The aim of this study is to evaluate LA volume measurements using CMR based angiography before and after left atrial RF ablation therapy as a treatment strategy for atrial fibrillation (AFIB) and see how it correlates with the percentage of scar formed 3 months post ablation. We hypothesize that a greater scar percentage obtained at 3 months post procedure would lead to a greater change in volume of the LA (computed as LA volume measured at different time points, normalized by the pre-ablation LA volume).
