Lesion Formation With Pulsed Field Versus Cryobaloon Ablation as Assessed by Cardiac Magnetic Resoncance

Source: ClinicalTrials.gov · Last updated 7 Apr 2026

Brief summary (registry, in English)

This randomised study will compare pulsed field ablation and cryoballoon ablation with respect to ablation lesion quality as assessed by late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) at 3 months post-ablation. Patients scheduled for first-time AF ablation will be randomised in a 2:1 fashion to receive PVI-only, either by pulsed field ablation (Farapulse Pulsed Field Ablation System, Boston Scientific) or cryoballoon ablation (Medtronic Cryoballoon Ablation System).
