TABLE 2.

P values of Mann-Whitney U tests for amplitude of angular undulation (AAU) of collagen and elastin fibers between the 2 ascending thoracic aortic aneurysm (ATAA) phenotypes (bicuspid aortic valve [BAV] and tricuspid aortic valve [TAV]) in 18 locations of the aortic wall: 3 radial (RAD) locations (media-intima [med-int], media, and adventitia-media [adv-med]) × 2 planes (Z-RAD and Θ-RAD) × 3 Θ regions (left coronary sinus [L], noncoronary sinus [N], and right coronary sinus [R]). Statistical analysis showed that AAU is increased in region L and decreased in the media of region N and in the region R of BAV-ATAA compared with TAV-ATAA. The AAU is increased in the adv-med of region N of BAV-ATAA versus TAV-ATAA

Med-int, Media-intima layer; Adv-med, adventitia-media layer; Z-RAD, longitudinal-radial plane; Θ-RAD, circumferential-radial plane; L, circumferential region with respect to left coronary sinus; N, circumferential region with respect to noncoronary sinus; R, circumferential region with respect to right coronary sinus.

Significant difference.
