Survival over 80% after valve-in-valve implantation

For patients with failed surgical bioprosthetic valves, one-year survival after transcatheter valve-in-valve implantation is 83.2%, according to a study published in the July 9 issue of the Journal of the American Medical Association.

Danny Dvir, MD, from St. Paul's Hospital in Vancouver, Canada, and colleagues examined the survival of patients after transcatheter valve-in-valve implantation inside failed surgical bioprosthetic valves. Data were obtained from a multinational valve-in-valve registry that included 459 patients (mean age: 77.6 years) with degenerated bioprosthetic valves undergoing valve-in-valve implantation at 55 centers.
