Geometric characteristics of bicuspid aortic valves.

ABSTRACT:

Objective

We studied the coaptation angles α and β in bicuspid aortic valve geometry from computed tomography scan images.

Methods

In 45 patients, we calculated the coaptation angle α (the angle between the nonfused commissures crossing the center of coaptation), angle β (between the nonfused commissures crossing the center of the reference circle), angles γ₁ and γ₂ and ε₁ and ε₂ (angle between the nonfused commissures and the coaptation point at the raphe or the perfect midpoint, respectively), the length of the raphe, the absolute and relative sinuses' surfaces (relative to the perfect circle and the percentage exceeding the ideal circle). Spearman correlation was employed to investigate the associations among all parameters.
