Contrast-enhanced echocardiography aids evaluation of rare but serious post-MI subepicardial aneurysms.
Case Report
Echocardiography, particularly with contrast enhancement, is valuable for the early diagnosis and evaluation of subepicardial aneurysms following myocardial infarction.
May support contrast echocardiography for post-MI subepicardial aneurysm assessment; leaves open prospective validation before wider use.
Subepicardial aneurysms (SEA) are an infrequent and serious form of subacute cardiac rupture complicating myocardial infarction. An early diagnosis and surgical repair may be life saving. SEA comprise an abrupt interruption of the myocardium, with a narrow neck and thin wall containing only the epicardium. It may progress to fatal cardiorrhexis. We describe the echocardiographic evolution of this type of cardiac rupture and the contribution of contrast-enhanced echocardiography. A possible pathophysiological mechanism is proposed.

Roldán et al. (2009) conducted a case report in Subepicardial aneurysm complicating myocardial infarction. Contrast-enhanced echocardiography was evaluated. Contrast-enhanced echocardiography aids in the evaluation and understanding of the evolution of subepicardial aneurysms, an infrequent but serious complication of myocardial infarction.
