A ruptured mitral valve aneurysm as complication of a bicuspid aortic valve endocarditis

Abstract

We present a case of a ruptured mitral valve (MV) aneurysm as a complication of a bicuspid aortic valve (BAV) endocarditis. It is about a young 35-year-old man, admitted to Cardiology Unit because of unexpected heart failure picture. We found a BAV endocarditis complicated by anterior MV-anterior leaflet aneurysm formation and subsequent severe MV regurgitation caused by aneurysm perforation. It was a particular and rare situation characterized by an infection of anterior mitral leaflet secondary to an infected regurgitant jet of a primary aortic infective endocarditis due to a BAV. A resulting aneurysm formation on the atrial side of the mitral anterior leaflet leads later to mitral perforation. In this article, we review the more relevant medical literature on this topic.

A Perforated Mitral Valve Aneurysm: A Rare but Serious Complication of Aortic Valve Endocarditis Resulting From a Regurgitant Jet Lesion

“…A recent review of about 30 published cases of MVA associated with IE showed that surgery is performed in about 75% of cases [ 8 ]. In some cases, with a favorable clinical presentation, rapid control of infection with antibiotics and the absence of other guideline-recommended reasons for surgery, conservative treatment can be initiated under close clinical and echocardiographic monitoring [ 19 ].…”
