To present the clinical and angiographic properties of the left anterior descending artery anomalies.
Coronary artery anomalies are discovered in less than 1% of angiography series. Since the number of angiographies and coronary bypass operations are increasing significantly every day, these anomalies are of clinical importance. However, data about left anterior descending artery anomalies in literature is still scarce.
We reviewed the records of 70,850 patients who had undergone coronary angiographies at 4 different cardiology center from 1999 to 2005 years.
Major congenital coronary anomalies were discovered in 171 of these cases (0,24%). The mean age of these patients was 61 +/- 11 (18-84) years. Ninety nine patients (58%) were male. Left anterior descending artery was involved in 12 patients (0.017%). In nine patients with the anomalous LAD there were concomittant congenital coronary artery anomalies. Concurrent coronary artery anomalies encountered were double left anterior descending artery type 4 (2 cases), double left anterior descending artery type 4 with double right coronary artery (1), double right coronary artery (1), double circumflex artery with anomalous left anterior descending artery (1), circumflex artery from right sinus of Valsalva (1), separate septal perforator and myocardial bridging of posterior descending artery (1), intercoronary communication, and ostial atresia of the left anterior descending artery and anomalous circumflex artery (1).
Our series is the biggest series where relatively sufficient clinical and angiographic information about the LAD anomalies were provided.
阐述左前降支动脉异常的临床及血管造影特征。
冠状动脉异常在血管造影系列检查中发现率低于1%。由于血管造影和冠状动脉搭桥手术的数量每天都在显著增加，这些异常具有临床重要性。然而，文献中关于左前降支动脉异常的数据仍然稀少。
我们回顾了1999年至2005年期间在4个不同心脏病中心接受冠状动脉造影的70850例患者的记录。
在这些病例中发现171例主要先天性冠状动脉异常（0.24%）。这些患者的平均年龄为61±11（18 - 84）岁。99例（58%）为男性。左前降支动脉受累12例（0.017%）。在9例左前降支异常患者中，同时存在先天性冠状动脉异常。同时发现的冠状动脉异常有4型双左前降支动脉（2例）、4型双左前降支动脉合并双右冠状动脉（1例）、双右冠状动脉（1例）、双回旋支动脉合并异常左前降支动脉（1例）、发自瓦尔萨尔瓦右窦的回旋支动脉（1例）、单独的间隔穿支和后降支动脉心肌桥（1例）、冠状动脉间交通以及左前降支动脉开口闭锁合并异常回旋支动脉（1例）。
我们的系列是提供了关于左前降支异常相对充分的临床和血管造影信息的最大系列。
