Aneurysmectomy for Control of Ventricular and Supraventricular Tachyarrhythmias in Patients with Post-infarction or Traumatic Myocardial Aneurysms.

Abstract
Few patients have been described in whom refractory ventricular tachycardia was controlled by removal of myocardial aneurysms; most of these were postinfarction aneurysms. Of 33 consecutive patients with myocardial aneurysms diagnosed by angiography at the University of lowa Hospital, eight had resistant or recurrent tachyarrhythmias. Aneurysmectomy was performed on six of the eight patients. Three patients were operated on because of refractory tachyarrhythmia alone; the other three were operated on because of congestive heart failure besides the arrhythmia. Four patients survived surgery, with no recurrence of the arrhythmia, for a follow-up period of 5 to 24 months. Of these, one
