[Transesophageal echocardiography diagnosis of perforation of the mitral valve secondary to infective endocarditis]. / Diagnóstico por ecocardiografía transesofágica de perforación de la válvula mitral secundaria a endocarditis infecciosa.

We report on a patient with infective endocarditis and severe mitral regurgitation secondary to perforation in the base of the posterior mitral leaflet. Transthoracic echocardiography was inconclusive. Only transesophageal echocardiography could confirm the presence of vegetations, their characteristics and the existence of valvular perforation. We also review the literature on the contribution of transesophageal echocardiography to the diagnosis of infective endocarditis and its complications.
