It seems to me that the purpose of a push over the top is not isolation (unless you seriously think someone is going to fold a weak A2xx here); it's to allow you to see both remaining streets for a fixed price. If you flat call and get two callers (pot is now $205), and the turn brings a non-heart A,3,6,7, or 8, then calling a turn bet will be difficult (though only BreakUrHeart will really have enough left behind to make it significantly -EV).
