Implication

Supports feasibility of MR/CT-electroanatomic integration for AF ablation in one case; leaves open prospective validation before broader use.

Structured PICO

Is catheter ablation guided by integrated 3D MR/CT images and electroanatomic mapping feasible and accurate in patients with drug-refractory atrial fibrillation?

Population

16 consecutive patients with drug-refractory atrial fibrillation

Intervention

Catheter ablation guided by a 3D electroanatomic mapping system integrated with preacquired gadolinium-enhanced MR (n=8) or contrast-enhanced high-resolution CT (n=8) images

Outcome

Accuracy of image registration (distance between the surface of the registered 3D MR/CT LA reconstruction and multiple electroanatomic map points) and procedural complicationssurrogate

Integration of 3D MR/CT images with electroanatomic mapping is feasible and provides accurate anatomic guidance for catheter ablation of atrial fibrillation.
