- W4200374413 abstract "Abstract OBJECTIVES This study was conducted to examine the incidence and modes of the bioprosthetic valve failure of the porcine valve in the mitral position and compare them with those of the pericardial valve. METHODS This study included 240 patients (116 men [48.3%]; mean age, 74.87 ± 6.61 years) who underwent mitral valve replacement using the St. Jude Medical Epic bioprosthesis (Epic) (N = 125) or Carpentier–Edwards Perimount (CEP) pericardial valve (N = 115) from January 2000 to December 2020. RESULTS The median clinical follow-up durations in the Epic and CEP groups were 54.5 months (range, 0–111 months) and 81.5 months (range, 0–194 months), respectively. Structural valve degeneration (SVD) was observed in 9 patients (7.2%) in the Epic group and 11 patients (9.6%) in the CEP group. The rates of freedom from SVD at 3, 5 and 7 years were 97.7%, 90.5% and 75.5% in the Epic group and 100.0%, 96.1% and 90.0% in the CEP group, respectively. SVD reoperation was performed for 7 patients (5.6%) in the Epic group and 6 patients (5.2%) in the CEP group. The rates of freedom from SVD reoperation at 3, 5 and 7 years were 97.7%, 90.5% and 75.5% in the Epic group and 100%, 96.1% and 90.0% in the CEP group, respectively. Epic SVD was predominantly due to leaflet tearing, whereas CEP SVD was predominantly due to leaflet calcification and adhesion to the subvalvular apparatus. CONCLUSIONS SVD of the porcine valve was predominantly due to leaflet tearing. The rate of reoperation for SVD was slightly higher for the porcine valve in the mitral position than for the pericardial valve at adjusted survival analysis." @default.
