CoreValve Announces That More Than 1,800 High-Risk Patients Have Been Treated with its ReValving® System for Percutaneous Aortic Valve Replacement (PAVR) : Highly encouraging registry data also presented at TCT 2008

CoreValve (http://www.corevalve.com) announced today that the expanded clinical evaluation of its ReValving® System for percutaneous aortic valve replacement (PAVR) in high-risk patients with aortic stenosis continues to enroll patients at an accelerating pace. More than 1,800 patients have now been treated worldwide at nearly 100 centers in 20 countries.

In the hands of an experienced user, use of the CoreValve ReValving System is fast becoming a routine alternative for high risk patients suffering from severe aortic stenosis.

IRVINE, Calif. (PRWEB) October 13, 2008

During the Monday Transcatheter Aortic Valve Replacement sessions at TCT 2008 meeting in Washington, D.C., CoreValve investigators and physician proctors presented clinical data on the subset of patients that are included in the company's post CE-Mark expanded clinical evaluation registry. Patients enrolled in the registry had a predicted 30-day mortality rate of about 23% as measured by the logistical EuroScore. By contrast, the survival rate at one-month post-procedure follow-up for these high-risk and often inoperable octogenarian registry patients was about 90%. Quality of life improvement, as measured by the New York Heart Association (NYHA) functional classification, was significantly improved as well. Follow-up on patients that are now one year post procedure demonstrate good longer term valve function and sustained survival and quality of life benefits. CoreValve believes that complications including neurological events are comparable to traditional aortic valve surgery although there is a modest, but clinically acceptable increase in pacemaker dependency in PAVR patients.

"The growing volume of very positive clinical data from an ever increasing number of physicians is most satisfying," said Eberhard Grube MD, Chief of Cardiology at the HELIOS Heart Center Siegburg, Germany. "In the hands of an experienced user, use of the CoreValve ReValving System is fast becoming a routine alternative for high risk patients suffering from severe aortic stenosis."

"We are highly encouraged by the clinical data from outside the United States that was presented at TCT," added Daniel T. Lemaitre, President and CEO of CoreValve. "Additionally, we continue to see strong sequential growth in procedure volume as 2008 unfolds; a testimony to the significant patient population whom we believe will benefit from our groundbreaking technology."
