Data are presented as n (percentage) or mean ± standard deviation (SD). All groups were compared to standard SCR
AADA acute aortic dissection type A, AVS aortic valve sparing, COMP composite replacement, SCR supracommissural replacement, TAR total arch replacement
^aSince Debakey type 3 dissection were not included, rest of the cohort were DeBakey type 1 dissections
