Otherwise, surgery usually can be delayed. A child with a severe coarctation should have surgery in early childhood. This prevents problems such as developing high blood pressure as an adult. The normal aortic valve has three flaps, or cusps, that open and close. A bicuspid valve has only two flaps, rather than three.
Treatment depends on how well the valve works.
Subaortic means below the aorta . Subaortic stenosis refers to a narrowing of the left ventricle just below the aortic valve, which blood passes through to go into the aorta. This stenosis limits the flow of blood out of the left ventricle. Treatment depends on the cause and the severity of the narrowing. It can include drugs or surgery.
