Lessons from individualized cryoballoon sizing. Is there a role for the small balloon?

摘要

Background: Cryoablation for paroxysmal atrial fibrillation (PAF) is well established. The single-big balloon strategy has been preferred for pulmonary vein isolation (PVI) using the second generation cryoballoon (CBG2). Individual PV-morphologies raise the question if an individualized anatomic approach using the 23-mm or 28-mm CB is reasonable.
