Atrial septal defect (ASD) is a congenital heart defect in which there is a hole in the wall between the atria, the upper two chambers of the heart.[3] Generally there are no symptoms, though poor ability to exercise and shortness of breath may occur later in life.[2] Complications can include stroke, arrhythmias, pulmonary hypertension, and heart failure.[1]
The cause is generally unknown.[1] Risk factors include certain genetic syndromes such as Down, infection with rubella during pregnancy, and exposure to alcohol or cocaine during pregnancy.[2] While a hole between the upper chambers is normal during early development, it generally closes during pregnancy or shortly after birth.[1] Diagnosis is usually by ultrasound of the heart.[2] An ASD may occur alone or with other heart defects.[4]
Small atrial septal defects (less than 5 mm) usually spontaneously close in childhood.[2] Large defects that do not close spontaneously may require surgery.[2] About 16 per 10,000 live births are affected.[2] Early descriptions are attributed to Leonardo da Vinci (1452-1519).[4]
