Background: Visualization of the inner anatomical relationship of the pulmonary veins (PVs) and left atrium (LA) is important for achieving a better success rate and avoiding complications in circumferential LA ablation for atrial fibrillation (AF).

Methods And Results: Twelve patients with AF underwent computed tomography and novel post-processing images that emphasized the boundaries of the PVs and LA were produced.

Conclusions: The "Transparent View" images enabled visualization of the inner anatomical relationship of the PVs and LA in the same geometry as in pulmonary venography in all cases.
