Cows with dilated (congestive) cardiomyopathy (case 1), chronic large abscesses of the pericardium (case 2) and bovine leukemia with cardiac involvement (case 3) were examined, using M-mode and two-dimensional echocardiography. Case 1 was characterized by dilatation of four cardiac chambers with poor ventricular function. Case 2 revealed the existence of large pericardial abscesses accompanied by cardiac atrophy echocardiographically. The echocardiographic features of case 3 were symmetrically thickened ventricular walls due to leukemic infiltration of the myocardium. Besides, an abnormal mitral closure on the M-mode echocardiogram, indicative of an elevated left ventricular end-diastolic pressure was added to cases 1 and 2. Echocardiographic findings corresponded, to a certain degree, to pathological findings.
