SynCardia Total Artificial Heart Patient with
End-Stage Renal Failure Recovers Kidney Function after Two Months of Support
20-Year-Old Tiernee Gonzalez Begins Producing Urine Day Before Scheduled Surgery to Implant Permanent Catheter
TUCSON, Ariz. – Feb. 21, 2013 – At only 20 years old, Tiernee Gonzalez has been battling two major diseases for most of her young life: heart failure and kidney failure. When she became the first patient at Cincinnati Children’s Hospital Medical Center to receive the SynCardia temporary Total Artificial Heart on Nov. 9, her doctors hoped it would bring her one step closer to winning her battle against end-stage heart failure. What they didn’t expect, was that it would also help save her one remaining kidney.
“The SynCardia Total Artificial Heart is the only device that lowers CVP to single digits, which creates the potential for liver and kidney recovery,” said Dr. David L.S. Morales, chief of pediatric cardiothoracic surgery at Cincinnati Children’s. “In the case of this patient, what we initially defined as end-stage renal failure simply became delayed recovery thanks to the total artificial heart.”
As a young girl, Gonzalez suffered from a form of kidney cancer called renal cell carcinoma. In addition to having one of her kidneys removed, she had to undergo chemotherapy, which weakened her heart. In August 2006, the summer before she started eighth grade, Gonzalez received a heart transplant.
However, over the next few years, her body rejected the donor heart and her health began to deteriorate. She progressed to end-stage renal failure and was looking at needing dialysis for the rest of her life. Doctors didn’t think she would survive the wait for another heart transplant, so they decided to implant the SynCardia Total Artificial Heart.
“I was nervous at first, obviously,” said Gonzalez. “After I got over the initial shock, I just kind of thought, ‘OK… They’re going to put this device in me and I’m not going to have a heart. It’s going to be mechanical.’”
For almost two months after the implant surgery, Gonzalez continued to produce no urine, so she was scheduled for surgery on Jan. 2 to receive a permanent catheter. However, on Jan. 1, she began making urine.
“Even I had started to lose hope,” said Dr. Morales. “And now, she has normal function to her kidney. This experience has made me very optimistic that many of the livers and kidneys that fail due to heart disease could actually be recoverable with the total artificial heart. Every time we put in this device, we learn something new.”
On Jan. 12, Cincinnati Children’s received approval from the FDA to switch Gonzalez to the Freedom® portable driver, the world’s first wearable power supply for the SynCardia Total Artificial Heart. The Freedom driver will allow Gonzalez, who feels healthier than she has in years, to leave the hospital and return home for the first time since October.
“I keep telling her that I don’t know what God’s plan is, but there is a plan,” said Gonzalez’s mother, Leslie Hudson. “And she just has to keep pushing through.”
The Freedom driver is CE approved for use in Europe and undergoing an FDA-approved Investigational Device Exemption (IDE) clinical study in the U.S.

CAUTION – The Freedom portable driver is an investigational device, limited by United States law to investigational use.
SynCardia Systems, Inc. in Tucson, Arizona is the privately-held owner and manufacturer of the world's first and only FDA, Health Canada and CE approved Total Artificial Heart.
Originally used as a permanent replacement heart, the SynCardia Total Artificial Heart is currently approved as a bridge to transplant for people suffering from end-stage biventricular heart failure in which both ventricles can no longer pump enough blood for a person to survive.
More than 1,350 implants of the SynCardia Total Artificial Heart accounts for over 400 patient years of life on the device. Since January 2011 more than 400 SynCardia Hearts have been implanted.
SynCardia Systems also manufactures the Freedom® portable driver, which powers the SynCardia Heart while allowing clinically stable patients to leave the hospital to live at home and in their communities. The wearable Freedom driver has been used by over 190 patients, accounting for over 110 years of support.
