Colour Doppler echocardiography is the mainstay in the assessment of moderate to severe tricuspid regurgitation and includes the following.
anomalies/linked shackles/large joint defects.
hyperchromatic central jets or eccentric wall impingement jets.
Early peak echocardiography showing a dense/triangular continuous wave signal of regurgitation.
Cardiac catheterisation may be performed if tricuspid regurgitation is severe or if accurate measurement of pulmonary artery pressure is required prior to planned surgery.
