In vivo radial strain measurements at the rabbit aortic bifurcation were made at different times during the cardiac cycle. At the peak of the pressure pulse, the radial strain at the bifurcation is positive in the plane perpendicular to the bifurcation but negative in the plane of the bifurcation. Thus the cross-sectional geometry at this location distorts from an elliptical shape in diastole toward a more circular shape in systole.
