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 ...
Approximately 40-80 percent of patients with VACTERL association have been reported to have congenital heart disease. [5] The most common heart defects seen with VACTERL association are ventricular septal defect (VSD), atrial septal defects and tetralogy of Fallot. Less common defects are truncus arteriosus and transposition of the great arteries.
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]
The most common heart malformations from genetic or epigenetic problems are: stenosis of the aorta and pulmonary trunk, which is a narrowing of the vessels, atrial and/or ventricular septal defect, tricuspid atresia, and hypoplastic left and right heart syndrome. When an individual has hypoplastic right or left heart syndrome, it means that ...
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 ...
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).
