Hello, I can see why you are concerned, especially if you were a busy, healthy person before Covid. And being unable to consult with your doctor undoubtedly made you worry even more. Sometimes I think it's a bad idea to post results to the patient portal before the doctor sees them and can explain.

Here are some things we do know:
The symptoms you were seeing in April, with the extreme fatigue, brain fog, etc are typical of long Covid. The initial tests all coming back "normal" is very usual after Covid.
We also know, from experience since 2020, that a Covid infection can cause changes in the heart due to inflammation. There is not a lot of study material yet to say whether those things heal or not.

Heart tests like the echocardiogram are just a starting point for the diagnostic process. Statements like "Cannot assess RVSP due to lack of sufficient TR jet." are very typical - it can depend on the skill of the tech, the sensitivity of the machine, the clarity of the image, the position of the patient...

When I had a stress echo last year, there were at least 4 statements like that in the report. I would have been alarmed, but the very comforting assistant in the room explained ahead of time not to be alarmed by any such statements. I also showed the regurgitations, but the cardiologist later explained they were mild, just to be watched, and not the true cause of my shortness of breath - and pointed me back to my pulmonologist.

At this point, I would suggest you take a deep breath, and wait to talk to your doctor. Given all the symptoms you are experiencing, maybe you would like to tak to them about getting into a long Covid program? Will you let me know what the doctor says?
