<p>A system for assembling a stented, bioprosthetic heart valve, comprising suturing means for suturing a biological valve coupled with a stent, wherein adjacent commissural portions of the biological valve are sutured together at a predetermined first distance S1, the biological valve includes an initial circumference D1, the stent includes an initial circumference Dm; and means for removing one or more sutures from the adjacent commissural portions of the biological valve resulting in adjacent commissural portions of the valve being sutured together a second predetermined distance S2, wherein the assembled stented, bioprosthetic valve includes a circumference D2, wherein D2 is greater than D1, and Dm is substantially equal to D2; wherein the leaflets of the biological valve include a coaptation circumference Di after implantation, and Di is less than Dm.</p> |
