In severe cases, however, this condition can lead to a variety of symptoms, like chest pain, dizziness or fainting, and heart failure, particularly in younger infants. A heart murmur is the most common signof this defect. </p><p>An electrocardiogram and echocardiogram are used to make a diagnosis. In mild cases, children with aortic stenosis do not need treatment. However, they do need to receive repeat medical checkups with echocardiograms because sometimes the narrowing gets worse as the child grows older. </p><h2>How is aortic stenosis treated?</h2><p>Cardiac catheterization is often used to treat aortic stenosis. The narrowed valve is stretched open through a procedure called balloon dilation valvuloplasty. This may relieve the narrowing, but the valve leaflets may remain stiff and are unable to close properly. This means there may be leakage of blood backwards through the valve, called regurgitation. </p><p>Sometimes open heart surgeryto cut open the leaflets of the valve so they open better is needed. This is called a surgical valvotomy. Later, surgery may be needed to replace the valve if it is very small or leaky. This is called aortic valve replacement. </p><h2>What is the long-term outlook for children with aortic stenosis?</h2><p>Children with aortic stenosis will need to be seen by a cardiologist for their whole lives, since the condition can worsen over time, even after surgery. </p>Aortic stenosis
