The objectives of this study were to describe and compare the clinical characteristics and outcomes of patients with definite and possible infective endocarditis (IE) involving prosthetic heart valve, and to identify prognostic factors for long-term mortality, using data from an unselected cohort of consecutive patients. We studied data from 133 consecutive patients with IE involving prosthetic heart valve seen in an academic institution between 1990 and 2012. Patients were classified according to the modified Duke criteria for IE: patients with possible IE (n = 47, 35%) and patients with definite IE (n = 86, 65%)...

Candida Endocarditis (CE) is a deadly disease. It is of paramount importance to assess risk factors for acquisition of both Candida native (NVE) and prosthetic (PVE) valve endocarditis and relate clinical features and treatment strategies with the outcome of the disease. Areas covered: We searched the literature using the Pubmed database. Cases of CE from the Italian Study on Endocarditis (SEI) were also included. Overall, 140 cases of CE were analyzed. Patients with a history of abdominal surgery and antibiotic exposure had higher probability of developing NVE than PVE...

Prosthetic valve endocarditis (PVE) is a serious infection with potentially fatal consequences. Early detection is crucial for successful management and outcome. The diagnosis of PVE is challenging and is based on the Duke criteria (DC) in which echocardiography plays a crucial role. However, transthoracic and transoesophageal echocardiography have less diagnostic value in PVE compared to native valve endocarditis. Combined computed tomography and fluorodeoxyglucose positron emission is a new technique providing improved diagnostic accuracy in PVE...

Infective endocarditis (IE) is a severe disease with high mortality and morbidity. Prosthetic valve endocarditis is a life-threatening complication which can occur in less than 10% of patients with valve prosthesis. A fungal etiology of IE is rare and accounts for only 2-4% of all case of endocarditis, but is associated with a higher mortality and morbidity. Herein is reported the first case of fungal endocarditis of aortic valve prosthesis due to Aspergillus oryzae in a 67-year-old caucasian man who nine years previously underwent mitral and aortic valve replacement with mechanical prostheses, and tricuspid annuloplasty for acute IE due to Enterococcus spp...

BACKGROUND: The presence of more than one bacterial agent is relatively rare in infective endocarditis, although more common in prosthetic cases. Molecular diagnosis from a removed heart tissue is considered a quick and effective way to diagnose fastidious or intracellular agents. CASE PRESENTATION: Here we describe the case of postpartum polymicrobial prosthetic valve endocarditis in a young woman. Sneathia sanguinegens and Mycoplasma hominis were simultaneously detected from the heart valve sample using broad range 16S rRNA polymerase chain reaction (PCR) followed by sequencing while culture remained negative...

Prosthetic valve endocarditis is a very grave and often terminal disease. Surgical valve replacement remains the cornerstone treatment for this disease. However, it is often contraindicated. Herein, we describe the implantation under direct visualization of a self-expandable transcatheter heart valve in a prohibitive surgical risk patient with homograft aortic valve endocarditis.

BACKGROUND: Since 2013, over 100 cases of Mycobacterium chimaera prosthetic valve endocarditis and disseminated disease were notified in Europe and the USA, linked to contaminated heater-cooler units (HCUs) used during cardiac surgery. We did a molecular epidemiological investigation to establish the source of these patients' disease. METHODS: We included 24 M chimaera isolates from 21 cardiac surgery-related patients in Switzerland, Germany, the Netherlands, and the UK, 218 M chimaera isolates from various types of HCUs in hospitals, from LivaNova (formerly Sorin; London, UK) and Maquet (Rastatt, Germany) brand HCU production sites, and unrelated environmental sources and patients, as well as eight Mycobacterium intracellulare isolates...

Right-sided infective endocarditis (RSIE) is less common than left-sided infective endocarditis (IE), encompassing only 5-10% of cases of IE. Ninety percent of RSIE involves the tricuspid valve (TV). Given the relatively small numbers of TVIE cases operated on at most institutions, the purpose of this review is to highlight and discuss the current understanding of IE involving the TV. RSIE and TVIE are strongly associated with intravenous drug use (IVDU), although pacemaker leads, defibrillator leads and vascular access for dialysis are also major risk factors...

Fungal endocarditis (FE) is a rare and fatal disease. The contemporary in-hospital and long-term surgical outcomes of FE have not been adequately evaluated. This study describes our experience with the surgical management of FE.Eight FE patients who underwent surgery in our center from January 2004 to November 2016 were included in this study. Seven had fungal prosthetic valve endocarditis (PVE) and one fungal native valve endocarditis (NVE). The Bentall operation, Cabrol operation, and mitral valve replacement were performed in 4, 3, and 1 patient, respectively...

OBJECTIVE: Adults with congenital heart disease (CHD) are at increased risk of infective endocarditis (IE). Women with CHD have a lower IE risk, potentially due to gender-related differences in dental care. We aimed to assess self-reported dental hygiene measures in adults with CHD, and to identify factors associated with good oral hygiene. METHODS AND RESULTS: Descriptive study includes 187 adults with CHD at increased risk of IE. The patients' IE knowledge was assessed using an adapted version of the Leuven Knowledge Questionnaire for CHD...

REVIEW
Zubair A Khan, Steven M Hollenberg
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...

REVIEW
John F Trujillo, Steven M Hollenberg
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...
