| Abstract: | Echocardiograms were obtained from unanesthetized cats positioned in left lateral recumbency. Information regarding chamber wall thickness, lumen dimensions, valve motion, and indices of contractility was obtained. In three cases, echocardiographic manifestations typical of cardiac dilatation, cardiac hypertrophy, and pericardial effusion were recorded. Unlike thoracic radiographs, which portray pulmonary features as well as a cardiac silhouette, the echocardiogram provided an opportunity to measure each component comprising the cardiac silhouette--namely, the pericardial sac, cardiac musculature, and the cardiac chambers. |
