Disseminated multiple ostial stenoses in a young woman presenting as unstable angina

A previously healthy 40-year-old woman presented as unstable angina. She had a family history of stroke as the only cardiovascular risk factor. Her blood pressure on admission was 150/90 mmHg. Laboratory study showed absolutely all negative markers of inflammation, autoimmune disorders, or atherosclerosis. Coronary angiography revealed subtotal ostial stenosis of the right coronary artery (RCA). Additionally, total occlusion of the ostium of the right subclavian artery and severe discrete ostial stenoses of left subclavian, celiac, superior mesenteric, both renal arteries were demonstrated on multidetector computed tomographic and magnetic resonance angiographies. She underwent stent implantation at the culprit lesion of RCA, and the left subclavian and both renal arteries. The fluorine-18-fluorodeoxyglucose positron-emission tomography-computed tomography showed slightly increased glucose metabolism at the proximal left subclavian artery. She is doing very well for 10 months during taking antiplatelet agents only.
