Abstract

From 1975 to 1989, over 1400 patients in the elderly population and over 1700 patients under 65 years of age received the Carpentier-Edwards standard (CE-Standard) and supra-annular porcine (CE-SAV) bioprotheses. The mean ages of the patients receiving the two protheses within the three subgroups of the elderly population-65-69 years, 70-79 years, and 80 years and over-were relatively similar. There was no statistically significant difference in the performance of the prostheses regarding structural valve deterioration (SVD) at seven years. The freedom from SVD for aortic valve replacement in the 65-69 years group at seven years was 98.7% +/- 1.3% for the CE-Standard and 98.7% +/- 1.0% for the CE-SAV, for both the 70-79 years group and the 80 years and over group the figure was 100% for both prostheses (p = NS). The freedom from SVD after mitral valve replacement in the 65-69 years group at seven years was 90.0% +/- 4.3% for the CE-Standard and 84.8% +/- 7.5% for the CE-SAV, for the 70-79 years group it was 95.3% +/- 3.2% and 95.5% +/- 3.6% respectively and for the 80 years and over group the figure was 100% for both prostheses (p = NS within groups). The long term freedom from SVD after aortic valve replacement was 98.4% +/- 3% at 15 years for the CE-Standard in the 65-69 years group, 94.9% +/- 5% at 13 years for the 70-79 years group and 100% at 13 years for the 80 years and over group.(ABSTRACT TRUNCATED AT 250 WORDS)
