Subacute Rupture of the Free Left Ventricular Wall Following Acute Myocardial Infarction

ABSTRACT. In previously published cases of subacute or sealed postinfarction rupture of the free left ventricular wall, the patients presented a clinical picture of sudden shock and tamponade. Our patient, a 64-year-old man, suffered renewed chest pain on the fourth postinfarction day and went into cardiogenic shock, which was pharmacologically reversible. There were no bed-side signs of tamponade and the ECG showed the pattern of acute pericarditis, both features in contrast to previously reported cases in the literature. Echocardiography demonstrated localized fluid in the pericardial sac and a puncture revealed non-coagulating blood. The patient was successfully operated on. At surgery a small rupture sealed by blood clots was demonstrated in the infarcted inferior wall of the left ventricle.
