Abstract

Recently, Bentall procedure is commonly performed for annuloaortic ectasia with aortic regurgitation or dissecting aneurysm. And the operative results are improving. In this study, we evaluated results of the St. Jude Medical (SJM) and Carbomedics (CM) valves which were used in this procedure. From 1979 to 1994, 87 SJM valves and 22 CM valves were implanted in the aortic position of Bentall procedure. Total follow-up was 528.6 years in the SJM group and 56.5 years in the CM group. According to the Kaplan-Meier actuarial method and the Cox-Mantel statistical analysis, actuarial survival, thromboembolism free rate, reoperation free rate, event free rate were not different between the SJM and CM groups. These results suggest that, current selection of the SJM and CM valves would be acceptable in Bentall procedure.
