Ventricular interdependence<br />

Plays Plays an an important important role role in right right ventricular ventricular function function<br />

In addition to a shared interventricular septum, there is<br />

continuity between the muscle fibers of the left and right<br />

ventricles, resulting in a mechanical union whereby left<br />

ventricular contraction augments right ventricular free wall<br />

contraction<br />

Experimental models have shown that 20 20% % to 40 40% % of RV<br />

systolic pressure and volume outflow results from left<br />

ventricular contraction<br />
