Echocardiography is a useful noninvasive test for evaluating patients with suspected heart failure and enlarged cardiac silhouette. This test can obtain the dimensions and wall thickness of all four cardiac chambers and can evaluate left ventricular function. The test results are reproducible, and in many instances the etiology of heart failure can be determined.
