==Stenosis==
Stenosis of the pulmonary valve is very rare . Although as with aortic stenosis , the cause may be located above or below the valve , the valve usually is a wrong engineered valve . Which is then deformed dome formation with a small opening .

Tetralogy of Fallot results in a lower concentration of oxygen in the blood by the mixing of oxygen - rich blood and into the ventricles . The obstruction of the pulmonary valve ensures that blood from the right ventricle to the aorta flows through the ventricular septal defect . Usually this syndrome marked by cyanosis of the baby . This disorder was formerly called blue baby syndrome therefore called , but there are also " pink Fallots ", where the obstruction of the pulmonary valve is less severe . These patients are usually detected with an image of heart failure by excessive flow of the pulmonary vascular tree . In rare cases, there is a balanced position , wherein the stenosis is large enough in order to protect ( against over- flow) , and is low enough not to cause too much. Cyanosis pulmonary vascular
Tetralogy of Fallot results in a lower concentration of oxygen in the blood by the mixing of oxygen - rich blood into the ventricles. The obstruction of the pulmonary valve ensures that the blood from the right ventricle to the aorta flows through the ventricular septal defect. Usually this syndrome is marked by cyanosis of the baby. Thus this disorder was formerly called "blue baby syndrome". There are also "pink fallots", where the obstruction of the pulmonary valve is less severe. These patients are usually detected with an image of heart failure by excessive flow of the pulmonary vascular tree. In rare cases, there is a balanced position, wherein the stenosis is large enough in order to protect (against over-flow), and is low enough not to cause too much cyanosis pulmonary vascular.

==Insufficiency==
Pulmonaalinsufficiëntie is a volume load on the RV . Important insufficiency will lead to RV dilation. This volume will load the RV long endure , but will eventually go the RV failure.
