His heart was failing for some reason(s). I don't see how transplant would ever make those go away, at best it would only buy him some time allowing those reasons to be removed. In some lucky cases, those do get removed automatically but I would expect in most of the cases, they would be left intact and will eventually cause heart to fail again soon. This does not even consider the immune system reactions, taking those into consideration, the chance would be very little.
