UT Southwestern patient first in North Texas to receive newest-generation heart failure device
Date:10/26/2009

hospitals, Mr. LeBlanc was referred to UT Southwestern University Hospital St. Paul, where he met with cardiologists and cardiothoracic surgeons who determined he would be a good candidate for the new LVAD.

"Mr. LeBlanc has cardiomyopathy, which causes the heart to dilate. The muscle becomes weaker, and it can't pump efficiently," said Dr. Dan Meyer, professor of cardiovascular and thoracic surgery at UT Southwestern and Mr. LeBlanc's surgeon. "UT Southwestern has always had a presence in studying new mechanical assist devices, so we were honored to be only one of two sites in the state selected to implant the HeartWare LVAD as part of a national clinical trial."

The pump is designed to rest inside the patient's chest. A small cable attached to the device exits the body and connects to an externally worn controller. The controller is powered by a battery pack. The HeartWare LVAD has only one moving part, which contributes to its diminutive size. The lack of mechanical bearings is expected to lead both to longer-term device reliability and to a reduced risk of physical damage to blood cells as they pass through the pump, said Dr. Meyer, also director of the mechanical support program at UT Southwestern.

"The size of the device means the incision is also smaller. The entire implantation surgery takes about four hours," Dr. Meyer said. "Mr. LeBlanc is a really great patient. He's otherwise very healthy, and we believe he will do very well with the LVAD until he can get a new heart."

Only a few days after his surgery to implant the device, Mr. LeBlanc said he was feeling much better and he hopes for a quick return to his daily routine. He's still adjusting to some of the stranger side effects of his new device, including no pulse. The LVAD keeps blood moving continually with no pulsation, so he no longer has a palpable heart beat or traditionally measurable blood pressure.

"I'm very happy to have this LVAD, and I think I'll
