What are the incidence, prevention, and management of complications associated with radiofrequency catheter ablation for atrial fibrillation?
Radiofrequency catheter ablation for atrial fibrillation carries a 3.9-6% risk of significant complications, emphasizing the importance of understanding their prevention and management.
Complication rates warrant ongoing vigilance in AF ablation; leaves open optimal prevention strategies pending prospective data.
Radiofrequency catheter ablation is widely performed as an effective treatment for recurrent, drug-resistant atrial fibrillation (AF). Recently, various types of ablation strategies, such as extensive encircling pulmonary vein (PV) isolation, linear ablation and complex fractionated electrogram-guided ablation, have been used to achieve a high efficacy for all types of AF. However, several complications (thromboembolic events, PV stenosis and atrio-esophageal fistula etc) with an incidence of 3.9-6%, have been reported. It is important to understand the incidence, prevention and management of complications in order to develop safe ablation strategies.
