Tricuspid atresia is a form of congenital heart disease whereby there is a complete absence of the tricuspid valve. [2] Therefore, there is an absence of right atrioventricular connection. [2] This leads to a hypoplastic (undersized) or absent right ventricle. This defect occurs during prenatal development, when the heart does not finish ...
A congenital heart defect (CHD), also known as a congenital heart anomaly, congenital cardiovascular malformation, and congenital heart disease, is a defect in the structure of the heart or great vessels that is present at birth. [7] A congenital heart defect is classed as a cardiovascular disease. [10]
This type of congenital heart defect is associated with patients with Down syndrome (trisomy 21) or heterotaxy syndromes. [ 8 ] 45% of children with Down syndrome have congenital heart disease. Of these, 35–40% have AV septal defects. [ 9 ]
Hypoplastic left heart syndrome (HLHS) is a rare congenital heart defect in which the left side of the heart is severely underdeveloped and incapable of supporting the systemic circulation. [2] It is estimated to account for 2-3% of all congenital heart disease. [ 3 ]
Ebstein's anomaly is a congenital heart defect in which the septal and posterior leaflets of the tricuspid valve are displaced downwards towards the apex of the right ventricle of the heart. [1] EA has great anatomical heterogeneity that generates a wide spectrum of clinical features at presentation and is complicated by the fact that the ...

Congenital heart disease, particularly VSDs, is the number one cause of death for children with Down syndrome ages birth to two. [ 7 ] A VSD can also form a few days after a myocardial infarction [ 8 ] (heart attack) due to mechanical tearing of the septal wall, before scar tissue forms, when macrophages start remodeling the dead heart tissue.
Supravalvular aortic stenosis is a congenital obstructive narrowing of the aorta just above the aortic valve and is the least common type of aortic stenosis. It is often associated with other cardiovascular anomalies and is one of the characteristic findings of Williams syndrome. The diagnosis can be made by echocardiography or MRI.
