Cardiac electrical dysfunction can be assessed by mini-invasive electrophysiological (EP) mapping. Being able to collect electrical data simultaneously to MR acquisition would simplify the interventional procedure, allow for reduction of examination duration for the patients and clinicians, and reduce registration errors. This study presents simultaneous MR-EP using a 10 poles, circular, EP catheter. Evaluation of the MR-compatibility is presented, together with simultaneous MR-EP measurements obtained in vivo on a large animal model. The electrograms obtained in the MR scanner operating at 1.5 T were compared to measurement performed under identical conditions in the adjacent catheter lab under X-Ray fluoroscopy.
