Hypoplasia of the left ventricle in four ruminants.
Two different congenital malformations of the heart were seen in two calves and two ewe lambs. In all these malformations the left ventricle was more or less hypoplastic; it was small with a narrow lumen and a thick wall. In one malformation the aorta began as a cul-de-sac above the left ventricle; in the other, the aorta arose from the right ventricle, to the right of the supraventricular crest.
