The goal of this review is to provide information about the role that cardiac magnetic resonance imaging (CMR) can play in guiding catheter ablation right from patient selection to creating better lesions to post-ablation follow-up. CMR can provide very important information of the scar and fibrotic substrate in the cardiac tissue. Cardiac substrate information from CMR plays a critical role in ventricular and atrial arrhythmia management. CMR can demonstrate the extent of acute edema and long-term scar formation from catheter ablation. All this information can lead to optimal targeting and lesion creation. Understanding all the different aspects of CMR can provide clinical electrophysiologist with valuable information. This results in better managing arrhythmia patients.
