The diagnosis, angiographic evaluation and surgical treatment by aortocoronary vein bypass are described in a 3(1/2)-year-old girl with anomalous origin of the left coronary artery from the pulmonary artery. The anomaly had resulted in cardiac dilatation, diminished left ventricular contractility, an aneurysm of the left ventricular free wall and mitral regurgitation.At the postoperative cardiac catheterization the graft was demonstrated to be patent, but a significant proportion of the flow to the left coronary artery was derived from anastomotic connections with the right coronary artery. The most striking evidence of improvement was obtained from the left ventricular volume studies which showed that the end systoiic volume had decreased from 85 to 49 ml./m.(2) with an increase in ejection fraction from 0.39 to 0.62, suggesting enhanced left ventricular contractility after surgery.The patient continues to do well and is free from symptoms.
本文描述了一名3岁半患有左冠状动脉起源于肺动脉异常的女孩，其诊断、血管造影评估以及通过主动脉冠状动脉静脉搭桥进行的手术治疗。该异常导致心脏扩张、左心室收缩力减弱、左心室游离壁动脉瘤和二尖瓣反流。术后心导管检查显示移植血管通畅，但流向左冠状动脉的大部分血流来自与右冠状动脉的吻合连接。左心室容积研究提供了最显著的改善证据，结果显示收缩末期容积从85降至49ml/m²，射血分数从0.39增至0.62，提示术后左心室收缩力增强。患者术后情况持续良好，无症状。
