Tricuspid regurgitation

A free high-yield preview for the UKMLA Applied Knowledge Test. Below are the key points to recognise tricuspid regurgitation — the full SA Note notes add investigations, management, complications and 10 practice questions.

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
