VIGNOLO, Gustavo. Transcatheter valve implantation in dysfunctioning surgical valvular prostheses: a paradigm shift. Rev.Urug.Cardiol. [online]. 2017, vol.32, n.3, pp.277-283. ISSN 0797-0048.

Bioprosthetic surgical valve dysfunction occurs frequently in elderly patients with severe comorbidities, which implies a high surgical risk in case of redo valve surgery. Transcatheter valve implantation within a surgical bioprosthesis, so-called valve in valve procedure (VIV), has been developed as new treatment option for this situation. VIV procedures should be considered in patients with severely symptomatic prosthetic valve dysfunction with high surgical risk, after careful heart team evaluation. Patient selection and pre-procedural evaluation are mainstay for procedural success. Current evidence has stronger support for VIV procedure in aortic than in mitral position. In this review, we briefly analyze VIV procedure indications, patient evaluation, as well as relevant aspects of the procedure itself and its most frequent complications. Special emphasis will be given for VIV in mitral position which has been the focus of two recent case reports in this journal.
