Hyperpyrexia complicating low fixed cardiac output.
A 41-year-old woman with end-stage mitral and aortic stenosis developed the cycle of low cardiac output, peripheral vasoconstriction, increased core temperature, and cardiac decompensation. This was interrupted by core cooling utilizing iced gastric lavage. We propose that her severe hyperthermia was caused or abetted by her low cardiac output.
