RESUMO
New onset regional wall motion abnormality (RWMA) following coronary artery bypass grafting adversely affects the patient outcome. Early detection and addressing the cause of RWMA improves overall morbidity and mortality of the patient. We report a rare case of early myocardial ischemia detected by intraoperative transesophageal echocardiography due to mechanical compression of a vein graft by a pericardial drain tube.

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.
