An Australian man in his forties has become the first person in the world to leave hospital with an artificial heart made of titanium. The device is used as a stopgap for people with heart failure who are waiting for a donor heart, and previous recipients of this type of artificial heart had remained in US hospitals while it was in place.

For decades, replacing a failing human heart meant waiting—often desperately—for a donor. But in a hospital in Sydney, that paradigm has begun to shift. Last November, surgeons at St Vincent’s Hospital in Sydney implanted the BiVACOR Total Artificial Heart in a critically ill patient.
