We report a case of severe aortic valve stenosis in a patient with Tangier disease. A 64-year-old female was diagnosed with Tangier disease on the basis of gene mutation. The serum levels of total cholesterol and high-density lipoprotein were 124 mg/dl and 4.3 mg/dl, respectively. She had a symptom of dyspnea and echocardiography revealed severe aortic valve stenosis with the maximum gradient of 60.5 mmHg. Chest computed tomography showed severe calcification of the ascending aorta and the aortic root. Aortic valve replacement using a bioprosthetic valve was performed. Several reports have been made on coronary artery revascularization in Tangier disease patients, but one on surgical treatment for aortic valve stenosis is extremely rare.
