Atrial septal defect (ASD) is a congenital heart defect in which there is a hole in the wall (septum) that separates the two upper chambers of the heart (the atria). In adults, the risks associated with an ASD can include:
- Stroke: The risk of stroke is increased in adults with ASD due to the potential for blood clots to form in the heart and travel to the brain.
- Pulmonary hypertension: The increased flow of blood to the lungs caused by an ASD can lead to high blood pressure in the lung vessels, which can cause shortness of breath and fatigue.
- Heart failure: The increased flow of blood through the hole in the septum can put a strain on the heart and lead to heart failure over time.
- Atrial arrhythmias: Adults with ASD may be at an increased risk of developing abnormal heart rhythms, such as atrial fibrillation, which can lead to palpitations, chest pain and shortness of breath.
- Endocarditis: The increased blood flow through the hole in the septum can also increase the risk of bacterial endocarditis, an infection of the heart's inner lining.
- Eisenmenger syndrome: In some cases, the increased blood flow through the hole in the septum can cause changes to the pulmonary vessels, leading to a condition called Eisenmenger syndrome. This can cause severe pulmonary hypertension and can be life-threatening.
It is important to work with a healthcare provider to monitor for these risks and to consider treatment options, such as surgery or device closure, which may be appropriate for reducing the risks associated with an ASD.
