Medtronic plc announced the U.S. Food and Drug Administration (FDA) approval and U.S. launch of the CoreValve(TM) Evolut(TM) R 34 mm valve-the largest sized transcatheter aortic valve replacement (TAVR) system available in the U.S. The new Evolut R 34 mm valve is approved for severe aortic stenosis patients who are at high or extreme risk for surgery with an annulus size ranging from 26-30 mm. This large valve segment is estimated to account for approximately 25-30 percent of the eligible global TAVR patient population. Previously, some of these patients were unable to receive a TAVR due to the larger size of their native diseased aortic valve.
