Purpose To investigate the cardiac computed tomographic (CT) findings and clinical implications of subprosthetic pannus in patients who have undergone aortic valve replacement. Materials and Methods The institutional review board approved this retrospective study, and the need to obtain written...

The incidence of pannus-related prosthetic valve dysfunction is known to be 0.1%–0.6% per patient-year for valves in the aortic position, but pannus is presumed to be higher in frequency than previously reported, as it is found even in asymptomatic patients
so not likely but possible
this aritcle:
Prosthetic valve dysfunction at aortic position is commonly caused by pannus formation. The exact etiology is not known. It arises from ventricular aspect of the prosthesis encroaching its leaflets causing stenosis or it may remain localized causing left ...

discusses recurrence (which is usually trated with a catheter) but reading it would make it clear that it is easy to identify with the sorts of scans you've had.
So I'm inclined towards the view that its not likely to be
- your valve
- pannus
- throbosis obstructions from improper INR management.
2 and 3 are treatable with transvascular catheter procedures.
Speaking for myself when I've had a few weeks of not cycling I feel tightness in the chest on the deep breathing involved when I cycle (I do it to train, not to just tootle thru the park) but this clears up within 2 days. Could it just be that you're not training much?
Do you have a Heart Rate monitor type watch? What happens when you walk up stairs or such. A cheap and worth purchase is such a smart watch to just see. Everything on the spectrum from an eBay Cheapie to a Garmin or (forgive me) an Apple watch (washes my mouth out).
I would also consider a second opinion.
But overall ... don't worry, that'll just increase the symptoms. Lastly some 2000 year old advice from Marcus Aurelius:
