Implication

Feasibility of MRI-guided flutter ablation shown; leaves open multi-electrode catheter development for AF.

Key Points

To assess the safety and feasibility of using an MRI-compatible multi-electrode circular mapping catheter during cardiac magnetic resonance imaging and evaluate interference between imaging and electrophysiological systems.
Evaluated a multi-electrode, circular, steerable, MR-compatible diagnostic catheter in vivo in sheep (N = 5) positioned in the right atrium during standard 1.5T cardiac MRI sequences.
Quantified electrogram signal-to-noise ratios, MRI image artefacts, and catheter radiofrequency heating in phantom models.
Recorded high-quality diagnostic electrograms during continuous MRI acquisition, achieving maximal peak-to-peak signal-to-noise ratios between 5.8 and 165.
Preserved diagnostic MRI image quality with clinically compatible artefact levels and observed a maximum phantom temperature increase of 4°C.

Structured PICO

Is a multi-electrode MR-compatible circular mapping catheter safe and feasible for cardiac mapping during MRI in an in vivo sheep model?

Population

In vivo sheep model (N = 5) and phantom data

Intervention

Multi-electrode, circular, steerable, MR-compatible diagnostic catheter (MR-compatible Lasso) during 1.5T MRI

Outcome

Feasibility and safety of using the catheter during MRI for cardiac mapping, and level of interference between MR and electrophysiological systemssafety

A novel MR-compatible 10-pole circular mapping catheter demonstrates in vivo feasibility and safety, enabling simultaneous MRI and electrophysiological mapping.
