Atrial septal defect (ASD) is a congenital heart defect in which blood flows between the atria (upper chambers) of the heart.Some flow is a normal condition both pre-birth and immediately post-birth via the foramen ovale; however, when this does not naturally close after birth it is referred to as a patent (open) foramen ovale (PFO).
The ostium primum atrial septal defect is a defect in the atrial septum at the level of the tricuspid and mitral valves. This is sometimes known as an endocardial cushion defect because it often involves the endocardial cushion, which is the portion of the heart where the atrial septum meets the ventricular septum and the mitral valve meets the tricuspid valve.
An atrial septal defect is a congenital heart defect where the septum between the right and left atrium doesn’t close up all the way and remains open after birth. This causes oxygenated blood to go into pulmonary circulation. One complication from this condition is a paradoxical embolus which crosses from the right to the left side via the ASD.
Atrioventricular septal defect (AVSD) or atrioventricular canal defect (AVCD), also known as "common atrioventricular canal" or "endocardial cushion defect" (ECD), is characterized by a deficiency of the atrioventricular septum of the heart that creates connections between all four of its chambers. It is a very specific combination of 3 defects:
Foramen secundum atrial septal defects are the most common atrial septal defects. This defect can arise as a result of defects of the septum primum and the septum secundum. For the septum primum, the problem can arise as a result of excess resorption of the septum during the process of apoptosis in order to form the foramen secundum.
It is commonly known as both congenital atrial septal defect (ASD) and acquired mitral stenosis (MS). [2] Congenital (at birth) atrial septal defect refers to a hole being in the septum or wall that separates the two atria; this condition is usually seen in fetuses and infants. [3]
A sinus venosus atrial septal defect is a type of atrial septal defect primarily associated with the sinus venosus. They represent 5% of atrial septal defects. [1] They can occur near the superior vena cava or inferior vena cava, but the former are more common. [2] They can be associated with anomalous pulmonary venous connection. [3]
Failure of the septum primum to fuse with the endocardial cushion can lead to an ostium primum atrial septal defect. [1] This is the second most common type of atrial septal defect [2] and is commonly seen in Down syndrome. Typically this defect will cause a shunt to occur from the left atrium to the right atrium.
