Diagnosis and treatment of subacute free wall ventricular rupture after infarction.
Ventricular rupture is usually a sudden, lethal complication after acute myocardial infarction (MI). Some patients, however, may survive several hours after ventricular rupture, and there is time for surgical repair if the diagnosis is made quickly. In 1980 and 1981, 7 patients underwent operation for ventricular rupture at our institution. Bedside hemodynamic studies with a Swan-Ganz catheter confirmed the diagnosis of pericardial tamponade. Urgent operation with cardiopulmonary bypass was performed. Control of hemorrhage was obtained by covering the ventricular tear and the surrounding infarcted myocardium with a wide Teflon patch. Four patients are alive and well 2, 3, 4, and 10 months after operation. Clinically, free wall ventricular rupture should be suspected when any patient recovering from an acute MI experiences chest pain and cardiovascular collapse. Bedside hemodynamic monitoring will confirm the diagnosis of cardiac tamponade, and urgent operation will save some of these patients.
