Echocardiograms were performed on three patients with ventricular septal
rupture complicating myocardial infarction. The pulmonary artery mean
pressure was 30 mm Hg or more in all three patients. The size of the
ventricular septal defect, determined at operation or autopsy, was 2 cm or
greater in each patient. The salient echocardiographic abnormality was
dilatation of the right ventricle. The direction of septal motion was
normal in all the patients. The left atrial diameter was slightly increased
in one patient and was normal in the other two. In one patient, and unusual
pattern of mitral valve motion was seen. Complete closure of the reopening
of the valve. This pattern was suggestive of increased blood flow through
the mitral valve. Although some of these findings are nosspecific, the
combination of echocardiographic findings may provide useful clues to the
diagnosis of septal perforation.
