BackgroundCatheter ablation is an established rhythm control therapy for atrial fibrillation. However, as the extent of ablation increases, the risk of complications may also rise. This has motivated strategies that achieve pulmonary vein isolation with less lesion creation while preserving safety and effectiveness. MethodsIn this prospective, multicenter, randomized non-inferiority trial, 130 patients undergoing first-time ablation for paroxysmal or non-paroxysmal atrial fibrillation were assi...
