Abstract
The development of transcatheter valve implantations (TAVI) has induced profound changes in the treatment of valvular heart disease over the past decade. At the same time, due to excellent clinical results, bioprostheses continuously outperformed mechanical prostheses. The increasing number of elderly patients has led to numerous patients presenting with deteriorated bioprostheses needing reoperation. In selected high-risk patients or patients with unreasonable surgical risk, valve-in-valve TAVI has advanced to a viable alternative to conventional redo surgery. High procedural success, good hemodynamics and acceptable clinical results were reported up until now. Valve-in-valve TAVI seems to be safe and effective in treatment of deteriorated valve prostheses in high-risk patients. The valve-in-valve concept presents the next step toward an individual treatment strategy for patients at prohibitive risk for conventional surgery. Present studies were reviewed with special concern to patient selection, prosthesis assessment, device selection, clinical outcome and technical challenging aspects as well.
