Malchano et al. (2006) conducted an observational in Atrial fibrillation (n=13). Integration of preprocedural cardiac imaging (CT/MRI) with real-time electroanatomical mapping was evaluated on Alignment accuracy of integrated images with EAM data. Integrating preacquired cardiac CT/MR images with real-time electroanatomical mapping to guide left atrial catheter ablation is feasible, with optimal alignment occurring during expiration.
