So here is a picture of what I am facing
Is this a sign of heart rot? What should I do?
It seems to be confined to this one branch (no apples on that branch at all).

Remove that whole limb ASAP. It's at least "mostly dead" if it's got shelf fungus growing on it.
The fungus is a symptom, not the cause, but you want to remove the dead wood regardless.
