Left Ventricular Free‐Wall Rupture Occurring During Programmed Ventricular Stimulation in a Patient With Recent Myocardial Infarction

ANDRESS, J.D., et al.: Left Ventricular Free‐Wall Rupture Occurring During Programmed Ventricular Stimulation in a Patient With Recent Myocardial Infarction. In this report we describe a patient who died during programmed ventricular stimulation due to a rupture of the left ventricular free wall at the site of a recent myocardial infarction. The patient was a 75‐year‐old male who presented with an extensive anterior wall myocardial infarction complicated by sustained ventricular tachycardia occurring 8 days after admission. Cardiac catheterization revealed total occlusion of left anterior descending coronary artery and an anteroapical aneurysm. The patient died due to electromechanical dissociation during electrophysiological testing 11 days after myocardial infarction. Postmortem examination showed a rupture of the left ventricular free wall at the site of the myocardial infarction and distant from the site of catheter placement. It is suggested that caution be taken in choosing patients for electrophysiological studies who have had recent large myocardial infarctions with ventricular aneurysm.
