just going to give a bit of my perspective on your topic if I may
increased bilirubin in and of itself can be due to the following liver and NON liver issues :
pre-hepatic, hepatic or post hepatic issues
SO ... the docs need to be looking and any and ALL potential causes
... also, there will be differing lab reference values for bilirubin ( conjugated and non-conjugated )
SO you would need to quote the lab normals for his own reference lab, in order for that value to be relevant
in context of discussions here... 1-2 points elevated, 10-20 points up, doubled tripled etc. ?
when you say "jaundiced" ... is he actually appearing to have a yellowish cast to his skin / whites of the eyes etc ????
IF the current Docs are not giving you answers you need ... possibly consider a second consult with an Internal Medicine specialist ????
With existing cardiac issues ... Yes, I am afraid there can be ascites issues .. AND in my own medical experience .. possibly a cardiac connection to the liver ( which would be rare but not impossible )
ALSO .. as was mentioned .. what meds is he on ??? some will have hepatic "issues"
You need to get all the docs on board and KEEP PUSHING for answers
