I've had a RBBB for years, and is no real concern to the CAA or FAA.
I too in December last year had PVR operation and now have my JAA class One medical back. Got it back 5 months post op.
Dont worry in the slighest about a RBBB, as long as you in sinus rhythm, thats the main thing.
PM me if you need any advice, can give you my recent exdperince with it all.
