CoreValve Transcatheter Valve Approved in Japan

Device found to improve heart failure class, all-cause mortality in more than 90 percent of Japanese patients

April 2, 2015 — Medtronic announced Japanese regulatory approval for the self-expanding transcatheter CoreValve system for patients with severe aortic stenosis (AS). Japanese regulatory authorities granted approval of the CoreValve system for transcatheter aortic valve implantation (TAVI) based on data from the CoreValve U.S. Pivotal Trials and the Medtronic CoreValve Japan Trial, which is the first study to evaluate a self-expandable transcatheter valve in the Japanese patient population.

“We are excited to be able to offer this new option for our patients, as the CoreValve system has demonstrated exceptional clinical results in studies globally as well as in Japan,” said Yoshiki Sawa, M.D., professor in the Department of Cardiovascular Surgery at Osaka University Graduate School of Medicine in Osaka, Japan. “Physicians in Japan should have confidence in making TAVI treatment decisions for patients who may benefit from a less invasive valve replacement procedure with this proven self-expandable valve.”

Data from the Extreme and High Risk Studies in the CoreValve U.S. Pivotal Trial demonstrated that the CoreValve system is safe and effective with high rates of survival and some of the lowest rates of stroke and valve leakage reported. Featuring a supra-annular valve design, the system has also achieved hemodynamics post-implant with results similar to the gold standard, surgical valves.

The Medtronic CoreValve Japan Trial confirmed the performance of CoreValve shown in the U.S. Pivotal Trial. At 6 months, 91.7 percent of the transfemoral patients in the Japan trial met the primary endpoint of improvement of at least one New York Heart Association class and aortic valve area greater than 1.2 cm2. For all patients in the trial, freedom from all-cause mortality at 6 months was 90.8 percent. The trial also demonstrated functional and anatomical effectiveness of CoreValve.

The CoreValve self-expanding nitinol frame enables physicians to deliver the device to the diseased valve in a controlled manner, allowing for accurate placement. Valves are delivered via the smallest (18Fr, or approximately 1/4 inch) TAVR delivery system available, making it possible to treat patients with difficult or small vasculature.

The device is indicated for patients with severe AS unable to undergo surgery, and for whom treatment with the CoreValve is determined to be the best option.
