Echocardiography.
Diagnostic ultrasound permits the clinician to image the beating heart, quantitate cardiac dimensions, identify specific congenital and acquired cardiac lesions, and estimate the degree of cardiac compensation and muscle failure that accompanies a specific lesion. The M-mode (motion) echocardiogram and two-dimensional echocardiogram are complementary studies that have proved useful for identification of cardiac septal defects, endocarditis, pericardial effusion, intracardiac shunting, cardiomegaly, and heart muscle failure. Appreciation of the technique and basic knowledge of the types of information that can be obtained from echocardiography are necessary to appropriately refer horses for these studies.
