摘要
The present study aimed to evaluate the safety and efficacy of an optimized single transseptal puncture technique and contact force sensing atrial fibrillation (AF) radiofrequency catheter ablation (RFCA) strategy within a clinical setting. Fast anatomic mapping and contact force sensing ablation was applied to patients with paroxysmal AF (PAF) ablation between September 2014 and December 2016 using a single trans‑septal sheath. Pulmonary vein isolation (PVI) and linear ablation were performed in PAF individually with a 10‑20 g contact force with minimal fluoroscopy. Stimulation with 10 mA outputs on the lesions without capture was used as endpoint. A total of 419 consecutive patients who underwent first‑time RFCA were enrolled in the current study, and acute PVI was achieved in all patients. The average procedure time was 74.5±9.7 min, with an average ablation time of 27.3±7.8 min. The average fluoroscopy time was 4.7±3.3 min and the average radiation dose was 24.3±25.2 mGy. At a mean follow‑up time of 14.5 ± 4.1 months, sinus rhythm was maintained at 85.0%. Cardiac tamponade occurred in one case. The results indicated that this simplified technique was a simple, safe and effective approach for PAF ablation therapy.
