Atrial septal defect

Atrial septal defect (ASD) is one of the most common types of congenital heart disease, second only to ventricular septal defect. It is formed by the residual patent defect on the atrial septum during embryonic development. The vast majority of atrial septal defects are single hole type, a few are multi hole type, and very few are sieve like. Atrial septal defect accounts for about 15% - 20% of congenital heart disease, and the ratio of men to women is 1.7:1. Because the symptoms of the disease are mild and the signs are not obvious in childhood, a large number of patients are not found until adulthood.
