Supravalvular aortic stenosis (SVAS) is a rare aortic system obstruction disease characterized by hourglass-shaped
stenosis located at the sinotubular junction (STJ).
Surgical repair is the most common treatment for SVAS.
However, evidence is still lacking to illustrate superior surgical technology.
In this study,they compared the surgical effects of
McGoon, Doty, and Brom procedures based on a threedimensional model of the aorta and its main branches by using CFD.
The result that McGoon,Doty, and Brom repair were found to efectively restore stable blood fow despite symmetry of the aortic root.
