Trans-Esophageal Echocardiography Views for Tricuspid Valve Imaging
Tricuspid regurgitation Functional tricuspid regurgitation (TR) can also be observed in a variety of diseases producing pulmonary hypertension and/or right ventricular (RV) dysfunction [Figure 5] The most important characteristics of functional TR are its variability in a given patient. Two-dimensional findings of tricuspid regurgitation [Figure 6]. Two dimensional echocardiography Leaflets: Thickened, prolapse, flail, non coapting. Annulus: Tricuspid annulus [Figure 8] dilated when >36 mm septolateral dimension (4C view) or 2.1 cm/m 2 Color Doppler: Turbulent retrograde flow, mosaic or red; vena contracta [Figure 7], proximal isovelocity surface area radius
Figure 7: Measurement of vena contracta on color Doppler in RV inflow-outflow view Click here to view Pulsed-wave: Increased E wave velocity >1 m/s, hepatic vein flow reversal View to measure RV systolic pressure is RV inflow - outflow view and pulmonary artery systolic pressure in not an index for TR severity [Figure 9].

Tricuspid stenosis Two-dimensional findings Thickened leaflets, decreased mobility, tethered tips, right atrial enlarged, dilated inferior vena cava [Figure 10]. Color Doppler - turbulent flow Continuous wave Doppler - peak E velocity >1 m/s. Grading of tricuspid stenosis Mean gradient < 2mm Hg - Mild stenosis Mean gradient 2-6mm Hg - Moderate stenosis Mean gradient >6 mm Hg - Severe stenosis. Tricuspid stenosis on three-dimensional trans-esophageal echocardiography [Figure 11].
