There are no exercise restrictions for patients with mild stenosis, or for those in whom treatment has reduced the obstruction to acceptably low levels. If the stenosis is moderate to severe, then treatment should be obtained before pursuing unrestricted physical activity or engaging in contact sports. Regular testing is necessary to ensure that the obstruction remains low.

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