Overview
Coarctation of the aorta is a common malformation. It 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. It is commoner in caucasians with approximately 7 times more cases in caucasians versus asian.
Epidemiology and demographics
Prevalence
- Aortic coarctation is a common congenital heart defect.
- It forms approximately 6-10% of all congenital heart disease cases.
- In live births, it accounts for approximately 5-7% of congenital heart disease in severely ill infants.
Mortality
- The mortality rate of aortic coarctation hinges primarily on the age of surgical intervention to repair the defect. Left untreated, less than 20% of untreated patients reach the age of 50. However, with surgical repair, mortality rates are far less severe.
- If repaired by the age of 14, the mortality rate for 20 years out post-surgery is 9% (a 91% survival rate).
- If repaired later than 14, the mortality rate is 11% (a 79% survival rate).
- In expectant mothers with a coarctation of the aorta, the maternal mortality rate ranges between 3-8%. Even with repair, there is a risk of developing complications during pregnancy.
Race
- Demographically, aortic coarctation has a certain link to specific races.
- It is more common in Caucasians, with approximately 7 times more cases in Caucasians versus Asian.
- The incidence has also been noted, in some populations, to be lower in Native American races than Caucasians.
Gender
- 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.
Genetics
- 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 associated conditions
Cardiac
- Bicuspid aortic valve (associated to 30-40% of all cases)
- Ventricular septal defect
- Patent ductus arteriosus
- Mitral stenosis
- Aortic valve stenosis
- Aortic hypoplasia
Non-cardiac
- Intracerebral aneurysm
