The objective of this study was to explore the fasting plasma ghrelin level and the relationships between ghrelin and pulmonary arterial pressure (PAP) in atrial septal defect (ASD) patients with pulmonary arterial hypertension (PAH).Methods Fasting plasma ghrelin,obestatin,and insulin levels were measured by enzyme linked immunosorbent assay (ELISA) method in ASD patients with or without PAH according to the manufacturer's instructions.Insulin resistance was calculated by the homeostasis model of assessment for insulin resistance (HOMA-IR) approach,calculated as fasting insulin (microunits/ml)× fasting blood glucose (mmol/L)/22.5.Comparisons between the parameters of patients with PAH and those of patients with normal PAP were performed with an unpaired Student's t test.The relationships between ghrelin and various clinical parameters were examined by bivariate correlations and multiple regression analysis.Results We found that the fasting plasma ghrelin level and the ratio of ghrelin to obestatin were significantly lower in the PAH group compared with the control group ((582.4±12.8) pg/ml vs.(1045.2±95.5) pg/ml,P <0.05 and 30.5±4.9 vs.70.0±9.7,P <0.01).The fasting plasma obestatin level was higher in the PAH group compared with the control group,but the difference between them was not significant ((23.2±3.1) pg/ml vs.(16.3±1.6) pg/ml,P >0.05).In a multiple regression model analysis,only mean PAP was an independent predictor of ghrelin and the ratio of ghrelin to obestatin (standardized coefficient=0.737,P <0.001 and standardized coefficient=-0.588,P=0.006,respectively).Conclusion Ghrelin is negatively correlated with mean PAP and this suggests that circulating ghrelin might predict the severity of pulmonary hypertension in ASD patients with PAH.

    AIM: To investigate long-term efficacy of two different devices more than five years after percutaneous atrial septal defect(ASD) closure in adults.METHODS: All patients who underwent percutaneous closure of an ASD in the St. Antonius Hospital, Nieuwegein, The Netherlands, between February 1998 and December 2006 were included. Percutaneous closure took place under general anaesthesia and transesophageal echocardiographic moni toring. Transthoracic echocardiography(TTE) was performed 24 h post-procedure to visualize the device position and to look for residual shunting using color Doppler. All complications were registered. All patients were invited for an outpatient visit and contrast TTE more than 5-years after closure. Efficacy was based on the presence of a residual right-to-left shunt(RLS), graded as minimal, moderate or severe. The presence of a residual left-to-right shunt(LRS) was diagnosed using color Doppler, and was not graded. Descriptive statistics were used for patients’ characteristics. Univariate analysis was used to identify predictors for residual shunting.RESULTS: In total, 104 patients(mean age 45.5 ± 17.1 years) underwent percutaneous ASD closure using an Amplatzer device(ASO) in 76 patients and a Cardioseal/Starflex device(CS/SF) in 28 patients. The mean follow-up was 6.4 ± 3.4 years. Device migration occurred in 4 patients of whom two cases occurred during the index hospitalization(1 ASO, 1 CS/SF). The other 2 cases of device migration occurred during the first 6 mo of follow-up(2 CS/SF). The recurrent thrombo-embolic event rate was similar in both groups: 0.4% per follow-up year. More than 12 mo post-ASD closure and latest follow-up, new-onset supraventricular tachyarrhythmia’s occurred in 3.9% and 0% for the ASO and CS/SF group, respectively. The RLS rate at latest follow-up was 17.4%(minimal 10.9%, moderate 2.2%, severe 4.3%) and 45.5%(minimal 27.3%, moderate 18.2%, severe 0%) for the ASO- and CS/SF groups, respectively. There was no

    Full Text Available Objective:Transcatheter closure of secundum atrial septal defect (ASD with Amplatzer device is an alternative procedure to surgical repair, with some limitations. The aim of this study was to assess the initial and mid-term results of the treatment of ASD with Amplatzer septal occluder in children and adolescents. Methods:From May 2003 to January 2008 sixty three consecutive children and adolescent patients underwent transcatheter closure of ASD at a mean±SD age of 8.5±4.8 years (range 2.2 to 18 years. All procedures were performed under local anesthesia and moderate sedation or general anesthesia with transthoracic echocardiography and fluoroscopic guidance. Stretch diameter of ASD was determined by balloon sizing catheter. Device selection was based on and matched to the standard diameter of the septal defect. Follow up at 24 hours, 1 month, 6 months, 12 months and yearly thereafter included physical examination, electrocardiography and transthoracic echocardiography. Findings:The mean ASD diameter, measured with transthoracic echocardiography and balloon catheter were 19.5± 5.5 mm and 20.9± 6.2 mm, respectively. The mean follow up period was 32.4±18.8 months. Deployment of the device was successful in 57 (90.5% and failed in 6 (9.5% patients. The major complication included dislodgement of device in 1 patient and device embolization to right ventricular inlet (surgically removed in 1 patient. The minor complication included transient atrial tachycardia in 10 patients, paroxysmal supraventricular tachycardia in 2 patients during procedure, successfully terminated with medication. At 24 hour, 1 month, 6 month and 1 year follow up, total occlusion rates were 73.6 %, 91%, 94.7%, and 94.7%, respectively. Conclusion:Transcatheter occlusion of ASD with Amplatzer device is an effective and safe procedure with minimal complication rate and short hospital stay, as well as excellent short and intermediate outcome in children and adolescents.

    2015-01-01

    Full Text Available Sinus venosus atrial septal defects (SV-ASD have nonspecific clinical presentations and represent a diagnostic imaging challenge. Transthoracic echocardiography (TTE remains the initial diagnostic imaging modality. However, detection rates have been as low as 12%. Transesophageal echocardiography (TEE improves diagnostic accuracy though it may not detect commonly associated partial anomalous pulmonary venous return (PAPVR. Cardiac magnetic resonance (CMR imaging provides a noninvasive, highly sensitive and specific imaging modality of SV-ASD. We describe a case of an adult male with exercise-induced, paroxysmal supraventricular tachycardia who presented with palpitations and dyspnea. Despite nondiagnostic imaging results on TTE, CMR proved to be instrumental in visualizing a hemodynamically significant SV-ASD with PAPVR that ultimately led to surgical correction.

    Full Text Available Background: Transcatheter closure of atrial septal defect secundum (ASD-II has become an alternative method for surgery. We sought to compare the two-dimensional transesophageal echocardiography (TEE method for measuring atrial septal defect with balloon occlusive diameter (BOD in transcatheter ASD-II closure.Methods: A total of 39 patients (71.1% female, mean age: 35.31 ± 15.37 years who underwent successful transcatheter closure of ASD-II between November 2005 and July 2008 were enrolled in this study. Transthoracic echocardiography (TTE and TEE were performed to select suitable cases for device closure and measure the defect size before the procedure, and BOD measurement was performed during catheterization via TEE. The final size of the selected device was usually either equal to or 1 – 2 mm larger than the BOD of the defect.Results: The mean defect size obtained by TEE and BOD was 18.50 ± 5.08 mm and 22.86 ± 4.76 mm, respectively. The mean difference between the values of ASD size obtained by TEE and BOD was 4.36 ± 2.93 mm. In comparison with BOD, TEE underestimated the defect size in 94.9%, but TEE value being equal to BOD was observed in 5.1%. There was a good linear correlation between the two measurements: BOD = 0.773 × ASD size by TEE+8.562; r2 = 67.9.1%. A negative correlation was found between TEE sizing and the difference between BOD and TEE values (r = -0.394, p value = 0.013.Conclusion: In this study, BOD was larger than ASD size obtained by two-dimensional TEE. However, TEE maximal defect sizing correlates with BOD and may provide credible information in device size selection for transcatheter ASD closure.

    Vessels of Wearn are rare findings during coronary angiography in adults. They are known to be associated with forms of cyanotic congenital heart disease in infants but we are not aware of any published cases of association with non-cyanotic left to right shunts in adults. We present the case of a 69-year-old man with angiographically evident vessels of Wearn draining from the left and right coronary arteries into the left ventricle associated with an asymptomatic atrial septal defect. We postulate a developmental phase association between atrial septal maturation and closure of perfusing microchannels from the ventricular cavities to the epicardial coronary arteries on the same spectrum as that which leads to more widespread defects in infants. We also highlight a common medication side effect that might have been mistaken as a manifestation of the congenital anomalies.

    The diagnosis of multiple atrial septal defects is less challenging with 3-D transesophageal echocardiography. However, the common occurrence of echo drop-out (acoustic shadow) artifacts with 3-D echocardiography can make the differentiation between a second defect and an artifact challenging. Agitated saline injection with direct visualization using 3-D echocardiography can help resolve this by allowing visualization of the bubbles crossing from true defects.

    Background and objectives Right ventricular apical (RVA) pacing has been reported impairing left ventricular (LV)performance. Alternative pacing sites in right ventricle (RV) has been explored to obtain better cardiac function. Our study was designed to compare the hemodynamic effects of right ventricular septal (RVS) pacing with RVA pacing. Methods Ten elderly patients with chronic atrial fibrillation (AF) and long RR interval or slow ventricular response (VR) received VVI pacing. The hemodynamic difference between RVS and RVA pacing were examined by transthoracic echocardiography (TTE). Results Pacing leads were implanted successfully at the RVA and then RVS in all patients without complication. The left ventricular (LV) parameters,measured during RVA pacing including left ventricular ejection fraction (LVEF), FS, stroke volume (SV) and peak E wave velocity (EV) were decreased significantly compared to baseline data, while during RVS pacing, they were significantly better than those during RVA pacing. However, after 3-6 weeks there was no statistical significant difference between pre- and post- RVS pacing.Conclusions The LV hemodynamic parameters during RVA pacing were significantly worse than baseline data. The short term LV hemodynamic parameters of RVS pacing were significantly better than those of RVA pacing; RVS pacing could improve the hemodynamic effect through maintaining normal ventricular activation sequence and biventricular contraction synchrony in patients with chronic AF and slow ventricular response.

    2012-08-01

    Full Text Available Symptomatic pulmonary arterial hypertension (PAH in patients with isolated atrial septal defect (ASD is rare during infancy. We report a case of isolated ASD with severe PAH in an infant who developed airway obstruction as cardiomegaly progressed. The patient presented with recurrent severe respiratory insufficiency and failure to thrive before the repair of the ASD. Echocardiography confirmed volume overload on the right side of heart and severe PAH (tricuspid regurgitation [TR] with a peak pressure gradient of 55 to 60 mmHg. The chest radiographs demonstrated severe collapse of both lung fields, and a computed tomography scan showed narrowing of the main bronchus because of an intrinsic cause, as well as a dilated pulmonary artery compressing the main bronchus on the left and the intermediate bronchus on the right. ASD patch closure was performed when the infant was 8 months old. After the repair of the ASD, echocardiography showed improvement of PAH (TR with a peak pressure gradient of 22 to 26 mmHg, and the patient has not developed recurrent respiratory infections while showing successful catch-up growth. In infants with symptomatic isolated ASD, especially in those with respiratory insufficiency associated with severe PAH, extrinsic airway compression should be considered. Correcting any congenital heart diseases in these patients may improve their symptoms.

    Background Incomplete right bundle branch block (ICRBBB) is commonly associated with atrial septal defect (ASD),but lacks sufficient diagnostic test characteristics.An abnormal T wave is also often observed in ASD,with horizontal or inverted displacement of the proximal T wave limb in the right precordial leads,termed "defective T wave" (DTW).Methods We examined the diagnostic test characteristics of combining ICRBBB with DTVV as a new index to diagnose ASD.A total of 132 consecutive patients with ASD and 132 cases of age/gender-matched controls without ASD were enrolled.Results Sensitivities of DTW,ICRBBB,and both were 87.1%-87.9%.Specificities were 97.0%,96.2%,and 100%,respectively.Positive predictive values were 1.3%,1.1%,and 100.0% respectively,while negative predictive values were 99.9% for each.Conclusion Combining ICRBBB with DTW in electrocardiogram (ECG) as a new index significantly increased the specificity and positive predictive values while maintaining a high sensitivity in diagnosing ASD.

    Full Text Available A hypertensive 76-year-old man with severe pulmonary valve stenosis (PVS and recent initiation of haemodialysis was referred with fever, chills, and asthenia. One month prior, he had been admitted with similar symptoms. Transthoracic echocardiography (TTE had shown a PVS and no valve vegetations were observed. Following discharge, he was readmitted with fever and blood cultures positive for Staphylococcus haemolyticus. A new TTE revealed two pulmonary valve vegetations and a previously undetected ostium secundum-type atrial septal defect (ASD, confirmed by transesophageal echocardiography. The clinical course was uneventful with intravenous antibiotic treatment and the patient was safely discharged. This is a case of pulmonary valve infective endocarditis (IE. The incidence of right-sided IE is on the rise due to the increased number of patients using central venous lines, pacing, haemodialysis and other intravascular devices. Pulmonary valve IE is extremely rare, especially in structurally normal hearts. The case reported here, presents a combination of predisposing factors, such as severe congenital PVS, the presence of a central venous catheter, and haemodialysis. The fact that it was an older patient with severe congenital PVS and associated with a previously undiagnosed ASD, is also an unusual feature of this case, making it even more interesting.

    Full Text Available Ensuring safety of young athletes and employees who perform hard physical work within the scope of their professional duties, with a special focus on prevention of a sudden cardiac death at sports fields or during hard physical work is one of the most important tasks, which demands joint effort of cardiologists and sport physicians or occupational physicians, who qualify patients for a job or a sport discipline. Apart from hypertrophic and arhythmogenic right ventricular cardiomyopathy, coronary anomalies and aortic dissection belong to the most frequent causes of dramatic complications during competitive exercise or work with an increased energy expenditure. Although a detailed medical history and a physical examination combined with 12-lead ECG assessment may significantly improve the safety in competitive sports, adding echocardiography examination gives a detailed and noninvasive insight into the heart morphology and function. Therefore, in our opinion, it should constitute a standard part of the evaluation of candidates for competitive sports. The practice indicates that beyond subjects with severe heart diseases and those classified as normal, there is a group of individuals with abnormalities which should be more closely monitored, but are not contraindications against professional sports or work with an increased energy expenditure. We describe the case of a young female with a diagnosis of rare congenital aortic valve disease, quadricuspid valve, with mild regurgitation and atrial septal aneurysm which was established during transthoracic echocardiography and confirmed and expanded during TEE examination.

    We report a case of acute left ventricular failure at one hour after transcatheter closure of a secundum atrial septal defect (ASD) in a 28-year-old man with hypertrophic cardiomyopathy. Afforded noninvasive mechanical ventilation and the administration of intravenous morphine and high doses of furosemide, the patient exhibited improvement of his clinical condition, redtion of pulmonary congestion at chest X-ray, and satisfactory blood gas analyses in twelve hours. Twentyfour hours later, the patient received oral administration of furosemide and metoprolol. After 7 days the patient was discharged in good clinical condition. At follow-up at 12 months, the patient had remained symptomatically improved from NYHA Class Ⅲ symptoms before the procedure to Class Ⅱ symptoms. There was no latent arrhythmia at the follow-up examination. Follow-up transthoracic echocardiography estimated an improvement of the left ventricular function. So,transcatheter closure of a secundum ASD in a patient with hypertrophic cardiomyopathy is feasible, and a thorough understanding of the hemodynamic condition of ASD and hypertrophic cardiomyopathy will reduce the complication of ASD closure.

  6. Differences in atrial septal activation with an intrasinoatrial nodal pacemaker and epicardial sinoatrial nodal pacing.

    Goldberg, J M

    Changes in Intra-SA nodal pacemaker localization were produced through stimulation of the decentralized cervical vagi and stellate ganglia in the anesthetized dog. Shifts in pacemaker to the rostral, middle, or caudal regions of the SA node produced a change in the timing as well as a change in the sequence of activation of recording sites overlying the AV node. Epicardial pacing with a plaque electrode from either the rostral, middle, or caudal regions of the SA node produced the same activation sequence of the AV nodal electrodes irrespective of the epicardial SA nodal pacing site. The inability of epicardial SA nodal pacing to precisely reproduce the activation pattern of the atrial septum overlying the AV node observed with a natural SA nodal pacemaker can be explained by the geographic relationship of the pacemaker cells within the node to the preferential internodal pathways and the area of atrial tissue stimulated by pacing. Pacing activates a large mass of tissue, whereas an intrinsic pacemaker probably acts as a more localized focus. The inability of pacing to reproduce the activation pattern seen with spontaneous rhythm may be a determinant in the varied P wave morphology seen with coronary sinus or AV nodal junctional rhythms, as compared with more consistent morphology seen with pacing.

    We investigated the mid-to-long-term results of transcatheter closure of atrial septal defect (ASD) in patients ≥40 years since there are issues with patients presenting with pulmonary hypertension and arrhythmia at the time of closure. In an 8.8 year period, transcatheter closure of ASD was successful in 179 patients aged ≥40 years, but failed in 2. Of the 179 patients (44 males, median 53 years), NYHA functional class, presence of arrhythmia and severity of pulmonary hypertension were compared before and after closure. Patients with pulmonary hypertension (n = 43, 24 %) were significantly older (60 ± 11 vs. 52 ± 9 years, p atrial fibrillation (AF), 4 atrial flutter and 5 supraventricular tachycardia. Patients with AF or atrial flutter (n = 26) were significantly older (63 ± 10 vs. 53 ± 10 years, p = 0.048) and had a higher pulmonary artery mean pressure (29.2 ± 12.6 vs. 20.2 ± 7.6 mmHg, p = 0.041) than those without. The mean follow-up period was 3.8 ± 2.1 years. Early new-onset arrhythmia was documented in 23 patients of whom 1 had persistent AF, 1 developed sick sinus syndrome and others were in sinus rhythm at latest visit. There was significant improvement in NYHA functional class after closure (p paroxysmal AF, and 11 had persistent AF. Pulmonary hypertension persisted in 13 patients. Transcatheter closure of atrial septal defect in patients above 40 years is beneficial in terms of NYHA functional class, pulmonary artery pressure and cardiac rhythm.

    Atrial septal defect (ASD) occlusion devices made of nickel–titanium (NiTi) have a major shortcoming in that they release nickel into the body. We modified NiTi occluders using Arc Ion Plating technology. Nano lamellar titanium–nitrogen (TiN) coatings were formed on the surfaces of the occluders. The safety and efficacy of the modified NiTi occluders were evaluated in animal model. The results showed that 38 out of 39 rams (97%) survived at the end of the experiment. Fibrous capsules formed on the surfaces of the devices. Gradual endothelialization took place through the attachment of endothelial progenitor cells from the blood and the migration of endothelial cells from adjacent endocardium. The neo-endocardium formed more quickly in the coated group than in the uncoated group, as indicated by the evaluation of the six month study group. After TiN coating, there was no significant difference in endothelial cell cycle. TiN coating significantly reduced the release of nickel in both in vivo and in vitro indicating an improved biocompatibility of the nitinol ASD occluders. Superior and modified ASD occluders may provide a good choice for people with nickel allergies after sFDA registration, which is expected in one to two years. - Highlights: ► The nano lamella TiN coating did not change the shape-memory behavior and flexibility of the nitinol occluder. ► Nano lamella TiN coating modifications significantly reduced nickel release from nitinol ASD occluder. ► The new ASD occluder was found to be superior to nitinol ASD occluder with respect to both safety and efficacy.

    Background Very few published data is available on the outcomes of balloon assisted techniques (BATs) for trans catheter closure (TCC) of very large (Defined as ≥35 mm size) ostium secundum atrial septal defect (ASD). Objective To study the utility of BAT as against conventional techniques (CT) in TCC of very large ostium secundum ASD (≥35 mm) over the past 5-year period and to find out the association of different morphological features of the defects in relation to TCC outcomes. Study design and methods Descriptive single center retrospective study of patients with very large ostium secundum ASD (≥35 mm size) who were subjected to TCC. Results Thirty-three out of 36 patients with ≥35 mm ASD and complex morphological features underwent successful TCC. The study patients had high prevalence of absent aortic and posterior rims with posterior mal-alignment of the septum. BAT was successful in 28/31 (90.3%) patients while CT had a success rate of 16%. The mean trans-esophageal echocardiography (TEE) ASD size with BAT success 37 (SD 1.3) mm and CT failure 36.2 (SD 1.1) mm was not different (P=0.06). On univariate analysis of different morphological features, posterior mal alignment of the septum was associated failure of CT (P=0.01). There was no urgent referral for surgery and patients did well on follow up. Conclusions Balloon assisted device closure of (≥35 mm) ASD had 90% success rate. BAT helps in controlled delivery and device alignment in very large ASD with posterior malalignment of the septum and is often helpful when CT fails. PMID:24649421

    Full Text Available Objective  To assess the safety and efficiency of robotic minimally invasive surgery and transcatheter interventional occlusion for treatment of adult secundum atrial septal defect (ASD by comparing the early and recent postoperative follow-up results of the two minimally invasive surgery. Methods  Thirty adult patients with secundum ASD, who admitted to the General Hospital of PLA from Jan. 2008 to Dec. 2014 and received treatment of da Vinci Surgical System, were recruited as TEASD-R group, meanwhile, another 30 adult patients who received transcatheter interventional occlusion were recruited under the strict 1:1 criterion as TIASD-O group. The early postoperative complications, in-hospital conditions, recent postoperative follow-up results and the quality of life 30d and 6 months after operation were compared and retrospectively analyzed between the two groups. Results  The success rates of surgery were 100% in the both groups, no early and recent postoperative complications (residual shunt, pericardial effusion, cerebral infarction, peripheral vascular embolism, new arrhythmia, etc. were found in TEASD-R group. While some of corresponding complications existed in TISAD-O group, and the differences were of statistical significance (P<0.05 between the two groups in the incidence of postoperative new arrhythmia, tricuspid incompetence and pulmonary hypertension, as well as in the early size of right atrium and in-hospital time. SF-36 quality of life questionnaire showed that the difference of somatic pain 30d after operation was of statistical significance (P<0.05 between the two groups, but the difference disappeared 6 months after operation. Conclusion  Robotic minimally invasive surgery for adult secundum ASD is feasible, safe and efficacious since no postoperative complications occurred such as tricuspid incompetence and pulmonary hypertension, but the longer operative and inhosptial time are the shortages of the operation.

    Objective Assessment of right ventricular function in patients with atrial septal defect (ASD) is difficult. The Doppler myocardial performance index (MPI) may provide a method of assessing function in these patients. The purposes of this study were to evaluate the right ventricular function and its changes in patients with ASD after transcatheter closure of ASD. Methods MPI, defined as the sum of isovolumic relaxation time and isovolumic contraction time derived by ejection time, was measured from tricuspid inflow and right ventricular outflow; Doppler velocity profiles recorded during routine echocardiography. Twenty nine patients ( 13 men, 16 women;mean age 25.28 ± 12.69, range 6 to 57 years) were diagnosed to secundum ASD [the stretched diameters of ASD were from 9 To 36 (24.91 ±7.98) mm], and had a successfully placed Amplatzer septal occluder (ASO) (the sizes of ASO were from 11 to 40 mm ); there were 81 sex-matched, age-matched healthy people (control group 41men, 40 women; mean age 29.02 ± 14.22, range 4 to 45 years).MPI was measured again on 3 days and 1 month after closure of ASD. Change in the study group was assessed and compared to the control subjects with structurally normal hearts. A complete 2- dimensional and Doppler echocardiographic examination was performed in all study groups. Results 1) The isovolumic relaxation and isovolumic contraction times [respectively(77.59 ± 14.39)ms vs (60.93 ± 12.94)ms, P<0.0001; (28.28 ± 10.88)ms vs (23.64 ± 9.01)ms, P=0.027] were prolonged, and ejection time [(260.65 ± 21.86 )ms vs (271.85 ± 21.92)ms, P=0.033] was shortened in patients with ASD compared with that in control subjects, resulting in a marked increase in the MPI(0.40 ± 0.07 vs 0.31 ± 0.05, P<0.0001) from normal values; 2) by Pearson's correlations, the MPI had no correlation with heart rate and blood pressure in control subjects and patients with ASD, but it correlated positively with age in patients with ASD; 3) by Pearson

    Iatrogenic erosion of the septum primum after foramen ovale closure is an anecdotal event. We report the case of a 39-year-old woman admitted to our institution for multifocal cryptogenic cerebral ischemia and a patent foramen ovale (PFO) associated with an aneurysm of the septum primum. The patient underwent percutaneous closure of the PFO with an Amplatzer PFO Occluder device. At the 6-months follow up, the device was in the right position, but a jagged defect of the septum primum and evidence of significant left-to-right shunting was detected. The atrial septal defect was then repaired by a surgical approach. Although this event is not life-threatening, it should be considered as a therapeutic pitfall, resulting in a risk of paradoxical embolism recurrences and long-term hemodynamic impairment. © 2013 Wiley Periodicals, Inc.

    Device closure of atrial septal defect (ASD) is sometimes followed by elevation of plasma brain natriuretic peptide (BNP), a marker of heart failure, and progression to heart failure. This study tested the hypothesis that the underlying diastolic dysfunction, assessed on tissue Doppler images (TDI) before device closure, can predict BNP level after ASD closure. The study subjects were 39 consecutive patients (age 27.5 +/- 16.3 years, range 5 to 63) who underwent device closure for ASD. Echocardiographic evaluation using TDI and 2-dimensional and pulse wave Doppler were performed, together with plasma BNP measurement 1 day before and 2 days after ASD closure. Before ASD closure, an age-dependent decrease was noted in left ventricular relaxation, assessed by early diastolic mitral annular velocity. ASD closure resulted in a decrease in early diastolic mitral annular velocity (from 14.7 to 12.3 cm/s, p linear regression identified early diastolic mitral annular velocity before ASD closure and age as independent predictors of BNP levels after ASD closure (p annular velocity developed exertional dyspnea after the procedure. In conclusion, our results indicate that TDI measurements could be useful to detect underlying diastolic dysfunction that can potentially cause heart failure after ASD closure and emphasize the importance of ASD closure at a young age before impairment of left ventricular relaxation.

    GATA4 is expressed early in the developing heart where it plays a key role in regulating the expression of genes encoding myocardial contractile proteins. Gene mutations in the human GATA4 have been implicated in various congenital heart defects (CHD), including atrial septal defect (ASD). Although ASD is the third most common CHD in humans, it is generally rare in dogs and cats. There is also no obvious predilection for ASD in dogs and cats, based on sex or breed. However, among dogs, the incidence rate of ASD is relatively high in Samoyeds and Doberman Pinschers, where its inheritance and genetic aetiology are not well understood. In this study, we identified and investigated the genetic aetiology of an ASD affected family in a pure breed dog population. Although the GATA4 gene was screened, we did not find any mutations that would result in the alteration of the coding sequence and hence, the predicted GATA4 structure and function. Although the aetiology of ASD is multifactorial, our findings indicate that GATA4 may not be responsible for the ASD in the dogs used in this study. However, this does not eliminate GATA4 as a candidate for ASD in other dog breeds.

    Full Text Available Neonatal asymptomatic suprarrenal hemorrhage is relatively frequent; sometimes it is detected only after resolution when a calcification is found; symptomatic forms are rare; most times hemorrhage and hematoma are due to an obstetric trauma and are related to macrosomia, breech presentation, maternal diabetes and neonatal hypoxia. Clinical picture is characterized by abdominal mass and anemia; diagnosis is confirmed by imagenology. Two patients with suprarrenal hematoma from the University Hospital at Cartagena, Colombia, are presented. Both were related with traumatic delivery and cephalohematoma; one of them had oral and gastric bleeding and the othersuffered hematoma infection; diagnosis was done with abdominal ecography and CAT. Both patients recovered with medical treatment. La hemorragia suprarrenal asintomática del neonato es relativamente frecuente y muchas veces se detecta como una calcificación local después de que se resuelve el hematoma. La forma sintomática es rara y, a menudo, se debe a un trauma obstétrico relacionado con la macrosomía fetal, la presentación podálica, la diabetes materna o la hipoxia perinatal. Las manifestaciones clínicas son, principalmente, una masa abdominal y anemia importante; el diagnóstico se confirma con la imaginología. Se presentan dos casos de hematoma suprarrenal derecho tratados en el Hospital Universitario de Cartagena, ambos relacionados con un parto traumático y acompañados de cefalohematomas; uno de ellos presentó sangrado gastrointestinal alto y el otro infección del hematoma suprarrenal. El diagnóstico se comprobó con la ecografía abdominal y se verificó con la tomografía. El tratamiento fue médico y no se requirió cirugía a pesar de la anemia severa que presentó uno de los pacientes.

    We report on a child with dextrocardia, atrial septal defect (ASD), severe developmental delay, hypotonia, 13 pairs of ribs, left preauricular choristoma, hirsutism, and craniofacial abnormalities. Prenatal cytogenetic evaluation showed karyotype 46,XY,?dup(8p)ish del(8)pter. Postnatal array CGH demonstrated a 6.8 Mb terminal deletion at 8p23.3-p23, an interstitial 31.1 Mb duplication within 8p23.1-p11, and a terminal duplication of 0.24 Mb at 22q13.33, refining the karyotype to 46,XY,der(8)dup(8)(p23.1p11.1)t(8;22)(p23.1;q13.1).ish der(8)dup(8)(p23.1p11.1)t(8;22)(p23.1;q13.1) (D8S504-,MS607 + ,ARSA + ,D8Z1 + , RP115713 + +). Previous reports of distal 8p deletion, 8p duplication, and distal 22q duplication have shown similar manifestations, including congenital heart disease, intellectual impairment, and multiple minor anomalies. We correlate the patient's clinical findings with these particular areas of copy number. This case study supports the use of aCGH to identify subtle chromosomal rearrangement in infants with cardiac malformation as their most significant or only apparent birth defect. Additionally, it illustrates why aCGH is essential in the description of chromosome rearrangements, even those seemingly visible via routine karyotype. This method shows that there is often greater complexity submicroscopically, essential to an adequate understanding of a patient's genotype and phenotype.

    Objectives To explore how transthoracic atrial septal defect closure affect atrioventricular valve regurgitation. Methods Retrospective reviews of 43 patients who underwent closure of atrial septal defects in Zhujiang Hospital from January 2002 to March 2011 were included in this study. Among them,40 patients were guided by transesophageal echocardiography, while 2 patients were observed by transthoracic echocardiography. All the patients' cardio parameters, complications and extent of atrioventricular valve regurgitation were followed up with echocardiography before and after operation. Results Of the 43 patients,41 (95.3%) cases were successful, 1 patient was given right transthoracic minimally invasive closure of atrial septal defects under cardiopulmonary bypass, and 1 patient died of cardiac arrest during operation. Acute renal failure appeared in 1 patient 2 days afer operation. Twelve patients were observed leakage from left atrial to right atrial immediately after operation, but the syndrome disappeared one month later. Transthoracic echocardiography demonstrated that right atrial diameter and right ventricular diameter decreased, while left ventricular diameter enlarged, pulmonary blood velocity reduced sharply. The differences were significant (P0.05). Mitral vaive regurgitation became worse at the time of 1 month and 6 months after operation. The difference was significant when compared with that before operation (rank; 2.01 vs. 2.17 vs. 1.77, ^ = 10.78 ,P=Q.04). Meanwhile, tricuspid valve regurgitation hardly changed (rank; 1.88 vs. 2.11 vs. 2.01, ^2=4.23 ,P=0.134). Conclusions Transthoracic closure of atrial septal defects may worsen mitral valve regurgitation, while it has no obvious influence on tricuspid valve regurgitation for a short time. Patients who had moderate or above mitral valve regurgitation or severe tricuspid valve regurgitation may not be suitable for isolated atrial septal defect closure.%目的 探讨经胸房间隔缺损封堵术

    Objective To investigate whether transcatheter closure of atrial septal defect makes cardiac troponin I(cTnI) realease in children. Methods Clinical data, laboratory tests, imagings, diagnosis, the information of interventional therapy and postoperative follow-up from 146 children with secundum atrial septal defect who were diagnosed and get treatment of interventional were collected. The median age was(5. 87 ± 3. 48) years( range,2. 25-12. 5) with 87 boys and 59 girls. The device size ranged from 8 to 22 mm. These patients were divided to 2 groups according to the level of cTnI after intervention. The cTnI serum concentrations were examined immediately eafter intervention ,6 hours later,24 hours later and 3 days after intervention. Results The level of cTnI were normal before intervention,and the peak level of cTnI was found at 6 hours after intervention(Z = - 3. 410,P =0. 005) . All of the patients had a normal level of cTnI 3 days after operation ( Z = - 0. 332, P = 0. 74 ) . Univariate analysis showed age, height,device size,size/BSA ratio to be contributing factors for level of cTnI. The device size/body surface area ratio was identified by demonstration positive correlation with cTnI elevation by multivariate logistic regression analysis ( r = 0. 31, P =0. 022 ). Conclusions The transcatheter closure of atrial septal defect in children could lead to reversible increase of cTnI or induce minor myocardial lesion, the extent of which depends on the ratio of device size/ body surface area. Interventional therapy of atrial septal defect is safe and effective for children.%目的 总结并分析儿童继发孔型房间隔缺损患者接受介入封堵治疗前后肌钙蛋白I(cTnI)变化的原因及相关因素,提高临床医师对介入封堵技术治疗儿童房间隔缺损相关适应证及手术风险的了解.方法 收集146例2009年9月至2012年4月在上海儿童医学中心心内科介入封堵的继发孔型房间隔缺损患儿的临床资料、辅

    Full Text Available Abstract Background Intraseptal hematoma and subsequent myocardial infarction due to accidental contrast agent deposition complicating diagnostic cineventriculography is a previously undescribed complication of angiography. Case presentation A 61 year old man was admitted at intensive care unit because of unstable angina pectoris 1 hour after coronary angiography. Transthoracic contrast echocardiography showed a non-perfused area in the middle of interventricular septum with an increase of thickening up to 26 mm. Review of cineventriculography revealed contrast enhancement in the interventricular septum after contrast medium injection and a dislocation of the pigtail catheter tip. Follow up by echocardiography and MRI showed, that intramural hematoma has resolved after 6 weeks. After 8 weeks successful stent implantation in LAD was performed and after 6 month the patient had a normal LV-function without ischemic signs or septal thickening demonstrated by stressechocardiography. Conclusion A safe and mobile position of the pigtail catheter during ventriculography in the middle of the LV cavity should be ensured to avoid this potentially life-threatening complication. For assessment and absolute measurement of intramural hematoma contrast-enhanced echocardiography is more feasible than MRI and makes interchangeable results.

    Full Text Available Atrial septal defect (ASD is the third most frequent type of congenital heart anomaly, featuring shunting of blood between the two atria. Gene-environment interaction remains to be an acknowledged cause for ASD occurrence. A recent European genome-wide association study (GWAS of congenital heart disease (CHD identified 3 susceptibility SNPs at chromosome 4p16 associated with ASD: rs870142, rs16835979 and rs6824295. A Chinese-GWAS of CHD conducted in the corresponding period did not reveal the 3 susceptibility SNPs, but reported 2 different risk SNPs: rs2474937 and rs1531070. Therefore, we aimed to investigate the associations between the 3 European GWAS-identified susceptibility SNPs and ASD risk in the Han population in southwest China. Additionally, to increase the robustness of our current analysis, we conducted a meta-analysis combining published studies and our current case-control study. We performed association, linkage disequilibrium, and haplotype analysis among the 3 SNPs in 190 ASD cases and 225 age-, sex-, and ethnicity-matched healthy controls. Genotype and allele frequencies among the 3 SNPs showed statistically significant differences between the cases and controls. Our study found that individuals carrying the allele T of rs870142, the allele A of rs16835979, and the allele T of rs6824295 had a respective 50.1% (odds ratio (OR = 1.501, 95% confidence interval (CI = 1.122-2.009, PFDR-BH = 0.018, 48.5% (OR = 1.485, 95%CI = 1.109-1.987, PFDR-BH = 0.012, and 38.6% (OR = 1.386, 95%CI = 1.042-1.844, PFDR-BH = 0.025 increased risk to develop ASD than wild-type allele carriers in our study cohort. In the haplotype analysis, we identified a disease-risk haplotype (TAT (OR = 1.540, 95%CI = 1.030-2.380, PFDR-BH = 0.016. Our meta-analysis also showed that the investigated SNP was associated with ASD risk (combined OR (95%CI = 1.35 (1.24-1.46, P < 0.00001. Our study provides compelling evidence to motivate better understanding of the etiology

    2013-01-01

    Postoperative extradural hematoma (POEH) is a possible complication after head surgery, often neglected in the literature. In a single surgeon experience we found 13 cases of POEH (0.8%). We distinguished two subtypes: (1) larger hematomas (>40 cc) with typical features and overt clinical picture that always needed evacuation, and (2) smaller hematomas (<40 cc) with insidious clinical onset and different radiological features compared with traumatic and spontaneous extradural hematomas. On the basis of our experience, we propose that clinical picture and radiologic appearance lead the decision between conservative or interventional treatment of type II hematomas.

    Full Text Available Background: Acute bilateral extradural hematoma is a rare presentation of head trauma injury. In sporadic cases, they represent 0.5-10% of all extradural hematomas. However, higher mortality rates have been reported in previous series. Case Description: The authors described the case of a 28-year-old male presenting head injury, comatose, Glasgow Coma Scale of 6, anisocoric pupils without puppilary light reflex. Computed tomography showed asymmetric bilateral epidural hematomas, effacement of the lateral ventricles and sulci, midline shift and a bilateral skull fracture reaching the vertex. Surgical evacuation was performed with simultaneous hematoma drainage. Patient was discharged on the 29 th postoperative day with no neurological deficit. Conclusion: The correct approach on bilateral epidural hematomas depends on the volume, moment of diagnosis, and neurological deficit level. Simultaneous drainage of bilateral hematomas has been demonstrated to be an effective technique for it, which soon decreases the intracranial pressure and promotes an efficient resolution to the neurological damage.

    Full Text Available Interatrial septal disorders, which include: atrial septal defect, patent foramen ovale and atrial septal aneurysm, are frequent congenital anomalies found in adult patients. Early detection of these anomalies is important to prevent their hemodynamic and/or thromboembolic consequences. The aims of this study were: to assess the association between impulse conduction disorders and anomalies of interatrial septum; to determine the prevalence of different types of interatrial septum abnormalities; to assess anatomic, hemodynamic, and clinical consequences of interatrial septal pathologies. Fifty-three adult patients with impulse conduction disorders and patients without ECG changes but with signs of interatrial septal abnormalities, who were referred to our center for echocardiography, were included in a prospective transesophageal echocardiography study. Intera trial septal anomalies were detected in around 85% of the examined patients.

    Objective To evaluate the ability of vector flow mapping (VFM) in visualizing right atrial flow and quantifying pulmonary to systemic flow ratio in patients with atrial septal defect (ASD). Methods VFM was performed on 30 patients with ASD and 50 healthy volunteers. The pulmonary to systemic flow ratio (Qp/Qs) was calculated using VFM and spectral doppler compared with that obtained through oximetric data derived from cardiac catheterization. Resnlts Blood streams from superior and inferior caval veins did not collide but turned forward, contributing to a forward clockwise vortex during systole on the subcostal bi-atrial plane in the healthy volunteers. The vortex was disrupted continuously by a left to right shunt in the patients with ASD during the hole cardiac cycle. The Qp/Qs measured by VFM was less angle-dependent in all the cases than the other methods. The mean value of Qp/Qs of the healthy volunteers calculated by apical three-chamber view and apical five-chamber view ranged from 0. 84 :1 to 1. 15 :1, which is consistent with the theoretical value 1 of no left to right shunts. The values of Qp/Qs of patients with ASD measured by VFM and spectral doppler showed no significant differences with those obtained through oximetric data C(2. 18±0. 48) vs. (2. 29±0. 76), P = 0. 29; (2.30±0. 91) vs. (2. 29± 0. 76), P=0. 863. However, the Qp/Qs value measured by VFM had a better correlation with the oximetric data than that measured by spectral doppler (r=0. 71, P<0. 001 vs. R=0. 38, P<0. 05). The inter-observer and intra-observer variability of Qp/Qs measured by VFM was 9. 84% and 9. 86% respectively. Conclusion VFM can visualize right atrial flow field in patients with ASD and quantify Qp/Qs in a more accurate way than spectral dopier.%目的 探讨血流向量成像(VFM)技术观察房间隔缺损(ASD)患者右房流场分布的可行性及定量肺、体循环血流量比(Qp/Qs)的准确性.方法 应用VFM观察50例健康体检者(正常组)和30例ASD患

There were 9 mitral replacements (7 bioprostetic and 2 mechanical and 6 repairs in GA, and 10 (all bioprostetic and five in GB. The mean aortic cross-clamp and cardiopulmonary bypass time, in minutes, were 65.1 ± 29.3 in GA and 50.2 ± 21.4 in GB (p=0.074; and 91.8±35 in GA and 63.7±27.3 in GB ( p=0.008. The mean ICU time, in hours, were 51.7 ± 16.3 in GA and 55.8±17.5 in GB (p=0.45. The in hospital stay, in days, were 5.2 ± 1 in GA and 6.4±1.5 in GB (p=0.009. CONCLUSION: MI access for correction of the MV disease and ASD implicated in a longer cardiopulmonary bypass time for finalization of the main procedure, nevertheless it didn´t affect patient's recuperation. MI treated patients were discharged earlier than sternotomy treated patients.

    2011-11-01

    Full Text Available Abstract Introduction The Amplatzer septal occluder is frequently used for percutaneous closure of an atrial septal defect. Complications include thrombosis and embolism, dislocation, cardiac perforation, and, rarely, infection. We report the case of a patient who had survived an occluder-related thromboembolism two years previously. Case presentation A 72-year-old Caucasian woman had received a septal occluder because of an atrial septal defect seven years ago. Two years ago, she underwent chemotherapy of a non-Hodgkin lymphoma, developed atrial fibrillation, and experienced a left-sided occluder thrombosis with stroke and peripheral embolism. Now, she presented with cerebral lymphoma, received glucocorticoids, and subsequently developed skin lesions. Swabs from the lesions and blood cultures were positive for methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa. Endocarditis, however, was considered only two months later and echocardiography suggested aortic valve endocarditis. Despite antibiotic therapy, she died three days later because of septicemia, and no post-mortem investigation was carried out. It remains uncertain whether the septal occluder was endothelialized or infected and whether explantation might have changed the outcome. Conclusions If infections occur in patients with a septal occluder, endocarditis should be considered and echocardiography should be performed early. To prevent a fatal outcome, explantation of the septal occluder should be considered, especially in patients with problems that suggest delayed endothelialization. Post-mortem investigations, including bacteriologic studies, should be carried out in patients with a septal occluder in order to assess the focal and global long-term effects of these devices.

    The purpose of this study was to investigate the characteristics of childhood acute epidural hematoma and to report our experience in recent years. A series of 35 patients below the age of 15 years treated for acute epidural hematoma at our institution between June 1991 and December 2000 was analyzed in detail. Pediatric epidural hematoma presents both age-related and atypical features when compared with epidural hematoma in adults. In selected cases, prompt surgical evacuation of the hematoma results in an excellent outcome. Outcomes seem to be directly related to the patient's preoperative neurologic status and the presence of associated intracranial lesions.

    Full Text Available Abstract Objective Correlate the anatomic features of atrioventricular septal defect with echocardiographic images. Materials and methods Sixty specimen hearts were studied by sequential segmental analysis. Echocardiograms were performed on 34 patients. Specimen hearts with findings equivalent to those of echocardiographic images were selected in order to establish an anatomo-echocardiographic correlation. Results Thirty-three specimen hearts were in situs solitus, 19 showed dextroisomerism, 6 were in situs inversus and 2 levoisomerism. Fifty-eight had a common atrioventricular valve and 2 had two atrioventricular valves. Rastelli types were determined in 21 hearts. Nine were type A, 2 intermediate between A and B, 1 mixed between A and B, 4 type B and 5 type C. Associated anomalies included pulmonary stenosis, pulmonary atresia atrial septal defect, patent ductus arteriosus and anomalous connection of pulmonary veins. Echocardiograms revealed dextroisomerism in 12 patients, situs solitus in 11, levoisomerism in 7 and situs inversus in 4. Thirty-one patients had common atrioventricular valves and three two atrioventricular valves. Rastelli types were established in all cases with common atrioventricular valves; 17 had type A canal defects, 10 type B, 3 intermediate between A and B, 1 mixed between A and B and 3 type C. Associated anomalies included regurgitation of the atrioventricular valve, pulmonary stenosis, anomalous connection of pulmonary veins, pulmonary hypertension and pulmonary atresia. Conclusion Anatomo-echocardiographic correlation demonstrated a high degree of diagnostic precision with echocardiography.

Se presenta un paciente de 75 años sin antecedentes remarcables, con cuadro de disnea de 7 días de evolución. La radiografía y tomografía de tórax mostraron una elevación del hemidiafragma derecho (confirmándose su parálisis por radioscopia sin alteraciones en el parénquima pulmonar y mediastino. El ecocardiograma contrastado evidenció un foramen oval permeable y un aneurisma del septum interauricular. La angiografía pulmonar descartó tromboembolismo o malformación vascular y las presiones en la arteria pulmonar fueron normales, sin evidencia de shunt. Al momento de ambos estudios, realizados en decúbito supino, el paciente no tenía síntomas. En la evolución, la disnea también se manifestó en esa postura y el paciente espontáneamente adoptó el decúbito lateral derecho donde la oxemia era normal. Se realizó un ecocardiograma transesofágico contrastado que mostró un shunt derecha-izquierda intracardíaco y se colocó un dispositivo de Alplatzer para el cierre de la comunicación interauricular. Los gases arteriales post-procedimiento fueron normales.

    Full Text Available Vinodan Paramanathan, Ardalan ZolnourianQueen's Hospital NHS Foundation Trust, Burton on Trent, Staffordshire DE13 0RB, UKAbstract: Spontaneous intraorbital hematoma is an uncommon clinical entity seen in ophthalmology practice. It is poorly represented in the literature. Current evidence attributes it to orbital trauma, neoplasm, vascular malformations, acute sinusitis, and systemic abnormalities. A 65-year-old female presented with spontaneous intraorbital hematoma manifesting as severe ocular pains, eyelid edema, proptosis, and diplopia, without a history of trauma. Computer tomography demonstrated a fairly well defined extraconal lesion with opacification of the paranasal sinuses. The principal differential based on all findings was that of a spreading sinus infection and an extraconal tumor. An unprecedented finding of a spontaneous orbital hematoma was discovered when the patient was taken to theater. We discuss the rarity of this condition and its management.Keywords: hemorrhage, ophthalmology, spontaneous, intra-orbital, hematoma

    2014-12-01

    Transcatheter device closure of atrial septal defects (ASDs) is a minimally invasive technique that offers an alternative to conventional surgical repair. There are risks imposed by this technique; however, they compare favourably with risks of surgical closure. Here, we present a case of a 59-year old male with late erosion of an Amplatzer septal occluder device resulting in cardiac tamponade 5 years after device placement. To the best of our knowledge, cardiac tamponade this late after device placement has not yet been reported. Septal occlusion device erosion remains a major issue among the risks imposed by device closure of an ASD. More data are needed to better understand its true causes and possible solutions.

    Full Text Available A 34-year-old female presented with sudden onset of severe abdominal pain in a flank distribution. A large mass was palpable in the right upper quadrant on physical examination. Abdominal contrast-enhanced computed tomography showed a well-defined, right-sided, retroperitoneal cystic lesion located between the abdominal aorta and the inferior vena cava (IVC. The tumor size was 55 × 58 mm, and it compressed the gallbladder and the duodenum. Upper gastrointestinal radiography revealed a stricture of the second portion of the duodenum by the tumor. T2-weighted magnetic resonance imaging showed that the whole part was hyperintense with hypointense rims, but the inner was partially hypointense. Based on the radiological findings, the preoperative differential diagnosis included retroperitoneal teratoma, Schwannoma, abscess, and primary retroperitoneal tumor. On laparotomy, the tumor was located in the right retroperitoneal cavity. Kocher maneuver and medial visceral rotation, which consists of medial reflection of the upper part of right colon and duodenum by incising their lateral peritoneal attachments, were performed. Although a slight adhesion to the IVC was detected, the tumor was removed safely. Thin-section histopathology examination detected neither tumor tissues nor any tissues such as adrenal gland, ovarian tissue, or endometrial implants. The final pathological diagnosis was idiopathic retroperitoneal hematoma; the origin of the bleeding was unclear. The patient was discharged without any complication 5 days after the operation.

    Background/Aims The aim of this study was to investigate atrial conduction times and left atrial mechanical functions, the noninvasive predictors of atrial fibrillation, in prediabetic patients with impaired fasting glucose (IFG) and impaired glucose tolerance (IGT). Methods Study included 59 patients (23 males, 36 females; mean age 52.5 ± 10.6 years) diagnosed with IFG or IGT by the American Diabetes Association criteria, and 43 healthy adults (22 males, 21 females; mean age 48.5 ± 12.1 years). Conventional and tissue Doppler echocardiography were performed. The electromechanical delay parameters were measured from the onset of the P wave on the surface electrocardiogram to the onset of the atrial systolic wave on tissue Doppler imaging from septum, lateral, and right ventricular annuli. The left atrial volumes were calculated by the disk method. Left atrial mechanical functions were calculated. Results The mitral E/A and E’/A’ ratios measured from the lateral and septal annuli were significantly lower in the prediabetics compared to the controls. The interatrial and left atrial electromechanical delay were significantly longer in prediabetic group compared to the controls. Left atrial active emptying volume (LAAEV) and fraction (LAAEF) were significantly higher in the prediabetics than the controls. LAAEV and LAAEF were significantly correlated with E/A, lateral and septal E’/A’. Conclusions In the prediabetic patients, the atrial conduction times and P wave dispersion on surface electrocardiographic were longer before the development of overt diabetes. In addition, the left atrial mechanical functions were impaired secondary to a deterioration in the diastolic functions in the prediabetic patients. PMID:27919159

    We present the first report of an intraventricular encapsulated hematoma, mimicking cavernous malformation on imaging and gross lesion appearance. A 47-year-old female on anticoagulation therapy for atrial fibrillation presented with left upper extremity apraxia, neglect, and mild gait imbalance. Her brain CT scan and MRI revealed multilobulated lesions involving the choroid plexus in the atria of both lateral ventricles. The intraoperative appearance was that of encapsulated mass, with blood clots at different stages of liquefaction and organization, all consistent with the gross appearance of a cavernous malformation. However, histopathologic examination demonstrated hematoma with components at different ages, and normal vessel infiltration without any hint of cavernous malformation histology, or underlying neoplasia. Encapsulated hematoma should be considered in the differential diagnosis of hemorrhagic intraventricular masses. PMID:21435884

    Full Text Available To pack or not to pack, has always been a debate, especially after septal and functional endoscopic sinus surgery. The authors have studied the symptoms of packing versus not packing in their series of 100 patients having undergone nasal surgery. They advocate the use of dental wax for the fashioning of septal splints, since they are easy to introduce, cheap and malleable. The patients postoperative comfort is greatly enhanced with the use of dental wax plate splints instead of nasal packing.

  3. Mozart's chronic subdural hematoma.

    1993-11-01

    No commemoration of the bicentennial of Mozart's death would be complete without some consideration of that premature yet predictable demise. Mozart's premonitions of death are well known and apparently played a role in the composition of the K.626 Requiem and perhaps other works. His death has traditionally been ascribed to infectious causes, chiefly rheumatic fever or post-streptococcal glomerulonephritis, exacerbated by intemperance and chronic penury. Pathology has been difficult because of his supposed burial in a pauper's grave, the location and contents of which were later supposedly lost. Mozart's burial place in St. Mark's Cemetery in Vienna was known and, in the parlance of the day, "reorganized" a decade later, as the occupants of plots were disinterred to make room for the more recently decreased. A skull believed to the Mozart's was saved by the successor of the gravedigger who had supervised Mozart's burial, and then passed into the collections of the anatomist Josef Hyrtl, the municipality of Salzburg, and the Mozarteum museum (Salzburg). Forensic reconstruction of soft tissues related to this skull reveals substantial concordance with Mozart's portraits. The skull suggests premature closure of the metopic suture, which has been suggested on the basis of his physiognomy. A left temporal fracture and concomitant erosions raise the question of chronic subdural hematoma, which would be consistent with several falls in 1789 and 1790 and could have caused the weakness, headaches, and fainting he experienced in 1790 and 1791. Aggressive bloodletting to treat suspected rheumatic fever could have decompensated such a lesion to produce his death on December 5, 1791.

    Full Text Available Background. Posterior fossa epidural hematomas represent 7-14% of all traumatic intracranial epidural hematomas. They are most frequently encountered posttraumatic mass lesions in the posterior fossa. The aim of this study was to identify clinical features that could lead to the early diagnosis of posterior fossa epidural hematoma. Methods. Between 1980 and 2002, 28 patients with epidural hematoma of the posterior fossa were operated on at the Institute for Neurosurgery, Belgrade. Clinical course neuroradiological investigations, and the results of surgical treatment of the patients with posterior fossa epidural hematomas were analyzed retrospectively. Results. Almost two thirds of patients were younger than 16 years of age. In 20 cases injury was caused by a fall, in 6 cases by a traffic accident, and in 2 by the assault. Clinical course was subacute or chronic in two thirds of the patients. On the admission Glasgow Coma Scale was 7 or less in 9 injured, 8-14 in 14 injured, and 15 in 5 injured patients. Linear fracture of the occipital bone was radiographically evident in 19 patients, but was intraoperatively encountered in all the patients except for a 4-year old child. In 25 patients the diagnosis was established by computer assisted tomography (CAT and in 3 by vertebral angiography. All the patients were operated on via suboccipital craniotomy. Four injured patients who were preoperatively comatose were with lethal outcome. Postoperatively, 24 patients were with sufficient neurologic recovery. Conclusion. Posterior fossa epidural hematoma should be suspected in cases of occipital injury, consciousness disturbances, and occipital bone fracture. In such cases urgent CAT-scan is recommended. Early recognition early diagnosis, and prompt treatment are crucial for good neurological recovery after surgery.

    2000-01-01

    @@INTRODUCTION Esophageal hematomas develop from the dissection of the mucosa from the muscular layers of the esophageal wall and represent an uncommon condition affecting all ages[t-3]. Although the most common cause of esophageal hematomas is iatrogenic mechanical injury-induced by prolonged nasogastric intubation, difficult or forceful endoscopic intubation, or the result of variceal injection sclerotherapy- some may be spontaneous,particularly in patients receiving anticoagulants[3-6]. Presenting symptoms most commonly include dysphagia, hematemesis, and sub-sternal or epigastric pain[5,9].

    2004-01-01

    Objective:To investigate the clinical characteristics of intracranial hematoma and the mechanism involved in its rapid natural resolution. Methods:Seventeen cases of intracranial hematoma with typical clinical and CT manifestations were retrospectively studied. Results: Intracranial hematoma was found obviously decreased in size within 72 h after its occurrence in 8 cases. The rest 9 cases presented complete resolution. Conclusions: Rapid natural resolution of acute epidural hematoma is mostly found in teenagers and the resolution is correlated with cranial fracture at the hematoma site. As for acute subdural hematoma, its rapid resolution is associated with the transfer of cerebrospinal fluid toward subdural space, the lavage effect, and the compression caused by the increased intracranial pressure or the space left resulting from redistribution of the hematoma in brain atrophy.

  11. Is human fracture hematoma inherently angiogenic?

    LENUS (Irish Health Repository)

    Street, J

    2012-02-03

    This study attempts to explain the cellular events characterizing the changes seen in the medullary callus adjacent to the interfragmentary hematoma during the early stages of fracture healing. It also shows that human fracture hematoma contains the angiogenic cytokine vascular endothelial growth factor and has the inherent capability to induce angiogenesis and thus promote revascularization during bone repair. Patients undergoing emergency surgery for isolated bony injury were studied. Raised circulating levels of vascular endothelial growth factor were seen in all injured patients, whereas the fracture hematoma contained significantly higher levels of vascular endothelial growth factor than did plasma from these injured patients. However, incubation of endothelial cells in fracture hematoma supernatant significantly inhibited the in vitro angiogenic parameters of endothelial cell proliferation and microtubule formation. These phenomena are dependent on a local biochemical milieu that does not support cytokinesis. The hematoma potassium concentration is cytotoxic to endothelial cells and osteoblasts. Subcutaneous transplantation of the fracture hematoma into a murine wound model resulted in new blood vessel formation after hematoma resorption. This angiogenic effect is mediated by the significant concentrations of vascular endothelial growth factor found in the hematoma. This study identifies an angiogenic cytokine involved in human fracture healing and shows that fracture hematoma is inherently angiogenic. The differences between the in vitro and in vivo findings may explain the phenomenon of interfragmentary hematoma organization and resorption that precedes fracture revascularization.

    Full Text Available Introduction: Extradural hematomas (EDHs accounts for approximately 2% of patients following head trauma and 5-15% of patients with fatal head injuries. When indicated, the standard surgical management consists of evacuation of the hematoma via craniotomy. Intraoperative development of acute extradural hematoma (AEDH on the contralateral side following evacuation of acute extradural hematoma is uncommon and very few cases have been reported.

    Rho/Rho-kinase pathway plays a critical role in the regulation of cellular functions such as proliferation and migration. One of the possible theories of the development of ventricular septal defects is cell migration disorder. The aim of this study was to analyze the genotype distributions and allele frequencies for the ROCK2 gene Thr431Asn polymorphisms in the development of cardiac septal defects in a Turkish population. In this case-control study, 300 patients with cardiac defects (150 patients with ventricular and 150 patients with atrial septal defects) and control group (150 healthy control subjects) were investigated. A single-nucleotide polymorphism in ROCK2 gene Thr431Asn was analyzed by real-time PCR using a Light-Cycler. Neither genotype distributions nor the allele frequencies for the Thr431Asn polymorphism showed a significant difference between the groups. These results suggest that there is no association of the ROCK2 gene Thr431Asn polymorphism with the development of cardiac septal defects in pediatric patients.

    Full Text Available Rectus Sheath Hematoma (RSH represents an unusual entity which is characterized by acute abdominal pain and tender palpable abdominal mass usually, among elderly patients receiving anticoagulant therapy. We report the case of an 81-year-old woman admitted to our department due to acute abdominal pain and oligoanuria. The patient had recently been hospitalized due to acute myocardial infarction (AMI and atrial fibrillation (AF and received both anticoagulant and antiplatelet therapies. The radiological assessments revealed an extended Rectus Sheath Hematoma and bilateral hydronephrosis. Treatment of the hematoma required cessation of anticoagulants and antiplatelet agents, immobilization, blood and fresh frozen plasma transfusion, and administration of vasopressors. The patient recovered gradually and was discharged home fifteen (15 days later.

    Full Text Available Spontaneous sublingual hematoma and intramural small bowel hematoma are rare and serious complications of anticoagulant therapy. Though previously reported individually, there has been no previous report of the same two complications occurring in a single patient. A 71-year-old Caucasian man, who was on warfarin for atrial fibrillation, presented with difficulty in swallowing due to a sublingual hematoma. He was observed in our intensive care unit, his warfarin was held and he recovered with conservative management. He represented two months later with a two day history of abdominal pain and distension. An abdominopelvic computed tomography (CT scan now showed small bowel obstruction due to intramural small bowel hematoma and haemorrhagic ascites. Again, this was treated expectantly with a good outcome. In conclusion, life threatening haemorrhagic complications of oral anticoagulant therapy can recur. Conservative treatment is successful in most cases, but an accurate diagnosis is mandatory to avoid unnecessary surgery. CT scan is the investigation of choice for the diagnosis of suspected haemorrhagic complications of over coagulation.

Associated cardiac anomalies included patent ductus arteriosus (9, aortic coarctation (2, hypoplastic aortic arch (2 and left isomerism (1. Five patients (5/17 =29.4% required pre-operative mechanical ventilation, with a mean duration of 64 days (7 to 240 daysRESULTSThere were no early or late deaths during a mean follow-up of 48 months (7 to 98 months, with either FloWatch removal or last observation as end-points.FloWatch-PAB adjustments were required in all patients: a mean of 4.8 times/patient (2 to 9 to tighten the PAB, and a mean of 1.1 times/patient (0 to 3 to release the PAB with the patient’s growth. After a mean interval of 29 months (8 to 69 months 10/17 (59% patients underwent reoperation: 7/10 PAB removal, with closure of a remaining peri-membranous VSD in 6 and Damus-Kaye-Stansel, bi-directional Glenn, and atrial septectomy in 1; 3/9 patients required only PAB removal. All muscular multiple VSDs had closed in all 10 patients. PA reconstruction was required in 1/10 patient. In 5/7 of the remaining patients with the PAB still in situ, all muscular VSDs had already closed. The only 2 patients with persistent muscular multiple VSDs are the 2 patients with the shortest follow-up.CONCLUSIONS This reproducible new strategy with an adjustable PAB simplifies the management of infants with multiple VSDs and provides the following advantages: a good results (0% mortality, delayed surgery with a high incidence (15/17=88% of spontaneous closure of multiple muscular VSDs, and facilitated closure of residual peri-membranous VSD at an older age and h

    Full Text Available Background: Balloon atrial septostomy is an emergent procedure in pediatric cardiology. Nowadays, most patients in need of the procedure have acceptable outcomes after surgical repair. Thus, it is important to perform this procedure as safe as possible. By performing early arterial switch operation and prostaglandin infusion, the rate of balloon atrial septostomy has markedly decreased. However, not all centers performing early arterial switch repairs have abandoned atrial septostomy, even in patients who respond favorably to prostaglandin infusion.Case presentation: In total, eight 1- to 15-day old term neonates admitted in Shahid Rajaee Heart Center in Tehran, Iran from October 2009 to February 2011, with congenital heart diseases were scheduled for balloon atrial septostomy. In six cases the procedure was done exclusively under echocardiographic guidance and in two cases with the help of fluoroscopy. Success was defined as the creation of an atrial septal defect with a diameter equal to or more than 5 mm and ample mobility of its margins.Results: Male sex was predominant (87% and the mean age of the neonates was six days. The diagnosis in all cases was simple transposition of great arteries. The procedure was successful in all patients with any cardiovascular complication.Conclusion: Balloon atrial septostomy is an emergent procedure that can be done safely and effectively under echocardiographic guidance. According to the feasibility of this technique it could be performed fast, safe and effective at bedside, avoiding patient transportation to hemodynamic laboratory or referral center.

    2017-01-01

    Background Bleeding from bypass anastomosis leakage occurs early after coronary artery bypass grafting. Later, once the anastomosis is covered by intima, spontaneous bleeding is unlikely. Case Description A 63-year-old male patient developed a pseudoaneurysm-like, subepicardial late-term bleeding resulting in a hematoma that compromised coronary artery flow by increasing extracoronary pressure. This resulted in severe angina pectoris (Canadian Cardiovascular Society IV) and myocardial ischemia within the affected area. After surgical removal of the hematoma and repair of the anastomosis, the patient's symptoms disappeared and no signs of myocardial ischemia were present. Conclusion Surgical removal is an efficient therapy for subepicardial hematoma inducing myocardial ischemia.

    2006-11-01

    A combined septal perforation repair and rhinoplasty was performed in 80 patients presenting with septal perforations (size 1 to 5 cm) and external nasal deformities. The external rhinoplasty approach was used for all cases and the perforation was repaired using bilateral intranasal mucosal advancement flaps with a connective tissue interposition graft in between. Complete closure of the perforation was achieved in 90% of perforations of size up to 3.5 cm and in only 70% of perforations that were larger than 3.5 cm. Cosmetically, 95% were very satisfied with their aesthetic result. The external rhinoplasty approach proved to be very helpful in the process of septal perforation repair especially in large and posteriorly located perforations and in cases where the caudal septal cartilage was previously resected. Our results show that septal perforation repair can be safely combined with rhinoplasty and that some of the routine rhinoplasty maneuvers, such as medial osteotomies and dorsal lowering, could even facilitate the process of septal perforation repair.

    Study Design Case report. Objective To report the first case of ligamentum flavum hematoma after cervical spine instrumentation 11 years after the index surgery. Methods After performing bilateral C3 and C4 laminectomy, we observed a dark greenish discoloration over the ligamentum flavum, which was opened. We evacuated 15 mL of subacute hematoma. Results The first ligamentum flavum hematoma of the cervical spine that occurred after spinal instrumentation with sublaminar hooks. Conclusion Ligamentum flavum hematoma might happen even after a long delay (in our case, 11 years) from spinal instrumentation (sublaminar hooks). In symptomatic patients, evacuation is the treatment of choice. In cases of instrument adhesion to the surrounding intracanal tissues, removal should be done meticulously after performing a complete release.

    Full Text Available OBJECTIVE: Analyze the dromotropic disturbances (vector-electrocardiographic, and the possible anatomic causes, provoked by selective alcohol injection in the septal branch, for percutaneous treatment, of obstructive hypertrophic cardiomyopathy. METHODS: Ten patients with a mean age of 52.7 years underwent percutaneous septal ablation (PTSA from october 1998; all in functional class III/IV. Twelve-lead electrocardiogram was performed prior to and during PTSA, and later electrocardiogram and vectorcardiogram according to Frank's method. The patients were followed up for 32 months. RESULTS: On electrocardiogram (ECG prior to PTSA all patients had sinus rhythm and left atrial enlargement, 8 left ventricular hypertrophy of systolic pattern. On ECG immediately after PTSA, 8 had complete right bundle-branch block; 1 transient total atrioventricular block; 1 alternating transient bundle-branch block either right or hemiblock. On late ECG 8 had complete right bundle-branch block confirmed by vectorcardiogram, type 1 or Grishman. CONCLUSION: Septal fibrosis following alcohol injection caused a predominance of complete right bundle-branch block, different from surgery of myotomy/myectomy.

    The aim of this study was to evaluate atrial electromechanical delay (EMD), P wave dispersion (Pwd), and left atrial (LA) mechanical functions in patients with active acromegaly. Twenty-three patients with active acromegaly and 27 age- and sex-matched controls were included in this study. All atrial electromechanical interval parameters (PA lateral, PA septum, PA tricuspid, interatrial EMD, intra-LA EMD, and intra-right atrial EMD) were measured from mitral lateral annulus, mitral septal annulus, and right ventricular tricuspid annulus by tissue Doppler imaging. LA volumes were measured by the disk method in the apical four-chamber view and were indexed to the body surface area. Mechanical function parameters of LA were calculated. Pwd was performed by 12-lead electrocardiograms. Atrial electromechanical intervals (PA lateral, PA septum, PA tricuspid, interatrial EMD, intra-LA EMD, and intra-right atrial EMD) and Pwd were similar between patients with acromegaly and control subjects (all p > 0.05). LA volumes (maximum, minimum, and presystolic) and LA mechanical functions were not significantly different between the groups (all p > 0.05). Additionally, serum levels of growth hormone and insulin-like growth factor-1 were not correlated with atrial electromechanical parameters and LA mechanical functions. Atrial electrical conduction times were not prolonged and LA mechanical functions were not impaired in patients with active acromegaly compared with controls. And the prevalence of supraventricular arrhythmia risk may not increase in this population.

    Full Text Available In paroxysmal atrial fibrillation usually pulmonary veins isolation is enough, while in persistent and long-standing persistent forms ablation lines in the left atrium are needed. After that post ablational macroreentry tachycardia and focal atrial tachycardia, resistant to antiarrhythmic therapy, occur. Left atrial macroreentry tachycardia are localized perimitrally, around pulmonary veins and septally. There are also roof and posterior wall-associated macroreentry tachycardia. Considering relevance of postablation arrhythmias, we present our case report. A patient had paroxysmal atrial fibrillation. Pulmonary vein isolation was performed. After patient’s radiofrequency pulmonary vein isolation, three-dimensional map of left atrium was made using CARTO XP navigation system. Macroreentry tachycardia around left inferior pulmonary vein was revealed.There were fragmented potentials between left superior and left inferior pulmonary veins. An ablation lineconnecting inferior and superior pulmonary veins was made. After the completion of ablation line sinus rhythmwas restored.

    Full Text Available We describe presence of an unusual right atrial membrane in a 30-year old female with end stage renal disease, hypertension and peripheral vascular disease. The patient was scheduled for midline sternotomy and pericardiotomy and removal of a migrated vascular stent in the right pulmonary artery. An intraoperative transesophageal echocardiogram (TEE revealed an unusual membranous structure with fenestrations that stretched across the right atrium with attachments superiorly at the free wall and inferiorly at the inter-atrial septum. There was no evidence of flow obstruction across the tricuspid valve. Some of the considerations for the likely diagnosis of this structure were a prominent Eustachian valve, persistent Chiari network, aneurysmal inter-atrial septum, an inter-atrial septal cyst or Cor triatriatum dexter (CTD.

  17. Atrial fibrillation.

    Atrial fibrillation (AF) is a common complication after myocardial infarction (MI) and new-onset AF has been demonstrated to be associated with adverse outcome and a large excess risk of death in both MI and aortic stenosis (AS) patients. Prevention of new-onset AF is therefore a potential therapeutic target in AS and MI patients. Lipid-lowering drugs, particularly statins, have anti-inflammatory and antioxidant properties that may prevent AF. Accordingly, statins are recommended as a class IIa recommendation for prevention of new-onset AF after coronary artery bypass grafting (CABG). However, this preventive effect has not been investigated on new-onset AF in asymptomatic patients with AS or a large scale first-time MI patient sample and data in patients not undergoing invasive cardiac interventions are limited. This PhD thesis was conducted at the Heart Centre, Rigshospitalet, Denmark, with the aim to investigate the three aforementioned questions and to add to the existing evidence of AF prevention with statins. This was done using three different settings: 1) a randomized patients sample of 1,873 from the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) study, 2) a register patient sample of 97,499 with first-time MI, and 3) all published studies until beginning of June 2011 examining statin treatment on new-onset and recurrent AF in patients not undergoing cardiac surgery. This thesis revealed that statins did not lower the incidence or the time to new-onset AF in patients with asymptomatic AS. However, statin treatment showed an independently preventive effect on new-onset AF, including type-dependent effect and a trend to dosage-dependent effect. In addition, this thesis showed that good compliance to statin treatment was important to prevent new-onset AF. Finally, the meta-analysis in this PhD thesis showed a preventive effect in the observational studies although this effect was absent in the randomized controlled trials. Based on this PhD thesis

    2014-01-01

    Full Text Available Atrial fibrillation (AF is an independent risk factor for stroke. Anticoagulation therapy has a risk of intracerebral hemorrhage. The use of percutaneous left atrial appendage (LAA closure devices is an alternative to anticoagulation therapy. Echocardiography has a leading role in LAA closure procedure in patient selection, during the procedure and during followup. A comprehensive echocardiography study is necessary preprocedural in order to identify all the lobes of the LAA, evaluate the size of the LAA ostium, look for thrombus or spontaneous echo contrast, and evaluate atrial anatomy, including atrial septal defect and patent foramen ovale. Echocardiography is used to identify potential cardiac sources of embolism, such as atrial septal aneurysm, mitral valve disease, and aortic debris. During the LAA occlusion procedure transeosophageal echocardiography provides guidance for the transeptal puncture and monitoring during the release of the closure device. Procedure-related complications can be evaluated and acceptable device release criteria such as proper position and seating of the occluder in the LAA, compression, and stability can be assessed. Postprocedural echocardiography is used for followup to assess the closure of the LAA ostium. This overview paper describes the emerging role of LAA occlusion procedure with transeosophageal echocardiography guidance as an alternative to anticoagulation therapy in patients with AF.

    Spinal epidural hematoma is an accumulation of blood in the potential space between the dura and bone. On unenhanced computed tomography epidural hemorrhage appears as a high-density spinal canal mass with variable cord compression. Magnetic resonance imaging is the modality of choice for evaluating spinal epidural hematoma and can demonstrate the extent of the hematoma and degree of cord compression. When treated surgically the outcome depends on the extent of preoperative neurological deficits and on the operative timing interval. (orig.) [German] Das spinale epidurale Haematom ist eine Blutansammlung zwischen Dura und Knochen. Die klinische Praesentation ist aehnlich dem akuten Bandscheibenvorfall, die Symptomatik ist allerdings in der Regel progredient. In der CT stellt sich ein frisches Haematom hyperdens dar. Die MRT ist die Methode der Wahl zur Diagnose spinaler epiduraler Haematome und kann die Ausdehnung sowie auch das Ausmass der Kompression darstellen. Die wichtigste Differenzialdiagnose vom epiduralen Haematom ist das epidurale Empyem. (orig.)

    Full Text Available An 8-month-old male infant had presented with a history of a fall from the crib a fortnight ago. He had developed progressive weakness of both lower limbs. On examination, the infant had spastic paraplegia. Magnetic resonance (MR imaging of the cervical spine showed an epidural hematoma extending from the fourth cervical (C4 to the first dorsal (D1 vertebral level with cord compression. The patient had no bleeding disorder on investigation. He underwent cervical laminoplasty at C6 and C7 levels. The epidural hematoma was evacuated. The cervical cord started pulsating immediately. Postoperatively, the patient′s paraplegia improved dramatically in 48 hours. According to the author′s literature search, only seven cases of post-traumatic epidural hematoma have been reported in pediatric patients, and our patient is the youngest. The present case report discusses the etiopathology, presentation, and management of this rare case.

    Full Text Available Background. Traumatic delayed epidural hematoma (DEH can be defined as insignificant or not seen on the initial CT scan performed after a trauma but seen on the subsequent CT scan as a “massive” epidural bleeding. Case report. We presented two cases of traumatic DEH after mild head injury. Both patients were conscious and without neurological deficit on the admission. Initial CT scan did not reveal intracranial hematoma. Repeated CT scan, that was performed after neurological deterioration, revealed epidural hematoma in both cases. The patients were operated with a favorable surgical outcome. Conclusion. Traumatic DEH could occur in the patients with head injuries who were conscious on the admission with a normal initial CT scan finding. Early detection of DEH and an urgent surgical evacuation were essential for a good outcome.

    We report a case of subcorneal hematomas caused by excessive video game play in a 19-year-old man. The hematomas occurred in a setting of thrombocytopenia secondary to induction chemotherapy for acute myeloid leukemia. It was concluded that thrombocytopenia subsequent to prior friction from heavy use of a video game controller allowed for traumatic subcorneal hemorrhage of the hands. Using our case as a springboard, we summarize other reports with video game associated pathologies in the medical literature. Overall, cognizance of the popularity of video games and related pathologies can be an asset for dermatologists who evaluate pediatric patients.

    Postoperative epidural hematomas developed far from the operative field are generally recognized as a complication of ventriculo-peritoneal shunt, ventricular drainage or suboccipital craniotomy. It is very rare but may occur after supratentorial craniotomy on the contralateral side. Five such cases are presented with a review of the relevant literature. The mechanism of this complication is not clearly understood. In hydrocephalus, these massive epidural hematomas are probably caused by dura-skull detachment when the brain volume is strikingly reduced by a decompressive procedure. On rare occasions, pins of head rest may detach the dura and cause epidural hematomas. When sudden brain swelling during craniotomy is encountered, attention should be directed not only to intracerebral hemorrhage but also epidural hematoma developed on the contralateral side.

    Full Text Available Traumatic acute subdural hematoma (ASDH is generally addressed by craniotomy under general anesthesia. We report a patient whose traumatic ASDH was treated under local anesthesia by one-burr-hole endoscopic surgery. This 87-year-old woman had undergone coil embolization for a ruptured right middle-cerebral artery aneurysm and placement of a ventriculoperitoneal shunt for normal pressure hydrocephalus 5 years earlier. Upon admission, she manifested consciousness disturbance after suffering head trauma and right hemiplegia. Her Glasgow Coma Scale score was 8 (E2V2M4. Computed tomography (CT demonstrated a thick, left-frontotemporal ASDH. Due to her advanced age and poor condition, we performed endoscopic surgery rather than craniotomy to evacuate the ASDH. Under local anesthesia, we made a burr hole in her left forehead and increased its size to 15 mm in diameter. After introducing a transparent sheath into the hematoma cavity with a rigid endoscope, the clot was evacuated with a suction tube. The arterial bleeding point was electrically coagulated. A postoperative CT scan confirmed the reduction of the hematoma. There was neither brain compression nor brain swelling. Her consciousness disturbance and right hemiplegia improved immediately. Endoscopic surgery may represent a viable method to address traumatic intracranial hematomas in some patients.

    Full Text Available Introdução: Entre as complicações da septoplastia, o sangramento e o hematoma septal pós-operatório estão entre as mais freqüentes1,2,3. Para prevenir tais problemas, a maioria dos cirurgiões ainda faz uso de tamponamentos nasais ou "splints", que tornam o período pós-operatório imediato extremamente desconfortável para o paciente1,2,4,5,6. Este trabalho se propõe a avaliar a eficácia e a segurança do uso da cola biológica nas septoplastias como profilaxia para essas complicações. Forma de estudo: Clínico prospectivo randomizado. Material e método: Os autores observaram 20 pacientes operados de septoplastia entre janeiro e maio de 2002 pelo Real Instituto de Otorrino e Fono, Recife, nos quais foi utilizado selante de fibrina para colar os folhetos septais. Resultados: Nenhum caso de hematoma septal ou epistaxe pós-operatórios foi observado entre os pacientes estudados. Nenhuma complicação intra ou pós-operatória foi relacionada ao uso da cola. Conclusões: A cola de fibrina mostrou ser uma substância eficaz na prevenção das complicações em questão, assim como bem tolerada pelos tecidos das cavidades nasais. Além disso, o recurso assegurou um pós-operatório muito mais tranqüilo e confortável para os pacientes do que o que se costuma observar em pacientes com tampões nasais ou "splints".Introduction: Among the complications of septoplaty, postoperative septal bleeding and hematoma are some of the most frequent.

    Two cases are described in which severe mechanical hemolytic anemia developed after surgical repair of primum atrial septal defect (ASD) and cleft mitral valve. In both cases there was residual mitral regurgitation after repair. Moderate mitral regurgitation and collision of the regurgitant jet with the teflon patch used for repair of the primum ASD were detected by color-Doppler echocardiography imaging. Laboratory tests showed normochromic normocytic anemia, increased indirect serum bilirubin, decreased plasma haptoglobin and hemoglobinuria. The peripheral blood smear contained numerous fragmented red cells. Following another surgical correction of the mitral valve (repair or mitral valve replacement), there was no more hemolysis. The two presented cases show that foreign materials in association with localized intracardiac turbulence may cause severe hemolysis.

    Conclusions: LV diastolic dysfunction becomes more severe in septal wall than lateral wall in hypertensive LVH. Septal myocardial performance is more dominantly affected by hypertension possibly due to earlier septal involvement in disease course. Septal MPI is correlated moderately with septal wall thickness.

    Atrial fibrillation is the most common cardiac arrhythmia, and its treatment options include drug therapy or catheter-based or surgical interventions. The surgical treatment of atrial fibrillation has undergone multiple evolutions over the last several decades. The Cox-Maze procedure went on to become the gold standard for the surgical treatment of atrial fibrillation and is currently in its fourth iteration (Cox-Maze IV). This article reviews the indications and preoperative planning for performing a Cox-Maze IV procedure. This article also reviews the literature describing the surgical results for both approaches including comparisons of the Cox-Maze IV to the previous cut-and-sew method.

    2010-09-01

    Only a few cases of nontraumatic orbital subperiosteal hematoma due to scuba diving have been reported, and this is the first of such cases that underwent surgical intervention. This injury results from negative pressure within the face mask, suctioning orbital tissues into the mask after incomplete equilibration of pressure on descent. Valsalva maneuver is a second mechanism implicated in the etiology of this injury. Recognition of this injury is of the utmost importance because vision loss is a possible complication if there is compression of the optic nerve or increased intraocular pressure. In many cases of nontraumatic orbital hematoma, conservative management is adequate; however, this case was an exception due to worsening exam findings. Divers may be able to prevent this injury by frequent and gentle equilibration of mask pressure on descent.

    Full Text Available OBJECTIVE: To study mitral valve function in the postoperative period after correction of the partial form of atrioventricular septal defect. METHODS: Fifty patients underwent surgical correction of the partial form of atrioventricular septal defect. Their mean age was 11.8 years and 62% of the patients were males. Preoperative echocardiography showed moderate and severe mitral insufficiency in 44% of the patients. The mitral valve cleft was sutured in 45 (90% patients (group II - GII. Echocardiographies were performed in the early postoperative period, and 6 and 12 months after hospital discharge. RESULTS: The patients who had some type of arrhythmia in the postoperative period had ostium primum atrial septal defect of a larger size (2.74 x 2.08 cm. All 5 patients in group I (GI, who did not undergo closure of the cleft, had a competent mitral valve or mild mitral insufficiency in the preoperative period. One of these patients began to have moderate mitral insufficiency in the postoperative period. On the other hand, in GII, 88.8% and 82.2% of the patients had competent mitral valve or mild mitral insufficiency in the early and late postoperative periods, respectively. CONCLUSION: The mitral valve cleft was repaired in 90% of cases. Echocardiography revealed competent mitral valve or mild mitral insufficiency in 88.8% and 82.2% of GII patients in the early and late postoperative periods, respectively.

    Full Text Available Objectives: Hypertrophic cardiomyopathy (HCM represents a generalized myopathic process affecting both ventricular and atrial myocardium. We assessed the global and regional left atrial (LA function and its relation to left ventricular (LV mechanics and clinical status in patients with HCM using Vector Velocity Imaging (VVI. Methods: VVI of the LA and LV was acquired from apical four- and two-chamber views of 108 HCM patients (age 40±19years, 56.5% men and 33 healthy subjects, all had normal LV systolic function. The LA subendocardium was traced to obtain atrial volumes, ejection fraction, velocities, and strain (ɛ/strain rate (SR measurements. Results: Left atrial reservoir (ɛsys,SRsys and conduit (early diastolic SRe function were significantly reduced in HCM compared to controls (P-1.8s-1 was 81% sensitive and 30% specific, SRa>-1.5s-1 was 73% sensitive and 40% specific. By multivariate analysis global LVɛsys and LV septal thickness are independent predictors for LAɛsys, while end systolic diameter is the only independent predictor for SRsys, P<.001. Conclusion: Left atrial reservoir and conduit function as measured by VVI were significantly impaired while contractile function was preserved among HCM patients. Left atrial deformation was greatly influenced by LV mechanics and correlated to severity of phenotype.

    Full Text Available We report herein a case of idiopathic adrenal hematoma. A 59-year-old Japanese man was referred to our hospital for evaluation of a 7.0 cm mass in the right upper abdominal cavity. The tumor was suspected to originate from either the posterior segment of the liver or the right adrenal gland. His chief complaint was weight loss of 8 kg over the previous 6 months. He had no past medical history and took no medications, including no anticoagulants. Laboratory data were almost normal except for a slight elevation of PIVKA-II. The origin of the tumor was found to be the adrenal gland, as angiography revealed the blood supply to the mass to derive from the right superior and inferior adrenal arteries. A fine needle biopsy of the lesion was unable to confirm the diagnosis. Open right adrenalectomy was performed. The histopathological findings of the surgical specimen revealed a hematoma with normal adrenal tissue. In the absence of any obvious etiology, the diagnosis was idiopathic adrenal hematoma.

    Full Text Available To investigate the performance of hematoma shape, hematoma size, Glasgow coma scale (GCS score, and intracerebral hematoma (ICH score in predicting the 30-day mortality for ICH patients. To examine the influence of the estimation error of hematoma size on the prediction of 30-day mortality.This retrospective study, approved by a local institutional review board with written informed consent waived, recruited 106 patients diagnosed as ICH by non-enhanced computed tomography study. The hemorrhagic shape, hematoma size measured by computer-assisted volumetric analysis (CAVA and estimated by ABC/2 formula, ICH score and GCS score was examined. The predicting performance of 30-day mortality of the aforementioned variables was evaluated. Statistical analysis was performed using Kolmogorov-Smirnov tests, paired t test, nonparametric test, linear regression analysis, and binary logistic regression. The receiver operating characteristics curves were plotted and areas under curve (AUC were calculated for 30-day mortality. A P value less than 0.05 was considered as statistically significant.The overall 30-day mortality rate was 15.1% of ICH patients. The hematoma shape, hematoma size, ICH score, and GCS score all significantly predict the 30-day mortality for ICH patients, with an AUC of 0.692 (P = 0.0018, 0.715 (P = 0.0008 (by ABC/2 to 0.738 (P = 0.0002 (by CAVA, 0.877 (P<0.0001 (by ABC/2 to 0.882 (P<0.0001 (by CAVA, and 0.912 (P<0.0001, respectively.Our study shows that hematoma shape, hematoma size, ICH scores and GCS score all significantly predict the 30-day mortality in an increasing order of AUC. The effect of overestimation of hematoma size by ABC/2 formula in predicting the 30-day mortality could be remedied by using ICH score.

    @@ Retroperitoneal hematoma is an obligatory complication in pelvic ring fracture.1 In most cases, the bleeding originates from venous vessels of the presacral plexus, small arteries and veins from fracture fragments. External fixation of the pelvis can control blood loss by reducing diastasis and dramatically decreasing the volume of the pelvis. But this tamponade effect can not prevent the presence of hematoma in the adjoining retroperitoneal space. It is well known that complication of retroperitoneal hematoma is infection and sepsis.

    Full Text Available Background and Objective. Although minimally invasive surgical treatment of acute epidural hematoma attracts increasing attention, no generalized indications for the surgery have been adopted. This study aimed to evaluate the effects of minimally invasive surgery in acute epidural hematoma with various hematoma volumes. Methods. Minimally invasive puncture and aspiration surgery were performed in 59 cases of acute epidural hematoma with various hematoma volumes (13–145 mL; postoperative follow-up was 3 months. Clinical data, including surgical trauma, surgery time, complications, and outcome of hematoma drainage, recovery, and Barthel index scores, were assessed, as well as treatment outcome. Results. Surgical trauma was minimal and surgery time was short (10–20 minutes; no anesthesia accidents or surgical complications occurred. Two patients died. Drainage was completed within 7 days in the remaining 57 cases. Barthel index scores of ADL were ≤40 (n=1, 41–60 (n=1, and >60 (n=55; scores of 100 were obtained in 48 cases, with no dysfunctions. Conclusion. Satisfactory results can be achieved with minimally invasive surgery in treating acute epidural hematoma with hematoma volumes ranging from 13 to 145 mL. For patients with hematoma volume >50 mL and even cerebral herniation, flexible application of minimally invasive surgery would help improve treatment efficacy.

    A combined septal perforation repair and rhinoplasty was performed in 20 patients (12 males, eight females; age range 16-36, mean age 29.6) presenting with septal perforations (size 1-4 cm) and external nasal deformities. The external rhinoplasty approach was used for all cases and the perforation was repaired using bilateral intranasal mucosal advancement flaps with a connective tissue interposition graft in between. The perforation was totally closed in 18 cases (90 per cent) with complete resolution of the pre-operative symptoms occurring in 16 (80 per cent). Cosmetically, 19 cases (95 per cent) were very satisfied with their aesthetic result. The exposure provided by the external approach proved to be very helpful in the process of septal perforation repair. Our results show that septal perforation repair could safely be combined with rhinoplasty and that some of the rhinoplasty manoeuvres used could even facilitate the process of septal perforation repair.

    Full Text Available Left atrial appendage (LAA occlusion is a treatment strategy to prevent blood clot formation in atrial appendage. Although, LAA occlusion usually was done by catheter-based techniques, especially percutaneous trans-luminal mitral commissurotomy (PTMC, it can be done during closed and open mitral valve commissurotomy (CMVC, OMVC and mitral valve replacement (MVR too. Nowadays, PTMC is performed as an optimal management of severe mitral stenosis (MS and many patients currently are treated by PTMC instead of previous surgical methods. One of the most important contraindications of PTMC is presence of clot in LAA. So, each patient who suffers of severe MS is evaluated by Trans-Esophageal Echocardiogram to rule out thrombus in LAA before PTMC. At open heart surgery, replacement of the mitral valve was performed for 49-year-old woman. Also, left atrial appendage occlusion was done during surgery. Immediately after surgery, echocardiography demonstrates an echo imitated the presence of a thrombus in left atrial appendage area, although there was not any evidence of thrombus in pre-pump TEE. We can conclude from this case report that when we suspect of thrombus of left atrial, we should obtain exact history of previous surgery of mitral valve to avoid misdiagnosis clotted LAA, instead of obliterated LAA. Consequently, it can prevent additional evaluations and treatments such as oral anticoagulation and exclusion or postponing surgeries including PTMC.

    Full Text Available We describe an interesting case of intramural duodenal hematoma in an otherwise healthy male who presented to emergency room with gradually progressive abdominal pain, nausea, and vomiting. This condition was missed on initial evaluation and patient was discharged from emergency room with diagnosis of acute gastritis. After 3 days, patient came back to emergency room and abdominal imaging studies were conducted which showed that patient had intramural duodenal hematoma associated with gastric outlet obstruction and pancreatitis. Hematoma was the cause of acute pancreatitis as pancreatic enzymes levels were normal at the time of first presentation, but later as the hematoma grew in size, it caused compression of pancreas and subsequent elevation of pancreatic enzymes. We experienced a case of pancreatitis which was caused by intramural duodenal hematoma. This case was missed on initial evaluation. We suggest that physicians should be more vigilant about this condition.

Immunohistochemistry study confirmed that the cells were hematopoietic components predominantly composed of normoblasts. In this paper, we describe the clinical and pathological findings. A brief review of published information on extramedullary hematopoiesis in subdural hematoma and the mechanisms of pathogenesis are also discussed. While extramedullary hematopoiesis is seen anecdotally by neuropathologists in chronic subdural hematomas, only a few cases are documented in the literature. Furthermore, extramedullary hematopoiesis in subdural hematoma can pose a diagnostic challenge for general pathologists who encounter subdural hematoma evacuations seldom in their surgical pathology practices.

    Acute epidural hematoma not associated with head injury is rarely encountered and is known as spontaneous epidural hematoma. To our knowledge, only five cases with epidural hematoma after open-heart surgery have been published. Pathogenesis and preventive measures have not yet been determined. We report a case of such spontaneous epidural hematoma and consider the possible pathogenesis. A 12-year-old female received a radical operation for severe subaortic stenosis. The intraoperative course was uneventful except for massive hemorrhage which was adequately controlled. Postoperatively, she was moved to the CCU still not having aroused from anesthesia. Eleven hours later, it was found that her pupils were fixed and dilated. CT scan demonstrated a huge bifrontal epidural hematoma with disappearance of the basal cistern. Even though immediate emergency evacuation was performed, the patient died of acute brain swelling four days after the operation.

    Full Text Available Acute posterior fossa subdural hematomas are rare and most of them are trauma-related. Non-traumatic ones have been reported in patients who had idiopathic thrombocytopenic purpura or those who had been receiving anticoagulant therapy. We report on the case of 57-year-old Iranian man who developed sudden severe occipital headache, drowsiness, repeated vomiting, and instability of stance and gait. He was neither hypertensive nor diabetic. No history of head trauma was obtained and he denied illicit drug or alcohol ingestion. A preliminary diagnosis of acute intra-cerebellar hemorrhage was made. His CT brain scan revealed an acute right-sided, extra-axial, crescent-shaped hyperdense area at the posterior fossa. His routine blood tests, platelets count, bleeding time, and coagulation profile were unremarkable. The patient had spontaneous acute infratentorial subdural hematoma. He was treated conservatively and discharged home well after 5 days. Since then, we could not follow-up him, clinically and radiologically because he went back to Iran. Our patient’s presentation, clinical course, and imaging study have called for conservative management, as the overall presentation was relatively benign. Unless the diagnosis is entertained and the CT brain scan is well-interpreted, the diagnosis may easily escape detection.

The hemorrhagic risk with warfarin depends mainly on the international normalized ratio (INR. Data from randomized controlled trials show that patients have a therapeutic INR (2.00–3.00 only 61%–68% of the time while taking warfarin, and this target is sometimes hard to establish. Many compounds have been developed in order to optimize the profile of oral anticoagulants. We focus on one of them, rivaroxaban, comparing it with novel alternatives, ie, dabigatran and apixaban.

    Full Text Available Abstract Introduction Left atrial myxomas remain the most common benign primary cardiac tumors, and these cardiac growths can masquerade as mitral stenosis, infective endocarditis and collagen vascular disease. Atrial myxomas are found in approximately 14-20% of the population and can lead to embolization, intercardiac obstructions, conduction disturbances and lethal valve obstructions. Case presentation An 84-year-old Hispanic man presented with complaints of dizziness upon standing, and with no prior history of heart murmurs, syncope, shortness of breath, or chest pain. Physical examination revealed evidence of orthostatic hypotension and a soft grade 1/6 systolic murmur at the left sternal border. A transthoracic echocardiogram revealed a large atrial myxoma occupying the majority of the left atrium, with the posterior border of the large atrial mass defined by eccentric mitral regurgitation identified during cardiac catheterization. Left atrial myxoma excision was performed, revealing a 7 × 6.5 × 4.5 cm atrial tumor attached to a 4 × 3 × 2 cm stalk of atrial septal tissue. Conclusion This patient didn't present with the common symptoms associated with an atrial myxoma, which may include chest pain, dyspnea, orthopnea, peripheral embolism or syncope. Two-dimensional echocardiography provides substantial advantages in detecting intracardiac tumors. We recommend a two-dimensional echocardiogram in the workup of orthostatic hypotension of unknown etiology after the common causes such as autonomic disorders, dehydration, and vasodilative dysfunctions have been ruled out. By illustrating this correlation between orthostasis and an atrial myxoma, we hope to facilitate earlier identification of these intracardiac growths.

    Full Text Available Introduction: Atrial conduction time has important hemodynamic effects on ventricular filling and is accepted as a predictor of atrial fibrillation. In this study we assessed atrial conduction time in patients with non ischemic dilated cardiomyopathy (NIDCMP and functional mitral regurgitation (MR and aimed to determine factors predicting atrial conduction time prolongation. Methods: Sixty five patients with non ischemic dilated cardiomyopathy who have moderate to severe MR and 60 control subjects were included in the study. In addition to conventional echocardiographic measures used to asses left ventricle and MR, atrial electromechanical coupling (time interval from the onset of P wave on surface electrocardiogram [ECG] to the beginning of A wave interval with tissue Doppler echocardiography [PA], intra- and interatrial electromechanical delay (intra and inter AEMD were measured. Results: The correlations between inter AEMD and left atrial (LA size, MR volume, isovolumetric relaxation time (IVRT, deceleration time (DT, systolic pulmonary artery pressure (PAPs, E/A ratio and E/e’ were very poor. Similarly, intra AEMD was not correlated to LA size , MR volume, IVRT, DT, PAPs, E/A ratio and E/e’. However, both inter AEMD and intra AEMD had good correlation with left ventricular mass index, tenting area (TA, tenting distance (TD, coaptation septal distance (CSD, sphericity index (SI. Conclusion: Prolongation of inter and intra AEMDs were found to be well correlated with parameters reflecting left ventricular and mitral annular remodeling.

    Full Text Available Sciatica is defined as pain in the sciatic nerve distribution. The most common reason of sciatica is radiculopathy due to lumbar disc hernia. Other causes can be congenital, acquired, infectious, neoplastic, or inflammatory. The piriformis syndrome is another cause. The pain starts in an insidious manner when the cause of sciatica is an extraspinal tumor. It is intermittent at first but a constant and progressive pain that does not decrease with position or rest gradually develops in all patients. The possibility of an intraabdominal or pelvic mass should always be considered and the relevant tests requested when the cause of the sciatica cannot be explained. We present an 83-year-old male who presented with non-traumatic and non-vascular lumbosacral plexopathy due to a large hematoma in the left adductor muscle following the use of warfarin sodium.

    Full Text Available ABSTRACTIn Latin America, Bothrops envenomation is responsible for the majority of accidents caused by venomous snakes. Patients usually present local edema, bleeding and coagulopathy. Visceral hemorrhage is extremely rare and considered a challenge for diagnosis and management. We report the first case of hepatic hematoma owing to the bothropic envenomation in a 66-year-old man who was bitten in the left leg. He presented local edema, coagulopathy, and acute kidney injury. Radiological findings suggested hepatic hematoma, with a volume of almost 3 liters. The hepatic hematoma was gradually absorbed without the need for surgical intervention with complete resolution in 8 months.

    Traumatic duodenal hematoma is a rare condition that is encountered in the paediatric age group following blunt abdominal trauma. It poses both a diagnostic and therapeutic challenge. The main concern is increased morbidity secondary to delayed diagnosis and associated occult injuries to the adjacent structures. Most of these hematomas resolve spontaneously with conservative management, and the prognosis is good. We present a case of a 15-year-old boy who had a delayed presentation of duodenal hematoma and acute pancreatitis, which was treated conservatively with complete resolution.

    Intracerebellar hemorrhage is very rare in term infants and only severe cases with massive intracranial hemorrhage, posthemorrhagic hydrocephalus and clinical deterioration due to increased intracranial pressure require neurosurgical evacuation. In recent adult studies endoscopic hematoma evacuation has been shown as a rapid, effective, and safe technique. A term newborn hospitalized for meconium aspiration syndrome showed hypertonia, jitteriness and abnormal amplitude integrated electroencephalogram findings. He was diagnosed with cerebellar hematoma which caused hydrocephalus by cranial magnetic resonance imaging (MRI). The hematoma was successfully evacuated neuroendoscopically as the first case in literature to our knowledge. Neurologic, a-EEG and MRI findings resolved.

    Lumbar or sacral nerve root compression is most commonly caused by intervertebral disc degeneration and/or herniation. Less frequently, other extradural causes may be implicated, such as infection, neoplasm, epidural hematoma, or ligamentum flavum pathology. We present the case of a patient with spontaneous ligamentum flavum hematoma compressing the L4 nerve root, without antecedent trauma. Although exceedingly rare, the diagnosis of ligamentum flavum pathology in general, and that of ligamentum flavum hematoma in particular, should be considered on those rare occasions when the etiology of lumbar or sacral nerve root compressions appears enigmatic on radiological studies. Usually surgical treatment produces excellent clinical outcome. (orig.)

    Full Text Available Bleeding and hematoma formation is rarely reported in percutaneous vertebroplasty procedure. An 84 year old male presented with a large paraspinal muscle hematoma after a percutaneous vertebroplasty. The patient had neither any prior bleeding disorder nor any anticoagulant treatment. Vital signs of the patient were unstable, and his hemoglobin level decreased daily. After a month of conservative treatment, including transfusion, cryotherapy, pain control and bed rest, his hemoglobin level remained stable and he showed relief from pain. Four months later, hematoma resolved spontaneously and he could walk without back pain.

    Magnetic resonance is highly sensitive for the detection of intraparenchymatous hemorrhage. The evolution of hematoma over time translates into changes in signal intensity. This means that we can determine when the hematoma presented and, in addition. follow its course. On the other hand, many intracranial processes developing association with hemorrhage, the recognition of which is, in some cases, of importance. We have studied 60 cerebral hematomas and have described the changes that will take place in their signal and the reasons for them. (author)

  13. Giant aneurysm of the atrial septum associated with premature closure of foramen ovale

    Directory of Open Access Journals (Sweden)

    Romaguera Rita L

    2005-08-01

    Full Text Available Abstract Premature closure or restriction of foramen ovale (PCFO is a rare congenital anomaly that can lead to a wide spectrum of cardiac malformations. This spectrum of secondary malformations appears to depend on the gestational timing of closure of the foramen ovale and to the degree of restriction. Earlier in the gestation, closure of the foramen has been associated with severe hypoplasia of the left ventricle whereas later closure has been associated with right heart failure and rarely with the formation of an aneurysm of the atrial septum. We describe the case of a 1 day old infant in whom PCFO resulted in severe right heart failure in addition to the formation of a giant atrial septal aneurysm.

    This review discusses atrial fibrillation according to the guidelines of Brazilian Society of Cardiac Arrhythmias and the Brazilian Cardiogeriatrics Guidelines. We stress the thromboembolic burden of atrial fibrillation and discuss how to prevent it as well as the best way to conduct cases of atrial fibrillatios in the elderly, reverting the arrhythmia to sinus rhythm, or the option of heart rate control. The new methods to treat atrial fibrillation, such as radiofrequency ablation, new oral direct thrombin inhibitors and Xa factor inhibitors, as well as new antiarrhythmic drugs, are depicted.

    We report an extremely rare case of traumatic cervical spinal subdural hematoma not related to intracranial injury. There has been no report on traumatic cervical spinal subdrual hematoma not related to intracranial injury. A 27-year-old female patient was admitted to our emergency room due to severe neck pain and right arm motor weakness after car collision. On admission, she presented with complete monoplegia and hypoesthesia of right arm. Magnetic resonance imaging (MRI) revealed subdural hematoma compressing spinal cord. Lumbar cerebrospinal fluid (CSF) analysis revealed 210,000 red blood cells/mm(3). She was managed conservatively by administrations of steroid pulse therapy and CSF drainage. Her muscle power of right arm improved to a Grade III 16 days after admission. Follow-up MRI taken 16th days after admission revealed almost complete resolution of the hematoma. Here, the authors report a traumatic cervical spinal SDH not associated with intracranial injury.

    We report a rare case of a meningioma causing acute hematoma. A 67-year-old woman presented with sudden headache. No evidence of trauma was seen. CT demonstrated a subdural hematoma in the convexity of the fronto-temporal lobe. Magnetic resonance imaging showed marked signal heterogeneity in the convexity of the frontal lobe. One week later, the patient underwent hematoma evacuation and tumor resection including the attached dura mater. The histological diagnosis was meningothelial meningioma. The clot was connected directly to the tumor and the origin of the subdural hematoma was identified as the meningioma. Postoperative course was uneventful, and the headache improved. Meningiomas have a relatively benign course but rarely present with hemorrhage. Surgical exploration is the effective and recommended treatment.

    2003-05-15

    We present a patient with a spontaneous iliacus muscle hematoma, appearing immediately after a minor physical maneuver, presenting with pain and femoral neuropathy initially evidenced by massive quadriceps muscle fasciculations. A magnetic resonance imaging (MRI) study of the pelvic area confirmed the diagnosis, showing a hematoma secondary to a partial muscle tear. The patient was managed conservatively, and the continuous muscle activity ceased in 3 days, with progressive improvement of the pain and weakness. The recovery was complete. Femoral neuropathy is uncommon and usually due to compression from psoas muscle mass lesions of diverse nature, including hematomas. Usually subacute, femoral neuropathy may present acutely in cases of large or strategically placed compressive femoral nerve lesions, and may require surgical evacuation. The case presented herein is remarkable since the muscle hematoma appeared after a nonviolent maneuver, fasciculations were present at onset, and conservative management was sufficient for a full recovery.

    Hepatic hematomas in newborn infants are not frequently detected clinically, but are often found at perinatal autopsies. These hematomas of the liver are usually subcapsular in location. A variety of etiologies for such hematomas has been implicated, such as trauma, sepsis, and coagulopathies. We present a neonate who presented with jaundice and abdominal distention. Initial imaging studies revealed a large intraparenchymal lesion of the liver, which was at first thought to be suspicious for neoplasm; however, MRI showed the lesion to be hemorrhagic and follow-up sonographic studies showed total resolution of this lesion, compatible with hematoma. The intraparenchymal location and the idiopathic nature of this lesion distinguish this case from others previously reported. (orig.)

    An iliopsoas hematoma can occur either spontaneously or secondary to trauma or bleeding tendency due to hemophilia and anticoagulant therapy. Although liver cirrhosis is commonly associated with coagulopathy, iliopsoas hematoma is very rare. We herein, present a case of bilateral iliopsoas hematoma in a patient with alcoholic cirrhosis, and review the literature on muscle hematoma associated with cirrhosis. A 56-year-old man with alcoholic cirrhosis was admitted in a state of shock with anemia. The cause of anemia could not be detected, and the patient was treated conservatively. The site of bleeding was not detected with either gastroduodenal endoscopy or upper abdominal computed tomography, the latter of which did not include the iliopsoas muscle. He died on the 10th day of admission and bilateral iliopsoas hematomas were found on autopsy. An iron stain was positive in the iliopsoas muscle. Eight cases of muscle hematoma associated with cirrhosis, including the present case, were found in a review of the literature. Four of these cases involved the rectus abdominis muscle, 3 involved the iliopsoas muscle and 1 involved combined muscles. Alcoholic cirrhosis accounted for 75% of the cases. One case (12.5%) was associated with virus-related cirrhosis, and another with combined virus-and alcohol-related cirrhosis. The mortality rate was 75% despite early diagnosis and low risk scores for cirrhosis. Muscle hematoma in patients with cirrhosis isclosely related to alcoholism, and the mortality rate of the condition is extremely high. In conclusion, muscle hematoma should be recognized as an important complication of cirrhosis.

    Background: Spinal hematomas are rare entities that can be the cause of an acute spinal cord compression syndrome. Therefore, an early diagnosis is of great importance. Patients and Methods: From 2001 to 2005 seven patients with intense back pain and/or acute progressive neurological deficit were studied via 1.5 T MRI (in axial and sagittal T1- and T2-weighted sequences). Follow-up MRI was obtained in six patients. Results: Four patients showed the MRI features of a hyperacute spinal hematoma (two spinal subdural hematoma [SSH] and two spinal epidural hematoma [SEH]), isointense to the spinal cord on T1- and hyperintense on T2-weighted sequences. One patient had an early subacute SEH manifest as heterogeneous signal intensity with areas of high signal intensity on T1- and T2-weighted images. Another patient had a late subacute SSH with high signal intensity on T1- and T2-weighted sequences. The final patient had a SEH in the late chronic phase being hypointense on T1- and T2-weighted sequences. Discussion: MRI is valuable in diagnosing the presence, location and extent of spinal hematomas. Hyperacute spinal hematoma and the differentiation between SSH and SEH are particular diagnostic challenges. In addition, MRI is an important tool in the follow-up in patients with conservative treatment.

    1998-05-03

    The atrioventricular septal defect is usually associated with trisomy 21 and it may be observed in the heterotaxia syndromes. Atrioventricular septal defect may be associated with 8p deletion. There are reported cases of familial atrioventricular septal defect. Atrioventicular septal defect is rarely associated with other chromosomal abnormalities. We are reporting three unusual cases of atrioventricular septal defect that were associated with trisomy 13, 18 and 22. This association may be due to effect of genetic loci on the 13, 18 and 22 chromosome which could play the role in the development and fusion of endocardial cushion and atrioventricular septal defect.

    Summary The developmental mechanisms underlying human congenital heart disease (CHD) are poorly understood. Atrial septal defects (ASDs) can result from haploinsufficiency of cardiogenic transcription factors including TBX5. We demonstrated that Tbx5 is required in the second heart field (SHF) for atrial septation in mice. Conditional Tbx5 haploinsufficiency in the SHF but not the myocardium or endocardium caused ASDs. Tbx5 SHF knockout embryos lacked atrial septum progenitors. We found that Tbx5 mutant SHF progenitors demonstrated cell-cycle progression defects and that Tbx5 regulated cell-cycle progression genes including Cdk6. Activated hedgehog (Hh) signaling rescued ASDs in Tbx5 mutant embryos, placing Tbx5 upstream or parallel to Hh in cardiac progenitors. Tbx5 regulated SHF Gas1 and Osr1 expression, supporting both pathways. These results describe a SHF Tbx5-Hh network required for atrial septation. A paradigm defining molecular requirements in SHF cardiac progenitors for cardiac septum morphogenesis has implications for the ontogeny of CHD. PMID:22898775

    Full Text Available Sébastien Lobet,1,2 Cedric Hermans,1 Catherine Lambert1 1Hemostasis-Thrombosis Unit, Division of Hematology, 2Division of Physical Medicine and Rehabilitation, Cliniques Universitaires Saint-Luc, Brussels, Belgium Abstract: Hemophilia is a hematological disorder characterized by a partial or complete deficiency of clotting factor VIII or IX. Its bleeding complications primarily affect the musculoskeletal system. Hemarthrosis is a major hemophilia-related complication, responsible for a particularly debilitating chronic arthropathy, in the long term. In addition to clotting factor concentrates, usually prescribed by the hematologist, managing acute hemarthrosis and chronic arthropathy requires a close collaboration between the orthopedic surgeon and physiotherapist. This collaboration, comprising a coagulation and musculoskeletal specialist, is key to effectively preventing hemarthrosis, managing acute joint bleeding episodes, assessing joint function, and actively treating chronic arthropathy. This paper reviews, from a practical point of view, the pathophysiology, clinical manifestations, and treatment of hemarthrosis and chronic hemophilia-induced arthropathy for hematologists, orthopedic surgeons, and physiotherapists. Keywords: hemophilia, arthropathy, hemarthrosis, hematoma, physiotherapy, target joint

    Full Text Available A 74 year-old patient with a nocturnal onset of neck and chest pain was brought to an emergency clinic. Physical examination and cardiac assessment were normal. Three hours after the addmittance, a flaccid paralysis of the four limbs supervened. Suspecting of an unusual onset of central nervous system infection, a lumbar puncture was performed, yielding 20 ml of normal cerebrospinal fluid. Thirty oinutes after the puncture, the patient completely regained neurological funcion. He was then referred to a General Hospital where a computed tomography (CT scan was done showing a large cervical epidural bleeding in the posterolateral region of C4/C5 extending to C7/Th1, along with a C6 vertebral body hemangioma. A magnetic resonance imaging revealed the same CT findings. A normal selective angiography of vertebral arteries, carotid arteries and thyreocervical trunk was carried out. Spontaneous spinal epidural hematoma (ASSEH is a rare but dramatic cause of neurological impairment. In this article we report a fortunate case of complete recovery after an unusual spine cord decompression. We also review the current literature concerning diagnosis and treatment of ASSEH.

    Objective. To systematically review the international literature for internal nasal septal deviation classification systems and summarize them for clinical and research purposes. Data Sources. Four databases (including PubMed/MEDLINE) were systematically searched through December 16, 2015. Methods. Systematic review, adhering to PRISMA. Results. After removal of duplicates, this study screened 952 articles for relevance. A final comprehensive review of 50 articles identified that 15 of these articles met the eligibility criteria. The classification systems defined in these articles included C-shaped, S-shaped, reverse C-shaped, and reverse S-shaped descriptions of the septal deviation in both the cephalocaudal and anteroposterior dimensions. Additional studies reported use of computed tomography and categorized deviation based on predefined locations. Three studies graded the severity of septal deviations based on the amount of deflection. The systems defined in the literature also included an evaluation of nasal septal spurs and perforations. Conclusion. This systematic review ascertained that the majority of the currently published classification systems for internal nasal septal deviations can be summarized by C-shaped or reverse C-shaped, as well as S-shaped or reverse S-shaped deviations in the anteroposterior and cephalocaudal dimensions. For imaging studies, predefined points have been defined along the septum. Common terminology can facilitate future research. PMID:26933510

    2014-04-01

    Full Text Available Introduction: Lower end of humerus shows olecranon and coronoid fossae separated by a thin bony septum, sometimes it may deficient and shows foramen which communicates both the fossae called Septal aperture, which is commonly referred as supratrochlear foramen (STF. Materials & Methods: We have studied 260 humeri (126 right side and 134 left side, measurements were taken by using vernier caliper, translucency septum was observed by keeping the lower end of humerus against the x-ray lobby. Results: A clear cut STF was observed in 19.2% bones, translucency septum was observed in 99 (91.6% humeri on the right side and 95 (93.1% humeri on the left sides respectively (Table – 1. Clinical significance: The presence of STF is always associated with the narrow medullary canal at the lower end of humerus, Supracondylar fracture of humerus is most common in paediatric age group, medullary nailing is done to treat the fractures in those cases the knowledge about the STF is very important for treating the fractures. It has been observed in x-ray of lower end of the humerus the STF is comparatively radiolucent, it is commonly seen as a type of ‘pseudolesions’ in an x-ray of the lower end of humerus and it may mistake for an osteolytic or cystic lesions. Conclusion: The present study can add data into anthropology and anatomy text books regarding STF and it gives knowledge of understanding anatomical variation of distal end of the humerus, which is significant for anthropologists, orthopaedic surgeons and radiologists in habitual clinical practice.

    2015-01-01

    Full Text Available Left atrial (LA volumes are known to be increased in hypertrophic cardiomyopathy (HCM and are a predictor of adverse outcome. In addition, LA function is impaired and is presumed to be due to left ventricular (LV diastolic dysfunction as a result of hypertrophy and myocardial fibrosis. In the current study, we assess the incremental effect of outflow tract obstruction (and concomitant mitral regurgitation on LA function as assessed by LA strain. Patients with HCM (50 obstructive, 50 nonobstructive were compared to 50 normal controls. A subset of obstructive patients who had undergone septal myectomy was also studied. Utilising feature-tracking software applied to cardiovascular magnetic resonance images, LA volumes and functional parameters were calculated. LA volumes were significantly elevated and LA ejection fraction and strain were significantly reduced in patients with HCM compared with controls and were significantly more affected in patients with obstruction. LA volumes and function were significantly improved after septal myectomy. LVOT obstruction and mitral regurgitation appear to further impair LA mechanics. Septal myectomy results in a significant reduction in LA volumes, paralleled by an improvement in function.

    The objective of this study was to evaluate the age distribution, mode of injury, type of hematomas, and their surgical outcome in patients with bilateral traumatic head injuries. The present study included 669 cases of traumatic head injury who presented at the neurosurgery emergency out of which 94 cases had bilateral head injuries from the period of August 2009 to April 2014. The data from the hospital computerized database were retrospectively analysed. Cases of bilateral traumatic head injury included 94 patients out of which 88.29 % (n = 83) were males and 11.70 % (n = 11) were females. Commonest mode of injury was road traffic accident in 56.38 % (n = 53) followed by fall from height in 29.78 % (n = 28). In our study, 25.53 % patients had epidural hematoma (EDH) with intracerebral hematoma (ICH) or contusion (n = 24), followed by EDH with subarachnoid hemorrhage (SAH) in 18.08 % (n = 17). At the time of discharge, all those patients managed conservatively had good Glasgow outcome scale (GOS) while with surgical intervention 58 % patients had good GOS, 19 % had moderate disability, and 9 % remained with severe disability. In cases of bilateral hematomas, EDH is most common and should be managed in neurosurgical emergency. Other combinations of bilateral intracranial hematomas should be managed according to the surgical indication and serial CT imaging.

    Splenic hematomas are infrequent complications of acute pancreatitis. In some cases, local factors that may play a role in the pathogenesis of the hematoma (thrombosis of the splenic artery or veins, intrasplenic pseudocysts, perisplenic adhesions, enzymatic digestion) are found. In the absence of local factors, the etiology of splenic hemorrhage remains unknown. We report two cases of splenic hematoma occurring during an acute necro-hemorrhagic pancreatitis associated with renal failure that required renal replacement therapy (hemodialysis and continuous arteriovenous hemodialysis). In both cases, more than half of splenic parenchyma was affected by multiple infarctions. No local factors responsible for the splenic abnormalities were detected in either case. Thrombosis of the splenic arterial microcirculation and a coagulation disorder consistent with disseminated intravascular coagulation was detected in one patient. In the second patient, coagulation disorders secondary to either liver disease, pancreatitis and its septic complications, or extracorporeal circuit heparinization for renal replacement therapy were present. Coagulation disorders should be considered whenever a splenic hematoma is found in a patient with acute pancreatitis. Disseminated intravascular coagulation may be the etiology of a splenic hematoma in acute pancreatitis.

    Objective: To sum up the causes of recurrence of chronic subdural hematoma (CSDH) from failure of trepanation and drainage and explore its prevention and treatment.Methods: From October 1988 to June 2002 a total of 358 patients with CSDH were treated with trepanation and drainage in our hospital. Among them 15 patients had recurrence of CSDH after operation. The data of the 15 patients were reviewed retrospectively.Results: Of the 15 patients, 13 were cured by retrepanation and redrainage, one cured by removal of hematoma by craniotomy with bone flap, and one, a 1-year old child, gave up reoperation due to severe encephalatrophy. Conclusions: Most CSDHs which recur after trepanation and drainage can be cured by retrepanation and redrainage. For the patients with repeated recurrence of CSDH removal of hematoma capsule can be considered. The causes of recurrence of CSDH are related to disease course, the thickness of hematoma capsule, the severity of encephalatraphy and whether the hematoma cavity is drained or irrigated completely, and operation methods.

    Background: In much of the Western hemisphere, mortality from traumatic acute extradural hematomas (AEDH) has been drastically brought down toward 0%. This is still not the case however in most developing countries. Case Description: This report represents a tragi-comic tale of two cases of traumatic AEDH managed by an academic neurosurgeon in a neurosurgically ill-resourced private health facility during a nationwide industrial strike action preventing clinical-surgical care in the principal author's University Teaching Hospital. A young man presented with altered consciousness, Glasgow Coma Score (GCS) 14/15, following a road accident. The cranial computed tomography (CT) scan was obtained only 9 h after its request, long after the man had actually deteriorated to GCS 7/15 with pupillary changes. The neurosurgeon, summoned from the nearby University Teaching Hospital for the operative care of this man, arrived on-site and was about moving the patient into the operative room when he took the final breaths and died, all within 2 h of the belated neuroimaging. This scenario repeated itself in the same health facility just 24 h later with another young man who presented GCS 7/15 and another identical CT evidence of traumatic AEDH. With more financially able relations, the diagnostic/surgical care of this second patient was much more prompt. He made a very brisk recovery from neurosurgical operative intervention. He is alive and well, 5-month postoperative. Conclusions: In most low-resourced health systems of the developing countries, a significant proportion of potentially salvageable cases of AEDH still perish from this disease condition.

    Intramural hematomas (IMH) are regarded as a hemorrhage into the aortic wall. In general a traumatic form can be differentiated from a spontaneous non-traumatic. There is a predisposition of IMH with arterial hypertension and mesoectodermal dysplastic syndromes. The diagnosis is established with the clinical presentation in combination with the findings of different imaging modalities. Acute and subacute discomfort associated with a tendency of collaps are considered as typical presenting complaints. A semicircular or concentric thickening of the aortic wall with the absence of blood flow or a dissection membran are typical findings in transesophageal echocardiography, computed tomography and magnetic resonance tomography. From a differential diagnostic point of view a distinction from atherosclerotic wall changes, intraluminal thrombi and inflammatory aortic diseases is essential. The IMH is considered as an early presentation of aortic dissection, put into and treated according to the Stanford classification. In the course of natural history an IMH can disappear, rupture or progress into a classic aortic dissection. (orig.) [German] Das intramurale Haematom (IMH) ist eine Einblutung in die Aortenwand. Grundsaetzlich kann zwischen traumatischer Genese und einer atraumatischen spontanen Form unterschieden werden. Praedisponierend sind arterielle Hypertension und mesoektodermale Dysplasiesyndrome. Die Diagnose ergibt sich aus der Klinik und den Befunden in den bildgebenden Verfahren. Zu den klinischen Symptomen zaehlen akut oder subakut auftretende Schmerzen, assoziiert mit einer Kollapsneigung. Typische Befunde in der transoesophagealen Echokardiographie, der Computer- oder der Magnetresonanztomographie sind eine halbmondfoermige oder konzentrische Wandverdickung der Aorta ohne Nachweis von Blutfluss oder einer Dissektionsmembran mit Dichtewerten bzw. Signalintensitaeten in Abhaengigkeit vom Alter der Einblutung. Differenzialdiagnostisch ist eine Abgrenzung

    Full Text Available Introduction Ventricular septal defect (VSD is an opening in the interventricular septum. 30-50% of patients with congenital heart disease have VSD. Objective The aim of the study was to determine the dependence of the left ventricular diastolic dimension (LVD, left ventricular systolic dimension (LVS, shortening fraction (SF, left atrium (LA, pulmonary artery truncus (TPA on the body surface and compare their values among experimental, control and a group of healthy children. Values of maximal systolic gradient pressure (Pvsd of VSD were compared with children from one experimental and control group. Method Children were divided into three groups: experimental (32 children with VSD that were to go to surgery, control (20 children with VSD who did not require surgery and 40 healthy children. Measurements of LVD, LVS, SF, LA, TPA were performed in accordance to recommendations of the American Echocardiographic Association. The value of Pvsd was calculated from the maximal flow velocity (V in VSD using the following formula: Pvsd=4xVІ (mm Hg. Results For children from the experimental group, the relationship between the body surface and the variability of the LVD was explained with 56.85%, LVS with 66.15%, SF with 4.9%, TPA with 58.92%. For children from the control group, the relationship between the body surface and the variability of LVD was explained with 88.8%, LVS with 72.5%, SF with 0.42%, PA with 58.92%. For healthy children, the relationship between the body surface and the variabilitiy of the LVD was explained with 88.8%, LVS with 88.78%, SF with 5.25% and PA with 84.75%. There was a significant statistical difference between average values of Pvsd in the experimental and control group (p<0.02. Conclusion The presence of the large VSD has an influence on the enlargement of LVD, LVS, SF, TPA. The enlargement of the size of the pulmonary artery depends on the presence of VSD and there is a direct variation in the magnitude of the shunt

    This report presents the case of a 59-year-old man with sudden severe pain in the right lower abdomen after manually reducing the right indirect inguinal hernia who had bilateral indirect inguinal hernia for 5 years. A subsequent contrast computed tomography scan with contrast of the abdomen and pelvis revealed a significant extensive retroperitoneal hematoma at the abdomen and pelvis of the right side. There was contrast leaked out, which was suspected from inferior epigastric artery. He underwent successful laparotomy. The bleeding ruptured inferior epigastric artery at the interior side of the deep inguinal ring was found, the deep inguinal ring was avulsed, ligature of the inferior epigastric artery and removal of the retroperitoneal hematoma were done, and the patient was discharged from hospital on the seventh postoperative day. This is the first report in the literature on retroperitoneal hematoma caused by manual reduction of indirect inguinal hernia.

    Postpartum hemorrhage is an obstetrical emergency that represents the leading cause of maternal mortality. Severe hemorrhagic complications that could appear postpartum are the abdomino-pelvic hematomas, which result from the rupture of the pelvic vessels. We reported a very rare case of puerperal retroperitoneal subserosal hematoma of sigmoid colon following vaginal delivery, which was successfully managed by conservative methods. As far as we know, there are only a few case reports of intramural hematoma of sigmoid colon in literature, having other etiologies than vaginal delivery trauma. The particularities of the case consisted in the association of hemangiomas and the low risk thrombophilia. Diagnosis was based on the clinical exam and the paraclinical founding. Laparotomy is generally considered the last choice, in life threatening cases with hemodynamic instability, compression signs, and presence of contrast leakage on noninvasive imaging methods, but avoiding colonic resection after dissection represented the true challenge of the case.

    Full Text Available We report successful outcome of a huge post- trabeculectomy intra-bleb hematoma and hyphema that occurred following digital ocular compression. The patient was a 64-year-old lady suffering from bilateral primary angle closure glaucoma and cataract. She was on anti-platelet therapy. She underwent single-site phacoemulsification, intra-ocular lens implantation and trabeculectomy with mitomycin C in the right eye. The trabeculectomy was under-filtering. She was asked to perform digital ocular compression thrice daily. On 15 th post-operative day, she presented with a huge intra-bleb hematoma and hyphema. The hematoma did not respond to conservative measures and was drained to prevent bleb failure. We recommend caution in the consideration of digital ocular compression in patients on prophylactic anti-coagulation.

  7. Atrial fibrillation and heart failure: is atrial fibrillation a disease?

    Science.gov (United States)

    Tilman, V

    2014-09-01

    Atrial fibrillation in heart failure often occur together. The relationship between atrial fibrillation and heart failure has remained a subject of research. The main manifestation of the violation of hydrodynamics in heart failure is the increased end-diastolic pressure, which is transmitted through the intercommunicated system (left ventricle-left atrium-pulmonary veins-alveolar capillaries) causing increased pulmonary wedge pressure with the danger for pulmonary edema. End-diastolic pressure is the sum of left ventricle diastolic pressure and left atrial systolic pressure. Stopping the mechanical systole of the left atrium can reduce the pressure in the system in heart failure. Atrial fibrillation stops the mechanical systole of the left atrium and decreases the intercommunicating pressure and pulmonary wedge pressure. It is possible that atrial fibrillation is a mechanism for protection from increasing end-diastolic pressure and pulmonary wedge pressure, and prevents the danger of pulmonary edema. This hypothesis may explain the relationship between heart failure and atrial fibrillation and their frequent association.

  8. [Nosology and mechanism of monomorphous atrial tachycardia].

    Science.gov (United States)

    Puech, P

    1990-12-01

    Monomorphous atrial tachycardias have been classified taking into account the ectopic rhythm rate, atrial wave morphology, the mode of activation of the atrial studied by endocavitary cartography, stimulation tests and their natural history. Atrial flutter is a right intra-atrial macroreentry of anticlockwise (common flutter) or clockwise (atypical flutter) rotation, maintained by anisotropic conduction around two pivotal zones located at the posterior and inferior part of the atrium. Tachycardia is made possible by the existence of an excitable zone on the circuit. Paroxysmal atrial tachycardias are far more often linked to localised reentry (sino-atrial or intra-atrial microreentry) than to provoked activity, stimulation tests enabling the distinction to be made. "Digitalis tachycardias" must be seen in the context of activity induced by late post-potential. Focal atrial tachycardias linked to ectopic automatism are a separate entity. They follow a chronic course in the young individual and may lead to a cardiomyopathy purely due to the rhythm abnormality.

    Although bone infarction is a common feature in sickle cell disease, the involvement of the orbit is an unusual complication. Intracranial bleeding is another uncommon and serious complication. Few cases of orbital infarction alone have been reported. We report imaging findings (CT, bone scan, MRI) in a 16-year-old boy with sickle cell disease with orbital infarction and epidural hematoma. The precise cause of epidural hematoma is not well known, but it is probably related to vaso-occlusive episodes and the tearing of small vessels. (orig.)

    Full Text Available Duodenal intramural hematoma (DIH usually occurs in childhood and young adults following blunt abdominal trauma. It may also develop in the presence of coagulation disorders and may rarely be an iatrogenic outcome of endoscopic procedures. Management of DIH is usually a conservative approach. A case of intramural duodenal hematoma that developed following endoscopic epinephrine sclerotherapy and/or argon plasma coagulation and that was nonresponsive to conservative therapy in a patient with chronic renal failure who died from sepsis is being discussed in this report. Clinicians should be aware of such possible complications after endoscopic hemostasis in patients with coagulation disorders.

    A spontaneous retropharyngeal hematoma is a rare condition with a difficult diagnostic. This disease may rapidly progress to an airway obstruction. The author reports about a case of a 56-year-old man with an acute onset of sore throat, dysphonia and dyspnea. A retropharyngeal high attenuated soft tissue density could be seen on the neck CT. A rapid improvement of the retropharyngeal abnormality was seen on the 3 days follow-up MR imaging. Signal changes caused by blood products which were visible on the MRI images suggested the diagnosis of retropharyngeal hematoma. The patient was conservatively managed.

    Full Text Available Introducción: El hematoma epidural secundario a una anestesia neuroaxial es una complicación poco frecuente, pero de gran trascendencia tanto por sus implicaciones clínicas como por las médico legales; según algunos autores su incidencia puede oscilar entre 1/190.000-1/200.000 para las punciones peridurales y 1/320.000 en el caso de las espinales. El aspecto prioritario en su manejo terapéutico es el del diagnóstico y tratamiento precoz, antes de las 6-12 primeras horas. No obstante, en determinados pacientes como en el caso que presentamos puede no ser precisa la cirugía, resolviéndose el cuadro con tratamiento conservador. Caso clínico: Varón de 73 años, ASA IV, con antecedentes de cirrosis con hipertensión portal, hiperesplenismo, EPOC, obesidad, cardiopatía hipertensiva e insuficiencia tricuspídea. Se programa para alcoholización prostática al haber sido desechada la cirugía. En la analítica preoperatoria destacaba una actividad de protrombina del 80% y 90.000 plaquetas. Se realizaron varios intentos fallidos de punción espinal, finalmente fue precisa una anestesia general con ventilación espontánea mediante mascarilla laríngea, propofol, fentanilo y sevoflurano. A las 36 horas, comienza la clínica en forma de dolor intenso lumbar, sin irradiación y arreflexia cutáneo plantar, confirmándose en la RMN la presencia de un hematoma epidural de L1 a L4. Ante la ausencia de paraparesia flácida, afectación esfinteriana u otros signos sensitivo-motores y tras consulta con la Unidad de Raquis y con el Servicio de Neurología se decide tratamiento conservador y actitud expectante en forma de analgesia y monitorización neurológica estricta, clínica y radiológica. Evolucionando favorablemente en los siguientes días. Discusión: Determinadas condiciones clínicas pueden influir en la aparición de un hematoma tras la realización de un bloqueo regional central: heparinas de bajo peso molecular, punciones dificultosas

    Prolonged right ventricular (RV) apical pacing is associated with progressive left ventricular dysfunction due to dysynchronous ventricular activation and contraction. RV septal pacing allows a narrower QRS compared to RV apical pacing, which might reflect a more physiological and synchronous ventricular activation. Previous clinical studies, which did not consistently achieve RV septal pacing, were not confirmatory and need to be repeated. This review summarizes the anatomy of the RV septum, the radiographic appearances of pacing leads in the RV, the electrocardiograph correlates of RV septal lead positioning, and the techniques and tools required for implantation of an active-fixation lead onto the RV septum. Using the described techniques and tools, conventional active-fixation leads can now be reliably secured to either the RV outflow tract septum or mid-RV septum with very low complication rates and good long-term performance. Even though physiologic and hemodynamic studies on true RV septal pacing have not been completed, the detrimental effects of long-term RV apical pacing are significant enough to suggest that it is now time to leave the RV apex and secure all RV leads onto the septum.

    Background We hypothesize that increased atrial oxidative stress and inflammation may play an important role in atrial nerve sprouting and heterogeneous sympathetic hyperinnervation during atrial fibrillation (AF). To test the hypothesis, we examined whether the antioxidant and anti-inflammatory treatment with probucol attenuates atrial autonomic remodeling in a canine model of AF produced by prolonged rapid right atrial pacing. Methods Twenty-one dogs were divided into a sham-operated group, a control group and a probucol group. Dogs in the control group and probucol group underwent right atrial pacing at 400 beats per minute for 6 weeks, and those in the probucol group received probucol 1 week before rapid atrial pacing until pacing stopped. After 6-week rapid atrial pacing, general properties including left atrial structure and function, atrial hemodynamics and the inducibility and duration of AF were measured in all the groups. Atrial oxidative stress markers and serum C-reactive protein (CRP) concentration were estimated. The degree of nerve sprouting and sympathetic innervation at the right atrial anterior wall (RAAW) and the left atrial anterior wall (LAAW) were quantified by immunohistochemistry, atdal norepinephrine contents were also detected. Atrial beta-nerve growth factor (beta-NGF) mRNA and protein expression at the RAAW and LAAW were assessed by real-time quantitative RT-PCR and Western blotting respectively. Results Atrial tachypacing induced significant nerve sprouting and heterogeneous sympathetic hyperinnervation, and the magnitude of nerve sprouting and hyperinnervation was higher in the RAAW than in the LAAW. Atrial beta-NGF mRNA and protein levels were significantly increased at the RAAW and LAAW, and the upregulation of beta-NGF expression was greater at the RAAW than at the LAAW in the control group. The beta-NGF protein level was positively correlated with the density of sympathetic nerves in all groups. Probucol decreased the increase of

    Complex fractionated atrial electrogram (CFAE) has been suggested to contribute to the maintenance of atrial fibrillation (AF). However, electrophysiologic characteristics of the left atrial myocardium responsible for genesis of CFAE have not been clarified. Non-contact mapping of the left atrium was performed at 37 AF onset episodes in 24 AF patients. Electrogram amplitude, width, and conduction velocity were measured during sinus rhythm, premature atrial contraction (PAC) with long- (L-PAC), short- (S-PAC) and very short-coupling intervals (VS-PAC). These parameters were compared between CFAE and non-CFAE regions. Unipolar electrogram amplitude was higher in CFAE than non-CFAE during sinus rhythm, L-, S- and VS-PAC (1.82 ± 0.73 vs. 1.13 ± 0.38, p genesis of CFAE.

    Full Text Available In an adolescent girl with coexistent valvar pulmonary stenosis (PS and muscular ventricular septal defect (VSD causing right to left shunt and severe cyanosis, a series of complications were encountered during transcatheter intervention. After balloon pulmonary valvotomy (BPV and device closure of the VSD, dynamic infundibular hypercontractility elevated the right ventricular (RV systolic pressures leading to embolization of the device into the left ventricle. During retrieval of the device from the left ventricular outflow tract (LVOT, there was injury to the atrioventricular nodal tissue resulting in transient complete heart block. Even though the device was successfully retrieved out from the right femoral arterial access, there was a retroperitoneal hematoma causing severe anemia. A combination of dynamic infundibular obstruction, intravascular volume depletion caused by hemorrhage, low oxygen carrying capacity due to anemia, and inotropes resulted in a life-threatening hypercyanotic spell. Once this combination of suicidal hypercontractile right ventricle, anemia, and dehydration was recognized; management of the pathophysiology resulted in recovery of the patient. On a subsequent day, device closure of the VSD was complicated by unstable device position, but was finally achieved by an innovative device stabilization technique. We propose to explain the basis of hemodynamic and procedural complications, their recognition, and management. During preparatory stage before interventions in patients with multiple defects, which are linked by strong hemodynamic interdependence, meticulous planning should be done and multiple untoward events should be foreseen. While a few complications were completely unanticipated, some others could have been predicted.

    Spinal epidural hematoma and spinal epidural abscess are rare surgical emergencies resulting in significant neurologic deficits. Making the diagnosis for spinal epidural hematoma and spinal epidural abscess can be challenging; however, a delay in recognition and treatment can be devastating. The objective of this retrospective analysis study was to identify risk factors for an adverse outcome for the provider. The LexisNexis Academic legal search database was used to identify a total of 19 cases of spinal epidural hematoma and spinal epidural abscess filed against medical providers. Outcome data on trial verdicts, age, sex, initial site of injury, time to consultation, time to appropriate imaging studies, time to surgery, and whether a rectal examination was performed or not were recorded. The results demonstrated a significant association between time to surgery more than 48 hours and an unfavorable verdict for the provider. The degree of permanent neurologic impairment did not appear to affect the verdicts. Fifty-eight percent of the cases did not present with an initial deficit, including loss of bowel or bladder control. All medical professionals must maintain a high level of suspicion and act quickly. Physicians who are able to identify early clinical features, appropriately image, and treat within a 48 hour time frame have demonstrated a more favorable medicolegal outcome compared with their counterparts in filed lawsuits for spinal epidural hematoma and spinal epidural abscess cases.

    To describe the MR imaging and clinical findings of spontaneous spinal epidural hematoma. The MR and clinical findings in six patients (M:F=3D4:2;adult:child=3D3:3) with spontaneous spinal epidural hematoma were reviewed. Five patients without any predisposing factor which might cause the condition and one with acute myelogenous leukemia were included. Emergency surgery was performed in two patients, and the other four were managed conservatively. The epidural lesion involved between three and seven vertebrae (mean:4.5), and relative to the spinal cord was located in the posterior-lateral (n=3D4), anterior (n=3D1), or right lateral (n=3D1) area. The hematoma was isointense (n=3D1) or hyperintense (n=3D5) with spinal cord on T1-weighted images, and hypointense (n=3D2) or hyperintense (n=3D4) on T2-weighted images. It was completely absorbed in four of five patients who underwent follow-up MR imaging, but not changed in one. The clinical outcome of these patients was complete recovery (n=3D4), spastic cerebral palsy (n=3D1), or unknown (n=3D1). Because of the lesion's characteristic signal intensity; MR imaging is very useful in the diagnosis and evaluation of spontaneous spinal epidural hematoma. (author)

    Cardiac surgery for structural heart disease (often involving the left atrium) and radiofrequency catheter ablation of atrial fibrillation have led to an increased incidence of regular atrial tachycardias, often presenting as atypical flutters. This type of flutter is particularly common after pulmonary vein isolation, especially after extensive atrial ablation including linear lesions and/or defragmentation. The authors describe the case of a 51-year-old man, with no relevant medical history, referred for a cardiology consultation in 2009 for paroxysmal atrial fibrillation. After failure of antiarrhythmic therapy, he underwent catheter ablation, with criteria of acute success. Three years later he again suffered palpitations and atypical atrial flutter was documented. The electrophysiology study confirmed the diagnosis of atypical left flutter and reappearance of electrical activity in the right inferior pulmonary vein. This vein was again ablated successfully and there has been no arrhythmia recurrence to date. In an era of frequent catheter ablation it is essential to understand the mechanism of this arrhythmia and to recognize such atypical flutters.

    The myocardium of the right and left atrial appendages (auricles) in patients with paroxysmal, persistent, and permanent forms of atrial fibrillation was examined by histological methods and electron microscopy. Isolated atrial amyloidosis was detected in the left (50.0-56.3% patients) and in the right (45.0-55.6% patients) atrial appendages. In all cases, immunohistochemistry revealed atrial natriuretic peptide in fibrillary amyloid deposits. Ultrastructurally, amyloid masses formed clusters of myofibrils 8-10 nm in diameter. They were chaotically located in the extracellular space along the sarcolemma as well as in membrane invaginations, dilated tubules of cardiomyocyte T-tubular system, and vascular walls. Amyloidosis was predominantly observed in women; its degree positively correlated with age of patients and duration of atrial fibrillation but negatively correlated with atrial fibrosis. The study revealed positive (in permanent atrial fibrillation) and negative (in paroxysmal atrial fibrillation) correlation of amyloidosis with myofibril content in atrial cardiomyocytes.

    The etiology and proper treatment of symptomatic subacute subdural hematomas remains to be elucidated. We describe two cases of this entity successfully treated with small craniotomy and evacuation. Both patients initially treated conservatively for traumatic thin subdural hematomas because of poor medical condition and mild neurological symptoms, but suffered abrupt neurological deterioration between 2 and 3 weeks after the admission. CT scan showed decreased density of hematomas with minimal increase in volume, and significant swelling of ipsilateral cerebral hemisphere. Urgent two-burr-hole small craniotomy was effective for evacuation of partially organized hematoma. During surgery, definite hematoma membrane was not confirmed. Postoperatively, brain swelling rapidly disappeared and both patients discharged ambulatory without neurological deficit. The present cases are a reminder of this peculiar type of hematoma in patients with delayed neurological deterioration after nonsurgical management of acute subdural hematoma. The rationale for use of small craniotomy is discussed in terms of current understanding of pathogenetic mechanism for this unusual condition.

    Conclusions: The presence of a fracture over the MMA and intraparenchymal hematoma should prompt suspicion for a traumatic pseudoaneurysm. Pseudoaneurysms of the MMA can cause catastrophic bleeding, and prompt treatment is necessary. Endovascular embolization is an effective method that decreases the hemorrhage risk of MMA pseudoaneurysms.

    Full Text Available BACKGROUND: Atrial fibrillation is the most common cardiac dysrhythmia and left atrial size is an important factor in the development of atrial fibrillation. In the presence of atrial fibrillation an increase in left atrial size is associated with increased risk of stroke as well as increased morbidity and mortality. In this context, this study entitled “relation between left atrial size and atrial fibrillation in different diseases” was undertaken to study the left atrial size in different diseases causing atrial fibrillation and its relation to the atrial fibrillation. METHODS: A cross-sectional study was done from March 2004 to February 2006 in all medical units of Basaveshwar teaching and general hospital and Government general hospital Gulbarga. 70 cases of atrial fibrillation were studied in the present study. RESULTS: In the present study Atrial Fibrillation was common in >40 years age group (70%, left atrial enlargement was also more common in this age group (69.38%. Left atrial enlargement was seen in 70% of patients with Atrial Fibrillation. Rheumatic heart disease was the most common cause of Atrial Fibrillation (54.28% and left atrial enlargement was seen in 92% of these patients with mean left atrial size of 58.92 mm. Next most common cause was coronary artery disease (20% and left atrial enlargement was seen in 57.14% patients with a mean left atrial size of 39.5 mm. Left atrial size was normal in patients with thyrotoxicosis, congenital heart disease, lone Atrial Fibrillation and primary pulmonary hypertension. Left atrial enlargement was significantly associated with worsening of functional status (p<0.01, pulmonary arterial hypertension (p<0.005 and congestive cardial failure (p<0.02. 17.14% of patients with Atrial Fibrillation had embolic complications like stroke, of them left atrial enlargement was seen in 83.33% patients. 4.27% of patients with Atrial Fibrillation died during the hospital course, of them left atrial

    The anatomical substrates of internodal conduction have long been a contentious topic. Debated first by the German Pathological Society in 1910, the consensus of established opinion for over half a century was that conduction between sinus and atrioventricular nodes occurred through plain myocardium. This was a conclusion supported by Truex in 1961. Despite his restatement of this fact in 1976, it has become fashionable to describe internodal conduction as being mediated by specialized internodal pathways. To reinvestigate this problem we studied 22 human fetal and 32 human infant hearts. In each case it was possible to cut the atrial tissues as a single block of tissue and to examine serial sections through the internodal myocardium. The sinus node, atrioventricular node, and segments of atrioventricular ring specialized tissue were recognized as specialized tissue using the light microscope in each heart. In contrast, there was nothing "special" about the myocardium between the nodes, nor was it possible to recognize tracts on the basis of either histological appearance or cellular architecture. It is concluded that, from the standpoint of light microscopy, there is no evidence whatsoever to support the purported concept of specialized anatomical substrates for internodal conduction.

    2010-09-01

    The deviated nose represents a complex cosmetic and functional problem. Septal surgery plays a central role in the successful management of the externally deviated nose. This study included 800 patients seeking rhinoplasty to correct external nasal deviations; 71% of these suffered from variable degrees of nasal obstruction. Septal surgery was necessary in 736 (92%) patients, not only to improve breathing, but also to achieve a straight, symmetric external nose. A graduated surgical approach was adopted to allow correction of the dorsal and caudal deviations of the nasal septum without weakening its structural support to the nasal dorsum or nasal tip. The approach depended on full mobilization of deviated cartilage, followed by straightening of the cartilage and its fixation in the corrected position by using bony splinting grafts through an external rhinoplasty approach.

    先天性房室间隔缺损(atrioventricular sepial defect,AVSD)是一种常见的心血管畸形,由于存在房室间隔(房间隔下部、室间隔上部)以及中央心内膜垫组织的缺损,造成左右心腔之间的异常交通.虽然AVSD的胚胎学、病理生理学以及诊断和治疗目前都已基本阐明,但其确切的发病机制仍无突破性进展.随着分子生物学技术的广泛应用以及分子遗传学研究的深入开展,AVSD在遗传学的研究中取得一系列新进展,一些基因被证实与AVSD的发生发展存在一定的相关性.%Atrioventricular septal defect (AVSD) is a common cardiovascular malformation because of atrioventricular septal (lower atrial septum, ventricular septal upper) and the endocardial cushion defect,resulting in abnormal chambers of the heart. At the present, although the embryology, pathophysiology,diagnosis and treatment of the AVSD are clarified, but its precise pathogenesis has still no breakthrough progress.With the wide application of molecular biology and the depth research of molecular genetics, a series of new progress about AVSD has been made in the genetic study, and some genes are confirmed to be related to the occurrence and development of AVSD. The aim of this article is to review and discuss genetic mechanisms and related genes of AVSD, and to further identify the major genes causing AVSD.

    Isadora C Botwinick

    Full Text Available BACKGROUND: Atrial fibrillation and delayed gastric emptying (DGE are common after pancreaticoduodenectomy. Our aim was to investigate a potential relationship between atrial fibrillation and DGE, which we defined as failure to tolerate a regular diet by the 7(th postoperative day. METHODS: We performed a retrospective chart review of 249 patients who underwent pancreaticoduodenectomy at our institution between 2000 and 2009. Data was analyzed with Fisher exact test for categorical variables and Mann-Whitney U or unpaired T-test for continuous variables. RESULTS: Approximately 5% of the 249 patients included in the analysis experienced at least one episode of postoperative atrial fibrillation. Median age of patients with atrial fibrillation was 74 years, compared with 66 years in patients without atrial fibrillation (p = 0.0005. Patients with atrial fibrillation were more likely to have a history of atrial fibrillation (p = 0.03. 92% of the patients with atrial fibrillation suffered from DGE, compared to 46% of patients without atrial fibrillation (p = 0.0007. This association held true when controlling for age. CONCLUSION: Patients with postoperative atrial fibrillation are more likely to experience delayed gastric emptying. Interventions to manage delayed gastric function might be prudent in patients at high risk for postoperative atrial fibrillation.

    Full Text Available Spontaneous spinal epidural hematoma is a rare cause of acute spinal cord compression. A 25-year-old male presented with a history of sudden onset of complete quadriplegia with sensory loss below the neck along with loss of bowel and bladder control. He had no history of any constitutional symptoms. He reported 10 days later. He was managed conservatively and after two weeks of intensive rehabilitation he had complete neural recovery. The spontaneous recovery of neurological impairment is attributed to the spreading of the hematoma throughout the epidural space, thus decreasing the pressure with partial neural recovery. Conservative treatment is a fair option in young patients who present late and show neurological improvement. The neurological status on presentation will guide the further approach to management.

    We report a patient with minor head trauma-related bilateral hemispheric subdural hematoma (SDH) and subsequent delayed spinal SDH or presumed migration to the lumbar spine. An acutely confused 88-year-old man presented to the Emergency Department after minor head trauma. Head CT scan revealed a small hemispheric SDH. The patient was admitted for observation. CT scan 6 hours later showed bilateral SDH with extension to the tentorium. Three days later SDH had resolved leaving bilateral subdural hygromas. Local leg weakness localized to the lumbar spine developed on day 6; spinal CT scan and MRI revealed a posterior L5-S1 collection. A pure subacute subdural hematoma compressing the cauda equina was drained after an L5 laminectomy. His lower leg weakness improved. The patient was discharged to rehabilitation two weeks after surgery. Patients with traumatic SDH who develop late-onset neurological deterioration attributable to any region of the spine should be evaluated for spinal SDH.

    The aim of this study was to assess the possibility of revealing intracerebral hematomas (ICH), using MRI, within the first hours after onset and to determine their MRI semiotics features. Thirty animals with experimental ICH were studied. A method of two-stage introduction of autologous blood was used to develop ICH as human spontaneous intracranial hematomas. Within 3-5h after blood introduction to the rat brain. The control MRI was performed in the 3rd and 7th days after blood injections. ICH were definitely identified in the first MRI scans. The MRI semiotics features of acute ICH and their transformations were assessed. The high sensitivity of MRI to ICH as well as the uniform manifestations in all animals were shown. In conclusion, the method has high specificity for acute ICH detection.

    We report a rare case of a patient with spinal epidural hematoma who presented with transient hemiplegia. A 90-year-old man awakened from sleep due to sudden neck pain. Fifteen minutes later, the man experienced progressively worsening weakness in his left hand, and was transported in an ambulance to our hospital. At the hospital, he presented with hemiplegia, and we suspected intracranial disease. Therefore, we performed magnetic resonance imaging (MRI), which revealed no intracranial lesions. Shortly after the MRI, the patient showed no signs of hemiplegia. However, since the severe neck pain persisted, we performed cervical MRI, which showed a high-intensity area at the C2-C5 level, predominantly on the left side. Despite recovery from hemiplegia, we performed a laminectomy of C3-C5 with evacuation of a hematoma at the C2-C6 level. After the surgery, the patient had no neck pain.

    Thirty hearts from fetuses with visceral heterotaxy were examined to determine the range of cardiac malformations. By examining the morphology of the atrial appendages, 20 hearts were identified as having left isomerism (67%) and 10 hearts right isomerism (33%). Fifteen of the hearts with left isomerism had biventricular atrioventricular connections and five had univentricular atrioventricular connections. All 10 hearts with right isomerism had biventricular atrioventricular connections. Flow to the pulmonary arteries was obstructed or occluded in 6 hearts with left isomerism (30%) and 7 hearts with right isomerism (70%). Obstruction to aortic flow was present in 4 hearts with left isomerism (20%). Anomalies of the systemic and pulmonary veins were common in both groups. The suprarenal portion of the inferior caval vein was interrupted in 11 hearts with left isomerism (55%) and 1 heart with right isomerism (10%). Atrioventricular septal defect was present in 13 hearts with left isomerism (65%) and 9 hearts with right isomerism (90%). The arrangement of the liver or stomach in each group was not consistent, nor was the status of the spleen. The constellations of cardiac malformations in both groups corresponded to those known in postnatal life and similar guidelines for their identification were applicable.

    @@ Chronic subdural hematoma (CSDH) represents one of the most frequent types of intracranial hemorrhage. Management of the patients with CSDH has been evolved through a vast variety of methods and techniques. Although there is general agreement that surgical therapy is usually the preferred treatment, there are few other neurosurgical conditions that spark such strong discussions and differences of opinion concerning the optimal surgical technique.1,2 In this paper, we review advances in surgical treatment of CSDH.

    Background: Tentorial hematoma is frequently seen in traumatic brain injury (TBI) patients, especially in motorized two-wheeler riders following head injury. However its relevance and prognostic significance are not known. Objective: To evaluate patients of TBI with tentorial hematoma using a simple grading system and attempt to correlate this grading with factors like helmet use and neurological outcome. Materials and Methods: This prospective study over a 1-year period included patients with TBI who had tentorial hematoma in the initial plain head. Patients were divided into three grades based on the initial CT findings: Grade I: Isolated tentorial hematoma, grade II: tentorial hematoma with midline shift but open cisterns and grade III: Tentorial hematoma with effaced cisterns. Clinical and radiological records of patients including admission GCS and GOS at discharge were assessed in all cases. Observations: A total of 1786 patients of TBI were admitted during the study period. Of these, 106 (5.9%) patients had tentorial hematoma. 84.9% (n = 90) were male and 15.1% (n = 16) were female with the mean age being 36.5 years (range 2-66 years). The mean admission GCS was 13, 11 and 8 in patients with grade I, II and III tentorial hematoma respectively. 43.4% (n = 46) of the patients had grade I, 32.1% (n = 34) had grade II and 24.5% (n = 26) patients had grade III tentorial hematoma. Seventy-one patients (84.5%) were riding motorized two wheelers with 63 (89%) wearing helmets. The majority of the patients wearing helmets (58.8%) had grade I hematoma with 35% (n = 22) having grade II hematoma and only 6.3% (n = 4) having grade III hematoma. Overall, there were 20 deaths. 50% (n = 10) of the deaths were in patients with grade III hematoma and 40% (n = 8) of the deaths were in patients with grade II hematoma. There were two (10%) deaths in patients with grade I hematoma (both unrelated to head injury). The mean GOS at the time of discharge was 5, 4.1 and 2.2 in patients

  11. A Case of Spontaneous Spinal Epidural Hematoma Mimicking Stroke

    2014-09-01

    Full Text Available Spontaneous spinal epidural hematoma is an uncommon cause of acute non-traumatic myelopathy and may present with various clinical phenotypes. Focal neurological symptoms can result in overlooking this differential diagnosis in patients presenting with neurological deficits and assuming the diagnosis of a stroke. Therefore, a thorough documentation of patient history is of great importance, since this can reveal symptoms suggestive of a different etiology. Here, we present a case of an 80-year-old female who was admitted with a hemiparesis without cortical or cranial neurological abnormalities. She mentioned of preceding shoulder and neck pain. Diagnosis of epidural hematoma was made by cervical magnetic resonance imaging. Symptoms resolved partially after surgical intervention. Our case illustrates the variation in the clinical presentation of spontaneous spinal epidural hematoma which can be misdiagnosed as stroke. Therefore, in patients with preceding neck, shoulder or interscapular pain and focal neurological deficits, this diagnosis should be included in the differential, particularly when cortical and cranial signs are lacking.

    Intracranial bleeding following stereoelectroencephalography (sEEG) is rare and commonly occurs early after electrode implantation. The authors report the case of a delayed intracranial hematoma following sEEG. This 10-year-old boy was referred to the authors' department to undergo an sEEG study for intractable epilepsy, with the hypothesis of a single localized epileptic zone in the left precentral region. To perform the exploration, 14 depth electrodes were implanted under stereotactic conditions. The results of a postoperative CT scan performed routinely at the end of the surgical procedure were normal. Eight days later, following an epileptic seizure, the child's condition worsened. The neurological examination revealed a left hemiparesis, agitation, and coma due to a right subdural hematoma with intraparenchymal bleeding. Despite a surgical evacuation followed by a decompressive craniectomy, the curative treatments were stopped 1 week later due to severe diffuse ischemic lesions found on MRI studies. This is the first observation of a delayed hematoma following an sEEG procedure. The mechanism underlying this complication remains unclear, but the rupture of a growing pseudoaneurysm caused by the electrode's implantation or the tearing of a neighboring vessel by an electrode were suspected. In consequence, physicians must remain vigilant during the entire sEEG recording period and probably also several days after electrode removal.

    The purpose of this study was to assess the usefulness of CT angiography (CTA) in patients with intracerebral hematoma. Eighteen patients with spontaneous intracerebral hematoma underwent CTA; 20-30 seconds after the onset of an injection of contrast media (100mL), with the use of a power injector, at a rate of 3mL/sec, scanning (30-second continuous exposure and 60-90mm length) was performed with a table speed of 2-3 mm/sec and section thickness of 2mm. The starting point selected was the floor of the sella turcica. The resulting data were reformatted by maximum intensity projection (MIP) after reconstruction at 1-mm intervals, and CTA findings were compared with those of conventional angiography (n=17), surgery (n=6), and postcontrast CT(n=10). The diagnostic findings of CTA included five arteriovenous malformations, two aneurysms, one venous angioma, and one venous sinus occlusion, while the remaining nine patients had no vascular lesion. In all cases, CTA findings correlated well with those of postcontrast CT. In one cases of arteriovenous malformation, however, the feeding artery and draining vein were not definite on CTA, and in one case of sinus occlusion, the full length of the superior sagittal sinus could not be delineated. In patients with spontaneous intracerebral hematoma, CTA is a valuable screening method. (author). 15 refs., 4 figs.

    Complex muscular ventricular septal defect poses difficult surgical management and is associated with high morbidity and mortality despite advancements in surgical therapy. Device closure of muscular ventricular septal defect has been encouraging and has been used in hybrid approach at a few centres. However, device closure has some limitations in patients with complex muscular ventricular septal defect. We report a case of perventricular device closure of a complex muscular ventricular septal defect in a beating heart with entrapped right ventricular disc and its surgical management.

    Fourteen patients who presented to the University Hospital of Kuala Lumpur between June 1981 and June 1991 were reviewed retrospectively. Nasal septal abscesses are uncommon and therefore there are limited reports in the medical literature. Early diagnosis and immediate therapy is mandatory to avoid cosmetic nasal deformity or intracranial infection. Two out of the fourteen patients developed saddle nose deformity and septal perforation because of delay in treatment, the cases were misdiagnosed by non-otolaryngologist as turbinates swelling. The leading cause of nasal septal abscess was non-surgical trauma which accounted for about 85.7%. The commonest pathogenic organism isolated from the pus of nasal septal abscess was Staphylococcus aureus.

    The authors recently operated on a boy four years of age with acute epidural hematoma showing an extravasation on the cerebral angiogram. The hematoma (hematoma volume 125 ml) was evacuated 7 hours after the head injury. The postoperative course was quite uneventful, and he was discharged a month after surgery without any neurologic deficits. The authors reviewed the literature and found 4 cases of acute epidural hematoma with extravasations in infants and children. In all cases the operative results were good. The age incidence and frequency of occurence overall for acute epidural hematomas, extravasations on cerebral angiograms and their mechanism, and the length of time from injury to operation were also discussed. It should be emphasized that, for acute epidural hematoma in infants and children, the early diagnosis and early surgery are essential to save the patients.

  17. Genetic basis of atrial fibrillation

    Full Text Available Atrial fibrillation is the most common sustained arrhythmia and remains as one of main challenges in current clinical practice. The disease may be induced secondary to other diseases such as hypertension, valvular heart disease, and heart failure, conferring an increased risk of stroke and sudden death. Epidemiological studies have provided evidence that genetic factors play an important role and up to 30% of clinically diagnosed patients may have a family history of atrial fibrillation. To date, several rare variants have been identified in a wide range of genes associated with ionic channels, calcium handling protein, fibrosis, conduction and inflammation. Important advances in clinical, genetic and molecular basis have been performed over the last decade, improving diagnosis and treatment. However, the genetics of atrial fibrillation is complex and pathophysiological data remains still unraveling. A better understanding of the genetic basis will induce accurate risk stratification and personalized clinical treatment. In this review, we have focused on current genetics basis of atrial fibrillation.

    Full Text Available Reports of retropharyngeal hematoma have been scarce in the anesthesiology literature. We report a patient whose trachea was difficult to intubate due to retropharyngeal hematoma after stabbing to the neck. A woman with a knife injury to the common carotid artery required emergency carotid arterioplasty. When tracheal intubation was attempted, marked swelling of the posterior pharyngeal wall made the vocal cords impossible to visualize. Preoperative computed tomography showed a retropharyngeal hematoma. The patient required mechanical ventilation for 2 days.

    Atrial fibrillation (AF), which prevalence increases with age, is a growing public health problem and a well known risk factor for stroke. On the other hand, dementia is one of the most important neurological disorders in the elderly, and with aging of the population in developed countries, the number of demented patients will increase in absence of prevention. In the past decade, several vascular risk factors (hypertension, obesity and metabolic syndrome, hypercholesterolemia) have been found, with various degree of evidence, to be associated with vascular dementia but also, surprisingly, with Alzheimer's disease. This review is devoted to the links between atrial fibrillation, cognitive decline and dementia. Globally, transversal studies showed a significant association between atrial fibrillation, cognitive decline and dementia. However, these studies are particularly sensitive to various biases. In this context, recent longitudinal studies of higher level of evidence have been conducted to assess the link between AF and dementia. One study disclosed a high incidence of dementia among patients suffering from atrial fibrillation during a 4.6 years follow-up. Similarly another study showed that atrial fibrillation was significantly associated with conversion from mild cognitive impairment to dementia during a 3 years follow-up. Nevertheless two other longitudinal studies did not find any significant association between AF and dementia, but this discrepancy should be interpreted taking into account that the comparability of all these studies is moderate because they were using different methodologies (population, cognitive testing, and mean follow-up). Possible explanatory mechanisms for the association between AF and the risk of dementia are proposed, such as thrombo-embolic ischemic damage and cerebral hypo perfusion due to fluctuations in the cardiac output. Thus, there is some evidence that FA could be associated with cognitive decline and dementia but this

    Pre-treatment with antiplatelet agents is described to be a risk factor for mortality after spontaneous intracerebral hemorrhage (ICH). However, the impact of antithrombotic agents on mortality in patients who undergo hematoma evacuation compared to conservatively treated patients with ICH remains controversial. This analysis is based on a prospective registry for quality assurance in stroke care in the State of Hesse, Germany. Patients' data were collected between January 2008 and December 2012. Only patients with the diagnosis of spontaneous ICH were included (International Classification of Diseases 10th Revision codes I61.0-I61.9). Predictors of in-hospital mortality were determined by univariate analysis. Predictors with Panticoagulants or antiplatelet agents was documented in 16.3% and 25.1%, respectively. Overall in-hospital mortality was 23.2%. In-hospital mortality was decreased in operatively treated patients compared to conservatively treated patients (11.6% versus 24.0%; Pantiplatelet pre-treatment had a significantly higher risk of death during the hospital stay after hematoma evacuation (odds ratio [OR]: 2.5; 95% confidence interval [CI]: 1.24-4.97; P=0.010) compared to patients without antiplatelet pre-treatment treatment (OR: 0.9; 95% CI: 0.79-1.09; P=0.376). In conclusion a higher rate of in-hospital mortality after pre-treatment with antiplatelet agents in combination with hematoma evacuation after spontaneous ICH was observed in the presented cohort.

    Causes of colonic and recto-sigmoid hematomas are multifactorial. Patients can present with a combination of dropping hemoglobin, bowel obstruction and perforation. Computed tomography imaging can provide clues to a diagnosis of intramural hematoma. We present a case of rectal hematoma and a review of current management literature. A 72-year-old male on therapeutic anticoagulation for a pulmonary embolism, was administered an enema resulting in severe abdominal pain unresponsive to blood transfusion. A sigmoid colectomy with end colostomy was performed. Although rare, colonic and recto-sigmoid hematomas should be considered as a possible diagnosis for adults with abdominal pain on anticoagulant therapy. PMID:28108634

    An uncommon case of chronic nontraumatic spinal epidural hematoma of the lumbar spine in a 75-year-old woman is reported. The patient presented with a 7-month history of low back pain and bilateral sciatica. Magnetic resonance imaging enabled a correct preoperative diagnosis revealing a nodular, well-circumscribed epidural mass with peripheral enhancement and signal intensities consistent with chronic hematoma, which extended from L2 to L3. Laminectomy of L2-L3 was performed and the hematoma was totally resected. Histological examination of the surgical specimen demonstrated a chronic encapsulated hematoma. No evidence of vascular malformation was found. The patient recovered fully after surgical treatment. (orig.)

    The [symbol: see text] sinus-catheter was used to treat purulent sinusitis with septal perforation or defective septum of the sinuses. The procedure described implies simultaneous introduction of two sinus-catheters the functioning channels of which unite into one output by means of T-joint. The method has been successfully tried in the treatment of exudative and aggravated chronic purulent hemisinusitis (6 cases). The authors hold that communication between nasal sinuses is not a contraindication for sinus-catheter application. This fact widely extends potentialities of its use.

    Hemolytic anemia has been reported to occur in the setting of aortic stenosis and prosthetic heart valves, but much more rarely in association with obstructive hypertrophic cardiomyopathy (HC). Of the few descriptions of hemolytic anemia secondary to HC, all but one case involved bacterial endocarditis contributing to left ventricular outflow tract obstruction. We present the case of a 67-year-old man with recurrent hemolytic anemia and HC, without infective endocarditis. Attempts at iron repletion and augmentation of beta-blocker therapy proved his anemia to be refractory to medical management. Ventricular septal myectomy led to the resolution of hemolysis, anemia, and its coexisting symptoms. PMID:26424952

    Full Text Available Abstract Introduction Septal deviation is a common disease seen in daily otorhinolaryngology practice and septoplasty is a commonly performed surgical procedure. Caudal septum deviation is also a challenging pathology for ear, nose, and throat specialists. Many techniques are defined for caudal septal deviation. Objective To evaluate the effectiveness of caudal septal extension graft (CSEG application in patients who underwent endonasal septoplasty for a short and deviated nasal septum. Methods Forty patients with nasal septal deviation, short nasal septum, and weak nasal tip support who underwent endonasal septoplasty with or without CSEG placement between August 2012 and June 2013 were enrolled in this study. Twenty patients underwent endonasal septoplasty with CSEG placement. The rest of the group, who rejected auricular or costal cartilage harvest for CSEG placement, underwent only endonasal septoplasty without any additional intervention. Using the Nasal Obstruction Symptom Evaluation (NOSE and Rhinoplasty Outcome Evaluation (ROE questionnaires, pre- and post-operative acoustic rhinometer measurements were evaluated to assess the effect of CESG placement on nasal obstruction. Results In the control group, preoperative and postoperative minimal cross-sectional areas (MCA1 were 0.44 ± 0.10 cm2 and 0.60 ± 0.11 cm2, respectively (p < 0.001. In the study group, pre- and postoperative MCA1 values were 0.45 ± 0.16 cm2 and 0.67 ± 0.16 cm2, respectively (p < 0.01.

    AIM: Diabetes has been associated with atrial fibrillation but the current evidence is conflicting. In particular knowledge regarding young diabetes patients and the risk of developing atrial fibrillation is sparse. The aim of our study was to investigate the risk of atrial fibrillation in patients...... with diabetes compared to the background population in Denmark. METHODS AND RESULTS: Through Danish nationwide registries we included persons above 18 years of age and without prior atrial fibrillation and/or diabetes from 1996 to 2012. The study cohort was divided into a background population without diabetes...... and a diabetes group. The absolute risk of developing atrial fibrillation was calculated and Poisson regression models adjusted for sex, age and comorbidities were used to calculate incidence rate ratios of atrial fibrillation. The total study cohort included 5,081,087 persons, 4,827,713 (95%) in the background...

    Patients with acute intracranial hematomas often require surgical drainage within the first four hours after traumatic brain injury (TBI) to avoid death or severe neurologic disability. CT and MRI permit rapid, noninvasive diagnosis of hematomas, but can be used only at a major health-care facility. At present, there is no device for noninvasive detection and characterization of hematomas in pre-hospital settings. We proposed to use an optoacoustic technique for rapid, noninvasive diagnosis and monitoring of hematomas, including intracranial hematomas. Unlike bulky CT and MR equipment, an optoacoustic system can be small and easily transported in an emergency vehicle. In this study we used a specially-designed blast device to inflict TBI in rats. A near-infrared OPO-based optoacoustic system developed for hematoma diagnosis and for blood oxygenation monitoring in the superior sagittal sinus (SSS) in small animals was used in the study. Optoacoustic signals recorded simultaneously from the SSS and hematomas allowed for measurements of their oxygenations. The presence of hematomas was confirmed after the experiment in gross pictures of the exposed brains. After blast the hematoma signal and oxygenation increased, while SSS oxygenation decreased due to the blastinduced TBI. The increase of the oxygenation in fresh hematomas may be explained by the leakage of blood from arteries which have higher blood pressure compared to that of veins. These results indicate that the optoacoustic technique can be used for early diagnosis of hematomas and may provide important information for improving outcomes in patients with TBI or stroke (both hemorrhagic and ischemic).

    This study aims to describe the unique characteristics of absorption fever in patients with a hematoma after percutaneous renal biopsy (PRB) and distinguish it from secondary infection of hematoma.We retrospectively studied 2639 percutaneous renal biopsies of native kidneys. We compared the clinical characteristics between 2 groups: complication group (gross hematuria and/or perirenal hematoma) and no complication group. The axillary temperature of patients with a hematoma who presented with fever was measured at 06:00, 10:00, 14:00, and 18:00. The onset and duration of fever and the highest body temperature were recorded. Thereafter, we described the time distribution of absorption fever and obtained the curve of fever pattern.Of 2639 patients, PRB complications were observed in 154 (5.8%) patients. Perirenal hematoma was the most common complication, which occurred in 118 (4.5%) of biopsies, including 74 small hematoma cases (thickness ≤3 cm) and 44 large hematoma cases (thickness >3 cm). Major complications were observed in only 6 (0.2%) cases resulting from a large hematoma. Of 118 patients with a perirenal hematoma, absorption fever was observed in 48 cases. Furthermore, large hematomas had a 5.23-fold higher risk for absorption fever than the small ones.Blood pressure, renal insufficiency, and prothrombin time could be risk factors for complications. Fever is common in patients with hematoma because of renal biopsy and is usually noninfectious. Evaluation of patients with post-biopsy fever is necessary to identify any obvious infection sources. If no focus is identified, empiric antibiotic therapy should not be initiated nor should prophylactic antibiotics be extended for prolonged durations. Absorption fevers will resolve in time without specific therapeutic interventions.

    To explore the infarct sites in patients with inferior wall acute myocardial infarction (AMI) concomitant with ST segment elevation in leads V1-V3 and leads V3R-V5R.Methods Five patients diagnosed as inferior, right ventricular, and anteroseptal walls AMI at admission were enrolled. Electrocardiographic data and results of isotope 99mTc-methoxyisobutylisonitrile (MIBI) myocardial perfusion imaging and coronary angiography (CAG) were analyzed.Results Electrocardiogram showed that ST segment significantly elevated in standard leads Ⅱ, Ⅲ, aVF, and leads V1-V3 , V3R-V5R in all five patients. The magnitude of ST segment elevation was maximal in lead V1 and decreased gradually from lead V1 to V3 and from lead V1 to V3R-V5R. There was isotope 99mTc-MIBI myocardial perfusion imaging defect in inferior and basal inferior-septal walls. CAG showed that right coronary artery was infarct-related artery.Conclusions The diagnostic criteria for basal inferior-septal wall AMI can be formulated as follows: ( 1 ) ST segment elevates ≥2 mm in lead V1 in the clinical setting of inferior wall AMI; (2) the magnitude of ST segment elevation is the tallest in lead V1 and decreases gradually from lead V1 to V3 and from lead V1 to V3R-V5R. With two conditions above, the basal inferior-septal wall AMI should be diagnosed.

    Methods:The newly developed device consists of two parts:the plunger and barrel. On one side, the barrel is bullet shaped with an opening tip. The plunger is located in the middle cavity of the tube barrel and extended out at the open-end. It was designed for strengthening the tube barrel and for convenience in performing the drainage procedure. It can be used by inserting the drainage tube into the lesion and pulling out the plunger, whereby blood will forcefully rise up inside the barrel, providing a satisfactory outcome. It is made for effusion drainage purposes. During the procedure, the drainage tip is placed at the deepest part of the intracranial hematoma to completely drain the blood. Moreover, the plunger fits tightly in the tube, preventing leakage during the operation. With the use of the device, brain can be separated. In addition, the device can help reduce the risk of cerebral damage because of the small operating area. The barrel sidewall has matching opening holes bilaterally and equally for exchanging substances between the inner and outer parts. The overlapping ratio in each horizontal pair is around 1/3–1/2. Each pair on the opposite side will form a different pressure. Thus, the opening holes will not easily get blocked with blood clot. Results: Blood and accumulated liquid from the deepest part of the intracranial hematoma can be directly drawn through the drainage tube without damaging a large area. The tube does not get blocked easily and allows for complete removal of the hematoma. Conclusions:The device is asuitable instrument for clinical application.

    Atrial fibrillation (AF) is an extremely common condition in the elderly, with increasing prevalence around the world as the population ages. AF may be associated with serious health consequences, including stroke, heart failure, and decreased quality of life, so that careful management of AF by geriatric health care providers is required. With careful attention to anticoagulation therapy, and prudent use of medications and invasive procedures to minimize symptoms, many of the adverse health consequences of AF can be prevented.

    Full Text Available BACKGROUND Atrial fibrillation (AF, the most common sustained cardiac rhythm disturbance, commonly occurs with rheumatic heart disease, particularly mitral stenosis. Hemodynamic impairment and thromboembolic events result in significant morbidity& mortality. Left atrial (LA enlargement is one of the elements that evolve in the natural history of mitral stenosis. The objective of this study is to study the relation between echo cardio graphically determined left atrial size and atrial fibrillation in mitral valve disease (MVD. METHODOLOGY 50 Patients with rheumatic heart disease with mitral valve disease were studied using ECG and ECHO, excluding patients with congenital heart diseases, non-rheumatic mitral valve disease, essential hypertension, patients undergone PTMC or valvuloplasty or valve replacement, coronary artery diseases, patients on antiarrhythmic drugs, pregnant women. Left atrial dimensions measured by ECHO in patients of MVD and AF on ECG were compared with the left atrial dimension of patients in sinus rhythm. RESULTS In this study 42 patients had left atrial size >40 mm, 29(93.55% of them were in atrial fibrillation and only 13(68.42% were in sinus rhythm. Among 8 patients with left atrial size <40 mm, 2(6.45% were in atrial fibrillation and 06(31.58% were in sinus rhythm with p<0.02 which is significant. CONCLUSION Atrial fibrillation incidence was common when left atrial dimension was above 40 mm. There is a quantitative relation between left atrial size measured echocardiographically and the presence or absence of atrial fibrillation. These results may have therapeutic implication in that it may be possible with echocardiography, to identify patients in sinus rhythm, who are at high risk of developing atrial fibrillation. Prophylactic anticoagulation, antiarrhythmic therapy or both might be considered in management to prevent embolism.

    Dengue fever, also known as breakbone fever, is an infectious tropical disease caused by the Dengue virus. It is associated with a number of complications, which are well documented. However, Dengue fever associated with rectus sheath hematoma (RSH) is a very rare complication. Only one case report has been published prior supporting the association of Dengue fever with RSH. We report a case of Dengue fever who presented with RSH and was successfully treated conservatively. RSH is also an uncommon cause of acute abdominal pain. It is accumulation of blood in the sheath of the rectus abdominis, secondary to rupture of an epigastric vessel or muscle tear.

    Development of collateral circulation belongs among the typical signs of aortic coarctation. Cerebral or spinal artery aneurysm formation with increased risk of subarachnoid hemorrhage represent the most common neurovascular complication of this disease. We report a case of a 20-year-old sportsman who developed acute non-traumatic paraplegia as a result of extensive spinal epidural hemorrhage from collateral vessels accompanying aortic coarctation which was unrecognized up to that time. To the best of our knowledge, acute spinal epidural hematoma as a complication of aortic coarctation has not been previously reported. (orig.)

    Full Text Available The authors report the case of a 50 year-old hypertensive male patient with a pontine hematoma. The clinical presentation was characterized by pure pyramidal deficit signs (no other signs or symptoms were present. A pure hemiplegia syndrome, although common in supratentorial lesions, is considered to be a rare event in pontine vascular lesions. The pathophysiologic mechanisms of these neurological findings are unclear. The exclusive involvement of the pyramidal tract in this case is likely due to a variation in the vascular anatomy of the pons but, in some cases, a vascular malformation may be the cause.

    Cerebral cortical contusions are one of the most common computed tomography findings in head-injured patients and common sequel of traumatic brain injury. These contusions tend to show a progressive increase in mass effect on repeated imaging, most small contusions do not require surgical evacuation. However, progression to subdural hematoma (SDH) in a late aspect is unique. Here we present a 71-year-old man with bifrontal contusion, who deteriorated 43 days after initial trauma with sudden onset of acute SDH. This unusual case suggests that neurosurgeons should be alert for the possibility of very late onset of acute SDH after bifrontal contusions.

    During septorhinoplasty, septal cartilage is frequently resected for various purposes but the L-strut is preserved. Numerous materials are inserted into the nasal dorsum during dorsal augmenation rhinoplasty without considering nasal structural safety. This study used a finite element method (FEM) to redefine the septal L-strut, to prevent collapse as pressure moved from the rhinion to the supratip breakpoint on the nasal dorsum and as the contact percentage between the caudal L-strut and the maxillary crest changed. We designed a 1-cm-wide L-strut model based on computed tomography data. At least 45% of the width of the L-strut in the inferior portion of the caudal strut must be preserved during septoplasty to stabilize the septum. In augmentation rhinoplasty, the caudal L-strut must either be preserved perfectly or reinforced to prevent collapse or distortion of the L-strut. The dorsal augmentation material must be fixed in an augmentation pocket to prevent movement of graft material toward the supratip breakpoint, which can disrupt the L-strut. We conducted a numerical analysis using a FEM to predict tissue/organ behavior and to help clinicians understand the reasons for target tissue/organ collapse and deformation. PMID:27073993

    The possible effect of genetic and environmental factors during pregnancy on the occurrence of ventricular septal defect (VSD) in the offspring was studied in 150 cases and 756 controls. The cases represented all verified VSDs in Finland during 1982-1983. The controls were randomly selected from all babies born during the same period. Case and control mothers were interviewed by midwives approximately three months after delivery using a structured questionnaire. Congenital heart disease was more prevalent among parents of cases than those of controls. Maternal alcohol consumption during the first trimester of pregnancy was more common among the mothers of VSD infants (47.0%) than among those of controls (38.0%, P less than 0.05). Exposure to organic solvents at work showed in logistic regression analysis an adjusted relative odds ratio of 1.8 (95% confidence interval 1.0-3.4). The risk of VSD was not associated with any of the maternal habits monitored, e.g. smoking, or coffee, tea, cola, acetosalicylic acid or diazepam consumption. Whether the mother was employed during the first trimester of pregnancy, and her exposure to anesthetic gases, disinfectants, pecticides, wood preservatives or video display terminals were not factors associated with the risk of ventricular septal defect.

    Ten elderly patients (73-87 years, 78.4 years on the average) with subcortical hematomas were divided into two groups according to the shape of the hematoma on a CT scan: a lobulated group (6 patients) and a global group (4 patients). The lobulated group had a history of hypertension in one patient. The hematomas extended widely around the parietal lobe and were accompanied by perifocal edema, brain shifts and subarachnoid hemorrhages, deep consciousness disturbances, and poor prognosis of life and function. Amyloid depositions in the arteries around the hematomas were confirmed histologically in one patient. The global group had a history of hypertension in two patients. The hematomas were localized in the parietal, temporal, or occipital lobe without perifocal edema, brain shift and subarachnoid hemorrhages, and accompanied by mild consciousness disturbances. The life prognosis was good, but the functional prognosis was poor, with a subsequent development of dementia. A lobulated subcortical hematoma is thought to be due to amyloid angiopathy, while a global subcortical hematoma is thought to be due to hypertension. A surgical evacuation is seldom indicated for either type of subcortical hematoma in elderly patients. (author).

    Objectives To determine the safety and value of esophageal radiography as a means of locating transseptal puncture. Methods 486 patients who underwent transseptal puncture were randomized into two groups. An esophagus radiographic method of locating tansseptal puncture site was applied in the study group( n = 243 ) and modified-Ross locating method was used in the control group ( n = 243 ). After successful location, transseptal puncture was made. We observed the success rate and incidence complications in the 2 groups.Results Left atrium impression in the study group was clearly seen. Nonetheless in 120 cases of control group,the left atria silhouette was not clearly visualised. The success rate of locating transseptal puncture site in the study group and control group were 100% and 50.6% respectively ( P<0.001 ). The success rate of transseptal puncture in the study group and control group was 99.6% and 45.7% respectively ( P<0.001 ). There were no complications associated with puncture in the study group and pericardial tamponade occurred in 1 control patient. Conclusions The esophagus radiographic method of locating transseptal puncture site is accurate,safe and simple to perform. Transseptal puncture has a high success rate with few complications.

Catheter ablation of AF is relatively new modality to convert AF to sinus rhythm. This study was aimed to elaborate efficacy of catheter ablation in mixed type of AF.Methods Thirty patients (age of 52 ± 8 yo comprised of 19 paroxysmal and 11 chronic AF underwent radiofrequency catheter ablation guided by electroanatomical CARTO™ mapping system. We used step wise ablation approach with circumferential pulmonary vein isolation (PVI as a cornerstone. Additional ablation comprised of roof line, mitral isthmus line, complex fractionated atrial electrogram (CFAE, septal line and coronary sinus ablation was done respectively if indicated. All patients were followed up to 1 year for AF recurrence.Results Circumferential PVI was successfully performed in all patients but one. Average follow up period was 11.5 months. More than 80% of all patients remain in sinus rhythm at the end of follow period which 62% of them were free from any anti-arrhythmic drug. No major complication in all patients series.Conclusion Radiofrequency ablation guided with electroanatomical mapping is effective and safe in mixed type of AF.

    Full Text Available Sublingual hematoma secondary to anticoagulation is a rare fatal condition. Hemorrhagic complications of warfarin are well-known. This particular case is unique because the patient was on warfarin for the past 2 years but did not develop the sublingual hematoma. However, a trauma by an attrited sharp cusp triggered the episode of the sublingual hematoma in this patient. Being a medical emergency, patient was promptly hospitalized in cardiac care unit and managed by medical team. The patient was transfused with 2 units of fresh frozen plasma and warfarin was temporarily stopped for 4 days. Alternate day regimen of warfarin was started after 4 days, and international normalized ratio dropped to 3. In dental management, enameloplasty of the mandibular first molar tooth was done to prevent trauma and ulcer development in the floor of the mouth. The hematoma resolved, and no new hematoma formation was observed for a period of 6 months.

    A 57-year-old woman previously diagnosed with blue rubber bleb nevus syndrome(BRBNS) reported hematemesis. BRBNS is a rare vascular anomaly syndrome consisting of multifocal hemangiomas of the skin and gastrointestinal(GI) tract but her GI tract had never been examined. An upper gastrointestinal endoscopy revealed a large bleeding esophageal hematoma positioned between the thoracic esophagus and the gastric cardia. An endoscopic injection of polidocanol was used to stop the hematoma from bleeding. The hematoma was incised using the injectionneedle to reduce the pressure within it. Finally, argon plasma coagulation(APC) was applied to the edge of the incision. The esophageal hematoma disappeared seven days later. Two months after the endoscopic the rapy, the eso phage alulcerhealed and the hemangioma did not relapse. This rare case of a large esophageal hematoma originating from a hemangioma with BRBNS was treated using a combination of endoscopic therapy with polidocanol injection, incision, and APC.

    Full Text Available Renal subcapsular hematoma is not an uncommon complication after extracorporeal short wave lithotripsy, trauma, renal angiographic procedures and spontaneously in patients of malignancy and in patients on anticoagulation. We present a patient who developed renal subcapsular hematoma after ureterorenoscopy, which has not been mentioned in literature ever. Clinical spectrum varies from spontaneous resolution through acute renal failure to Page kidney. Page kidney is the external compression of a kidney usually caused by a subcapsular hematoma associated with high blood pressure and occasional renal failure. It is named after Dr. Irvin Page who first demonstrated in 1939 that wrapping cellophane tightly around animal kidneys could cause hypertension. Various management options are mentioned in literature and depend upon the severity of hematoma. Percutaneous drainage is a successful option for the management of subcapsular hematoma in hemodynamic stable patients.

    Full Text Available We describe a case in which a patient with a past medical history of ovarian cancer received a diagnostic renal biopsy for an incidentally discovered renal mass. During left robotic partial nephrectomy (RPN, a perinephric hematoma was encountered. The hematoma was not present on preoperative imaging and was likely a result of the renal biopsy. The renal cell carcinoma (RCC and the associated hematoma were widely excised with negative surgical margins. On follow-up imaging at five months postoperatively, a recurrent renal mass at the surgical resection bed and several new nodules in the omentum were detected. During completion left robotic total nephrectomy and omental excision, intraoperative frozen sections confirmed metastatic RCC. We believe that a hematoma seeded with RCC formed as a result of the renal biopsy, and subsequent disruption of the hematoma during RPN caused contamination of RCC into the surrounding structures.

    Background Differential diagnosis of isolated calf muscle vein thrombosis (ICMVT) and gastrocnemius hematoma is essential for early identification of deep vein thrombosis (DVT).This study aimed to investigate the diagnostic value of high-frequency color Doppler ultrasound for differential diagnosis of ICMVT and gastrocnemius hematoma.Methods A retrospective case series of 35 ICMVT (M∶F,21∶14; mean age (64.5±10.6) years) and 23 gastrocnemius hematoma (M∶F,16∶7; mean age (75.4±11.8) years) patients with bilateral/unilateral lower limb pain was conducted between January 2006 and September 2012.Characteristics and the morphology of high-frequency color Doppler ultrasonography of the lower limb deep vein,great saphenous vein,calf muscles,skin,and soft tissue were examined.Results ICMVT hypoechoic signals were characterized by long,tube-like masses on longitudinal sections and oval masses on transverse sections,with apparent muscle thrombosis boundaries,distal and proximal venous connections,and,often,lower limb DVT.Gastrocnemius hematoma hypoechoic signals were characterized by large volumes,enhanced posterior hematoma echo,hyperechoic muscle boundaries,no hematoma blood flow,and no DVT,and clear differences in trauma/exercise-and oral anticoagulant-induced hematomas were readily apparent.According to the measurement,the ratio of long diameter/transverse diameter (D/T) in ICMVT patients was about less than 2.0,whereas in gastrocnemius hematoma patients the ratio was more than 2.0.Early stage isoechoic and hypoechoic signals were detected with gradually increasing ovular anechoic areas.Partial muscle fibers in the hematoma due to muscle fractures were apparent.Conclusion High-frequency color Doppler ultrasound was found to be a sensitive and reliable method for differential diagnosis of ICMVT and gastrocnemius hematoma due to trauma and exercise or prolonged oral anticoagulant use.

    Full Text Available Introduction and Objective: Spontaneous pharyngeal-laryngeal hematoma shows the importance of a complete ENT examination in the face of symptoms of banal appearance and a correct history that, in the case reported, unveiled the therapeutic use of anticoagulants. Case description: A 55 year old woman comes to emergency because of unexplained dysphagia. The inspection shows the presence of a hematoma in the pharyngeal-laryngeal region that, after the anticoagulant therapy was reversed, evolved favorably with conservative treatment. Discussion: In this case, apart from medical management performed by the hematology department, we focus our therapeutic approach in the protection of the airway and the prevention of a possible massive bleeding. Determining which patients require endotracheal intubation or tracheostomy and hemostatic surgery is the key to treatment. Conclusions: The anticoagulant therapy involves several complications that ENT specialists must consider in the face of clinical symptoms of dysphagia, dysphonia, dyspnea or signs of bleeding and they must know the possibilities of performance depending on the severity of each case.

    Material and Methods: Consecutive patients operated with a diagnosis of chronic subdural hematoma between January 2003 and December 2012 were reviewed retrospectively. Etiology and medical status of the patients at the time of admission were noted. Exact localization of the chronic subdural hematoma was detected by computed tomography scans and follow-up was maintained with magnetic resonance imaging. The outcome of the patients was evaluated one month after injury, by assesing activities of daily living. Results: Ninety-four consecutive patients met the eligibility criteria for the study. The mean age was 65 (range 45 to 85 years. In 74 (78.7% patients, head injury was the supposed origin. In 20 (21.3% patients, no trauma was evident. Most common symptom reported at the time of admission was headache (100%, and the most common neurological finding was confusion (87.2%. The majority of the patients had a mild neurological deficit with a Glascow Coma Scale score over eight. In general, 90.4% of cases were sufficiently treated by a single operation, while 9.6% needed a second procedure. During the follow-up, 91.5% of the patients returned to daily living activities on the first month kontrol. Conclusion: Surgical treatment of chronic subdural haematoma can give a high rate of complete recovery to normal life. [Cukurova Med J 2015; 40(1.000: 22-27

    2009-01-01

    Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. The prevalence of AF increases dramatically with age and is seen in as high as 9% of individuals by the age of 80 years. In high-risk patients, the thromboembolic stroke risk can be as high as 9% per year and is associated with a 2-fold increase in mortality. Although the pathophysiological mechanism underlying the genesis of AF has been the focus of many studies, it remains only partially understood. Conventional th...

    2012-01-01

    Full Text Available Background. B-type natriuretic peptide has been shown to be a very sensitive and specific marker of heart failure. In this study, we aimed to investigate the effect of percutaneous closure of ventricular septal defects with Amplatzer septal occluders on brain natriuretic peptide levels. Methods. Between 2008 and 2011, 23 patients underwent successfully percutaneous ventricular septal defect closure in 4 cardiology centers. Brain natriuretic peptide levels were measured in nine patients (4 male, mean ages were 25.3±14.3 who underwent percutaneous closure with Amplatzer occluders for membranous or muscular ventricular septal defects were enrolled in the study. Brain natriuretic peptide levels were measured one day before and one month after the closure. Patients were evaluated clinically and by echocardiography one month after the procedure. Results. Percutaneous closures of ventricular septal defects were successfully performed in all patients. There was not any significant adverse event in patients group during followup. Decrease in brain natriuretic peptide levels after closure were statistically significant (97.3±78.6 versus 26.8±15.6, =0.013. Conclusion. Brain Natriuretic Peptide levels are elevated in patients with ventricular septal defects as compared to controls. Percutaneous closure of Ventricular Septal Defect with Amplatzer occluders decreases the BNP levels.

    2009-01-01

    BACKGROUND: Atrial fibrillation is a major risk factor for ischemic stroke. However, the prognostic impact of atrial fibrillation among patients with stroke is not fully clarified. We compared patient characteristics, including severity of stroke and comorbidity, quality of in-hospital care...... and outcomes in a cohort of first-time ischemic stroke patients with and without atrial fibrillation. METHODS: Based on linkage of public medical databases, we did a population-based follow-up study among 3,849 stroke patients from the County of Aarhus, Denmark admitted in the period of 2003......-2007 and prospectively registered in the Danish National Indicator Project. RESULTS: Atrial fibrillation was associated with an adverse prognostic profile but not with an overall poorer quality of in-hospital care. Patients with atrial fibrillation had a longer total length of stay (median: 15 vs 9 days), and were...

  14. Excessive interatrial adiposity is associated with left atrial remodeling, augmented contractile performance in asymptomatic population

    2016-05-01

    Full Text Available Purpose: Pericardial adipose tissue had been shown to exert local effects on adjacent cardiac structures. Data regarding the mechanistic link between such measures and left atrial (LA structural/functional remodeling, a clinical hallmark of early stage heart failure (HF and atrial fibrillation (AF incidence, in asymptomatic population remain largely unexplored. Methods: This retrospective analysis includes 356 subjects free from significant valvular disorders, atrial fibrillation, or clinical HF. Regional adipose tissue including pericardial and periaortic fat volumes, interatrial septal (IAS, and left atrioventricular groove (AVG fat thickness were all measured by multidetector computed tomography (MDCT (Aquarius 3D Workstation, TeraRecon, San Mateo, CA, USA. We measured LA volumes, booster performance, reservoir capacity as well as conduit function, and analyzed their association with adiposity measures. Results: All four adiposity measures were positively associated with greater LA volumes (all P < 0.05, while IAS and AVG fat were also related to larger LA kinetic energy and worse reservoir capacity (both P < 0.01. In multivariate models, IAS fat thickness remained independently associated with larger LA volumes, increased LA kinetic energy and ejection force (β-coef: 0.17 & 0.15, both P < 0.05, and impaired LA reservoir and conduit function (β-coef: −0.20 & −0.12, both P < 0.05 after adjusting for clinical variables. Conclusion: Accumulated visceral adiposity, especially interatrial fat depots, was associated with certain LA structural/functional remodeling characterized by impaired LA reservoir and conduit function though augmented kinetic energy and ejection performance. Our data suggested that interatrial fat burden may be associated with certain detrimental LA functions with compensatory LA adaptation in an asymptomatic population.

    The advances in endoscopic instruments have eased the approach to the sellar region through the nasal cavity. We carry out an analysis of the surgical results on 20 patients that underwent surgery for sellar tumours through a transeptal-transphenoidal approach in the last 2 years in our hospital. The average was 45.6 years old, and 75% were females. 30% of cases were pituitary adenomas and another 30% acromegaly, 25% Cushing's disease and 10% prolactinomas. No complications were encountered during surgery being the most common postoperative complications, diabetes insipida in two cases (10%) and CSF leak in one case. At present 2 patients are having hormonal treatment for panhypopituitarism. No patients developed a septal perforation, nasal deformity, epistaxis, meningitis, lip numbness or oronasal fistula. The rest did have good results noith no recurrence and hormonal values back to normal.

    Coronary fistulae and ventricular septal perforation are very rare clinically, and even less caused by cardiac leiomyosarcoma. A case is reported that a 67-year-old female had cardiac leiomyosarcoma with progressive heart failure and coronary fistulae and ventricular septal perforation. This case was special since all ante-mortem examinations and cardiac surgery failed to detect the presence of any abnormal car-diac mass. Therefore, the malignant cardiac tumors could appear in an invasive form without mass and be one of the causes of the coronary fistulae and ventricular septal perforation.

    The prevalence of congenital heart disease in infants with Down syndrome is 40%, compared with 0.3% in children who have normal chromosomes. Atrioventricular and ventricular septal defects are often associated with chromosomal aberrations, such as in trisomy 21, whereas hypertrophic cardiomyopathy is chiefly thought to be secondary to specific gene mutations. We found only one reported case of congenital hypertrophic cardiomyopathy and atrioventricular septal defect in an infant with Down syndrome. Here, we report atrioventricular septal defect, hypertrophic cardiomyopathy, and pulmonary vein stenosis in a neonate with Down syndrome-an apparently unique combination. In addition, we discuss the relevant medical literature.

    Primary septal agenesis (PSA) is a rare brain malformation that can be isolated or part of developmental brain abnormalities (holoprosencephaly, septo-optic dysplasia or cortical malformation). Such associated malformation can be subtle, leading to difficulties in the prenatal management of PSA. Moreover, the neurological prognosis of isolated PSA remains debatable. The aims of the study were to specify the patterns and frequency of brain malformations associated with septal agenesis (SA), to identify the clinical prognosis, and to discuss the aetiology of PSA with the new insights provided by molecular genetics. The study consisted of a 14-year retrospective review of brain MRI in 34 patients having PSA (mean age, 5 years). Chiasm and optic nerves were not evaluated. Post-hydrocephalus SA or incomplete data were excluded. The clinical data were correlated to the MRI patterns. The study disclosed 82.5% associated lesions with MRI (28/34): 11 neuronal migration disorders, 9 holoprosencephalies (HP), 7 pituitary stalk interruptions, 1 corpus callosum partial agenesis; 17.5% (6/34) of cases were apparently isolated PAS. Clinically, the patients had motor dysfunction in 68% (23/34), mental retardation in 65% (22/34), blindness in 24% (8/34), endocrinological defects in 21% (7/34) and epilepsy in 18% (6/34) of cases. Nine percent of patients (3/34) were neurologically normal (including one with scoliosis and two infants younger than 2 years at the last follow-up). Patients with bilateral cortical anomalies and HP (even if mild) had the worst neurological prognosis. A severe motor impairment was present without evidence of hemispheric anomaly in 12% of patients (4/34). Interestingly, the frontal lobes were involved in 90% of cortical anomalies and HP, supporting the malformative aetiology of PSA. PSA rarely appears isolated and severe psychomotor impairment may occur in apparently isolated forms. These unfavourable results should be highlighted and need to be confirmed

    Full Text Available Background. Maze procedure aims at restoring sinus rhythm (SR and atrial contractility (AC. This study evaluated multiple aspects of AC recovery and their relationship with SR regain after ablation. Methods. 122 mitral and fibrillating patients underwent radiofrequency Maze. Rhythm check and echocardiographic control of biatrial contractility were performed at 3, 6, 12, and 24 months postoperatively. A multivariate Cox analysis of risk factors for absence of AC recuperation was applied. Results. At 2-years follow-up, SR was achieved in 79% of patients. SR-AC coexistence increased from 76% until 98%, while biatrial contraction detection augmented from 84 to 98% at late stage. Shorter preoperative arrhythmia duration was the only common predictor of SR-AC restoring, while pulmonary artery pressure (PAP negatively influenced AC recuperation. Early AC restoration favored future freedom from arrhythmia recurrence. Minor LA dimensions correlated with improved future A/E value and vice versa. Right atrial (RA contractility restoring favored better left ventricular (LV performance and volumes. Conclusions. SR and left AC are two interrelated Maze objectives. Factors associated with arrhythmia “chronic state” (PAP and arrhythmia duration are negative predictors of procedural success. Our results suggest an association between postoperative LA dimensions and “kick” restoring and an influence of RA contraction onto LV function.

    Full Text Available "Ball valve thrombus" which is a spherical free floating clot in left atrium is an often quoted, but uncommonly encountered complication in patients with severe mitral stenosis of rheumatic origin, who are in atrial fibrillation. We describe the case of a 31-year-old lady with rheumatic heart disease, severe mitral stenosis and moderately severe aortic stenosis who had undergone closed mitral valvotomy 13 years ago. The patient presented with an episode of non-exertional syncope and breathlessness on exertion of 6 months duration and was in normal sinus rhythm. Echocardiography facilitated ante-mortem diagnosis and prompt institution of surgery was life saving.

    Extracellular matrix (ECM) remodeling increases the vulnerability to atrial fibrillation (AF). Some gene expressions are crucial for the metabolism of ECM. The left atrium plays an important role in maintaining AF.However, most studies investigated only the right atrial tissue. We therefore chose human tissue samples from both the left and right atrial to detect the different gene expressions during structural remodeling in AF. The atrial appendages tissue samples from 24 patients with chronic AF and 12 patients with sinus rhythm were obtained when they were undergoing mitral/aortic valve replacement operation. The mRNA levels of matrix metalloproteinases-9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1), disintegrin, metalloproteases-15, and integrins β1 were determined by reverse transcriptionpolymerase chain reaction (RT-PCR). in AF group, the level of MMP-9 in left atrial appendage (LAA) was increased (P<0.001), while integrin β1 level was decreased (P< 0.05) compared with those expressed in right atrial appendage (RAA) tissue. The levels of disintegrin, metalloproteinases-15, and TIMP-1 genes in the LAA and RAA had no significant differences. The results demonstrated that the gene expressions in the LAA and RAA are different during AF, which implied that the mechanism of atrial structural remodeling in AF is due to multiple sources and is complicated.

    Hemorrhagic fever with renal syndrome (HFRS) is an acute viral disease characterized by fever, hemorrhage and renal failure. Among the various hemorrhagic complications of HFRS, spontaneous rupture of the kidney and perirenal hematoma are very rare findings. We report here on a case of HFRS complicated by massive perirenal hematoma, and this was treated with transcatheter arterial embolization. Hemorrhagic fever with renal syndrome (HFRS) is an acute infectious disease caused by hantavirus. HFRS is clinically characterized by fever, renal failure and hemorrhage in organs such as lung, kidney, spleen and the pituitary gland. Renal medullary hemorrhage is a well-known complication in the kidney, but spontaneous rupture of the kidney and perirenal hematoma in HFRS is rare, and patients showing continuous bleeding and massive perirenal hematoma have often been surgically treated. We report here on a case of HFRS complicated by massive perirenal hematoma, and the patient was treated with transcatheter arterial embolization. In summary, spontaneous rupture of the kidney and perirenal hematoma is a rare complication of HFRS. We report here on a case of HFRS that caused massive perirenal hematoma, and this was treated with superselective renal artery embolization.

    2016-01-01

    Full Text Available Background. Large craniotomy for acute subdural hematoma is sometimes too invasive. We report good outcomes for two cases of neuroendoscopic evacuation of hematoma and contusion by 1 burr hole surgery. Case Presentation. Both patients arrived by ambulance at our hospital with disturbed consciousness after falling. Case 1 was an 81-year-old man who took antiplatelet drugs for brain infarction. Case 2 was a 73-year-old alcoholic woman. CT scanning showed acute subdural hematoma and frontal contusion in both cases. In the acute stage, glycerol was administered to reduce edema; CTs after 48 and 72 hours showed an increase of subdural hematoma and massive contusion of the frontal lobe. Disturbed consciousness steadily deteriorated. The subdural hematoma and contusion were removed as soon as possible by neuroendoscopy under local anesthesia, because neither patient was a good candidate for large craniotomy considering age and past history. 40%~70% of the hematoma was removed, and the consciousness level improved. Conclusion. Neuroendoscopic removal of acute subdural hematoma and contusion has advantages and disadvantages. For patients with underlying medical issues or other risk factors, it is likely to be effective.

    2009-03-01

    Full Text Available OBJECTIVE: Mitral valve surgery can be performed through the trans-atrial or the trans-septal approach. Although the trans-atrial is the preferred method, the trans-septal approach has also been used recently and has a particular value in beating-heart mitral valve surgery. Herein we report our experience with beating-heart mitral valve surgery via trans-septal approach, and discuss its advantages and pitfalls. METHODS: Between 2000 and 2007, 214 consecutive patients were operated upon utilizing beating heart technique for mitral valve surgery. The operation was performed via transseptal approach with the aorta unclamped, the heart beating, with normal electrocardiogram and in sinus rhythm. RESULTS: Mean age was 56.03 ± 13.93 years (range: 19-86 years; median: 56 years. There were 131 (61.2% males and 83 (38.8% females. Of the prostheses used, 108 (50.5% were biological, and 39 (18.2% were mechanical. Mitral repairs were performed in 67 (31.3% patients. Mean hospital stay was 17.4 ± 20.0 days (range: 3-135 days; median: 11 days. Intra-aortic balloon pump (IABP utilization was required in 12 (5.6% of 214 patients. One-month mortality was 7.4%, and re-operation for bleeding was needed in 15 (7% patients. CONCLUSIONS: Beating-heart mitral valve surgery is an option for myocardial protection in patients undergoing mitral valve surgery. This technique is facilitated by the trans-septal approach due to reduced aortic insufficiency and improved visualization of the mitral apparatus.OBJETIVO: A cirurgia da valva mitral pode ser feita via transatrial ou transeptal.

    OBJECTIVE There is little information on the frequency of symptomatic epidural hematomas after the implantation of paddle spinal cord stimulators (SCSs) in the thoracic spine. The purpose of this paper is to provide this metric and compare it to the frequency of symptomatic epidural hematomas for all other thoracic laminectomies combined. METHODS This study involved retrospectively analyzing the experience of a single surgeon in a consecutive series of patients who underwent the implantation of a thoracic paddle SCS with respect to the occurrence of a symptomatic epidural hematoma. For comparison, the occurrence of a symptomatic epidural hematoma in non-SCS thoracic laminectomies done during the same period of time was determined. RESULTS One hundred fifty-four thoracic paddle SCSs were implanted between May 2002 and February 2015. Despite perfect hemostasis and no preoperative risk factors, 4 of 154 patients (2.60%) developed postoperative lower-extremity weakness caused by an epidural hematoma. There were no other causes of a neurological deficit. In 3 of the 4 patients, the symptoms were delayed. Over the same time period, only 1 of 119 patients (0.84%) developed a postoperative motor deficit from a symptomatic epidural hematoma after a non-SCS laminectomy. CONCLUSIONS The occurrence of epidural hematomas after thoracic paddle SCS implantation may be underreported. Suggestions are given to decrease its incidence. It seems paradoxical that an epidural hematoma occurred 3 times more often after small SCS thoracic laminectomies than after larger non-SCS thoracic laminectomies. If confirmed by future studies, this finding may suggest that the intrusion of instruments into a confined epidural sublaminar space or the presence of a paddle and a hematoma in this restricted space may account for this differential.

    PURPOSE: This study aimed to assess the usefulness of Danish patient registers for epidemiological studies of subdural hematoma (SDH) and to describe clinical characteristics of validated cases. METHODS: Using a patient register covering a geographically defined area in Denmark, we retrieved...... moderate for patients recorded under code I620 (62%). cSDH represented 57% of verified cases, and aSDH the remaining 43%. cSDH differed markedly from aSDH with regard to a number of clinical characteristics, including a much lower mortality (OR 0.2, 95%CI 0.1-0.3). However, preadmission antithrombotic drug...... hospital contacts recorded under SDH International Classification of Diseases version 10 codes S065 and I620 in 2000-2012. Neurosurgeons reviewed medical records of all potential cases. Based on brain scan results, verified cases were classified by SDH type (chronic SDH (cSDH) or acute SDH (aSDH)). Thirty...

    Full Text Available The surgical option to evacuate an intracranial extradural hematoma (EDH was postponed in a 2-year-old female child who appeared fully alert and active after a brief spell of unconsciousness following a fall from height. The child was received, with a swelling on and around the right parietal eminence, by the emergency staff just half an hour after the time of injury. The immediate X-ray skull and first computed tomography (CT scan head showed a parietal bone fracture, EDH, and cephalhematoma. However, follow-up CT scan head after about 4΍ h revealed the dramatic absence of EDH but increased size and bogginess of cephalhematoma. The EDH had transported into subgaleal space resulting in a decompression of intracranial compartment in <5 h, thereby preventing surgical intervention but necessitating monitoring, though there was no back flow intracranially.

    An 86-year-old woman was scheduled to undergo aortic valve replacement and coronary artery bypass graft. On postoperative day 3, she developed sudden-onset neck pain followed by weakness in the right arm. Her symptoms worsened with time, and she developed paraplegia. At 60 h after the first complaint, spontaneous spinal epidural hematoma (SSEH) from C2 to C6 with spinal cord compression was diagnosed from a magnetic resonance image of the cervical region. We decided on conservative therapy because operative recovery was impossible. Delayed diagnosis led to grievous results in the present case. When neurological abnormalities follow neck or back pain after open heart surgery, SSEH must be considered in the differential diagnosis. Further, if it is suspected, early cervical computed tomography/magnetic resonance imaging and surgery should be considered.

    A woman, aged 84 years, presented to our emergency department with posteriorly radiating chest pain that began following dinner. She reported no change in bowel habits, hematochezia, or melena. She had previous peptic ulcer disease and a long-standing history of gastroesophageal reflux disease. Her medications included acetylsalicylic acid and rabeprazole. Electrocardiogram and troponin analyses were negative for ischemic heart disease. The emergency physician suspected an aortic dissection, and computed tomography (CT) chest and abdomen scans were performed with and without IV and oral contrast. The aorta was normal and the noncontrast images demonstrated a hyperdense mass (not shown) that did not enhance consistent with a large intramural hematoma extending from the upper esophagus (level of T2 vertebral body) to the fundus of the stomach (Figures 1A and B).

    Foreign accent syndrome (FAS), a rare disorder characterized by the emergence of a new accent perceived as foreign by listeners, is usually reported with left brain damage. We here report the case of a 28-year-old native Brazilian who appeared, to the examiner, to show a North American accent during recovery from Broca's aphasia. The lesion was due to a frontal hematoma. Without referring specifically to speech, we asked 10 independent observers to comment on a videotape of the patient's interview. Seven reported that the patient had a foreign accent, while 3 simply noted a 'strange' accent. The observers did not agree on the origin of the accent, 5 identifying it as Spanish, 1 as German, and 1 as south Brazilian. These findings suggest that FAS is not due to the acquisition of a specific foreign accent, but to impairment of the suprasegmental linguistic abilities (tone, accent, pauses, rhythm, and vocal stress) that make it possible to distinguish native language.

    Full Text Available Abstract Background Survival in colorectal cancer may correlate with the degree of systemic inflammatory response to the tumour. Atrial fibrillation may be regarded as an inflammatory complication. We aimed to determine if atrial fibrillation is a prognostic factor in colorectal cancer. Patients and methods A prospective colorectal cancer patient database was cross-referenced with the hospital clinical-coding database to identify patients who had underwent colorectal cancer surgery and were in atrial fibrillation pre- or postoperatively. Results A total of 175 patients underwent surgery for colorectal cancer over a two-year period. Of these, 13 patients had atrial fibrillation pre- or postoperatively. Atrial fibrillation correlated with worse two-year survival (p = 0.04; log-rank test. However, in a Cox regression analysis, atrial fibrillation was not significantly associated with survival. Conclusion The presence or development of atrial fibrillation in patients undergoing surgery for colorectal cancer is associated with worse overall survival, however it was not found to be an independent factor in multivariate analysis.

    An 8-year-old boy developed vomiting and severe headache following minor head trauma. A CT scan of the head demonstrated a lytic lesion of the skull and adjacent epidural hematoma. Surgical evacuation and removal of the skull lesion and hematoma were carried out, and pathologic evaluation resulted in a diagnosis of Langerhans' cell histiocytosis (LCH). Epidural involvement of Langerhans' cell histiocytosis is very rare, and we report the first case of LCH presenting as an intracranial epidural hematoma. (orig.)

    Full Text Available Neonatal scrotal hematoma is a rare genitourinary emergency. Some cases have underlining aetiologic factors such as testicular torsion, adrenal hemorrhage, or birth trauma, and others are idiopathic. Previously, immediate scrotal exploration was considered imperative for diagnosis and treatment. With good imaging techniques, some patients are managed nonoperatively. We report a case of idiopathic scrotal hematoma in a neonate. He was managed conservatively with clinical and radiological follow-up. There was complete resolution of hematoma within two months, thus, avoiding unnecessary exploration.

    We describe a case involving spontaneous retroperitoneal hematoma complicating a normal delivery in a context of a Disseminated Intravascular Coagulation (DIVC) at the end of the pregnancy. Given the defaced symptomatology, an abdomino-pelvic scanner and an examination with a general anaesthesia made it possible to diagnose and to monitor the hematoma in intensive care. The correction of the hemostasis troubles and of the anemia, without another invasive intervention, allowed a return to home at the eighth day. The pathophysiological mechanisms underlying development and practicable treatments of this post-partum hematoma are discussed.

    Epidural hematoma is a rare cause of spinal cord compression, which usually provokes severe neurological deficits. It is presumed to originate from venous or, more probably, arterial bleeding. Thrombocytopenia and other disorders of coagulation may precipitate the onset of epidural hematoma and facilitate the evolution of the disease. We report the case of a patient suffering from a non-Hodgkin's lymphoma with severe thrombocytopenia during a MACOP-B schedule, who presented with a spontaneous cervical epidural hematoma. We discuss the etiopathological aspects, diagnosis, and treatment of this rare cause of acute cervical spinal cord compression.

We discuss an unusual case of an elderly woman who presented with spontaneous spinal subdural hematoma and developed massive rebleeding on the third day following initial evacuation of hematoma. This case illustrates that a patient with routine normal coagulation profile and adequate hemostasis can still harbor platelet dysfunction (in present case due to polycythemia and later on can manifest as rebleeding and neurological deterioration.

    2013-03-01

    Atrial fibrillation (AF) is the most common significant cardiac rhythm disorder, and its prevalence is increasing worldwide. Atrial fibrillation confers a fivefold increased risk of stroke, and these strokes are associated with significant mortality and disability. The vitamin K antagonist, warfarin, has been the mainstay of anticoagulant therapy for patients with AF, reducing the risk of stroke by 65%. Despite its efficacy, warfarin remains underused in clinical practice because of its variable dose response, diet and medication interactions, and need for frequent monitoring. Stroke prevention in AF has entered an exciting therapeutic era with new classes of targeted anticoagulants that avoid the many pitfalls of the vitamin K antagonists. Dabigatran, an oral thrombin inhibitor, and the factor Xa inhibitors, rivaroxaban and apixaban, have demonstrated efficacy for stroke prevention and a reduced risk of intracranial hemorrhage relative to warfarin. Translating the efficacy of clinical trials into effective use of these novel agents in clinical practice will require an understanding of their pharmacokinetic profiles, dose selection, and management in select clinical situations.

    To bring attention to the MR imaging appearance of epidural hematoma (EDH) in the lumbar spine as a small mass often associated with disk herniation or an acute event. This paper will show our experience with this entity and describe criteria for its MR imaging appearance. Design and patients. Thirteen cases of prospectively diagnosed EDH of the lumbar spine were compared with 12 cases of prospectively diagnosed prominent epidural extrusion. Our criteria were retrospectively evaluated by the two authors for their presence or absence in each case. The chi-square test for nominal data was applied. MR imaging criteria utilized to distinguish EDH from disk herniation at our institution include: (1) signal different from disk, (2) high signal on T1-weighted images, either centrally or peripherally, (3) teardrop- or egg-shaped mass, in the sagittal plane, (4) size greater than half the vertebral body height in a craniocaudal dimension, (5) primarily retrosomatic epidural location, (6) plasticity - the mass is seen to conform closely to the contours of bone (e.g., in the lateral recess), (7) little or no disk space narrowing unless associated with disc herniation. Chi-square analysis demonstrated each criterion to significantly differentiate between EDH and extrusion. Only six of 13 EDH cases went to surgery in spite of their relatively large size. Two of six patients were diagnosed as having epidural clot consistent with hematoma at the time of surgery. The four patients who were not diagnosed at surgery revealed only small disk herniations or fragments of disk. The occurrence of EDH is more frequent than previously suspected. Spontaneous EDH is frequently associated with disk herniation and acute events such as sneezing or coughing. Most cases of spontaneous EDH will resolve prior to surgery with only the minority becoming chronic in order to be seen at surgery as an encapsulated mass. MR imaging can reliably identify EDH and distinguish between EDH and large disk

    Various sequelae of alcohol septal ablation for hypertrophic obstructive cardiomyopathy have been reported. Of note, some cases of cardiac tamponade after alcohol septal ablation cannot be well explained. We describe the case of a 78-year-old woman with hypertrophic obstructive cardiomyopathy in whom cardiac tamponade developed one hour after alcohol septal ablation, probably unrelated to mechanical trauma. At that time, we noted a substantial difference in the red blood cell-to-white blood cell ratio between the pericardial effusion (1,957.4) and the peripheral blood (728.3). In addition to presenting the patient's case, we speculate that a possible mechanism for acute tamponade--alcohol-induced changes in microvascular permeability--is a reasonable explanation for cases of alcohol septal ablation that are complicated by otherwise-unexplainable massive pericardial effusions.

    Objective Mechanisms of pulmonary vein isolation (PVI) for atrial fibrillation remain controversy.This study aimed to investigate the impact of PVI on vagal modulation to atria.Methods Eighteen adult mongrel dogs under general anesthesia were randomly divided into two groups.Bilateral cervical sympathovagal trunks were decentralized and sympathetic effects was blocked by metoprolol administration.Atrial electrical remodeling (AER) was established by rapid right atrial pacing at the rate of 600 bpm for 30 minutes.PVI was performed in group A.Atrial effective refractory period (ERP),vulnerability window (VW) of atrial fibrillation,and sinus rhythm cycle length (SCL) were measured at baseline and during vagal stimulation before and after atrial rapid pacing with and without PVI at fight atrial appendage (RAA),left atrial appendage (LAA),distal coronary sinus (CSd) and proximal coronary sinus (CSp).Results (1) Effects of PVI on vagal modulation:Shortening of SCL during vagal stimulation decreased significantly after PVI compared with that before PVI in group A (P<0.001).Shortening of ERP during vagal stimulation decreaseed significantly after PVI compared with that before PVI (P<0.05).VW of atrial fibrillation during vagal stimulation decreased significantly after PVI compared with that before PVI (P<0.05).(2) Effects of PVI on AER:shortening of ERP before and after atrial rapid pacing increased significantly at baseline and vagal stimulation in group B compared with that in group A (P<0.05).VW during vagal stimulation increased significantly after atrial rapid pacing in group B (P<0.05).Conclusion PVI attenuates the vagal modulation to the atria,thereby decreases the susceptibility to atrial fibrillation mediated by vagal activity.PVI releases AER,which maybe contributes to the vagal denervation.Our study indicates that PVI not only can eradicate triggered foci but also modify substrates for AF.(J Geriatr Cardiol 2008;5:28-32)

    Full Text Available Abstract Introduction Vascular complications related to cup-fixating screws penetrating the medial acetabular wall during total hip arthroplasty are not uncommon but rarely are associated with serious adverse events in the late post-operative period. Case presentation We present the case of a 77-year-old Japanese woman who developed progressive extensive bone resorption and large hematoma in the acetabulum 13 years after total hip arthroplasty. On admission to our hospital, she was on oral warfarin (1.5mg/day for atrial fibrillation. About 5 months after the initiation of anticoagulant therapy, she suffered a major fall followed by massive subcutaneous and pelvic girdle bleeding, predominantly on the medial side of the right thigh, but a fracture or damage of total hip arthroplasty was not evident on an emergency orthopedic evaluation. One year after the accident, a routine follow-up examination showed an asymptomatic osteolytic lesion in the acetabulum on the right pelvis, and 2 years later our patient noticed progressive pain in her right hip during walking. A large osteolytic lesion was noted in the right acetabulum on a plain radiograph. On high-resolution computed tomography and magnetic resonance imaging, a huge granulomatous lesion in the acetabulum was suggestive of chronic hematoma in intrapelvic and extrapelvic gluteal regions. A closer computed tomography examination showed that one of the screws used for fixation of the acetabular component in the total hip arthroplasty had penetrated the acetabular bone and had reached the pelvic cavity. Surgery was performed in a single session by means of two approaches: anterior midline transperitoneal address to resect the low-density mass lesion followed by posterolateral acetabular implant re-settlement. Conclusions Though rare, total hip arthroplasty-related late vascular complications could be serious and potentially affect the limb and quality of life.

    Core-needle biopsy remains essential for diagnosis of cirrhosis; however, evaluation of fibrosis in such biopsies is often challenging due to the fragmented nature of cirrhotic liver specimens. It is also common to see portions of liver capsules present in the biopsy which adds to the diagnostic challenge. The distinction between capsular/subcapsular fibrous tissue and septal fibrosis is critical to avoid potential overstaging of liver fibrosis. We compared the differential immunostaining in liver capsular and septal areas for collagens III, IV, V, VI, vitronectin, laminin, Orcein, and Trichrome in 15 whole sections of explanted cirrhotic livers and 5 simulated liver biopsies. Collagens III, IV, V, VI, Trichrome, and Orcein show distinct staining patterns in capsular fibrous tissue and septal fibrosis. Collagen IV shows strong diffuse septal staining and consistently weak to negative capsular staining. Collagens III and VI stain similar to IV for septal fibrosis, whereas collagen V, Trichrome, and Orcein show strong staining in both areas. Collagen IV, possibly with III or VI in addition to the routine Trichrome and hematoxylin and eosin stain, is useful in differentiating capsular fibrous tissue from septal fibrosis on challenging and fragmented liver biopsies.

    Full Text Available OBJECTIVE: Ventricular septal defects resulting from post-traumatic cardiac injury are very rare. Percutaneous closure has emerged as a method for treating this disorder. We wish to report our experience in three patients who underwent percutaneous closure of a post-traumatic ventricular septal defect with a patent ductus arteriosus occluder. METHODS: We treated three patients with post-traumatic ventricular septal defects caused by stab wounds with knives. After the heart wound was repaired, patient examinations revealed ventricular septal defects with pulmonary/systemic flow ratios (Qp/Qs of over 1.7. The post-traumatic ventricular septal defects were closed percutaneously with a patent ductus arteriosus occluder (Lifetech Scientific (Shenzhen Co., LTD, Guangdong, China utilizing standard techniques. RESULTS: Post-operative transthoracic echocardiography revealed no residual left-to-right shunt and indicated normal ventricular function. In addition, 320-slice computerized tomography showed that the occluder was well placed and exhibited normal morphology. CONCLUSION: Our experiences indicate that closure of a post-traumatic ventricular septal defect using a patent ductus arteriosus occluder is feasible, safe, and effective.

    From July 2003 to July 2009, 15 cases of subdural hematoma with swirl signs were treated in our hospital and their clinical data were retrospectively analysed.The mortality was compared between these patients and those with typical acute subdural hematoma who were treated at the same time in our hospital. Among the 15 cases, full recovery was achieved in 4 cases, slight disability in 2, gave disability in 2 and death in 7 (46.7%). The mortality of these patients was conspicuously higher than that of typical subdural hematoma (14/83, 16.9%, P<0.01). Subdural hematoma with swirl signs is often suggestive of hazardous pathogenetic condition and early diagnosis and prompt surgical intervention is essential to reduce mortality.

    Clinical outcomes are positively associated with hematoma absorption. The monocyte-macrophage scavenger receptor, CD163, plays an important role in the metabolism of hemoglobin, and a soluble form of CD163 is present in plasma and other tissue lfuids;therefore, we speculated that serum CD163 affects hematoma absorption after intracerebral hemorrhage. Patients with intracerebral hemorrhage were divided into high-and low-level groups according to the average CD163 level (1,977.79 ± 832.91 ng/mL). Compared with the high-level group, the low-level group had a signiifcantly slower hematoma absorption rate, and signiifcantly increased National Institutes of Health Stroke Scale scores and modiifed Rankin Scale scores. These results suggest that CD163 promotes hematoma absorption and the recovery of neurological function in patients with intracerebral hemorrhage.

    We report on a patient with an unusual, slowly enlarging hematoma of the left buttock. A 62-year-old man presented with a 6-year history of an enlarging mass of the left buttock. He had first noted the mass 6 years earlier and had had sciatica of the left lower limb for the last 2 months. He denied any history of antecedent trauma. The lesion extended over 3 gluteal muscles (the gluteus medius, gluteus minimus, and piriformis). On microscopic examination, the lesion showed typical signs of chronic expanding hematoma. The sciatica was relieved after surgical removal of the lesion. The lesion had not recurred at the last follow-up 4 years after the operation. The present case suggested that chronic expanding hematoma can extend into multiple muscles due, perhaps, to long-term growth and the anatomical and functional conditions of the affected muscles. Our case also suggests that chronic expanding hematoma can be a cause of piriformis syndrome.

    Full Text Available Alcohol abuse is associated with both potentiating and antagonizing hemostatic states. Liver cirrhosis is an independent causal factor for many bleeding complications. The long-term effects of alcohol abuse coupled with advanced liver cirrhosis are additive in favor of bleeding. We report the case of a patient with a history of alcohol abuse who presented with liver cirrhosis and nontraumatic muscle hematoma diagnosed as a spontaneous hematoma of the gastrocnemius muscle. He was managed conservatively with infusions of fresh frozen plasma and platelets, which resulted in resolution of the hematoma. The pathogenesis of ‘spontaneous' muscle hematoma remains anecdotal, but since it is reported in patients on anticoagulant therapy or with hemostatic disorders, it is hypothetically related to severely deranged coagulation. Here we review the relevant literature pertaining to the pathogenesis, presentation and treatment options available for treating this often fatal complication of bleeding diatheses.

    Full Text Available Traumatic retroclival hematomas are uncommon lesions usually associated with significant trauma. Majority of the reported hematomas are epidural; and in the pediatric population. Retroclival acute subdural hematomas (RSDH are very rare, with only two previous cases reported in English literature. An 18-year-old man presented with headache and no deficits following an accident. Computer tomography (CT scan and magnetic resonance imaging (MRI showed an acute RSDH extending into the spinal subdural space. He developed bilateral sixth nerve palsies, with symptoms of raised intracranial pressure within the next 24 hours. He underwent evacuation of hematoma with a good outcome. Another 19-year-old man presented with neck pain following a fall from a moving bus. He had no neurological deficits. CT scan showed a RSDH extending across the craniovertebral junction. He was managed conservatively with good outcome.

    Full Text Available A wireless powered implantable atrial defibrillator consisting of a battery driven hand-held radio frequency (RF power transmitter (ex vivo and a passive (battery free implantable power receiver (in vivo that enables measurement of the intracardiac impedance (ICI during internal atrial defibrillation is reported. The architecture is designed to operate in two modes: Cardiac sense mode (power-up, measure the impedance of the cardiac substrate and communicate data to the ex vivo power transmitter and cardiac shock mode (delivery of a synchronised very low tilt rectilinear electrical shock waveform. An initial prototype was implemented and tested. In low-power (sense mode, >5 W was delivered across a 2.5 cm air-skin gap to facilitate measurement of the impedance of the cardiac substrate. In high-power (shock mode, >180 W (delivered as a 12 ms monophasic very-low-tilt-rectilinear (M-VLTR or as a 12 ms biphasic very-low-tilt-rectilinear (B-VLTR chronosymmetric (6ms/6ms amplitude asymmetric (negative phase at 50% magnitude shock was reliably and repeatedly delivered across the same interface; with >47% DC-to-DC (direct current to direct current power transfer efficiency at a switching frequency of 185 kHz achieved. In an initial trial of the RF architecture developed, 30 patients with AF were randomised to therapy with an RF generated M-VLTR or B-VLTR shock using a step-up voltage protocol (50–300 V. Mean energy for successful cardioversion was 8.51 J ± 3.16 J. Subsequent analysis revealed that all patients who cardioverted exhibited a significant decrease in ICI between the first and third shocks (5.00 Ω (SD(σ = 1.62 Ω, p < 0.01 while spectral analysis across frequency also revealed a significant variation in the impedance-amplitude-spectrum-area (IAMSA within the same patient group (|∆(IAMSAS1-IAMSAS3[1 Hz − 20 kHz] = 20.82 Ω-Hz (SD(σ = 10.77 Ω-Hz, p < 0.01; both trends being absent in all patients that failed to cardiovert

    Full Text Available The increasing prevalence of stroke, with an estimated annual cost of $71.5 billion, has made it a major health problem that increases disability and death, particularly in patients with atrial fibrillation. Although advanced age and atrial fibrillation are recognized as strong risk factors for stroke, the basis for this susceptibility are not well defined. Aging or associated diseases are accompanied by changes in rheostatic, humoral, metabolic and hemodynamic factors that may contribute more to stroke predisposition than rhythm abnormality alone. Several thromboembolism-predisposing clinical characteristics and serum biomarkers with prognostic significance have been identified in patients with atrial fibrillation. Although anticoagulation decreases the risk of thromboembolism, management in the elderly remains complex due to major concerns about bleeding. New anticoagulants and nonpharmacologic strategies are helpful to reduce the risk of bleeding, particularly in older-elderly patients. Herein, we review the pathogenesis and management of select issues of thromboembolism in the elderly with atrial fibrillation.

    2015-12-01

    Full Text Available Atrial fibrillation is the most common perioperative cardiac arrhythmia. Sympathetic overactivity, inflammatory state and oxidative stress are important contributors to the genesis of postoperative atrial fibrillation. Advancing age and mitral valve disease along with left atrial size are important parameters in noted in multivariate prediction model. Genetic predisposition has also been noted. Preventive strategies tried include beta blockers, statins, posterior pericardiotomy, carperitide infusion and thoracic epidural analgesia. Treatment options include rate and rhythm control along with anticoagulation if it persists more than 48 hours with high CHADS2 score. Some of the therapeutic modalities which have been found to be NOT useful in preventing post operative atrial fibrillation are dexamethasone, magnesium infusion and concomitant pulmonary vein isolation.

    BACKGROUND: The aim of this study was to test the hypothesis that alcohol consumption, both observational (self-reported) and estimated by genetic instruments, is associated with a risk of atrial fibrillation and to determine whether people with high cardiovascular risk are more sensitive towards...... register. As a measure of alcohol exposure, both self-reported consumption and genetic variations in alcohol metabolizing genes (ADH1B/ADH1C) were used as instrumental variables. The endpoint was admission to hospital for atrial fibrillation as recorded in a validated hospital register. RESULTS: A total...... of 3493 cases of atrial fibrillation occurred during follow-up. High alcohol consumption was associated with a risk of atrial fibrillation among men, but not among women. Among the men who drank 28-35 and 35+ drinks/week, the hazards ratios were 1.40 (95% confidence interval 1.09-1.80) and 1.62 (95...

    The course of cardiac rehabilitation is often altered due to episodes of paroxysmal, predominantly postoperative atrial fibrillation. In symptomatic patients, a TEE-guided cardioversion - preferential DC shock - is indicated. In patients with persistent / permanent atrial fibrillation, a heart rate up to 110 / min and 170 / min at rest and during physical activity should, respectively, be tolerated. Therefore, training should not be quitted by heart rate but rather by load. The antithrombotic management is in addition a great task in treating patients with atrial fibrillation. With the exception of patients with a CHA2DS2-VASc-Score < 1, oral anticoagulation is indicated. Atrial fibrillation has little impact on social aspects, whereas the underlying heart disease and drug treatment (oral anticoagulation) has an important impact.

    2014-01-01

    Full Text Available Background: Subgaleal hematomas frequently occur in children after head trauma and extend over the cranial sutures. Although conservative treatment suffices in most cases, surgical removal of a subgaleal hematoma is indicated when the patient presents with anemia and headache associated with its progressive enlargement. Case Description: We present the case of a 7-year-old boy who was medicated with warfarin and aspirin due to a hypoplastic left ventricle and fell from a rock wherein he hit his head in the frontal region. Although a computed tomography scan of the head revealed no intracranial lesion, an extracranial hematoma was found to extend over the cranial sutures, leading to the diagnosis of subgaleal hematoma. The hematoma continued to grow gradually despite the cessation of warfarin and aspirin therapy immediately after the head trauma. Since the patient′s headache and anemia were progressing as the hematoma enlarged, removal of the hematoma was performed 3 days after admission. Endoscopic hematoma removal was planned to enable accurate coagulation of the sites of bleeding and removal of the maximal amount of hematoma through minimal incision. The hematoma was completely removed, and the patient′s postoperative course was excellent with alleviation of both the anemia and the headache. No sign of hematoma recurrence could be detected during 2 years follow-up. Conclusion: An angled endoscope can allow visualization of the deep subgaleal space, and this technique enabled direct visualization of the bleeding sites and accurate coagulation to prevent recurrence of hematoma. Endoscopic techniques, such as minimally invasive techniques, can allow sufficient removal of subgaleal hematoma with minimal morbidity, especially in patients such as ours.

    A newborn presented on day 15 of life with an epidural hematoma, extending through a diastatic sutura squamosa in an external cephalhematoma. There was no skull fracture. The cephalhematoma was punctured twice with 24-h interval, reducing both the cephalhematoma and the epidural component. In the absence of neurological signs or symptoms, aspirating a cephalhematoma to evacuate the communicating epidural hematoma in a newborn infant may avoid more invasive surgical intervention.

    1994-04-01

    A 9-year-old boy had been diagnosed at the age of 9 months as having a cerebellar medulloblastoma and had received 40 Gy of radiation therapy to the brain after removal of the tumor. Cerebral angiography at the time of initial diagnosis did not show any evidence of occlusive disease involving the internal carotid circulation. At the age of 6 years, the patient developed generalized seizures. On examination, he was drowsy and had right hemiparesis. CT scan demonstrated a low-density area in the left frontal lobe. Cerebral angiography showed a marked narrowing of the bilateral internal carotid arteries with moyamoya vessels. The patient was treated medically with aspirin (100 mg/day) and anticonvulsants. His neurological deficits improved gradually. At the age of 8 years, there was no recurrence of the tumor although a slight left subdural hematoma was seen on CT scan. On August 10, 1993, at the age of 9 years, he was admitted for treatment of a developing subdural hematoma. MRI showed a chronic subdural hematoma with thick outer and inner membranes. Cerebral angiography showed occlusion of the left internal carotid artery which fed the right frontal lobe through moyamoya vessels, marked narrowing of the right internal carotid artery distal to the ophthalmic artery, moyamoya vessels at the base, and cortical revascularization througth the ophthalmic, posterior cerebral and middle meningeal arteries. Trepanation and aspiration of the hematoma were performed. The outer membrane of the hematoma was about 2 mm thick and the hematoma cavity was filled with a partially organized hematoma. In this case, we speculate that development of the chronic subdural hematoma involved the following factors: (1) transdural external-internal carotid anastomosis after radiation-induced cerebrovasculopathy; (2) repeated mild head trauma due to gait disturbance after removal of the cerebellar tumor; and (3) administration of acetylsalicylic acid.

    2003-01-01

    Objective To study the effect of endoscopic-assisted keyhole operation (EAKO) on treating hypertensive intracranial hematomas and the value of our patent dissector appli ed during the operation.Methods A total of 25 patients with hypertensive intracranial hematomas underwent endos copic-assisted keyhole evacuation, during which, the viewing dissector, which h ad recently achieved national patent, was connected to the tip of endoscope and used to help dissect hematomas. The outcome of this procedure were compared wit h those of 22 comparable cases undergone conventional surgical treatment (large or smaller craniotomy). The items for comparison included the volum e of remaining hematoma, the duration of operation, postsurgical Glasgow Coma Sc ale (GCS) and Glasgow Outcome Scale (GOS).Results Remaining hematoma was ascertained 48 h after operation with the use of computerized tomography (CT) scans. In the case of EAKO, nearly complete evacuation (>84%) was achieved in 21 cases; GCS was evaluated at 7 d postsurgery result ing in GCS >12 in 9 patients, GCS 9-12 in 12 patients and GCS <9 in 4 patients. The follow-up period ranged from 6 to 21 mon. GOS was estimated at half a year and good recovery rate as defined by GOS was assigned to 76% of the EAKO pa tients. There are significant differences in the volumes of remaining hematomas and the duration of operation between the EAKO and craniotomy group (P<0.0 5). In addition, better clinical outcomes were obtained in EAKO. Conclusion EAKO has the advantage of being minimally invasive, improving surgical results and the prognosis of hypertensive intracranial hematoma patients. We conclude th at keyhole operation is a safe, effective alternative for removal of hypertensiv e intracranial hematoma, particularly during acute stages.
