A 54-year-old male patient was referred for computed tomography angiography to rule out cardiovascular disease. The examination revealed a single coronary artery originating from the right sinus of Valsalva, extending to the normal left circumflex artery and left anterior descending artery domains. The computed tomography showed only mild coronary sclerosis. The myocardial stress flow on the subsequently performed 13 NH 3 myocardial perfusion positron emission tomography demonstrated a relative stress flow reduction in the distal segments along the monocoronary. In the presented patient without significant coronary disease and a benign course of the monocoronary, the relative inability to increase blood flow during stress in the distal segments of the artery is a remarkable finding.
