Answers are grounded in this paper and cite their sources.
Moderate hypothermia (≥24 and ≤28°C) with hypothermic circulatory arrest appears safe for patients undergoing proximal aortic reoperations.
Moderate hypothermia for HCA during ACP is being used with increasing frequency, but has not been thoroughly evaluated in patients undergoing cardiovascular reoperations. Our experience suggests that in patients with previous cardiac surgery who are undergoing hemiarch and total aortic arch operations, moderate hypothermia is safe and produces respectable results.
