It is due also to the advent of sophisticated, noninvasive, diagnostic technology which makes it possible to explore the motion of blood and of card

Turbulence induces high shear stress on the wall and also within the flowing fluid. When the flow becomes turbulent, viscous shear stress is no longer significant. This increase of the shear stress has been at

It is well-known that the presence of a stenosis within a large artery gives rise to a region of turbulent flow downstream of the obstruction (Giddens et al. 1976). When the flow is highly disturbed or turbulent, the pressure loss (pressure gradient) across the stenosis is

However, cineangiographic techniques do not provide an accurate assessment of the severity of AR because of their relatively gross estimation of the amount of regurgitant flow. The results of medical or operative tr

In this section, the intracardiac flow dynamics is assessed in representative cardiac anomalies—atrial septal defect (ASD), ventricular septal defect (VSD); and patent ductus arteriosus (PDA). Additionally, the blood flow pattern of the inter-atrial communication in patients with co
