原发性冠状动脉先天畸形是能以孤立病变出现的一类畸形,它可以不伴有其他先天性心脏病变。与血液动力学无关的畸形主要指冠状动脉的异常主动脉起源和分布,在成人冠状动脉造影中的发现率略小于1％,在儿童中可与右位或左位型大动脉转位、法乐氏四联症、右心室双流出道和单心室并存。有血液动力学意义者以心肌灌注异常为其特点,主要可分为四类:(1)冠状动脉瘘;(2)左冠状动脉起源于肺动脉;(3)先天性冠状动脉
Primary congenital anomalies of coronary artery is a type of deformity that can appear as isolated lesions, it may not be associated with other congenital heart disease. Hemodynamic unrelated deformity mainly refers to the origin and distribution of abnormal coronary aorta in adult coronary angiography was found in slightly less than 1% in children with right or left type of aortic transposition, Tetralogy of Fallot, right ventricular outflow and single ventricle coexist. There are hemodynamic significance of myocardial perfusion abnormalities as its characteristics, can be divided into four categories: (1) coronary fistula; (2) the left coronary artery originated in the pulmonary artery; (3) congenital coronary artery
