PVI:

General periprocedural guidance includes target activated clotting time (ACT) ≥350, catheter exchange ≤2, >10s spacing of consecutive applications, and minimization of number of PF applications per the recommended procedures below:

For each pulmonary vein, a concentric ring of applications will be created using 12 (6 ostial and 6 antral) applications In case of visual gaps, additional 8 applications will be added

PWI:

Concentric overlapping ablations will be placed throughout the posterior wall deliberately. The catheter will be rotated once between a pair of applications; briefly, rotation is performed such that, post-rotation, the splines are situated midway between the splines' pre- rotation positions. The number of applications will be at the operator's discretion.

VoM:

VoM alcohol ablation procedure will be conducted before the catheter ablation. VoM will be visualized by coronary sinus venography, cannulated with an angioplasty wire and balloon and 1 cc of 98% ethanol will
