Aortic valve stenosis (AVS) can result from heart abnormalities that may be hereditary, but it commonly develops in older adults due to scarring and calcium buildup in the valve cusps.

We also reconstructed 3-D aortic valve cusps using CTA imaging to calculate the aortic cusp surface areas. Data were collected to analyze the ratios and the correlation between aortic valve and ...
