Overview

The blowing holosystolic murmur of tricuspid regurgitation must be distinguished from mitral regurgitation and a ventricular septal defect.

Differentiating Tricuspid regurgitation from other Diseases

Tricuspid Regurgitation Mitral Regurgitation VSD Constrictive Pericarditis[1]
  • The holosystolic murmur can be best heard over the left third and fourth intercostal spaces and along the sternal border.
  • When the shunt becomes reversed (Eisenmenger's syndrome), the murmur may be absent and S2 can become markedly accentuated and single.
Severe TR has been documented to mimic some hemodynamic findings in constrictive pericarditis, with right heart catheterization demonstrating a constrictive physiology. Echocardiography, CT thorax, and cardiac MRI are useful for ruling out pericardial pathology.
