Atrial septal defect (ASD) is a congenital heart defect in which blood flows between the atria (upper chambers) of the heart. Normally, the atria are separated by a dividing wall, the interatrial septum.
An atrial septal defect (ASD) allows freshly oxygenated blood to flow from the left upper chamber of the heart (left atrium) into the right upper chamber of the heart (right atrium). There, it mixes with deoxygenated blood and is pumped to the lungs, even though it's already refreshed with oxygen.
May 01, 2017 Atrial septal defect (ASD) is one of the more commonly recognized congenital cardiac anomalies presenting in adulthood. Atrial septal defect is
An atrial septal defect (ASD) Atrial septal defects are the third most common type of congenital heart defect, and among adults, they are the most common.
If there is a hole in the atrial septum, it is called an atrial septal defect (ASD). Some of the blood that should flow into the left ventricle (or lower pumping chamber) from the left atrium now flows into the right atrium through the ASD.
How can the answer be improved?
Atrial septal defect (ASD) is the most common congenital lesion in adults after bicuspid aortic valve. Although the defect often causes no symptoms until adulthood
The atrial septal defect (ASD) is the most common congenital heart defect encountered in adults, accounting for up to 15 of all adult CHD (Fig. 1). It results from the failure of proper embryologic development of the atrial septum.
