Abstract

The aim of this retrospective study was to evaluate the success rate and the satisfaction of patients after radiofrequency ablation of supraventricular tachycardias. 94 consecutive patients, 62 with AV-node-reentry-tachycardia (AVNRT) and 32 with AV-reentry-tachycardia (AVRT) were included. Success rate of ablation was 98% for AVNRT and 94% for AVRT. Recurrence rates were 11% and 9% respectively. The interval between the first tachycardia and ablation was very long (mean 17 +/- 14 years) and prior drug therapy was successful in only 13% of patients. Minor complications were observed in 12% and only one major complication (AV-fistula) was treated surgically. No pacemaker had to be implanted due to a complete AV-block. After ablation 96% of patients were "strongly satisfied" or "satisfied" with the procedure and their relief of symptoms. In addition limitations in all investigated activities (everyday-life, work, sport, hiking, travelling, sexual activity) were significantly reduced (all p < 0.005).
