Data presented as n (%), median (IQR), or mean ± standard deviation
TAR, total arch replacement; MVR, mitral valve replacement; MVP, mitral valvuloplasty; TVP, tricuspid valvuloplasty; CABG, coronary artery bypass graft; CPB, cardiopulmonary bypass; DHCA, deep hypothermic circulatory arrest
Bold values indicate significance at P < 0.05
^aP values indicate differences between survivors and deceased patients
