March 11, 2011 – Texas Children's has become the world's first pediatric hospital to complete the first phase of certification to implant the SynCardia temporary Total Artificial Heart. The hospital intends to use the device as a bridge to transplant for their patients who received a heart transplant as children and now require mechanical support as a bridge to their second transplant.
The 15-member training team, which included cardiologists, critical care intensivists, anesthesiologists, nursing specialists and hemotologists, was led by David L.S. Morales, M.D., pediatric cardiovascular surgeon and director of mechanical circulation support at Texas Children's Hospital. This first-phase of certification prepares the team for future implantation of the device into patients who meet specific body-size qualifications.
Similar to a heart transplant, the Total Artificial Heart replaces both failing ventricles and the four cardiac valves. Once implanted, it pumps up to 9.5 liters per minute through both ventricles to provide increased blood flow to vital organs such as the brain, kidneys and liver. Unlike a donor heart, the device is instantly available before the patient's organs begin to fail and doesn't require expensive, anti-rejection medication, which can cause subsequent complications.
"Over the past few years as a transplant surgeon at Texas Children's Hospital, I have witnessed several patients who needed a second transplantation, but died before a donor heart became available," said Morales. "Those patients would have been excellent candidates for an immediately-available heart. The Total Artificial Heart is the only device that allows us to remove the failing donor heart completely and bridge patients to a second transplant without immunosuppressive therapy."
Of the more than 20 patients currently listed for a heart transplant at Texas Children's, more than 20 percent are waiting for their second donor heart. Since its inception in 1984, Texas Children's heart transplantation program has grown into one of the largest and most successful of its kind in the nation, having transplanted 248 pediatric patients.
