The recent few years has seen the emerging role of Cardiac MR Imaging in Atrial Fibrillation. In particular, delayed enhancement imaging following catheter ablation has allowed for areas within the left atrium following tissue injury to be visualized. There is a good correlation between scar quantification and clinical outcome. In this study we performed a randomized control clinical study using CMR to assess a novel robotic catheter ablating navjgation system and correlated CMR data to clinical outcomes.
