Tricuspid valve
Tricuspid stenosis
TS is the narrowing of the tricuspid orifice, leading to the obstruction of blood flow from the right atrium to the right ventricle.
- In most cases, TS is due to rheumatic fever. Other, rare causes include SLE and tumors.
- TS is also usually present.
- The right atrium becomes dilated (eccentric hypetrophy), leading to AF, right-sided HF, and reduced CO.
- Presents with fatigue and cold skin, distended veins in the head and neck, prominent a wave (atrial contraction) in JVP, edema, hepatosplenomegaly, ascites.
Treatment
- Diuretics
- Rarely, valve repair or replacement
Tricuspid regurgitation
TR is the failure of the tricuspid valve to close completely during systole, allowing backflow into the right atrium.
