Summary

Data from a cohort study of the DECAAF trial demonstrate that late gadolinium enhancement magnetic resonance imaging is a useful technique for identifying left atrial scarring following ablation of atrial fibrillation. Of 3 different ablation techniques, cryoablation produces more scarring than does point-by-point and multipolar RF ablation. Neither overall scar nor complete pulmonary vein encirclement was a significant predictor of arrhythmia recurrence.
