Abstract
Objective: To evaluate the efficacy and safety of the radiofrequency ablation of persistent atrial fibrillation (AF) after a 6-month follow-up. Subject and method: A prospective study of 40 patients with persistent AF who underwent catheter ablation using a three-dimensional (3D) system at the Vietnam Heart Institute, Bach Mai Hospital. Result: The mean age of patients was 54.25 ± 12.54. The procedure time was 256.25 ± 48.61 minus, the irradiation time was 29.55 ± 14.29 minus, and the number of ablation points was 132.77 ± 53.79 points. The ablation time was 64.10 ± 24.76 minus, and the number of cardioversion shocks was 1.17 ± 1.1 times. No severe complications occurred during and after the procedure, and there and 2D echocardiography before the procedure and during the follow-up period. The success rates of maintaining sinus rhythm (SR) after 6 months, isolating the pulmonary vein alone, and the additional ablation group were 60.7%, 55%, and 75%, respectively. The successfully maintained SR group had no other AF symptoms [European Heart Rhythm Association (EHRA) class I], and patients with AF recurrence showed symptoms (EHRA class IIb). Conclusion: AF radiofrequency ablation is a new method with a success rate of 60.7% after a 6-month follow-up. Patients with successful ablation showed symptom improvement. The ablation procedure is safe, with a low rate of severe complications.
