摘　　要：目的:研究冠状动脉畸形及其临床意义。方法:在460例冠状动脉的解剖中,发现7例冠状动脉异常,并对此动脉开口移位和冠状动静脉瘘进行解剖与观察。结果:在7例中,5例冠状动脉开口移位,经动脉圆锥前、主动脉后或主动脉与肺动脉干之间横过心底,到达其分布区。单一(右)冠状动脉Ⅱ型或一冠状动脉发自对侧主动脉窦提供解释:此冠状动脉畸形的青年,可在运动时或运动后猝死。2例冠状动静脉瘘,显示冠状动脉和肺动脉干与左室之间,存在毛细血管前吻合。结论:冠状动脉畸形在临床实践中有其意义,其发生有它的胚胎学基础。Objective： To investigate the coronary artery malformation and its clinical significance. Methods： In 460 specimens of hearts, 7 cases of coronary artery malformation were discovered and observed. Careful dissections were made to reveal the structures surrounding abnormal coronary artery, Results： In the 5 of 7 cases, the coronary arteries traversed the base of the heart passing through arterial cone anteriorly or aorta posteriorly, or between the aorta and the pulmonary trunk before reaching its distribution area. A single （right） coroanry artery of Ⅱ type and a coronary artery originating from the contralateral aortic sinus offered an explanation for sudden death, which usually occurred during or immediately after exercise, in young individuals. In the other two cases of the coronary arteriovenous fistulas, it is defined as a direct precapillary anastomosis between a majar coronary artery and the pulmonary trunk or the left ventricle. Conclusions： The morphologic and topographic anatomy of the coronary artery malformation is significant for clinical practice. Its development is based on its embryological foundation.
