Abstract

Background: The modified Bentall procedure is still the treatment of choice for patients requiring combined replacement of the ascending aorta and aortic valve. We compared the long-term outcome of patients > 65 years of age undergoing Bentall procedure with biological vs mechanical valved conduits in a multi institutional study.Methods: A total of 282 patients, undergoing a Bentall operation (January 1994-May 2015), with a biological (Group 1, 173 patients) or a mechanical (Group 2, 109 patients) conduit were reviewed, the primary outcome being analysis of late survival and freedom from major adverse events.Results: Hospital mortality was 5% (9 patients) and 2% (2 patients) for Group 1 and Group 2 (p = 0.2). Median follow-up was 77 months (range Q1-Q3: 49-111) for Group 1 vs 107 months (range Q1-Q3: 63-145) for Group 2 (p < 0.001). A not statistically significant advantage in late survival was found in patients receiving mechanical valved conduits (36% for Group 1 vs 58% for Group 2 at 12 years; p = 0.09), although freedom from major adverse events was similar between the 2 groups (33% in Group 1 vs 50% in Group 2 at 12 years; p = 0.3).Conclusions: In conclusion, mechanical-valved conduits employed for the modified Bentall procedure show a trend towards an improved late survival in patients >= 65 years of age and particularly in those between 65 and 75 years, despite a higher incidence of major adverse events. Our results indicate the need for specific guidelines to better define the ideal age limit for each type of valved conduit. (C) 2019 Elsevier B.V. All rights reserved.
