Led by cardiothoracic surgeons Mark Slaughter, M.D., and Siddharth Pahwa, M.D., each of UofL Health – UofL Physicians and the UofL School of Medicine, the workforce carried out the implant of the machine on Sept. 14, 2021 at UofL Health – Jewish Hospital. The identical workforce accomplished the nation’s second implantation in a male affected person final month, additionally at Jewish Hospital.
“For the other half of the world’s population, completion of this procedure by the Jewish Hospital team brings new hope for extended life,” mentioned Slaughter, UofL Health surgical director of coronary heart transplant and professor and chair of the Department of Cardiovascular and Thoracic Surgery within the UofL School of Medicine.
“Size limitations can make it harder to implant artificial hearts in women, but the Aeson artificial heart is compact enough to fit inside the smaller chest cavities more frequently found in women, which gives hope to a wider variety of men and women waiting for a heart transplant and increases the chances for success.”
More than 3,500 people are awaiting a coronary heart transplant within the U.S. and 900 of them are ladies. There are few remedy choices for sufferers with biventricular coronary heart illness, that means each the left and proper sides of the guts usually are not pumping blood adequately.
The Aeson machine is designed to resolve the constraints of present left-ventricular help units (LVAD), which pump blood in only one chamber, by pumping blood in each coronary heart chambers.
Aeson additionally comprises stress sensors that estimate the affected person’s blood stress and routinely adapts cardiac output based on the sensor data. It is totally implanted as a coronary heart substitute and powered by a transportable exterior energy provide.
During this process, the Aeson total synthetic coronary heart was implanted right into a 57-year-old Kentucky girl with extreme biventricular coronary heart failure throughout an eight-hour surgical procedure.
The recipient, whose id is being withheld upon request, was referred to the Advanced Heart Failure Therapies Program at Jewish Hospital earlier this yr with end-stage coronary heart failure and had undergone cardiac surgical procedure years earlier than.
The affected person is recovering nicely within the cardiovascular intensive care unit (CVICU). Jewish Hospital is only one of 4 applications within the nation authorized to carry out this medical trial process.
“The varying pumping ability of the Aeson device increases its viability among more patients,” mentioned Pahwa, UofL Physicians cardiothoracic surgeon and assistant professor within the UofL Department of Cardiovascular and Thoracic Surgery.
“While other devices are set at a fixed rate or create a continuous flow, CARMAT has developed the Aeson to automatically adjust the flow, creating an improved performance to meet the body’s changing blood flow needs.”
Currently, the Aeson synthetic coronary heart is examined as a bridge to transplant for sufferers with end-stage biventricular coronary heart failure, permitting extra time for the affected person to obtain a everlasting coronary heart organ transplant.
The machine already has been authorized for such use in Europe, the place roughly 20 units have been implanted. It at present is being examined within the U.S. as a part of a feasibility examine authorized by the Food and Drug Administration.
The first Aeson synthetic coronary heart in North America was implanted in a male affected person in July at Duke University Medical Center. The second implantation, additionally in a male affected person, was carried out at Jewish Hospital in August. This third North American implantation is the primary to contain a feminine affected person.
“Even as we have fought this deadly pandemic, our researchers and health care providers have also been on the front lines of improving care and quality of life for not only Kentuckians, but for people around the world,” mentioned Kentucky Gov. Andy Beshear.
“I am proud that UofL, Jewish Hospital and their doctors are leading the world in implanting this promising and innovative device that could offer hope and time to thousands of people, including our wives, mothers and other loved ones, in coming years.”
Stéphane Piat, chief govt officer of CARMAT, mentioned, “This third implant in the U.S. was a landmark event not only because it allowed us to finalize the enrollment of the first cohort of patients of the EFS, but very importantly because it is the first time ever that our device has helped a woman suffering from heart failure. This achievement confirms that the size limitations for adults are minimal, which makes us very confident in Aeson’s potential to become a therapy of choice for a broad patient population.”
Preclinical analysis for CARMAT’s synthetic coronary heart started at UofL greater than 5 years in the past. Researchers at UofL’s Cardiovascular Innovation Institute (CII) examined Aeson’s autoregulation functionality, which permits the machine to adapt its flows based on the affected person’s wants by detecting adjustments of stress within the machine.
UofL researchers have performed preclinical testing of synthetic coronary heart parts and mechanical help units at CII for a few years, testing some portion of practically each mechanical help machine that’s commercially out there right this moment.
Jewish Hospital and the University of Louisville share a storied historical past in advancing coronary heart care. Highlights embrace:
- Aug. 24, 1984: Kentucky’s first coronary heart transplant carried out at Jewish Hospital by UofL physicians
- July 2, 2001: The world’s first AbioCor® synthetic coronary heart was implanted at Jewish Hospital by UofL physicians, led by cardiothoracic surgeon Laman Gray, M.D.
- Dec. 21, 2011: Kentucky’s first transcatheter aortic-valve substitute (TAVR) carried out at Jewish Hospital by UofL physicians
- Jan. 18, 2015: Kentucky’s first HeartMate 3TM left ventricular help machine (LVAD) implanted at Jewish Hospital by UofL physicians
- Feb. 21, 2018: UofL Health – Trager Transplant Center’s five hundredth coronary heart transplant carried out at Jewish Hospital

- April 22, 2021: UofL Health – Trager Transplant Center’s one thousandth TAVR carried out at Jewish Hospital
“This world-first artificial heart implant into a female patient is another demonstration of UofL Health’s commitment to provide both the world-class care of today and develop the world-class standards of tomorrow,” mentioned John Walsh, chief administrative officer of Jewish Hospital.
“We celebrate this first as a milestone and recognize the hard work of Drs. Slaughter and Pahwa and the entire team. The true impact of their work will be measured in the dozens, hundreds and thousands of lives improved in the years to come.”
The affected person who acquired the nation’s second Aeson implant, on Aug. 20, 2021, continues to enhance at Jewish Hospital. An replace is anticipated within the coming weeks.
