We describe 2 cases in which intraoperative transesophageal echocardiography detected complications related to the proximal coronary arteries during homograft aortic valve and root replacement. In both cases, cardiopulmonary bypass could not be discontinued despite the use of large doses of inotropic drugs. Transesophageal echocardiography demonstrated aliasing on color flow mapping in the left main coronary artery in 1 case and proximal right coronary artery in the other, along with severely depressed left ventricular anterior wall and right ventricular function, respectively. Coronary artery bypass grafting was performed in both cases, and the outcome was successful.
