ABSTRACT
A double-outlet left ventricle (DOLV) is a congenital cardiac anomaly that rarely is encountered. This case report demonstrates the echocardiographic features of DOLV in the form of the pulmonary artery arising completely from the left ventricle with D-looped ventricles, especially when evaluated by intraoperative transesophageal echocardiography (TEE), along with the correlation of characteristic features with cardiac computerized tomography. The features pertinent to the differentiation of DOLV from double-outlet right ventricle and congenitally corrected transposition of the great arteries by echocardiography have been described. To the authors' knowledge, this was the first report of intraoperative TEE in the case of DOLV. In addition, the use of intraoperative echocardiography to rule out coronary compression as a cause for post-repair ventricular tachycardia, by use of TEE to rule out ventricular dysfunction and regional wall motion abnormalities, as well as epicardial echocardiography to demonstrate normal coronary blood flow, has been reported.
