Lion of the Right ventricle
Lion of the Right ventricle – Oblique septal fibers
The septum is the lion of RV function – because the right ventricle must rely upon this intrinsic twisting function of oblique septal fibers to maintain output against increased pulmonary vascular resistance.
Studies show
- RV function is determined by the interaction of its lateral wall and the obliquely orientated fibres of the septum, which he nominates as the ‘Lion of the Right ventricle’,
- MRI studies that indicate RV longitudinal function (upon which RV ejection and filling relies on) is due to the septal twisting and untwisting.
