ABSTRACT:
In a cardiac valve prosthesis, the journal pins, by which the closing body is supported to be swiveled in the valve ring, are received in through holes of the valve ring and can be moved into different positions in these through holes. Thereby, the journal pins are subjected to a circumfluent blood streams, reducing the danger of thrombi being formed at the supporting areas.
