title: Computed tomography evaluation for transcatheter aortic valve implantation (TAVI): imaging of the aortic root and iliac arteries.
abstract: For patients with severe aortic stenosis, open-heart surgical valve replacement remains the current clinical standard with documented, excellent long-term outcome. Over the past few years, transcatheter aortic valve implantation (TAVI) has developed into a treatment alternative for high-risk patients with severe aortic stenosis. Because transcatheter valvular procedures are characterized by lack of exposure of the operative field, image guidance is critical. This Pictorial Essay describes the role of 3-dimensional imaging with multidetector row computed tomography for detailed reconstructions of the aortic valve, aortic root, and iliac arteries in the context of TAVI.
