Abstract

Left atrial dissection (LatD), defined as the forced separation of the left atrial (LA) wall layers by blood, is a rare and severe complication of cardiac surgery. It is most frequently associated with atrioventricular junction injuries. We report a case of infected LatD after coronary artery bypass graft, mitral valve replacement, aortic valve replacement and ascending aortic root replacement. The patient was presented with septicemia and disseminated intravascular coagulation. To the best of our knowledge, this is the first case report of LA dissecting flap concomitant with attached infective vegetations identified by transesophageal echocardiography.
