The Mitral Valve

Mitral Physiology	PERIMOUNT Magna Mitral Advantage
In the mitral annulus, the fibrous anterior aspect is anatomically distinct from the muscular posterior aspect giving the annulus an overall saddle-shaped geometry.^1,2	The asymmetric valve design optimizes annular conformity while reference markers delineate the outflow tract for optimal hemodynamic positioning in the mitral annulus.
Mitral annular degenerative changes, such as calcification and scar tissue, can result in coaptive challenges between the sewing cuff and annular tissue.⁵	The valve has a wide, expansive sewing cuff with variable compliance that enhances the coaptive interface between cuff and mitral annular tissue while accommodating variability in suture technique.
Left ventricular wall injury and outflow tract obstruction have been known to result from projection of the stent into the left ventricle.⁵	The PERIMOUNT Magna mitral valve has the lowest effective profile of any mitral tissue valve, giving it the lowest ventricular projection for any stented mitral valve in the industry.^3,4
