Defects Causing An Obstruction to Blood Flow 

A narrowing that causes an obstruction to blood flow is called stenosis.  A complete  obstructions to blood flow (no flow) is called atresia. 

Pulmonary Stenosis: The Pulmonary valve allows blood to flow from the right ventricle to the lungs.  Stenosis can occur at the level of the valve or directly below it (subpulmonary Stenosis).  For pulmonary valve Stenosis, a "valvotomy" is performed, which means surgically opening the valve, to relieve the obstruction.  For subpulmonic Stenosis, the obstructive tissue below the valve is removed.  Both of these operations are performed through a midline sternotomy incision.
