AB  - PURPOSE OF REVIEW: Transcatheter mitral valve-in-valve (MVIV) implantation is an 
      emerging technique for reoperative mitral valve replacement in high-risk 
      patients. Clear guidelines on the use of transcatheter MVIV implantation are yet 
      to be determined. In this review, we report our own experience as well as the 
      recent available literature on this procedure. RECENT FINDINGS: Since 2010, four 
      case series of three or more patients have been reported with a total number of 
      23 patients. We also include unpublished data of 13 additional patients, who 
      recently had MVIV implantation at our institution. Mean age was 78.45 +/- 9.2 years 
      with a median follow-up ranging from 70 to 357 days. Mean The Society of Thoracic 
      Surgeons (STS) score was 14.1   +/- 7.1%. All patients were in New York Heart 
      Association (NYHA) class III or IV. Thirty days mortality was 7.5% (n = 3) and 
      late mortality was 10% (n = 4). All patients had improvement in postoperative 
      NYHA class to I/II following MVIV implantation. The mitral regurgitation grade 
      was reduced from 3+ or 4+ preoperatively to a grade of 0 or 1 postoperatively. 
      There was no structural valve deterioration reported in the follow-up period in 
      any of the studies. SUMMARY: The available literature supports the use of 
      transcatheter MVIV implantation in selected high-risk patients with favorable 
      results. Although there are no available long-term data on the procedure, the 
      early and mid-term outcomes are excellent with no evidence of structural valve 
      deterioration in the available follow-up period.
