Table 5 Aortic valve apparatus/ascending aorta measurements pertinent for TAVR

Aortic annulus (AA) (virtual basal ring)

 • AA maximal diameter

 • AA perpendicular minimal diameter

 • AA average diameter

 • AA cross-sectional area (CSA)

 • AA circumference

Aortic valve

 • Cuspidity

 • Comissure calcifications

 • Aortic annulus calcifications

 • Severely calcified cusp that might compromise coronary the artery ostia: yes/no

Ascending aorta

 • Width at 40 mm from the annulus

 • Position relative to the sternum

Sinuses of Valsalva

 • Maximum diameter

 • Height

 • Sinotubular junction maximum diameter

 • Distance from the aortic annular plane to the coronary artery ostia
