IRVINE, Calif., Feb. 27, 2014 (GLOBE NEWSWIRE) -- MRI Interventions, Inc. (OTCQB:MRIC) announced today that its novel ClearTrace ® system for MRI-guided, catheter-based cardiac procedures will be featured in a presentation at the 7 th Annual Western Atrial Fibrillation (AF) Symposium on Feb. 28-March 1 in Park City, Utah. The Western AF Symposium assembles a distinguished faculty of physicians and researchers from five continents to discuss the disorder, its relationship to heart failure, standards for patient care and technical advancements in the field. On Friday, Dr. Ravi Ranjan, cardiologist at the University of Utah, will give a talk entitled "The AF Ablation Lesion Detected Using MRI," highlighting the need for real-time assessment of lesions during minimally invasive catheter-based cardiac ablation and the techniques developed to enable intraprocedural visualization using MRI Interventions' ClearTrace system. On Saturday, a related presentation will be given by Dr. Nassir Marrouche, Associate Professor of Medicine and Director of the Electrophysiology Lab at the University of Utah, and the Executive Director of the Comprehensive Arrhythmia Research & Management Center (CARMA), titled "MRI for AF: Lessons from DECAAF." The DECAAF study highlights two main factors that determine the success of a minimally invasive ablation procedure: the stage of atrial fibrosis before ablation therapy, and the amount of residual fibrosis after the treatment. The study ultimately concluded that atrial fibrosis appraised by delayed enhancement MRI was associated with the probability of recurrent arrhythmia, exhibiting the usefulness of using MRI to assess AF in patients. Dr. Marrouche's presentation on the DECAAF study will demonstrate the importance of MRI in staging and assessing AF patients, and Dr. Ranjan's talk will highlight the benefits of an MRI-guided catheter-based cardiac procedure. Talks entitled "MRI Detected Fibrosis vs. Electrical Mapping" by Dr. Pierre Jais, Professor of Cardiology, Centre Hospitalier Universitaire de Bordeaux, and "The AF Ventricle in MRI" by Dr. Chris McGann, Director of Imaging for the Division of Cardiovascular Medicine at the University of Utah, will also emphasize the increasing role of MRI in treating atrial fibrillation.
