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.

(A) 3D reconstructing of magnetic resonance pulmonary veins angiography (PA view) demonstrating the site of entry of each pulmonary vein. (B) 2D delayed contrast hyperenhancement demonstrating no fibrosis of left atrium tissue.

Mentions: AF ablation is a challenging procedure. Appropriate patient selection is the most critical step to ensure safe and successful AF ablation procedure. Integrating data on left atrial anatomy, size, shape, and degree of fibrosis provided by MRI into pre-procedural planning is crucial (Figure 3).
