TABLE 2.

Comparison of aortic root computerized tomography angiography (CTA) measurements between the deep implantation group and the non-deep implantation group of the Venus-A prosthesis.

Aortic root	Deep implantation group (n = 17)	Non-deep implantation group (n = 36)	Total (n = 53)	P-value
Annular diameter	27.3 ± 3.2	25.9 ± 2.9	26.5 ± 3.0	0.1325
(mm, $\overline{x}\pm s$)
LVOT diameter	28.5 ± 3.8	26.0 ± 3.3	26.9 ± 3.9	0.0213
(mm, $\overline{x}\pm s$)
SOV diameter	33.0 ± 5.2	34.3 ± 4.8	33.9 ± 5.0	0.3905
(mm, $\overline{x}\pm s$)
Calcification volume	575.6 ± 272.0	797.1 ± 412.3	730.6 ± 383.7	0.1858
(850 HU, mm3, $\overline{x}\pm s$)
Aortic root angulation	54.9 ± 9.3	47.7 ± 10.4	50.6 ± 10.4	0.0263
(°, $\overline{x}\pm s$)
LCA height	13.8 ± 3.5	15.7 ± 3.9	15.0 ± 5.1	0.1186
(mm, $\overline{x}\pm s$)
RCA height	16.6 ± 4.0	16.7 ± 3.1	16.6 ± 4.7	0.4705
(mm, $\overline{x}\pm s$)
STJ diameter	33.5 ± 3.9	32.3 ± 5.2	32.6 ± 7.1	0.4356
(mm, $\overline{x}\pm s$)

All diameters measured by CTA in the table were calculated from the circumference. Aortic root angulation, angle between plane of aortic valve annulus and horizontal plane; LVOT, left ventricular outflow tract; SOV, sinus of Valsalva; LCA, left coronary artery; RCA, right coronary artery; STJ, sinotubular junction.
