Does intra-procedural CBCT provide comparable integration accuracy and reduced radiation compared to pre-procedural MSCT for guiding catheter ablation in patients with drug-refractory atrial fibrillation?
Intra-procedural CBCT is a feasible and accurate alternative to pre-procedural MSCT for image integration during atrial fibrillation ablation, offering the advantage of reduced radiation exposure.
Ejima et al. (2009) conducted an observational in drug-refractory atrial fibrillation (n=24). Intra-procedural cone-beam computed tomography (CBCT) vs. Pre-procedural multi-slice CT (MSCT) was evaluated on Integration accuracy (point-to-surface distance) of each image and electroanatomical map. Intra-procedural cone-beam computed tomography provided similar integration accuracy to pre-procedural multi-slice CT, while significantly reducing radiation exposure (P<0.001).
