Abstract

BACKGROUND: Total aortic arch replacement (TOTAL) is a complicated operation and has traditionally required deep hypothermic circulatory arrest. In this study, the impact of moderate hypothermic circulatory arrest (MHCA) and antegrade cerebral perfusion (ACP) for TOTAL were examined. METHODS: The ARCH International aortic database was queried and 3,265 patients undergoing TOTAL using ACP were identified. Patients were divided into groups based on lowest cooling temperature: MHCA (20° to 28°C) or deep hypothermia (DHCA) (12° to 20°C). Propensity-matched scoring using 15 variables was used in 669 matched pairs. Multivariable analyses were performed. RESULTS: In the unmatched cohort, more patie..
