The Right Ventricle: A Comprehensive Review From Anatomy
... Whereas the LV is conical, the RV is more triangular and semilunar in form on vertical plans. The RV differs from the LV in that the former has strict trabeculae, a moderator band, and inter-valve fibrous tissues. Interestingly, the muscle mass of the RV is about one-sixth that of the LV. This could ...
