Abstract
Dogs with 70% stenosis of the left circumflex coronary artery showed a reduction of myocardial blood flow with a minimal impairment of left ventricular wall motion. Eighty to ninety percent stenosis produced a marked reduction of flow and wall motion, and ST elevation close to 100% occlusion, but delayed antegrade run-off was found. The effectiveness of collaterals to protect against left ventricular dysfunction was supported.
