REVIEW
Elżbieta K Biernacka, Witold Rużyłło, Marcin Demkow
Percutaneous pulmonary valve implantation (PPVI) is a relatively new method of treating patients with right ventricular outflow tract (RVOT) dysfunction after surgical repair of congenital heart disease. Since its introduction in 2000 by Bonhoeffer, more than ten thousand PPVI procedures have been performed worldwide. Indications for PPVI have been adapted from those accepted for surgical intervention. Two types of valves are being used: Melody Medtronic available in diameters 16 mm and 18 mm and the family of Edwards SAPIEN valves 23, 26 and 29...

Yassamine Bentata
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%...

Staphylococcus aureus causes many infections, such as skin and soft tissue, pneumonia, osteomyelitis, and infective endocarditis (IE). IE is an endovascular infection of native and prosthetic valves and the lining of the heart; it is characterized by the formation of cauliflower-like "vegetations" composed of fibrin, platelets, other host factors, bacteria, and bacterial products. β-Toxin is an S. aureus virulence factor that contributes to the microorganism's ability to cause IE. This cytolysin has two enzymatic activities: sphingomyelinase (SMase) and biofilm ligase...

PURPOSE OF REVIEW: Infective endocarditis in children remains a clinical challenge. Here, we review the impact of the updated 2015 American Heart Association and European Society of Cardiology guidelines on management as well as the significance of the new predisposing factors, diagnostic and treatment options, and the impact of the 2007-2008 change in prophylaxis recommendations. RECENT FINDINGS: The new 2015 infective endocarditis guidelines introduced the endocarditis team, added the new imaging modalities of computer tomography and PET-computer tomography into the diagnostic criteria and endorsed the concept of safety of relatively early surgical treatment...

BACKGROUND: (18)F-Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) has been recently acknowledged as a diagnostic tool for prosthetic valve endocarditis, but its specificity is limited by uptake on noninfected valves. The objective of this study was to outline the main features of FDG uptake on PET/CT in patients with noninfected prosthetic heart valve (PHV). METHODS AND RESULTS: Our institution's PET/CT database was reviewed to identify patients with PHV, excluding those suspected of infection or who had received antibiotic treatment...

A 50-year-old man was admitted with fever and chill sensation 6 months ago. Transthoracic echocardiography (TTE) showed left and right coronary cusp prolapses and a thickened tissue of the aortic curtain. Congestive heart failure due to active infective aortic valve endocarditis was diagnosed, and he underwent aortic valve replacement. The aortic annulus was reconstructed using a glutaraldehydetreated autologous pericardium. Six months after surgery, TTE showed severe aortic regurgitation and saccular change in the aortic annulus...

Introduction/objectives autoantibodies to types I and IV collagen have been described in rheumatic fever and infective endocarditis. We tried to elucidate if an autoimmune response against collagens I and IV exists, associated with heart valve disease in systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). A cohort of 172 patients with SLE (n = 79), primary APS (PAPS, n = 83), and secondary APS (n = 10) were assessed for valvulopathy by transthoracic echocardiograms. Autoantibodies to types I and IV collagen were assessed in patients and 50 controls, setting autoantibody positivity at two standard deviations above the mean antibody level of controls...

Tricuspid stenosis (TS) is an uncommon complication of ventricular pacemaker implantation. Mechanisms described by the literature are ventricular inflow obstruction by tricuspid vegetations (endocarditis) or multiple pacemaker leads and fibrosis secondary to mechanical trauma, accounting for perforation or laceration of the TV leaflets, or adherence between redundant loops and valve tissue. We present the case of iatrogenic tricuspid stenosis, observed in a 77-year-old man. Extrinsic tricuspid valve stenosis was detected by transthoracic echocardiography...

BACKGROUND: Bacterial endocarditis is a recognised disease in humans and animals. In humans, infection with Coxiella burnetii can cause endocarditis, but this has not been investigated thoroughly in animals. Endocarditis in cattle is a common post-mortem finding in abattoirs and studies have identified Trueperella pyogenes as a major cause. Despite exposure of cattle to C. burnetii, the significance of this particular bacterium for development and progression of endocarditis has not been studied in detail...

Crucial to the management of staphylococcal bacteremia is an accurate evaluation of associated endocarditis, which has both therapeutic and prognostic implications. Because the clinical presentation of endocarditis can be nonspecific, the judicious use of echocardiography is important in distinguishing patients at high risk of developing endocarditis. In the presence of high-risk clinical features, an early transesophageal echocardiogram is warranted without prior transthoracic echocardiography. The purpose of this study was to investigate the clinical risk factors for staphylococcal infective endocarditis that might warrant earlier transesophageal echocardiography and to describe the incidence of endocarditis in cases of methicillin-resistant and methicillin-sensitive Staphylococcus aureus bacteremia...

BACKGROUND: Infective endocarditis (IE) is a severe disease requiring lengthy hospitalisation. Little is known about patients' recovery after IE. The aims of this study in IE patients were; (i) to describe mortality, readmission, self-reported health and rehabilitation up to 1year post-discharge, (ii) to examine associations between self-reported health and readmission, and (iii) to investigate predictors of readmission and mortality. METHODS: All adults treated for IE in Denmark, January-June 2011 (N=347), were followed in registers...

Infective endocarditis of the tricuspid valve (TVE) occurs predominantly in selected groups of patients including intravenous drug users (IVDUs). The most often cultured pathogen in IVDUs is Staphylococcus aureus. Eikenella corrodens, normally existing as a commensal in the mouth and the upper respiratory tract, is identified as an etiologic pathogen of endocarditis very rarely. The authors describe a case of a 27-year-old male with a past history of staphylococcal TVE readmitted to hospital after 5 months due to progression of right-sided heart failure...

PURPOSE OF THE REVIEW: Infective endocarditis (IE) is a serious disease with significant morbidity and mortality. Valve surgery is fundamental in the standard of care of selected IE patients. Indeed, valve surgery can be a lifesaving procedure in critically ill endocarditis patients. Our goal from this review is to discuss the indications of surgery in IE population and international cardiac societies' guideline recommendations. RECENT FINDINGS: Though IE is an uncommon disease, its incidence is noted to be on rise in some parts of the world, and the disease is expected to continue to be a major health problem...

Tetralogy of Fallot (TOF) is one of the most common forms of cyanotic congenital heart disease usually managed by serial surgical repairs. The repaired prosthetic valve or conduit is susceptible to life-threatening infection. FDG-PET is an effective alternative to evaluate the source of infection when other examinations are inconclusive. We report an unusual case of an infected pulmonary artery conduit after TOF repair although the echocardiogram was negative for vegetation, which was later confirmed by surgery and pathology...

INTRODUCTION: Optimal timing of surgical treatment for infective endocarditis (IE) complicated by intracranial hemorrhage remains controversial. PRESENTATION OF CASE: A 43-year-old man with IE received appropriate antibiotic therapy but had recurrence of cerebral infarction and intracranial hemorrhage (ICH). Emergency valve surgery was performed 2days after ICH onset because of heart failure and recurrence of cerebral complications. Postoperatively, he showed no neurologic symptoms; neuroimaging showed no enlargement of ICH...
