Intermittent cold blood cardioplegia
with retrograde coronary perfusion was demonstrated in 11 CABG
cases and the effects of myocardial protections were compared
with 11 cases of antegrade perfusion. We evaluated the effects
from the assistant perfusion time after aortic declamping, the
incidence of occurrence of spontaneous beating, the dose of catecholamin
required after CPB, and the changes in myocardial enzyme values.
The two groups were similar in age, ejection fractions, and the
extent of coronary artery disease. There were no cases of death
and no PMI in all 22 cases, and the mean number of grafts and
aortic clamping time were similar in the two groups. Concerning
the effects of myocardial protections, there were no significant
differences in any items in the two groups. We conclude that
intermittent cold blood cardioplegia with retrograde coronary
perfusion provides the same myocardial protective effects as
the antegrade perfusion in CABG cases.
