High incidence of sudden death late after anterior LV-aneurysm repair.

Objectives: Sudden death due to ventricular arrhythmias occurs frequently among patients with dilated cardiomyopathy and congestive heart failure (CHF). In patients with left ventricular (LV) aneurysms, LV-aneurysm repair (LVAR) reduces LV-size and ameliorates symptoms of CHF, but the incidence of late sudden death is unknown, especially after LVAR without concomitant anti-arrhythmic therapy.

Methods: Between June 1993 and June 1999, 147 patients (70% males; 62+/-9 years) with CHF (median: NYHA III) due to anterior LV-aneurysms underwent LVAR.
