摘要

Abstract Objectives Aortic root enlargement (ARE) lowers the risk of patient prosthesis mismatch after surgical aortic valve replacement (SAVR) in patients with small annular size. Whether ARE?is associated with increased operative mortality is controversial. This study compares the early and intermediate outcomes in patients undergoing SAVR with and without ARE. Methods All patients undergoing isolated SAVR with and without ARE from 2015 to 2020 were analyzed. Propensity‐matching was used to adjust for possible confounding variables. Kaplan–Meier analysis and log‐rank test were used to estimate and compare overall outcomes and survival in the study cohorts. Results Among 868 isolated SAVRs, ARE was performed in 54 (6.2%) patients. Before matching, mean age was similar but female sex (67.4% vs. 29.6%; SD: ?0.82) and previous AVR (18.9% vs. 3.9%; SD: ?0.48) were more common in patients undergoing SAVR?+?ARE versus SAVR alone. A bovine pericardial patch was used for 81.5%?(44 of 54) of ARE, with a Dacron patch in the rest. After propensity matching, the average cardiopulmonary bypass (138.2?±?34.9 vs. 102.9?±?33.0?min; p?
