Revolutionary New Total Artificial Heart One Step
Closer to Reality, Thanks to $4.2 Million Grant from National Institutes of
Health
May 23, 2000 ,SALT LAKE CITY —A
revolutionary new total artificial heart being developed by researchers at
LDS Hospital, the Utah Artificial Heart Institute, and MedQuest Products
Inc., is one step closer to reality thanks to a new $4.2 million grant
awarded to the team by the National Institutes of Health.
The four-year grant is the first award given to artificial
heart researchers under the NIH’s new Bioengineering Research Partnership
program. The award was announced by the NIH’s National Heart, Lung, and
Blood Institute in Bethesda, MD.
“This grant reaffirms Utah’s world leadership in the
development and clinical use of artificial heart technology,” says James W.
Long, MD, director of the artificial heart program at LDS Hospital, and an
investigator on the grant.
The Utah-led team is the only recipient of significant NIH
funds to complete the development of a new, revolutionary
magnetically-suspended total artificial heart, known as the HeartQuest. The
HeartQuest total artificial heart offers heart failure patients the promise
of improved reliability and longevity over existing artificial hearts since
it contains no friction-based internal parts that are prone to wear out
over time. The HeartQuest will also be 30 to 40 percent of the size of
existing total artificial hearts.
“The HeartQuest total artificial heart has a rotor that is
suspended in a magnetic field so there are no internal touching parts,”
says Dr. Don Olsen, president of the Utah Artificial Heart Institute, and
the grant’s lead investigator. “Because of this unique design, we believe
it may add 10 to 20 years of quality life for hundreds of thousands of
people who would otherwise die of heart failure every year.”
In the United States, more than 250,000 people die each
year from severe heart failure, while millions more are hospitalized. While
heart transplantation is an option for some patients, only about 2,000
donor human hearts are available annually for transplantation.
“The HeartQuest pump will immeasurably benefit heart
failure patients in desperate need of a cost-effective, reliable, totally
implantable artificial heart that provides a high quality of life,” says
Pratap Khanwilkar, president of MedQuest. “This pump will enable recipients
to return to normal activities, such as going back to work, and enjoying
moderate exercise, such as hiking and golf.”
In making the award, the independent NIH review panel
comprised of 10 engineering experts, nine medical and surgical experts, and
one industry leader reported that ‘further advances in the field of heart
failure treatment await the technological innovations proposed by the
team’.
Using proprietary technology, an implantable-size
HeartQuest prototype has already been designed and assembled by the
development team. The design for clinical use is being completed , and will
be developed and fully tested in the next two years.
The HeartQuest artificial heart development will continue
to be supported through funding by the LDS Hospital-Deseret Foundation’s
Heart & Lung Research Foundation. This philanthropic-based support has
been complemented by the NIH grant. The development team expects to soon
obtain additional financial support to reach the goal of clinical delivery
of the HeartQuest total artificial heart in 2002.
LDS Hospital revived the use of the total artificial heart
in Utah in April of 1995, when a team led by Dr. Long successfully
implanted a CardioWest C-70 total artificial heart in Boise resident Al
Marsden as a bridge-to-transplantation. LDS Hospital was only the third
center in the nation to implant the C-70 and the first Utah medical center
to implant a total artificial heart since Dr. Barney Clark was implanted
with a permanent total artificial heart at the University of Utah in 1982.
LDS Hospital currently is the only Utah center implanting total artificial
hearts.
The HeartQuest development is being conducted by an
already-existing partnership between: Intermountain Health Care’s LDS
Hospital; the Utah Artificial Heart Institute; and MedQuest Products Inc.
They are being assisted by the University of Virginia, Charlottesville,
Virginia; Magnetic Moments LLC, Goleta, California, and Antakamatics Inc.,
Pittsburgh, Pennsylvania.
Company Background
MedQuest is a pioneer in the development of implantable
ventricular assist devices (VADs). The HeartQuest™ VAD is an implantable,
centrifugal pump that utilizes a magnetically suspended impeller to provide
a frictionless, wear-free pumping action. A VAD boosts the output of a
failing heart to normal levels. Congestive heart failure is the fastest
growing segment of the cardiovascular disease market and is diagnosed in
550,000 Americans each year; over 200,000 deaths annually are attributed to
congestive heart failure according to American Heart Association 2002
statistics .
