Summary

Pulmonary vein isolation is the cornerstone of atrial fibrillation ablation. During radiofrequency applications, the lesion is created by resistive and conductive heating of the tissue. The ablation catheters and generators have undergone impressive technical developments to reach homogenous and durable lesion creation. The aim of the atrial fibrillation catheter ablation is to achieve transmural, wide, durable lesions. The most effective way to achieve this goal is to use higher radiofrequency energy for shorter duration. Multiple clinical studies have proven the safety and efficacy of this technique.
