Routine Clinical Atrial Flutter Ablations

Video Transcription

Video Summary

The speaker describes interventional MRI for cardiac ablation, beginning with typical atrial flutter as an easy, anatomically defined target. He explains how MR-guided procedures reduce fluoroscopy exposure for patients and staff while offering real-time 3D anatomy, substrate visualization, and lesion assessment. He reviews early clinical experience showing comparable procedure times to conventional EP labs and highlights post-ablation imaging with T2 mapping and LGE. Looking ahead, he discusses MR-guided ventricular arrhythmia ablation, scar-channel targeting, and virtual heart “digital twin” models that could simulate VT inducibility and help define the minimal effective ablation strategy.
