Double outlet right ventricle, a rare congenital heart anomaly of either animals or man, was diagnosed in a three day old Brangus heifer. The clinical course was brief, consisting of terminal recumbency, dyspnea and cyanosis. Upon necropsy, the heart was enlarged as a result of marked dilatation of the right atrium and the right ventricle. The aorta arose from the right ventricle while the left ventricle ended blindly near the ventral cusp of the left atrioventricular valve. The wall of the left ventricle was thickened, reducing the ventricular lumen.
右心室双出口是一种罕见的动物或人类先天性心脏异常，在一头3日龄的勃莱牛小母牛中被诊断出来。临床病程短暂，包括末期躺卧、呼吸困难和发绀。尸检时，由于右心房和右心室明显扩张，心脏增大。主动脉起源于右心室，而左心室在左房室瓣腹侧瓣尖附近盲端终止。左心室壁增厚，使心室腔缩小。
