DYNAMIC CONFORMATIONAL CHANGES OF THE LEFT VENTRICULAR OUTFLOW TRACT COMPARED TO THE AORTIC ANNULUS AND IMPLICATIONS ON TRANSCATHETER AORTIC VALVE SELECTION AND SIZING

ECG-gated computed tomography angiography (CTA) has become the standard for assessing the aortic root prior to transcatheter aortic valve replacement (TAVR). Current techniques rely primarily on systolic annular sizing for the selection and sizing of valve prostheses. We sought to evaluate the
