Key result
TAV-in-TAV with a Myval prosthesis successfully restores hemodynamics in a single case report.
Why the study?
Does TAV-in-TAV resolve acute prosthetic failure and hemodynamic instability in a patient undergoing TAVI?

May support TAV-in-TAV bailout in acute failure; leaves open prospective validation in high-risk patients.
DOI: 10.36660/abcimg.20250111i An 82-year-old patient with severe aortic valve stenosis and high risk for conventional surgery due to chronic renal dysfunction and restrictive lung disease underwent transfemoral transcatheter aortic valve implantation (TAVI) using a self-expanding Navitor ® prosthesis (Abbott). Immediately after implantation, valve dysfunction was observed, characterized by inversion of the right coronary leaflet, resulting in severe acute prosthetic regurgitation and hemodynamic instability. Therefore, a 21.5 mm balloon-expandable Myval ® prosthesis was also implanted (TAV-in-TAV). The critical condition was resolved with immediate hemodynamic recovery. This case demonstrates the efficacy and safety of TAV-in-TAV as a bailout intervention in acute prosthetic failure.
