摘要: 运用微机图象分析系统,对国人36例成人心脏进行了观察研究。结果零点处,二尖瓣环至冠状动脉旋支的垂直距离;右优势型平均值为8.01 mm,左优势型平均值为3.89 mm,均衡型平均值为6.21 mm。右优势型心脏的冠状动脉旋支距二尖瓣环最远,左优势型则最近,二者有显著性差异(P<0.01)。临床上二尖瓣手术时,左优势型的冠状动脉旋支较易并发损伤,心脏外科医生应给予注意。

Abstract: The left circumflex coronary artery is predisposed to injury during mitral valve opera-tion. We studied 36 hearts of Chinese adults using CASPER 386 PIP-I024B medical image processing system. The average x of vertical distance between the circumflex coronary artery and the mitral anulus at zero point are summarized as follows: In the hearts of the right dominance, x=8.01mm; in the left dominance, x=3.89 mm;and in the codomi-nance,x=6.21 mm. The distance between the mitral anulus and the circumflex coronary artery was the largest in hearts with right dominance, and the circumflex coronary artery was most proximal to the mitral anulus in hearts with left dominance(P<0.01). The left circumflex coronary artery during mitral operation is more predisposed to injury in the pa-tients with left dominance. The cardiovascular surgeons must pay atention to it.

Key words: circumflex coronary artery, mitral anulus, coronary artery, heart
