There are many ways you can help children and their families get the care they need.
Boston Children's Hospital's cardiologists, cardiac surgeons and nurses, cardiac imaging professionals and other clinicians have years of expertise in treating all types of heart defects and heart disease, with specialized understanding of problems like aortic valve stenosis that affect the valves of the heart.
Our team treats every stage of aortic valve stenosis in children, adolescents and adults, as well as babies in utero. We use minimally invasive techniques—medical and surgical procedures that use small incisions and miniaturized cameras and tools—whenever we can, and are committed to repairing a child's own valve rather than resorting to an entire valve replacement whenever possible. Boston Children's Interventional Catheterization Program has made great strides in allowing children to keep their own heart valves for as long as possible during treatment.
Your child's exact treatment plan will be determined by his age, the extent of narrowing in his aortic valve, his overall health and your and your family's preferences.
Children with mild to moderate aortic valve stenosis may not require any treatment other than routine monitoring in the short term.
Your child's cardiologist will regularly evaluate your child for any sign of further narrowing in the aortic valve and related complications. Most often, routine monitoring will involve physical examinations and echocardiograms.
Medication is not a cure for aortic valve stenosis, but can be helpful in managing specific symptoms. In some cases, your child's clinician may prescribe medication to:
A child with aortic valve stenosis may also need to periodically take antibiotics in order to prevent an infection called bacterial endocarditis, even if his aortic valve has been surgically replaced. Bacterial endocarditis can cause serious damage to the inner lining of the heart and its valves. You should always let medical personnel know about your child's aortic valve stenosis before making arrangements for a medical procedure, even if the procedure seems minor or unrelated to your child's cardiac care.
If your child has aortic valve stenosis, but no other cardiac problems, he probably will not need antibiotics before a routine dental procedure (for example, a teeth-cleaning).

Boston Children's has a comprehensive program dedicated to interventional catheterization, the use of a thin tube called a catheter that is threaded from a vein or artery into the heart. This catheter can be used to fix holes in the heart, open narrowed passageways (like the aortic valve) and create new passageways.
Recognizing the benefits of this minimally invasive treatment—less discomfort, shorter recovery periods and the use of the child's own valve, which will grow with the child after the procedure—Boston Children's considers interventional catheterization the preferred frontline approach to aortic valve stenosis.
The most common interventional catheterization procedure used to treat aortic valve stenosis is balloon dilation, also known as balloon valvuloplasty. With a child is under sedation, a small, flexible catheter is inserted into a blood vessel, most often in the groin. Using tiny, highly precise cameras and tools, clinicians guide the catheter up into the inside of the heart and across the aortic valve. A deflated balloon at the tip of the catheter is inflated once the tube is in place, and this balloon stretches the aortic valve open, reversing the problematic narrowing.
For children with severe aortic valve stenosis, balloon valvuloplasty may not be able to adequately fix the narrowed valve and restore healthy heart function. In other cases, as the child grows, an aortic valve that was previously treated successfully with one or more balloon dilation procedures begins to narrow again, adding strain to the heart and affecting blood flow throughout the body. Replacement of the aortic valve is the next step in treatment for these children.
During this procedure, cardiac surgeons will remove the damaged aortic valve and replace it with either
Both types of valve replacement surgery have an excellent success rate and a low incidence of complications. Children who undergo either type of valve replacement procedure are likely to enjoy normal, healthy adult lives with minimal to no restrictions on playing sports or engaging in other strenuous activities.
Most children need to stay in the hospital for a week to 10 days after valve replacement surgery, and will need another three to six weeks of rest at home before returning to their normal daily activities.
Children with implanted valves—just like children with aortic valve stenosis, in general—can be more susceptible to bacteria entering the bloodstream. The bacteria can cause a serious infection called bacterial endocarditis. As a result, these children might need a regimen of antibiotics before undergoing some medical procedures. If your child has undergone valve replacement surgery, you should always inform medical personnel of your child's condition before arranging for any procedure.
It is likely that your child will need another valve replacement surgery within 20 years as the donor valve ages.
When your child is living with aortic valve stenosis, your family may have many concerns, worries and questions. Not only are you focused on meeting all of your child's medical needs; you are also grappling with a significant emotional and psychological toll that can affect every member of the family.
