Atrial Septal Defects

What can be done to prevent the condition?

An atrial septal defect is often not preventable. Pregnant women should avoid alcohol. A woman who may get pregnant should make sure all her vaccines are up to date, to lower the risk of infection in the womb.

What are the long-term effects of the condition?

The effects of an ASD depend on the size and location of the defect. Breathing problems and congestive heart failure can occur with serious unrepaired defects. An ASD may also cause arrhythmias and infections of the heart or lungs. The ASD may occur together with other congenital heart defects, such as ventricular septal defect. This combination can worsen the effects of the defect.

What are the risks to others?

An ASD is not contagious and poses no risk to others.
