Hello

This is Mika a 2 year old Boston Terrier with a continuous murmur. Regular DVM submitted xrays and EKG to Idexx who reported Rt side enlargement on xrays and normal EKG.They were suspicious of Pulmonic stenosis. They have an appointment scheduled with a cardiologist in 2 weeks but the dog is not doing well so we took a look today.

Hello

This is Mika a 2 year old Boston Terrier with a continuous murmur. Regular DVM submitted xrays and EKG to Idexx who reported Rt side enlargement on xrays and normal EKG.They were suspicious of Pulmonic stenosis. They have an appointment scheduled with a cardiologist in 2 weeks but the dog is not doing well so we took a look today.

On US the Rt heart is markedly enlarged and there appears to be an atrial septal defect seen in multiple views. I can actually see it better in short-axis but I am posting the long axis as I believe it is the traditional view. So I was hoping for confirmation on that!

As well there is a hyperechoic oval mass in the outflow tract of the Rt ventricle. There is no smoke but I am wondering if this is a blood clot or a mass?? 

I did not see a ventricula septal defect and CW doppler shows a regurgitant jet in Rt short axis from the TR valve towards the transcucer around 4m/s. Any medications we can give (i.e. vasodialator to reduce afterload?) while waiting for referral.

Thanks. Brent.
