Key Result

The provided text is a tutorial on screencast software and contains no clinical trial data.

Key Points

  • This case examines the use of TAV-in-TAV for treating acute failure of a transcatheter aortic valve in a high surgical risk patient.
  • Patient underwent transfemoral TAVI with a self-expanding prosthesis followed by TAV-in-TAV with a balloon-expandable prosthesis due to acute valve dysfunction.
  • Quick assessment of hemodynamic status and immediate intervention were implemented.
  • Immediate hemodynamic recovery was observed post TAV-in-TAV implantation, resolving acute prosthetic regurgitation.
  • Demonstrated efficacy and safety of TAV-in-TAV as a bailout intervention in high-risk cases.

Structured PICO

Does TAV-in-TAV resolve acute prosthetic failure and hemodynamic instability in a patient undergoing TAVI?

P
Population
82-year-old patient with severe aortic valve stenosis and high surgical risk (chronic renal dysfunction, restrictive lung disease) experiencing acute prosthetic failure immediately after TAVI
I
Intervention
TAV-in-TAV using a 21.5 mm balloon-expandable Myval prosthesis
O
Outcome
Resolution of critical condition and immediate hemodynamic recovery

TAV-in-TAV can serve as an effective and safe bailout intervention for acute prosthetic failure during transcatheter aortic valve implantation.

Abstract

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.
