Iatrogenic aortic regurgitation following primary closure of ventricular septal defect: Role of transesophageal echocardiography.

Iatrogenic valvular regurgitation following cardiac surgery has been reported as a result of leaflet perforation or entrapment. Due to its central location, the aortic valve is one of the most vulnerable structures for iatrogenic injuries. Proper assessment of the aortic valve by transesophageal echocardiography (TEE) should be done after a cardiac surgery in the periaortic area. We hereby report a case of iatrogenic aortic regurgitation which was developed after primary closure of perimembranous ventricular septal defect. It was timely diagnosed by TEE after termination of cardiopulmonary bypass and helped in further management.
