Balance in covariates before and after propensity matching. (ASCP = antegrade selective cerebral perfusion; CAD = coronary artery disease; CPB = cardiopulmonary bypass; COPD = chronic obstructive pulmonary disease; CVD = cerebrovascular disease;SDAM = standardized difference after matching; SDBM = standardized difference before matching; TAAD/IMH = type A acute aortic dissection or intramural hematoma.)
