Aortic Replacement valves Hemodynamics in regards to Blood Stasis and Residence time

The aortic valve hemodynamics are heavily influenced by several factors. We have previously showed how replacement valve sizing can play a large role in controlling residence time and blood stasis inside the sinus bulge of the aorta. This year we will present a continuation of this work and describe how other surgical factors can affect the residence time around the aortic valves. We will focus on the ratio of valve and sinus size, valve mounting geometry and valve eccentricity and on how these factors can increase blood stasis. These findings present a clinically relevant framework for understanding the flow caused by surgically implanted aortic valves.
