Development of a twin-flap, porous ceramic mitral valve prosthesis

The pressure drop in most existing cardiac valve prostheses is at least ten times greater than for healthy valves. Steady flow testing indicates that the causes are (i) poor orifice diameter/sewing ring diameter ratio; (ii) occluding mechanism causes obstruction in the region of highest blood veloci...
