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 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.
