Data presented as median (interquartile range) for continuous variables and number (percentage) for categorical variables. Abbreviations: CAD, coronary artery disease; MI, myocardial infarction; CHF, congestive heart failure; BAV, bicuspid aortic valve; CABG, coronary artery bypass grafting. 1 patient in the Valsalva group underwent previous aortic valve repair (resuspension).
