An MR-EP suite was developed that closely integrates all components required for clinical EP procedures. This includes wireless transmission of the ECG from the patient monitor to the EP recorder, automatic transmission of activation time delays from the EP recorder with on-the-fly generation of color-coded time maps based on a cardiac model, and automatic planning of scan orientations based on the position of the active tracking catheter. The suite was evaluated in pre-clinical mapping and ablation sessions in pigs. It enabled time-efficient mapping and ablation including catheter-navigated monitoring of catheter-tissue contact and lesion formation including wall thickening.
