Single coronary artery with spasm.
A single coronary artery is a rare and potentially serious anomaly. We present the case of a 54-year-old woman with chest pain predominantly at rest. A single coronary artery was demonstrated by 64-row multidetector computed tomography (CT) imaging, which is useful for the diagnosis and classification of coronary anomaly. In our case, no coronary artery stenosis was demonstrated on CT angiographic images, and totally occlusive coronary spasm was confirmed by intracoronary infusion of acetylcholine.
