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.
双出口左心室(DOLV)是一种罕见的先天性心脏异常。本病例报告展示了DOLV的超声心动图特征,表现为肺动脉完全起源于左心室且心室呈D袢,特别是通过术中经食管超声心动图(TEE)评估时,同时还展示了其特征与心脏计算机断层扫描的相关性。文中描述了通过超声心动图将DOLV与右心室双出口及先天性矫正型大动脉转位相鉴别的相关特征。据作者所知,这是首例关于DOLV术中TEE的报告。此外,还报告了利用术中超声心动图排除冠状动脉受压作为修复后室性心动过速的原因,通过TEE排除心室功能障碍和局部室壁运动异常,以及通过心外膜超声心动图显示正常冠状动脉血流的情况。
