Pulmonary stenosis

Stenosis of the pulmonary valve is another uncommon disease and, where seen, is mostly congenital in nature. Significant stenosis can be seen as part of the tetralogy of Fallot, but mid stenosis is typically asymptomatic and has a long-term benign prognosis. Where needed, interventional treatment is typically with percutaneous balloon valvuloplasty and surgical intervention and valve replacement is reserved only for those cases that have failed percutaneous treatment or otherwise have a contraindication.
