[Experimental coronary bypass operation: distribution of myocardial blood flow early and after one year].
In 10 dogs a stenosis greater than 75% of the left circumflex coronary artery is induced (Ameroid) in the course of 40 days. Within 1 hour after coronary artery bypass operation (n = 6) maldistribution of myocardial blood flow (MBF), consisting of a subendocardial perfusion deficit, is improved but not completely abolished. One year after coronary bypass operation (n = 4) MBF and its endo/epi-distribution is normal. Bypass flow and its flow profile are useful indicators of MBF and its intramyocardial distribution only when coronary dilation is induced.
