To estimate the frequency of anomalous coronary origin with angiography in the Chinese population and evaluate the correlation between anomalous coronary origin and development of coronary atherosclerotic stenosis.
All of the patients who underwent diagnostic coronary angiography from January 2001 to June 2004 were retrospectively reviewed. Those with anomalous origin of the coronary arteries were selected for further assessment and any significant stenosis in one or more coronary arteries or in a major branch was recorded.
Among the 4094 patients, 32 (0.78%) had anomalies of coronary origin. Right coronary artery was the most common anomalous vessel, being involved in 21 (65.6%) patients. It originated from the left sinus of Valsalva in 19 and from the non-coronary aortic sinus in 2 patients. Anomalous left circumflex artery was the second most common anomaly, being seen in 5 (15.6%) patients. Anomalous left main coronary artery from the right sinus of Valsalva and anomalous left coronary artery from pulmonary artery were seen in 3 patients, respectively. Significant lesions in the anomalous arteries were seen in only 5 (15.6%) patients, much less than the overall incidence of coronary artery lesion in patients with coronary anomalies in this series (34.3%). Moreover, no patient was found that the anomalous vessel was the only one involved in coronary atherosclerotic stenosis.
The incidence of anomalous coronary origin in Chinese population is almost as same as in other races and an anomalous right coronary artery is the most common anomaly. The anomalous coronary artery does not appear to be of any increased risk for development of coronary atherosclerotic stenosis.
评估中国人群中冠状动脉起源异常的血管造影频率，并评价冠状动脉起源异常与冠状动脉粥样硬化狭窄发展之间的相关性。
回顾性分析2001年1月至2004年6月期间所有接受诊断性冠状动脉造影的患者。选择冠状动脉起源异常的患者进行进一步评估，并记录一条或多条冠状动脉或主要分支中的任何显著狭窄情况。
在4094例患者中，32例（0.78%）存在冠状动脉起源异常。右冠状动脉是最常见的异常血管，21例（65.6%）患者受累。其中19例起源于左冠状动脉窦，2例起源于无冠状动脉窦。异常左旋支动脉是第二常见的异常，见于5例（15.6%）患者。分别有3例患者出现起源于右冠状动脉窦的异常左主干冠状动脉和起源于肺动脉的异常左冠状动脉。仅5例（15.6%）患者的异常动脉出现显著病变，远低于本系列冠状动脉异常患者中冠状动脉病变的总体发生率（34.3%）。此外，未发现异常血管是唯一发生冠状动脉粥样硬化狭窄的血管。
中国人群中冠状动脉起源异常的发生率与其他种族几乎相同，异常右冠状动脉是最常见的异常类型。冠状动脉起源异常似乎不会增加冠状动脉粥样硬化狭窄发展的风险。
