SONOGRAPHIC FINDINGS ASSOCIATED WITH ACUTE PULMONARY EMBOLISM

  • RV dilation, defined as RV/LV basal diameter ratio greater than normal and apical blunting of the RV in multiple windows/views. 
    • Normal RV/LV basal diameter ratio is 1/3 to 1/2 
    • Tricuspid Regurgitation may also be present
    • If dilated, the RV should be very thin. If it is thick, this may not be an acute change in right heart pressure. 
  • RV systolic dysfunction, defined as free-wall hypokinesis and/or TAPSE <16 mm. 
  • Flattening or deviation of the interventricular septum toward the LV. 
    • Septal abnormalities will first appear during ventricular diastole. 
    • Also known as the D-sign
  • Dilated IVC in response to elevated RA pressures.
