目的:分析冠状动脉先天性变异的冠状动脉造影表现,探讨冠状动脉造影的诊断价值。方法:2003年1月～2007年12月在武汉钢铁公司总医院行冠状动脉造影的患者900例,对其结果进行回顾性分析。结果:共检出67例冠状动脉先天性变异,检出率为7.44%。其中检出冠状动脉瘘9例,检出率为1.00%,并以冠状动脉-右心室瘘最为多见。12例为冠状动脉起源和分布异常,占1.33%,并以右冠状动脉的先天性变异为多见。检出冠状动脉心肌桥(壁冠状动脉)46例,检出率为5.11%,并以左前降支心肌桥多见。结论:冠状动脉先天性变异的临床症状和体征多不典型或缺如,冠状动脉造影是确诊各种冠状动脉先天性变异的重要手段。
Objective: To analyze the coronary angiography of congenital variations of coronary arteries and to explore the diagnostic value of coronary angiography. Methods: From January 2003 to December 2007, 900 patients underwent coronary angiography at Wuhan Iron and Steel Company General Hospital. The results were retrospectively analyzed. Results: A total of 67 cases of congenital coronary artery were detected, the detection rate was 7.44%. Among them, 9 cases were detected coronary fistula, the detection rate was 1.00%, and the most common coronary - right ventricular fistula. 12 cases of abnormalities in the origin and distribution of coronary arteries, accounting for 1.33%, and to the right coronary artery congenital mutations are more common. 46 cases of coronary artery myocardial bridge (wall coronary artery) were detected, the detection rate was 5.11%, and the left anterior descending myocardial bridge more common. Conclusion: The clinical symptoms and signs of congenital variations of coronary arteries are atypical or absent. Coronary angiography is an important method to diagnose congenital variations of various coronary arteries.
