Abstract

The coronary arteries of 50 goats were studied by means of angiography and dissection. The results were as follows: The right coronary artery (RCA) and left coronary artery (LCA) arose from the right and left aortic sinuses respectively. At the beginning, the average external diameter of RCA (2.98 +/- 1.02 mm) was smaller than that of LCA (3.42 +/- 0.74 mm). An independent inter ventricular septal artery (in 94%) supplied the upper two-thirds of the inter ventricular septum. The arterial distributive types were divided into three: The LCA was dominant in 96%, symmetrical in 4%, RCA dominant in 0%. Sixty two percent of the S-A node arteries arose from the RCA, 28% from LCA, 10% from both RCA and LCA. All the A-V node arteries originated from the LCA.

摘要

通过血管造影和解剖对50只山羊的冠状动脉进行了研究。结果如下：右冠状动脉（RCA）和左冠状动脉（LCA）分别起自右和左主动脉窦。起始处，RCA的平均外径（2.98±1.02毫米）小于LCA（3.42±0.74毫米）。一条独立的室间隔动脉（94%）供应室间隔上三分之二。动脉分布类型分为三种：LCA占优势的96%，对称的4%，RCA占优势的0%。62%的窦房结动脉起自RCA，28%起自LCA，10%起自RCA和LCA两者。所有房室结动脉均起自LCA。
