Abstract

A_small_ASD_with right-to-left shunt is useful for off-loading a dysfunctional right ventricle postoperatively. However, an ASD with left-to-right shunt may not be as useful for a dysfunctional left ventricle. Experimental data is limited at present. Thus, we reconsider the related physiology to guide future approach.
