Subaortic stenosis: Narrowing of the left ventricle of the heart just below the aortic valve through which blood must pass on its way up into the aorta. The narrowing cuts the flow of blood.
Accordingly, what is a subaortic stenosis?
Subaortic stenosis is the second most common form of left ventricular outflow obstruction. It occurs when the flow of blood from the heart's pumping chamber or left ventricle is restricted. This obstruction is in the area of the heart under the aortic valve. There are three types of subaortic stenosis.
What is Supravalvular stenosis?
Supravalvular aortic stenosis is a congenital obstructive narrowing of the aorta just above the aortic valve. It is often associated with other cardiovascular anomalies and is one of the characteristic findings of Williams syndrome. The diagnosis can be made by echocardiography or MRI.
What is Shone's Complex?
Shone's syndrome (also called Shone's complex, Shone's anomaly, or Shone's disease) is a rare congenital heart disease described by Shone in 1963. In the complete form, four left-sided defects are present: Supravalvular mitral membrane (SVMM) Parachute mitral valve. Subaortic stenosis (membranous or muscular)
