[Automatic implantable defibrillator and antiarrhythmic surgery in ischemic cardiopathies. Apropos of 53 cases].
The automatic implantable defibrillator (AID) and antiarrhythmic surgery are the two therapeutic options after failure of catheter ablation and/or antiarrhythmic therapy for sustained ventricular tachycardia (VT) or ventricular fibrillation (VF) in patients with coronary artery disease. The authors undertook retrospective study of the characteristics of two groups of patients treated between November 31st 1987 et December 31st 1993 either by AID (28 men and 4 women with an average age of: 56.1 +/- 11.2 years) or by surgery (19 men and 2 women with an average age of: 60.6 +/- 6.8 years). The "surgical" patients differed from "defibrillator" patients in the fewer number of cardiac arrests, a higher proportion of sustained monomorphic VT, better tolerated sustained monomorphic VT (rarely syncopal), fewer early post-infarction arrythmias (< or = 8 weeks), more anterior wall infarction and a higher proportion of aneuvrysms. The perioperative mortality was 6.2% in the "defibrillator" group and nil in the "surgical" group (p = NS). At 2 years, the sudden death rate in the "defibrillator" and "surgical" groups was 7.5% and 0% respectively and total cardiac mortality was 17% and 20% respectively (p = NS). The authors conclude that perioperative mortality and the sudden death rate at 2 years are relatively low in the two groups. However, the total cardiac mortality remains high, largely related to perioperative death and secondary cardiac failure. Nevertheless, compared with defibrillator patients and with identical average ejection fractions, there was no extra mortality due to cardiac failure after antiarrhythmic surgery.
