8 week old shih-tzu with loud left-sided systolic murmur, no clinical signs reported although I believe there was some pulmonary edema by the end of my exam.

-In the right – sided short axis view of the MPA, I do see turbelence under the bifurcation of the PA but the entire PA is not turbulent.  In the left – sided cranial view, I do see very turbulent continuous flow to the right side of the PA.

-The PA is not enlarged, is that possible and still have a PDA?
-There is mild LA enlargement.  LA:Ao 1.42

-No valvular insufficiencies.

-%FS = 29

-No valvular insufficiencies.

-%FS = 29

-The aortic outflow does not measure increased (1.82).

I will attach some images below.

Can you confirm this as a PDA?  I have found them before but not on patients this young and this is not quite what I usually expect.  If not, what should I consider as alternatives?

Thanks!
