Natural History
Bicuspid aortic valve have two distinct anatomical configurations:
- Antero-posterior orientation of the commissures resulting in right and left cusps. This occurs in approximately 53 percent of cases.[1]
- 47 percent of patients have commissures on right and left sides of annulus resulting in anterior and posterior cusps.[1]
Bicuspid aortic valve, during childhood functions without any significant pressure gradient. However, the thickening and calcification of the valves may be detectable pathologically and on echocardiography by second decade[2].
