Contemporary strategies for repeat ablation of atrial fibrillation: a European Heart Rhythm Association survey
Authors' conclusion
Real-world strategies for repeat AF ablation show significant variability. 3D mapping and CF-guided RF ablation are commonly utilized. Re-PVI and substrate-based ablation are the predominant approaches.
