In general, coronary steal is defined as a fall in blood flow toward a certain vascular region in favor of another area during arteriolar vasodilatation. The coronary artery fistulae is an unusual abnormality in the general population, but is the most common abnormality of the coronary arteries that are ED: Either the ARTERIES ARE hemodynamically significant, or the ABNORMALITY IS hemodynamically significant. Hemodynamically significant. We experienced a 58-year-old male patient with intermittent chest pain at rest. Coronary angiography showed coronary artery fistulae on the LCX and RCA and retrograde flow from the LAD to LCX. Retrograde flow caused coronary artery steal syndrome on LAD territory. A stress/rest MIBI myocardial scan showed reversible ischemia on the LAD territory. He underwent an operation for the coronary artery fistulae, and has since been doing well without chest pain.
