Insights
Familial hypercholesterolemia (FH) can cause severe aortic stenosis, a rare complication. This case highlights aortic valve replacement as a treatment for FH patients with valvular and supravalvular aortic stenosis.
Area of Science:
- Cardiology
- Genetics
- Vascular Biology
Background:
- Familial hypercholesterolemia (FH) is an inherited disorder causing high LDL-cholesterol and premature atherosclerosis.
- Heterozygous FH (HeFH) presents a significant risk for cardiovascular complications.
- Aortic stenosis is a known, though less common, manifestation of severe hypercholesterolemia.
Observation:
- A 64-year-old woman with HeFH presented with chest pain and dyspnea.
- Coronary angiography showed no significant coronary artery stenosis.
- Severe valvular and supravalvular aortic stenosis of the ascending aorta was identified.
Findings:
- The patient underwent aortic valve replacement for severe aortic stenosis.
- Coronary flow studies revealed functional ischemia and reduced coronary flow reserve.
- This case illustrates a rare complication of HeFH involving aortic valve and supravalvular stenosis.
Implications:
- Aortic valve replacement can be a necessary intervention for FH patients with severe aortic stenosis.
- Early recognition and management of aortic complications in FH are crucial.
- This case expands understanding of the vascular manifestations of familial hypercholesterolemia.
Abstract:
Familial hypercholesterolemia (FH) is an autosomal dominant disorder characterized by a high level of LDL-cholesterol and frequent coronary atherosclerosis. We studied a 64 year old woman with heterozygous (hetero) FH, who showed symptoms of chest pain and dyspnea with no other coronary risk factors than post-menopause and hypercholesterolemia. Although her coronary symptoms didn't reveal significant stenosis on coronary angiography, she had severe aortic valvular and supravalvular stenosis at the ascending aorta, which qualified her for aortic valve replacement. Moreover, a coronary flow study revealed functional ischemia with a reduction of the coronary flow reserve. We report a case of valvular and supravalvular aortic stenosis corrected by aortic valve replacement, a rare complication of hetero FH.
