Most congenital heart defects are not associated with other diseases. [3] A complication of CHD is heart failure. [2] Congenital heart defects are the most common birth defect. [3] [11] In 2015, they were present in 48.9 million people globally. [8] They affect between 4 and 75 per 1,000 live births, depending upon how they are diagnosed.
CDK13-related disorder, also known as congenital heart defects, dysmorphic facial features and intellectual developmental disorder (CHDFIDD), is a very rare autosomal dominant genetic condition characterised by congenital heart defects, intellectual disability and characteristic facial features.
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 happens when part of your heart doesn’t develop properly from birth. The underlying cause often isn’t clear, but risk factors include: Down’s syndrome.
Noonan syndrome is the second most common syndromic cause of congenital heart disease. 50-70% of individuals with NS are born with some form of congenital heart defect, with pulmonary valvular stenosis being the most common (50–60%). [9]
DiGeorge syndrome, also known as 22q11.2 deletion syndrome, is a syndrome caused by a microdeletion on the long arm of chromosome 22. [7] While the symptoms can vary, they often include congenital heart problems, specific facial features, frequent infections, developmental disability, intellectual disability and cleft palate. [7]
Cor triatriatum (or triatrial heart) [1] is a congenital heart defect where the left atrium (cor triatriatum sinistrum) or right atrium (cor triatriatum dextrum) is subdivided by a thin membrane, resulting in three atrial chambers (hence the name).
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 ...
