Baseline and Intraoperative Data
Patient characteristics are presented in Table 1. Bicuspid aortic valve was less common in the ATAAD group (0% vs 32%,p< 0.01), and proximal surgery was less extensive with fewer root replacements in the ATAAD group (p< 0.001) compared to the control group. Cardiopulmonary bypass time was shorter in the ATAAD group (160 (±36) min vs 208 (±60) min,p< 0.01) as well as aortic cross-clamping (75 (±31) min vs 139 (±44) min, p< 0.001). The lowest core temperature was significantly lower in the ATAAD group (20.0 (±2.8)°C vs 30.5 (±3.1)°C, p< 0.001).
