Trans-catheter valve-in-valve implantation with a novel balloon expandable device in patients with bioprosthetic heart valve failure: A case series.

Trans-catheter valve-in-valve (ViV) is a treatment option for patients affected by bioprosthetic heart valve (BHV) failure. Both aortic and mitral ViV procedures present several challenges compared to native valve replacement. To date, no data concerning the balloon-expandable MyVal (Meril, Vapi, India) trans-catheter heart valve (THV) use in ViV procedure have been provided. In this case series, we described for the first time its use in five different BHV failures.
