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. It is common in patients with a congenital atrial septal aneurysm ASA. After PFO closure the atria normally are separated by a dividing wall, the interatrial septum. If this septum is defective or absent, then oxygen -rich blood can flow directly from the left side of the heart to mix with the oxygen-poor blood in the right side of the heart; or the opposite, depending on whether the left or right atrium has the higher blood pressure. This can lead to lower-than-normal oxygen levels in the arterial blood that supplies the brain, organs, and tissues.

Professional Reference articles are designed for health professionals to use. You may find the Atrial Septal Defect article more useful, or one of our other health articles. Atrial septal defect ASD is a type of heart defect which allows communication between the left and right side of the heart.
These interatrial communications can result from defects in the interatrial septum but also from defects in the atrial connections of the systemic or pulmonary veins sinus venosus or coronary sinus defects.
Patent foramen ovale is a normal communication in fetal life and is commonly seen after birth. It needs to be differentiated from ASDs. J Am Coll Cardiol.

Atrioventricular Septal Defect
Atrioventricular AV septal defect consists of an ostium primum type atrial septal defect and a common AV valve, with or without an associated inlet AV septal type ventricular septal defect VSD. These defects result from maldevelopment of the endocardial cushions. If there is a large VSD component or significant AV valve regurgitation, patients often have signs of heart failure, including dyspnea with feeding, poor growth, tachypnea, and diaphoresis. Heart murmurs, tachypnea, tachycardia, and hepatomegaly are common. Diagnosis is by echocardiography. Treatment is surgical repair for all but the smallest defects. An AV septal defect may be.
Atrial septal defect
This defect allows oxygen-rich blood to leak into the oxygen-poor blood chambers in the heart. ASD is a defect in the septum between the heart's two upper chambers atria. The septum is a wall that separates the heart's left and right sides. Every child is born with an opening between the upper heart chambers. It's a normal fetal opening that allows blood to detour away from the lungs before birth.
