Infective Endocarditis Complicated by Pseudoaneurysm of the Mitral-Aortic Intervalvular Fibrosa Without Valvular Involvement

Abstract

A pseudoaneurysm of the mitral-aortic intervalvular fibrosa (p-MAIVF) can be a catastrophic sequela of untreated active infective endocarditis. We describe a case of infective endocarditis complicated by p-MAIVF without valvular involvement. This case highlights the importance of this rare clinical entity and of transesophageal echocardiography in reaching a diagnosis. (Level of Difficulty: Beginner.)
