Current ablation strategies for persistent and long-standing persistent atrial fibrillation

Area of Science:

• Cardiology
• Electrophysiology

Background:

• Atrial fibrillation (AF) increases mortality risk.
• Restoring sinus rhythm is crucial, preferably without antiarrhythmic drugs.
• Catheter ablation is a standard treatment for symptomatic, drug-refractory AF.

Purpose of the Study:

• To review the efficacy of current catheter ablation strategies for persistent and long-standing persistent AF.
• To highlight the complexities and varying effectiveness of different ablation approaches.

Main Methods:

• Review of current ablation strategies for persistent and long-standing AF.
• Focus on pulmonary vein antral isolation, electrogram-based ablation, and linear lesions.
• Assessment of stepwise ablation approaches.

Main Results:

• Pulmonary vein isolation is the cornerstone of AF ablation.
• Strategies for persistent and long-standing persistent AF are more complex.
• No single strategy is uniformly effective for these AF types.

Conclusions:

• Current ablation strategies for persistent and long-standing persistent AF are diverse and complex.
• Further research is needed to optimize efficacy for these patient groups.
