Related valve dysfunction in bioprostheses

In Stentless bioprosthesis proximal joint of the prosthesis may loosen , causing blood between aortic wall and valve can come . When valve thrombosis there arises an increase in the gradient and an increase in the back flow ( leakage ) due to the larger mass, to enable the valve closes slowly.
