Role of sinus wall compliance in aortic leaflet function.

Author information

Carolinas Heart Institute and the Heineman Medical Research Laboratory, Carolinas Medical Center, Charlotte, North Carolina, USA.


Functional morphology of the normal aortic root was studied in vitro using 500 frames/s cinematography. Stiffening of the aortic wall by spraying its exterior with plastic adhesive led to compromised function of the leaflets, a phenomenon that may play a role in valve degeneration as it occurs in old-age fibrosis, atherosclerosis, or in connection with certain surgical procedures.
