TL;DR: The utility of delayed-enhancement magnetic resonance imaging (DE-MRI) in detecting abnormal atrial tissue before radiofrequency ablation and in predicting procedural outcome is reported and may provide insight into the progress of the disease.

TL;DR: LA wall fibrosis by delayed-enhancement MRI is inversely related to LA strain and strain rate, and these are related to the AF burden.

TL;DR: There seems to be a correlation between the extent of left atrial wall injury and short-term procedural outcome and noninvasive MRI methods that allow for the detection and quantification of LA wall scarring after RF ablation in patients with AF.

TL;DR: The preliminary, multicenter results suggest DE- MRI-based detection of LA fibrosis is independently associated with prior history of strokes, and it is proposed that the amount of DE-MRI-determinedLA fibrosis could represent a marker for stroke and a possible therapeutic target with potential applicability for clinical treatment for patients with AF.

TL;DR: The degree of LA structural remodeling as detected using DE-MRI is independent of AF type and associated comorbidities, and selecting appropriate treatment candidates based on the quality and quantity of atrial fibrosis using De-MRI would improve procedural outcome and avoid unnecessary intervention.
