An Australian man lived for 100 days with an artificial titanium heart whereas he awaited a donor transplant, the longest interval up to now of somebody with the expertise.
The affected person, a person in his 40s who declined to be recognized, acquired the implant throughout surgical procedure at St. Vincent’s Hospital Sydney final November.
In February, he grew to become the primary individual worldwide to go away hospital with the machine, which stored him alive till a heart donor grew to become obtainable earlier this month.
According to an announcement issued Wednesday by St Vincent’s Hospital, Monash University and BiVACOR, the US-Australian firm behind the machine, the person, who had extreme heart failure, was “recovering well.”
The skill of the machine to maintain him for so lengthy is being celebrated as an indication the artificial heart might doubtlessly provide a long-term choice for individuals struggling heart failure. The machine continues to be being trialed and has not but been accredited for common use.
BiVACOR’s founder, Australian bioengineer Daniel Timms, who invented the machine following his father’s demise from heart illness, stated it was “exhilarating to see decades of work come to fruition.”
“The entire BiVACOR team is deeply grateful to the patient and his family for placing their trust in our Total Artificial Heart,” he stated in the assertion. “Their bravery will pave the way for countless more patients to receive this lifesaving technology.”
The BiVACOR Total Artificial Heart (TAH) has a single shifting half, a levitated rotor that’s held in place by magnets. As the identify suggests, it’s constructed from titanium and there are not any valves or mechanical bearings that could be inclined to put on.
It pumps blood to the physique and the lungs, changing each ventricles of a failing heart.
Cardiovascular ailments are the main reason behind demise globally killing round 18 million individuals every year, according to the World Health Organization.

Reducing the chance of heart illness
The long-term ambition is to make use of the machine to avoid wasting extra individuals who languish on ready lists for appropriate donors. According to the US Health Department, about 3,500 individuals acquired heart transplants in 2024. Around 4,400 joined the ready listing the identical yr.
Professor Chris Hayward, from the Victor Chang Cardiac Research Institute, stated the BiVACOR heart ushered in “a whole new ball game for heart transplants.”
“Within the next decade we will see the artificial heart becoming the alternative for patients who are unable to wait for a donor heart or when a donor heart is simply not available,” stated Hayward, who’s overseeing the Australian affected person’s restoration and was concerned in making ready the machine for scientific trials.
The machine has already been examined in the Food and Drug Administration’s Early Feasibility Study in the United States, which noticed 5 sufferers efficiently implanted with the machine.
The first was final July, when a 58-year-old man struggling end-stage heart failure acquired the implant throughout surgical procedure at Texas Medical Center. It stored him alive for eight days till a donor was obtainable.
Four different sufferers adopted in the examine, which examined the protection and efficiency of the machine, whereas they waited for a donor transplant. It’s hoped the trial will broaden to fifteen sufferers.
The Australian implant was the primary in a collection deliberate by Monash University’s Artificial Heart Frontiers Program, a 50 million Australian greenback ($31 million) program to develop and commercialize three units to deal with heart failure.
