We know that the left ventricle generates twisting, rotation, and torsion but the right ventricle is just draped around it but has little inherent twisting or torsion!
I believe that we are dealing with a novel problem that has not seriously been studied.
Thank you very much for your kind attention.

Apical circumferential motion of the right and the left ventricles in healthy subjects described with speckle tracking. Gustafsson U1, Lindqvist P, Waldenström A.
they concluded that......the left ventricle displayed uniform rotation, the right ventricle showed heterogeneous rotation, resulting overall in almost no rotation but in a "tightening belt" motion.
Thanks a lot for your answer. I have read their studies. but as you know, frist of all we have to give an exact/or the best estimation of a right ventricular reconstruction/or modeling. Gusafsson et al. works are based on ellipsoid modeling of the RV and LV!! and then Speckle tracking would be applied on such this RV modeling. But I think we wolud miss a lot of data of RV becuase of the complexity of the geometrical shape of RV not only statically but also dynamically at the same time. Of course there are some geometrization/triangulation of the RV based on taged MRI which shows RV moves longitudinally and then rotates clockwise at the apical level in systolic phase. I feel something is wrong and a new technique needs to model RV, I do not mean image reconstruction of the RV like CMR studies........
