Iatrogenic Mitral Valve Perforation following CABG and Aortic Valve Replacement: A Rare Complication detected by Post-bypass Transesophageal Echocardiography

Abstract

ABSTRACT Iatrogenic mitral valve perforation following aortic valve replacement is a rare complication. We present a case of anterior mitral leaflet perforation following coronary artery bypass grafting (CABG) and aortic valve replacement detected by intraoperative transesophageal echocardiography (TEE). A 57-year-old male patient with preoperative diagnosis of coronary artery disease, sclerodegenerative aortic valve with severe aortic stenosis and mild central mitral regurgitation (MR) underwent CABG and aortic valve replacement. A post bypass TEE in midesophageal long axis view showed an additional MR jet across the body of the anterior mitral leaflet. We present intraoperative TEE images with a discussion on role of TEE in detection of mitral valve perforation and surgical decision making.
