The tricuspid valve, ensures that there is no backflow of blood from the right ventricle to the right atrium. The tricuspid valve is like the Latin name indicates consists of three leaflets: the septal (S), the anterior (A) and posterior (P) leaflet, whose anterior leaflet is the largest. The tricuspid valve, distinguishes itself not only by the number of valve leaflets of the mitral valve, but also by the manner of attachment. The chordae of the mitral valve attached to two papillary cups which the tricuspid valve attached to a lot more muscular and cups directly to the septum. The valve is located slightly to the apex than the mitral valve.<cite>1</cite> | The tricuspid valve, ensures that there is no backflow of blood from the right ventricle to the right atrium.

Also, there may occur failure in inferior infarction (proximal RCA stenosis). A tricuspid insufficiency rarely is caused by damage to the valve itself. 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 | The symptoms of TI are due to the decompensated right heart failure: 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 manifestations of forward failure: exercise-induced shortness of breath, fatigue , cold fingers or toes . | ||
