Device Selection for Transcatheter Aortic Valve Implantation

Abstract

Twenty years after the first implantation by Alain Cribier and his team, transcatheter aortic valve implantation (TAVI) has demonstrated its efficacy and safety in patients with symptomatic severe aortic stenosis with high, intermediate, and even low surgical risk. Consequently, its indications have expanded widely over the years, with the improvement of structural devices, operator’s experience, procedural techniques, and post-procedural management [1,2].

Utility of Coronary Computed Tomography Angiography in Patients Undergoing Transcatheter Aortic Valve Implantation: A Meta-Analysis and Meta-Regression Based on Published Data from 7458 Patients

“…Specifically, CT allows for detailed ana-tomic valve visualization and quantification of the grade of calcification. The degree and distribution of calcification can guide prosthetic valve choice and predict the risk of complications, such as pacemaker dependency and paravalvular leaks [10][11][12][13]. Accurate measurements of the aortic annulus, leaflets, and sinotubular junction are also critical for selecting appropriately sized prosthetic valves.…”
