Abstract: | Valve‐in‐valve (ViV) transcatheter procedures have emerged as a feasible, less‐invasive treatment option for bioprosthetic structural valve deterioration. However, in the presence of a small bioprosthesis, a significant residual gradient after ViV procedures often occurs and has been associated with poorer clinical outcomes. We report the use of the self‐expandable supra‐annular ACURATE neo? valve to treat degenerated Mitroflow (Sorin) aortic bioprosthesis with severe residual elevated gradients followed by valve fracture with a postdilation using a noncompliant balloon leading to significant reduction in residual gradients. In conclusion, the use of ACURATE neo? valve followed by the controlled fracture of the surgical bioprosthesis frame with a noncompliant balloon is a safe and effective approach for patients with Mitroflow® failing valves and residual elevated gradient after transcatheter aortic valve replacement. |
