Why the study?
The study was conducted to assess index lesion durability, reablation strategy, and outcomes in FIRE AND ICE trial patients undergoing a reablation procedure for recurrent paroxysmal AF.
Does initial ablation with cryoballoon compared to radiofrequency current reduce the number of reconnected pulmonary veins at repeat ablation in patients with recurrent atrial fibrillation?
Does initial ablation with cryoballoon compared to radiofrequency current reduce the number of reconnected pulmonary veins at repeat ablation in patients with recurrent atrial fibrillation?
Initial pulmonary vein isolation with cryoballoon results in fewer reconnected pulmonary veins at the time of repeat ablation compared to radiofrequency ablation.
No takes yet. Share an insight, caveat, or question.
Cryoballoon linked to fewer PV reconnections at redo ablation; leaves open whether this affects outcomes or should guide initial strategy.
