Nonpharmacologic Treatment of Supraventricular and Ventricular Tachyarrhythmias: A Review of 249 Consecutive Patients

Abstract

Incapacitating or life-threatening tachyarrhythmias were treated nonpharmacologically in 249 patients from 1982 to 199 1. Among 92 patients surgically treated for supraventricular tachycardia the cure rate was 93% and the complication rate 12%. Radiofrequency catheter ablation gave an equal cure rate in 5 1 patients, but with no major complications or mortality. Direct-current catheter ablation of the His bundle was successful in 96% of 27 patients with drugrefractory atrial fibrillation or other supraventricular tachyarrhythmias. Among 64 patients undergoing surgery for ventricular tachycardia/ventricular fibrillation, the perioperative mortality was 9 %, estimated 5-year survival 69% and estimated 5-year freedom from the preoperative arrhythmias 72 Yo. Of 18 patients treated with implantable cardioverter defibrillator, three (1 8 O/ o) died of heart failure during followup. Nonpharmacologic treatment of tachyarrhythmias is concluded to be effective and often definitively curative. The safety-risk ratio is improving as new treatment modalities are developed.
