Right atrioventricular atresia with a ventricular septal defect, a rare congenital cardiac anomaly of either animals or man, was diagnosed in a one week old Arabian foal. The foal had been weak and cyanotic since birth, sometimes becoming dyspneic when stressed. Necropsy revealed a dilated and hypertrophied left ventricle with the right ventricle being small. The right atrioventricular valve was absent. The right and left ventricles communicated via a septal defect which was located immediately adjacent to the aortic valve.
右房室闭锁合并室间隔缺损，这是一种在动物或人类中均罕见的先天性心脏畸形，在一匹一周大的阿拉伯马驹中被诊断出来。这匹马驹自出生以来就体弱且发绀，在应激时有时会出现呼吸困难。尸检显示左心室扩张且肥厚，右心室较小。右房室瓣缺失。左右心室通过紧邻主动脉瓣的室间隔缺损相通。
