Aortic Valve Disease

Aorta area ratio can be used in noninvasive quantitation of flow turbulence

Published in Cardiovascular Week, November 3rd, 2003

Postvalvular aorta to valvular orifice cross-sectional areas ratio can be used in noninvasive quantitation of blood flow turbulence in aortic valve disease.

According to a study from France, "Previous experimental studies have demonstrated that aortic valve disease is associated with significant downstream turbulence (T). In this study, we developed a noninvasive method on the basis of Doppler velocity recording for quantitating aortic blood flow T in patients with aortic valve disease.

"The instantaneous blood velocity at a point in the aorta is equal to the sum of a mean periodic velocity component with a random or turbulent velocity component....
