Atrial fibrillation (AF) leads to detrimental changes in the left atrial (LA) and left atrial appendage’s (LAA) hemodynamics and volumes. When indicated, AF ablation is used to reduce AF burden. We recruited 17 post-ablation patients, 10 of whom had no documented AF recurrences. 4D flow MRI was acquired, immediately before and 6-12months after ablation, and quantified for LA and LAA stasis, volume, and peak velocities. Our findings support the notion that restoration of sinus rhythm corrects the deleterious changes of AF.
