Tricuspid regurgitation
A free high-yield preview for the UKMLA Applied Knowledge Test, covering how to recognise this condition. The full SA Note notes add investigations, management and complications, with practice questions on this topic.
Key high-yield points
- Tricuspid valve fails to close during systole → blood leaks from RV into RA
- Secondary (functional) TR accounts for ~80% of significant cases - structurally normal valve fails to coapt due to RV dilation and annular dilatation
- Primary TR - structural valve disease (infective endocarditis, rheumatic, carcinoid)
- Mild TR detectable in up to 65-85% of normal individuals on echo - often a normal variant
