The effects of myocardial contraction-induced convective acceleration on the development of axial mid-to-late ejection velocity profiles. Blunt profiles corresponding to the computed fluid dynamic solution are plotted at successive normalized tubular chamber lengths (distance from apex/axis length). Note the progressive sharp increase in the slope of the velocity profile at the endocardial surface; this slope is proportional to the shear stress exerted by ejected blood locally at the endocardial surface. High shear stress may have important epigenetic influences in hypertrophic cardiomyopathy. The axially uniform parabolic Poiseuille profiles are plotted for comparison.
