title: [Observation and measurement of coronary arteries of goat].
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.
