CT angiography-fluoroscopy fusion imaging for percutaneous transapical access.

Objectives: The aim of this proof-of-principle study is to validate the accuracy of fusion imaging for percutaneous transapical access (TA).

Background: Structural heart disease interventions, including TA, are commonly obtained under fluoroscopic guidance, which lacks important spatial information. Computed tomographic angiography (CTA)-fluoroscopy fusion imaging can provide the 3-dimensional information necessary for improved accuracy in planning and guidance of these interventions.
