Lots and lots and lots. All the issues with scarcity of donor hearts and tissue compatibility would just go away, and the main constraint on heart transplants would become the availability of a cardiac surgeon. Far fewer people would die while they were on a waiting list, and there would be much less incentive to drop anyone healthy enough to survive the surgery off the list entirely.
I wonder if there’ll ever be artificial heart that would last for decades, I imagine that would save lots of people.
