100 Days Without a Human Heart: Australian Man Makes Medical History
In a groundbreaking medical achievement, an Australian man with severe heart failure has become the first person in the world to survive over 100 days with a total artificial heart before receiving a donor transplant, researchers announced on Wednesday (March 12).
The BiVACOR “Total Artificial Heart”, invented by Australian scientist Dr. Daniel Timms, is the first fully implantable device designed to function as a complete replacement for the human heart. Unlike previous heart-assist devices, BiVACOR replicates both sides of the heart using a single moving part, no valves, and a no-contact suspension system—a design aimed at reducing mechanical wear and extending durability.
The six-hour procedure took place in November 2024 at St Vincent’s Hospital Sydney, where the 40-year-old patient relied entirely on the artificial heart for over 100 days while awaiting a donor. Doctors say he is the first Australian to undergo the procedure and one of only six people worldwide to receive the device.
Originally designed as a bridge to transplant, BiVACOR’s long-term goal is to become a permanent solution for heart failure patients who may never receive a donor organ.
