  • Continuous variables compared using Mann-Whitney U test, categorical variables via χ2 or Fisher’s exact test. Matched data compared using Wilcoxon signed-rank test or McNemar’s test for related samples. When comparing Kaplan-Meier estimates, the log-rank test was used. Details on all reinterventions are shown in the online supplemental data.

  • AR, aortic regurgitation; Asc, ascending aorta; AV, aortic valve; PEARS, personalised external aortic root support; VSRR, valve-sparing root replacement.
