Study Examines Survival Following Repair of Failed Bioprosthetic Aortic Valves

In an analysis of about 460 patients with failed bioprosthetic aortic valves who underwent transcatheter valve-in-valve implantation, overall survival at one year was 83 percent, with survival associated with surgical valve size and mechanism of failure, according to a study. Surgical aortic valve replacements increasingly use bioprosthesis implants rather than mechanical valves. Owing to a considerable shift toward bioprosthesis implantation, it is expected that there will be an increase in the number of patients with degeneration of these types of valves.
