Tricuspid stenosis

Stenosis of the tricuspid valve is uncommon. Where it occurs, it is frequently rheumatic in origin and thus associated with other valve disease. Other causes include carcinoid and drug-induced valve disease. Echocardiography is the primary form of assessment, and while there are no standard criteria for stenosis, 2d assessment of morphology and transtricuspid gradient of >5mmHg is suggestive of tricuspid stenosis. Interventional treatment, where required, is typically performed with bioprosthetic valves due to high rates of mechanical valve thrombosis.

Symptoms and will typically be those of right heart failure and venous congestion, while signs will include a raised JVP, peripheral oedema and a systolic murmur heard loudest at the left upper sternal edge on inspiration.
