Coronary artery bypass graft in a 10-year-old child with familial hypercholesterolemia

Abstract

Homozygous familial hypercholesterolemia (HoFH) is a result of a defect in low-density lipoprotein (LDL) receptor gene located on the short arm of chromosome 19 which leads to inadequate clearance of lipoproteins from blood circulation. Homozygous and heterozygous types are available. In homozygous types coronary lesions emerge due to early atherosclerosis in the first decade of life, and untreated patients are lost generally when they are 20 years of age. Our patient was admitted to our outpatient clinic with the complaint of exertional chest pain six months after diagnosis of familial hypercholesterolemia. Coronary angiography was performed because of the patological exercise stress test. Significant coronary artery stenosis was detected. Then the patient successfully underwent coronary bypass grafting. This case is presented to highlight that coronary lesions may develop at an early disease stage of the patients with hyperlipidemia
