Use of "iSuite" During CMR-guided Electrophysiological Procedures
Study Details
Study Description
Brief Summary
The perpuse of this study is to investigate the feasibility of the Philips interventional MRI suite "iSuite" to create an electroanatomical map of the heart based on which the real-time location of the catheters can be correctly and reliably visualized during CMR-guided electrophysiological procedure (CMR-EP).

Outcome Measures
Primary Outcome Measures
- The feasibility of iSuite to create an electroanatomical map (EAM) of the heart during CMR-EP [Periprocedural]
To establish whether the visualization by iSuite is correct we will compare the location visualized by the EAM with the reference images as produced by the default cine MRI sequences at the target ablation location just prior to the RF ablation. The definition of correct visualization is: good agreement between the two modalities (EAM and cine MRI) based on visual assessment of the treating electrophysiologist and the supervising CMR expert. When no consensus is reached than the visualization is coded 'incorrect'. This outcome will be dichotomized and coded as 'correct visualization' or 'incorrect visualization'. This categorical variable will be expressed as counts and proportion with 95% confidence interval (CI).
Secondary Outcome Measures
- Procedural success as measured by electrical and anatomical confirmation of a complete ablation lesion at the end of the procedure: [Periprocedural]
Anatomical confirmation of a complete ablation lesion is defined as a continuous line of high signal intensity at the target location on the edema and fibrosis sequences of the CMR at the end of the procedure. This anatomical confirmation will be judged by the CMR expert that is present during the procedure and thus will not be blinded to the EP results. Procedural success and procedural complications will be reported as count and proportion with 95% CI.
- Procedural time [Periprocedural]
To investigate the procedure-by-procedure change in procedural times and total amount of CMR images needed until application of the first ablation lesion
- Complication rate [Periprocedural]
To investigate the complication rate of CMR-EP with the integration of iSuite.
