A 50‐year‐old woman with chest pain and an exercise thallium‐201 scintigram positive for focal ischemia was found on coronary arteriography to have a heretofore unreported variant of single left coronary artery with the right coronary artery originating as a branch from the first septal perforator. Proximally, the aberrent vessel coursed through the ventricular septum at the level of the right ventricular outflow tract. A conus artery was absent and this is a possible basis for the focal basal ventricular ischemia and the patient's symptoms.
