摘要：
Minimally invasive balloon expandable transcatheter aortic valve replacement (TAVR) is currently the standard of care for patients with inoperable severe symptomatic aortic stenosis and is an acceptable alternative to traditional aortic valve replacement in selected high-risk operable patients. Multidetector computed tomography (MDCT) is an integral component of diagnostic workup prior to TAVR. We review the pivotal role of MDCT in patient selection by discussing pre-procedural assessment of iliofemoral, aortic root, and annular geometry. We summarize how MDCT can help guide percutaneous vascular access as well as accurately determine the correct co-axial valve plane and transcatheter valve size. Finally, we discuss how MDCT provides important information about long-term valve durability by assessing valve eccentricity, leaflet and stent integrity, valve recoil, and valve migration. © 2011 Springer Science+Business Media, LLC.
