Pulmonic and tricuspid regurgitation

  • 12 year old Shih Tzu with left sided G 5/6 and right sided G 4/6 murmur
  • Slowing down
  • There is myxomatous mitral valve disease with flail leaflet and dilated LV and LA
  • There is increased pulmonic velocity, do you think valve movement is normal? It does not appear thickened or narrowed at annulus. I could not get good colour doppler of this region, not getting good position of MPA

    • The tricuspid regurgitation is consistent with mild pulmonary hypertension which I do not think would be surprising given the left sided changes but I first need to rule out pulmonic stenosis. Right sided chambers look normal to me. 
    • Can you clear this up for me please?

  1. I think this is all

    I think this is all incidental… PHT usually in my experience is not clincal til in the> 3.5-4 m/sec but there is no consensus. i go by volume overload and hepatic vein congestion whether clinical or not.

  2. Thanks Eric. Just from my

    Thanks Eric. Just from my learning point of view, what do you think is causing the mildy increased pulmonic velocity?

  3. Not sure… is that velocity

    Not sure… is that velocity present at multiple angles?? Given the hyperdynamic state with the mv prolapse and la volume overload I wouldnt be surprised by 2 or 2.5 m./sec as an indirect result. Otehrwise minor ps is possible
