Edwards Lifesciences Delays Percutaneous Aortic Heart Valve Clinical Trials to Incorporate New Delivery System

IRVINE, Calif., June 13, 2005 -- Edwards Lifesciences Corporation (NYSE: EW), the world leader in heart valve technologies, announced today that it is delaying enrollment in its percutaneous aortic heart valve clinical feasibility trials in the U.S. in order to incorporate a new delivery system being evaluated in Canada.

The company took this voluntary action after some U.S. antegrade cases demonstrated a greater degree of clinical complexity and adverse outcomes when compared to results of a Canadian study, where cases are being performed with a new retrograde delivery system. Data presented at the 2005 Paris Course on Revascularization in May indicated that the company's custom retrograde delivery system resulted in positive clinical outcomes.

"We recently have completed a number of procedural refinements, including the development of a simpler and more direct retrograde delivery approach, which has led to more favorable clinical success rates and fewer complications," said Stanton J. Rowe, Edwards' corporate vice president, Percutaneous Valve Interventions. "Until we gain regulatory approval to allow this option in our trials, we have temporarily suspended U.S. patient enrollment."

Edwards has notified the U.S. Food and Drug Administration of its plans, and simultaneously is working to obtain approvals for this delivery approach. The company believes it will be able to resume its feasibility trial later this year. Previously, Edwards had expected to complete the trial's initial feasibility phase by the end of 2005. Today's announcement is not expected to have a material financial impact to Edwards Lifesciences. Further, company management expressed comfort with the First Call mean EPS estimate for the second quarter of 2005, and reiterated its EPS guidance of $1.90 to $1.95 for the full year.

"We remain confident about the potential of percutaneous heart valve therapies, which offer hope to thousands of patients worldwide who are not good candidates for conventional open-heart valve replacement surgery and face limited options," Rowe said. "At the same time, this is breakthrough medical therapy, and we want to ensure that we provide this technology in a responsible way to patients suffering from debilitating aortic valve stenosis."

About Percutaneous heart Valve Replacement

The Cribier-Edwards percutaneous aortic heart valve is a proprietary technology designed to treat patients with severe aortic heart valve stenosis (a narrowing of the valve that restricts blood flow). Percutaneous heart valve replacement can be performed under local anesthesia without opening the chest or stopping the heart. In a percutaneous heart valve procedure, the device is threaded through the patient's circulatory system via a catheter to the aortic valve from either of two directions. The antegrade approach involves crossing the patient's septum and mitral valve to reach their native aortic valve. The retrograde approach involves delivering the device directly to the aortic valve through the patient's main artery.
