Real-time MRI-guided Electrophysiology

Real-time MRI-guided Electrophysiology

Since the first report on the feasibility of real-time MRI-guided cardiac ablation procedures in 2008, several publications have underlined the future potential of purely MR-based EP diagnosis and treatment. Compared to conventional imaging and mapping solutions used in cardiac catheter ablation, MRI provides outstanding soft-tissue characterization and spatial resolution. MRI-compatible catheters are under development to allow for real-time 3D catheter tracking and direct visualization of lesion formation without radiation exposure for the staff and patients. Enhanced identification and targeting of anatomic structures of interest including neighboring structures, such as the esophagus and pericardial space, can help to avoid complications and to increase procedural success rate. Clinical studies show that in the future, real-time MRI guidance may help to avoid incomplete lesion formation and to allow for a more successful treatment of complex arrhythmias without radiation exposure.1
