Outcomes of Total Aortic Arch Replacement in a Canadian Nationwide Registry
This multicenter study compares outcomes of 250 elective total arch replacements with 728 elective hemiarch replacements in Canada, using propensity score matching to create 202 well-matched pairs. Findings reveal that while in-hospital mortality rates for total arch replacement are comparable to hemiarch repairs, total arch replacement is associated with higher rates of complications such as delirium and prolonged intubation.
