Abstract:
Segmental pulmonary vein isolation (SPVI) and circumferential pulmonary vein isolation (CPVI) are the two main approaches to radiofrequency ablation in patients with atrial fibrillation (AF). The aim of this retrospective study was to investigate the safety level and patient outcome of both approaches. The overall freedom from symptoms was 73% and 25% after CPVI and SPVI, respectively. Our study concludes that CPVI is an effective treatment of highly symptomatic and drug-resistant AF and when used in laboratories by experienced electrophysiologists has a promising and reproducible outcome ratio and safety level.
