Visual inspection of the m-FAM reconstruction and comparison with the CTA:
The three-dimensional reconstructions of the LA obtained with the m-FAM module were shown to the operator prior to the initiation of the ablation and visually compared to the matching CT scan and to Carto location points and VisiTag’s. Importantly the operator was blinded to the CT scan of the patient during the LA mapping and m-FAM reconstruction. The comparison between the m-FAM reconstruction and the cardiac CTA of the same patient included:
-the LA body morphology
-the presence of common os pulmonary veins
-the PV antrum at the level of WACA
The comparison between the m-FAM and the cardiac CTA was graded as good or poor.
