Key result
Registration of rotational angiography-based left atrial reconstructions using 3D intracardiac echocardiography is feasible and accurate, with a mean deviation of 2.6 ± 0.5 mm between shells.
Why the study?
Does registration of rotational angiography-based left atrial reconstructions using intracardiac echocardiography provide accurate imaging in patients undergoing atrial fibrillation ablation?

Absolute Event Rate: 2.6% vs 2.7%
Intraprocedural 3D reconstruction of the left atrium and pulmonary veins using rotational angiography registered with 3D ICE is feasible and accurate without the need for additional electroanatomical mapping points.

May enable accurate intraprocedural LA reconstruction without extra mapping in AF ablation; leaves open effects on outcomes.
Nölker et al. (2011) conducted an observational in Atrial fibrillation (n=22). Registration of rotational angiography-based 3D reconstructions using 3D intracardiac echocardiography (ICE) vs. Addition of electroanatomical mapping (EAM) points was evaluated on Deviation between rotational angiography and ICE-based 3D shells. Registration of rotational angiography-based left atrial reconstructions using 3D intracardiac echocardiography is feasible and accurate, with a mean deviation of 2.6 ± 0.5 mm between shells.
