MFR quantified using (82)Rb PET predicts hard cardiac events and MACE independent of the SSS and other parameters. Routine assessment of (82)Rb PET-quantified MFR could improve risk stratification for patients being investigated for ischemia.

Contemporary management of adult cardiac surgery under CPB still involves induction of mild to moderate systemic hypothermia. Significant practice variation exists across the country with respect to target temperatures for cooling and rewarming, as well as the site for temperature monitoring. This probably reflects the lack of definitive evidence. There is a need for well-conducted clinical trials to provide more robust evidence regarding temperature management.
