An atrial septal defect (ASD) is a congenital heart defect characterized by an abnormal opening between the two upper chambers of the heart, causing abnormal blood flow through the heart. Often, infants who have atrial septal defects do not have symptoms. Some small atrial septal defects close on their own during infancy.
Anyone who has ever been diagnosed with and/or treated for atrial septal defect should have lifelong care from a cardiologist who specializes in congenital heart defects. The Ohio State University Medical Center provides this care from birth to adulthood. We partner with Nationwide Children’s Hospital to provide the resources necessary for the care of adult congenital cardiac patients through the Columbus Ohio Adult Congenital Heart Disease Program (COACH).
The COACH program focuses on:
- Adults with congenital heart disease (CHD)
- Pulmonary hypertension
- Cardiovascular connective tissue disorders
- Pregnancy in women with heart disease
- Transition of adolescents with CHD into adult congenital heart disease (ACHD) care
- Training of future ACHD providers
Why Choose The Ohio State University Wexner Medical Center?
Ohio State’s Wexner Medical Center offers a team approach to CHD, which means each patient is evaluated by an Adult Congenital Heart Disease (ACHD) specialist, and when appropriate, a cardiac surgeon, an imaging specialist and an interventional cardiologist with training in CHD. This integrated approach means that each patient’s disease is treated individually, with that particular patient’s needs and physical condition in mind.
What Is An Atrial Septal Defect?
If you have an atrial septal defect, blood flows abnormally between the right and left chambers of your heart due to an opening in the wall that separates the two sides. If the defect is large, a larger-than-normal amount of oxygen-rich blood leaks from the left side of the heart to the right side. The blood is pumped to the lungs, although it is already refreshed with oxygen. This can overfill your lungs and cause an increased workload for your heart, causing the right side of the heart to enlarge and weaken and blood pressure in the lungs to increase.
Symptoms of atrial septal defects include:
- Shortness of breath
- Heart murmur
- Heart palpitations
- Lung infections such as pneumonia and bronchitis
- Swelling of the abdomen or lower extremities
- Bluish skin color
Some atrial septal defects require surgical repair. Others can be treated with less invasive cardiac catheterization procedures.
What Causes Atrial Septal Defect?
Atrial septal defects occur during fetal development, and their cause is not known. Genetics may play a role in some cases. If heart defects run in your family, you may wish to consult with a genetic counselor who may recommend genetic testing.
