SAS in a Whippet

  • 6 month old FE Whippet with murmur, no clinical symptoms
  • Moderate mitral and tricuspid regurgitation, suspect valvular dysplasia, also moderate subaortic stenosis (59mmHg)
  • There does not appear to be secondary remodelling except for right side of septum on m-mode view?
  • Do you think this interpretation is correct and what is the prognosis? I 
  • I suspect that the subaortic stenosis will potentially worsen the mitral regurgitation and lead to progressive disease with risk of left sided congestive heart failure?

    • I have recommended repeat scan in 6 months
    • Any comments welcome!

  1. Hi!
    Some degree of mitral

    Hi!

    Some degree of mitral dysplasia is frequently associated with SAS. And it causes a so-called afterload-mismatch (high afterload by LVOT, low afterload through mitral valve. This worsens prognosis because there is more stress on the mitral valve, as you said. Still, I would never be sure in these guys. Sometimes you don’t find much of a change over the years. 

    A re-scan in 6 months is completely ok
