Persistent truncus arteriosus!

Hi everyone!

 

This is a my very first (and only?) and super rare persistent ductus arteriosus (PTA)!

3mo female, no breed, with exercise intolerance and grade III/IV murmur (louder in the left side)

 

What I think I am seeing here:

– Persistent ductus arteriosus with an almost non existent funcional VSD (I’ve googled and searched some books and didn’t find any thing like it!)

– Stenotic RVOT

– Double velocity PTA, high velocity from the RVOT velocity and normal velocity from the LVOT

– Severe hypertrophy of the RV due to the RVOT stenosis (or would you think equalized pressure between ventricles? but TR=140mmHg and MR=100mmHg)

– important thickening (dysplasia) of the septal cuspid of Mitral valve, with associated regurgitation

– PTA has a bicuspid valve (huge ones!)

– I didn’t see the pulmonary artery branches and I don’t have very good views of the PTA, but I’ll rescan this puppy in 1 or 2 weeks just to focus on that.

 

 

Yesterday I scanned my first situs inversus totalis with dextrocardia and today this. I am completely and utterly 100% mind blown.

 

I’d love to hear your thoughts.
