*, Median, 1st quartile–3rd quartile. All nominal data expressed as presented as n and percentage of total population and compared with Pearson χ2 or Fisher’s exact test. Continuous data expressed as mean ± standard deviation with comparisons calculated with two-tailed paired Student’s t-test. Year of operation is expressed as median with interquartile range and analyzed with median test. CVG, composite valve-graft conduit; VSR, valve sparing root replacement; AV, Aortic Valve; AVR, Aortic Valve Replacement; CABG, coronary artery bypass grafting.
