First Percutaneous Aortic Valve Replacement (PAVR) Procedure without Any Cardiac Support (i.e., Mechanical Assistance or Accelerated Pacing) Performed with CoreValve's Non-Surgical ReValving(TM) System

"This milestone is as important for the CoreValve ReValving technology as the first-ever procedure was--not only because it avoided open-heart surgery for these very frail patients, but also because these uneventful procedures were performed in a cath lab without the use of extracorporeal bypass, or cardiac assistance, or even rapid pacing. ReValving is rapidly becoming very similar to a routine cath lab intervention." Jacques Seguin, M.D., Ph.D., Chairman, CEO and Founder of CoreValve

IRVINE, Calif.--(HSMN NewsFeed)--CoreValve ( announced today that its patented ReValving System, consisting of a breakthrough 18-French-sized delivery catheter, was used to percutaneously implant its proprietary porcine pericardial tissue bioprostheses over the severely calcified aortic heart valves of an 88-year-old female patient and a 77-year-old male patient--without the use of extracorporeal bypass, other cardiac assistance or even rapid pacing. These first-ever medical-milestone procedures took routine interventional times to complete, and the patients were released from the ICU within hours of the completion of the ReValving procedure and are awaiting discharge from the hospital.

The successful procedures were performed at the HELIOS Heart Center (HHC), Siegburg, Germany, by Eberhard Grube, M.D., Chief of Cardiology and Angiology at HHC and a consulting professor of medicine at Stanford University.

"Since we performed the very first cases two years ago, ReValving continues to evolve toward a simple and straightforward cath lab procedure," said Dr. Grube. "The clinical investigators are gradually eliminating those procedural elements that are less conducive to the cath lab setting, and I commend the Company and its Scientific Advisory Board for designing study protocols that allow for procedural progress without compromising patient safety. As the clinical experience in Europe and North America now approaches 100 cases, there is no question in my mind that many patients in the future will be able to have their diseased aortic heart valve replaced percutaneously in a cath lab rather than having to endure open-heart surgery."

"This latest clinical accomplishment substantiates our conviction that aortic valve replacement is no longer limited to surgical or mere transcatheter alternatives and fortifies CoreValve's position as the undeniable leader in truly percutaneous valve replacement. We continue to work hard toward earning a CE Mark and first-to-market position for our ReValving System in Europe," said Jacques Seguin, M.D., Ph.D., Chairman, CEO and Founder of CoreValve.

About CoreValve

Founded in 2001, privately held CoreValve--which is headquartered 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(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.
