摘要: Abstract Primary tissue failure (structural valve deterioration) has been documented as the most prominent complication of porcine bioprostheses. The influence age on primary received limited consideration. From 1975 to 1986, 1,301 Carpentier-Edwards standard bioprostheses were implanted in 1,183 patients 1,201 operations. Of total number prostheses, 97.7% prior 1983. mean follow-up was 5.6 years and 97.5% complete. identified 96 (98 operations) at reoperation (95) or autopsy (3). One hundred four (104) prostheses involved. Thirty-one failed after aortic replacement (AVR), 49 mitral (MVR), 24 multiple-valve (18 patients).
