Description
Summary:Nonetheless, in principle, bioprosthetic heart valves are often preferred to mechanical valves in that not only do they obviate the need for high-level systemic anticoagulation and the attendant bleeding risks, but also higher rates of prosthetic valve thrombosis have been reported observed in the tricuspid position. The transcatheter tricuspid valve-in-valve (TVIV) procedure has expanded the horizons of cardiac surgery by allowing the implantation of stent-valves within degenerated bioprostheses in older adults and even young patients as the reported rate of the mortality of redo surgery in antecedent studies is at least 37%. Fluoroscopic guidance can assist the operator in implanting a bioprosthetic valve by radiopaque findings in the ideal position and depth; nonetheless, the complete radiolucency of some bioprosthetic valves represents a significant hurdle. In this state-of-the-art manuscript, we decided to deeply explain the appropriate heart-team approach in this scenario.
