Bioprosthetic Aortic Valve Infective Endocarditis

Infective endocarditis of the aortic valve usually presents with vegetations attached to the ventricular surface of the valve. Vegetations can be large, pedunculated, and freely mobile, making the risk of embolization high. The author reports a case of bioprosthetic aortic valve endocarditis caused by the rare organism Cardiobacterium hominis with an atypical presentation of the vegetation on the aortic surface .

Infective endocarditis

IE is a fascinating disease that continues to challenge the clinicians. Over the last several decades, there have been marked changes in its presentation. The morbidity and mortality have markedly improved by early diagnosis and prompt treatment using highly effective antibiotic regimens and early valve replacement surgery whenever necessary. Early diagnosis is possible by improvement in blood culture techniques and advances in transthoracic and transesophageal echocardiographic approaches. This article has reviewed the pathogenesis, microbiology, clinical presentation, diagnostic methodology, treatment, and prevention of IE.
