Abstract

After coronary occlusion a zone of intermediate flow is found between ischemic and normal myocardium. To determine to what extent this border zone represents a true gradient of collateral flow from center to edge, selective intracoronary (IC) 7-10 μ radioactive micropheres (M) were used to mark the myocardium fed at rest by the anterior descending (LAD) and circumflex arteries (LC). The LAD and LC were separately perfused from the femoral arteries. Peripheral coronary pressure, peak reactive hyperemia, resting flow, and inner/outer wall flow were similar in LAD and LC regions. Passage of ICM to the opposite region was
