New heart ablation technique faces off against gold standard in AFib trial

This study compares two minimally invasive procedures to treat a common heart rhythm problem called paroxysmal atrial fibrillation. About 210 adults who have not had this treatment before will be randomly assigned to receive either the standard cryoballoon method or a newer pulsed field ablation. The goal is to see if the newer technique is just as effective at preventing irregular heartbeats from returning within a year, while possibly being safer.
