Because of the incidence of sudden death during athletic performance, competitive sports or other highly exertive activities are not recommended. Low blood pressure (hypotension) may be dangerous for the patient with this abnormality. Therefore, excessive loss of body fluids from dehydration should be avoided. Hot baths and saunas may also pose risks.

Anyone with congenital heart disease, repaired or non-repaired, should consult with their cardiologist about physical activity to review the risks.
