Transcatheter Aortic Valve Replacement Planning
Severe aortic valve stenosis is managed by valve replacement which may be performed surgically or by transcatheter procedure. Computed Tomography (CT) plays an important role in the pre-procedure planning for transcatheter valve replacement. CT is utilized for the assessment of aortic root anatomy to determine appropriate size of artificial valve and also the assessment of arteries for transcatheter access. Application of appropriate CT scanning techniques, image reconstruction, and post-processing is crucial in accurate planning for patient management and surgical decision making.
