CoreValve reports new milestone: ReValving(TM) procedures are performed (a) without extracorporeal bypass, (b) without respiratory assistance, and (c) without intubation and full anesthesia

"With our imminent transition to an 18-French system and the anticipated continued use of temporary percutaneous left ventricular assist devices for unloading the heart, our entire ReValving procedure can now be a truly percutaneous alternative to open-heart surgery for replacing a diseased aortic heart valve."
- Jacques Seguin, MD, PhD, Chairman, CEO and Founder, CoreValve  

IRVINE, Calif.--(HSMN NewsFeed)--July 12, 2006--CoreValve ( announced today that cardiologists in Europe and Canada continue the validation of the CoreValve ReValving(TM) System as a truly non-surgical approach to aortic valve replacement. The latest progress was made possible by using CardiacAssist's TandemHeart® PTVA® System, a percutaneous left ventricular assist device (LVAD) that helps to unload the beating heart and assures continuous, naturally oxygenated blood circulation through a simple trans-septal catheterization procedure. The CardiacAssist device has received regulatory clearances in Europe and the U.S.

The first ReValving procedures using the CardiacAssist device were performed by Professor Patrick W. Serruys and Dr. Peter DeJaegere at Erasmus University Medical Center, Rotterdam, the Netherlands, and by Dr. Raoul Bonan at the Montreal Heart Institute, Quebec, Canada.

"The significance of these latest ReValving procedures is that they are the first to eliminate the need for a cut-down for fem/fem extracorporeal bypass, while retaining the cardiac support safety factor for the patient. By taking advantage of the CardiacAssist TandemHeart PTVA System technology, a purely percutaneous ReValving procedure is now possible," said Jacques Seguin, M.D., Ph.D., Chairman, CEO and Founder of CoreValve. "This development catapults CoreValve further into the technology lead in the percutaneous aortic valve replacement (PAVR) sector."

Added Rob Michiels, President and COO of CoreValve: "In essence, the TandemHeart PTVA System functions with the patient's own right heart and lungs to provide the equivalent of full cardiac bypass, and we are pleased to have this minimally invasive circulatory support system available so that our breakthrough ReValving procedure can be done safely and efficiently in the cath lab."

About CoreValve

Privately held CoreValve, with U.S. headquarters in Irvine, Calif., has developed a proprietary delivery system for percutaneous heart valve replacement, based on a novel catheter-and-self-expanding-frame approach on a beating heart, thus avoiding open-heart surgery. The CoreValve procedure--with the proprietary CoreValve ReValving(TM) System--can be performed in a cardiac 'cath lab' just like angioplasty and stenting, resulting in less trauma to the patient and substantial cost-savings to the healthcare system.
