MRI-guided procedures

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

This chapter surveys applications of preprocedure magnetic resonance imaging (MRI) for guidance of atrial fibrillation (AF) ablation and provides an update on the progress toward full MRI guidance of electrophysiology procedures. Pulmonary vein (PV) variants are common and are relevant for planning ablation strategy. Electroanatomic mapping systems (EAM) is an important adjunct for guiding complex EP procedures and can also be performed in the MRI scanner. Current work focuses on taking MRI-guided EP from feasibility to safe and effective practice in patients. This includes developing reliable techniques for acute ablation lesion imaging, optimizing device visualization and navigation, integrated visualization of real-time MRI (rtMRI) with 3D anatomy and electrograms, developing full featured, MRI-compatible electrogram recording and pacing systems, and constructing clinical-grade MRI safe EP devices. The most straightforward aspect of MRI safety is the avoidance of ferromagnetic materials that could experience significant forces when brought close to the scanner.
