Transcatheter aortic valve implantation (TAVI) has evolved to standard treatment of severe aortic stenosis in patients with an intermediate to high surgical risk. Computed tomography coronary angiography (CTCA) could partially replace invasive coronary angiography to diagnose significant coronary artery disease in the work-up for TAVI.

CT imaging plays an important role in procedural planning for TAVI/TAVR and should be a fully integrated component of any TAVI/TAVR program. The use of CT in TAVI/TAVR is multifaceted and should include appropriate image acquisition and reconstruction as well as the comprehensive assessment the aortic root and vascular access.

Assessment of CAD prior to TAVI is recommended by current guidelines and is mainly performed via invasive coronary angiography (ICA). In this study we analyzed the ability of coronary CT-angiography (cCTA) to rule out significant CAD (stenosis ≥ 50%) during routine pre-TAVI evaluation in patients with high pre-test probability for CAD.

Multislice computed tomography (MSCT) is routine prior to TAVI for procedural planning. The MSCT may be used for concomitant CT coronary angiography (CTCA), allowing for an evaluation of CAD without a significant additional burden to the patient or healthcare system, and may potentially expedite the treatment of AS.
