ABSTRACT:
In a prosthetic heart valve comprising a generally annular stent and at least two obturators mounted in the stent so as to be above to pivot between an open position and a closed position, the stent is provided with at least one element which projects inwardly of the stent itself, while each of the obturators has recesses which cooperate with the projecting element of the stent with clearance in a generally-hinged configuration which enables the obturators to pivot between the open position and the closed position.
