摘　　要：目的合并室间隔缺损、左室流出道狭窄的复杂型大动脉转位的尚无理想的手术治疗方式,双动脉根部调转术是近年来这一领域的新尝试。使用超声心动图技术评价该手术重建后早期的心脏结构、血流及功能状况。方法对74例双动脉根部调转术后患者于出院前行常规的全面经胸超声心动图检查。结果所有病例左室流出道形态正常,流速(1.1±0.2)m/s(0.7～1.5 m/s);右室流出道流速在(1.0±0.3)m/s(0.8～1.5 m/s)。所有病例主动脉瓣血流正常;所有病例肺动脉瓣前向血流正常,中度以上肺动脉瓣反流2例。所有病例双心室收缩功能正常范围。结论双动脉根部调转术可以重建良好的双心室流出道及半月瓣功能,并保持完好的双心室功能,术后早期效果良好。Objective To assess the function and hemodynamic performance of the reconstructed hearts after our newly developed double root translocation procedures（DRT） for patients with transposition of the great arteries, ven- tricular septal defect, and pulmonary stenosis by echocardiography. Methods Transthoracic echocardiography was performed in 74 postoperative patients underwent DRT procedure. Results The morphology of left ventricular out- flow track was normal in all cases. The flow velocities were normal in both ventricular outflow tracks. There was no aortic regurgitation in all cases; Only 2 cases were detected with moderate or severe pulmonary regurgitation. And biventricular functions were normal in all cases. Conclusions DRT procedure restored normal intracardiac anatomy with excellent early hemodynamic and ventricular performance. It is a true anatomic and physiological repair.
