Transcatheter valve-in-valve implantation used in elderly patients with degenerated bioprostheses

摘要

The five patients studied by Mortiz Seiffert (University Heart Center, Hamburg, Germany) and colleagues had a mean age of 82.0 ? 6.5 years, and were considered to be high-risk patients owing to their predicted operative mortality calculated at 55.8 ? 18.9%. Each of the patients received a 23-mm Edwards Sapien valve deployed into the degenerated valve prosthesis via transapical access.
