BackgroundValve-sparing root replacement (VSRR) has been associated with good survival and low rates of valve-related complications (VRCs). Whether these advantages are present irrespective of patient comorbidity or age is unclear. The aim of this study was to analyze survival and frequency of VRCs in relation to patient comorbidity and age.MethodsBetween October 1995 and December 2021, 1156 patients with a bicuspid or tricuspid aortic valve were treated by root remodeling. The mean patient age was 53.3 ± 14 years, and 973 (84%) were male. The mean duration of follow-up was 6.7 ± 5.5 years (median, 5.9 years), and follow-up was 95% complete (7746 patient-years). We analyzed the population according to comorbidity and age at surgery. A discriminating cutoff for the effect of age was determined using receiver operating characteristic curve (ROC) analysis.ResultsMean survival at 15 years was 74.7 ± 2.5%. Deceased patients were older (mean, 65.3 ± 12 years vs 51.6 ± 14.1 years; P < .001) at the time of surgery and had more comorbidities (coronary artery disease [CAD], 28.4% vs 9.8%; P < .001). The sole significant adjusted predictor was age (P < .001). By ROC analysis (area under the curve, 0.780), the optimal cutoff for age was 61 years. Survival was 87.1 ± 2.8% at 15 years in patients age <61 years, compared to 55.3 ± 4.3% in patients age >61 years (P < .0001). Using competing risk analysis, VRC-free survival at 15 years was 66.8% at 15 years, including 76.7% in patients age <61 years and 52.4% in those age >61 years (P < .0001).ConclusionsVSRR is associated with a low incidence of VRC and excellent durability. Survival is decreased in the presence of comorbidities, mainly CAD, and patient age >61 years. Despite lower survival, freedom from VRC is good.Copyright © 2023 The American Association for Thoracic Surgery. Published by Elsevier Inc. All rights reserved.
