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
-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!

PA is big even deep so right
PA is big even deep so right sided overcirculaiton. Your CF looks like its in the PV area and that spectral doppler looks like PI but images are dark and cant really say.
You would need to put the CF and CV in the deep PA after the PV and before the bifurcation and should get a holosystolic turbulent flow usually around 5-6 m/sec as long reversal isnt occurring.
Here are some PDAs from the sonopath search
