CoreValve's ReValving(TM) System Demonstrated 'Live' at Opening Session of TCT 2005 to an Audience of 12,000 Interventional Cardiologists and Device Industry Executives.

IRVINE, Calif., and PARIS -- E[acute accent]ReValving(TM) was used instead of open-heart surgery to non-surgically implant a new aortic bioprosthesis over the diseased heart valve

E[acute accent]"The fact that we were willing to show a 'live' ReValving procedure to thousands of interventional cardiologists and business development executives at TCT 2005 sends a very strong message that we passionately believe ReValving is the next frontier in interventional cardiology." E[acute accent]Jacques Seguin, M.D., Ph.D. E[acute accent]Chairman, CEO and Founder, CoreValve

E[acute accent]CoreValve (www.corevalve.com) announced today that its second-generation, proprietary aortic heart valve was implanted successfully -- non-surgically -- in a 'high-risk' patient using CoreValve's percutaneous ReValving(TM) System, during the opening session at the Cardiovascular Research Foundation's (CRF) Seventeenth Annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, in Washington, D.C. Eberhard Grube, M.D., chief of cardiology at The Heart Center, Siegburg, Germany, and a consulting professor of medicine at Stanford University, and Jean-Claude Laborde, M.D., an interventional cardiologist at Clinique Pasteur in Toulouse, France, performed the ReValving procedure in the "cath lab" at The Heart Center. As a result, their patient was able to avoid open-heart surgery to treat a defective aortic heart valve. E[acute accent]CoreValve's ReValving(TM) procedure was performed today, 'live', via satellite television, for some 12,000 attendees at TCT 2005. This event represents the first-ever successful retrograde "live" percutaneous replacement of an aortic heart valve to an audience comprised of interventional cardiologists and industry business development executives in attendance at TCT. The Cardiovascular Research Foundation is the sponsor of the Annual Transcatheter Cardiovascular Therapeutics scientific symposium, one of the largest interventional vascular medicine meetings in the world. E[acute accent]"It is now dramatically obvious to literally thousands of interventional cardiologists around the world that CoreValve's ReValving System has enormous potential to non-surgically treat aortic valve disease," said Jacques Seguin, M.D., Ph.D., Founder, Chairman and CEO of CoreValve. "Today's successful 'live' ReValving procedure, which is part of our feasibility clinical trials and which, combined with the excellent results of our previous 20 cases, bears strong witness that ReValving will have a place in the future of interventional cardiology." E[acute accent]Of special note: The 'live' ReValving(TM) procedure at TCT used CoreValve's own proprietary porcine pericardium aortic heart valve, delivered via CoreValve's small 21-French-sized catheter, and required less than 15 minutes to be implanted.

E[acute accent]About CoreValve

E[acute accent]Founded in 2001, privately held CoreValve--which is headquartered in Paris and has R&D and manufacturing facilities in Irvine, California--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 Percutaneous ReValving System(TM)--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.
