Overview
Atrial septal defects are the most common form of congenital heart disease, accounting for 20-40% of all congenital heart disease cases in adults. Atrial septal defects can be classified into : ostium secundum, ostium primum, and sinus venosus and common or single atrium defects. Collectively, atrial septal defects account for 10% of all congenital heart disease. Infants and adolescent patients may be asymptomatic until later in life. By 40 years of age, approximately 90% of untreated atrial septal defect patients will experience an onset of symptoms.
Epidemiology and demographics
Epidemiology and demographics of different types of atrial septal defects
- There are four major types of atrial septal defects, ostium secundum, ostium primum, and sinus venosus, single atrium
- The ostium secundum defect is the most common type of atrial septal defect. It accounts for 7% of all congenital heart defects and 30-40% of all congenital heart disease in patients aged 40 or older.
- The ostium primum defect is the second most common type of atrial septal defect. It accounts for 15-20% of all atrial septal defects. This particular form of atrial septal defect is also categorized as an atrioventricular septal defect and is associated with mitral valve abnormalities.
- The sinus venosus defect is the third most common form of atrial septal defect. It accounts for 5-10% of all atrial septal defects. It is commonly associated with anomalous connection of the right-sided pulmonary veins and often requires additional imaging tests in diagnosis.
- Another form of inter-atrial communication is [Patent foramen ovales. They are not atrial septal defects as no septal tissue is missing. (PFOs) are quite common (appearing in 10 - 20% of adults) but are asymptomatic and therefore undiagnosed.
Pediatrics
- As a group, atrial septal defects (ASDs) are detected in 1 child per 1500 live births.
- It accounts for 10% of all congenital heart disease.
Adults
- ASDs make up 20-40% of all congenital heart disease that is seen in adults and are the most common form of congenital heart defect in adults besides bicuspid aortic valve and mitral valve prolapse.[1]
Sex
- In general, atrial septal defect shows a female preponderance, with a female-to-male ratio of 2:1.[2]
Age
- By 40 years of age, approximately 90% of untreated atrial septal defect patients will experience an onset of symptoms.
- Prior to 40, patients may be entirely asymptomatic and live without complication.
