The Impact

Introduction: Atrial fibrillation (AF) is associated with diffuse myocardial fibrosis as quantified by cardiac magnetic resonance (CMR) using T1 mapping methods. Radiofrequency catheter ablation (RFCA) is evolving, and the role in rhythm control may be ideal for reversing left ventricular (LV) remodeling. Hypothesis: We aimed to study the impact of RFCA on diffuse myocardial fibrosis in AF patients. Methods: We retrospectively collected data from consecutive AF patients who underwent RFCA with modified Look-Locker Inversion recovery T1 mapping sequences on pre/post procedural CMR at 3.0-Tesla. Precontrast T1 relaxation time of the mid-LV short-axis view was used as an index of diffuse LV fibrosis. Primary outcome was the change in diffuse LV fibrosis after RFCA. Results: A total of 11 patients (mean age 67 years, 72% male, 67% paroxysmal AF) were enrolled. Median AF duration was 24.6 months [Interquartile range (IQR): 13.3-45.3)] and median CHA2DS2-VASc was 2 [IQR: 1-3]. Post RFCA CMR was obtained 99.5±18.1 days after the RFCA procedure. Mean precontrast T1 time was significantly lower after RFCA (1182ms vs 1158ms; p=0.0157). Conclusions: Based on our preliminary results, RFCA in AF reduces diffuse myocardial fibrosis and may play a role in reverse LV remodeling.
