Transesophageal echocardiography (TEE) is the gold standard imaging study used in the diagnosis of infective endocarditis (IE). Computed tomography angiography (CTA) has undergone rapid advancement as a cardiac imaging technique and has previously shown promise in small non-randomized studies for evaluation of IE. We hypothesized that cardiac CTA would perform similarly to TEE in the detection of endocarditic lesions and that there would be no difference in clinical outcomes whether the coronary arteries were evaluated by CTA or invasive coronary angiography (ICA)...

The unique aspect of this case study is the unusual history, presentation, ultrasonography, MRI and blood culture results, which lead to the diagnosis and treatment of adductor pyomyositis with a rare organism in a temperate country. The patient presented with a one-day history of malaise, fever, left groin pain and inability to weight bear on the left leg. There was no history of any trauma, predisposing infections or recent travel. Plain radiograph and ultrasound of the hip was normal with no effusion. Two consecutive blood cultures suggested Streptococcus mitis bacteraemia and MRI scan confirmed pyomyositis of the left hip adductors that was too small to drain...

Rhizobium radiobacter, a soil-based organism, is not, usually, pathogenic unless in the immunecompromised. Endocarditis, in the immunocompromised, is a typical presentation generally as a result of catheter-based infections. We describe the presentation of R. radiobacter prosthetic valve endocarditis and the inherent challenges in its presentation and diagnosis. A patient presented with acute limb ischemia secondary to R. radiobacter-mediated endocarditis and subsequent thromboembolization of the distal superior femoral and proximal popliteal arteries in the left lower limb...

Mitral annular caseoma is a common incidental finding involving the posterior annulus. It has an innocent nature, with the exception of its endocarditic degeneration and/or a stenotic functional effect when exophytic. We report an exceptionally rare isolated anterior mitral annular caseoma involving also the anterior mitral leaflet and affecting its physiologic systolic movement, thus resulting in a restricting anterior leaflet motion responsible for mitral insufficiency. The case was successfully treated by complex mitral valve repair...

Results of long-term prospective follow-up of patients with early stages of mitral and aortic valvulitis and primary chronic septic endocarditic are presented. Clinical diagnostics of the diseases is described and the key role is assigned to pathognomic (absolute) clinical symptoms. The tendency to progressive fibrosis of endocardial structures with subsequent gradual development of valve dysfunction and stenosis (especially for the mitral valve) is revealed. It is shown that early treatment increases the effective valve area and promotes reversion of mitral stenosis...

Surgical repair of congenital ventricular septal defects (VSDs) in adults is quite rare. Most congenital VSDs are repaired in children. Of those adult patients diagnosed as having VSDs, many are not repaired due to irreversible pulmonary vascular disease. Repair in a patient with a VSD and fistula is even more uncommon. From a review of the literature, we found no other case reports with our unique combination of echocardiographic and surgical findings: a supracristal VSD, right and left sinus of Valsalva fistulas into the right ventricular outflow tract, and a pulmonary artery to pulmonary vein fistula in the context of an aseptic endocarditis lesion...

There are only a few cases of prosthetic valve endocarditis (PVE) following transcatheter aortic valve implantation (TAVI) reported in the literature. Though not very frequent, this is a serious concern because patients are high risk for surgical aortic valve replacement (SAVR) by definition, and explanting the endocarditic prosthetic valve followed by SAVR increases risk even higher.

Infective endocardits of the tricuspid valve (TVIE) occurs mainly in addicted-intravenous drug users, in the presence of intracardiac electrodes or central venous catheters, and in some congenital heart diseases; rarely, in other conditions. The authors present a case of a 61-year-old male with TVIE as a result of complicated transurethral resection of bladder papilloma. The onset of TVIE was insidious, with low back pain, followed by pulmonary symptoms. Echocardiography showed large vegetations on the tricuspid valve; blood culture was positive for methycylin-resistant, coagulase-negative staphylococcus...

Enterococci are among the major pathogens implicated in cardiac infections and biofilm formation. E. faecalis has been shown to play an important role in infectious endocarditis. Several distinct mechanisms for biofilm formation have been identified in E. faecalis. Our group has previously characterized two distinct bacterial glucosyltransferases playing key roles in the production of the major cell wall glycolipids and leading to reduced biofilm production. To assess if this mechanism is involved in the pathogenesis of enterococcal endocarditis we compared the wild-type strain of E...

We are reporting the first case of rare association between multiple congenital cardiac malformations with severe rheumatic mitral stenosis which is an acquired structural cardiac disease. A 16 years old female patient presented with progressive dyspnoea & cyanosis for the last one month with past history of recurrent pneumonia since infancy. Physical examination revealed presence of cyanosis, grade I clubbing, radio-radial & radio-femoral delay, loud & single second heart sound, apical long mid diastolic murmur and left parasternal ejection systolic murmur...

INTRODUCTION: Streptococcus bovis can lead to bacteraemia, septicaemia, and ultimately endocarditis. The objective of this study was to evaluate the long-term implications of S. bovis endocarditis on cardiac morbidity and mortality. METHODS: A retrospective cohort study was performed between January 2000 and March 2009 to assess all patients diagnosed with S. bovis bacteraemia from the Belfast Health and Social Care Trust. The primary end-point for cardiac investigations was the presence of endocarditis...

Prevention of infective endocardit s (IE) is mportant because it has a high mortalty rate.This study sets out to to gather information from patients who were at risk of developing IE of their knowledge of the need for prophylaxis for the disease. Forty-one black patients suffering from severe rheumatic heart disease (RHD) were interviewed. Only one patient (2.4%) was regularly visiting a dentist to maintain good oral health and only five (12.2%) had received advice about the need for antibiotic cover prior to dental extraction...

A case of pacemaker electrode infection with Staphylococcus aureus is presented. In order to avoid sternotomy, the right ventricular pacemaker lead, which had been implanted for 15 years, was successfully extracted using a laser sheath despite large endocarditic vegetations on the pacemaker lead. After completion of a 6-week course of antibiotics, the patient was discharged without any further evidence of infection.

OBJECTIVE: Degenerative or post-endocarditic destruction of aortic valves with secondary left ventricular hypertension and cardiac insufficiency is seen more frequently in patients of increasing age. When conventional aortic valve replacement is no longer an option, because of age and co-morbidity, patients are increasingly treated with interventional aortic valve replacement using transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: TAVI has been performed in Cologne since 2008...

OBJECTIVE: Granted that minimally invasive mitral valve (MV) surgery short-term results were found to be equivalent to those achieved with traditional sternotomy with respect to perioperative morbidity and echocardiographic outcomes, little is known about the long-term efficacy of this approach. This report analyzes a 10-year single-surgeon experience with minimally invasive MV surgery through a right minithoracotomy with peripheral cannulation and external aortic cross-clamping and MV repair (MVR) by direct vision...

Surgical site infections are a common complication of obstetric and gynaecological surgeries; up to 10% of gynaecological patients undergoing an operative procedure will develop a surgical site infection. In surgeries with high rates of post-operative infection, antibiotic prophylaxis (using an antibiotic with an appropriate microbiological spectrum and administered in a timely manner) can play a major role in improving outcomes. This review examines the medical literature to assess the indications and appropriate antibiotic choices for prophylaxis to prevent surgical site infection in obstetric and gynaecological surgery...

BACKGROUND: The modified Bentall procedure remains a gold standard of aortic root surgery. We present in this study the early and late outcomes of a particular modification using 2 separated grafts for the coronary reimplantation. METHODS: From 1995 to 2009, 153 patients aged 57±12 (mean±standard deviation [SD]) underwent elective (n=113) or urgent (n=40) aortic root replacement with a composite mechanical valve conduit reconstruction using 2 short, separated 8-mm Dacron grafts for the coronary reimplantation and were retrospectively reviewed...
