Has a fighter (boxer, kick boxer, wrestler) ever come back from open heart surgery?

I'm curious if anybody in professional combat sports has had open heart surgery and returned to their sport. If so, who, when, and what sport?

1. not to my knowledge good question though
2. not that i know of but boxing is ruff he would have to pass boxing commission physcal
3. Not to my knowledge. If there was someone, then he/she did a damn good job hiding something like that from media and commission, who would have to approve of such a feat. And I can't see commission allowing something like that, considering the physical demand of such sports.
4. yes some of them have because if they get hit in the chest they can die if the presure is to high in the chest.
