Overview

Tricuspid stenosis (TS) is characterized by structural changes in the tricuspid valve. The most common cause of tricuspid stenosis (TS) is rheumatic heart disease. Echocardiography is the gold standard test for the diagnosis of tricuspid stenosis which gives tricuspid peak inflow velocity and degree of thickening of tricuspid valve leaflets.

Diagnostic Study of Choice

Study of choice

Echocardiography is the gold standard test for the diagnosis of tricuspid stenosis.

The following result of echocardiography is confirmatory of tricuspid stenosis:^[1]^[2]^[3]
- The degree of thickening of tricuspid valve leaflets
- Calcification of tricuspid valve leaflets
- Limited leaflet mobility of tricuspid valve leaflets
- Reduced separation of the tricuspid valve leaflet tips
- Diastolic doming of the tricuspid valve
- Echocardiography gives the degree of fusion of the commissures and chordae tendineae of the tricuspid valve

Staging of Tricuspid stenosis

Based on the valve anatomy, hemodynamics and consequences tricuspid stenosis can be staged into the following:
