title: Hypoplasia of the left ventricle in four ruminants.
abstract: 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.
