title: Early aortic bioprosthetic valve deterioration in an octogenarian.
abstract: We experienced extremely early aortic bioprosthetic valve deterioration with leaflet calcification and stiffening 2 1/2 years after aortic valve replacement in a female octogenarian. We could not identify the possible reason for this devastating complication; however, daily calcium supplement consumption may play a role of acceleration of calcium deposition in the leaflets of implanted bioprosthetic heart valves.
