Dennis Troxel, 68, of Gresham, Ore., is the first Oregonian to have his mitral heart valve replaced without open-heart surgery, and is recovering at home from his Feb. 7, surgery. OHSU was the third institution in the U.S. to perform the procedure as part of the APOLLO Trial, which is evaluating the safety and efficacy of Medtronic’s IntrepidTM Transcatheter Mitral Valve Replacement system.
