摘要: Objective This study was performed to observe the effect of radiofrequency catheter ablation (RFCA) in patients with paroxysmal atrial fibrillation (PAF) and explore risk factors for late recurrence (LRAF) after a single RFCA session. Methods In this retrospective study, 243 PAF underwent were followed up regularly. Results At median follow-up 37 months procedure, 60.5% maintained sinus rhythm (SR), at 42 multiple procedures, 74.9% SR. The statistically significant LRAF session left diameter (LAD), inferior pulmonary vein superior-inferior (LIPV SID), PV number variation, circumferential isolation (CPVI) combined additional ablation, early (ERAF). best cut-off value LAD 35.5 mm. Conclusions During 3-year follow-up, about 70% procedure associated LAD, LIPV SID, CPVI ERAF.
