Expandable surgical heart valve indicators

A surgical prosthetic heart valve configured for open heart surgical implantation having a labeled valve size selected from a range, in 2 mm increments, between 19 and 33 mm, comprising:

• a support frame defining a flow orifice therethrough, and the flow orifice has a diameter equal to the labeled valve size, the support frame defining a dimensionally stable circumferential base modified to permit a limited amount of post-implant expansion when subjected to radial outward forces from within;
• a peripheral sewing ring around the circumferential base formed of suture-permeable material and configured for anchoring the valve to a native annulus using sutures;
• a plurality of leaflets ensuring one-way flow through the flow orifice;
• and
• a valve-size indicator on the support frame indicating the labeled valve size, and a valve-type indicator on the support frame that signifies the capability of the support frame for post-implant expansion.
