BackgroundThe aim of this study was to analyze early postoperative outcomes and 2-year survival after aortic valve replacement (AVR) with the sutureless Perceval bioprosthesis (Sorin Biomedica Cardio Srl, Salluggia, Italy) performed through ministernotomy compared with full sternotomy.MethodsThis was a study of 267 consecutive patients who underwent isolated AVR with the sutureless Perceval bioprosthesis between 2007 and 2014 at 6 European centers. Of these, 189 (70.8%) were performed through ministernotomy and 78 through a full sternotomy. Propensity score matching was used to reduce selection bias.ResultsIn the overall cohort of ministernotomy and full sternotomy patients, in-hospital mortality was 1.1% and 2.6% and 2-year survival was 92% and 91%, respectively. Propensity score matching resulted in 56 pairs with similar characteristics and operative risk. Aortic cross-clamp (44 minutes in both groups, p = 0.931) and cardiopulmonary bypass time (69 vs 74 minutes, p = 0.363) did not differ between the groups. Apart from higher values in the ministernotomy group for postoperative peak gradients (28.1 vs 23.3 mm Hg, p = 0.026) and mean aortic valve gradients (15.2 vs 11.7 mm Hg, p = 0.011), early postoperative outcomes did not differ in the propensity-matched cohort. There were no differences in the in-hospital mortality rate or 2-year survival between the groups.ConclusionsAVR with the sutureless Perceval bioprosthesis through a ministernotomy was a safe and reproducible procedure that was not associated with prolonged aortic cross-clamp or cardiopulmonary bypass time compared with a full sternotomy. Early postoperative outcomes and 2-year survival were comparable between patients undergoing ministernotomy and full sternotomy.Copyright © 2015 The Society of Thoracic Surgeons.
