Depolarizing the heart with hyperkalemic cardioplegia solutions arrests the heart but is associated with an on-going, albeit lowered, metabolic demand that requires either hypothermia or intermittent/continuous delivery to attenuate the consequences of this ongoing demand (ie, ischemia). However, simplicity, visibility, economy, and avoiding the consequences of systemic hyperkalemia would make a single delivery of hypothermic cardioplegia desirable, especially during aortic arch repairs and other complex procedures that require long arrest times.
Fannelop and colleagues [1] have compared physiologic outcomes of a single infusion of Custodiol HTK (Odyssey Pharmaceuticals Inc, East Hanover, NJ) crystalloid cardioplegia solution with a multidose strategy
