Figure 1: An illustration of the spectrum of ventricular interdependence. Depicting the normal concavity of the IVS toward the LV throughout the cardiac cycle (a) Outline of the original description of Bernheim effect wherein concentric LVH detrimentally affects the RV function owing to exaggerated rightward movement of the IVS (b) Reverse-Bernheim effect wherein RV pressure or volume overload tends to result in septal flattening and a consequential “D” shaped LV in setting of RV dysfunction (c). (IVS: Inter-ventricular septum, LV: Left ventricle, LVH: Left ventricular hypertrophy, RV: Right ventricle).
