Would love help understanding anatomy ultrasound results

We have spoken with our midwife and we are getting referred for a fetal echocardiogram. Just received the results from our anatomy ultrasound (done at 20w4d) but having a hard time understanding what this could potentially mean and I am spiraling.

“Heart: Cardiac orientation was normal. The interventricular septum (IVS), ventricular outflow tracts and three vessel view were seen. Extended views: Aortic arch was seen and ductal arch was seen. IVC/SVC was seen.

The 4 chambered heart view, posterior to the left atrium there may be some atypical vessels that appear to be separate from the pulmonary veins. The descending aorta is not clearly seen in cross-section. These findings may be technical.”

And then in the “impressions” section it says:

“In the 4 chambered heart view there may be an atypical vessel posterior to the left atrium. See above description. Recommend fetal echocardiogram.

There is a left ventricular echogenic focus. Soft markers: echogenic intracardiac focus”

Would appreciate any insight. Hoping that the fetal echocardiogram gets booked soon.
