An isolated tricuspidaalklepstenose is extremely rare in adulthood. Almost always there is a combination with a more or less serious tricuspidaalklepinsufficiëntie. When a mitral valve stenosis in old age the cause is almost always a previously created rheumatic fever. In 10% of the patients, also, there appeared to be a tricuspidaalklepstenose. Dooming the valve leaflets is always an expression of a tricuspidaalklepstenose. For assessing the severity of a tricuspidaalklepstenose are no objective criteria exist, however it is important to realize that the pressure differences tricuspidaalklepstenose be less. At a mean gradient of 5 or greater may also be a serious tricuspidaalklepstenose be. The peak gradient is high, both in patients with a severe stenosis without TI as in patients with severe TS with low TI. The deceleration time will be obvious differences. | An isolated tricuspidaalklepstenose is extremely rare in adulthood.

==Insufficiency== | |||
Tricuspid insufficiency (TI) is most common on the basis of RA or RV dilatation. Also, there may be a failure occur in inferior infarction (proximal RCA stenosis). A tricuspid insufficiency rarely caused by damage to the valve itself is created. Typically, there is a functional TI, which is the result of the RV and dilatation of the annulus. | |||

The symptoms of TI are due to decompensation right : peripheral edema , ascites , pleural effusion , an enlarged liver and / or spleen , increased CVD and often poor appetite , sometimes with cachexia and malnutrition as a result. In addition, there is generally expressions of forward failure: exercise-induced shortness of breath, fatigue , cold fingers or toes . | |||
As a tricuspid insufficiency almost always the result of an underlying disease , treatment is aimed at eliminating the underlying cause . Sometimes a repair of tricuspid valve is provided, this usually consists of a tricuspidaalklepplastiek . | |||
