Coronary artery anomalies are found in 0.2% to 1.3% of patients undergoing coronary angiography and 0.3% of an autopsy series. We aimed to estimate the frequency of coronary artery anomalies in our patient population.
The data were collected retrospectively by analyzing the angiographic data of 12 457 consecutive adult patients undergoing coronary angiography between September 2002 and October 2007.
Coronary artery anomalies were found in 112 patients (0.9% incidence), 100 patients (89.3%) had origin and distribution anomalies, and 12 patients (10.7%) had coronary artery fistulae. Their mean age was 52 ± 8 years (range, 22-79 y). Separate origins of left anterior descending and left circumflex coronary artery from the left sinus of Valsalva was the most common anomaly (63.4%). The right coronary artery rising from the left coronary sinus of Valsalva was found in 10 (8.9%) patients. Anomalous origin of the left circumflex coronary artery from the right sinus of Valsalva was seen in 10 (8.9%) patients. The left main coronary artery from the right coronary sinus of Valsalva was found in 1 (0.89%) patient while an isolated single coronary artery was seen in 2 (1.78%) patients.
The incidence and the pattern of coronary artery anomalies in our patient population were almost identical with previous studies. Cardiologists should be aware of the coronary anomalies which may be associated with potentially serious cardiac events, because recognition of these coronary anomalies is mandatory in order to prescribe appropriate therapy.
在接受冠状动脉造影的患者中，冠状动脉异常的发生率为 0.2%至 1.3%，在尸检系列中为 0.3%。我们旨在评估我们患者人群中冠状动脉异常的频率。
通过分析 2002 年 9 月至 2007 年 10 月期间连续 12457 例成年患者的冠状动脉造影数据，回顾性收集数据。
在 112 例患者（发生率为 0.9%）中发现冠状动脉异常，100 例（89.3%）存在起源和分布异常，12 例（10.7%）存在冠状动脉瘘。他们的平均年龄为 52±8 岁（范围，22-79 岁）。左前降支和左回旋支冠状动脉分别发自左冠状动脉窦的起源异常是最常见的异常（63.4%）。10 例（8.9%）患者右冠状动脉发自左冠状动脉窦。10 例（8.9%）患者左回旋支冠状动脉发自右冠状动脉窦。1 例（0.89%）患者左主干发自右冠状动脉窦，2 例（1.78%）患者存在孤立性单支冠状动脉。
我们患者人群中冠状动脉异常的发生率和模式与之前的研究几乎相同。心脏病专家应该意识到可能与潜在严重心脏事件相关的冠状动脉异常，因为识别这些冠状动脉异常是规定适当治疗的必要条件。
