MRI Guided Ablation


The University of Utah CARMA Center, in collaboration with industry partners Sugivision Inc. and Siemens Corporate Research, is conducting pioneering research into the integration of real time magnetic resonance imaging and catheter ablation of atrial fibrillation.  Catheter ablation has revolutionized the treatment of patients with cardiac arrhythmias, and yet success rates for complex ablation procedure, such as ablation for atrial fibrillation, remain in the range of 60 - 80%.  While numerous technological advancements in the field are improving the success and safety of these procedures, one glaring hurdle to progress is the inability of physicians to immediately assess the therapeutic burns they have created.  Leveraging the ability of MRI to image changes cardiac tissue researchers at the CARMA Center hope to solve this problem by moving the ablation procedure into the MRI.

While imaging of lesions during an ablation procedure would greatly guide and improve the treatment physicians are able to provide, it also creates unique challenges.  In particular, working in a high magnetic field can interfere with much of the equipment and electronics necessary for ablation procedures. To overcome these challenges, the CARMA Center has gathered together leaders in the fields of imaging, electronics, image processing, and electrophysiology.  These experts, in combination with industry partners, are tackling the challenge of real time MRI guided ablation.
