Core Tip

Core Tip: The incidence of coronary artery anomalies is as low as 1%-2% in the general population, even when the various types are combined. Among these, the R-1 subtype in a single coronary artery is extremely rare. In this case report by Zhou et al, emission computed tomography showed that ischemia occurred in an area where the coronary artery was not visible to the naked eye. Meticulous follow-up is crucial because sudden death may occur owing to a single coronary artery. Furthermore, atherosclerosis prevention is important because percutaneous coronary intervention could pose a high risk when necessary for such anomaly.
