Point-by-point radiofrequency catheter ablation strategies for atrial fibrillation focus on improving lesion quality and optimizing the detection of acute pulmonary vein reconnection.
This review summarizes strategies to improve the durability of pulmonary vein isolation during point-by-point radiofrequency ablation for paroxysmal atrial fibrillation.
May enhance PVI durability via optimized lesion quality and reconnection detection; leaves open confirmation in randomized trials.
Pulmonary vein isolation by point-by-point radiofrequency catheter ablation constitutes the cornerstone of catheter ablation strategies for the treatment of atrial fibrillation. However, despite advances in pulmonary vein isolation ablation strategies, long-term success rates after ablation remain suboptimal, which highlights the need to develop techniques to achieve more durable lesions. Strategies proposed to improve the durability of pulmonary vein isolation can be divided into two groups: Those addressed to improving the quality of the lesion and those that optimize the detection of acute PV reconnection during the ablation procedure. This manuscript reviews the role and potential benefits of these techniques according to current clinical evidence.
