Successful surgical management of left ventricular free wall rupture in the course of myocardial infarction

The case of a 49-year-old patient is described who presented with cardiogenic shock and electrocardiographic signs of an inferolateral Q-wave infarction, and who received systemic lysis with anisoylated plasminogen streptokinase activator complex (Eminase). After coronary angiography had revealed only peripheral occlusion of a posterolateral branch of the left circumflex coronary artery, a pericardial effusion surrounding both right and left ventricular cavity was identified by echocardiography and was successfully drained via an inferior pericardiotomy with an immediate rise of blood pressure. Upon thoracotomy myocardial rupture was detected in the infarct area and was closed with mattress sutures. A total of 39 cases of successful surgical repair of myocardial free wall rupture reported in the literature is discussed. The mean age of patients was 59.6 +/- 1.3 years. Posterior and anterolateral infarctions were the preferred locations of myocardial rupture. Rupture occurred with a mean delay of 5.0 +/- 1.0 days after the onset of clinical infarct signs. Among patients saved by surgical means were 33 males and 6 females.
