Pulmonary vein stenosis after second-generation cryoballoon ablation for atrial fibrillation
نویسندگان
چکیده
Pulmonary vein isolation (PVI) is the cornerstone of catheter ablation for atrial fibrillation (AF), especially in paroxysmal 1 AF patients. In addition to a radiofrequency ablation catheter, a cryoballoon has been proven as an effective technology in PVI for AF. Recently several randomized trials have shown that cryoballoon ablation was noninferior to radiofrequency ablation with respect to efficacy for the treatment of patients with drug-refractory paroxysmal AF, and there was no significant difference between the 2 methods with regard to overall safety. Pulmonary vein (PV) stenosis was one of the major complications after PVI.

Introduction Cryoballoon ablation with pulmonary vein isolation is a novel technology for the treatment of atrial fibrillation. Its efficacy was established after the introduction of the second-generation cryoballoon (CB-2). Cryothermal energy is known to be safer than other energy sources. However, some reports have shown an increasing rate of phrenic nerve palsy and elevated myocardial biomar...

The cryoballoon was invented to achieve circumferential pulmonary vein isolation more efficiently to compliment the shortcomings of point-by-point ablation by radiofrequency ablation (RFA). Its efficacy and safety were shown to be comparable to those of RFA, and the clinical outcomes have improved with the second-generation cryoballoon. The basic biophysics, implemental techniques, procedural r...
