Why the study?
Valve-in-valve transcatheter aortic valve replacement has undergone refinements to address procedural challenges such as subpar hemodynamics and coronary obstruction, prompting a review of contemporary techniques and outcomes.
This state-of-the-art review highlights significant procedural refinements and contemporary clinical outcomes for valve-in-valve transcatheter aortic valve replacement in patients with failed bioprostheses.

Refinements may enhance valve-in-valve TAVR safety in failed bioprostheses; extends literature but leaves open need for prospective validation.
Valve-in-valve transcatheter aortic valve replacement is an established alternative to conventional surgical reoperation for failed aortic bioprosthetic valves. The technique has undergone significant refinements in recent years, aiming to tackle pain points of the procedure such as subpar hemodynamics and coronary obstruction. In this state-of-the-art review, we aim to discuss these refinements, including novel surgical valves, transcatheter heart valve positioning, bioprosthetic valve fracture, and prevention of coronary obstruction, among others. We also summarize key updates on clinical trial data and contemporary outcomes of valve-in-valve transcatheter aortic valve replacement.
