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.
在10只狗身上，在40天的过程中诱导左回旋支冠状动脉狭窄超过75%（使用Ameroid环）。冠状动脉搭桥手术后1小时内（n = 6），由心内膜下灌注不足组成的心肌血流（MBF）分布不均得到改善，但未完全消除。冠状动脉搭桥手术后一年（n = 4），MBF及其心内膜/心外膜分布正常。只有在诱导冠状动脉扩张时，搭桥血流量及其血流分布才是MBF及其心肌内分布的有用指标。
