Since the RV and LV, in this loop, appear to have normal ejection fractions, the volume entering the RV during diastole must exceed the volume of blood entering the LV during diastole. RV volume overload from fluid overload or a shunt (ASD) that is increasing the amount of blood in the RV at the end of diastole must be present. Other causes include constrictive pericarditis (from Still's disease), mechanical dyssynchrony from abberent conduction, pulmonary hypertension, left ventricular unloading (IABP), total absence of the pericardium, Valsalva maneuver, and an LVAD, |
