Well, today hearts are replaced by perfectly healthy hearts of other people and yet life expectancy after such a procedure is not great and patients have to take meds for as long as they live. Also cardiovascular performance is much reduced. So as long as this is not working really well, i guess growing hearts and replacing them is still a long way off. Also there are other kinds of common cardiovascular disease like coronary heart disease which can't be fixed by replacing the heart.
