WebAn intracardiac shunt results in flow of blood from left-sided to right-sided cardiac chambers or vice versa. With ventricular septal defects, flow is often left to right as a result of higher left-sided pressures. Atrial septal defects can result in a shunt in either direction. Because of the flow of oxygenated blood into right-sided chambers ...
