Feasibility and Efficacy of Simultaneous Pulmonary Vein Isolation and Cavotricuspid Isthmus Ablation Using Cryotherapy
Cryotherapy for Simultaneous CTI Ablation and PVI Introduction Pulmonary vein isolation (PVI) and cavotricuspid isthmus (CTI) ablation are often performed as part of the same procedure. In many cases, PVI is performed by cryotherapy and then CTI ablation by radiofrequency (RF) energy. We sought to d...

No complication occurred. All veins were isolated; bidirectional CTI block was demonstrated in all cases where it was attempted, except for 1 patient in the PVI/CTI‐mixed group. Procedure and fluoroscopy duration were significantly shorter in the PVI/CTI‐cryo group (162 ± 34 and 24 ± 5 minutes) than in the PVI/CTI‐mixed group (209 ± 46 minutes, P < 0.001 and 59 ± 28 minutes, P < 0.001). Procedure and fluoroscopy duration in the PVI‐only group (155 ± 32 and 22 ± 8 minutes) were similar to those in the PVI/CTI‐cryo group (P = NS) but significantly shorter than in the PVI/CTI‐mixed group (P < 0.001 for both). Clinical outcomes were similar in all groups. Conclusion When CTI ablation is performed with RF energy after PVI by cryoballoon, it adds significantly to the procedure and fluoroscopy durations; when performed contemporaneously using cryotherapy at both sites, the procedure and fluoroscopy durations are not prolonged.
