Long-term follow-up of a second generation implantatible cardioverter defillator for the treatment of life-threatening ventricular tachyarrhythmias

Abstract

The second generation impl antabl e cardioverter defibrillator (ICD: Ventak P Model 1600) was implanted to 6 patients (pts) with life-threatening ventricular tachycardia(VT)/ventricular fibrillation(VF). However, one patient with severe left ventricular dysfunction died due to LOS 8 months postoperatively, 5 pts were alive. Five pts had inappropriate shocks during sinus tachyarrhythmia, paroxismal supraventricular tachycardia or after termination of VT/VF. Four out of 6 pts needed generator exchange at mean 3.2 years after operation. This clinical experience indicated that Ventak P 1600 implantation for the life-threatening VT/VF is effective and safe in preventing sudden cardiac death.
