Suspect cardiac mass


  • 7 yr old mn Shih Tzu x presented in July with history of cardiomegaly and tx for heart failure at the emergency clinic
  • Echocardiogram shows pericardial effusion with no visible masses
  • Pericardiocentesis was performed and the dog has done well ever since
  • Follow up echocardiogram now shows a possible RV mass on left parasternal transverse PA views.  Color flow Dopper is normal.
  • If I change the angle, I can make it go away, but still suspect that it is real and not RV myocardium.
  • What are your thoughts?

    Hi!

    unfortunately, the clips are really short (not even a single cardiac cycle) – could you add some longer videos?

    Thanks!

    • Sorry Peter.  I just realized

      Sorry Peter.  I just realized none of the clips recorded correctly for this study.  I did scan the dog 2 months ago (2 weeks post pericarciocentesis) and I have now added those clips to the original post.  I will also add some more stills from the most recent study.  I am trying to figure out if there is a mass in the right ventricle or if I am picking up normal RV trabeculae muscle.  I am only seeing this on transverse parsternal views.  Thank you!

    Hi!

    Thank you for posting the additional videos – they are longer 😉

    To me it seems rather like RV myocardium based on echotexture – but I could be wrong…

    Sorry that I can’t help further here…

    Best wishes,
