Alkaptonuria is rare genetic disorder of tyrosine metabolism manifesting with signs of tissue pigmentation, dark urine, and ochronotic arthropathies. Commonly undiscovered by late adulthood, alkaptonuria can manifest as cardiac ochronosis with cardiovascular disorders such as valvulopathies, but rarely coronary artery disease. This case report describes 2 patients with aortic stenosis and coronary artery disease in whom alkaptonuria was diagnosed during open heart surgery.

Lipid-lowering therapy (LLT) is effective in preventing CAD but is underutilized in younger patients. The reasons for and consequences of this underutilization are not fully understood.
