Standard measurements of the aortic root in pre-TAVR computed tomography. (A) Aortic annulus major/minor diameters and perimeter. (B) Sinus of Valsalva width. (C) Coronary ostia height. (D) Sinotubular junction height.

Figure 2.
Computed tomography assessment of peripheral vasculature. Left panel: Curved multiplanar reconstruction of the thoracic and abdominal aorta and left iliac system showing no significant obstructive lesion and mild calcification. Right panel: Short-axis minimal luminal diameter of the left external iliac artery.
