Two cases of isolated anomalous origin of the left circumflex coronary artery from the right Valsalva sinus are described. In contrast with all the cases reported in the literature, both our female patients had typical angina; in one case, moreover, in coincidence with the precordial pain there were significant alterations of the repolarization, also caused by stress testing with the bicycle ergometer. On the basis of these findings, the authors believe that in patients with this anomaly the angina might be produced through a sharp decrease in the circumflex coronary artery blood flow correlated with caliber changes of the aorta.
本文描述了两例左旋支冠状动脉单独起源于右冠状动脉窦的病例。与文献报道的所有病例不同，我们的两名女性患者均有典型心绞痛；此外，在其中一例中，与心前区疼痛同时出现的是复极的显著改变，这也是由自行车测力计进行的应激试验所诱发的。基于这些发现，作者认为，对于患有这种异常的患者，心绞痛可能是由于左旋支冠状动脉血流急剧减少并与主动脉管径变化相关所致。
