“…Early aggressive antibiotic therapy is sometimes sufficient and there so no need to reoperate the patient [5]. Causes of late artificial valve endocarditis are similar to those in early endocarditis, but are more prone to less virulent microbes like Staphylococcus epidermidis [6]. The most common cause between intravenous drug addicts is Staphylococcus aureus which causes 70% of endocarditis cases [7], [8].…”

BACKGROUND: Prosthetic mechanical valve endocarditis (PVE) can be manifested as early PVE (acquired perioperatively) and late PVE (resulting from infections unrelated to the valve operation). Causes of both are similar but are late PVE are more prone to less virulent microbes. PVE resulting with paravalvular abscess is confirmed through echocardiography (transthoracic or transesophageal), it results with a high mortality rate especially if it is not early recognized. The aim of article was to present a patient with heart failure symptoms caused by PVE. CASE PRESENTATION: Male patient, 44 years old, was admitted because of dyspnea and swelling of lower extremities. The patient is a long-standing heroin addict who had aortic valve replacement done 8 years ago due to endocarditis. The implanted valve was a mechanical aortic valve – Edwards MIRA bi-leaflet valve No 32 (Edwards Lifesciences; Irvine, California). He also was already diagnosed with hepatitis C years before. In multiple occasions were hospitalized on the Department of cardiology due to signs and symptoms of heart failure. On transthoracic echocardiography, dilatation of all heart chambers was found. The left ventricular systolic function was moderately reduced with an ejection fraction of left ventricle of 42% according to Simpson with restrictive filling pattern. Hypoechoic mass along the right side of the mechanical aortic valve was noted measuring 3.57 × 1.03 cm. CONCLUSION: Paravalvular abscess of mechanical heart valves is a very serious complication with a high mortality rate. It is essential to recognize this type of pathology as early as possible, so aggressive parenteral antibiotic therapy could be started, while in many cases, surgical reoperation is needed.

Implantable cardiac electronic device (ICED) infections are a major cause of morbidity and mortality. Understanding the pathogenesis of these infections is important in their prevention and management. We hypothesized that ICED infections could be classified as 'early' or 'late', based on differences in microbiological cause within or beyond 1 year of implantation, respectively. A comprehensive review of the literature was undertaken to test this hypothesis. Prosthetic valve endocarditis cases were included for comparison. Articles were included if the time from device implantation to infection, definite evidence of infection (pocket/bacteraemia/endocarditis) and a positive microbiological diagnosis were included. There were no statistically significant differences in microbiology to support a 1 year cut-off between early and late ICED infection. Staphylococcus aureus and coagulase-negative staphylococci were the predominant causes of ICED infection both within and beyond 1 year of ICED implantation. To further assess the microbiological causes of ICEDs and their implications for pathogenesis a large-scale multicentre study is required.

Late Prosthetic Valve Endocarditis Caused by Staphylococcus hemolyticus

Abstract: We describe a case of late PVE in a 78-year-old man that was caused by Stapylococcus hemolyticus and occurred 5 years after aortic valve replacement. This is the first reported case of PVE due to this organism.
