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

eIuThis first-ever, pure PAVR procedure, requiring no surgical cut-down, on a eIhigh riskeIU patienteI|89 years old and too frail for open-heart surgeryeI|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.eIN

IRVINE, Calif. -- CoreValve (www.corevalve.com) 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 eIpureeIU 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.

eIuThousands 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,eIN said Prof. Serruys. eIuI believe that ReValving can give these patients a truly percutaneous option performed by the interventional cardiologist in the cath lab.eIN Added Dr. DeJaegere: eIuThe 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.eIN

eIuTo 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),eIN said Jacques S[R] guin, M.D., Ph.D., Chairman, CEO and Founder of CoreValve. eIuOur 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.eIN

About CoreValve

Founded in 2001, privately held CoreValveeI|which is headquartered in Irvine, CaliforniaeI|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 procedureeI|with the proprietary CoreValve Percutaneous ReValvinge SystemeI|can be performed in a cardiac eIucath labeIN just like angioplasty and stenting, resulting in less trauma to the patient and substantial cost-savings to the healthcare system.
