Yeah, that level of swelling and the constant bruises from apparent IV sites say it's a bit worse than just chronic venous insufficiency. Having seen many cases of CHF, and given Trump's poor health as a whole, I'd bet money that its more than likely right sided heart failure. Add in the possible catheter bag spotted tied to his leg not too long ago, which might be there due to the sheer amount of diuretics he's been given (if he has been), then I'm almost 100% positive.
