Mongrel dogs were subjected to cardiopulmonary bypass with hemodilution and to normothermic anoxic arrest for 30 minutes, to study the subepicardial and the subendocardial myocardial ultructure and the DPTI/TTI ratio. "No-reflow phenomenon" was demonstrated in the myocardium after cardiopulmonary bypass, associated with normothermic anoxic arrest. No-reflow phenomenon was a contributing factor to subendocardial ischemia in the normotrophied ventricle after open-heart surgery. Severe hemodilution with hemoglobin less than 5.0 g% resulted in irreversible damage in both myocardial layers.
