Overview
Coarctation occurs in about 7% of patients with congenital heart defects. It is more common in males than females with a ratio of 2:1. Up to 25% of patients with Turner syndrome have coarctation of the aorta.
Epidemiology and demographics
Aortic coarctation is a common congenital heart defect and is found in 6-8% of all congenital heart disease patients. It is more common in males than females with a ratio of 2:1 and a prevalence of 2-5 times occurring more frequently in males than females. Aortic coarctation, like many congenital heart diseases, is more common in patients with other genetic conditions. As many as 10-25% of patients with Turner syndrome have an accompanying coarctation of the aorta.
Other accompanying conditions, that increase the likelihood of a coarctation of the aorta, include:
- Ventricular septal defect
- Patent ductus arteriosus
- Mitral valve stenosis
- Aortic valve stenosis
- Bicuspid aortic valve - associated to 30-40% of all cases
