Abstract:
Transcatheter aortic valve implantation (TAVI) within failed bioprosthetic surgical aortic valves (valve-in-valve TAVI) has become an established procedure, currently approved for patients deemed at high risk for repeat aortic valve intervention. Although less invasive than surgical reoperation, challenges of valve-in-valve treatment include higher rates of malposition, prosthesis-patient mismatch and coronary obstruction. Thus, optimal patient selection and preprocedural planning is of the utmost importance to minimise the risk of these complications. In this review article we provide a fully illustrated overview of the most significant periprocedural operative considerations for valve-in-valve TAVI.
