Figure 1From: Arterial stiffness in severe aortic stenosis following Transcatheter Aortic Valve Implantation (TAVI) compared to Surgical Aortic Valve Replacement (SAVR)A) Time-Velocity curves derived using PMI software to calculate foot-foot delay (curve in ascending aorta is shifted over the measured delay as a visual verification of the result) B) Aortic cross sectional measurements made by manual planimetry (red contour) of the ascending aortic endovascular-blood pool interface at minimal and maximal distension.Back to article page
