[A mechanical heart valve prosthesis with a spherical shape and open center].
A mechanical valve prosthesis is described with central blood flow. The generations I and II of the mechanical valve obstruct the blood flow and cause turbulence with undesirable consequences. The opening in the centre of Simkovic-Bolf valve preserves the laminar blood flow, reduces the trauma of blood and myocardium stress. Our new valve represents a mechanical valve prosthesis of generation III. (Fig. 5, Ref. 16.).
