Elevated fibrosis burden as assessed by MRI predicts cryoballoon ablation failure

Late‐gadolinium enhancement magnetic resonance (LGE‐MRI) imaging is increasingly used in management of atrial fibrillation (AFib) patients. Here, we assess the usefulness of LGE‐MRI‐based fibrosis quantification to predict arrhythmia recurrence in patients undergoing cryoballoon ablation. Our secondary goal was to compare two widely used fibrosis quantification methods.
