OBJECTIVES: For adequate management and therapy of infective endocarditis (IE), identification of the causative pathogen is crucial but currently molecular testing results are not included in diagnostic criteria. The added diagnostic value and impact on antimicrobial therapy of 16S rRNA PCR and Amplicon Sequencing (16S rRNA PCR) performed on excised heart valves from IE patients was evaluated alongside with the effect of pre-operative antibiotics on the performance of blood culture (BC), valve culture (VC) and 16S rRNA PCR...

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...

Embolic events from infective endocarditis can cause acute coronary syndrome. Mortality rate is high and optimal management might be different from those chosen in setting of classic atherosclerotic coronary artery disease. We present a case of 56-year-old male who had received 5 weeks of antibiotics for aortic valve endocarditis and developed acute ST segment elevation myocardial infarction in hospital settings. Interestingly, patient had recent left heart catheterization that was normal. This was recognized as embolic event from sterile vegetation...

Bicuspid aortic valve (BAV) or bicuspid aortopathy is the most common congenital heart disease. It can be clinically silent and it is often identified as an incidental finding in otherwise healthy, asymptomatic patients. However, it can be dysfunctioning at birth, even requiring neonatal intervention, or, in time, lead to aortic stenosis, aortic insufficiency, and endocarditis, and also be associated with aortic aneurysm and aortic dissection. Given its prevalence and significant complications, it is estimated that BAV is responsible for more deaths and morbidity than the combined effects of all the other congenital heart defects...

INTRODUCTION: Mycotic aneurysms are a serious complication of infective endocarditis with increased risk of intracranial hemorrhage. Patients undergoing open heart surgery for valve repair or replacement are exposed to anticoagulants, increasing the risk of aneurysm bleeding. These patients may require endovascular or surgical aneurysm treatment prior to heart surgery, but data on this approach are scarce. METHODS: Retrospective review of consecutive patients with infectious endocarditis and mycotic aneurysms treated endovascularly with Trufill n-butyl cyanoacrylate (n-BCA) at the Cleveland Clinic between January 2013 and December 2015...

BACKGROUND: The significance of and threshold values for the standardized uptake value (SUV) in FDG PET/CT to diagnose prosthetic heart valve (PHV) endocarditis (PVE) are unclear at present. METHODS: A literature search was performed in the PubMed and EMBASE medical databases, comprising the following terms: (FDG OR *fluorode* OR *fluoro-de*) AND (endocarditis OR prosthetic heart valve OR valve replacement). Studies reporting SUVs correlated to the diagnosis of PVE were selected for analysis...

Abiotrophia defectiva is nutritional deficient streptococci that cannot be cultured on routine culture medias. Even though fastidious in growth requirement, it is a virulent bacterium preferentially affecting endovascular structures and is implicated in many culture-negative endocarditis cases. Unlike other organisms, it is known for heart valve destruction leading to heart failure and excessive embolization rates. It's inherent resistance to routinely used antibiotics also contributed to increased mortality and morbidity in affected individuals and warrants timely diagnosis and prompt treatment...

Hemodialysis (HD) patients are more susceptible to infective endocarditis (IE) due to the increased risk of bacterial invasion through intravascular access. However, it remains unclear whether the causative organisms and outcomes of IE in HD patients differ from those in non-HD patients. This study clarified the differences in clinical presentation and outcomes between HD and non-HD patients. At our hospital, we performed a retrospective study of 39 HD and 51 non-HD patients with echocardiography-confirmed IE between June 2000 and February 2007...

With new surgical techniques, more and more complex congenital heart defects are treated requiring sometimes right ventricle to pulmonary artery conduit implantation. In order to extend RV to PA conduit lifespan, 15 years ago a valved stent was developed. The implantation technique was progressively standardized to decrease risks of procedural complications. Medium and long-term hemodynamic results of the stent were so good that indications were broadened to native or complex right ventricular outflow tracts...

BACKGROUND: Corynebacterium striatum is a member of the non-diphtherial corynebacteria, which are ubiquitous in nature and generally colonize the skin and mucous membranes of humans. Rarely, it causes infective endocarditis (IE). We report a case of rare left atrial bacterial vegetative mass due to C. striatum masquerading as a myxoma identified through a tortuous diagnostic process, and present a brief review of the relevant literature. CASE PRESENTATION: We present a case of 63-year-old man who presented with progressively worsening dyspnea on exertion and lower leg edema, and was diagnosed with heart failure...

Infective endocarditis (IE) is uncommon, however, the incidence is on the rise [1]. Despite improvements in its management, infective endocarditis (IE) is associated with significant short- and long-term morbidity and mortality [2]. A definitive diagnosis of IE may be challenging and is often delayed due to the highly variable and non-specific symptoms at patient presentation, alongside limited availability of specialist services [3]. In addition to IE remaining a diagnostic challenge, the decisions about the treatment modality (medical vs surgical) and the timing of potential valve surgery are demanding, despite established national and international guidelines [4]...

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 (18)F-FDG PET-CT scan ((18)F-fluorodeoxyglucose-positron emission tomography-computed tomography) scan was performed...
