“Through this trial, we are investigating a minimally invasive, non-surgical alternative to open-heart surgery for valve replacement in patients with severe aortic stenosis,” said Dr. Adams, who is chair of the Department of Cardiothoracic Surgery at Mount Sinai and is a national co-principal investigator of the CoreValve U.S. clinical trial. “This study will evaluate the safety and efficacy of the CoreValve system for use in the United States, where many thousands of patients are diagnosed with severe aortic stenosis every year.” The CoreValve System is designed with self-expandable technology to replace a diseased aortic valve percutaneously (through the skin), usually through the femoral artery, without open-heart surgery or surgical removal of the native valve. The CoreValve device is delivered through a controlled deployment delivery system.
“We are very excited with this first step in bringing this important transformational therapy to patients in the United States with life-threatening aortic valve disease, particularly those patients who have limited surgical options,” said Jeffrey Popma, M.D., national co-principal investigator of the Medtronic CoreValve U.S. Pivotal Trial and director, Interventional Cardiology at the Beth Israel Deaconess Medical Center in Boston.
About Symptomatic Severe Aortic Valve Stenosis Aortic stenosis is a condition where the aortic valve narrows, thereby limiting blood flow from the aorta to the rest of the body. Untreated, aortic valve stenosis can lead to serious heart problems including heart failure and even death.
Worldwide, approximately 300,000 people have been diagnosed with severe aortic stenosis (100,000 in the U.S.), and approximately one-third of these patients are deemed at too high a risk for open-heart surgery,
i the only therapy with significant clinical effect currently available in the United States.
About the Medtronic CoreValve U.S. Pivotal Clinical Trial The Medtronic CoreValve System with the AccuTrak™ stability layer will be investigated in two independent studies, evaluating patients who have been deemed at high risk for aortic valve surgery, and those who have been deemed at extreme risk for aortic valve surgery (i.e. inoperable). Clinical sites across the U.S. will be identified on www.clinicaltrials.gov. For more information about the Medtronic CoreValve U.S. Clinical Trial, see www.aorticstenosistrial.com.
