左冠状动脉异常起源于肺动脉患者手术疗效的超声评价

Therapeutic evaluation by echocardiography after surgical repair of anomalous origin of the left coronary artery from the pulmonary artery

目的探讨超声对左冠状动脉（冠脉）异常起源于肺动脉患者手术疗效的评估价值。方法对2000-2007年间本院施行手术矫治的6例左冠脉异常起源于肺动脉患者（3例肺动脉内隧道术，3例左冠脉旁路移植术）术后进行超声检查，并与术前超声结果相对照。结果6例患者术后短期内冠脉系统血流动力学基本恢复，二尖瓣反流程度减轻，心功能良好。除1例出现吻合口轻度梗阻和少量内隧道瘘外，其余5例重建血管通畅。结论经胸超声能准确评估重建冠脉的通畅情况、手术并发症、心脏形态和功能以及二尖瓣反流的转归。

Objective To explore the role of echocardiography in the therapeutic evaluation after surgical repair of anomalous origin of the left coronary artery from the pulmonary artery（ALCAPA）. Methods Six patients with ALCAPA underwent surgery from 2000 to 2007,including 3 intrapulmonary tunnel procedures and 3 left coronary artery bypass graft procedures. Post-operative echocardiography was given in every case and the characteristics were compared with the pre-operative results. Results In all cases, the mainly coronary haemodynamics recovered rapidly with decreased severity of mitral regurgitation and excellent cardiac function. Five patients had smooth rebuilded vessels but 1 patient had mild anastomotic block and slight intrapulmonary tunnel leakage. Conclusions Transthoracic echocardiography can evaluate the rebuilded coronary artery, possible complication,cardiac morphous and function and the severity of mitral regurgitation accurately.
