CoreValve announces successful completion of world's first 'pure' percutaneous aortic valve replacement (PAVR) procedure utilizing its patented ReValving(TM) system

"This first-ever, pure PAVR procedure, requiring no surgical cut-down, on a 'high risk' patient--89 years old and too frail for open-heart surgery--offers additional unmistakable confirmation that our ReValving approach to percutaneous aortic valve replacement is progressing quickly toward becoming the future alternative to open-heart surgery."
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 bioprosthesis over the severely calcified aortic heart valve of an 89-year-old female patient. In contrast to long post-surgical recuperation times, this 'pure' PAVR patient was discharged from the ICU to the general ward on the morning after her ReValving procedure and was fully mobile and awaiting discharge from the hospital.

The successful procedure was performed at Erasmus University Medical Center, Rotterdam, The Netherlands, by Professor Patrick W. Serruys and Dr. Peter DeJaegere, globally recognized interventional cardiologists who have been leading investigators in clinical trials of numerous cutting-edge technologies.

"Thousands of critically ill patients with severe aortic valve stenosis are refused surgery every year, and the annual mortality rate is as high as 25 percent in this frail population," said Prof. Serruys. "I believe that ReValving can give these patients a truly percutaneous option performed by the interventional cardiologist in the cath lab." Added Dr. DeJaegere: "The fact that the ReValving delivery catheter has been reduced in size to 18-French not only makes maneuverability and general handling of the ReValving system superior to previous-generation devices. It has made a true percutaneous femoral access possible and also a true and complete percutaneous procedure when using p-LVAD support during the implantation."

"To date, the ReValving patients who have been discharged from the hospital continue to demonstrate improved cardiac function, absence of long-term complications, and dramatically enhanced quality-of-life at follow-up out to more than 14 months (mean: 6.9 months)," said Jacques Seguin, M.D., Ph.D., Chairman, CEO and Founder of CoreValve. "Our swift technological advancements are the outcome of a strategy that concentrated on a breakthrough design for a bioprosthesis dedicated to a purely percutaneous application. With this latest clinical achievement, we have demonstrated that aortic valve replacement is no longer restricted to surgical or transcatheter options, and we have further entrenched CoreValve as the indisputable front-runner in this new interventional frontier. We continue to believe we are on schedule to secure a CE Mark and first-to-market position for our ReValving System in Europe next year."

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.
