Ca-535-04 pulmonary vein isolation for atrial fibrillation using true high power short duration vs. cryo-ablation

Pulmonary vein isolation (PVI) in patients (pts) with paroxysmal (PAF) and persistent (persAF) atrial fibrillation is equally achievable and effective using a cryoballoon (Cryo) or radiofrequency (RF) catheter ablation (CA). The newly introduced high RF power short duration ablation (HPSD) technique has shown promising results in clinical trials. However, data comparing HPSD- to Cryo-PVI is sparse.
