Non-invasive Assessment of Tissue Heating During Cardiac Radiofrequency Ablation Using MRI Thermography Running title: Kolandaivelu et al.; MRI Thermography of Cardiac Ablation

MRI-Guided Electrophysiology Intervention*

Catheter ablation is a first-line treatment for many cardiac arrhythmias and is generally performed under X-ray fluoroscopy guidance. However, current techniques for ablating complex arrhythmias such as atrial fibrillation and ventricular tachycardia are associated with sub-optimal success rates and prolonged radiation exposure. Pre-procedure 3-D magnetic resonance imaging (MRI) has improved un...

Feasibility of real-time magnetic resonance imaging for catheter guidance in electrophysiology studies.

BACKGROUND Compared with fluoroscopy, the current imaging standard of care for guidance of electrophysiology procedures, magnetic resonance imaging (MRI) provides improved soft-tissue resolution and eliminates radiation exposure. However, because of inherent magnetic forces and electromagnetic interference, the MRI environment poses challenges for electrophysiology procedures. In this study, we...

Noninvasive assessment of tissue heating during cardiac radiofrequency ablation using MRI thermography.

BACKGROUND Failure to achieve properly localized, permanent tissue destruction is a common cause of arrhythmia recurrence after cardiac ablation. Current methods of assessing lesion size and location during cardiac radiofrequency ablation are unreliable or not suited for repeated assessment during the procedure. MRI thermography could be used to delineate permanent ablation lesions because tiss...
