Pericardial restraint may limit output after volume expansion in dogs; extends prior animal data but leaves open human translation.
Does opening the intact pericardium affect cardiac performance in open-chest dogs?
The intact pericardium exerts a moderate restrictive effect on cardiac performance after moderate blood volume expansion in a canine model.
Stokland et al. (1980) studied this question.
