It can be either between from one coronary territory to another or from coronary territory to a non coronary territory. Different such scenarios can be found in literature.<\/p>\n<p>Abnormal stress test due to large anomalous vessels supplying a large left atrial myxoma producing CS has been reported [1]. Symptoms and abnormal stress test response resolved after resection of the tumour and ligation of the abnormal vessels.<\/p>\n<p>Another situation is CS into a coronary cameral fistula connecting a coronary artery branch to the left ventricle [2]. Rupture of a coronary artery aneurysm into the right atrium in a patient with systemic lupus erythematosus and sepsis resulted in inferior wall myocardial infarction due to CS [3]. Angina and positive stress test occurred in a patient with a fistula connecting left anterior descending coronary artery to left superior pulmonary vein [4].<\/p>\n<p>CS and ischemia can occur due to a patent side branch in left internal mammary artery (LIMA) to coronary artery bypass graft (CABG) [5]. Coil embolization of the LIMA side branch produced relief of CS and ischemia.<\/p>\n<p>Multiple coronary micro fistulae into the ventricles due to persistent Thebesian veins is another rare cause of coronary steal [6]. These cases are not amenable to any surgical measures, but respond to usual antianginal medications other than coronary vasodilators. Coronary vasodilators can theoretically worsen the coronary steal phenomenon.<\/p>\n<p>CS can occur in post CABG patients&nbsp;with a LIMA graft if the subclavian gets occluded. A post CABG patient who had LIMA to left anterior descending coronary artery (LAD) with bilateral subclavian-carotid artery graft occlusion presented with non ST elevation myocardial infarction [7]. The patient was successfully treated with endovascular procedures in the cardiac catheterization laboratory.<\/p>\n<p><span style=\"color: #0000ff;\"><strong>References<\/strong><\/span><\/p>\n<ol>\n<li>Stiver K, Bittenbender P, Whitson BA, Bush CA.
