Abstract

Non-iatrogenic left atrial wall dissection is a rare lesion defined as a gap from the mitral valve annulus to the interatrial septum or wall of the left atrium. We report the case of a 57-year-old man with symptoms of acute cardiac and renal failure. Trans-esophageal echocardiography and computed tomography showed significant mitral valve regurgitation and dissection of the posterior wall of the left atrium. On the basis of detailed trans-esophageal echocardiography, the patient underwent mitral valve replacement with closure of the dissection orifice, which appears to be the appropriate therapeutic strategy in cases of spontaneous left atrial wall dissection.

Keywords: echocardiography; heart surgery; left atrial wall dissection; mitral valve regurgitation; mitral valve replacement.
