Bottom Line: Atrial fibrillation ablation is a complex and challenging procedure.The DECAAF study (Delayed-Enhancement MRI Determinant of Successful Radiofrequency Catheter Ablation of Atrial Fibrillation) showed that atrial tissue fibrosis, as estimated by delayed enhancement magnetic resonance imaging, was independently associated with recurrent arrhythmia post atrial fibrillation ablation.Integrating the data provided by magnetic resonance imaging into the pre-procedural planning is crucial.

ABSTRACT
Atrial fibrillation ablation is a complex and challenging procedure. Appropriate patient selection is the most critical step to ensure safe and successful atrial fibrillation ablation procedure. The DECAAF study (Delayed-Enhancement MRI Determinant of Successful Radiofrequency Catheter Ablation of Atrial Fibrillation) showed that atrial tissue fibrosis, as estimated by delayed enhancement magnetic resonance imaging, was independently associated with recurrent arrhythmia post atrial fibrillation ablation. Magnetic resonance imaging also detected left atrial volume and shape. Integrating the data provided by magnetic resonance imaging into the pre-procedural planning is crucial.

shows four stages of left atrial tissue fibrosis based on 3D delayed enhancement magnetic resonance imaging scans. Normal left atrial wall is displayed in blue, fibrotic changes are in green and white, the pulmonary veins and mitral valve are shown in gray. Stages 1 through 4 show increasing amounts of fibrosis as a percentage of the total left atrial wall volume. (N. Marrouche et al. JAMA. 2014; 311 (5): 498–506).

Normal left atrial wall is displayed in blue, fibrotic changes are in green and white, the pulmonary veins and mitral valve are shown in gray. Stages 1 through 4 show increasing amounts of fibrosis as a percentage of the total left atrial wall volume. (N. Marrouche et al. JAMA. 2014; 311 (5): 498–506).

Mentions: In total, 260 patients with atrial fibrillation, including 65% with paroxysmal atrial fibrillation, were included in the study. All patients underwent a pre-ablation MRI up to 30 days before the procedure and 90 days following the ablation. Based on the degree of atrial remodeling/fibrosis, patients were classified into four groups: stage 1 ( < 10% fibrosis), stage 2 (>10% to < 20% fibrosis), stage 3 (>20% to < 30% fibrosis), and stage 4 (>30% fibrosis) (Figure 1).
