Technical - Interventional CMR-Discussion

Video Transcription

Video Summary

The session concluded with practical advice for starting MRI-guided electrophysiology and catheter programs. Thomas recommended beginning with simpler arrhythmias like atrial flutter to build experience, then progressing to more complex substrate-based atrial and ventricular cases. Josh noted that launching a program can be less costly than expected, but requires careful planning, safety preparation, and persistence through hospital bureaucracy.<br /><br />Panelists also discussed real-time lesion visualization, guidewire use, and ECG monitoring challenges during MRI procedures. Participants described current guidewire strategies using susceptibility markers and noted limitations in simultaneous imaging. For defibrillation systems, experts highlighted the difficulty of obtaining reliable ECGs in the scanner, especially at 3T, but said 1.5T is more manageable. They emphasized the importance of rapid defibrillation capability and said commercial MR-conditional defibrillator solutions may be nearing regulatory submission. The session ended on an optimistic note about future growth in MRI-guided EP.
