Moderate versus deep hypothermic circulatory arrest for ascending aorta and aortic arch surgeries using open distal anastomosis technique

MHCA with ACP achieved very good and comparable results to DHCA with RCP for ascending and aortic reconstruction. Furthermore, MHCA significantly shortened total operative, cardiopulmonary bypass and ischaemic times and, basically, decreased transfusion requirements compared with the former strategy and consequently may lead to better patient's outcome.
