Additional Ablation of Complex Fractionated Atrial Electrograms (CFAEs) After Pulmonary Vein Isolation (PVAI) in Patients With Atrial Fibrillation: A Meta-Analysis

Study Questions:

Does ablation of complex fractionated atrial electrograms (CFAEs) improve the efficacy of radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) when performed after pulmonary vein antrum isolation (PVAI)?
