heart valve prosthesis

heart valve pros·the·sis

replacement of a cardiac valve removed for disease by either a mechanical or a biologically derived artificial valve.

heart valve prosthesis

Heart surgery A natural–eg, porcine or synthetic valve used to replace a damaged–stenosed or 'insufficient' cardiac valve; ±50,000 are performed/yr–US. See Shiley valve.
