There is an artificial heart that can take the place of a real heart for a short term. But so far they have not developed one that is able to last as a long-term replacement.
Incidentally, I'm curious to know what you mean by "incredibly annoying". If you're speaking of emotions they really have nothing to do with your heart at all, even though they are often spoken of as coming "from the heart". In fact they are all in the brain.
