Methods
We retrospectively reviewed the records of patients who had undergone
aortic arch repair with Release and Perfuse Technique (RPT) or standard
Frozen Elephant Trunk (FET) at our Institution between January 2018 and
May 2021. Primary endpoints were the comparison of circulatory arrest
time, perioperative variables, and complications between two groups. A
propensity score weighting approach was used for data analysis.
