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 ...
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 ...
Pulmonary valve defects resulting in tricuspid regurgitation, a common effect of pulmonary stenosis, can cause this increase in muscle mass. [5] Atrial septal defect An atrial septal defect is a hole in the septum that divides the right and left atria (the upper two chambers) of the heart. In the heart of a developing fetus, there are several ...
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]
Fetal abnormalities are conditions that affect a fetus or embryo, are able to be diagnosed prenatally, and may be fatal or cause disease after birth.They may include aneuploidies, structural abnormalities, or neoplasms.
Atrioventricular septal defect (AVSD) is an uncommon congenital heart condition characterized by faulty development of the heart's septa and valves. [88] [12] Congestive heart failure is common in infants with the entire version of the condition. [88] [12] Fluid builds up in other parts of the body, particularly the lungs.
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 ...
3) Abnormalities of the mitral and/or tricuspid valves. [ 1 ] [ 2 ] AVCD is caused by an abnormal or inadequate fusion of the superior and inferior endocardial cushions with the mid portion of the atrial septum and the muscular portion of the ventricular septum . [ 3 ]
