Q. Haemodynamics of Tricuspid regurgitation?

Right Atrial pressure tracing shows a prominent ‘v' wave and these cannot be appreciated in a patient with atrial fibrillation. RV angiography is never done to diagnose or assess severity of tricuspid regurgitation.

Natural History

Prognosis of the tricuspid regurgitation depends upon underlying cause, as most of the time tricuspid regurgitation is functional or associated with other valvular lesions. In - patients with severe mitral stenosis it is an independent predictor of poor late outcome. The 4 year survival rates for mild TR is 99 per cent, 90 per cent for moderate and 69 per cent for sever tricuspid regurgitation. In long term patients with severe tricuspid regurgitation develop signs and symptoms of systemic venous congestion and low output state.
