Closure of a paravalvular communication originating from the pseudoaneurysm of the mitral-aortic intervalvular fibrosa following prosthetic valve infective endocarditis

Abstract

Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (PMAF) is a rare but potentially life-threatening event, which is usually caused by infective endocarditis and surgical trauma following cardiac surgery. Although there is a likelihood of an asymptomatic course, the most frequent clinical manifestations are signs of infection from active endocarditis, chest pain, heart failure, and cerebrovascular events; and the common dreaded complications of PMAF were reported as fistulas into the left atrium and aorta (20%) and coronary artery compression (10%) (1). Here, we present a case of successful percutaneous closure of a paravalvular communication originating from PMAF into the left ventricle.
