冠状动脉起源异常的检出率与冠状动脉狭窄

目的　评价国人冠状动脉(冠脉)起源异常的冠脉造影检出率,并探讨其与冠脉狭窄之间的关系。方法　回顾性分析2001年1月至2004年6月在我院接受选择性冠脉造影的患者,观察并记录冠脉起源异常的检出频度和类型,以及合并冠脉狭窄的情况。结果　4094例患者中,共检出冠脉起源异常者32例,检出率为0 78%,其中右冠脉异常起源最为多见,占总数的65 6%;合并冠脉狭窄者共11例(占34 3% ), 其中仅5例(占15 6% )累及起源异常的冠脉,且无1例冠脉狭窄单独累及起源异常的冠脉。结论　国人冠脉起源异常的检出率与国外文献报道结果相似,其中以右冠脉起源异常最为多见,冠脉起源异常与冠脉狭窄不具有相关性。

Frequency of the anomalous coronary origin in the Chinese population with coronary artery stenosis

Objective 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 Methods 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 Results 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 Conclusions 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
