    Microbiological and pathological data from a case of equine valvular endocarditis are reported. Limited information is available on the pathogenic potential of equine Actinobacillus species as several strains originate from apparently healthy horses. After the establishment of two subspecies within...... this species, this seems to be the first report of an etiological association between A. equuli subsp. equuli and equine endocarditis. Furthermore, new information on some phenotypical characteristics of this subspecies are reported, compared to previous findings...

    A variety of microorganisms can cause infective endocarditis (IE) in patients with native valves. Staphylococci and streptococci are most common in community-acquired IE; staphylococci are most common in nosocomial IE. Microbiology of prosthetic valve endocarditis (PVE) depends on timing. Early-onset PVE (ie, 60 days or fewer postsurgery) typically is nosocomial, with Staphylococcus aureus infection being most common. Intermediate-onset PVE (ie, 60 to 365 days postsurgery) typically involves a mix of nosocomial and non-nosocomial organisms. PVE that develops more than 1 year after surgery has microbiology similar to that of native valve endocarditis. Fever is the most common symptom; others include dyspnea, pleuritic pain, anorexia, and myalgias. The Modified Duke Criteria is the standard for diagnosis, with blood cultures being the most important test. If patients are in stable condition, three sets of blood cultures should be obtained more than 6 hours apart and from separate sites before starting antibiotics. Echocardiography aids in diagnosis and can identify conditions best managed with surgery. For empiric therapy for native valve IE, most patients should receive vancomycin. For PVE, vancomycin and gentamicin should be prescribed, plus cefepime or an antipseudomonal carbapenem. Treatment typically continues for 6 weeks after blood culture results are negative.

    Full Text Available We report a case of a 74-year-old female, with a mitral heart valve, who presented with pain and blurred vision in the right eye for 2 days. Her visual acuity was light perception (LP in the right eye and 20/40 in the left eye. Slit lamp examination showed corneal edema and hypopyon, and a view of the right fundus was impossible. Echography showed vitreous condensation. One day after presentation, the patient developed acute lung edema requiring hospitalization, so she was not submitted to vitreous tap and intravitreal treatment. The cardiac and systemic evaluations revealed a mitral endocarditis secondary to Enterococcus faecalis. The patient improved systemically with treatment with gentamicin, vancomycin, and linezolid. Her visual acuity remained as no LP, and her intraocular pressure (IOP has been controlled with brimonidine bid despite developing a total cataract with 360° posterior synechia. A cardiac source for endogenous endophthalmitis should be considered in the presence of a prosthetic cardiac valve. The treatment and followup must be made in cooperation with a cardiologist specialist, but the ophthalmologist can play a key role in the diagnosis.

    Valvular heart diseases in Africa affect mainly children and young adults and are a result of rheumatic fever. Rheumatic fever is a preventable disease, but in Africa the combination of a lack of resources, lack of infrastructure, political, social and economic instability, poverty, overcrowding, malnutrition and lack of political will contributes to the persistence of a high burden of rheumatic fever, rheumatic valvular heart diseases and infective endocarditis. Combating and eradicating rheumatic fever and rheumatic heart diseases requires economic development and implementation of best practices of primary and secondary prevention measures. The barriers to achieving this goal in Africa are numerous, but not insurmountable.

    The mechanisms that underlie valvular inflammation in streptococcus-induced infective endocarditis (IE) remain unclear. We previously demonstrated that streptococcal glucosyltransferases (GTFs) can activate human heart valvular interstitial cells (VIC) to secrete interleukin-6 (IL-6), a cytokine involved in T helper 17 (Th17) cell differentiation. Here, we tested the hypothesis that activated VIC can enhance neutrophil infiltration through sustained IL-17 production, leading to valvular damage. To monitor cytokine and chemokine production, leukocyte recruitment, and the induction or expansion of CD4+ CD45RA− CD25− CCR6+ Th17 cells, primary human VIC were cultured in vitro and activated by GTFs. Serum cytokine levels were measured using an enzyme-linked immunosorbent assay (ELISA), and neutrophils and Th17 cells were detected by immunohistochemistry in infected valves from patients with IE. The expression of IL-21, IL-23, IL-17, and retinoic acid receptor-related orphan receptor C (Rorc) was upregulated in GTF-activated VIC, which may enhance the proliferation of memory Th17 cells in an IL-6-dependent manner. Many chemokines, including chemokine (C-X-C motif) ligand 1 (CXCL1), were upregulated in GTF-activated VIC, which might recruit neutrophils and CD4+ T cells. Moreover, CXCL1 production in VIC was induced in a dose-dependent manner by IL-17 to enhance neutrophil chemotaxis. CXCL1-expressing VIC and infiltrating neutrophils could be detected in infected valves, and serum concentrations of IL-17, IL-21, and IL-23 were increased in patients with IE compared to healthy donors. Furthermore, elevated serum IL-21 levels have been significantly associated with severe valvular damage, including rupture of chordae tendineae, in IE patients. Our findings suggest that VIC are activated by bacterial modulins to recruit neutrophils and that such activities might be further enhanced by the production of Th17-associated cytokines. Together, these factors can amplify the

    Patients with infective endocarditis (IE) are at high risk for post-operative morbidity and death, which might be associated with drug abuse. The purpose of this study is to evaluate the impact of drug dependence on outcomes in patients who have IE and undergo valvular surgery (VS). The Nationwide/National Inpatient Sample 2001-2012 was queried to select patients with IE who had elective VS using International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis and procedure codes. Among them, patients with drug dependence (PDD) were identified, and their health status and post-operative outcomes were compared with those in patients without drug dependence (control group). Chi-square and Wilcoxon rank sum tests as well as multi-variable regression analysis were used for statistics. A total of 809 (12.9%) PDD of the 6,264 patients who underwent VS were evaluated. They were younger compared with those in the control group (39.0 ± 10.8 y vs. 54.4 ± 14.8 y; p infectious complications (OR = 1.5; 95% CI 1.27-1.78), specifically pneumonia (OR = 1.4; 95% CI 1.14-1.74) and sepsis (OR = 1.4; 95% CI 1.16-1.63), renal complications (OR = 1.5; 95% CI 1.23-1.77), and pulmonary embolism (OR = 1.9; 95% CI 1.44-2.52). Further, PDD had 11% longer hospital length of stay than those in the control groups (p endocarditis who underwent valvular surgery and lengthens their hospital stay.

O diagnóstico é suspeito em casos de endocardite sem resposta ao tratamento comum e é confirmado com sorologia com teste de ELISA maior que 1:160. O tratamento na maioria dos casos é cirúrgico, associado a antibioticoterapia prolongada. Alguns casos são resolvidos com tratamento clínico, que inclui doxiciclina, rifampicina, ciproproxacina, gentamicina e tetraciclina. O objetivo deste estudo foi relatar um caso raro de endocardite por brucelose. RELATO DO CASO: Paciente do sexo masculino, 51 anos, trabalhador rural, admitido com quadro de febre e emagrecimento. O ecocardiograma mostrou espessamento e vegetação de válvula aórtica. Uma hemocultura foi positiva para Staphylococcus epidermidis. O tratamento foi iniciado no dia da internação com penicilina cristalina, associada com garamicina, sem melhora em três semanas. Foi suspeitada endocardite por brucelose, colhida sorologia e iniciado o tratamento. Os antibióticos usados foram rifampicina e ciprofloxacin associado à vancomicina, devido o resultado da primeira hemocultura. A sorologia de aglutinação para brucelose foi positiva com resultado de 1:360. O paciente melhorou e recebeu alta da UTI, hemodinamicamente estável e em uso de ciprofloxacin e gentamicina.

    Full Text Available Leptotrichia species are normal constituents of the oral cavity and the genitourinary tract microbiota that are known to provoke disease in immunocompromised patients and rarely in immunocompetent individuals. Following the description of Leptotrichia goodfellowii sp. nov., two cases of endocarditis by this species have been reported. Here, we report a case of Leptotrichia goodfellowii endocarditis in an immunocompetent patient with a valvular allograft. The isolation and identification of Leptotrichia can be challenging, and it is likely that infection with this pathogen is significantly underdiagnosed. A definitive identification, as in this case, most often requires 16S rRNA gene sequencing, highlighting the increasingly important role of this diagnostic modality among immunocompetent patients with undetermined anaerobic bacteremia.

The echocardiogram showed a severe mitral regurgitation and left cavitie's dilatation; transesophageal echocardiogram showed a vegetation in the anterior leaflet of the mitral valve. In blood cultures grew a Gram-negative bacteria identified as Bartonella spp. A PCR demonstrated that it was a Bartonella quintana. The patient was treated with gentamicin, doxiciclin and ceftriaxone with satisfactory evolution. The remaining mitral insufficiency awaits surgical treatment.

    Full Text Available Enterococci are normal inhabitants of gastrointestinal tract, being responsible for 5 to 18% of infective endocarditis and the incidence appears to be increasing. Eleven patients with enterococcal endocarditis were studied. In a case series group, 10 men (average 57 years and one woman (37 years were studied. Two patients had rheumatic heart disease, 5 patients arteriosclerotic disease and one patient chronic renal failure on hemodialysis. Ten patients were treated with ampicillin and gentamycin. Valve replacement was performed in 3 patients with aortic valve endocarditis, one on 8th day and two at the end of the treatment. Overall clinical cure was achieved in 9 patients. Two relapses occurred and 2 patients died as a result of refractory congestive heart failure and cerebral emboli. All of the enterococcal endocarditis cases were community acquired. In conclusion, infective endocarditis in patients with preexistent valvular heart disease, community acquisition and non specific symptoms with bacteriuria should be considered as enterococcal endocarditis.

    Full Text Available Endocarditis is one of the most prevalent forms of cardiac involvement in patients with lupus, as it is considered as one a life-threatening complication. Libman-Sacks endocarditis is common. Infective endocarditis can also cause complications within immunocompromised patients. The aim of this study is to determine particularities of endocarditis in patients with lupus and to look for distinguishing features between infectious or immunological origin. A retrospective study was conducted on patients with lupus presenting endocarditis. Lupus was diagnosed according to the American college of rheumatology criteria. The diagnosis of endocarditis was made based on the modified Duke criteria. The present case report studies seven cases of endocarditis. Six of these patients are women and the other one is a man. They are aged meanly of 29.4 years (extremes: 20-36. Fever was present in all the cases with a new cardiac murmur in six cases and a modification of its intensity in one case. Biologic inflammatory syndrome was present in six cases. Cardiac ultrasound performed in six cases made the diagnosis of endocarditis which involved the left heart valves in five cases and the right heart valves in one case. Valvular insufficiency was identified in six patients. The valve involvement was mitral in two cases, mitro-aortic in two others, aortic in the fifth one and tricuspid in the sixth one. Endocarditis was infectious in 4 cases, thanks to positive blood culture. The germs identified were gram negative bacilli in two cases, anaerobic organism in one case and gram positive cocci in one case. Candida albicans was isolated in one case. Libman-Sacks endocarditis was objectified in three cases. A combination of Libman-Sacks endocarditis with infectious endocarditis was diagnosed in one case. The treatment consisted of antibiotics in four cases with surgery in two cases. The outcome was favorable in five cases and fatal in the two others. Endocarditis in lupus

    Full Text Available Cerebral ischemic processes associated with infective endocarditis caused by Streptococcus bovis are rare; only 2 cases having been reported. Here we report a case of a 50-year-old man with S. bovis endocarditis who presented signs of frontal, parietal and occipital lobe cerebral ischemia. This is the first case reported in which the presence of hemianopsia preceded the endocarditis diagnosis. Initially, the clinical manifestations suggested a systemic vasculitis. Later, vegetating lesions were identified in the aortic valve and S. bovis grew in blood cultures. Antibiotic use and aortic valve replacement eliminated the infection and ceased thromboembolic events. A videocolonoscopy examination revealed no mucosal lesions as a portal of entry in this case, although such lesions have been encountered in up to 70% of reported cases of S. bovis endocarditis.A associação de isquemia cerebral e endocardite por Streptococcus bovis é um evento raro, tendo sido publicados apenas 2 casos anteriormente. Nós relatamos o caso de um homem de 50 anos com endocardite por S. bovis que apresentou sinais isquêmicos nos lobos frontal, parietal e occipital. Este é o primeiro caso em que a hemianopsia precedeu o diagnóstico de endocardite. Inicialmente, o quadro foi confundido com vasculite. Posteriormente, foi confirmada a presença de vegetações na válvula aórtica e a hemocultura identificou S. bovis. Os eventos tromboembólicos foram controlados com o uso de antibióticos e a troca da válvula aórtica. Estudo videocolonoscópico não identificou nenhuma lesão, apesar de lesões colônicas serem descritas em até 70% dos casos de indivíduos com endocardite por S. bovis.

    Full Text Available OBJETIVO: Descrever o caso de uma criança com endocardite infecciosa causada por Haemophilus aphrophilus. DESCRIÇÃO: Menino com febre e calafrios há 20 dias. À internação, apresentava-se febril, descorado e sem sinais de instabilidade hemodinâmica; à ausculta cardíaca, tinha sopro holosistólico em foco mitral. Os exames laboratoriais identificaram anemia (hemoglobina = 9,14 g/dL, leucócitos totais de 11.920 mm³, plaquetas de 250.000 mm³, velocidade de sedimentação das hemácias e proteína C reativa elevadas. O ecocardiograma revelou imagem em válvula mitral, sugestiva de vegetação. Com a hipótese de endocardite, foi iniciada antibioticoterapia com penicilina cristalina (200.000 UI/kg/dia associada à gentamicina (4 mg/kg/dia. No terceiro dia de tratamento, foi identificado Haemophilus aphrophilus em hemoculturas, sendo então trocado o esquema antibiótico para ceftriaxona (100 mg/kg/dia. No 20º dia de internação, encontrava-se pálido, mas sem febre e sem outras queixas. Os exames mostravam hemoglobina = 7,0 g/dL, leucócitos = 2.190 mm³, plaquetas = 98.000 mm³, razão normatizada internacional = 1,95 e R = 1,89. Foi feita hipótese de reação adversa ao ceftriaxona, que foi substituído por ciprofloxacina, 20 mg/kg/dia, até completar 6 semanas de tratamento. Após 72 horas da troca, houve normalização dos exames. Durante seguimento ambulatorial, apresentou insuficiência mitral grave, sendo submetido a troca de válvula por prótese metálica 9 meses após quadro agudo. Há 3 anos encontra-se bem, em acompanhamento ambulatorial.

    Infectious endocarditis results from bacterial or fungal infection of the endocardial surface of the heart and is associated with significant morbidity and mortality. Risk factors include the presence of a prosthetic heart valve, structural or congenital heart disease, intravenous drug use, and a recent history of invasive procedures. Endocarditis should be suspected in patients with unexplained fevers, night sweats, or signs of systemic illness. Diagnosis is made using the Duke criteria, which include clinical, laboratory, and echocardiographic findings. Antibiotic treatment of infectious endocarditis depends on whether the involved valve is native or prosthetic, as well as the causative microorganism and its antibiotic susceptibilities. Common blood culture isolates include Staphylococcus aureus, viridans Streptococcus, enterococci, and coagulase-negative staphylococci. Valvular structural and functional integrity may be adversely affected in infectious endocarditis, and surgical consultation is warranted in patients with aggressive or persistent infections, emboli, and valvular compromise or rupture. After completion of antibiotic therapy, patients should be educated about the importance of daily dental hygiene, regular visits to the dentist, and the need for antibiotic prophylaxis before certain procedures.

    Between 1981 and 1987, 29 patients (20 men and 9 women, mean age 46 +/- 15) underwent a valvular replacement for endocarditis (19 aortic and 10 mitral). There were 25 native and 4 prosthetic valves. In 85% of cases, underlying valvular lesions were present. The oropharyngeal and the respiratory tracts were the most common sources of infection. In 81%, the infecting microorganism was gram-positive. In 21% of cases, a gram-negative was detected, always mixed with a gram-positive. One infection was caused by a Candida. Indications for surgery were severe valvular insufficiency or cardiac failure (90%), refractory sepsis (21%), thromboembolic events (11%). In 22%, multiple factors were present. A biologic valve was chosen in 12 cases (40%). Simultaneously with the valvular replacement, 4 ventricular septal perforations were occluded and 3 valvular annulus abscesses debrided. The operative mortality was 10% (3/29). The one-year survival is 96%. Two patients required reoperation at 6 months and 2 years, for partial dehiscence, with good subsequent evolution. The authors concluded that surgical operation is the most suitable treatment for unstable or complicated endocarditis, in case of cardiac failure, iterative thromboembolic events or refractory sepsis.

    Infective endocarditis is a serious disease of the endocardium of the heart and cardiac valves, caused by a variety of infectious agents, ranging from streptococci to rickettsia. The proportion of cases associated with rheumatic valvulopathy and dental surgery has decreased in recent years, while endocarditis associated with intravenous drug abuse, prosthetic valves, degenerative valve disease, implanted cardiac devices, and iatrogenic or nosocomial infections has emerged. Endocarditis causes constitutional, cardiac and multiorgan symptoms and signs. The central nervous system can be affected in the form of meningitis, cerebritis, encephalopathy, seizures, brain abscess, ischemic embolic stroke, mycotic aneurysm, and subarachnoid or intracerebral hemorrhage. Stroke in endocarditis is an ominous prognostic sign. Treatment of endocarditis includes prolonged appropriate antimicrobial therapy and in selected cases, cardiac surgery. In ischemic stroke associated with infective endocarditis there is no indication to start antithrombotic drugs. In previously anticoagulated patients with an ischemic stroke, oral anticoagulants should be replaced by unfractionated heparin, while in intracranial hemorrhage, all anticoagulation should be interrupted. The majority of unruptured mycotic aneurysms can be treated by antibiotics, but for ruptured aneurysms, endovascular or neurosurgical therapy is indicated. Copyright © 2014 Elsevier B.V.

    A total of 458 cases (11.5%) with valvular heart diseases in the aged (greater than or equal to 60 years) were found among 4,000 consecutive autopsies. They included 204 cases (45%) of aortic regurgitation (AR), 171 cases (37%) of mitral regurgitation (MR), followed by 45 (10%) of aortic stenosis (AS) and 27 cases (6%) of mitral stenosis (MS). As an etiology of the valvular diseases, degenerative type was found in 195 cases (43%), ischemic origin in 91 cases (20%), followed by inflammatory origin such as syphilitic in 51 and infective endocarditis in three, aortitis in two and rheumatic in 49 (11%). Congenital origin was also found in 18 cases (4%). Among various types of valvular diseases in the aged, degenerative AR was most frequently found in 140 cases, followed by MR due to papillary muscle dysfunction in 91 cases. The clinical characteristics in cases with valvular diseases were as follows: atrial fibrillation was prominent in MS; congestive heart failure was found in 60% of cases except those with degenerative AR; cardiac death was frequent in syphilitic and rheumatic AR; association of hypertension was found in 50% of cases with MR and degenerative AR. In this article the characteristics of the valvular heart disease in the aged and additionally its diagnosis and treatment were discussed.

    2009-07-01

    Full Text Available Abstract Introduction Bartonella spp. infection is not rare and must be considered with great care in patients with suspected infective endocarditis, particularly if regular blood cultures remain sterile. Management of these infections requires knowledge of the identification and treatment of these bacteria. Case presentation A 50-year-old Senegalese man was admitted to our Department of Cardiac Surgery with a culture-negative endocarditis. Despite valvular surgery and adequate antibiotic treatment, recurrence of the endocarditis was observed on the prosthetic mitral valve. Heart failure required circulatory support. Weaning off the circulatory support could not be attempted owing to the absence of heart recovery. Bacteriological diagnosis of Bartonella quintana endocarditis was performed by molecular methods retrospectively after the death of the patient. Conclusions This case report underlines the severity and difficulty of the diagnosis of Bartonella quintana endocarditis. The clinical picture suggested possible Bartonella quintana associated myocarditis, a feature that should be considered in new cases.

    Abstract Among culture-negative endocarditis in the United States, Bartonella species are the most common cause, with Bartonella henselae and Bartonella quintana comprising the majority of cases. Kidney manifestations, particularly glomerulonephritis, are common sequelae of infectious endocarditis, with nearly half of all Bartonella patients demonstrating renal involvement. Although a pauci-immune pattern is a frequent finding in infectious endocarditis–associated glomerulonephritis, it is rarely reported in Bartonella endocarditis. Anti–neutrophil cytoplasmic antibody (ANCA) positivity can be seen with many pathogens causing endocarditis and has been previously reported with Bartonella species. In addition, ANCA-associated vasculitis can also present with renal and cardiac involvement, including noninfectious valvular vegetations and pauci-immune glomerulonephritis. Given the overlap in their clinical presentation, it is difficult to differentiate between Bartonella endocarditis and ANCA-associated vasculitis but imperative to do so to guide management decisions. We present a case of ANCA-positive Bartonella endocarditis with associated pauci-immune glomerulonephritis that was successfully treated with medical management alone. PMID:27885316

Se estudiaron, con ecocardiografía y Doppler, a 98 pacientes adictos a la cocaína, por vía endovenosa y/o inhalatoria y se comparó con un grupo de 50 personas no drogadictas. Se definieron las lesiones valvulares como engrosamiento valvular y lesiones del tipo "arrosariado". La edad promedio de los drogadictos fue de 29.1 años (DS 8.31 con un máximo de 66 y mínimo de 14 años; 93 eran de sexo masculino y 45 admitieron adicción endovenosa. Veinte casos tuvieron serología positiva para virus HIV, de los cuales todos excepto uno, reconocieron utilizar la vía endovenosa. El grupo control tuvo una edad promedio de 26.78 años (DS 3.49 y 96% eran de sexo masculino. No hubo diferencias significativas en edad ni sexo entre los dos grupos. El 22.45% de los adictos presentaron lesiones valvulares mientras que no la presentó ninguno del grupo control (p=0.0007. La incidencia de lesiones fue significativamente mayor en la válvula tricúspide (p=0.0004. No se detectó disfunción valvular en ninguno de los casos estudiados, ni se halló diferencia en la presencia de alteraciones valvulares entre los pacientes con y sin reactividad para infección HIV. La prevalencia de afectación valvular en función de la vía de administración de la droga fue significativamente mayor en los pacientes con adicción endovenosa en relación con la vía inhalatoria, 40% versus 7.5% (p= 0.0001. En el presente estudio hemos observado que un porcentaje de adictos a la cocaína presentaba alteraciones valvulares, siendo la tricúspide la más comprometida y en ningún caso hemos encontrado insuficiencia

    Full Text Available Infective endocarditis has different presentations depending on the involvement of valvular and perivalvular structures, and it is associated with high morbidity and mortality. Aortocavitary fistula is a rare complication. We introduce the case of a 48-year-old female with native valve endocarditis, complicated by aortocavitary fistula to the right atrium, and consequently presented with syncope.

    Full Text Available Endocarditis associated with dialysis catheter is a disease that must be suspected in every patient with hemodialysis who develops fever. Multiple valve disease is a severe complication of endocarditis that needs to be managed in a different way. There is very limited data for treatment and every case must be considered individually. We present a patient with this complication and describe the medical treatment and surgical management. We report the case of a 15-year-old patient with acute renal failure that develops trivalvular endocarditis after the hemodialysis catheter was placed, with multiple positive blood culture for Staphylococcus aureus. Transesophageal echocardiography was done and aortic and tricuspid valvular vegetations and mitral insufficiency were reported. Patient was successfully treated by surgery on the three valves, including aortic valve replacement. There is limited data about the appropriate treatment for multiple valvular endocarditis; it is important to consider this complication in the setting of hemodialysis patients that develop endocarditis and, despite the appropriate treatment, have a torpid evolution. In countries where endovenous drug abuse is uncommon, right sided endocarditis is commonly associated with vascular catheters. Aggressive surgical management should be the treatment of choice in these kinds of patients.

    Full Text Available Objective. Endocarditis can have profound and devastating neurological consequences, with the vast majority of these complications in patients with left-sided valvular disease. The approach to the acute management of stroke in children with infective endocarditis is limited by the inadequacy of published data on their clinical course and outcome. Case report. This case report presents a 12 year old girl with diagnosed endocarditis, complicated with intracranial hemorrhage, due to the rupture of an aneurysm of the peripheral branch medial cerebral artery and gradient therapeutic approach, with an excellent final result. Conclusion. Congestive heart failure resulting from valvular insufficiency required mitral valve replacement, after cerebral aneurysm clipping.

    Full Text Available BACKGROUND: Many studies in the literature have warned of the need for investigation of colonic lesions among patients, especially elderly ones, who have bacteremia and/or endocarditis from Streptococcus bovis. Bacteremia and infectious endocarditis from Streptococcus bovis may be related to the presence of neoplastic lesions in the large intestine and hepatic disease. AIM: This report describes a patient who presented infectious endocarditis from Streptococcus bovis associated with colonic carcinoma and tubular-villous adenomas. CONCLUSIONS: The finding of this bacterium among patients with septicemia and/or endocarditis is also related to the presence of villous or tubular-villous adenomas in the large intestine. For this reason, complete and detailed investigation of the large intestine must be performed in patients with infectious endocarditis, even in the absence of intestinal symptoms. An increased incidence of this condition or hepatic dysfunction has been reported among patients with infectious endocarditis from Streptococcus bovis. Patients with infectious endocarditis from Streptococcus bovis and normal colonoscopy may be included in the group at risk for developing colonic cancer. The knowledge that there is an association between endocarditis from Streptococcus bovis and carcinoma of the colon has important clinical implications. If the lesion can be discovered at an early stage, curative resection may become possible.RACIONAL: Diferentes estudos na literatura têm alertado para a necessidade de investigação de lesões cólicas entre doentes, especialmente nos mais idosos, que apresentem bacteremia e/ou endocardite por Streptococcus bovis.

    Full Text Available Valvular heart disease is still a common causes of mortality and morbidity in India and rheumatic heart disease is still far more frequent. AIMS AND OBJECTIVES: To study the prevalence and clinical profile of rheumatic and non - rheumatic valvular heart dise ase in patients attending to Government General Hospital, Kakinada. MATERIALS AND METHODS: 100 Adult patients with valvular abnormalities attending to the Medicine and Cardiology Units of Government General Hospital, Kakinada from Nov 2011 - May 2013 were studied. C linical history including various symptoms, past history of rheumatic fever, followed by systemic examination was done. A detailed cardiovascular examination with relevant investigations and evaluation was done. OBSERVATIONS AND RESULTS: The most common cause of acquired valvular heart disease is Rheumatic Heart Disease. Mitral valve involvement is the most common valve involvement with Mitral regurgitation as the most common valvular lesion. Mitral stenosis is the most common valvular lesion amon g rheumatic valvular heart disease. The most common complaint is breathlessness and the most common complication is Congestive heart failure. Multi valvular lesion is the most common valve involvement in patients presenting with congestive heart failure an d infective endocarditis. Patients having atrial fibrillation are noted to have mitral stenosis more commonly. Mitral stenosis is the valve abnormality commonly noted in patients presenting with haemoptysis, respiratory tract infection and chorea. Left sid ed hemiplegia is common in patients with acquired valvular heart disease. CONCLUSIONS: Though the incidencen of rheumatic valvular disease is decreased in modern era, still continuing in our country. The analysis of the present study gives us insight into the various types of presentation of acquired valvular heart disease and to increase awareness besides early detection of valvular diseases clinically. It also helps in planning of

    Full Text Available The infective endocarditis is an uncommon disease in the Emergency Department. Anyway, the emergency physician may be in front of the complications of this disease. A case of a patient with fever, laboratory signs of infection and an acute heart failure is described in this article. The final diagnosis was infective endocarditis with vegetations on the aortic valve and severe valvular regurgitation. The definition of infective endocarditis according to the major and minor criteria for the diagnosis is discussed. The echocardiography is central in the diagnosis and management of patients with infective endocarditis in the emergency setting, even if the clinical suspicion is very important. The main available therapeutic options in according to the Internation Guidelines are evaluated. The possible complications are also discussed. Several clinical and echocardiographic features identify patients at high risk for a complicated course or with a need for surgery.

    Full Text Available Inflammation of the inner layer of the heart, especially the valvular endothelium, chordae tendinae and mural endocardium was first recognized almost 350 years ago. Over the years it has had many names, but is now generally designated infective endocarditis (IE and has an associated infectious agent. A sterile vegetative process can also affect the valves and is usually referred to as Libman-Sacks endocarditis. The developments of medical science that allowed for our understanding of this entity included refinement of the autopsy, medical microscopy, microbiology, and in recent years, molecular studies. Some observations were misleading but clarification particularly followed the reports of Morgagni, Osler and Libman. As understanding of the pathobiology of infective endocarditis grew so did the effectiveness of therapy. This paper provides a detailed history of the development of the concept of Infective endocarditis citing many key morphological observations and concludes with brief comments about current concepts of pathogenesis as well as a few remarks about therapy.

    Libman-Sacks endocarditis is a well-known and rather common cardiac manifestation of systemic lupus erythematosus. Transesophageal and transthoracic echocardiography are the definitive imaging methods used to evaluate cardiac valvular involvement in this disease. Valvular masses (vegetations) and valvular thickening are 2 common morphologic echocardiographic patterns. Libman-Sacks lesions are typically characterized by single-valve involvement and their small size of 1 to 4 mm.Herein, we present the unusual case of a 22-year-old woman with newly diagnosed systemic lupus erythematosus who had large, sterile vegetations of Libman-Sacks endocarditis that involved the mitral and aortic valves. This compromised coronary blood flow and resulted in ventricular fibrillation cardiac arrest. The vegetations were surgically excised, and the patient's cardiac function recovered. We discuss the treatment of the patient and that of Libman-Sacks endocarditis.

    Patients who have valvular heart disease coming for surgery present many challenges to the anesthesiologist. Over the past 3 decades there has been a persistent improvement in our understanding of the pathophysiology of valvular heart disease and in the surgical techniques for correcting it. With the development of efficient and safe noninvasive monitoring of cardiac function, new surgical techniques, better designs of prosthetic valves, and the development of useful guidelines for choosing the proper timing of surgical intervention, patients who have valvular disease with varying physiology can be encountered in the perioperative period. The perioperative physician has to be aware of the varying effects of hemodynamic variables on this subpopulation of patients.

    A patient with staphylococcal endocarditis of unknown valvular location and resistant to antibiotic therapy was studied in order to localize the site of infection prior to cardiac surger. The injection of contrast material into the right atrium visualized tricuspid vegetations which were confirmed at surgery. In such situations, forward angiographic studies constitute a safe, simple, and potentially diagnostic procedure which avoids the hazards of advancing a catheter across an infected valve.

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

    Antineutrophil cytoplasmic antibodies (ANCA) associated with infective endocarditis are a rare disorder. The condition can mimic primary systemic vasculitis (i.e. granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis). Thus, a wrong diagnosis of valvular involvement related to primary systemic vasculitis can be made in patients exhibiting ANCA associated with infective endocarditis. Because treatment of both conditions is different, this wrong diagnosis will lead to dramatic consequences in these latter patients. This review reports the state of knowledge and proposes an algorithm to follow when confronted to a possible case of ANCA associated with infective endocarditis.

Sin embargo, conlleva de por vida un elevado riesgo acumulado de complicaciones relacionadas con las prótesis (tromboembolismos, endocarditis, deterioro estructural de las prótesis biológicas, reintervenciones y con la necesidad de anticoagulación. Por eso, la reparación valvular emerge con fuerza como alternativa en el manejo de la insuficiencia aórtica, particularmente en los individuos más jóvenes. Se realiza hoy con una mortalidad quirúrgica baja y los grupos quirúrgicos con gran experiencia reportan buenos resultados en términos de durabilidad. Además, el desarrollo y la difusión de las técnicas de cirugía conservadora de la válvula aórtica para el tratamiento del aneurisma de aorta ascendente han mejorado nuestra comprensión del papel destacado de la raíz de aorta en la función valvular y han conducido al desarrollo de soluciones quirúrgicas adaptadas a cada caso de insuficiencia aórtica, con o sin enfermedad de la raíz.

    2002-01-01

    Infective endocarditis especially where blood culture is negative frequently causes problems in diagnosis despite of many nonspecific inflammation parameters. Procalcitonin (PCT) concentration is a new marker of severe bacterial and fungal infection. The aim of this study was to evaluate the usefulness of PCT concentration assessment in the diagnosis of uncomplicated infective endocarditis of bacterial etiology. The study group consisted of 30 patients with ongoing infective endocarditis in the course of acquired valvular heart disease. The diagnosis of bacterial endocarditis was established according to the Duke criteria on the basis of: clinical examination, laboratory investigations (inflammatory parameters, transthoracic and transesophageal echocardiography) and positive blood cultures. Patients with sepsis, concomitant infections and in an early postoperative period were excluded. Two control groups consisted of: 10 patients without endocarditis and other infections and another 10 patients without endocarditis and with an urinary tract infection. Serum procalcitonin concentrations were measured by an immunoluminometric assay (LUMItest PCT set). Mean serum PCT concentrations in patients with endocarditis (0.12 +/- 0.13, range 0-0.4 ng/ml) were significantly higher than in control group without infection (0.03 +/- 0.05, range 0-0.1 ng/ml) and higher than in control group with an urinary tract infection (0.02 +/- 0.04, range 0-0.1 ng/ml). However in 12 patients (of 30) were below sensitivity of the method and in the rest were within normal range (< 0.5 ng/ml). Serum PCT concentration assessment seems to have no value in the diagnosis of uncomplicated infective endocarditis.

    Coxiella burnetii endocarditis is considered to be a late complication of Q fever in patients with preexisting valvular heart disease (VHD). We observed a large transient aortic vegetation in a patient with acute Q fever and high levels of IgG anticardiolipin antibodies (IgG aCL). Therefore, we sought to determine how commonly acute Q fever could cause valvular vegetations associated with antiphospholipid antibody syndrome, which would be a new clinical entity. We performed a consecutive case series between January 2007 and April 2014 at the French National Referral Center for Q fever. Age, sex, history of VHD, immunosuppression, and IgG aCL assessed by enzyme-linked immunosorbent assay were tested as potential predictors. Of the 759 patients with acute Q fever and available echocardiographic results, 9 (1.2%) were considered to have acute Q fever endocarditis, none of whom had a previously known VHD. After multiple adjustment, very high IgG aCL levels (>100 immunoglobulin G-type phospholipid units; relative risk [RR], 24.9 [95% confidence interval {CI}, 4.5-140.2]; P = .002) and immunosuppression (RR, 10.1 [95% CI, 3.0-32.4]; P = .002) were independently associated with acute Q fever endocarditis. Antiphospholipid antibody syndrome with valvular vegetations in acute Q fever is a new clinical entity. This would suggest the value of systematically testing for C. burnetii in antiphospholipid-associated cardiac valve disease, and performing early echocardiography and antiphospholipid dosages in patients with acute Q fever. © The Author 2015.

    2009-02-20

    Valvular heart diseases remain frequent in Western countries since the decrease in the frequency of rheumatic heart diseases has been replaced by degenerative valve diseases. Thus, there is an important increase in the prevalence of valvular heart diseases after the age of 65. The frequency of heart valve disease in the elderly has an important impact on patient management, given the frequency of comorbidity and the increase in the risk of interventions. The two other most frequent causes of heart valve disease are rheumatic fever and infective endocarditis. In Europe, the two most frequent heart valve diseases are calcified aortic stenosis and mitral regurgitation, while aortic regurgitation and mitral stenosis are rare. Rheumatic heart diseases remain frequent in developing countries. Their prevalence is underestimated by clinical screening alone. Systematic echocardiographic screening estimates the prevalence of rheumatic heart valve disease to be between 20 and 30 per 1000 in children of school age.

    Full Text Available In middle income countries, the burden of rheumatic heart disease (RHD remains high, but the prevalence of other heart valve diseases may rise as the population life expectancy increases. Here, we compared population-based data on surgical procedures to assess the relative importance of causes of heart valve disease in Salvador, Brazil.Medical charts of patients who underwent surgery for valvular heart disease from January 2002-December 2005 were reviewed. Incidence of surgery for valvular heart disease was calculated. Logistic regression was used to identify factors associated with in-hospital death following surgery. The most common etiologies for valvular dysfunction in 491 valvular heart surgery patients were RHD (60.3%, degenerative valve disease (15.3%, and endocarditis (4.5%. Mean annual incidence for surgeries due to any valvular heart diseases, RHD, and degenerative valvular disease were 5.02, 3.03, and 0.77 per 100,000 population, respectively. Incidence of surgery due to RHD was highest in young adults; procedures were predominantly paid by the public health sector. In contrast, the incidence of surgery due to degenerative valvular disease was highest among those older than 60 years of age; procedures were mostly paid by the private sector. The overall in-hospital case-fatality ratio was 11.9%. Independent factors associated with death included increase in age (odds ratio: 1.04 per year of age; 95% confidence interval: 1.02-1.06, endocarditis (6.35; 1.92-21.04, multiple valve operative procedures (4.35; 2.12-8.95, and prior heart valve surgery (2.49; 1.05-5.87.RHD remains the main cause for valvular heart surgery in Salvador, which primarily affects young adults without private health insurance.

The most common etiologies for valvular dysfunction in 491 valvular heart surgery patients were RHD (60.3%), degenerative valve disease (15.3%), and endocarditis (4.5%). Mean annual incidence for surgeries due to any valvular heart diseases, RHD, and degenerative valvular disease were 5.02, 3.03, and 0.77 per 100,000 population, respectively. Incidence of surgery due to RHD was highest in young adults; procedures were predominantly paid by the public health sector. In contrast, the incidence of surgery due to degenerative valvular disease was highest among those older than 60 years of age; procedures were mostly paid by the private sector. The overall in-hospital case-fatality ratio was 11.9%. Independent factors associated with death included increase in age (odds ratio: 1.04 per year of age; 95% confidence interval: 1.02–1.06), endocarditis (6.35; 1.92–21.04), multiple valve operative procedures (4.35; 2.12–8.95), and prior heart valve surgery (2.49; 1.05–5.87). Conclusions/Significance RHD remains the main cause for valvular heart surgery in Salvador, which primarily affects young adults without private health insurance. In contrast, surgery due to degenerative valvular disease primarily impacts the elderly with private health insurance. Strategies to reduce the burden of valvular heart disease

    Among culture-negative endocarditis in the United States, Bartonella species are the most common cause, with Bartonella henselae and Bartonella quintana comprising the majority of cases. Kidney manifestations, particularly glomerulonephritis, are common sequelae of infectious endocarditis, with nearly half of all Bartonella patients demonstrating renal involvement. Although a pauci-immune pattern is a frequent finding in infectious endocarditis-associated glomerulonephritis, it is rarely reported in Bartonella endocarditis. Anti-neutrophil cytoplasmic antibody (ANCA) positivity can be seen with many pathogens causing endocarditis and has been previously reported with Bartonella species. In addition, ANCA-associated vasculitis can also present with renal and cardiac involvement, including noninfectious valvular vegetations and pauci-immune glomerulonephritis. Given the overlap in their clinical presentation, it is difficult to differentiate between Bartonella endocarditis and ANCA-associated vasculitis but imperative to do so to guide management decisions. We present a case of ANCA-positive Bartonella endocarditis with associated pauci-immune glomerulonephritis that was successfully treated with medical management alone.

    Endocarditis caused by Staphylococcus warneri and necessitating valve replacement occurred in a previously healthy 32-year-old patient following vasectomy. No sign of an underlying valvular defect was noted during the operation. S. warneri is a recently identified species of coagulase-negative staphylococci. Endocarditis caused by coagulase-negative staphylococci is uncommon in young, healthy patients with normal heart valves and has not previously been described as a complication of vasectomy. Similarly, infections caused by S. warneri have not previously been described in humans.

    The HACEK microorganisms (Haemophilus spp, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae) account for 3% of the cases of endocarditis. They have the following similar clinical and microbiological properties: are Gram-negative bacilli, more easily isolated in aerobic media; their cultures require prolonged incubation time for growing (mean, 3.3 days); and may be considered part of normal flora of upper respiratory tract and oropharynx. The following characteristics have been identified in endocarditis caused by the HACEK microorganisms: insidious clinical findings; difficult diagnosis due to the fastidious nature of the microorganisms; and negative cultures. The Eikenella corrodens endocarditis was first described in 1972. That microorganism continues to be a rare etiological agent. We report the case of a female patient with native valve, who had Eikenella corrodens infective endocarditis.

    P. micra is an anaerobic Gram-positive cocci, and a known commensal organism of the human oral cavity and gastrointestinal tract. Although it has been classically described in association with endodontic disease and peritonsillar infection, recent reports have highlighted the role of P. micra as the primary pathogen in the setting of invasive infections. In its most recent taxonomic classification, P. micra has never been reported causing infectious endocarditis in humans. Here, we describe a 71 year-old man who developed severe native valve endocarditis complicated by aortic valvular destruction and perivalvular abscess, requiring emergent surgical intervention. Molecular sequencing enabled identification of P. micra. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Infectious endocarditis (IE) represents a rare pathology in children, but with lethal potential. The goal of the therapy is fast and total eradication of the infection. To study particularities in diagnosis and treatment for infectious endocarditis in children. Children with infectious endocarditis hospitalized between January 2007 - February 2012 in the Cardiology Department of the ,,Sfânta Maria" Children Emergency Hospital of lasi have been included in the study. The patients are aged between 23 days and 16 years, the average age being 4 years old. At approximately 88% of the patients (14 cases), the endocardial damage appeared in the pre-existent valvular lesions, specially mitral and aortal. As associated congenital malformations, the patients prevailingly presented ventricular septal defect, mitral valve prolapse, arterial canal persistence, aortic stenosis, coarctation of the aorta. Blood cultures were collected and the most frequent identified etiological agents were: Staphylococcus coagulase-positive, Streptococcus mitis, Staphylococcus speciae coagulase-negative, Staphylococcus haemolyticus, Streptococcus bovis, Escherichia coli, for which the antibiogram showed sensitivity for beta-lactam, cephalosporins, glycopeptides, trimethoprim-sulfamethoxazole, rifampicin, quinolone, lincosamides, oxazolidinones, and thus specific treatment was set up according to the antibiogram. The infectious endocarditis is a serious disease that affects young age too, leading towards exitus in some cases. Diagnostic imaging and early blood cultures are of relevance in order to intervene promptly. The treatment must be targeted and applied as fast as possible.

    Valvular heart disease (VHD) is a common clinical entity. Recognition of decompensated VHD is crucial to instituting appropriate workup and management. Initial evaluation focuses on hemodynamics, peripheral perfusion, volume overload, and active myocardial ischemia. Initial therapy is targeted at improving hemodynamics, fluid status, and decreasing myocardial ischemia before intervention. Echocardiography can rapidly identify VHD etiology and severity along with physical examination findings. Owing to improved survival with cardiac surgery over the past several decades, prosthetic valve dysfunction should be recognized and initial treatment understood. Mechanical circulatory support is increasingly part of clinical practice in stabilizing patients with decompensated VHD. Copyright © 2017 Elsevier Inc. All rights reserved.

  7. Infective endocarditis causing mitral valve stenosis - a rare but deadly complication: a case report.

    Hart, Michael A; Shroff, Gautam R

    2017-02-17

    Infective endocarditis rarely causes mitral valve stenosis. When present, it has the potential to cause severe hemodynamic decompensation and death. There are only 15 reported cases in the literature of mitral prosthetic valve bacterial endocarditis causing stenosis by obstruction. This case is even more unusual due to the mechanism by which functional mitral stenosis occurred. We report a case of a 23-year-old white woman with a history of intravenous drug abuse who presented with acute heart failure. Transthoracic echocardiography failed to show valvular vegetation, but high clinical suspicion led to transesophageal imaging that demonstrated infiltrative prosthetic valve endocarditis causing severe mitral stenosis. Despite extensive efforts from a multidisciplinary team, she died as a result of her critical illness. The discussion of this case highlights endocarditis physiology, the notable absence of stenosis in modified Duke criteria, and the utility of transesophageal echocardiography in clinching a diagnosis. It advances our knowledge of how endocarditis manifests, and serves as a valuable lesson for clinicians treating similar patients who present with stenosis but no regurgitation on transthoracic imaging, as a decision to forego a transesophageal echocardiography could cause this serious complication of endocarditis to be missed.

    The pathogenicity of Pasteurella gallinarum for mature leghorn chickens was investigated by inoculating thirty 52-week-old chickens intravenously with live P. gallinarum. Each chicken was inoculated once daily for 5 days at one of three different dosage levels with either the type strain ATCC 13361 or a field isolate from a chicken with endocarditis. Chickens were necropsied after death or euthanasia. Valvular endocarditis was present in seven chickens given the field isolate and five chickens given the type strain. Other lesions detected were myocarditis, hepatic and splenic infarcts, nephritis, pneumonia, and encephalitis. At necropsy, P. gallinarum was reisolated from hearts, livers, spleens, lungs, kidneys, and blood. Controls injected with sterile broth had no lesions of endocarditis, nor was P. gallinarum isolated from them. The results confirm the pathogenicity of P. gallinarum for the heart valves of mature chickens.

    The prevalence of radiation-associated cardiac disease is increasing due to prolonged survival following mediastinal irradiation. Side effects of radiation include pericarditis, accelerated coronary artery disease, myocardial fibrosis and valvular injury. We evaluated the cases of three young patients with evidence of significant valvular disease following mediastinal irradiation. One patient underwent the first reported successful aortic and mitral valve replacement for radiation-associated valvular disease (RAVD) as well as concurrent coronary artery revascularization. A review of the literature revealed 35 reported cases of RAVD, with only one successful case of valve replacement that was limited to the aortic valve. Asymptomatic RAVD is diagnosed 11.5 years after mediastinal irradiation compared with 16.5 years for symptomatic patients, emphasizing that long-term follow-up is important for patients receiving mediastinal irradiation. This study defines a continuum of valvular disease following radiation that begins with mild asymptomatic valvular thickening and progresses to severe valvular fibrosis with hemodynamic compromise requiring surgical intervention. 32 refs.

    Invasive dental procedures are often indicated before cardiac valve surgery. The purpose of this case-control study was to determine the risks and benefits of concomitant dental and thoracic surgery. Critically ill cardiac inpatients requiring cardiac valve surgery were referred by the Department of Thoracic and Cardiovascular Surgery to our Oral Medicine consult service. Those requiring dental extractions were considered for dental treatment during the same general anesthetic as the cardiac surgery. These study patients were compared with control patients who had extractions before valve surgery in a different setting. There was no attempt to analyze the impact of this practice on the development of infective endocarditis. All patients received broad-spectrum antibiotics during dental surgery. Twenty-one patients had concomitant oral and cardiac valve surgery. Seventeen patients were in the control group. There were no statistically significant differences between cases and controls in demographics, length of stay, nature of the dental surgery, mean number of teeth removed, oral bleeding, or postoperative infections. One patient in the control group developed prosthetic valve endocarditis versus none in the concomitant surgery group. This case-control study suggests that concomitant surgical procedures for dental and valvular heart disease can be accomplished without clinically significant oral complications. Given the risk from poor oral health following cardiac valve surgery, this approach should be considered for patients who would benefit by avoiding a second general anesthetic and/or a delay in cardiac surgery, and by having their oral surgery performed in the safest environment.

    Full Text Available Acute aortic regurgitation (AAR due to infective endocarditis (IE is a serious disease and usually requires surgical treatment. Our study aims to compare the clinical, echocardiographic, and microbiological characteristics as well as in-hospital outcome of patients with AAR according to the severity of heart failure (HF and to evaluate predictors of in-hospital mortality in a tertiary centre. In a prospective analysis, we compared patients with NYHA functional class I-II HF (G1 vs. functional class III-IV HF (G2. From 06/92 to 07/16, 439 patients with IE were hospitalized; 86 presented AAR: (G1, 39: 45.4% y G2, 47: 54.7%. The G1 had higher prosthetic IE (43.6% vs. 17%, p 0.01. All G2 patients had dyspnoea vs. 30.8% of the G1 (p < 0.0001. There were no differences in clinical, echocardiographic and microbiological characteristics. Surgical treatment was indicated mainly due to infection extension or valvular dysfunction in G1 and HF in G2. In-hospital mortality was 15.4% vs. 27.7% (G1 and G2 respectively p NS. In multivariate analysis, health care-associated acquisition (p 0.001, negative blood cultures (p 0.004, and functional class III-IV HF (p 0.039 were in-hospital mortality predictors. One-fifth of the patients with EI had AAR. Half of them had severe HF which needed emergency surgery and the remaining needed surgery for extension of the infection and / or valvular dysfunction. Both groups remain to have high surgical and in-hospital mortality. Health care-associated acquisition, negative blood cultures and advanced HF were predictors of in-hospital mortality

    In the last 30 years, major improvements have been made in understanding the pathogenesis, diagnosis and treatment of infective endocarditis. Nevertheless, mortality still remains high, close to 30-40% at 1 year, and its reduction remains the main challenge. Moreover, important epidemiological changes have been recorded. Social changes in Western countries have led to an increase in the mean length of life, and thus in degenerative valvular diseases, whereas rheumatic heart disease has almost disappeared. Increasing medicalization has led to a rise in complications and diseases related to longer hospital stay, surgical therapies and other invasive interventions. At the same time, there is an increase in immunosuppressive therapies, diseases such as cancer, diabetes mellitus and renal insufficiency that may enhance the disease. Further knowledge is needed for specific subgroups to improve both treatment and prognosis. Nevertheless, randomized trials are lacking to guide the management of the disease, and the role and indications of antibiotic prophylaxis are still the subject of debate. International multicenter studies are providing new important findings based on the experience of tertiary centers; these results may reflect referral biases. The proposal of an Italian national registry on infective endocarditis (RIEI) will overcome these limitations and provide a wide picture of the national presentation of the disease. The aim of the registry is to improve the management of infective endocarditis, through a better understanding of demographic, clinical, therapeutic and prognostic features of the disease in the real world. The background, rationale, aims and expected results of the registry are reviewed.

    This study aims to define risk factors as well as their association with microbiology and clinical outcomes in a large US infective endocarditis population. Hospital records were searched for appropriate infective endocarditis-related ICD codes from 16 July 2007 to 13 August 2015. A total of 363 cases were retrospectively identified that met definite Modified Duke Criteria for infective endocarditis and were analyzed by age group, causative organism, and associated risk factors for use of valvular surgical intervention, 30/90/180-day mortality after admission, and embolic phenomena. Chronic hemodialysis was the most common risk factor (26.7% of cases). Of all age groups, those aged 78+ years had the lowest 30-day mortality but those aged 58-77 years had the highest mortality (p = 0.039). Staphylococcus aureus was the most prevalent causative organism. Those aged 78-97 years were more likely to have enterococcal infective endocarditis than those aged 18-27 years (p = 0.0144). Chronic hemodialysis associated infective endocarditis was more likely to be caused by coagulase-negative staphylococcus (p = 0.0121) and have a higher 30-day mortality (p = 0.141) than intravenous drug use associated infective endocarditis. Intravenous drug use and chronic hemodialysis were similarly likely to be caused by S. aureus. Intravenous drug use associated infective endocarditis was more likely to be caused by viridans group streptococci (p = 0.0001). Fungal infective endocarditis was most likely to embolize. Chronic hemodialysis patients were less likely to undergo valvular surgery (p = 0.001) and those with chronic hemodialysis who did had lower mortality than those only managed medically that did not reach statistical significance (p = 0.2991). Infective endocarditis caused by coagulase-negative staphylococci had the greatest 30-day mortality at 31.3% but did not reach statistical significance over all other causative organisms (p = 0

Se caracteriza por regurgitación de la sangre hacia las aurículas, con disminución del gasto cardiaco, lo que lleva a sobrecarga de volumen con hipertrofia excéntrica e insuficiencia cardiaca congestiva. Este reporte tiene como objetivo describir los hallazgos clínicos y de necropsia de un canino, sugestivos de una endocardiosis valvular. El paciente ingresó por consulta externa a la Clínica Veterinaria Carlos Martínez Hoyos, de la Universidad de Nariño (Pasto, Colombia. Su propietario lo reportó enfermo desde hacía dos meses, con signos de enfermedad respiratoria, pérdida de peso y decaimiento. En el examen clínico se encontraron membranas mucosas muy pálidas, disnea inspiratoria, estertores, desdoblamiento de S2, soplo de regurgitación mesosistólico grado 4 y dilatación abdominal con signo de choque de onda positivo. En la necropsia se evidenció abundante cantidad de material de aspecto acuoso traslúcido en cavidad abdominal, torácica y pericárdica, corazón severamente aumentado de tamaño, redondeado, con engrosamiento de válvulas atrioventriculares, hígado con moderada disminución de tamaño y evidencia de lobulillación, riñones severamente disminuidos de tamaño y pálidos de superficie irregular con presencia de múltiples áreas quísticas en región corticomedular. Se tomaron muestras de estos tejidos y se fijaron en formol bufferado al 10 %, para después ser procesadas para análisis histopatólogico en el Laboratorio de Patología de la Universidad de Nariño, mediante la técnica de hematoxilina y eosina de rutina. De esta manera se diagnostica como enfermedad valvular degenerativa.

Up to 9% of autopsies of cancer patients show non infectious valvular masses. However, bivalvular involvement is not frequently occurring in 9% of non bacterial thrombotic endocarditis. We report a patient with ovarian cancer who presented aphasia. The MRI was compatible with cerebral ischemia. The transthoracic echocardiogram was normal and a transesophageal echocardiogram showed vegetations in aortic and mitral valves. We emphasize the importance of suspecting non bacterial thrombotic endocarditis in patients with cancer and systemic embolism and the low frequency of bivalvular involvement.

    This report suggests a strong association between coagulase-negative Staphylococcus simulans and endocarditis in broiler chickens of a single flock. Clinical signs included increased mortality and lameness, and some dead chickens were found on their backs. Lesions included cauliflower-like, fibrinous vegetative lesions on the left atrioventricular valve; cream-coloured, necrotic foci of varying size in the liver; and necrosis of the femoral head. Histopathological examination of the heart revealed multifocal conglomerates of bacterial colonies attached to the valvular endocardium, threads of fibrin, and inflammatory cells with the presence of heterophils. S. simulans strains were first identified by API ID32, and then confirmed with Matrix-Assisted Laser Desorption Ionization Time-of-Flight Mass Spectrometry and by partial sequencing of the rpoB and dnaJ genes. These bacteria were resistant to methicillin but sensitive to vancomycin and characterized by slime production and protease activity.

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

    Unlike the Western world, valvular disease ranks among the major cardiovascular afflictions in Africa. Acute rheumatic fever and chronic rheumatic valvular disease in their most virulent form are still commonly encountered and impose a huge burden on limited healthcare resources. We performed a systematic review of the literature with PubMed using rheumatic fever, rheumatic heart disease, valvular disease, warfarin anticoagulation, and pregnancy as search items. Literature emanating from Africa was emphasized. Epidemiology, current concepts on pathogenesis, and aspects of the medical and surgical management of this disease as seen from an African perspective are presented. The association of pregnancy with mitral stenosis is common and may be fatal if not managed appropriately. A practical approach to these patients is presented to optimize maternal and fetal outcome. Pregnant patients with mechanical valves require careful attention to ensure maternal survival and prevent fetal warfarin embryopathy. Prolonged subcutaneous heparin and frequent monitoring of the partial thromboplastin time are impractical in this setting, and the merits of different anticoagulation regimens are discussed. Congenital submitral aneurysms are a unique cause of mitral regurgitation, with the vast majority of cases originating from sub-Saharan Africa. Although the precise etiology is as yet unclear, the clinical and echocardiographic features are sufficiently characteristic to allow a preoperative diagnosis to be made. Transesophageal echocardiography allows much better definition of the size and anatomic relationships of the aneurysm. Surgical resection can be difficult but is usually curative. Mitral valve prolapse and endocarditis constitute the remaining frequent causes of valvular disease and are discussed briefly. The spectrum and presentation of valvular disease in Africa are uniquely different from elsewhere. Together with socioeconomic issues and the HIV pandemic, this fact

    Full Text Available Descrito inicialmente en 1957 por Robert Austrian, el síndrome que lleva su nombre se define como la tríada de neumonía, endocarditis y meningitis secundarias a una infección invasiva por Streptococcus pneumoniae. Desde entonces, y debido a su infrecuencia, se han reportado muy pocos casos en la literatura científica. A continuación se presenta el caso de un paciente de 61 años de edad con un cuadro inicial de meningitis bacteriana por S. pneumoniae, acompañado de neumonía bacteriana e insuficiencia mitral grave asociada a cuatro vegetaciones sobre la cara auricular de la valva posterior, con ruptura y prolapso de su festón central posterior. Se aisló S. pneumoniae, serotipo 18C, en líquido cefalorraquídeo y en dos hemocultivos. El paciente recibió antibióticos de amplio espectro y fue sometido a reemplazo valvular temprano con un resultado clínico satisfactorio. El principal factor pronóstico de esta condición lo determina el daño valvular subsecuente, sobre todo en pacientes con compromiso de la válvula aórtica, por lo que es necesario identificar tempranamente la extensión del compromiso valvular y definir oportunamente el tratamiento quirúrgico y antibiótico del paciente. En casos menos frecuentes, en los que solo hay compromiso de la válvula mitral, la evolución clínica es menos aguda y, por lo general, el tratamiento antibiótico dirigido y las medidas de soporte avanzado suelen ser suficientes para su control.

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

    Full Text Available Aerococcus viridans is an infrequent human pathogen and few cases of infective endocarditis have been reported. A case involving a 69-year-old man with colon cancer and hemicolectomy 14 years previously, without recurrence, is reported. A diagnosis of native mitral valve endocarditis was established on the basis of clinical presentation, characteristic echocardiographic findings and pathological specimen examination after urgent valve replacement. A viridans endocarditis appears to be particularly virulent, requiring a surgical approach in four of 10 cases reported and death in one of nine. Given the aggressive nature of A viridans endocarditis and the variable time to diagnosis (a few days to seven months, prompt recognition of symptoms and echocardiography, in addition to blood cultures, should be performed when symptoms persist.

    A 41-year-old African male presented with worsening dyspnea and cachexia concerning for congestive heart failure. Transesophageal echocardiogram revealed a large mass attached to the aortic valve leaflet, mass attached to the flail anterior mitral valve leaflet, severe pulmonary hypertension and dilatation of the aortic root along with fistula between the right coronary aortic cusp and the right ventricular (RV) outflow tract. Blood cultures grew Abiotrophia Defectiva (AD) sensitive to vancomycin. Patient underwent emergent surgical closure of aorto RV fistula and aortic root replacement along with pulmonary and mitral valve replacement. Endocarditis caused by AD has been reported to result in heart failure, septic embolization and destruction of the valve despite use of appropriate antibiotics. To our knowledge, this is the only case of AD endocarditis without any identified entrance route; requiring replacement of pulmonary, mitral and aortic valve due to extensive valvular damage and large vegetations.

    Full Text Available Infective endocarditis is defi ned as an infection of the endocardial surface of the heart. Its intracardiac effects include severe valvular insuffi ciency, which may lead to intractable congestive heart failure and myocardialabscesses. This disease still carries a poor prognosis and a high mortality.A severe case of infective endocarditis with its complications is presented. A man with aortic prosthetic valve due to earlier aortic stenosis and corrected aortal coarctation and implanted pacemaker presentedwith prolonged unexplained fever, malaise, sweating, weight loss (15 kg/4 months and lumbar pain. He was treated with broad-spectrum antibiotics prior IE diagnosis was considered. Echocardiogram showedaortic vegetations and possible periaortal abscess formation. Nonspecifi c infl ammation parameters were high positive. Cultures were constantly negative. His condition had deteriorated suddenly, and he had presentedwith worsening of cutaneous vasculitis, subacute glomerulonephritis and subsequent acute respiratory distress syndrome and septic shock. This patient survived with residual bilateral necrosis of the feet andtoxic peroneal paresis. At the end transthoracic echocardiogram showed enlarged heart chambers, LV mild dilated and concentric hypertrophy with ejection fraction about 40%, degenerative postinfl ammatory mitralvalve changes, mild mitral regurgitation and tricuspid regurgitation, postinfl ammatory aortic root fi brosis and moderate aortic valve stenosis (AVPG max 50,9 mmHg, AVPG mean 24 mmHg with no pericardial effusion. Initial suspicion of Q fever was defi nitely excluded by serological testing showing nonspecifi c IgM positivity,probably rheumatoid factor related.

  18. Nuclear Medicine in Diagnosis of Prosthetic Valve Endocarditis: An Update

    Musso, Maria; Petrosillo, Nicola

    2015-01-01

    Over the past decades cardiovascular disease management has been substantially improved by the increasing introduction of medical devices as prosthetic valves. The yearly rate of infective endocarditis (IE) in patient with a prosthetic valve is approximately 3 cases per 1,000 patients. The fatality rate of prosthetic valve endocarditis (PVE) remains stable over the years, in part due to the aging of the population. The diagnostic value of echocardiography in diagnosis is operator-dependent and its sensitivity can decrease in presence of intracardiac devices and valvular prosthesis. The modified Duke criteria are considered the gold standard for diagnosing IE; their sensibility is 80%, but in clinical practice their diagnostic accuracy in PVE is lower, resulting inconclusively in nearly 30% of cases. In the last years, these new imaging modalities have gained an increasing attention because they make it possible to diagnose an IE earlier than the structural alterations occurring. Several studies have been conducted in order to assess the diagnostic accuracy of various nuclear medicine techniques in diagnosis of PVE. We performed a review of the literature to assess the available evidence on the role of nuclear medicine techniques in the diagnosis of PVE. PMID:25695043

A dilated fundoscopic exam, Humphrey visual field test, transthoracic echocardiogram, abdominal computed tomography (CT, and blood cultures were all performed.Results: A dilated fundoscopic exam revealed temporal segmental optic disc pallor on the left, and Humphrey visual field testing demonstrated a dense left cecocentral scotoma. When the patient developed fever (103.9°F and palpitations, transthoracic echocardiogram revealed valvular vegetations, and contrast CT of the abdomen revealed an abscess in the dome of the liver likely due to an infectious thrombus. Blood cultures grew viridians group streptococci in three separate peripheral collections.Conclusion: This case illustrates that a sudden cecocentral scotoma may be the initial manifestation of SBE.

    A 52-yr-old man who had a bioprosthetic aortic valve developed Staphylococcus aureus bacteremia. Despite antibiotic therapy he had persistent pyrexia and developed new conduction system disturbances. Echocardiography did not demonstrate vegetations on the valve or an abscess, but gallium scintigraphy using SPECT clearly identified a focus of intense activity in the region of the aortic valve. The presence of valvular vegetations and a septal abscess was confirmed at autopsy. Gallium scintigraphy, using SPECT, provided a useful noninvasive method for the demonstration of endocarditis and the associated valve ring abscess.

    Full Text Available Since the 1960s, regular hemodialysis (HD was recognized as a risk factor for the development of infective endocarditis (IE, particularly at vascular access sites. The present report describes our experience at the Etat Major General Agadir, Morocco, of taking care of IE in patients on regular dialysis. A retrospective analysis was made of five cases of IE in patients receiving re-gular HD having arteriovenous fistula as vascular access. They were sent from four private centers and admitted in our formation between January 2004 and March 2009. Infective endocarditis was detected after 34.5 months following initiation of dialysis. The causative organisms included Sta-phylococcus and Enterococcus in two cases each and negative blood culture in one case. A recent history of infection (<3 months of the vascular access was found in three cases. Peripheric embolic phenomena were noted in two cases. A pre-existing heart disease was common and contributed to heart failure. Mortality was frequent due to valvular perforations and congestive heart failure, making the medical treatment alone unsatisfactory. Two patients survived and three of our patients received a prosthetic valve replacement, with a median survival after surgery of 10.3 months/person. The clinical diagnosis of infective endocarditis in regularly dialyzed patients remains difficult, with the presence of vascular calcification as a common risk factor. The vascular catheter infections are the cardinal gateway of pathogenic organisms, which are mainly Staphlococcus. The prognosis is bad and the mortality is significant, whereas medical and surgical treatments are often established in these patients who have many factors of comorbidity.

    Full Text Available BACKGROUND Among the cardiovascular diseases acquired, valvular heart disease is one of the common causes of mortality and morbidity in India. An average of 40% of causes is rheumatic valvular heart diseases of all patients admitted with heart diseases. Male preponderance has been noted by most of the physicians in rheumatic heart disease in India. Acquired valvular heart diseases are mitral valve prolapse syndrome, papillary muscle dysfunction, the rupture of chordae tendineae, calcified mitral annulus, calcified aortic stenosis, aortic regurgitation due to syphilis, connective tissue disorders (Marfan’s syndrome, osteogenesis imperfect and systemic lupus erythematosus, atherosclerosis, hypertension and infective endocarditis. Other less common causes are recurrent pulmonary embolism, tuberculosis, cardiac tumours, carcinoid tumours, cardiac surgery for congenital cardiac anomalies and trauma. MATERIALS AND METHODS It is a prospective study on adult patients with valvular abnormalities attending to the Medicine and Cardiology Units of Government General Hospital, Kakinada, between November 2014-May 2017. Total 100 in-patients were included in this study as per inclusion and exclusion criteria. Inclusion Criteria- All patients aged 13 years and above are considered ‘adult’ and are managed by adult medicine. There is no upper age limit. Exclusion Criteria- Patients with congenital valvular heart diseases and cor pulmonale are excluded in the study. RESULTS The incidence of acquired valvular heart disease is higher in the age group of 31-40 years (32% followed by 21-30 years age group (28%. Our study also revealed relatively higher incidence of acquired valvular heart disease among the age groups of 51-60 years and above 60 years, which is due to a relatively higher incidence of mitral regurgitation due to ischaemic heart disease in this same age group. CONCLUSION Out of 100 cases studied mitral valve involvement was noted in 56 cases

    Since 1973, more than 75 patients with hypocomplementemic urticarial vasculitis syndrome (HUVS) were reported, but valvular heart disease does not seem to have been noted in these patients. Since 1993, however, five patients with HUVS accompanied by Jaccoud's arthropathy (JA) were found to have serious valvular heart disease. To characterize the cardiac valvulopathy of the third patient with HUVS/JA to have undergone valve replacement, this study included the use of routine and special tissue stains, as well as immunohistochemical staining. We compared gross and histologic findings of this patient's valve to those of two other patients with this complex syndrome who underwent valve replacement. Pathologic findings of these latter two patients were described in separate earlier reports. Histologic examination of the resected valves in all three patients showed an acute necrotizing endocarditis and fibrin deposition on the surface of valve leaflets. Beneath the surfaces of the leaflets, there was evidence of chronic inflammation, consisting of lymphocytes and histiocytes. A fibrocalcific degenerative change was also present in all three valves. Positive staining for IgG, IgA, IgM, and light-chain determinant-bearing proteins was detected primarily at the valve surface in special studies of the aortic valve of the patient described in the current report. Patients with HUVS and associated JA should be evaluated for the presence of valvular heart disease. The latter is probably a nonrheumatic, inflammatory, and degenerative process, mediated by immune complex, as well as cellular immune mechanisms.

    With the development of invasive medical procedures, an increasing number of healthcare-associated infective endocarditis cases have been reported. In particular, non-nosocomial healthcare-associated infective endocarditis in outpatients with recent medical intervention has been increasingly identified. A 66-year-old man with diabetes mellitus and a recent history of intermittent urethral self-catheterization was admitted due to a high fever. Repeated blood cultures identified Pseudomonas aeruginosa, and transesophageal echocardiography uncovered a new-onset severe aortic regurgitation along with a vegetative valvular structure. The patient underwent emergency aortic valve replacement surgery and was successfully treated with 6 weeks of high-dose meropenem and tobramycin. Historically, most cases of P. aeruginosa endocarditis have occurred in the right side of the heart and in outpatients with a history of intravenous drug abuse. In the case presented, the repeated manipulations of the urethra may have triggered the infection. Our literature review for left-sided P. aeruginosa endocarditis showed that non-nosocomial infection accounted for nearly half of the cases and resulted in fatal outcomes as often as nosocomial cases. A combination therapy with anti-pseudomonal beta-lactams or carbapenems and aminoglycosides may be the preferable treatment. Medical treatment alone may be effective, and surgical treatment should be carefully considered. We presented a rare case of native aortic valve endocarditis caused by P. aeruginosa. This case illustrates the importance of identifying the causative pathogen(s), especially for outpatients with a recent history of medical procedures.

    Pacemaker-related fungal endocarditis is an uncommon and unexpected complication. It is associated with high mortality rates. Due to nonspecific clinical symptoms, negative blood culture and delays in obtaining appropriate imaging studies; late diagnosis is common with fungal endocarditis. Hereby we are reporting a rare case of pacemaker lead endocarditis due to Trichosporon species. In literature we did not find any case of pacemaker-related endocarditis due to Trichosporon species.

    To elucidate the limitation of mitral valve reconstruction, 53 mitral disease patients (Mitral stenosis: 29, Mitral regurgitation: 24) undergoing reoperation late after valve reconstruction were studied, taking account of valvular lesions at initial operation. Reoperation rate after open mitral commissurotomy for mitral stenosis was higher in the patients with valvular regurgitation at initial operation than in those with severe subvalvular lesions or calcified valve. Reoperation rate for mitral regurgitation after mitral valvuloplasty was higher in the patients with stenotic fibrous degeneration or dilated annulus at initial operation than in those with torn chorda. Thus, these findings suggest that combined lesion of stenosis and regurgitation at initial operation may affect the reoperation rate in patients undergoing mitral valve reconstruction for either mitral stenosis or mitral regurgitation. Different approaches to the mitral valve through the left atrium and various techniques of the atriotomy have been practiced according to the need for a particular patients. The left atrium and the mitral valve can be exposed through median sternotomy followed by biatrial atriotomy or transplant approach. A correct approach and good exposure plays a key role in the success of redo surgical procedure for mitral valve disease.

    A case of primary infectious endocarditis with the lesion of mitral valve in a pregnant woman is reported The diseases was caused by meticillin-resistant Staphylococcus aureus. Special attention is given to inefficiency of beta-lactame antibiotics against this infection and beneficial effect of daptomycin therapy. This observation confirms literature data about high frequency of thromboembolic complications of S aureus-induced infectious endocarditis due to the production of various coagulases and von Willebrand factor-binding protein by these microorganisms. An increase of coagulation caused by S. aureus is mediated through activation of prothrombin, factor XIII, and fibrin-binding fibronectin. It requires prescription of direct thrombin inhibitor pradax that proved to yield good results in the treatment of our patient. It is concluded that infectious endocarditis in pregnant women is characterized by an atypical clinical picture due to impaired immunity associated with rapid progression of the process after delivery, high frequency of thromboembolic and DIC syndromes.

    2017-04-01

    Full Text Available A 74-year-old hemodialysis patient with a history of an atrial septum defect closure, coronary bypass surgery, and a St. Jude aortic prosthetic valve was diagnosed with pneumonia and volume overload. Blood cultures were positive for Listeria monocytogenes, and amoxicillin was given for 2 weeks. Immediately after discontinuation of amoxicillin, fever relapsed. Transthoracic and transesophageal echocardiography showed no sign of endocarditis. Given the fever relapse and 3 positive minor Duke criteria, an 18F-FDG PET-CT scan (18F-fluorodeoxyglucose-positron emission tomography-computed tomography scan was performed. This scan showed activity at the aortic root, proximal ascending aorta, and inferior wall of the heart, making Listeria monocytogenes endocarditis a likely explanation. Amoxicillin was given for 6 weeks with good clinical result. Diagnosing a life-threatening Listeria monocytogenes endocarditis can be challenging and an 18F-FDG PET-CT scan can be helpful.

    Valvular heart diseases still continue to be an important health problem. Surgical replacement of cardiac valves keeps a widely used treatment method for the present. However, the efficiency of minimal invasive and percutaneous methods targeted to repair and replacement of the diseased valves has been searched for nowadays. The first clinical experiences and early stage outcomes on the applicability of these methods are encouraging. Nevertheless, it should be kept in mind that percutaneous valvular interventions are at their development stages. Long term confidence and efficiency studies of these treatment modalities are needed. The present review emphasizes the studies on percutaneous techniques initiated in the treatment of valvular heart diseases.

    The aim of this retrospective multicenter study was to investigate the clinical manifestations, microbiological profile, echocardiographic findings and management strategies of infective endocarditis (IE) in Turkey. The study population consisted of 248 Turkish patients with IE treated at 13 major hospitals in Turkey from 2005 to 2012 retrospectively. All hospitals are tertiary referral centers, which receive patients from surrounding hospitals. Data were collected from the medical files of all patients hospitalized with IE diagnosed according to modified Duke Criteria. One hundred thirty seven of the patients were males. Native valves were involved in 158 patients while in 75 participants there was prosthetic valve endocarditis. Vegetations were detected in 223 patients (89%) and 52 patients had multiple vegetations. Mitral valve was the most common site of vegetation (43%). The most common valvular pathology was mitral regurgitation. The most common predisposing factor was rheumatic valvular disease (28%). Positive culture rate was 65%. Staphylococci were the most frequent causative microorganisms isolated (29%) followed by enterococci (11%). In-hospital mortality rate was 33%. Compared to IE in developed countries younger age, higher prevalence of rheumatic heart disease, more frequent enterococci infection and higher rates of culture negativity were other important aspects of IE epidemiology in Turkey.

    Infectious endocarditis remains both a diagnostic and a treatment challenge. A positive outcome depends on a rapid diagnosis, accurate risk stratification, and a thorough follow-up. Imaging plays a key role in each of these steps and echocardiography remains the cornerstone of the methods in use. The technique of both transthoracic echocardiography and transoesophageal echocardiography has been markedly improved across the last decades and most recently three-dimensional real-time echocardiography has been introduced in the management of endocarditis patients. Echocardiography depicts structural changes and abnormalities in the heart, but it does not uncover the underlying pathophysiological processes at the cellular or molecular level. This problem is addressed with introduction of new molecular imaging methods as (18)F-fluorodesoxyglucose ((18)F-FDG) PET-CT and single photon emission computed tomography fused with conventional CT (SPECT/CT). Of these methods, (18)F-FDG PET-CT carries the best promise for a future role in endocarditis. But there are distinct limitations with both SPECT/CT and (18)F-FDG PET-CT which should not be neglected. MRI and spiral CT are methods primarily used in the search for extra cardial infectious foci. A flowchart for the use of imaging in both left-sided and right-sided endocarditis is suggested.

    Full Text Available The present case report describes the clinical course of a patient who presented with Cardiobacterium hominis endocarditis. A review of the literature follows the case presentation. C hominis, a fastidious Gram-negative bacillus, is a member of the HACEK group of microorganisms (Haemophilus species, Actinobacillus actinomycetemcomitans, C hominis, Eikenella corrodens and Kingella kingae. Endocarditis caused by C hominis is uncommon and generally follows a subacute course. Patients may present with constitutional symptoms, symptoms related to valvular destruction or symptoms secondary to embolic events. Diagnosis requires identification of the pathogen from blood or vegetation by either culture or molecular techniques. Blood cultures may require prolonged incubation, highlighting the importance of incubating blood cultures for at least two to three weeks in patients with suspected endocarditis. In the past, C hominis was generally sensitive to penicillin. However, reports of beta-lactamase-producing C hominis have appeared in the literature over the past decade. The current recommendation for first-line treatment is a third-generation cephalosporin (ceftriaxone for four weeks (six weeks if a prosthetic valve is in place.

    Acute infective endocarditis is a potentially life-threatening disease. Its outcome strongly depends on systemic embolization and extracardiac infections. When present, these conditions usually lead to a more aggressive therapeutic approach. However, the diagnosis of peripheral septic embolism is very challenging. {sup 18}F-Fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT has proven to be accurate for the detection of inflammatory diseases and occult infections. The aim of this study was to assess the added value of {sup 18}F-FDG PET/CT in the detection of extracardiac embolisms in the evaluation of patients with suspected valvular endocarditis (VE). Seventy-one patients with suspected infective endocarditis, enrolled between June 2010 and December 2012, underwent {sup 18}F-FDG PET/CT with the standard procedure on a dedicated PET/CT scanner. Extracardiac findings were subsequently evaluated with other imaging procedures. Of the 71 patients with suspicion of infective endocarditis, we found unexpected extracardiac findings in 17 patients (24 %) without any clinical suspicion. Extracardiac findings were subsequently evaluated with other imaging procedures. PET/CT detected unexpected extra sites of infection in 24 % of cases, leading to changes in therapeutic management in a very relevant percentage of patients. These findings may have important therapeutic implications. (orig.)

    Left-sided valvular lesions are commonly associated with acute and chronic coronary syndromes. Ischemic mitral regurgitation is well described in the literature. We report a case of acute ischemic right-sided valvular disease in which the presenting symptom of an infarction was severe tricuspid regurgitation. This rare entity is usually caused by distortion of the valve apparatus due to underlying wall motion abnormalities. In conclusion, tricuspid regurgitation is an important yet uncommon presentation of acute ischemia that requires a high degree of suspicion for diagnosis.

    Full Text Available Infective endocarditis (IE is a unique diagnostic and therapeutic challenge. It is a severe disease, fatal before penicillin discovery. Atypical presentations frequently led to delayed diagnosis and poor outcome. There was little information about the natural history of the vegetations during medical treatment or the relation of morphologic changes in vegetation to late complications. Application of a new diagnostic criteria and echocardiography, increased the number of definite diagnosis. Trans-thoracic and trans-esophageal echocardiography had an established role in the management of patients with IE. The evolution of vegetation size, its mobility, and consistency, the extent of the disease, and the severity of valvular regurgutation were related to late complications. With therapeutic options including modern antibiotic treatment and early surgical intervention IE turned out to be a curable disease. Reduction in mortality also depended on prevention. Antibiotic prophylaxis of IE was important, but low mortality was also the result of early treatment, especially in the event of early recognition of symptoms and signs of the disease.

    Stress echo has already been validated in some forms of valvular heart disease, especially in calcific aortic stenosis with low cardiac output and dynamic mitral regurgitation (MR) of valvular heart disease. Stress Doppler haemodynamics is a term used to differentiate these new indications from that of segmental wall analysis of the left atrium in ischaemic heart disease. In calcific aortic stenosis with low output, the haemodynamics with low dose dobutamine allows assessment of the real severity of the aortic stenosis and identification of the rare cases with mild stenosis: the principal indication remains the assessment of operative risk and long-term prognosis by the study of left ventricular contractile reserve. In cases of ischaemic left ventricular systolic dysfunction, the presence of mild mitral regurgitation (regurgitant surface area >20 mm2 at rest) is a poor prognostic factor. The dynamic character of mitral regurgitation is related to left ventricular remodelling which leads to deformation of the valvular apparatus (mitral tenting). Dynamic mitral regurgitation (regurgitant orifice area >13 mm2 on exercise) is a powerful prognostic factor, the role of which has recently been demonstrated in the genesis of acute pulmonary oedema. the other indications of stress haemodynamics are under validation, mainly the assessment of exercise capacity and valvular compliance in mitral stenosis or asymptomatic aortic stenosis.

    Surgical valve replacement represents the treatment of choice for symptomatic and severe valvular heart disease. However, the operative risk is increased in presence of advanced age and comorbidities, therefore such patients are often not deemed suitable for surgical treatment. Recently, percutaneous valve replacement has emerged as an optional treatment for such patients, particularly for treating severe aortic stenosis and severe mitral regurgitation.

    2015-11-26

    Infective endocarditis (IE) is a life-threatening condition with adverse consequences and increased mortality, despite improvements in treatment options. Diagnosed patients usually require a prolonged course of antibiotics, with up to 40-50% requiring surgery during initial hospital admission. We report a case of a 42-year-old intravenous drug user who presented feeling generally unwell, with lethargy, rigours, confusion and a painful swollen right leg. He was subsequently diagnosed with Proteus mirabilis endocarditis (fulfilling modified Duke criteria for possible IE) and deep vein thrombosis (DVT). He was successfully treated with single antibiotic therapy without needing surgical intervention or requiring anticoagulation for his DVT. Proteus endocarditis is extremely uncommon, with a limited number of case reports available in the literature. This case illustrates how blood cultures are invaluable in the diagnosis of IE, especially that due to unusual microorganisms. Our case also highlights how single antibiotic therapy can be effective in treating Proteus endocarditis. 2015 BMJ Publishing Group Ltd.

  17. Erysipelothrix Rhusiopathiae Endocarditis and Presumed Osteomyelitis

    Full Text Available Erysipelothrix rhusiopathiae is known to cause infections in humans following exposure to decaying organic matter or animals colonized with the organism, such as swine and fish. Invasive infections with this organism are unusual and are manifested primarily as infective endocarditis. The present report is believed to be the first to report a case of E rhusiopathiae endocarditis and presumptive osteomyelitis. E rhusiopathiae appears to have intrinsic resistance to vancomycin. Because vancomycin is often used empirically for the treatment of endocarditis, rapid differentiation of E rhusiopathiae> from other Gram-positive organisms is critical. In patients with endocarditis caused by a Gram-positive bacillus and epidemiological risk factors for E rhusiopathiae exposure, empirical treatment with vancomycin should be reconsidered.

    Background Little is known about the magnitude of the association between infective endocarditis and cancer, and about the natural history of cancer patients with concomitant diagnosis of infective endocarditis. Methods We used the SEER-Medicare linked database to identify individuals aged 65 years or more diagnosed with colorectal, lung, breast, or prostate cancer, and without any cancer diagnosis (5% random Medicare sample from SEER areas) between 1992–2009. We identified infective endocarditis from the ICD-9 diagnosis of each admission recorded in the Medpar file and its incidence rate 90 days around cancer diagnosis. We also estimated the overall survival and CRC-specific survival after a concomitant diagnosis of infective endocarditis. Results The peri-diagnostic incidence of infective endocarditis was 19.8 cases per 100,000 person-months for CRC, 5.7 cases per 100,000 person-months for lung cancer, 1.9 cases per 100,000 person-months for breast cancer, 4.1 cases per 100,000 person-months for prostate cancer and 2.4 cases per 100,000 person-months for individuals without cancer. Two-year overall survival was 46.4% (95% CI 39.5, 54.5%) for stage I–III CRC patients with concomitant endocarditis and 73.1% (95% CI 72.9, 73.3%) for those without it. Conclusion In this elderly population, the incidence of infective endocarditis around CRC diagnosis was substantially higher than around the diagnosis of lung, breast and prostate cancers. A concomitant diagnosis of infective endocarditis in patients with CRC diagnosis is associated with shorter survival. PMID:26683995

    Infective endocarditis caused by Streptococcus bovis is known to be associated with colorectal malignancy. Other less common streptococci, specifically Streptococcus sanguis, can be similarly associated with gastrointestinal carcinoma. We present a case of disseminated colorectal carcinoma occurring after a confirmed S sanguis endocarditis, that required mitral valve surgery. There may be a need for gastrointestinal surveillance in patients presenting with bacteraemia caused by less common streptococci.

    2010-05-11

    Valvular heart disease, particularly aortic stenosis and mitral regurgitation, accounts for a large proportion of cardiology practice, and their prevalence is predicted to increase. Management of the asymptomatic patient remains controversial. Biomarkers have been shown to have utility in the management of cardiovascular disease such as heart failure and acute coronary syndromes. In this state-of-the-art review, we examine the current evidence relating to natriuretic peptides as potential biomarkers in aortic stenosis and mitral regurgitation. The natriuretic peptides correlate with measures of disease severity and symptomatic status and also can be used to predict outcome. This review shows that natriuretic peptides have much promise as biomarkers in common valvular heart disease, but the impact of their measurement on clinical practice and outcomes needs to be further assessed in prospective studies before routine clinical use becomes a reality.

    Acute rheumatic fever and rheumatic heart disease remain major global health problems. Although strategies for primary and secondary prevention are well established, their worldwide implementation is suboptimum. In patients with advanced valvular heart disease, mechanical approaches (both percutaneous and surgical) are well described and can, for selected patients, greatly improve outcomes; however, access to centres with experienced staff is very restricted in regions that have the highest prevalence of disease. Development of diagnostic strategies that can be locally and regionally provided and improve access to expert centres for more advanced disease are urgent and, as yet, unmet clinical needs. We outline current management strategies for valvular rheumatic heart disease on the basis of either strong evidence or expert consensus, and highlight areas needing future research and development.

  7. Timing for Pacing after Acquired Conduction Disease in the Setting of Endocarditis

    Directory of Open Access Journals (Sweden)

    Daniel Brancheau

    2015-01-01

    Full Text Available A 53-year-old gentleman with a history of a mechanical aortic valve presented to the emergency department complaining of a sudden right-sided abdominal pain. He was found to have atrioventricular dissociation on his initial electrocardiogram and his blood cultures grew Streptococcus viridans. The suspicion for endocarditis with periaortic abscess was high so a transthoracic echocardiogram was performed and showed a mass in the left ventricular outflow tract. For better visualization, a transesophageal echocardiogram was recommended and revealed a bileaflet mechanical aortic valve with perivalvular abscess and valvular vegetation as well as severe eccentric paravalvular aortic regurgitation. After sterilization, the patient underwent a successful surgery. Postoperatively, he remained in complete heart block and a permanent pacemaker placement was performed after complete sterilization. He tolerated the procedure well and was discharged home in a stable condition. Perivalvular abscess is one of the most common cardiac complications of infective endocarditis and is associated with an increased risk of mortality. It is imperative to have appropriate treatment guidelines established. However, because of the relative nature of the disease process and the acuity at which intervention needs to be done, a true assessment of the duration of antibiotic therapy prior to surgical intervention, timing of pacemaker placement, and the type of pacemaker is controversial.

    The incidence of infective endocarditis is underestimated in solid organ transplant recipients. The spectrum of pathogens is different from the general population. The authors report the successful treatment of a 58-year-old woman with infective endocarditis caused by atypical microorganism and presented with atypical manifestations. Past history of the patient included alcoholic liver cirrhosis and cadaver liver transplantation in February 2000. One year after liver transplantation hepatitis B virus infection was diagnosed and treated with antiviral agents. In July 2007 hemodialysis was started due to progressive chronic kidney disease caused by calcineurin toxicity. In November 2013 the patient presented with transient aphasia. Transesophageal echocardiography revealed vegetation in the aortic valve and brain embolization was identified on magnetic resonance images. Initial treatment consisted of a 4-week regimen with ceftriaxone (2 g daily) and gentamycin (60 mg after hemodialysis). Blood cultures were all negative while serology revealed high titre of antibodies against Chlamydia pneumoniae. Moxifloxacin was added as an anti-chlamydial agent, but neurologic symptoms returned. After coronarography, valvular surgery and coronary artery bypass surgery were performed which resulted in full clinical recovery of the patient.

A 25-year-old man with an extensive history of intravenous drug abuse presents to the hospital with worsening shortness of breath and fevers for two weeks. In the emergency department, he was initially provided breathing treatments including ipratropium/albuterol and methylprednisolone. As the patient still required supplemental oxygen, a chest radiograph was performed to evaluate for an underlying infectious etiology. However, the chest radiograph portrayed an enlarged cardiomediastinal silhouette in a “water-bottle” appearance and obscuration of the hilar vessels (Figure 1. Given these findings, there was a high concern for a pericardial effusion, and the physicians opted for further cross-sectional imaging. The contrast enhanced computed tomography (CT images confirmed the aforementioned diagnosis (Figure 2.

    The RIFLE classification, which defines three grades of increasing severity of acute kidney injury--risk (RIFLE R), injury (RIFLE I) and failure (RIFLE F), and two outcome classes (L, loss) and E (end-stage kidney disease)--represents a valuable method for evaluating acute renal failure. Risk factors for acute kidney injury (AKI) according to the RIFLE criteria and for operative mortality were identified in patients undergoing valvular procedures. A single-center prospective cohort study of 1424 patients who were not receiving renal replacement therapy preoperatively was conducted between January 2004 and December 2007. A total of 100 variables was collected from each patient. The main features were: mean age 61.9 +/- 12.9 years (range: 15-88 years), 47% females, 6% endocarditis, 11% redo surgery, 8% urgent/emergent surgery, 30% combined procedures, 5% complex, and 16% associated coronary artery bypass grafting (CABG). The overall AKI prevalence was 10%, with RIFLE scores of I or F being detected in 8% and continuous veno-venous hemofiltration being required in 5%. Risk factors for AKI were age (OR 1.03; 95% CI 1.14-4.15), time of extracorporeal circulation (ECC) (OR 1.09; 95% CI 1.005-1.013), redo procedure (OR 2.35; 95% CI 1.42-3.8), chronic kidney disease (OR 3.2; 95% CI 1.6-6.1), and blood transfusion (OR 3.8; 95% CI 2.5-6.5). The transfusion of leukodepleted blood exerted a protective effect on AKI development (OR 0.6; 95% CI 0.4-0.9). The average overall hospital mortality was 4.8%. Risk factors for operative mortality included: ECC time (OR 1; 95% CI 1.002-1.014), age (OR 1.043; 95% CI 1.01-1.07), chronic kidney disease (OR 4.8; 95% CI 2.2-10.6), blood transfusion (OR 6.43; 95% CI 2.8-14.7), surgical priority (OR 6.5; 95% CI 2.8-14.7), RIFLE class I (OR 11.9; 95% CI 5.5-25.7), and RIFLE class F (OR 30; 95% CI 8.1-111.7).

Botkin City Clinical Hospital in 2000-2011 and 92 ones admitted in 1985-1977.

Over half of the patients are socially unadapted C-peptide level is of diagnostic value for the assessment of inflammation activity, precursors of natriuretic peptide can be used to detect preclinical and clinical stages of cardiac failure related to infectious endocarditis. There is correlation between severity of inflammation and myocardial dysfunction. Early surgical intervention in the absence of effect of combined antibacterial therapy improves prognosis. Morphological studies of inflammation-related changes in myocardium, destruction of cardiomyocytes, dystrophic processes, and fibrosis play an important role in the development of cardiac insufficiency and prognosis of infectious endocarditis.

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

    Infectious endocarditis in children requires prolonged antibiotic therapy. In adults, antibiotics administrated subcutaneously such as teicoplanin are an alternative to intravenous treatment. We report the use of subcutaneous teicoplanin, after an initial antibiotic treatment administrated intravenously, for 2 children treated for infectious endocarditis following an initial cardiac surgery. Serum concentrations of teicoplanin were within the target range after the adaptation in the teicoplanin subcutaneous dosages. The treatment was effective for both cases. No specific side effects related to the treatment were reported. Subcutaneous administration could be used for prolonged antibiotic therapy for the treatment of infectious endocarditis in children, after an initial intravenous treatment. Variability of the bioavailability of antibiotics administrated subcutaneously requires regular testing. Prospective, randomized trials comparing intravenous and subcutaneous administration of teicoplanin should be conducted to assess the efficacy and safety of this treatment.

    Full Text Available Endogenous endophthalmitis is a rare ocular infection affecting the vitreous and/or aqueous humours. It is associated with poor visual prognosis and its commonest endogenous aetiology is infective endocarditis. The causative organisms of endogenous endophthalmitis complicating endocarditis are mainly Group A or B streptococci. The identification of Group C and G streptococci such as Streptococcus dysgalactiae is comparatively uncommon and has only been reported in a few case reports or series. We therefore report a case of infective endocarditis caused by Streptococcus dysgalactiae first presenting with endogenous endophthalmitis, the most likely source being bilateral feet osteomyelitis in a patient with type I diabetes. The patient was treated with a course of intravenous benzylpenicillin, intravitreal antibiotics, bilateral below knee amputations and mitral valve replacement. She survived all surgical procedures and regained partial visual acuity in the affected eye.

    Unlike other viridans streptococci, members of the "Streptococcus milleri group" are often associated with abscess formation, but are only rare causes of infective endocarditis. Although it has been shown that almost all S. intermedius isolates and most S. constellatus isolates, but only 19% of S. anginosus isolates, were associated with abscess formation, no report has addressed the relative importance of the 3 species of the "S. milleri group" in infective endocarditis. During a 5-year period (April 1997 through March 2002), 6 cases of "S. milleri" endocarditis (out of 377 cases of infective endocarditis), that fulfil the Duke's criteria for the diagnosis of infective endocarditis, were encountered. All 6 "S. milleri" isolates were identified as S. anginosus by 16S ribosomal RNA (rRNA) gene sequencing. Three patients had underlying chronic rheumatic heart disease and 1 was an IV drug abuser. Five had monomicrobial bacteremia, and 1 had polymicrobial (S. anginosus, S. mitis, Granulicatella adiacens, and Slackia exigua) bacteremia. Two patients died. None of the 6 isolates were identified by the Vitek system (GPI) or the API system (20 STREP) at >95% confidence. All 6 isolates were sensitive to penicillin G (MIC 0.008-0.064 microg/mL), cefalothin, erythromycin, clindamycin, and vancomycin. Accurate identification to the species level, by 16S rRNA gene sequencing, in cases of bacteremia caused by members of the "S. milleri group", would have direct implication on the underlying disease process, hence guiding diagnosis and treatment. Infective endocarditis should be actively looked for in cases of monomicrobial S. anginosus bacteremia, especially if the organism is recovered in multiple blood cultures.

    Full Text Available Objetivo: estudiar las características clínicas, epidemiológicas y microbiológicas, así como el tratamiento médico quirúrgico de los pacientes ingresados con el diagnóstico de endocarditis infecciosa, con el propósito de profundizar en su estudio y contribuir a un mejor tratamiento a estos pacientes. Métodos: se estudiaron 24 pacientes procedentes de todo el país, egresados con el diagnóstico de endocarditis infecciosa. Los datos fueron recogidos de las historias clínicas procedentes del archivo del Hospital "William Soler", y de la base de datos del servicio de cirugía del cardiocentro. Se determinó la frecuencia de las diferentes manifestaciones de la endocarditis infecciosa según: grupos etarios, factores de riesgo, y los datos clínicos, de laboratorio y microbiológicos más frecuentes. Además, se determinó la toma valvular predominante, la etiología y su respuesta a los antibióticos. Resultados: el grupo de edad más afectado fue entre 5 y 18 años; la cardiopatía previa fue el factor de riesgo predominante; los síntomas y signos más frecuentes fueron la fiebre, la anorexia y la pérdida de peso. La insuficiencia cardiaca y el embolismo pulmonar fueron complicaciones frecuentes. La mayoría de los pacientes tuvo una eritrosedimentación acelerada, y la cuarta parte de los casos presentaron hemocultivos negativos. Las válvulas aórtica y mitral resultaron las más afectadas, y el curso clínico que predominó fue el subagudo. En casi la mitad de los pacientes la infección tuvo un origen nosocomial. Los antimicrobianos más utilizados fueron la amikacina, la vancomicina y la ceftriaxona. Conclusiones: la endocarditis infecciosa es poco frecuente en nuestra institución, ocurre más a menudo en relación con las cardiopatías congénitas. Los hechos clínicos más constantes fueron la fiebre y el antecedente de cardiopatía previa.

    Infective endocarditis (IE) is a severe disease with high mortality rate. Cytokines participate in its pathogenesis and may contribute to early diagnosis improving the outcome. This study aimed to evaluate the cytokine profile in IE. Serum concentrations of interleukin (IL)-1β, IL-6, IL-8, IL-10, IL-12 and tumor necrosis factor (TNF)-α were measured by cytometric bead array (CBA) at diagnosis in 81 IE patients, and compared with 34 healthy subjects and 30 patients with non-IE infections, matched to the IE patients by age and gender. Mean age of the IE patients was 47±17 years (range, 15–80 years), and 40 (50%) were male. The IE patients had significantly higher serum concentrations of IL-1β, IL-6, IL-8, IL-10 and TNF-α as compared to the healthy individuals. The median levels of IL-1β, TNF-α and IL-12 were higher in the IE than in the non-IE infections group. TNF-α and IL-12 levels were higher in staphylococcal IE than in the non-staphylococcal IE subgroup. There was a higher proportion of both low IL-10 producers and high producers of IL-1β, TNF-α and IL-12 in the staphylococcal IE than in the non-staphylococcal IE subgroup. This study reinforces a relationship between the expression of proinflammatory cytokines, especially IL-1β, IL-12 and TNF-α, and the pathogenesis of IE. A lower production of IL-10 and impairment in cytokine network may reflect the severity of IE and may be useful for risk stratification. PMID:26225421

    Both intense endurance training and valvular regurgitation place a volume load on the right and left ventricles, potentially leading to dilation, but their effects in combination are not well-known. The purpose of this case series is to describe the combined volume load of intense endurance athletic training and regurgitant valvular disease as well as the challenging assessment of each component's cardiovascular effect. In this article, the clinical course of three elite endurance athletes with congenital valvular disease were reviewed. A swimmer with aortic regurgitation, a cyclist with aortic regurgitation, and a cyclist with pulmonary regurgitation were found to have severe dilation of the associated ventricles despite continuing to train at an elite level without symptoms. Because of the cumulative effects of endurance training and valvular regurgitation, each athlete manifested ventricular dilation out of proportion to their valvular disease and symptoms. Although the effects of congenital valvular disease and athletic remodeling on ventricular dilation have been thoroughly studied individually, their cumulative effect is not well understood. This complicates the assessment of athletes with valvular regurgitation and underscores the need for athlete-specific recommendations for valve replacement.

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

    Valvular heart disease is a growing public health problem, with an increasing prevalence due to an ageing population. Despite advances, the medical management of symptomatic valvular heart diseases remains suboptimal, necessitating surgical correction. The challenge remains in identifying an asymptomatic or mildly symptomatic patient who will benefit from timely surgery before irreversible changes in cardiac function have occurred. The potential risks of surgery versus watchful expectancy require careful decision-making. This review is a focused update on the existing guidelines and identifies the knowledge gaps and avenues of future research in the management of patients with valvular heart diseases PMID:27325921

    While valve surgery is an established form of treatment in significant valvular heart diseases, open heart surgery is not possible for all patients, owing to the risks involved. The incidence of valvular heart diseases increases sharply with age, and it is common that operative risks are overestimated due to age and associated diseases. This review deals with two catheter therapies that are in clinical use for valvular heart diseases: insertion of aortic valve prosthesis through a catheter and treatment of mitral valve insufficiency by clip implantation via the transvenous access.

  19. Spondylodiscitis and endocarditis caused by S. vestibularis

    Full Text Available Streptococcus vestibularis is a recently described member of the viridans group that was first isolated from the vestibular mucosa of the human oral cavity and described as a new species in 1988. It has been rarely associated with human infections. In few papers, it has been reported as a causal agent of systemic infection in immunosupressed adults and in those with other severe underlying diseases, like coronary valve diseases. A 65-year-old woman was admitted to the hospital with complaints of fever for three months, general malaise, effort dyspnea, weight loss, back pain and myalgia. Both native aortic valve endocarditis and spondylodiscitis due to Streptococcus vestibularis were detected. The patient was successfully treated with intravenous potassium penicillin G and gentamicin for six weeks, followed by oral amoxicillin for three months, in addition to aortic valve replacement. In all patients with spondylodiscitis, infective endocarditis should be considered, particularly in patients with heart valve disease history, since spondylodiscitis may be the presenting sign of an infective endocarditis. Cardiac valve replacement surgery should be performed if the course of fever and inflammatory syndrome is unfavorable after appropriate antibiotic treatment. We report the first case with both native aortic valve endocarditis and spondylodiscitis due to Streptococcus vestibularis.

Demographic data, clinical severity scores, microbiological and echocardiographic data, hospital mortality and complications. Out of 102 patients diagnosed with endocarditis, 38 (37%) were admitted to Intensive Care. Compared with those patients not admitted to the ICU, these subjects suffered more frequent mitral valve alterations (OR= 7.13; 95%CI: 2.12-24; p= 0.002) and cerebral embolism (OR= 3.89; 95%CI: 1.06-14.3; p= 0.041). In turn, mortality was greater (42.1% vs 18.8%, p= 0.011), as was the proportion of emergency surgeries (45.8% vs 5.9%, pendocarditis require admission to the Intensive Care Unit, presenting a much poorer prognosis.

    2009-01-01

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

    2017-08-24

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

    2011-01-01

    Full Text Available Endocarditis due to Achromobacter species is a rare, yet serious, endovascular infection. Achromobacter species infective endocarditis is associated with underlying immunodeficiencies or prosthetic heart valves and devices. A case of prosthetic pulmonary valve endocarditis secondary to Achromobacter xylosoxidans subspecies denitrificans is described in the present report. This life-threatening infection was successfully treated with combined valve replacement and prolonged antibiotic therapy. A Medline/PubMed literature review of Achromobacter endocarditis was also performed. Achromobacter species are an uncommon, yet important, cause of nosocomial endocarditis. Given the significant associated morbidity and mortality, along with a high degree of intrinsic antibiotic resistance, Achromobacter species infective endocarditis remains a clinical treatment challenge.

    The aim of this prospective study was to investigate the agreement in findings between ECG-gated CT and transoesophageal echocardiography (TEE) in patients with aortic prosthetic valve endocarditis (PVE). Twenty-seven consecutive patients with PVE underwent 64-slice ECG-gated CT and TEE and the results were compared. Imaging was compared with surgical findings (surgery was performed in 16 patients). TEE suggested the presence of PVE in all patients [thickened aortic wall (n = 17), vegetation (n = 13), abscess (n = 16), valvular dehiscence (n = 10)]. ECG-gated CT was positive in 25 patients (93 %) [thickened aortic wall (n = 19), vegetation (n = 7), abscess (n = 18), valvular dehiscence (n = 7)]. The strength of agreement [kappa (95 % CI)] between ECG-gated CT and TEE was very good for thickened wall [0.83 (0.62-1.0)], good for abscess [0.68 (0.40-0.97)] and dehiscence [0.75 (0.48-1.0)], and moderate for vegetation [0.55 (0.26-0.88)]. The agreement was good between surgical findings (abscess, vegetation and dehiscence) and imaging for ECG-gated CT [0.66 (0.49-0.87)] and TEE [0.79 (0.62-0.96)] and very good for the combination of ECG-gated CT and TEE [0.88 (0.74-1.0)]. Our results indicate that ECG-gated CT has comparable diagnostic performance to TEE and may be a valuable complement in the preoperative evaluation of patients with aortic PVE. (orig.)

    Full Text Available Endocarditis is an inflammatory state of the endothelium that promotes thrombus formation and tissue damage on the surface of heart valves. Recent studies have reported endocarditis mortality rates ranging from 12% to 46% (2008. The Streptococcus gordonii is a normal inhabitant of the human oral cavity. It is a component of the microbial communities responsible of plaque formation, associated with dental caries and also regarded as the main causative agent in the development of subacute bacterial endocarditis (SBE.

  14. Diagnostic approach to assessment of valvular heart disease using MRI—Part I: a practical approach for valvular regurgitation

    2012-01-01

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

    Full Text Available Infective endocarditis is a common clinical problem in industrialized countries. Risk factors include abnormal cardiac valves, a history of endocarditis, intracardiac devices, prosthetic valves and intravenous drug use. We report a case of polymicrobial infective endocarditis in a 33 year-old female with a history chronic heroin use caused by Neisseria sicca and Haemophilus parainfluenzae. We believe the patient was exposed to these microbes by cleansing her skin with saliva prior to injection. Pairing a detailed history with the consideration of atypical agents is crucial in the proper diagnosis and management of endocarditis in patients with high-risk injection behaviors.

    Oral health is of particular importance in patients with heart valve diseases because of the risk of infective endocarditis. Recommendations for antibiotic prophylaxis before dental procedures have been restricted, but the modalities of oral evaluation and dental care are not detailed in guidelines. Therefore, a multidisciplinary working group reviewed the literature to propose detailed approaches for the evaluation and management of buccodental status in patients with valvular disease. Simple questions asked by a non-dental specialist may draw attention to buccodental diseases. Besides clinical examination, recent imaging techniques are highly sensitive for the detection of inflammatory bone destruction directly related to oral or dental infection foci. The management of buccodental disease before cardiac valvular surgery should be adapted to the timing of the intervention. Simple therapeutic principles can be applied even before urgent intervention. Restorative dentistry and endodontic and periodontal therapy can be performed before elective valvular intervention and during the follow-up of patients at high risk of endocarditis. The detection and treatment of buccodental foci of infection should follow specific rules in patients who present with acute endocarditis. Implant placement is no longer contraindicated in patients at intermediate risk of endocarditis, and can also be performed in selected high-risk patients. The decision for implant placement should follow an analysis of general and local factors increasing the risk of implant failure. The surgical and prosthetic procedures should be performed in optimal safety conditions. It is therefore now possible to safely decrease the number of contraindicated dental procedures in patients at risk of endocarditis. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

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

    Full Text Available Takayasu’s arteritis (TA is a chronic inflammatory disease that affects large vessels, predominantly the aorta and main branches, leading to vessel wall thickening, fibrosis and stenosis. Cardiac and vascular symptoms are also commonly present at disease onset. In TA with thoracic or abdominal involvement, although murmur can be present as a physical examination finding, the pulse difference may be absent. Here, we mention a case of TA who initially looked like infective endocarditis and had widespread thoracic murmur.

    Full Text Available AbstractBackground. Infectious endocarditis of the tricuspid valve is rare in non-intravenous drug users and patients without central venous devices. The most frequent causative agents are staphylococci, rarely other bacteria.Methods. We describe a case of a 57-year-old patient without history of drug abuse that was admitted to our hospital because of fever with chills, dry cough, loss of appetite and wasting lasting for a few months. He had a venous ulcer on the right foot and interdigital inflammation on both feet. Eikenella corrodens was isolated from blood cultures. Transthoracic echocardiography showed a large vegetation on the anterior leaflet of tricuspid valve. CT scan oh the thorax showed probable septic emboli. The patient was treated conservatively with prolonged double antibiotic regimen. During the treatment there were no further complications.Conclusions. In our patients a rare form of tricuspid valve endocarditis was confirmed, caused by Eikenella corrodens. The possibility of infectious endocarditis should always be considered in patients with prolonged fever, especially when a possible causative agent is isolated from blood cultures.

    To analyze the clinical manifestations, epidemiological features, pathogens, treatment and outcomes of 112 patients with infectious endocarditis. The clinical data were reviewed for all the patients with the diagnosis of infectious endocarditis in Nanfang Hospital over the period from 2002 to 2012. The average age of disease onset was 46∓17.1 years among these cases. Seventy patients (62.5%) had underlying cardiac conditions, including, in the order of frequency, rheumatic heart disease, congenital cardiovascular anomalies, and senile valve degeneration. Clinically the patients presented with fever, anemia, congestive heart failure, and embolism events, etc. Echocardiography found endocardial neoplasms in 105 cases, and the mitral valve was often involved. Blood culture yielded positive results in 61 cases, and the most common causative bacteria were Streptococcus (20.5%), Staphylococcus (19.6%) and Enterococcus (5.4%). Surgical intervention was performed in 78 cases. Ninety-one patients were cured or improved after comprehensive treatment, and 10 discontinued treatment for financial reasons; 11 died of cardiac failure (8 cases), pulmonary embolism (2 cases) and central nervous system events (1 case). Infectious endocarditis shows a significant change in the clinical profiles and its mortality remains high despite improved diagnostic and therapeutic procedures.

    Infectious endocarditis is a rare disease with high mortality. Epidemiological changes in recent years, the emergence of new risk factors, and the increasing use of intravasal prosthetic materials has led to changes in not only the clinical appearance of this disease but also in its diagnosis and treatment. Early diagnosis of infectious endocarditis is crucial. However, the often unspecific symptoms and the changes in its epidemiologic profile pose a challenge for the treating physician. This is especially true since the incidence of hospital-acquired, "nosocomial" cases of infectious endocarditis is increasing and often affects severely ill patients in intensive care units (ICU). There are diagnostic and therapeutic algorithms to guide the physician from an early diagnosis to an adequate treatment of the disease. In some critically ill patients, only surgery in combination with antimicrobial treatment may lead to complete eradication of the infectious disease. This review aims to subsume the guidelines, paying special attention to aspects that are important for intensive care and emergency doctors.

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

    To compare clinical complications and outcomes of infective endocarditis (IE) episodes caused by Staphylococcus aureus (S. aureus) and other most frequent aetiological agents (streptococci, enterococci, coagulase-negative staphylococci, and culture-negative IE). A total of 117 IE episodes assessed by all internal medicine services of a major teaching institution in the Czech Republic over an eight-year period were identified. We found that S. aureus IE episodes (n = 36) were significantly more associated with systemic embolism (41.7% vs 18.5%, P = 0.01), severe sepsis/septic shock (33.3% vs 3.7%, P < 0.0001), and in-hospital mortality (33% vs 12.3%, P = 0.01). No differences in local, structural, and/or functional complications (cardiac abscess formation, impaired integrity of the valvular apparatus, conduction disturbances, or incidence of heart failure) were observed between studied groups. Long-term survival estimates were significantly improved in patients with IE caused by agents other than S. aureus (13.78 median years vs 5.48 median years, P=0.03). IE episodes caused by S. aureus are associated with both increased short-term and long-term mortality. Of all the studied parameters, only systemic embolism and severe sepsis/septic shock predicted in-hospital mortality.

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

    Bentata, Yassamine

    2017-11-01

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

  1. Mycobacterium abscessus Endocarditis: A Case Report and Literature Review

    Full Text Available Infective endocarditis owing to Mycobacterium abscessus infection is rarely reported. Most cases of infective endocarditis caused by Mycobacterium abscessus are seen in patients after valve replacement. Although early surgical intervention is recommended and medical treatment with antibiotics according to the susceptibility to the pathogen, such as amikacin, imipenem, cefoxitin, quinolones and macrolides, are applied, the course of such endocarditis is usually subacute and often has fatal outcomes. The present case was a 29-year-old male patient who was an intravenous drug user who had recurrent endocarditis caused by Mycobacterium abscessus. Unusually, our reported case was infected on his native valve. However, we experienced recurrence despite antimicrobial therapy. For culture-negative endocarditis, physicians should consider the possibility of Mycobacterium abscessus infection and related treatment difficulties.

    Anti-phospholipid antibodies (APA) may involve heart and valvular heart disease seems to be the most common clinical manifestation. To study the prevalence and characteristics of valvular heart disease in a large patient population with anti-phospholipid syndrome (APS) and also to analyze the clinical and immunological profile of patients with valvular involvement compared with those without involvement. Patients and methods. Retrospective analysis of 113 patients diagnosed of APS. Eighty-one percent were females and the mean age was 39 years (SD:14). Sixty-two percent of patients were diagnosed of primary APS (70 patients) and the remaining 38% (43 patients) corresponded to patients with APS associated with systemic lupus erythematosus (SLE). The median follow-up of patients was 55 months (range: 7-144 months). The cardiologic assessment was performed by means of transthoracic echocardiogram. The study of anti-lupus anticoagulant (AL) was performed by means of coagulometric assays and measurement of anticardiolipin antibodies (aCL), anti-beta2 glycoprotein I (abeta2-PGI) and anti-prothrombin (aPT) by ELISA. The prevalence of valvular heart disease was 19%. The mitral valve was mostly involved (91%) and the most common structural abnormality corresponded to mitral insufficiency. Valvular replacement was required in 24% of patients. In the subgroup of patients with valvular heart disease, a significantly higher prevalence was observed in the following parameters: total thrombosis (71% versus 49%; p = 0.05), arterial thrombosis (57% versus 23%; p = 0.002), stroke (38% versus 13%; p = 0.01), trombocitopenia (71% versus 45%; p = 0.02), hemolytic anemia (29% versus 9%; p = 0.02), and livedo reticularis (48% versus 3%; p < 0.0001). As for immunological differences, only a higher prevalence of LA was found (81% versus 59%; p= 0.04) and abeta2-GPI (IgG isotype) (43% versus 22%; p = 0.05) in patients with valvular heart disease.

    Echocardiography is the method of choice for diagnostics and decision making in valvular heart diseases. It is a universally available diagnostic tool not limited by radiation exposure or toxicity of contrast agents. It is capable of displaying cardiac anatomy, function and blood flow allowing an integrative approach to diagnosing valvular heart diseases. Quantification of stenotic valve lesions by calculating the valve opening area is well established. On the other hand, quantification of valve regurgitation is more difficult as it relies on simplifications and assumptions on geometry of the regurgitation orifice and its boundaries. Three dimensional assessments of the regurgitation orifice and flow may improve the accuracy of grading of cardiac valve regurgitation.

We report a case of a 59-year-old woman, with  PVE and bacterial endocarditis (Streptococcus bovis successfully treated with linezolid. Linezolid is a bacteriostatic oxazolidinone antibiotic that has been proven to be effective for the treatment of patients with pneumonia, skin and soft tissue infections, and infections due to Gram-positive cocci. Linezolid is not yet recognised as a standard therapy for infective endocarditis, but its use becomes a necessity when infection is due to multidrug-resistant microorganisms.

We present a case report of a patient with relapsing brucellosis complicated with aortic valve endocarditis. The patient underwent valve replacement and required prolonged antibiotic treatment because of rupture of the noncoronary leaflet and development of congestive heart failure. Since the onset of endocarditis in patients with brucellosis is not known, proper follow-up is required in order to identify any late onset complications, especially in endemic areas.

Whether an exclusively antibiotic regimen is superior to surgical intervention is subject to ongoing debate. Current guidelines indicate when surgery is the preferred treatment, but decisions are often based on physician preferences. Surgery has shown to decrease the risk of short-term mortality in patients who present with specific symptoms or microorganisms; nevertheless even then it often remains unclear when surgery should be performed. In this review we i systematically reviewed the current literature comparing medical to surgical therapy to evaluate if surgery is the preferred option, ii performed a meta-analysis of studies reporting propensity matched analyses, and iii, briefly summarized the current indications for surgery.Keywords: endocarditis, surgery, antibiotics, review, meta-analysis, propensity analysis, mortality, complications

    Valvular dysfunction is as frequent as acute coronary syndromes in the pathogenesis of acute decompensated heart failure. The prevalence of relevant valvular dysfunction increases with age and reaches more than 10 % in patients over 75 years old. Guidelines and studies on the treatment of these patients, especially in an intensive care unit (ICU) setting are, however, scarce despite excellent guidelines for treatment of valvular heart disease in the general population. In the last decade a number of therapeutic alternatives became available when standard inotrope and vasopressor therapy fails to stabilize patients. These include balloon valvuloplasty in patients with severe aortic valve stenosis and assist devices, extracorporeal membrane oxygenation (ECMO) as well as mitral clipping. These therapeutic alternatives are to be considered as bridge to operation procedures in cases of shock due to valvular dysfunction, as hemodynamic stabilization and stabilization of organ function are essential to allow valve repair/replacement which is still considered to be the gold standard in this situation but is not always possible in the acute setting.

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

    Although Doppler echocardiography remains the most frequently used imaging modality for assessing valvular heart disease, the technique has a number of limitations that could affect the quality of imaging studies and make the results difficult to interpret. Cardiac magnetic resonance (CMR) imaging could be superior to echocardiography in a number of ways: for example, for assessing ventricular dimensions, volumes, function and mass, for quantifying valvular regurgitation, and for investigating areas of myocardial fibrosis and extracardiac structures. In carrying out these tasks, CMR uses a variety of pulse sequences that are specially created to obtain information on specific tissue characteristics or on particular aspects of blood flow through heart valves. This general review article focuses on the usefulness of CMR in the clinical diagnosis of valvular heart disease and reviews how the data acquired using the technique can be incorporated into algorithms for the clinical management of patients with significant valvular heart lesions.

    Background and Objectives. Valvular heart diseases are among the frequent causes of cardiac surgery. Some patients have a well-known rheumatic condition. Heart valves are fragile connective tissues which are vulnerable to any systemic autoimmune diseases. This study was designed to evaluate the frequency of rheumatological background in patients candidate for valvular heart surgery in Afshar Cardiovascular Center, Yazd, Iran. Methods. One hundred and twenty (120) patients candidate for valvular heart surgery were selected for this study. Careful history and physical examination were undertaken from rheumatological stand points. The most sensitive screening serologic tests were also assayed. Results. The result of this study showed that 53.3% were male and 46.6% were female with mean age of 48.18 ± 17.65 years old. 45.8% of the patients had history of nonmechanical joint disease, 14.2% had history of rheumatological conditions in their family, and 30% had history of constitutional symptoms. 29.8% had positive joint dysfunction findings in their physical examination while 25.8% had anemia of chronic disease. Positive Rheumatoid factor (RF), anticyclic citrullinated peptide (CCP, ACPA), C-reactive protein (CRP), antinuclear antibody (ANA), abnormal urine and elevated erythrocyte sedimentation rate (ESR) were 34, 2.5, 26.7, 4.2, 5, and 36.7%, respectively. Antineutrophil cytoplasmic antibody (ANCA) and antiphospholipid (APL) were positive in a few cases. Conclusion. The findings of this study show immunologic bases for most patients with valvular heart diseases candidate for surgery. Undifferentiated connective tissue diseases may play an important role in the pathophysiology of valvular damage. PMID:23304546

    A 46-year-old woman with sudden on set strong right flank pain was transferred to our hospital with the diagnosis of right renal infarction. Cardiac ultrasonography revealed a vegetation on the posterior cusp of the mitral valve, and the renal infarction was thought to be caused by renal artery embolism from infective endocarditis. Since the vegetation remained after antimicrobial therapy as conservative management, the patient was surgically treated by mitral annuloplasty. It has been known that infective endocarditis can cause renal infarction. Infective endocarditis requires immediate and adequate treatment because of high mortality. Therefore, the appropriate diagnosis of infective endocarditis is needed for patients with renal infarction without any other disorder causing renal infarction.

    The diagnosis of infective endocarditis is often delayed in clinical practice. Timely diagnosis and rapid antibiotic treatment is important. Higher age of patients, new risk factors, and increasing use of intravascular prosthetic materials resulted in changes in microbial spectrum. Nowadays, nonspecific symptoms, critically ill patients, and immunocompromised patients require a high level of diagnostic expertise.The new guidelines from the European Society of Cardiology provide various diagnostic algorithms and recommendations for antibiotic treatment. The new guidelines also recommend the formation of an endocarditis team with various medical disciplines, including a cardiac surgeon, to improve treatment because in half of all endocarditis patients, antibiotic therapy alone does not result in successful management of the infection. If complications occur, early surgical treatment should be performed.In this overview, diagnostic strategies and therapeutic approaches for the treatment of infectious endocarditis according to the current guidelines and aspects of surgical treatment are provided.

    Central nonfocal neuropsychiatric systemic lupus erythematosus (NPSLE) manifests as cognitive dysfunction, acute confusional state, seizures, and psychosis. Valvular heart disease (VHD) is currently not a causal consideration of nonfocal NPSLE. The objective of this study was to determine whether VHD is associated with nonfocal NPSLE. Twenty-eight patients with SLE underwent: 1) clinical and laboratory evaluations; 2) neuropsychiatric evaluation; 3) brain magnetic resonance imaging (MRI); and 4) transesophageal echocardiography (TEE). Their findings were compared with those of 28 age- and-sex matched healthy volunteers. Eighteen patients (64%) had nonfocal NPSLE. Cerebral infarcts on MRI were more common in patients with than without NPSLE (50% vs 10%, P=0.048) and antiphospholipid antibodies (aPL) were associated with old cerebral infarcts (P=0.03). Valvular heart disease was detected in 20 patients (71%) of whom 20 (71%) had valve thickening, 17 (61%) had valve regurgitation, and 15 (53%) had valve vegetations (12 on the mitral valve). Mitral valve vegetations were more common in patients with than without nonfocal NPSLE and in those with old cerebral infarcts (61% vs 10% and 75% vs 30%, respectively, P=0.02 for both). The nonneurologic activity of SLE and mitral valve vegetations were the only independent predictors of NPSLE (odds ratio [OR], 1.27 per unit value; confidence interval [CI], 1.1-1.6; P=0.03; and OR, 16.5; CI, 1.26-217; P=0.03, respectively). Among controls, none had neuropsychiatric syndromes, 4 (15%) had MRI abnormalities, and 3 (11%) had VHD (all P=0.001 vs patients). Nonfocal NPSLE, cerebral infarcts, and VHD were highly associated and mitral valve vegetations were independent predictors of NPSLE. Thus, VHD exacerbated by hypercoagulability may cause thromboembolic ischemic brain injury and nonfocal NPSLE.

    Burned patients are at high risk for invasive procedures, bacteremia, and other infectious complications. Previous publications describe high incidence, delayed diagnosis, and high mortality for endocarditis in burned patients, but do not address use of contemporary diagnostic criteria. Further analysis of the clinical presentation and diagnosis may aid in the earlier recognition and decreased mortality of endocarditis in burned patients. At a 40 bed burn center, during the period from 1 January 2003 to 1 August 2006, blood culture, electronic inpatient, echocardiographic, and autopsy records were reviewed for cases of endocarditis and persistent bacteremia (blood culture positivity for the same organism separated by 24h). In addition, we reviewed cases of burn-related bacterial endocarditis published in the English language. We compared the clinical and diagnostic aspects of our identified cases with those in the published literature. There were 90 episodes of persistent bacteremia or fungemia in 56 of 1250 patients admitted during the study period. Echocardiography was performed on 19, identifying 4 cases of endocarditis. One additional case of endocarditis was identified post-mortem. Time until echocardiography ranged from 6 to 176 days after onset of bacteremia. Case patient age ranged from 31 to 64 years, and total burn surface area ranged from 34 to 80%. Endocarditis occurred in 0.4% of burn unit admissions and in 8.9% of these patients with persistent bacteremia. Sites involved included the mitral valve (3), tricuspid valve (2), aortic valve (1), and pulmonic valve (1). Pathogens included Staphylococcus aureus, Pseudomonas aeruginosa, and one case of Enterococcus faecium. Diagnostic clues were minimal. Case mortality was 100%. A literature review revealed 17 publications describing confirmed bacterial endocarditis in burned patients. These cases revealed a predilection for infection by S. aureus and P. aeruginosa, a relative paucity of diagnostic clues prior

    Full Text Available Although infective endocarditis (IE has been described in reports dating from the Renaissance, the diagnosis still challenges and the outcome often surprises. In the course of time, diagnostic criteria have been updated and validated to reduce misdiagnosis. Some risk factors and epidemiology have shown dynamic changes since degenerative valvular disease became more predominant in developed countries, and the mean age of the affected population increased. Despite streptococci have been being well known as etiologic agents, some groups, although rare, have been increasingly reported (e.g., Streptococcus milleri. Intracardiac complications of IE are common and have a worse prognosis, frequently requiring surgical treatment. We report a case of a middle-aged diabetic man who presented with prolonged fever, weight loss, and ultimately severe dyspnea. IE was diagnosed based on a new valvular regurgitation murmur, a positive blood culture for Streptococcus anginosus, an echocardiographic finding of an aortic valve vegetation, fever, and pulmonary thromboembolism. Despite an appropriate antibiotic regimen, the patient died. Autopsy findings showed vegetation attached to a bicuspid aortic valve with an associated septal abscess and left ventricle and aortic root fistula connecting with the pulmonary artery. A large thrombus was adherent to the pulmonary artery trunk and a pulmonary septic thromboemboli were also identified.

    Full Text Available Abstract Introduction Acute ST-segment elevation myocardial infarction secondary to atherosclerotic plaque rupture is a common medical emergency. This condition is effectively managed with percutaneous coronary intervention or thrombolysis. We report a rare case of acute myocardial infarction secondary to coronary embolisation of valvular vegetation in a patient with infective endocarditis, and we highlight how the management of this phenomenon may not be the same. Case presentation A 73-year-old British Caucasian man with previous tissue aortic valve replacement was diagnosed with and treated for infective endocarditis of his native mitral valve. His condition deteriorated in hospital and repeat echocardiography revealed migration of vegetation to his aortic valve. Whilst waiting for surgery, our patient developed severe central crushing chest pain with associated anterior ST segment elevation on his electrocardiogram. Our patient had no history or risk factors for ischaemic heart disease. It was likely that coronary embolisation of part of the vegetation had occurred. Thrombolysis or percutaneous coronary intervention treatments were not performed in this setting and a plan was made for urgent surgical intervention. However, our patient deteriorated rapidly and unfortunately died. Conclusion Clinicians need to be aware that atherosclerotic plaque rupture is not the only cause of acute myocardial infarction. In the case of septic vegetation embolisation, case report evidence reveals that adopting the current strategies used in the treatment of myocardial infarction can be dangerous. Thrombolysis risks intra-cerebral hemorrhage from mycotic aneurysm rupture. Percutaneous coronary intervention risks coronary mycotic aneurysm formation, stent infections as well as distal septic embolisation. As yet, there remains no defined treatment modality and we feel all cases should be referred to specialist cardiac centers to consider how best to proceed.

    We report the case of a 43-year-old man admitted for right hip ache and fever. Physical examination revealed a fever, an ache at the manipulation of the sacroiliac joint and a limitation of abduction and external rotation of the right hip. There was no murmur in cardiac auscultation. No anomaly was found at the conventional radiographs of the sacroiliac joint, while the pelvic MRI confirmed a right sacroiliitis. A sacroiliac puncture with a study of synovial fluid demonstrated the presence of Streptococcus viridans. The blood culture revealed the same germ. Transthoracic and transoesophageal echocardiography confirmed infectious endocarditis with vegetation in the mitral valve. He received penicillin G and gentamicin relayed by pristinamycin because of an allergy to penicillin G with a total duration of treatment of 40 days. His symptoms and the laboratory and radiological tests abnormalities resolved totally with no recurrence. PMID:25123569

    The human gingival niche is a unique microbial habitat. In this habitat, biofilm organisms exist in harmony, attached to either enamel or cemental surfaces of the tooth as well as to the crevicular epithelium, subjacent to a rich vascular plexus underneath. Due to this extraordinary anatomical juxtaposition, plaque biofilm bacteria have a ready portal of ingress into the systemic circulation in both health and disease. Yet the frequency, magnitude, and etiology of bacteremias due to oral origin and the consequent end organ infections are not clear and have not recently been evaluated. In this comprehensive review, we address the available literature on triggering events, incidence, and diversity of odontogenic bacteremias. The nature of the infective agents and end organ infections (other than endocarditis) is also described, with an emphasis on the challenge of establishing the link between odontogenic infections and related systemic, focal infections.

    Full Text Available Organisms of the genus Gemella can, on occasion, cause serious systemic illness. The present paper reports a successfully treated case of endocarditis in a 12-year-old girl with congenital heart disease caused by species of Gemella. The child presented with cough, fatigue and decreased appetite without fever. Echocardiogram demonstrated marked mitral insufficiency with flail posterior mitral valve leaflet, mitral valve vegetations, and an enlarged left atrium and ventricle. While being treated with vancomycin, the child initially had persistent bacteremia, which resolved after the addition of gentamycin; the course of therapy was completed with penicillin G and gentamycin once antimicrobial susceptibilities were available. Attempts to identify the species of Gemella were unsuccessful in the local laboratory, and at reference laboratories in Canada and the United States. The isolate is undergoing further evaluation to determine its taxonomic status.

    Although often clinically suspected, infectious endocarditis (IE) is frequently difficult to diagnose with certainty. Although the dermatological signs of endocarditis can vary, they must be routinely sought where there is a suspicion of IE. The aim of this study was to reveal the diversity of clinical manifestations of IE in a dermatology unit. This retrospective study was conducted between May 2006 and May 2007 and included all patients hospitalized in the dermatology unit in whom an IE was diagnosed according to the modified Duke criteria. Seven patients were included with a median age of 61 years. The reasons for hospital admission were: chronic ulcers (n=1), Sezary's syndrome (n=1), atopic dermatitis (n=1), epidermolysis bullosa acquisita (n=1) and purpura (n=1). Specific dermatological manifestations of IE included necrotic lesions on the lower limbs (n=2), purpura (n=5) and splinter haemorrhages (n=1). Blood cultures were positive in 3 cases (MSSA=2, MRSA=1). One patient had serological evidence of Coxiella burnetti IE. Cutaneous sources of IE were found in 6 cases, including acute dermohypodermitis or chronic dermatosis (3), peripheral venous catheter (n=2) and haemodialysis (n=1). Transthoracic echocardiography was negative in 6 patients, whereas transoesophageal echocardiography performed in 6 patients confirmed the diagnosis in 5 cases. The mean time to diagnosis was 21 days. Among these patients, 5 died after a mean period of 78 days. Diagnosing IE remains a clinical challenge and must be routinely considered in the presence of unusual dermatological findings such as purpura or distal necrosis, but also in patients with partially or poorly controlled chronic dermatosis, which comprise an underestimated potential source of IE. Physicians treating such patients must consider the risk of IE, especially in the event of chronic dermatosis or of an invasive cutaneous procedure involving affected skin.

    In this chapter, we review the working hypothesis that the roots of adult valvular heart disease (VHD) lie in embryonic development. Valvulogenesis is a complex process in which growth factors signal the process of endocardium-to-mesenchyme transformation (EMT) resulting in formation of prevalvular "cushions." The post-EMT processes, whereby cushions are morphogenetically remolded into valve leaflets, are less well understood, but they require periostin. Mice with targeted deletion of periostin develop degenerative changes similar to human forms of VHD. Mitral valves are also abnormally elongated in hypertrophic cardiomyopathy (HCM), which plays an important role in clinical disease expression. However, the mechanism for this is unclear, but correlates with enhanced expression of periostin in a specific population of ventricular cells derived from the embryonic proepicardial organ, which accumulate at sites where valvular endocardial EMT is reactivated. Collectively, these findings suggest that developmental mechanisms underlie adult valve responses to genetic mutations in degenerative VHD and HCM.

    We report a case of biopsy-proven secondary hemosiderosis of the lung in a 58-year-old patient with mitral valvular heart disease. Both chest radiography and high-resolution CT demonstrated patchy areas of ground-glass opacity ; the former indicated that it was in both lungs, while the latter showed inter-and intralobular septal thickening. These findings were reversible when pulmonary venous hypertension was corrected.

    Few data exist on the outcomes of valvular cardiomyopathy patients referred for defibrillator implantation for primary prevention. The aim of the present study was to describe the outcomes of this cardiomyopathy subgroup. This multicenter retrospective study included consecutive patients referred for defibrillator implantation to 15 Spanish centers in 2010 and 2011, and to 3 centers after 1 January 2008. Of 1174 patients, 73 (6.2%) had valvular cardiomyopathy. These patients had worse functional class, wider QRS, and a history of atrial fibrillation vs patients with ischemic (n=659; 56.1%) or dilated (n=442; 37.6%) cardiomyopathy. During a follow-up of 38.1 ± 21.3 months, 197 patients (16.7%) died, without significant differences among the groups (19.2% in the valvular cardiomyopathy group, 15.8% in the ischemic cardiomyopathy group, and 17.9% in the dilated cardiomyopathy group; P=.2); 136 died of cardiovascular causes (11.6%), without significant differences among the groups (12.3%, 10.5%, and 13.1%, respectively; P=.1). Although there were no differences in the proportion of appropriate defibrillator interventions (13.7%, 17.9%, and 18.8%; P=.4), there was a difference in inappropriate interventions (8.2%, 7.1%, and 12.0%, respectively; P=.03). All-cause and cardiovascular mortality in patients with valvular cardiomyopathy were similar to those in other patients referred for defibrillator implantation. They also had similar rates of appropriate interventions. These data suggest that defibrillator implantation in this patient group confers a similar benefit to that obtained by patients with ischemic or dilated cardiomyopathy.

    For AS, besides a very thorough update by Carabello on their management, new experimental work confirms that the pathophysiology of the condition is closer to atherosclerotic and inflammatory processes than pure degeneration. Moreover this year brings a batch of long term post-operative results, one of which is an important series relating to 2194 bioprostheses followed up for 15 years. The choice of valvular substitute between 60 and 70 years old is the subject for several studies. A series of 259 re-operations for bioprosthesis deterioration allows quantification of the operative risk to which those with this substitute are subjected in case of degeneration. Finally, the strategy to adopt in a patient with an indication for aortocoronary bypass but also with a not-tight AS is discussed (abstention, decalcification, or "preventive" valvular replacement?). For aortic insufficiency (AI) some new results for the Ross operation have been published and the first publications reporting on the attempts of experimental positioning of bioprostheses via the percutaneous route in animals are appearing. As for mitral valvulopathies, MI has carved a privileged place. Much work this year relates amongst other things to functional MI in dilated cardiomyopathies with dilatation of the ring, to the natural history of mitral valvular prolapse detailed in an important series of 833 patients, and to the evolutive risk of atrial fibrillation (AF) with MI and its treatment during plasty or mitral valvular replacement procedures. Anticoagulant treatment for mechanical prostheses is the subject of much work drawn from a large German prospective study (GELIA) confirming the general tendency for alleviation of intensity in aortic especially but also mitral valvulopathies, stressing the advantages of autocontrol. Finally, the Valvulopathy Working Group of the European Society of Cardiology publishes its recommendations for asymptomatic valvulopathies, recalling the echographic criteria of

Estudios recientes reportan mejores resultados, a corto y largo plazo, posteriores al procedimiento.   OBJETIVO: analizar la experiencia del reemplazo valvular mitral en el Instituto Nacional de Pediatría.   MATERIALES Y MÉTODOS: se revisaron los expedientes de los pacientes con reemplazo valvular mitral, en el Instituto Nacional de Pediatría, entre agosto del 2002 y agosto del 2012. Las variables de evaluación primaria fueron mortalidad, complicaciones de la anticoagulación y resultados a largo plazo. Se incluyó a doce pacientes, con mediana de edad de 12.5 años (tres pacientes menores de 5 años. RESULTADOS: en 11 casos la anomalía mitral fue considerada congénita. La manifestación clínica más frecuente fue insuficiencia mitral. La mediana de la fracción de eyección del ventrículo izquierdo fue de 62% antes de la cirugía. Se colocó prótesis mecánica en 11 casos. Dos pacientes fallecieron en el postoperatorio inmediato, con supervivencia a 30 días de 83%, sin reporte de ninguna muerte en el periodo de seguimiento. Un paciente presentó sangrado de  tubo digestivo leve y dos arritmia auricular. No se reportaron eventos tromboembólicos ni necesidad de nueva intervención. La mediana del tiempo de seguimiento fue de 16.6 meses.   CONCLUSIÓN: en nuestras condiciones el reemplazo valvular mitral parece ser una buena opción para los pacientes que no pueden beneficiarse de la reparación, con resultados aceptables a corto y mediano plazos.

  10. Newer Anticoagulants for Non-Valvular Atrial Fibrillation

    Directory of Open Access Journals (Sweden)

    Joseph M. Harburger

    2012-05-01

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

    When magnetic resonance phase mapping is used to quantitate valvular blood flow, the presence of higher-order-motion terms may cause a loss of phase information. To overcome this problem, a sequence with reduced encoding for higher-order motion was used, achieved by decreasing the duration of the...... mapping is also valid for pathologic conditions. Phase mapping may be used as a noninvasive clinical tool for flow quantification in heart valve disease....... of the flow-encoding gradient to 2.2 msec. Tested on a flow phantom simulating a severe valvular stenosis, the sequence was found to be robust for higher-order motion within the clinical velocity range. In eight healthy volunteers, mitral and aortic volume flow rates and peak velocities were quantified...... by means of phase mapping and compared with results of the indicator-dilution technique and Doppler echocardiography, respectively. Statistically significant correlations were found between phase mapping and the other two techniques. Similar studies in patients with valvular disease indicate that phase...

    2017-01-01

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

    We performed combined operation for patients who have both ischemic heart disease and valvular heart disease in 21 cases from January 1991 to October 1999. This operation was 3.1% of 682 cases of coronary artery bypass grafting and 5.0% of 416 cases of operation for valvular heart disease during that period. The mean age of these patients was 67.9 +/- 9.1 years. The average number of grafts in the coronary artery bypass grafting was 1.5 +/- 0.6. Aortic valve replacement was performed in 6 cases, mitral valve replacement in 10 cases and mitral valve plasty in 5 cases. Together with this combined operation, ascending aorta and aortic arch replacement was done in 1 case and abdominal aortic replacement in 2 cases. Three patients died due to postoperative aortic rupture, cerebral infarction or excessive surgical intervention in ascending aorta and aortic arch replacement. Combined operation for ischemic heart diseases and valvular heart diseases can safely performed, but it appears necessary to pay attention to arteriosclerotic lesions.

    We describe the first reported case of acute methemoglobinemia associated with ochronotic valvular heart disease. A 79-year-old man with ochronotic valvular heart disease experienced decreased urinary output starting 9 days after an operation. Thereafter, the patient's methemoglobin concentration acutely increased, indicating systemic cyanosis, while the arterial partial oxygen pressure (PaO (2)) was maintained at around 200 mmHg. In patients with ochronotic valvular heart disease, acute methemoglobinemia may occur, as in cases of renal failure or oliguresis.

    2016-01-01

    Background: Although atrial fibrillation (AF), a common arrhythmia, frequently presents in patients with underlying valvular disease, its hemodynamic contributions are not fully understood. The present work aimed to computationally study how physical conditions imposed by pathologic valvular anatomy act on AF hemodynamics. Methods: We simulated AF with different severity grades of left-sided valvular diseases and compared the cardiovascular effects that they exert during AF, compared to lone ...

  17. Ecto-5'-nucleotidase: a candidate virulence factor in Streptococcus sanguinis experimental endocarditis.

    Full Text Available Streptococcus sanguinis is the most common cause of infective endocarditis (IE. Since the molecular basis of virulence of this oral commensal bacterium remains unclear, we searched the genome of S. sanguinis for previously unidentified virulence factors. We identified a cell surface ecto-5'-nucleotidase (Nt5e, as a candidate virulence factor. By colorimetric phosphate assay, we showed that S. sanguinis Nt5e can hydrolyze extracellular adenosine triphosphate to generate adenosine. Moreover, a nt5e deletion mutant showed significantly shorter lag time (P<0.05 to onset of platelet aggregation than the wild-type strain, without affecting platelet-bacterial adhesion in vitro (P=0.98. In the absence of nt5e, S. sanguinis caused IE (4 d in a rabbit model with significantly decreased mass of vegetations (P<0.01 and recovered bacterial loads (log(10CFU, P=0.01, suggesting that Nt5e contributes to the virulence of S. sanguinis in vivo. As a virulence factor, Nt5e may function by (i hydrolyzing ATP, a pro-inflammatory molecule, and generating adenosine, an immunosuppressive molecule to inhibit phagocytic monocytes/macrophages associated with valvular vegetations. (ii Nt5e-mediated inhibition of platelet aggregation could also delay presentation of platelet microbicidal proteins to infecting bacteria on heart valves. Both plausible Nt5e-dependent mechanisms would promote survival of infecting S. sanguinis. In conclusion, we now show for the first time that streptococcal Nt5e modulates S. sanguinis-induced platelet aggregation and may contribute to the virulence of streptococci in experimental IE.

  18. Avoiding transthoracic echocardiography and transesophageal echocardiography for patients with variable body mass indexes in infective endocarditis

    2016-04-01

    Full Text Available Background: Echocardiography has been a popular modality used to aid in the diagnosis of infective endocarditis (IE with the modified Duke criteria. We evaluated the necessity between the uses of either a transthoracic echocardiography (TTE or transesophageal echocardiography (TEE in patients with a body mass index (BMI greater than or equal to 25 kg/m2 and less than 25 kg/m2. Methods: A single-centered, retrospective study of 198 patients between 2005 and 2012 diagnosed with IE based on modified Duke criteria. Patients, required to be above age 18, had undergone an echocardiogram study and had blood cultures to be included in the study. Results: Among 198 patients, two echocardiographic groups were evaluated as 158 patients obtained a TTE, 143 obtained a TEE, and 103 overlapped with TEE and TTE. Out of these patients, 167 patients were included in the study as 109 (65% were discovered to have native valve vegetations on TEE and 58 (35% with TTE. TTE findings were compared with TEE results for true negatives and positives to isolate valvular vegetations. Overall sensitivity of TTE was calculated to be 67% with a specificity of 93%. Patients were further divided into two groups with the first group having a BMI ≥25 kg/m2 and the subsequent group with a BMI <25 kg/m2. Patients with a BMI ≥25 kg/m2 who underwent a TTE study had a sensitivity and specificity of 54 and 92%, respectively. On the contrary, patients with a BMI < 25 kg/m2 had a TTE sensitivity and specificity of 78 and 95%, respectively. Conclusions: Patients with a BMI <25 kg/m2 and a negative TTE should refrain from further diagnostic studies, with TEE strong clinical judgment is warranted. Patients with a BMI ≥ 25 kg/m2 may proceed directly to TEE as the initial study, possibly avoiding an additional study with a TTE.

    2016-07-01

    Full Text Available miRNAs are a class of over 5000 noncoding RNAs that regulate more than half of the protein-encoding genes by provoking their degradation or preventing their translation. miRNAs are key regulators of complex biological processes underlying several cardiovascular disorders, including left ventricular hypertrophy, ischemic heart disease, heart failure, hypertension and arrhythmias. Moreover, circulating miRNAs herald promise as biomarkers in acute myocardial infarction and heart failure. In this context, this review gives an overview of studies that suggest that miRNAs could also play a role in valvular heart diseases. This area of research is still at its infancy, and further investigations in large patient cohorts and cellular or animal models are needed to provide strong data. Most studies focused on aortic stenosis, one of the most common valvular diseases in developed countries. Profiling and functional analyses indicate that miRNAs could contribute to activation of aortic valve interstitial cells to a myofibroblast phenotype, leading to valvular fibrosis and calcification, and to pressure overload-induced myocardial remodeling and hypertrophy. Data also indicate that specific miRNA signatures, in combination with clinical and functional imaging parameters, could represent useful biomarkers of disease progression or recovery after aortic valve replacement.

    Sensitivity and specificity of the modified Duke criteria for native valve endocarditis are both suboptimal, at approximately 80%. Diagnostic accuracy for intracardiac prosthetic material-related infection is even lower. Non-invasive imaging modalities could potentially improve diagnosis of infective endocarditis; however, their diagnostic value is unclear. We did a systematic literature review to critically appraise the evidence for the diagnostic performance of these imaging modalities, according to PRISMA and GRADE criteria. We searched PubMed, Embase, and Cochrane databases. 31 studies were included that presented original data on the performance of electrocardiogram (ECG)-gated multidetector CT angiography (MDCTA), ECG-gated MRI, 18 F-fluorodeoxyglucose ( 18 F-FDG) PET/CT, and leucocyte scintigraphy in diagnosis of native valve endocarditis, intracardiac prosthetic material-related infection, and extracardiac foci in adults. We consistently found positive albeit weak evidence for the diagnostic benefit of 18 F-FDG PET/CT and MDCTA. We conclude that additional imaging techniques should be considered if infective endocarditis is suspected. We propose an evidence-based diagnostic work-up for infective endocarditis including these non-invasive techniques. Copyright © 2017 Elsevier Ltd. All rights reserved.

  7. Isolated pulmonic valve endocarditis presenting as neck pain

    2015-12-01

    Full Text Available We discuss a unique case of a 52-year-old man with no history of intravenous drug use or dental procedures who presented with neck pain, 2 weeks of fevers, chills, night sweats, cough, and dyspnea found to have isolated pulmonic valve (PV endocarditis. The patient did not have an associated murmur, which is commonly seen in right-sided infectious endocarditis. A transthoracic echocardiogram showed a thickened PV leaflet, with subsequent transesophageal echocardiogram showing a PV mass. Speciation of blood cultures revealed Streptococcus oralis. In right-sided infective endocarditis, usually the tricuspid valve is involved; however, in our case the tricuspid valve was free of any mass or vegetation. The patient did meet Duke criteria and was thus started on long-term intravenous antibiotics for infectious endocarditis. The patient's symptoms quickly improved with antibiotics. A careful history and evaluating the patient's risk factors are key in earlier detection of infective endocarditis (IE. Because of early detection and a high index of suspicion, the patient had no further complications and did not require any surgery. In conclusion, clinical suspicion of right-sided IE should be high in patients who present with persistent fevers and pulmonary symptoms in order to reduce the risk of complications, and to improve outcomes.

    We investigated the role of granulocytes during the induction and course of experimental Streptococcus sanguis endocarditis in rabbits by depleting blood granulocytes with nitrogen mustard. The induction of the endocarditis was not influenced by granulocytopenia: the 50% infectious dose was 5.4 X 10(4) colony-forming units in normal and granulocytopenic rabbits. However, granulocytopenia influenced the curse of the endocarditis, as shown by a significant increase in the number of colony-forming units per gram of vegetation (P less than 0.02) from 24 to 72 h after the injection of 10(5) colony-forming units of S. sanguis. This rise did not occur in the control rabbits. Furthermore, bacteremia was significantly higher in the granulocytopenic rabbits (P less than 0.05) during the first 48 h compared with the control rabbits. This was not because of altered clearance of the streptococcus inoculum or seeding of streptococci from extracardiac bacterial foci. We concluded that granulocytes have no measurable effect on the induction of S. sanguis endocarditis, but during the course of the endocarditis, granulocytes keep the endocardial infection in check.

    Full Text Available La cabergolina y la bromocriptina son fármacos agonistas dopaminérgicos utilizados para tratar la hiperprolactinemia, así como la enfermedad de Parkinson. Entre sus efectos adversos considerados como "muy raros" se ha descrito la capacidad de inducir cambios fibróticos en el aparato valvular cardiaco, inicialmente descritos en pacientes con enfermedad de Parkinson, en quienes se emplean dosis superiores a las que de manera habitual se emplean en el tratamiento de la hiperprolactinemia. Varios estudios han señalado la evidencia de estos hechos y de los posibles mecanismos por los cuales la afectación valvular ocurre. Existen hasta el momento pocas investigaciones sobre el asunto en pacientes con hiperprolactinemia, pero la mayoría de ellos indican que su empleo en este tipo de pacientes no produce afectación valvular clínicamente relevante, hecho que pudiera estar en relación con las dosis empleadas (como promedio 10 veces inferiores a las usadas en la enfermedad de Parkinson; sin embargo, se han detectado algunas anomalías subclínicas en el aparato valvular. Dado lo novedoso del tema y la poca evidencia de estos hechos en pacientes tratadas por hiperprolactinemia se ofreció una amplia revisión sobre el tema.Cabergoline and bromocriptine are dopaminergic agonists drugs used in hyperprolactinemia treatment, as well as in patients with Parkinson's disease. Among its adverse effects considered as "very inusual" is included the ability to induce fibrotic changes in cardiac valvular tract first described in patients with Parkinson disease using doses higher than those usually used in hyperprolactinemia treatment. Some studies have mentioned the evidence on these facts and of the possible mechanisms causing the valvular affection. Until now, there are not much researches on this subject in patients with hyperprolactinemia, but most indicated that its use in this kind of patient can not to produce a clinically relevant valvular afection

    Full Text Available Abstract Introduction Stenotrophomonas maltophilia is an environmental bacterium increasingly involved in nosocomial infections and resistant to most antibiotics. It is important to recognize and efficiently treat infections with this bacterium as soon as possible. Case presentation We present a case of Stenotrophomonas maltophilia prosthetic valve endocarditis secondary to an indwelling catheter infection. The patient was cured without surgery. We review other cases of S. maltophilia endocarditis from the literature and describe the peculiarities of this case. Conclusion S. maltophilia endocarditis is a rare disease that is often hospital-acquired and related to an indwelling catheter infection. The high lethality is likely related to the intrinsic resistance of nosocomial bloodstream infections to commonly prescribed antibiotics.

    Mitral valve aneurysms are rare complications occurring most commonly in association with aortic valve infective endocarditis. [Decroly 1989, Chua 1990, Northridge 1991, Karalis 1992, Roguin 1996, Mollod 1997, Vilacosta 1997, Cai 1999, Vilacosta 1999, Teskey 1999, Chan 2000, Goh 2000, Marcos- Alberca 2000] While the mechanism of the development of this lesion is unclear, complications such as perforation can occur and lead to significant mitral regurgitation. [Decroly 1989, Karalis 1992, Teskey 1999, Vilacosta 1999]; The case of a 69-year-old male with Streptococcus Sanguis aortic valve endocarditis and associated anterior mitral leaflet aneurysm is presented. Following surgery, tissue pathology of the excised lesion revealed myxomatous degeneration and no active endocarditis or inflammatory cells. This may add support to the hypothesis that physical stress due to severe aortic insufficiency and structural weakening, without infection of the anterior mitral leaflet, can lead to the development of this lesion.

    We wanted to assess the quality of antibiotic therapy prescribed for infective endocarditis in our ward. We conducted a retrospective audit of all adult patients with endocarditis hospitalized over a 3-year period in the Infectious Diseases Unit of the Nice University Hospital, France. The quality of antibiotic therapy was assessed using the 2004 European Society of Cardiology guidelines as a reference. Antibiotic therapy was considered as appropriate only if the five following items complied with guidelines: antibiotic, dose, route, interval of administration, and duration of antibiotic treatment. Sixty-six patients were included, 63years of age on average. Antibiotic therapy complied with guidelines in 14% of the cases. The most frequent causes of inappropriate therapy were: gentamicin prescribed as a single daily dose in 55% (27/49) of the cases, unnecessary prescriptions of rifampin in 72% (18/25) of the cases, and too long duration of gentamicin course for staphylococcal endocarditis in 32% (9/28) of the cases. Antibiotic therapy was switched from intravenous to oral route in 29% of the patients (n=19), 18±9 days after starting therapy on average. These endocarditis were mainly left-sided (n=12) and/or complicated (n=15). There was no significant association between mortality and inappropriate antibiotic therapy (14% if inappropriate vs. 22%, P=0.62) or between mortality and oral switch (0% if oral switch vs. 21%, P=0.052). Infective endocarditis antibiotic treatment rarely complied with the 2004 European guidelines, but this did not have a negative impact on mortality. Switching antibiotic therapy from intravenous to oral route was common, even for complicated left-sided endocarditis, and was associated with a favorable outcome in all cases.

    Full Text Available Systemic lupus erythematosus is a chronic systemic autoimmune disease, often associated with severe infection. A female patient was referred for surgical treatment of infective endocarditis after being treated for systemic lupus erythematosus and lupus nephritis. She developed symptoms of left axillary artery occlusion before heart operation. Bulky fungal hyphae were noted on pathological examination of the surgically removed thrombi. The patient had an uncomplicated recovery after receiving high doses of antibiotics and subsequent mitral valve replacement. Either infective endocarditis or fungal thrombi may be secondary to systemic lupus erythematosus and impaired renal function.

    Half of patients with infectious endocarditis have surgery during the active phase of infective endocarditis (before the end of antibiotic therapy). The American Heart Association and the European Society of Cardiology, independently from each other, have published guidelines in September 2015. As regards surgical indications, these guidelines are similar. The surgical indication must be a common decision of a multidisciplinary team of experts in cardiology, cardiac surgery, imaging and infectious diseases. The main indications are heart failure, non-infectious process control and prevention of embolisms. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Infective endocarditis complicated by abscess formation and coronary artery compression is a rare clinical event with a high mortality rate, and diagnosis requires a heightened degree of suspicion. We present the clinical, angiographic, and echocardiographic features of a 73-year-old woman who presented with dyspnea and was found to have right coronary artery compression that was secondary to abscess formation resulting from diffuse infectious endocarditis. We discuss the patient's case and briefly review the relevant medical literature. To our knowledge, this is the first reported case of abscess formation involving a native aortic valve and the right coronary artery.

    We performed an open study to compare efficacy and renal toxicity of cephotaxime versus the usual beta lactam plus aminoglucoside treatment of infectious endocarditis. Twenty cases were studied, 10 treated with cephotaxime 4 g/day per 21 days and aminoglucoside for only 10 days. Comparison group received a combination of different beta lactam antibiotic plus aminoglucoside for 21 to 50 days, these patients were under care of nonparticipant physicians. Although cephotaxime treatment was as good as conventional antimicrobial scheme for control of infectious endocarditis, the treatment cost increases, and there is only marginal benefit in regard renal toxicity.

    Full Text Available Infective endocarditis is a life-threatening disease caused by a focus of infection within the heart. For clinicians and scientists, it has been a moving target that has an evolving microbiology and a changing patient demographic. In the absence of an extensive evidence base to guide clinical practice, controversies abound. Here, we review three main areas of uncertainty: first, in prevention of infective endocarditis, including the role of antibiotic prophylaxis and strategies to reduce health care-associated bacteraemia; second, in diagnosis, specifically the use of multimodality imaging; third, we discuss the optimal timing of surgical intervention and the challenges posed by increasing rates of cardiac device infection.

    Seventy patients with rheumatic valvular disease were evaluated with preoperative CT scanning. The correlation of the obtained CT images to the operative findings were examined. Left atrial thrombi were found in 24 cases at the operation. CT scan had detected thrombi in 19 cases (79.2%) and echocardiography in 15 (62.5%). CT failed to find them in 5 cases in which the left atrial thrombi were less than 3 g. Echocardiogram, however, failed to detect thrombi in 9 cases, the largest being 14 g. There were 15 cases with left atrial calcification, in which 10 cases had left atrial thrombi. Nine cases out of these 10 cases had rough left atrial surface after thrombectomy. Early postoperative CT of 10 with left atrial calcification showed recurrent left atrial thrombi in 4 (40%) cases. Mitral valve calcification was found in 42 cases during operation. CT scan was able to detect it in 40 (95.2%), while echocardiogram detected in 34 cases (81.0%) (p<0.05). All mitral valves with calcification required replacement. Out of 30 cases with non calcified mitral valves, 9 underwent OMC, and the other 21 underwent mitral valve replacement. Aortic valve calcification was found in 9 out of 11 cases of aortic stenosis. All has been diagnosed by CT scan. In conclusion, 1. in detecting the left atrial thrombi, CT scan was superior to echo-cardiography, and provided useful information for planning the operative procedure including atrial approach and valvular manipulation, 2. CT scan could detect calcification of left atrial wall which had high incidence of thrombus formation and rough left atrial surface, 3. CT scan could detect calcification of both mitral and aortic valve, and showed the severity of valvular structural changes. (author).

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

    The aim of the study was to determine factors of risk and progress of aortal valvular calcinosis (AVC) and aortic ostium stenosis (AOS). The subjects were 85 patients with AVC (42--with aortic valvular stenosis (AVS), and 43--without AOS). The study, which included analysis of the lipid and mineral metabolism, and immunological tests, shows that potential factors of AVC are: age (p dislipidemia (high serum level of total cholesterol, cholesterol of low density lipoproteins, and apoB, atherogenic shift of apoB/apoA-1 ratio, low level of cholesterol of high density lipoproteins (CHDLP)), disbalance between intecellular matrix synthesis and destruction (high concentration of alkaline phosphatase and its bone fraction, and accelerated deoxypyridinoline excretion), inflammation (high concentration of C-reactive protein (CRP), fibrinogen, and interleukin-6 (IL-6)). The factors of AOS were: age (p dislipidemia (high levels of cholesterol of low density and very low density lipoproteins, low concentrations of CHDLP, and apoA-1), degradation of extracellular matrix, and inflammation (high concentrations of CRP, fibrinogen, IL-6, and IL-8). Thus, atherogenic dislipidemia and mineral dysmetabolism disorder facilitate AVC. The revealed immune status changes imply the role of inflammation in the development and progress of AVS.

    A retrospective study on 223 patients diagnosed with degenerative heart valvular lesions: 124 women with an average of 74.9 years old and 99 men with an average of 70.1 years old with the lower limit under 50 years old (one woman and one man) and upper limit over 80 years old (22 women and 11 men) revealed that 109 patients (48.8%) had arterial hypertension, 30 patients (13.4%) had diabetes mellitus, and 16 patients (7%) had obesity. Chronic alcoholism was present at 89 patients (39.9%), chronic tobacco consumption at 54 patients (24.2%), cholesterol value over 200mg/dl in 99 patients (44%) and triglycerides value over 150 mg/dl in 15 patients (6.6%). In the 15 patients with a sever form of aortic stenosis was discovered cholesterol value over 200 mg/dl as well as chronic tobacco use and alcoholism. Degenerative heart valvular disease represents a different process from arteriosclerosis, therefore the conventional risk factors of arteriosclerosis, can not be considered as having the same significance for degenerative heart diseases.

  11. The surgical approach to infective endocarditis: 10 year experience.

    About 40% of patients with infective endocarditis will require surgical treatment. The guidelines for such treatment were formulated by the American College of Cardiology and American Heart Association in 1998. To examine our experience with surgical treatment of infective endocarditis in light of these guidelines. Surgery was performed in 59 patients with infective endocarditis between 1990 and 1999. The patients' mean age was 48 years (range 13-80). The indications for surgery were hemodynamic instability, uncontrolled infection, and peripheral embolic events. The surgical treatment was based on elimination of infection foci and correction of the hemodynamic derangement. These objectives were met with valve replacement in the majority of patients. Whenever conservative surgery was possible, resection of vegetation and subsequent valve repair were performed and the native valve was preserved. Six patients (10%) died perioperatively from overwhelming sepsis (n = 3), low cardiac output (n = 2) and multiogran failure (n = 1). The mean hospital stay was 15.6 days. Of 59 patients, 47 (80%) underwent valve replacement and in 11 (19%) the surgical treatment was based on valve repair. After 1 year of follow-up there was no re-infection. The new guidelines for surgical treatment of infective endocarditis allow better selection of patients and timing of surgery for this aggressive disease, which consequently decreases the mortality rate. Valve repair is feasible and is preferred whenever possible. According to the new guidelines, patients with neurologic deficit in our series would not have been operated upon, potentially decreasing the operative mortality to 7%.

    Full Text Available The clinical presentation of infective endocarditis varies according to theetiologic agent and the host. In elderly individuals, infective endocarditis canbe difficult to diagnose and poses a challenge for the physician. The course ofsubacute infective endocarditis is indolent, and the onset of cardiac structurallesion is slow and gradual. In elderly patients, anemia and weight loss areoccasionally the only or the most striking symptoms. In such cases, the clinicalreasoning process leads to a hypothesis of wasting syndrome or neoplasticdisease, especially when there is no fever. We report the case of an elderlypatient who had mitral insufficiency due to degenerative valve disease andpresented with bacterial endocarditis due to Streptococcus mitis. The patientwas not treated, because the diagnosis was not established in a timely manner.It is of note that the patient presented with marked weight loss and no fever.The autopsy revealed impairment of the mitral valve and left atrium due toendocarditis, as well as lung involvement due to chronic inhalation of smokefrom biomass burning, such as that produced by wood-burning stoves.

    Full Text Available In humans, one of the major factors associated with infective endocarditis (IE is the concurrent presence of periodontal disease (PD. However, in veterinary medicine, the relevance of PD in the evolution of dogs' endocarditis remains poorly understood. In order to try to establish a correlation between mouth-associated Enterococcus spp. and infective endocarditis in dogs, the present study evaluated the presence and diversity of enterococci in the gum and heart of dogs with PD. Samples were collected during necropsy of 32 dogs with PD and visually diagnosed with IE, which died of natural causes or euthanasia. Enterococci were isolated, identified and further characterized by Pulsed-Field Gel Electrophoresis (PFGE; susceptibility to antimicrobial agents and pathogenicity potential was also evaluated. In seven sampled animals, PFGE-patterns, resistance and virulence profiles were found to be identical between mouth and heart enterococci obtained from the same dog, allowing the establishment of an association between enterococcal periodontal disease and endocarditis in dogs. These findings represent a crucial step towards understanding the pathogenesis of PD-driven IE, and constitute a major progress in veterinary medicine.

    Dentigenous, infectious foci are frequently associated with the development of various diseases. The role of such foci in the evolution of endocarditis still remains unclear. This article presents the concluding results of an interdisciplinary study verifying the influence of dentigenous, infectious foci on the development of infective endocarditis. The study subjects were 60 adult patients with history of infective endocarditis and coexistent acquired heart disease, along with the presence at least 2 odontogenic infectious foci (ie, 2 or more teeth with gangrenous pulp and periodontitis). The group had earlier been qualified for the procedure of heart valve replacement. Swabs of removed heart valve tissue with inflammatory lesions and blood were then examined microbiologically. Swabs of root canals and their periapical areas, of periodontal pockets, and of heart valves were also collected. Microbial flora, cultured from intradental foci, blood and heart valves, fully corresponded in 14 patients. This was accompanied in almost all cases by more advanced periodontitis (2nd degree, Scandinavian classification), irrespective of the bacterial co-occurrence mentioned. In the remaining patients, such consistency was not found. Among various dentigenous, infectious foci, the intradental foci appear to constitute a risk factor for infective endocarditis.

    Full Text Available We report the first case of native and recurrent prosthetic valve endocarditis with Corynebacterium CDC group G, a rarely reported cause of infective endocarditis (IE. Previously, there have been only two cases reported for prosthetic valve IE caused by these organisms. A 69-year-old female with a known history of mitral valve regurgitation presented with a 3-day history of high-grade fever, pleuritic chest pain and cough. Echocardiography confirmed findings of mitral valve thickening consistent with endocarditis, which subsequently progressed to become large and mobile vegetations. Both sets of blood cultures taken on admission were positive for Corynebacterium CDC group G. Despite removal of a long-term venous access port, the patient’s presumed source of line associated bacteremia, mitral valve replacement, and aggressive antibiotic therapy, the patient had recurrence of vegetations on the prosthetic valve. She underwent replacement of her prosthetic mitral valve in the subsequent 2 weeks, before she progressed to disseminated intravascular coagulation and expired. Although they are typically considered contaminants, corynebacteria, in the appropriate clinical setting, should be recognized, identified, and treated as potentially life-threatening infections, particularly in the case of line-associated bacteremias, and native and prosthetic valve endocarditis.

    Full Text Available La granulomatosis de Wegener es una vasculitis necrotizante autoinmune cuya prevalencia reportada es de 3/100.000 habitantes. Tiene compromiso multisistémico, principalmente el tracto respiratorio superior e inferior, y el sistema nervioso central y renal. La frecuencia del compromiso cardiaco varía según las series estudiadas, pero oscila alrededor de 6%; sin embargo, las manifestaciones clínicas son poco frecuentes. El compromiso valvular se reporta como insuficiencia aórtica o mitral, secundaria a infiltración de las valvas o dilatación de la raíz aórtica. El tratamiento se basa en el control de la enfermedad, el manejo de la falla cardiaca y la intervención quirúrgica de la válvula comprometida según la indicación.Wegener's granulomatosis is an autoimmune necrotizing vasculitis with a reported prevalence of 3/100.000 inhabitants. It is a multisystemic disease, involving mainly the upper and lower respiratory tract, the central nervous system and the kidneys. The frequency of cardiac involvement varies depending on the series studied, but oscillates around 6%; however, the clinical manifestations are rare. The valvular involvement is reported as aortic or mitral insufficiency secondary to infiltration of the leaflets, or as aortic root dilatation. Treatment is based on the control of the disease, the management of heart failure and surgical intervention of the involved valve, as directed.

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

    A patient with late prosthetic endocarditis resulting from Moraxella non-liquefaciens is reported. Correct laboratory indentification is of therapeutic importance as Moraxella is often highly sensitive to penicillin. Because of suspected penicillin sensitivity, antibiotics other than penicillin were used, but failed to control the endocarditis. Prompt response occurred when penicillin was given. Penicillin remains by far the most effective antibiotic for the treatment of endocarditis, particu...

    HACEK endocarditis is often difficult to diagnose given the slow-growing characteristics of the organisms involved. Haemophilus parainfluenzae, one of the HACEK organisms, is an uncommon cause of endocarditis. We describe a case of a previously healthy young man with H parainfluenzae endocarditis that was associated with maxillary sinusitis and severe systemic complications, including septic cerebral emboli and mitral valve perforation. Previously reported cases have also described a predilection for younger people, cardiac valve pathology, and a high prevalence of stroke.

  7. Stress Doppler echocardiography in valvular heart diseases: utility and assessment.

    Science.gov (United States)

    O'Connor, Kim; Lancellotti, Patrizio; Piérard, Luc A

    2010-09-01

    This article is a review on the role of stress echocardiography in valvular heart diseases, describing what the validated indications are, how to perform the test and the utility of performing this examination. Most valve diseases are characteristically dynamic and this dynamic component is best appreciated by exercise Doppler echocardiography. Dobutamine stress echocardiography is also useful in patients with severe aortic stenosis and left ventricular dysfunction. The main advantage of stress echocardiography is to concomitantly allow the evaluation of symptoms, exercise capacity and the hemodynamic consequences of valve diseases, especially in patients with severe valve diseases who deny symptoms or present equivocal symptoms. It also provides important prognostic information and may help to optimize surgical timing in difficult cases. Whether these data should be integrated in the management of patients needs further validation.

    1996-08-01

    Between July 1994 and August 1995, 14 patients underwent combined modified maze procedure and valvular surgery including 5 patients having reoperation. Associated procedures were performed with mitral valve operation (n = 13), tricuspid annuloplasty or valve replacement (n = 9) and aortic valve replacement (n = 4). Duration of atrial fibrillation (AF) varied from 1 to 18 years (mean 8.0 +/- 5.8 year), the f-wave voltage ranged from 0.05 to 0.5 mV (0.21 +/- 0.13 mV), left atrial dimension (LAD) ranged from 35.6 to 66.3 mm (49.0 +/- 9.3). One patient died 2 months after undergoing combined maze procedure and MVR + TAP due to pulmonary infection and sepsis, but the other 13 patients survived. Nine patients (69%) regained atrial rhythm, two patients (15%) had junctional rhythm and another two (15%) remained in AF at follow-up periods between 1 to 11.5 months (6.3 +/- 3.1). The nine patients who recovered to normal sinus rhythm had preoperative f-wave for a significant higher voltage than the patients with AF and JR (0.27 +/- 0.12 vs 0.13 +/- 0.05 mV, p < 0.05) and a smaller left atrial dimension (44.5 +/- 0.7 vs 54.8 +/- 6.9 mm, p < 0.05). These data suggest that the maze operation is effective and should be considered for patients with chronic AF indicated for surgical valvular diseases.

    One of the complications of using a synthetic material as a patch in correction of left-to-right shunts is the development of infection. This is an autopsy report of 13 patients who developed infective endocarditis of the Dacron patch as a postoperative complication. We retrospectively reviewed the autopsy records of patients with infective endocarditis over a 15-year period (1994-2008) and selected cases with Dacron-patch infective endocarditis. The patch infective endocarditis was classified into early-onset and late-onset infective endocarditis. Patch infective endocarditis was seen in 13 patients affecting the patches covering an atrial septal defect and 12 ventricular septal defects. There were nine males and four females, with a mean age of 13.1 years. The episodes occurred 2 to 118 days (mean of 30) after operation, with early-onset infective endocarditis in 10 and late-onset infective endocarditis in three patients. Postoperative wound infection had been present in eight. The organisms isolated or demonstrated on microscopy included Staphylococcus aureus (5), gram-positive cocci (4), Pseudomonas (2), Aspergillus species (1), and Candida species (1). Death was related to embolization and/or accompanying septicemia. Correction of simple or complex congenital cardiac defects offers new substrates for organisms to colonize resulting in infective endocarditis, which are often difficult to treat.

    Full Text Available Infective endocarditis is a lethal and challenging multifaceted disease that can involve any vascularized system. We believe that multimodality imaging is invaluable to provide a comprehensive diagnosis. Our management approach to infective endocarditis adheres to a combination of the AHA, ACC, STS, and ESC guidelines. With the rapidly increasing transcatheter valve population, we expect an increased caseload of infective endocarditis. Beyond patients with hemorrhagic strokes, we advocate for early surgery if medical management has failed. Furthermore, a multidisciplinary team approach is imperative in infective endocarditis, and clear communication reduces the time to diagnosis and definitive treatment for this patient population.

    Cerebral complications are well-identified causes of morbidity and mortality in patients with infective endocarditis (IE). Few studies have analysed the impact of brain magnetic resonance imaging (MRI) in IE patients with neurological manifestations. The aims of this study were to assess the MRI contribution to the management of patients with IE neurological manifestations and to compare cerebral CT and MRI findings. Patients with definite or probable IE and neurological manifestations were prospectively enrolled from 2005 to 2008, in a university hospital (Bichat Claude Bernard Hospital, Paris). Clinical and radiological characteristics and echocardiographic findings were systematically recorded. Brain MRI with angiography was performed and compared to available CT scans. The contribution of MRI results to cerebral involvement staging and to therapeutic plans was evaluated. Thirty patients, 37-89 years old, were included. Nineteen suffered from pre-existing heart disease. Blood cultures were positive in 29 cases and the main micro-organisms were streptococci (n = 14) and staphylococci (n = 13). The IE was mainly located on mitral (n = 15) and aortic valves (n = 13). Neurological events were strokes (n = 12), meningitis (n = 5), seizures (n = 1), impaired consciousness (n = 11) and severe headache (n = 1). MRI findings included ischaemic lesions (n = 25), haemorrhagic lesions (n = 2), subarachnoid haemorrhage (n = 5), brain abscess (n = 6), mycotic aneurysm (n = 7), vascular occlusion (n = 3) and cerebral microbleeds (n = 17). In 19/30 cases, neurological manifestations were observed before the diagnosis of IE. MRI was more sensitive than CT scan in detecting both clinically symptomatic cerebral lesions (100 and 81%, respectively) and additional asymptomatic lesions (50 and 23%, respectively). Therapeutic plans were modified according to MRI results in 27% of patients: antibiotherapy regimen modifications in 7% (switch for molecules with high cerebral diffusion

    Full Text Available Valvular strands are known to be a potential source of cardioembolism but the natural history of native valvular strands has not yet been fully outlined. We report a case of ischemic stroke in a patient with a native valvular strand of the aortic valve and the patient’s clinical course. A previously healthy 21-year-old man suffered acute cerebral infarction in the right posterior cerebral artery territory. On echocardiography, there was a strand-like, oscillating mass on the left coronary cusp of the aortic valve. The patient received 100 mg aspirin daily and the valvular strand was not found on subsequent transthoracic echocardiography performed 10 days after the first examination. Serial echocardiographic examinations have been performed since the stroke and failed to find any abnormality. The patient did not suffer a recurrent stroke over a 3-year follow-up period.

    Thrombotic thrombocytopenic purpura (TTP) is a life-threatening illness that occurs in both pregnant and non-pregnant women. Several other conditions can mimic the disease, which makes the diagnosis challenging. We describe a case of severe Staphylococcus aureus endocarditis that initially presented as peripartum TTP in a 39-year-old woman at 29+6 weeks' gestation. We give an overview of the diagnostic considerations and management of thrombocytopenia in pregnancy and review the literature related to TTP and peripartum infective endocarditis. Given the significant differences in definitive therapies for the spectrum of thrombocytopenic conditions that occur in pregnancy, timely and accurate diagnosis of TTP is critical for optimal management.

    Brucellosis is not frequent in Chile but it may present with life threatening complications like endocarditis. The case reported refers to a 74 year old man admitted to the Infectious Diseases Hospital Dr. Lucio Córdova in Santiago. He had been febrile for 3 months with no specific symptoms. The trans-esophageal echocardiography confirmed multiple large vegetations and important involvement of the aortic valve. Blood cultures yielded Brucella abortus. The patient required cardiac surgery, along with antibiotics, and he had a satisfactory outcome, being alive at the moment of this report???. Brucellosis can be the responsible for prolonged fever of unknown origin. It is necessary to take in mind brucellosis to obtain the specific laboratory tests. For a best prognosis an early treatment with associated antibiotics for at least 4 a 6 weeks is important. If endocarditis is present valve replacement is often necessary.

Cardiac involvement may be present in 50 to 60% of the patients. This is known as Löffler endocarditis. We present a case of a 36-year-old Hispanic man with signs of heart failure. Laboratory studies showed eosinophilia (23,100/μL. Thoracic computer tomography showed bilateral pleural effusion and a large left ventricular mass. Transthoracic echocardiography showed left ventricle apical obliteration and a restrictive pattern. Pulmonary angiography demonstrated a thrombus in the lingular and middle lobe. Despite treatment, the patient deceased seven days after admission. Autopsy confirmed the diagnosis of Löffler endocarditis.

    The study included 62 patients with uncomplicated primary and secondary infectious endocarditis admitted to S.PBotkin city hospital from 2011 to 2014. The emphasis is laid on diagnostic significance of dynamic measurements of the levels of C-reactive protein, tumour necrosis factor and highly sensitive troponin-1 for the evaluation of activity of the infectious/toxic process, severity of the disease, and detection of complications. The study revealed the relationship of the enhanced level of troponin-1 with changes of inflammation markers, morphofunctional characteristics of myocardium, and circulatory failure. Morphologicl study demonstrated inflammatory and dystrophic changes in myocardium, focal and diffuse cardiofibrosis suggesting development of non-coronarogenic myocardial lesions that play an important role in the progress of cardiac failure associated with infectious endocarditis.

    Full Text Available Streptococcus parasanguinis is a natural member of oral flora. It is an opportunistic pathogen, and rarely cause systemic infections due to it's low virulence. Subacute infective endocarditis may present with various clinical manifestations (eg., spondylodiscitis. A sixty-five years old male patient from Northern Iraq has referred to our emergency service with high fever, weight loss, back pain and inability to walk. The patient was a veterinarian. He was operated three years ago for colonic carcinoma and irradiated. In magnetic resonance imaging, spondylodiscitis was detected localized in lumbar 1-2 region. Transthorasic echocardiography demonstrated aortic valve vegetation. S. parasanguinis was identified in the blood cultures. In conclusion; all in all, it's remarkable to isolate S. parasanguinis as a causal agent of infective endocarditis in a patient who is a veterinarian with history of colonic carcinoma presented with clinical manifestation of spondylodiscitis.

    Full Text Available Bilateral endogenous endophthalmitis is a rare condition initiated by infection by microbes in the bloodstream, such as those arising from a foci of infective endocarditis. We report a case and discuss the diagnostic aspects and the clinical outcome of a patient with characteristic findings of the disease. The patient was a 49 year old white male who had a metallic aortic valve implanted 7 months previously, and who presented to the hospital with 10 days of fever, cough and dyspnea, then diarrhea and mental confusion. On the second day of hospitalization, he experienced sudden loss of vision in both eyes. A Gram-positive coccobacillus was isolated from the bloodstream, he was treated with fluoroquinolone with disappearance of fever, decreased ocular inflammation, and improvement in his vision to light perception. He later underwent valve replacement surgery but died during the procedure. We review the occurrence of ocular signs and symptoms and their importance in patients with endocarditis.

    Full Text Available Infective endocarditis is a microbial infection of the endocardial surface of the heart. Its symptoms and signs are varied, and include fever, heart murmur, peripheral embolism, and heart failure. The diagnosis of subacute bacterial endocarditis (SBE is suggested by a history of an indolent process characterized by fever, fatigue, anorexia, and unexplained weight loss. These patients may have had an invasive procedure, such as dental work, or abused intravenous drugs prior to the diagnosis of SBE. Although uncommon, the patients may present with nonspecific symptoms caused by peripheral embolic events. Herein, we report a 25-year-old male diagnosed with SBE, who presented with the unusual symptom of sudden onset of left upper quadrant abdominal pain for 2 days. His clinical history is also discussed.

    Rotavirus may cause life-threatening complications in untreated patients during the course of gastroenteritis. Electrolyte imbalance, bacteremia and sepsis are the most common complications of rotavirus gastroenteritis (RG). It is believed that translocation of intestinal microorganisms as a result of intestinal epithelium dysfunction is the underlying mechanism of bacteremia in RG. Although Gram-negative bacteremia has been noted as a complication in RG, Staphylococcus aureus bacteremia and endocarditis have not been reported previously. A 22-month-old boy was admitted with complaints of fever, diarrhea and dehydration. He was diagnosed with RG complicated with S. aureus bacteremia, pyomyositis and endocarditis. We call attention to these complications in patients with prolonged or late-onset fever during RG as rare complications of the disease. © 2015 Japan Pediatric Society.

    Valvular heart diseases are of increasing importance among the general adult population. When compared with other heart diseases, there are few trials in the field of valvular heart disease and randomized clinical trials are particularly scarce. Two sets of guidelines exist: one in the USA and the other in Europe. However, they are not always consistent due to the lack of randomized data and it appears that, frequently, there is a gap between the existing guidelines and their effective application.

    A clear correlation expressed by the following equation was observed between the preoperative left ventricular end-systolic eccentricity (epsilon s) and the percentage change of the left ventricular dimension (% delta D) in chronic valvular heart diseases: % delta D = 88.37 epsilon s - 48.16 (r = 0.66, p less than 0.001). Therefore, epsilon s may function as an index for predicting the postoperative cardiac performance independent of the affected valvular locations and the morphology of the lesions.

    The rarity of invasiveness of right-sided infective endocarditis (IE) compared with left-sided has not been well recognized and evaluated. Thus, we compared invasiveness of right- versus left-sided IE in surgically treated patients. From January 2002 to January 2015, 1292 patients underwent surgery for active IE, 138 right-sided and 1224 left-sided. Among patients with right-sided IE, 131 had tricuspid and 7 pulmonary valve IE; 12% had prosthetic valve endocarditis. Endocarditis-related invasiveness was based on echocardiographic and operative findings. Invasive disease was rare on the right side, occurring in 1 patient (0.72%; 95% confidence interval 0.02%-4.0%); rather, it was limited to valve cusps/leaflets or was superficial. In contrast, IE was invasive in 408 of 633 patients with aortic valve (AV) IE (65%), 113 of 369 with mitral valve (MV) IE (31%), and 148 of 222 with AV and MV IE (67%). Staphylococcus aureus was a more predominant organism in right-sided than left-sided IE (right 40%, AV 19%, MV 29%), yet invasion was observed almost exclusively on the left side of the heart, which was more common and more severe with AV than MV IE and more common with prosthetic valve endocarditis than native valve IE. Rarity of right-sided invasion even when caused by S aureus suggests that invasion and development of cavities/"abscesses" in patients with IE may be driven more by chamber pressure than organism, along with other reported host-microbial interactions. The lesser invasiveness of MV compared with AV IE suggests a similar mechanism: decompression of MV annulus invasion site(s) toward the left atrium.

    Full Text Available Autopsy incidence of infective endocarditis during the past 50 years was analysed to review the changes in the clinico-pathologic pattern if any. 185 cases were recorded in a total of 39931 autopsies giving an average incidence of 0.46%. The cases were classified into groups I, II & III depending upon whether the endocarditis super-vened on normal hearts, diseased hearts or followed surgery, re-spectively. The fifty year period could be divided into three phases on incidence. First phase (1927-41 represented pre-antibiotic era in which group I cases predominated and causative organisms in 801" o f cases were virulent cocci such as staphylococci, haemolytic streptococci and pneumococci. In the second phase (1948-66 the general incidence was reduced by 50%. Group II cases predominat-ed and the most common etiologic agent was streptococcus viridans (40%. In the third phase (1967-76 the general incidence has reached again to preantibiotic level with coagulase positive staphy-lococci, Gram negative bacilli and fungi accounting for 90% of cases. Group III contributed significantly in this phase. The changes in incidence are primarily due to fall and rise in Group I cases. Incidence of rheumatic heart disease with endocar-ditis which mainly forms Group II is declining steadily in post-antibiotic era. There is no shift in the peak age incidence which remains in the 3rd decade. Males with rheumatic heart disease are more prone to infective endocarditis than similarly affected females. There was no change in frequency of involvement of various valves or sites of embolization.

    Full Text Available Mycobacterium abscessus is an unusual cause of infection in immunocompetent patients. The intrinsic and acquired resistance of this organism to multiple antibiotics is a major issue in planning treatment regimens. We report a case of M. abscessus endocarditis of the native aortic valve in an immunocompetent patient following coronary angiography with a fatal outcome. The case highlights an unfortunate intervention - related nosocomial infection and the difficulties in chemotherapeutic options for this organism, particularly in the presence of renal failure.

    Full Text Available Objective: We have retrospectively analyzed the results of the operations made for aortic valve endocarditis in a single center in 26 years. Methods: From June 1985 to January 2011, 174 patients were operated for aortic valve endocarditis. One hundred and thirty-eight (79.3% patients were male and the mean age was 39.3±14.4 (9-77 years. Twenty-seven (15.5% patients had prosthetic valve endocarditis. The mean duration of follow-up was 7.3±4.2 years (0.1-18.2 adding up to a total of 1030.8 patient/years. Results: Two hundred and eighty-two procedures were performed. The most frequently performed procedure was aortic valve replacement with mechanical prosthesis (81.6%. In-hospital mortality occurred in 27 (15.5% cases. Postoperatively, 25 (14.4% patients had low cardiac output and 17 (9.8% heart block. The actuarial survival rates for 10 and 15 years were 74.6±3.7% and 61.1±10.3%, respectively. In-hospital mortality was found to be associated with female gender, emergency operation, postoperative renal failure and low cardiac output. The long term mortality was significantly associated with mitral valve involvement. Male gender was found to be a significant risk factor for recurrence in the follow-up. Conclusion: Surgery for aortic valve endocarditis has significant mortality. Emergency operation, female gender, postoperative renal failure and low cardiac output are significant risk factors. Risk for recurrence and need for reoperation is low.

    Recent studies suggest that treatment of heart failure (HF) could improve cardiac function and sleep apnea syndrome (SAS), but it is unknown how cardiac surgery may affect SAS in HF patients. Relationships between HF with valvular heart diseases and 2 types of SAS (obstructive sleep apnea (OSA) and central sleep apnea (CSA)) were examined. The effects of valve repair surgery on OSA and CSA was also investigated. Polysomnography, echocardiography and right cardiac catheterization were used to study 150 severe HF patients with mitral valvular and/or aortic valvular diseases. Significant associations between SAS and age, gender, body mass index, or hypertension were observed. The value of the CSA-apnea index (AI) was significantly correlated with pulmonary capillary wedge pressure (PCWP) and mean pulmonary artery pressure (PAP). These associations were not identified for OSA-AI. Valve repair surgery was used to treat 74 patients with severe SAS. The treatment led to a significant improvement in PCWP and mean PAP, and CSA-AI, but not in OSA-AI. These findings suggest close associations between CSA and cardiac function in HF patients with valvular heart diseases. Furthermore, improvement of cardiac function with valvular surgery reduces the severity of CSA in HF patients with valvular heart diseases.

    We report a case of fulminant endocarditis on a prosthetic homograft aortic valve caused by Bordetella holmesii, which was successfully managed by surgical valve replacement and antibiotic treatment. B. holmesii, a strictly aerobic, small, Gram-negative coccobacillus, has been implicated as an infrequent cause of a pertussis-like syndrome and other respiratory illnesses. However, B. holmesii is also a rare cause of septicaemia and infective endocarditis, mostly in immunocompromised patients. To our knowledge, this is the first report of B. holmesii endocarditis on a prosthetic aortic valve. Routine laboratory testing initially misidentified the strain as Acinetobacter sp. Correct identification was achieved by 16S rRNA gene and outer-membrane protein A (ompA) gene sequencing. Interestingly, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry also produced an accurate species-level identification. Subsequent susceptibility testing and review of the literature revealed ceftazidime, cefepime, carbapenems, aminoglycosides, fluoroquinolones, piperacillin/tazobactam, tigecycline and colistin as possible candidates to treat infections caused by B. holmesii.

    Full Text Available Systemic lupus erythematosus (SLE is a multisystemic autoimmune disease resulting from immune system-mediated tissue damage. Clinical findings of SLE can involve skin, kidney, central nervous system, cardiovascular system, serosal membranes, and the hematologic and immune systems. In the differential diagnosis, other connective tissue diseases, infective endocarditis, infections such as viral hepatitis, endocrine disorders such as hypothyroidism, sarcoidosis, and some malignant tumors should be considered. Infective endocarditis can imitate all the symptoms of SLE depending on immune complex accumulation glomerulonephritis. Hemolytic anemia, skin lesions, arthralgia, arthritis, decreased complement levels, and autoantibody positivity, including antinuclear autoantibody (ANA, positivity can be seen. Therefore, high fever, blood cultures, eye examination, and echocardiographic findings are of particular value. Here, we present a case of SLE that was confused with infective endocarditis (IE due to the presence of high fever associated with autoimmune hemolytic anemia (AHA and proteinuria as well as increased erythrocyte sedimentation rate (ESR, cardiac murmur, and Roth’s spots.

    1990-01-01

    The in vivo efficacy of daptomycin, a new cell wall-active anti-gram-positive-bacterial agent, was compared to those of cloxacillin and vancomycin in a rat model of Staphylococcus aureus endocarditis. Both methicillin-susceptible S. aureus (MSSA) and methicillin-resistant S. aureus (MRSA) strains were used. When therapy was initiated early (8 h) after infection, at the time when valvular bacterial counts were relatively low (approximately 10(6) CFU/g of vegetation), 3 days of therapy was found to be effective against the MSSA strains whatever the antibiotic regimen. In contrast, when the onset of therapy was delayed up to 15 h after infection, so that higher bacterial counts could develop on the valves (approximately 10(9) CFU/g of vegetation), a longer period of treatment (6 days) was required to cure infection. Under these conditions after 3 days of therapy, daptomycin was more effective than cloxacillin and vancomycin against the MSSA strains. Similarly, daptomycin showed a greater activity than vancomycin against the MRSA strain after 3 days of treatment, but after 6 days both antibiotics were equally effective. Decreasing doses of daptomycin showed decreasing activity: 10 mg/kg of body weight every 12 h (q12h) was better than 5 mg/kg q12h, whereas 5 mg/kg q24h (providing drug levels in blood detectable only during the first 12 h) failed to cure infection. In vitro, daptomycin was highly bactericidal at high concentrations (25 and 60 micrograms/ml, corresponding to peak levels in serum after doses of 5 and 10 mg/kg, respectively) and bacteriostatic at lower concentrations (0.5 to 2.5 micrograms/ml, corresponding to trough levels in serum). In conclusion, against low-bacterial-count S. aureus endocarditis, daptomycin showed an efficacy similar to those of vancomycin and cloxacillin. Against high-bacterial-count S. aureus endocarditis, daptomycin showed a higher bactericidal activity than cloxacillin (against the MSSA strains) and vancomycin (against both the

    Valvular heart diseases are not usually regarded as a major public-health problem. Our aim was to assess their prevalence and effect on overall survival in the general population. We pooled population-based studies to obtain data for 11 911 randomly selected adults from the general population who had been assessed prospectively with echocardiography. We also analysed data from a community study of 16 501 adults who had been assessed by clinically indicated echocardiography. In the general population group, moderate or severe valve disease was identified in 615 adults. There was no difference in the frequency of such diseases between men and women (p=0.90). Prevalence increased with age, from 0.7% (95% CI 0.5-1.0) in 18-44 year olds to 13.3% (11.7-15.0) in the 75 years and older group (p<0.0001). The national prevalence of valve disease, corrected for age and sex distribution from the US 2000 population, is 2.5% (2.2-2.7). In the community group, valve disease was diagnosed in 1505 (1.8% adjusted) adults and frequency increased considerably with age, from 0.3% (0.2-0.3) of the 18-44 year olds to 11.7% (11.0-12.5) of those aged 75 years and older, but was diagnosed less often in women than in men (odds ratio 0.90, 0.81-1.01; p=0.07). The adjusted mortality risk ratio associated with valve disease was 1.36 (1.15-1.62; p=0.0005) in the population and 1.75 (1.61-1.90; p<0.0001) in the community. Moderate or severe valvular diseases are notably common in this population and increase with age. In the community, women are less often diagnosed than are men, which could indicate an important imbalance in view of the associated lower survival. Valve diseases thus represent an important public-health problem.

    Prophylaxis and treatment guidelines for infective endocarditis have changed substantially over the past decade. In the United States, few population-based studies have explored the contemporary epidemiology and outcomes of endocarditis. To quantify trends in the incidence and etiologies of infective endocarditis in the United States. Retrospective population epidemiology study of patients hospitalized with a first episode of endocarditis identified from mandatory state databases in California and New York State between January 1, 1998, and December 31, 2013. Infective endocarditis. Outcomes were crude and standardized incidence of endocarditis and trends in patient characteristics and disease etiology. Trends in acquisition mode, organism, and mortality were analyzed. Among 75 829 patients with first episodes of endocarditis (mean [SD] age, 62.3 [18.9] years; 59.1% male), the standardized annual incidence was stable between 7.6 (95% CI, 7.4 to 7.9) and 7.8 (95% CI, 7.6 to 8.0) cases per 100 000 persons (annual percentage change [APC], -0.06%; 95% CI, -0.3% to 0.2%; P = .59). From 1998 through 2013, the proportion of patients with native-valve endocarditis decreased (from 74.5% to 68.4%; APC, -0.7%; 95% CI, -0.9% to -0.5%; P 1998 through 2013, with changes in patient characteristics and etiology over this time.

  14. Is there a need for bacterial endocarditis prophylaxis in patients undergoing gastrointestinal endoscopy?

    2014-04-01

    Heart valve repair or replacement is a serious problem. Patients can benefit from an open dialogue between both cardiologists and gastroenterologists for the optimal effective patients care. The focused update on infective endocarditis of the American College of Cardiology/American Heart Association 2008 (ACC/AHA guidelines) and guidelines on the prevention, diagnosis, and treatment of infective endocarditis (new version 2009) of the European Society of Cardiology (ESC guidelines) describe prophylaxis against infective endocarditis (IE) as not recommended for gastroscopy and colonoscopy in the absence of active infection but increasing evidence suggests that the role of IE antibiotic prophylaxis remains a dark side of the cardio-oncology prevention. New evidences concerning infective endocarditis due to Streptococcus bovis, Streptococcus agalactiae, Enterococcus faecalis, Enterococcus faecium, Enterococcus durans, and new findings indicate that there is a need for bacterial endocarditis prophylaxis in patients undergoing gastrointestinal endoscopy especially in elderly patients and in cancer and immunocompromised patients, to avoid serious consequences.

    Full Text Available Introduction. Enterococcus faecalis (E. faecalis, a constituent of the gut microbiota, can be associated with both colonic lesions and endocarditis. Since this microorganism is one of the endocarditis etiological agents, there is a need for greater study in regard to the association with endocarditis and colonic lesions. Case Presentation. This is the case description of a 53-year-old man with history of prolapse of the anterior mitral valve leaflet who was diagnosed with endocarditis by E. faecalis and treated with ampicillin and gentamicin. Upon investigation by colonoscopy, he was found to have a tubular adenoma with low grade dysplasia. Conclusion. There are a few descriptions in scientific literature of an association between endocarditis by E. faecalis and colonic lesions. However, further studies with significant correlation between the two pathologies are required, so that proper measures can be implemented in clinical practice.

    Isolated infectious endocarditis of the pulmonary valve is a rare condition and represents 1,5-2% of all cases of infectious endocarditis. We present a case of a 37year-old woman without any relevant medical history. The woman was hospitalized with hallmarks of severe sepsis and bilateral pneumonia; she died several hours after admission with progressive multiorgan failure and disseminated intravascular coagulopathy. Microbiologic examination approved Staphylococcus aureus as the etiological agent. The autopsy showed isolated endocarditis of the pulmonary valve, without any known predisposing factor. Literary data refer single cases or small groups of patients with isolated pulmonary infectious endocarditis. The clinical suspicion of this rare disease in differential diagnosis of febrile conditions is an essential factor in prognosis of afflicted persons. The crucial diagnostic methods for infectious endocarditis are echocardiography and CT examination.

    The objective of this study was to study cardiac valve morphology and function and ventricular function in systemic lupus erythematosus (SLE) patients with and without co-existing cardiovascular disease (CVD) and in population controls. Twenty-six women (52 +/- 8.2 years) with SLE (SLE cases) and a history of CVD (angina pectoris, myocardial infarction, cerebral infarction or intermittent claudication) were compared with 26age-matched women with SLE but without manifest CVD (SLE controls) and 26 age-matched control women (population controls). Echocardiographywas performed to assess valvular abnormalities and manifestations of ischaemic heart disease. Thirteen of the 26 SLE cases but only one of the SLE controls and one of the population controls had cardiac valvular abnormalities. Three of the SLE cases had already undergone valve replacement and another had significant aortic insufficiency; the other nine had thickening of mainly mitral leaflets without hemodynamic significance. Among SLE cases, patients with valvular abnormalities had higher homocysteine (P valvular disease. In contrast atherosclerosis as determined by IMT, oxidized LDL as measured by the monoclonal antibody E06, autoantibodies against epitopes of OxLDL (aOxLDL) or phospholipids (aPL), disease duration or activity, or acute phase reactants did not differ between SLE cases with or without valvular abnormalities. Valvular abnormalities were not more common in SLE cases with stroke as compared to those with myocardial infarction, angina or claudication. In conclusion, valvular abnormalities are strongly associated with CVD in SLE. Raised levels of homocysteine and triglycerides characterize patients with cardiac valve abnormalities.

    In a period of 5 years there were 18,391 admissions; out of them 1129 cases were diagnosed with valvular lesions: 223 (19.7%) were degenerative valvular heart disease, 608 (53.8%) had rheumatismal valvular lesions, 7 (0.6%) had congenital valvular lesions and 291 cases (25.7%) had valvular lesions of other etiologies. Out of the 223 cases with degenerative valvular lesions, 99 cases (44.4%) were men with an average age of 70.1 years old and 129 were women (55%) with an average age of 74.9 years old. The calcific aortic valve stenosis was encountered in 139 patients (62.3%), the aortic insufficiency was diagnosed in 19 patients (8.5%), the mitral insufficiency 49 patients (21.9%) and the mitral stenosis in 10 patients (4.4%) the other patients having either aortic or mitral valvular disease. The combination of an aortic stenosis with a mitral insufficiency was diagnosed in 46 cases (20.6%) from the 223. Only 14 patients were asymptomatic, most of them having heart failure (namely, 178 patients i.e. 78%) with or without angine pectoris or effort vertigo, or they had only effort angina, vertigo or effort sincope. Rhythm disorders happened in 59 patients (26.4%) while disorders in the transmission of the stimuli were diagnosed in 14 patients (5.2%). Two patients died due to cardiac causes. Rheumatismal valve disease are nearly 2.5 times more frequent than degenerative valve disease and they became a practical reality, which is claimed by its continuously increasing frequency, by a variety of lesional aspects and by implications on the heart, and by it, presence in an age group were arteriosclerosis cumulates its risk factors.

    2017-06-01

    Patients undergoing cardiac valve replacement may receive mechanical or bioprosthetic valves. Mechanical valves require lifelong anticoagulation but are durable and the need for a second surgery is up to eightfold times less than with bioprosthetic valves. Bioprosthetic valves do not require lifelong anticoagulation and thus are associated with fewer bleeding complications but they are less durable and associated with higher morbidity and mortality rates, particularly in younger patients. Anticoagulation with mechanical valves is achieved using warfarin; use of direct-acting oral anticoagulants is not indicated. Concomitant low-dose aspirin is recommended for patients with mechanical valves and as sole thromboembolism prophylaxis for patients receiving aortic or mitral bioprosthetic valves. If a patient taking warfarin is to undergo a surgical procedure that requires interruption of anticoagulation, bridging therapy with heparin is indicated if the patient has a mechanical aortic valve and any risk of thromboembolism, an older-generation mechanical aortic valve, or a mechanical mitral valve. Warfarin is teratogenic; pregnant women should take heparin. Patients with mechanical or bioprosthetic valves should receive antibiotic prophylaxis before some dental and surgical procedures to prevent endocarditis. Thrombolytic therapy should be considered in patients who develop a thrombus on a valve that does not resolve with heparin.

    2017-08-01

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

    Patients with valvular heart disease (VHD) should be treated for diabetes, hypertension, and hyperlipidemia. They also should receive therapy for left ventricular dysfunction, undergo interval echocardiography, and participate in aerobic exercise. Valve replacement should be considered for patients with aortic stenosis (AS) and syncope, presyncope, heart failure, angina, or severe AS with left ventricular dysfunction. Valve replacement is performed with open or transcatheter procedures; the latter are preferred for patients with high surgical risk. Patients with chronic aortic regurgitation (AR) should undergo open surgical replacement if they are symptomatic or are asymptomatic but have severe regurgitation and left ventricular dysfunction. No transcatheter procedures currently are approved for AR. Patients with mitral stenosis (MS) should receive drugs for heart rate control and anticoagulation if they have atrial fibrillation. Invasive treatment involves valve replacement or percutaneous commissurotomy. Management of severe chronic mitral regurgitation consists of valve replacement or, for patients with high surgical risk, a percutaneous transcatheter procedure that clips the mitral leaflets together. When severe, tricuspid regurgitation can be managed with valve replacement. Pregnant patients with VHD require special management. Women with severe AS or MS should avoid becoming pregnant until VHD is managed definitively.

  2. Ileal neuroendocrine tumors and heart: not only valvular consequences.

    2015-04-01

    Ileal neuroendocrine tumors (NETs) often progress slowly, but because of their generally nonspecific symptoms, they have often metastasized to local lymph nodes and to the liver by the time the patient presents. Biochemically, most of these patients have increased levels of whole blood serotonin, urinary 5-hydroxyindoleacetic acid, and chromogranin A. Imaging work-up generally comprises computed tomography or magnetic resonance imaging and somatostatin receptor scintigraphy, or in recent years positron emission tomography with 68Ga-labeled somatostatin analogs, allowing for detection of even sub-cm lesions. Carcinoid heart disease with affected leaflets, mainly to the right side of the heart, is a well-known complication and patients routinely undergo echocardiography to diagnose and monitor this. Multitasking surgery is currently recognized as first-line treatment for ileal NETs with metastases and carcinoid heart disease. Open heart surgery and valve replacement are advocated in patients with valvular disease and progressive heart failure. When valvulopathy in the tricuspid valve results in right-sided heart failure, a sequential approach, performing valve replacement first before intra-abdominal tumor-reductive procedures are conducted, reduces the risk of bleeding. Metastases to the myocardium from ileal NETs are seen in heart metastases are detected, with the addition of diuretics and fluid restriction in cases of heart failure. Myocardial metastases are rarely treated by surgical resection.

Durante los últimos 20 años la técnica quirúrgica ha evolucionado hacia una menor agresión corporal, apareciendo nuevos tipos de cirugía aórtica mínimamente invasiva (CMIAo. De todas estas técnicas, la hemiesternotomía superior (HES, o miniesternotomía, se ha convertido en la más utilizada, seguida por la minitoracotomía anterior derecha (MTA. Ambas, comparadas con la cirugía convencional, han demostrado una recuperación más rápida, mejor resultado cosmético, menor estancia hospitalaria y en UCI, mejor función respiratoria, menor pérdida de sangre y transfusiones, e incluso menor mortalidad precoz y tardía. A pesar de estos avances, su uso no se ha extendido definitivamente debido a un incremento en los tiempos de isquemia y de circulación extracorpórea (CEC necesarios en estos procedimientos más complejos. La aparición de las prótesis sin sutura «Sutureless» de nueva generación puede solventar este contratiempo al reducir hasta en un 43% los tiempos de isquemia y CEC, y permitir que la CMIAo se expanda y sea una alternativa real a las válvulas transcatéter (TAVI en los pacientes de alto riesgo operables. A pesar de que son recomendables ensayos clínicos prospectivos aleatorizados para confirmar estos datos, existe suficiente evidencia disponible como para considerar la CMIAo (sobre todo la HES como el gold standard actual para la sustitución valvular aórtica aislada.

    Rheumatic heart disease is the most common cause of valvular heart disease throughout the world. Echocardiography is the dominant imaging investigation in the assessment of cardiac valvular disease and the role of Magnetic Resonance Imaging (MRI) is so far limited. However, due to rapid improvements in the cardiac MRI technology in past few years, this non invasive technique is gaining interest in the examination of cardiac valves. Our study was undertaken to define the role of MRI in the evaluation of Rheumatic valvular heart disease and to compare the role of MRI with transthoracic echocardiography with regard to quantity of stenosis and volume regurgitation. ECG gated Cardiac MRI was performed with a 1.5-Tesla system (MAGNETOM SYMPHONY- Model 2005) using basic cardiac software (Argus viewer) by a phased-array multicoil on 50 subjects who were known cases of Rheumatic valvular heart disease. A chest radiograph and echocardiography were done in all patients before MR examination. Informed consent was taken from all patients. Mitral stenosis either as an isolated valvular abnormality or in combination with other valvular abnormalities constituted the major bulk of Rheumatic valvular heart disease in our study population. The average ejection fraction by ECHO is 64.94±7.11 and by MRI 67.52±7.84. The average mitral valve area by ECHO is 1.79±0.43 cm(2) and by MRI 1.82±0.47 cm(2). The average aortic valve area by ECHO is 1.10±0.21 cm(2) and by MRI 1.12±0.25 cm(2). The Coefficient of Correlation (r) is 0.82 for ejection fraction, 0.98 for mitral valve area and 0.92 for aortic valve area which means a strong positive association between the results by ECHO and MRI. In all instances, the p-value is <0.00001, suggesting that the test is highly significant. In our study echocardiography was found to be the gold standard for the diagnosis of Rheumatic valvular heart disease and the role of MRI remained only complimentary to Echocardiography.

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

    Mycobacterium goodii is an infrequent human pathogen which has been implicated in prosthesis related infections and penetrating injuries. It is often initially misidentified as a gram-positive rod by clinical microbiologic laboratories and should be considered in the differential diagnosis. We describe here the second reported case of M. goodii endocarditis. Species level identification was performed by 16S rDNA (ribosomal deoxyribonucleic acid) gene sequencing. The patient was successfully treated with mitral valve replacement and a prolonged combination of ciprofloxacin and trimethoprim/sulfamethoxazole. Confirmation of the diagnosis utilizing molecular techniques and drug susceptibility testing allowed for successful treatment of this prosthetic infection.

In addition, the potential detrimental effect of valvular heart disease on the activities of daily living is unknown. The present study evaluated the prevalence of significant valvular heart disease and the impact of valvular heart disease on the activities of daily living in community dwelling nonagenarians. Nested within the Leiden 85-plus study, a ...

    Infective endocarditis is a rare diagnosis in pediatrics. Group A beta-hemolytic Streptococcus pyogenes is known to cause a range of type and severity of infections in childhood. However, S. pyogenes is a rarely described cause of endocarditis in children. This paper presents two cases of S. pyogenes endocarditis and the largest and most up-to-date review of cases previously reported in the literature. Here we describe two pediatric cases of S. pyogenes endocarditis with associated toxic shock. Case 1 was a previously well Caucasian 6-year-old female who presented with sepsis. Case 2 was an 8-month-old South Asian female who presented with sepsis and pneumonia. We present a review of the literature since the beginning of the antibiotic era of this unusual cause of bacterial endocarditis in children. In addition to the two cases presented here, a total of 13 children have been reported since 1940 with endocarditis caused by S. pyogenes for which clinical details are available. Although few cases exist, literature review reveals a high mortality rate (27%) and the majority of patients who recovered had residual morbidities. We emphasize the importance of considering a diagnosis of endocarditis in cases of S. pyogenes sepsis or toxic shock in order to ensure early diagnosis and timely treatment, which are necessary for good outcomes. This information is relevant to both general and subspecialty pediatricians, especially emergency room and infectious disease physicians.

    Case series have suggested that pneumococcal endocarditis is a rare disease, mostly reported in patients with co-morbidities but no underlying valve disease, with a rapid progression to heart failure, and high mortality. We performed a case-control study of 28 patients with pneumococcal endocarditis (cases), and 56 patients with non-pneumococcal endocarditis (controls), not matched for sex and age, during the years 1991-2013, in one referral centre. Alcoholism (39.3% versus 10.7%; p endocarditis. Cardiac surgery was required in 64.3% of patients with pneumococcal endocarditis, much earlier than in patients with non-pneumococcal endocarditis (mean time from symptom onset, 14.1 ± 18.2 versus 69.0 ± 61.1 days). In-hospital mortality rates were similar (7.1% versus 12.5%). Streptococcus pneumoniae causes rapidly progressive endocarditis requiring life-saving early cardiac surgery in most cases.

    Although atrial fibrillation (AF), a common arrhythmia, frequently presents in patients with underlying valvular disease, its hemodynamic contributions are not fully understood. The present work aimed to computationally study how physical conditions imposed by pathologic valvular anatomy act on AF hemodynamics. We simulated AF with different severity grades of left-sided valvular diseases and compared the cardiovascular effects that they exert during AF, compared to lone AF. The fluid dynamics model used here has been recently validated for lone AF and relies on a lumped parameterization of the four heart chambers, together with the systemic and pulmonary circulation. Three different grades of severity (mild, moderate, severe) were analyzed for each of the four valvulopathies (aortic stenosis, mitral stenosis, aortic regurgitation, mitral regurgitation). Regurgitation was hemodynamically more relevant than stenosis, as the latter led to inefficient cardiac flow, while the former introduced more drastic fluid ...

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

    Objectives To determine the hospitalization rates and outcomes of endocarditis among older adults. Background Endocarditis is the most serious cardiovascular infection and is especially common among older adults. Little is known about recent trends for endocarditis hospitalizations and outcomes. Methods Using Medicare inpatient Standard Analytic Files, we identified all Fee-For-Service beneficiaries aged ≥65 years with a principal or secondary diagnosis of endocarditis from 1999-2010. We used Medicare Denominator Files to report hospitalizations per 100,000 person-years. Rates of 30-day and 1-year mortality were calculated using Vital Status Files. We used mixed-effects models to calculate adjusted rates of hospitalization and mortality and to compare the results before and after 2007, when the American Heart Association revised recommendations for endocarditis prophylaxis. Results Overall, 262,658 beneficiaries were hospitalized with endocarditis. The adjusted hospitalization rate increased from 1999-2005, reaching 83.5 per 100,000 person-years in 2005, and declined during 2006-2007. After 2007, the decline continued, reaching 70.6 per 100,000 person-years in 2010. Adjusted 30-day and 1-year mortality rates ranged from 14.2% to 16.5% and from 32.6% to 36.2%, respectively. There were no consistent changes in adjusted rates of 30-day and 1-year mortality after 2007. Trends in rates of hospitalization and outcomes were consistent across demographic subgroups. Adjusted rates of hospitalization and mortality declined consistently in the subgroup with principal diagnosis of endocarditis. Conclusions Our study highlights the high burden of endocarditis among older adults. We did not observe an increase in adjusted rates of hospitalization or mortality associated with endocarditis after publication of the 2007 guidelines. PMID:23994421

    Diagnosis and treatment of infective endocarditis (IE) is still a challenge for physicians. Group of patients with the worst prognosis is treated in Intensive Cardiac Care Unit (ICCU). Etiologic agent can not be identified in a substantial number of patients. The aim of study is to find differences between patients with blood culture negative infective endocarditis (BCNIE) and blood culture positive infective endocarditis (BCPIE) treated in ICCU by comparing their clinical course and laboratory parameters. Retrospective analysis of 30 patients with IE hospitalized in ICCU Swietokrzyskie Cardiac Centre between 2010 and 2016. This group consist of 26 men (86,67%) and 4 women (13,3%). Mean age was 58 years ±13. Most of the cases were new disease, recurrence of the disease was observed in 2 cases (6,7%). 8 patients (26,7%) required artificial ventilation, 11 (36,7%) received inotropes and 6 (20%) vasopresors. In 14 (46,7%) cases blood cultures was negative (BCNIE), the rest of patients (16, 53,3%) was blood cultures - positive infective endocarditis (BCIE). Both of the groups were clinically similar. There were no statistically significant differences in incidence of cardiac implants, localization of bacterial vegetations, administered catecholamines, antibiotic therapy, artificial ventilation, surgical treatment, complication and in-hospital mortality. Incidence of cardiac complications in all of BCNIE cases and in 81,3% cases of BCPIE draws attention, but it is not statistically significant difference (p=0,08). There was statistically significant difference in mean BNP blood concentration (3005,17 ng/ml ±2045,2 vs 1013,42 ng/ml ±1087,6; p=0,01), but there were no statistically significant differences in rest of laboratory parameters. BCNIE group has got higher mean BNP blood concentration than BCPIE group. There were no statistically significant differences between these groups in others laboratory parameters, clinical course and administered antibiotic therapy

    Rheumatic heart disease (RHD) is a chronic condition characterized by fibrosis and scarring of the cardiac valves and damage to the heart muscle, leading to congestive heart failure and death. This prospective cohort study was conducted to investigate the possible relation between the levels of serum adhesion molecules and acute rheumatic fever (ARF) carditis, valvular insult severity, and residual valvular lesion after improvement of rheumatic activity. Serum levels of intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin were assayed by enzyme-linked immunoassay (ELISA) for 50 children with ARF carditis during activity and after improvement and for 50 healthy children as control subjects. After the acute attack, patients were followed up regularly to detect residual valvular lesion. The serum levels of these adhesion molecules were significantly higher in the patients than in the control group (p valvular lesion (ICAM-1, >1,032.3 μg/ml; VCAM-1, >3,662.3 μg/ml; E-selectin, >104.8 μg/ml). Finally, by combining the three adhesion molecules in a single prediction model, the highest area under the curve (AUC) ± standard error (SE) was obtained (0.869 ± 0.052), and the positive likelihood ratio for having a residual valvular lesion was increased (17.33). Levels of serum adhesion molecules could predict residual valvular lesions in RHD patients. The authors recommend that the serum level of adhesion molecules be measured in all cases of ARF carditis.

    Rheumatic heart disease (RHD) is the most important sequela of rheumatic fever (RF): evidence that streptococcal infection is aetiological is prominent, but sometimes contradictory. Acute HSV-1 infection in mouse leads to carditis and valvulitis whereas recurrent infection results in inflammatory granulomatous lesions that resemble Aschoff bodies. Cells containing HSV-1 inclusions or virus infected giant cells appear similar to Anitschkow cells or Aschoff cells respectively. We hypothesized that HSV-1 infection also may be involved in RHD. Formalin-fixed, paraffin-embedded valvular tissue samples from 32 patients with RHD were investigated for evidence of HSV-1 infection. HSV-1 antigen was detected by immunohistochemistry, using HSV-1-specific monoclonal and polyclonal antibodies. HSV-1 glycoprotein D gene sequences were amplified by nPCR, using beta-globin gene amplification in the same samples as internal control. Valvular tissue from 5 cases of sudden death and 3 cases died of neisseria meningitis without a history of valvular disease was used for comparison. HSV-1-infected lung tissue was used as positive control. HSV-1 antigens were detected in valvular tissues from 21 of 32 (65.6%) patients. Fifteen of these 21 (46.9% of cases), but no antigen-negative sample, were positive also for HSV DNA. Nucleotide sequence of PCR products was homologous to the targeted region of the HSV-1 glycoprotein D gene. HSV-1 antigen was present also in one case of sudden death but viral DNA was not found in any tissue sample from the comparison group. Results from reagent and positive controls were as anticipated. This is the first study to show the presence of HSV-1 antigen and genomic DNA in valvular tissues from patients with RHD and provides evidence for an association of HSV-1 infection with some cases of rheumatic valvular disease.

The fluid dynamics model used here has been recently validated for lone AF and relies on a lumped parameterization of the four heart chambers, together with the systemic and pulmonary circulation. The AF modelling involves: (i) irregular, uncorrelated and faster heart rate; (ii) atrial contractility dysfunction. Three different grades of severity (mild, moderate, severe) were analyzed for each of the four valvulopathies (AS, aortic stenosis, MS, mitral stenosis, AR, aortic regurgitation, MR, mitral regurgitation), by varying–through the valve opening angle–the valve area. Results: Regurgitation was hemodynamically more relevant than stenosis, as the latter led to inefficient cardiac flow, while the former introduced more drastic fluid dynamics variation. Moreover, mitral valvulopathies were more significant than aortic ones. In case of aortic valve diseases, proper mitral functioning damps out changes at atrial and pulmonary levels. In the case of mitral valvulopathy, the mitral valve lost its regulating capability, thus hemodynamic variations almost equally affected regions upstream and downstream of the valve. In particular, the present study revealed that both mitral and aortic regurgitation strongly affect hemodynamics, followed by mitral stenosis, while aortic stenosis has the least impact among the analyzed valvular diseases. Discussion: The proposed approach can provide new mechanistic insights as to which valvular pathologies merit more aggressive treatment of

    Full Text Available Twenty-two cases of nocardial infections were diagnosed in our city between 1977- 1998. All patients whose clinical specimens showed Nocardia spp. at Gram stain, which were further confirmed by culture, were selected to be included in the study. Data from patients who were cured were compared with those from patients who died by statistical tests using EPIINFO version 6.04 software. Six isolates were identified as Nocardia asteroides complex, one as Nocardia asteroides sensu stricto and other as Nocardia brasiliensis. We had 17 cases of lung nocardiosis, being one out of them also a systemic disease. Other four cases of systemic nocardiosis were diagnosed: nocardial brain abscesses (one; nocardiosis of the jejunum (one; multiple cutaneous abscesses (one; and a case of infective nocardial endocarditis of prosthetic aortic valve. One patient had a mycetoma by N. brasiliensis. Fifteen (68.2% out of 22 patients were immunosuppressed, being most (93.3% by high-doses corticotherapy. Mortality by nocardial infection was 41%; mortality of systemic nocardiosis was 60%. Nocardiosis has a bad prognosis in immunosuppressed patients and also in non-immunosuppressed patients if the diagnosis is delayed. We propose that the delay in diagnosis should be examined in larger series to document its influence in the prognosis of the disease.São apresentados 22 casos de infecção por Nocardia species entre 1977 e 1998, apresentando-se seu quadro clínico e evolução. Todos os pacientes cujos espécimes clínicos mostraram microorganismos sugestivos de Nocardia spp. à coloração de Gram, confirmados posteriormente por cultura, foram incluídos no estudo. Os dados dos pacientes que obtiveram cura foram comparados com aqueles dos pacientes que foram a óbito pelo programa EPIINFO versão 6.04; nível de significância menor que 5% foi considerado estatisticamente significativo.

    Full Text Available Rothia aeria is an uncommon pathogen mainly associated with endocarditis in case reports. In previous reports, endocarditis by R. aeria was complicated by central nervous system embolization. In the case we report herein, endocarditis by R. aeria was diagnosed after acute self-limited diarrhea. In addition to the common translocation of R. aeria from the oral cavity, we hypothesize the possibility of intestinal translocation. Matrix-assisted laser desorption ionization-time of flight mass spectrometry and genetic sequencing are important tools that can contribute to early and more accurate etiologic diagnosis of severe infections caused by Gram-positive rods.

    Infective endocarditis (IE) one-year mortality rates approach 40%. Here, we report two native valve Enterococcus faecalis IE cases in patients successfully treated with telavancin. An 88-year-old with mitral valve endocarditis and a penicillin allergy, initially treated with intravenous vancomycin, was switched to telavancin. A 69-year-old, who previously received amoxicillin and intravenous vancomycin for presumed enterococcal bacteraemia, was diagnosed with dual valve endocarditis for which he received telavancin. Both received six weeks of telavancin. Neither had telavancin-related adverse events, evidence of infection at six months, nor required telavancin dosing adjustments. Documented use of novel treatments for serious enterococcal infections is needed.

    To assess the prevalence of gastrointestinal neoplasia in patients with Streptococcus bovis infectious endocarditis we performed a retrospective cohort analysis of all episodes of S. bovis infectious endocarditis treated at our institution between January 2000 through December 2014. Twenty-five patients were identified for this purpose. 12/25 patients received colonoscopy and 1/25 of the patients was assessed with CT colonography. Of the 13 who underwent colonic assessment, 11 were diagnosed with colonic neoplasms at different stages of development. In the absence of any strong contraindication, gastroenteroscopic evaluation in all patients diagnosed with S. bovis infectious endocarditis should be pursued.

    Infectious endocarditis patients occasionally need emergency cardiac surgery even if they have a tracheostoma. However, a median full-sternotomy approach carries increased risk for sternal infection and lethal mediastinitis in cardiac surgery for patients with tracheostomas. We successfully performed valve replacement procedures using a lower partial median sternotomy approach in 6 infectious endocarditis patients with tracheostomas. There were neither operative deaths nor complications related to wound infection in these cases. The partial sternotomy approach represents a safe alternative in cardiac surgery for acute infectious endocarditis patients with tracheostomas who need emergent surgery.

    Full Text Available HACEK endocarditis is often difficult to diagnose given the slow-growing characteristics of the organisms involved. Haemophilus parainfluenzae, one of the HACEK organisms, is an uncommon cause of endocarditis. We describe a case of a previously healthy young man with H parainfluenzae endocarditis that was associated with maxillary sinusitis and severe systemic complications, including septic cerebral emboli and mitral valve perforation. Previously reported cases have also described a predilection for younger people, cardiac valve pathology, and a high prevalence of stroke.

    The genus Ruminococcus which are anaerobe Gram positive cocci, previously classified as Peptostreptococcus, may colonize the upper respiratory tract, gastrointestinal tract, vagina and skin of humans and animals. In this report a case of liver abscess and a case of infective endocarditis caused by Ruminoccocus productus, which is very rarely encountered in the clinical practice were presented. The first case was a 32 years old male who was admitted to the hospital in 2002, with the complaints of fever lasting for 20 days and pain while breathing. The abdominal ultrasonography revealed the presence of a liver abscess, and the drainage material from the abscess yielded Ruminococcus productus, identified in BACTEC 9200 (Becton Dickinson, Sparks, Md) anaerobe system. As the isolate was found to be sensitive to penicilin, the empirical gentamicin and ampicillin/sulbactam therapy was continued. The second case was a 25 years old male who was admitted to the hospital in 2005, with the signs of fever lasting for 3-4 months, chills, bone and joint pains. As multiple vegetations were detected in echocardiography, blood cultures were collected and empirical therapy with ceftriaxone and gentamicin was initiated with the preliminary diagnosis of infective endocarditis. Bacteria which were isolated from blood cultures by BACTEC 9200 system have been identified as R. productus. As this strain was also sensitive to penicillin, the empirical therapy was changed to penicilin and gentamicin. These two cases indicated that R. productus should be considered in complicated infections even if it is a rarely isolated species from the clinical samples.

    Full Text Available Abstract Background There are few reports in the literature of invasive infection caused by Brevundimonas vesicularis in patients without immunosuppression or other predisposing factors. The choice of antimicrobial therapy for bacteremia caused by the pathogen requires more case experience to be determined. Case presentation The case of a 40-year-old previously healthy man with subacute endocarditis proposed to be contributed from an occult dental abscess is described. The infection was found to be caused by B. vesicularis on blood culture results. The patient recovered without sequelae after treatment with ceftriaxone followed by subsequent ciprofloxacin therapy owing to an allergic reaction to ceftriaxone and treatment failure with ampicillin/sulbactam. Conclusion To our knowledge, this is the first report of B. vesicularis as a cause of infective endocarditis. According to an overview of the literature and our experience, we suggest that third-generation cephalosporins, piperacillin/tazobactam, and ciprofloxacin are effective in treating invasive B. vesicularis infections, while the efficacy of ampicillin-sulbactam needs further evaluation.

    Because neurological failure is the most frequent extra-cardiac complication in Infectious Endocarditis (IE), a brain computerised tomography (CT) scan is usually performed. The benefits of magnetic resonance imaging (MRI) have not been clearly established. This study aims to clarify the prevalence and type of cerebral lesions in IE detected using MRI and to compare them with those detected using CT scans. In the Grenoble University Hospital, patients diagnosed with definite or possible endocarditis according to Duke's criteria were screened from 2010-2012. Brain CT and MRI were performed as soon as possible after diagnosis. Of the 62 patients with IE who underwent at least one cerebral imaging within 3 weeks of diagnosis, Streptococcus (29) and Staphylococcus (14) were the main micro-organisms present. Twenty-eight (45%) patients underwent cardiac surgery. Eight (13%) died before discharge. Twenty (32%) had neurological symptoms. A brain CT-scan was performed on 53 (85%) patients and a MRI was performed on 43 (69%) patients. CT was pathological in 26 (49%) patients, whereas 32 (74%) MRI demonstrated abnormalities. The MRI lesions were classified as follows: ischaemia (48%), microbleeds (34%), haemorrhages (16%), abscesses (9%) and microbial aneurysms (4%). Of the 37 patients who underwent both MRI and CT examinations, ischaemia (48% vs 35%) and microbleeds (34%) demonstrated the difference between the two imaging methods. Through the early diagnosis of cerebral damage, even in asymptomatic cases, MRI may have a role in the IE management, influence any surgical decision and assist in prognosis assessment.

    Thirty-five year-old Amadeus Mozart died in Vienna after an acute illness that lasted only 15 days but no consensus has been reached on the cause of his death. From many letters written by his farther it is almost certain that he experienced at least three episodes of acute rheumatic fever attack in his childhood, and a relapse of rheumatic fever was suggested to have killed Mozart, although death from acute rheumatic fever is very rare in adults. His last illness was characterized by high fever, massive edema, vomiting and skin rash. His last illness can be explained by infectious endocarditis and heart failure. During his last hours, he was given phlebotomy, possibly for the third time in two weeks, and soon after he became unconscious and died. As such, phlebotomy performed on a man dehydrated by high fever and vomiting may have caused systemic shock. In summary, Mozart probably died from chronic rheumatic heart disease complicated by infective endocarditis and heart failure, and repeated phlebotomy-induced hypovolemic shock.

    Bacillus cereus is a ubiquitous telluric organism. B. cereus endocarditis is a rare condition seen mostly in prosthetic heart valves and among intravenous drug users. We report a new case of a patient without risk factors and with a good clinical outcome not requiring valve replacement. In October 2014, a 50-year-old woman was referred to the dermatology department of Lille University Hospital for lower-limb wounds developing 6 months earlier. She presented fever without clinical signs of infection, except for the lower-limbs wounds. Blood cultures revealed the presence of B. cereus. Transesophageal echocardiography was performed and revealed two foci of aortic valve vegetation with a diameter of 5mm. After bacterial sensitivity testing, rifampicin and levofloxacin treatment was given for six weeks, with complete remission. A skin graft was performed and good improvement was seen. Nineteen cases of B. cereus endocarditis have been described previously, only one of which was without risk factors. We described a case of complete remission after a 6-week course of antibiotics. Our case demonstrates that BC should not be considered as a blood culture contamination, and that treatment may be complex due to antibiotic resistance. Copyright © 2016 Elsevier Masson SAS.

  16. Antibiotic prophylaxis in infective endocarditis: Use or abuse?

    Full Text Available Introduction: The American Heart Association (AHA recommendations for antimicrobial prophylaxis for infective endocarditis (IE are controversial. According to the new guidelines released by the AHA now, the only patients to receive antibiotics will be those at highest risk, i.e. those with a prosthetic heart valve, a history of endocarditis, certain forms of congenital heart disease or valvulopathy after heart transplantation, and only before certain dental procedures. Unfortunately, these guidelines are still based largely on expert opinion, with very little hard evidence to show that antibiotic therapy actually prevents IE. The Hypothesis: The reported incidence of bacteremia during dental intervention ranges from 10% to 100% and, with daily brushing and flossing, from 20% to 68%. Because bacteremia also occurs during brushing and flossing of teeth, why give prophylaxis just for dental procedures? Moreover, the risks of causing adverse or anaphylactic reactions from antibiotics as well as contributing to the nationwide antibiotic resistance problem are issues not to be taken lightly. Evaluation of the Hypothesis: The hypothesis discusses the AHA recommendations for antimicrobial prophylaxis for IE, indicating some inherent limitations associated with it, and stresses upon the fact that these recommendation should also be updated, if not completely changed, to cope up with the advancements in the proper treatment plan.

  17. Marvelous but Morbid: Infective endocarditis due to Serratia marcescens

    A 46-year-old man with HIV infection and active intravenous drug use presented with approximately two weeks of fevers and body aches. On physical examination he was somnolent, had a new systolic murmur, bilateral conjunctival hemorrhages, diffuse petechiae, and left-sided arm weakness. Echocardiography revealed a large mitral valve vegetation and brain imaging demonstrated numerous embolic infarctions. Blood cultures grew Serratia marcescens. Despite aggressive treatment with meropenem the patient died due to intracranial hemorrhage complicated by herniation. Serratia marcescens is an uncommon cause of infective endocarditis. While this disease has historically been associated with intravenous drug use, more recent reports suggest that it is now largely a consequence of opportunistic infections of the chronically ill. Our case highlights several characteristic features of this infection, including isolation of a non-pigmented strain of the organism, an antibiotic susceptibility profile suggestive of AmpC β-lactamase production, and rapid clinical deterioration with multiple embolic complications resulting in death. In this review we discuss the history, epidemiology, and management of endovascular infections due to Serratia spp., emphasizing the continued importance of considering this organism in the differential diagnosis of endocarditis among intravenous drug users and as a potential indication for surgical therapy.

    A viridans streptococcus (Streptococcus sanguis biotype II) isolated from the blood of a patient with subacute bacterial endocarditis was examined for protease production. In broth culture, extracellular proteolytic enzymes were not produced by this organism until after the early exponential phase of growth, with maximal protease production occurring during the stationary phase. Four distinct proteases were isolated and purified from the supernatant fluids of stationary-phase cultures, employing a combination of ion-exchange column chromatography, gel filtration column chromatography, and polyacrylamide gel electrophoresis. All four proteases could be eluted from a diethylaminoethyl cellulose column at a sodium chloride gradient concentration of 0.25 M but were separable by gel filtration chromatography on a Sephadex G-100 column. They varied in molecular weights as determined by gel filtration and sodium dodecyl sulfate-polyacrylamide gel electrophoresis from approximately 13,000 to 230,000. All four proteases had pH optima of between 8.0 and 9.0, and two of the proteases were active against casein, human serum albumin, and gelatin but were not active against elastin and collagen. The remaining two proteases were able to degrade only casein and gelatin. These results show that S. sanguis is able to excrete maximal levels of potentially destructive enzymes when the organisms are not actively multiplying. This finding may explain some of the damage caused in heart tissue by these organisms during subacute bacterial endocarditis. Images PMID:6759404

Among patients with right-sided IE, 131 had tricuspid and 7 pulmonary valve IE; 12% had prosthetic valve endocarditis. Endocarditis-related invasiveness was based on echocardiographic and operative findings. RESULTS......: Invasive disease was rare on the right side, occurring in 1 patient (0.72%; 95% confidence interval 0.02%-4.0%); rather, it was limited to valve cusps/leaflets or was superficial. In contrast, IE was invasive in 408 of 633 patients with aortic valve (AV) IE (65%), 113 of 369 with mitral valve (MV) IE (31......%), and 148 of 222 with AV and MV IE (67%). Staphylococcus aureus was a more predominant organism in right-sided than left-sided IE (right 40%, AV 19%, MV 29%), yet invasion was observed almost exclusively on the left side of the heart, which was more common and more severe with AV than MV IE and more common...

    Infective endocarditis is rare in children, it is rarer after a surgical treatment of atrioventricular canal, and it is exceptional that Candida albicans is the etiologic agent. This is a serious infection found in congenital heart disease with or without surgery. It is potentially lethal, despite diagnostic and therapeutic advances. We report a case of infective endocarditis due to C. albicans after the treatment of a congenital systemic atrioventricular canal in a child with trisomy 21. The diagnosis was suspected on clinical manifestations and cardiac auscultation. Confirmation was provided by positive blood cultures and echocardiography. The large size of the vegetation in the patient was in favor of a fungal etiology, blood cultures allowed to identify the fungus. This observation illustrates a poorly understood disease, with very poor prognosis and which is a potential complication of heart surgery. The improved prognosis should be achieved by shortening the time to diagnosis and optimizing the therapeutic support. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Full Text Available Despite advances in therapy, infective endocarditis (IE remains a serious disease with high mortality. We evaluated 155 Egyptian patients with Duke definite/possible IE to determine incidence, causes and predictors of inhospital mortality. The mean time from symptoms onset to diagnosis was 66.4 ± 97 days. The causes of mortality (38.7% included congestive heart failure (CHF, sepsis, surgery related, stroke, cerebral hemorrhage, pulmonary embolism, sudden cardiac death, and hyperkalemia. Predictors of mortality on univariate analysis were duration of symptoms before hospital admission (p = 0.017, health care associated endocarditis (p = 0.039, CHF (p < 0.001, fulminant sepsis (p < 0.001, embolization (p = 0.011, need for dialysis (p = 0.003, need for cardiac surgery (p = 0.027, unperformed indicated cardiac surgery (p = 0.002 and higher C-reactive protein level (p = 0.05. In multivariate analysis, only CHF remained an independent predictor of mortality (p = 0.033. IE mortality was high in this cohort probably due to delayed diagnosis. Patients having these mortality predictors especially CHF deserve more aggressive treatment.

    Early detection of infectious endocarditis is challenging. For diagnosing infectious endocarditis, the revised Duke criteria are the gold standard. Evidence of endocardial involvement on echocardiography is a major criterion, but sensitivity and specificity of echocardiography are not optimal. Here we investigated the utility of {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography and computed tomography (PET/CT) to diagnose infectious endocarditis in patients with gram-positive bacteraemia. Seventy-two patients with gram-positive bacteraemia were prospectively included. Patients with a positive blood culture growing Staphylococcus aureus, Streptococcus species or Enterococcus species were eligible when a risk factor for developing metastatic infectious foci was present. Infectious endocarditis was defined according to the revised Duke criteria.

    The pharmacokinetic determinants of successful antibiotic prophylaxis of endocarditis are not precisely known. Differences in half-lives of antibiotics between animals and humans preclude extrapolation of animal results to human situations. To overcome this limitation, we have mimicked in rats the amoxicillin kinetics in humans following a 3-g oral dose (as often used for prophylaxis of endocarditis) by delivering the drug through a computerized pump. Rats with catheter-induced vegetations we...

    One third of patients with infective endocarditis will require operative intervention. Given the superiority of valve repair over valve replacement in many indications other than endocarditis, there has been increasing interest and an increasing number of reports of excellent results of valve repair in acute infective endocarditis. The theoretically ideal material for valve repair in this setting is non-permanent, "vanishing" material, not at risk of seeding or colonization. The goal of this contribution is to review currently available data on biodegradable materials for valve repair in infective endocarditis. Rigorous electronic and manual literature searches were conducted to identify reports of biodegradable materials for valve repair in infective endocarditis. Articles were identified in electronic database searches of Medline, Embase and the Cochrane Library, using a predetermined search strategy. 49 manuscripts were included in the review. Prosthetic materials needed for valve repair can be summarized into annuloplasty rings to remodel the mitral or tricuspid annulus, and patch materials to replace resected valvar tissue. The commercially available biodegradable annuloplasty ring has shown interesting clinical results in a single-center experience; however further data is required for validation and longer follow-up. Unmodified extra-cellular matrix patches, such as small intestinal submucosa, have had promising initial experimental and clinical results in non-infected valve repair, although in valve repair for endocarditis has been reported in only one patient, and concerns have been raised regarding their mechanical stability in an infected field. These evolving biodegradable devices offer the potential for valve repair with degradable materials replaced with autologous tissue, which could further improve the results of valve repair for infective endocarditis. This is an evolving field with promising experimental or initial clinical results, however long

  2. Right-Sided Endocarditis due to Staphylococcus lugdunensis: First Reported Case

    1998-01-01

    Full Text Available Staphylococcus lugdunensis is a coagulase-negative organism first identified in 1988. It is often incorrectly identified as Staphylococcus aureus, and has been isolated as the etiological agent in over 20 cases of left-sided endocarditis. This report describes the first documented case of right-sided endocarditis caused by S lugdunensis. This experience suggests that S lugdunensis can infect native valves in the absence of any predisposing risk factors such as injection drug use.

    Early detection of infectious endocarditis is challenging. For diagnosing infectious endocarditis, the revised Duke criteria are the gold standard. Evidence of endocardial involvement on echocardiography is a major criterion, but sensitivity and specificity of echocardiography are not optimal. Here we investigated the utility of (18)F-fluorodeoxyglucose (FDG) positron emission tomography and computed tomography (PET/CT) to diagnose infectious endocarditis in patients with gram-positive bacteraemia. Seventy-two patients with gram-positive bacteraemia were prospectively included. Patients with a positive blood culture growing Staphylococcus aureus, Streptococcus species or Enterococcus species were eligible when a risk factor for developing metastatic infectious foci was present. Infectious endocarditis was defined according to the revised Duke criteria. All patients underwent (18)F-FDG PET/CT and echocardiography. (18)F-FDG uptake in or around the heart valves was evaluated independently by two nuclear medicine physicians. Sensitivity for diagnosing infectious endocarditis with (18)F-FDG PET/CT was 39% and specificity was 93%. The positive predictive value was 64% and negative predictive value was 82%. The mortality rate in patients without infectious endocarditis and without increased (18)F-FDG uptake in or around the heart valves was 18%, and in patients without infectious endocarditis but with high (18)F-FDG uptake in or around the heart valves the mortality rate was 50% (p = 0.181). (18)F-FDG PET/CT is currently not sufficiently adequate for the diagnosis of infectious endocarditis because of its low sensitivity. Improvements such as patient preparation with low carbohydrate-fat allowed diet and technical advances in the newest PET/CT scanners may increase sensitivity in future studies.

    Myocardial abscess formation in patients with bacterial endocarditis in most clinical settings, especially in patients with prosthetic valves, is a primary indicator for surgical valve replacement. We report the detection of myocardial abscesses using /sup 111/In leukocyte scintigraphy in three patients with prosthetic or native valve endocarditis and nondiagnostic echocardiograms. Leukocyte scintigraphy may allow identification of myocardial abscess formation earlier than other imaging modalities.

    Rheumatic heart disease (RHD) is a delayed consequence of a pharyngeal infection with Group A streptococcus (GAS), usually ascribed to a cross-reactive immune response to the host cardiac tissues. Acute rheumatic fever (ARF) and its ensuing valvular sequelae are thus considered the prototype of a post-infectious autoimmune disease, with no direct evidence of residual streptococcal antigen in diseased valvular tissues. However, recent studies concerning the antigenic specificity and clonality of intralesional lymphocytes have revealed oligoclonal expansions characteristic of an antigen specific response, that might be related to GAS. To search for bacterial DNA in valvular tissue from RHD patients and controls. We extracted DNA from surgically excised valve specimens from 15 RHD patients and 6 non RHD controls and tested for the presence of bacterial DNA by Polymerase Chain Reaction (PCR) with primers for 16S rRNA. Eighty percent (12/15) of valve specimens from RHD patients were positive for bacterial DNA, as opposed to none of the valves (n =6) from non RHD controls. These results suggest that GAS might persist in valvular tissue in patients with ARF and contribute to the inflammatory scarring lesion that leads to cardiovascular sequelae.

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

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

    The antiphospholipid syndrome (APS) leads to venous and arterial thrombosis, cardiac diseases, neurological, gastroenterological and dermatological complications. The role of antiphospholipid antibodies in genesis of thrombi by interaction with plasma clotting factors is well known. There is no evidence of their influence on valvular heart diseases or atherogenesis. This paper presents views and opinions about APS and related cardiovascular complications.

    To investigate the prevalence and epidemiological features of valvular heart disease (VHD) adult populations with different ethnicities in Xinjiang. A total of 14 618 adults aged 35 or older were surveyed. Random sampling was employed to study valvular heart diseases in different age, gender and ethnic groups. Samples were collected from 7 localities (Urumqi, Ke lamayi, Fukang, Turfan Basin, Hetian, Altay, Yili Hazakh Autonomous Prefecture) in 23 municipalities and 5 autonomous counties in Xinjiang. The proportion of male to female accounted for 50% each. The overall prevalence of valvular heart diseases was 7.67% (male: 7.31% vs. female: 8.00%). The prevalence rates of valvular heart diseases were 10.57%, 2.36% and 12.22% in Han, Uygur and Kazakh populations, respectively. The prevalence of valvular heart diseases was lower in Uygur than in Hazak and Han ethnic populations (χ(2) = 3.90, P = 0.000). Complications related to valvular heart diseases would include hypertension (63.20%), diabetes (7.60%), coronary heart disease (7.50%) and fibrillation atrial (3.20%). The prevalence of valvular heart diseases had a substantial increase, parallel with age. Differences were seen on the prevalence rates of VHD among ethnic populations.

    Full Text Available Abstract Introduction The main clinical manifestations of Whipple's disease are weight loss, arthropathy, diarrhea and abdominal pain. Cardiac involvement is frequently described. However, endocarditis is rare and is not usually the initial presentation of the disease. To the best of our knowledge, this is the first reported case of a patient with Tropheryma whipplei tricuspid endocarditis without any other valve involved and not presenting signs of arthralgia and abdominal involvement. Case presentation We report a case of a 50-year-old Caucasian man with tricuspid endocarditis caused by Tropheryma whipplei, showing signs of severe shock and an absence of other more classic clinical signs of Whipple's disease, such as arthralgia, abdominal pain and diarrhea. Tropheryma whipplei was documented by polymerase chain reaction of the blood and pleural fluid. The infection was treated with a combined treatment of doxycycline, hydroxychloroquine and sulfamethoxazole-trimethoprim for one year. Conclusion Tropheryma whipplei infectious endocarditis should always be considered when facing a blood-culture negative endocarditis particularly in right-sided valves. Although not standardized yet, treatment of Tropheryma whipplei endocarditis should probably include a bactericidal antibiotic (such as doxycycline and should be given over a prolonged period of time (a minimum of one year.

    Scedosporium prolificans is an emerging agent for severe infections. Although among the dematiaceous fungi Scedosporium is the most frequently isolated in blood cultures, Scedosporium endocarditis is rarely reported. We show herein a patient with acute leukaemia who developed S. prolificans endocarditis. Twelve cases were found in an extensive review of the English literature. In six cases (46%), there was predisposing heart conditions such as a prosthetic valve or an intracavitary device. Only 4 patients (31%) were immunocompromised hosts with haematologic neoplasia, solid-organ transplantation or acquired immunodeficiency syndrome (AIDS). Exposure to Scedosporium was observed in immunocompetent patients who developed infection while in the community. Scedosporium endocarditis occurred on both sides of the heart. Systemic and pulmonary emboli and other metastatic complications were seen in all of these patients. The overall mortality was 77% and, specifically, all of the immunocompromised hosts and 6 out of 7 patients with mitral or aortic valve endocarditis died. Patients with right-sided endocarditis associated with a removable intracardiac device exhibited a better prognosis. Scedosporium endocarditis, although still rare, is an emerging infection with an ominous prognosis. At the present time, valve replacement or the removal of cardiac devices plus combined antifungal treatment may offer the best possibility of cure.

    There are no experimental studies regarding the prophylactic efficacy of linezolid against infective endocarditis. Nonbacterial thrombotic endocarditis of the aortic valve was induced in rabbits by the insertion of a polyethylene catheter. Twenty-four hours later, animals were randomly assigned to a control group, and groups receiving either ampicillin (two doses of 40 mg/kg of body weight each, given intravenously, 2 h apart) or linezolid (a single per os dose of 75 mg/kg). The first dose of ampicillin and the single dose of linezolid were administered 0.5 and 1 h, respectively, prior to the intravenous inoculation of approximately 10(7) CFU of Streptococcus oralis or Enterococcus faecalis. Linezolid peak levels in rabbit serum were similar to the peak serum levels in humans following a 600-mg oral dose of linezolid. Linezolid prevented endocarditis in 87% of S. oralis-challenged rabbits (P faecalis, linezolid prevented endocarditis in 73% (P = 0.003 versus controls; P = 0.049 versus ampicillin). Ampicillin prevented endocarditis due to S. oralis or due to E. faecalis in 47% (P = 0.005 versus controls) and in 30% (P = not significant versus controls) of the challenged animals, respectively. In conclusion, linezolid was effective as prophylaxis against endocarditis caused by a strain of S. oralis and to a lesser degree against that caused by a strain of E. faecalis. Its prophylactic efficacy was superior to that of ampicillin.

    The increasing number of resistant bacterial strains in infective endocarditis (IE) emphasizes the need for a constant development of antimicrobials. Linezolid is an oxazolidinone with an effect on Gram-positive cocci. Only a few casuistic reports describe its utilization in the treatment of IE...... linezolid were antibiotic intolerance (n = 13), nephrotoxicity (n = 5), pharmaceutical interactions (n = 1), inadequate clinical response (n = 14), or inadequate microbial response (n = 5). No significant differences in the cure rate (74 % vs. 71 %, p > 0.05), in-hospital mortality (13 % vs. 14 %, p > 0.......05), or post-discharge mortality at 12 months follow-up (26 % vs. 26 %, p > 0.05) were observed. In the current study, we found that linezolid, in general, was well tolerated and associated with the same outcome as in patients with Gram-positive IE treated with other antibiotics....
