Suksaranjit P, et al. - Researchers looked at the clinical significance of left atrial appendage (LAA)-structural remodeling (SRM) in atrial fibrillation (AF) patients who underwent ablation therapy. They quantified the extent of the LAA-LGE (late gadolinium enhancement) in a total of 74 AF patients who underwent catheter ablation therapy within 14 days following LGE-MRI scan. Patients were followed for arrhythmia recurrence after the ablation procedure. The study population comprised of 68% male, with a mean age of 72 years. An association of the extent of LAA-SRM, identified by LGE-MRI, with arrhythmia recurrence after AF ablation was noted.
