[[Atrial septal defect]]s 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 : [[Atrial septal defect ostium secundum|ostium secundum]], [[Atrial septal defect ostium primum|ostium primum]], and [[Atrial septal defect sinus venosus|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 [[atrial septal defect symptoms|symptoms]].

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. The Centers for Disease Control and Prevention (CDC) estimated that each year about 1,966 babies in the United States are born with an atrial septal defect.[1]Atrial septal defects can be classified into : ostium secundum, ostium primum, sinus venosus, coronary sinus ASDs 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

Prevalence

There are four major types of atrial septal defects, ostium secundum, ostium primum, sinus venosus and coronary sinus type [2]

  • The ostium secundum defect is the commonest type of atrial septal defect. It constitutes 75% of all types 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 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.
  • The coronary sinus ASD is the least common and forms less than 1% of all types of atrial septal defect.
  • Another form of inter-atrial communication is patent foramen ovale. A patent foramen ovale is not an atrial septal defect as no septal tissue is missing. (PFOs) are quite common (appearing in 10 - 20% of adults) but are asymptomatic and therefore undiagnosed.

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.

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

Gender

  • In general, atrial septal defect shows a female preponderance, with a female-to-male ratio of 2:1.[4]
