For the first time in history, a patient has been discharged from the hospital with a total artificial heart implant, marking a major milestone in cardiovascular medicine. An Australian man in his 40s, experiencing severe heart failure, lived for over 100 days with the BiVACOR total artificial heart before receiving a donor transplant in early March. The groundbreaking achievement, led by surgeons at St Vincent’s Hospital in Sydney, has been hailed as an “unmitigated clinical success.”
The BiVACOR total artificial heart, developed by Queensland-born Dr. Daniel Timms, is the first implantable rotary blood pump designed to completely replace human heart function. Utilizing advanced magnetic levitation technology, the device mimics the natural flow of a healthy heart, providing a potential lifeline for patients with end-stage biventricular heart failure.
Addressing the global heart failure crisis
Heart failure affects more than 23 million people worldwide, yet only 6,000 receive life-saving donor heart transplants each year. The BiVACOR device aims to bridge this gap by keeping patients alive until a transplant becomes available. Looking ahead, the developers hope it will eventually serve as a long-term solution, eliminating the need for donor transplants altogether.
End-stage biventricular heart failure occurs when both sides of the heart lose their ability to pump blood effectively. It is often the result of conditions such as heart attacks, coronary artery disease, or complications from diabetes. Without intervention, survival rates are low, making innovative solutions like the BiVACOR heart essential.
The Australian government has invested 50 million dollars in the artificial heart frontiers program to develop and commercialize the BiVACOR device, underscoring its significance as a potential game-changer in cardiac treatment.
A historic procedure
On November 22, a team of surgeons at St Vincent’s Hospital, led by cardiothoracic and transplant surgeon Paul Jansz, performed the six-hour procedure to implant the artificial heart. The patient, who wishes to remain anonymous, became the sixth person in the world to receive the device and the first to leave the hospital while still using it.
Previously, five patients in the United States had received the BiVACOR implant, but all underwent donor transplants before hospital discharge. The longest time any of those patients had relied on the artificial heart before transplant was 27 days—far less than the 100-plus days of the Australian patient.
Jansz called the moment “a privilege” and expressed pride in leading Australia’s first total artificial heart implantation. “We’ve worked towards this moment for years and we’re enormously proud to have been the first team in Australia to carry out this procedure,” he said.
A game-changer for heart transplantation
The success of the procedure signals a significant shift in how heart failure is managed. Professor Chris Hayward, a cardiologist at St Vincent’s who monitored the patient post-surgery, believes the BiVACOR heart has the potential to transform heart transplantation worldwide.
“The BiVACOR total artificial heart ushers in a whole new ball game for heart transplants, both in Australia and internationally,” Hayward said. “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.”
Despite the success, experts acknowledge that the technology still has limitations. Professor David Colquhoun from the University of Queensland and the Heart Foundation noted that while this is a “great technological step forward,” the artificial heart’s lifespan—just over 100 days in this case—is significantly shorter than that of a donor heart, which can last more than 10 years.
There is still “a long way to go” before the artificial heart can be considered a true replacement for heart transplants, Colquhoun said. However, he also highlighted the broader progress in heart disease treatment, citing that the mortality rate from heart disease has significantly declined since the late 1960s, thanks to advancements in medication and technology.
The future of artificial hearts
This historic case is just the beginning. The artificial heart frontiers program, led by Monash University, is developing multiple devices to address the most common forms of heart failure. As research continues, the potential for artificial hearts to extend and improve the lives of patients worldwide becomes increasingly promising.
With the successful implementation of the BiVACOR heart, Australia has taken a pioneering step toward redefining heart failure treatment. While challenges remain, this breakthrough offers hope that, in the near future, more patients will have access to life-saving alternatives beyond traditional heart transplants.
