The Texas Heart Institute is a world leader in the development, testing and application of heart assist devices. Our goal for the surgical research conducted here is to develop and determine the best assist device to use for each individual patient. Devices may be referred to as mechanical assist devices, ventricular assist devices (VAD), left ventricular assist devices (LVAD), total artificial hearts (TAH), or simply heart pumps.
The adjacent list describes devices currently in use at THI as well as those of historical interest and those in the research and development stages.

Keeping hearts pumping
Doctors push the limits of heart-pump technology in an effort to save lives. Dr. Bud Frazier often tells a story about when he was a medical student in the 1960s ... Frazier had this thought: If I can keep a man alive with my hand, why can't we make a pump that we can pull off of the shelf to do the same thing? Dr. Billy Cohn, another physician who works at the cutting edge of heart pump technology, likes to use the history of human flight as an analogy for the evolution in his field. Experimenters in both domains had to give up the idea of bio-mimicry to advance the technology. "It is similar to when man first tried to build a flying machine with flapping wings that mimic the birds. It is obvious now that fixed wings were the way to go," he says. "We think it is the same with the nonpulsatile pump, which, because it has only one moving part, is much more durable." - Houston Chronicle [Photo credit Mayra Beltran]

FDA Approves HeartWare LVAD for HF
The FDA gave the green light for the HeartWare Ventricular Assist System
as a bridge to heart transplantation in patients with heart failure.
"The miniaturized device with an integrated inflow cannula is placed
within the pericardial sac . . . simplifying the surgical insertion,"
said O.H. "Bud" Frazier, MD, of Texas Heart Institute. Read the full story from medpagetoday.com.

Craig Lewis lay dying in a Texas hospital bed. The 55-year-old was suffering from amyloidosis, a disorder that was destroying his heart. "This man was basically within an hour or two of death," says Billy Cohn, a doctor at Houston's Texas Heart Institute who oversaw Lewis earlier this year. Given Lewis's dire condition, Cohn and veteran artificial heart researcher Bud Frazier received the consent of the man's family to try something that had never been done before: the complete replacement of his heart with two continuous flow ventricular assist devices (VAD).
