摘　　要：Cardiac magnetic resonance(CMR)imaging could enable major advantages when guiding in real-time cardiac electrophysiology procedures offering high-resolu-tion anatomy,arrhythmia substrate,and ablation lesion visualization in the absence of ionizing radiation.Over the last decade,technologies and platforms for performing electrophysiology procedures in a CMR environment have been developed.However,performing procedures outside the conventional fluoro-scopic laboratory posed technical,practical and safety concerns.The development of magnetic resonance imaging compatible ablation systems,the recording of high-quality electrograms despite significant electromagnetic interference and reliable methods for catheter visualization and lesion assessment are the main limiting factors.The first human reports,in order to establish a procedural workflow,have rationally focused on the relatively simple typical atrial flutter ablation and have shown that CMR-guided cavotricuspid isthmus ablation represents a valid alternative to conventional ablation.Potential expansion to other more complex arrhythmias,especially ventricular tachycardia and atrial fibrillation,would be of essential impact,taking into consideration the widespread use of substrate-based strategies.Importantly,all limitations need to be solved before application of CMR-guided ablation in a broad clinical setting.
