Figure 1
Fundamental functions and impact of the septum between both ventricle.
Figure 2
Look at the septal motion (or deformation): the interdependent leads to a paradoxical motion seen in M-mode and with the strain modality (yellow and light blue curves.
Figure 3
A) amplitude change of the mitral inflow according to the inspiration / expiration >25%. B-C) e’ septal >e’ lateral. D) delayed and weaker longitudinal deformation at the base than at the apex.

Functional role of complementary geometry in a common pericardium: Example of RV volume overload.
Figure 5
A) As a consequence of the right ventricle dilatation and dysfunction, the interaction with the left ventricle lead to a left ventricular dysfunction. B) Delayed deformation of the septum, even elongation in early systole: consequence of the volume overload of the right ventricle in a patient with a severe tricuspid regurgitation.
