Abstract
Previous reports of radiofrequency ablation for the management of symptomatic patients with longstanding persistent atrial fibrillation (LSP-AF) of more than 2 years have suggested a poor outcome and consequently these patients are often denied an ablative strategy. Ablation for LSP-AF ranges from PVI combined with DC cardioversion to more aggressive approaches aimed at addressing additional substrate with either linear lesions and/or targeting of complex fractionated atrial electrograms (CFE). We describe a novel stepwise ablation strategy for the management of LSP-AF.
