Abstract
- Laser- Versus CryoBalloon for PVI Introduction Balloon catheters have been developed to facilitate pulmonary vein isolation (PVI) in patients with paroxysmal atrial fibrillation (PAF). We sought to compare the safety and efficacy of the cryoballoon (CB) and the laserballoon (LB) in a pilot study. Methods and Results One hundred and forty patients with drug-refractory PAF were prospectively allocated in a 1:1 fashion to undergo a PVI procedure with the 28 mm CB or the LB and were followed for 12 months using 3-day Holter ECG recording. The primary efficacy endpoint was a documented AF recurrence ≥30 seconds between 90 and 365 days after the index ablation. In total, 269 of 270 PVs (99.6%) and 270 of 273 PVs (98.9%) were acutely isolated in the CB and LB group, respectively. Mean procedural time was 136 ± 30 minutes for the CB group and 144 ± 33 minutes for the LB group (P = 0.13). Mean fluoroscopy time was longer in the CB group (21 ± 9 minutes vs 15 ± 6 minutes; P
