Type R1 Single Coronary Artery Without Obstructive Disease

Résumé fourni par la source

Single coronary artery is a congenital anomaly defined by a solitary artery supplying the heart. It may present as angina in the absence of coronary obstruction. A 73-year-old man presented to our institution with chest pain and exertional dyspnea. He was ultimately found to have a single coronary artery arising from the right coronary cusp (type R1). Multimodal imaging, including computed tomography and coronary angiography, revealed no flow-limiting lesions. The patient was medically managed to optimize coronary disease risk and to minimize symptoms. This case underscores the clinical relevance of anatomical coronary variants and the role of imaging in evaluating symptoms in this subset of the population.
