Summary
Transcatheter aortic valve implantation (TAVI) can rarely involve prosthesis displacement. This case highlights successful management by repositioning the dislodged valve and implanting a new one, ensuring patient safety.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
Background:
- Transcatheter aortic valve implantation (TAVI) is a recommended treatment for aortic stenosis.
- Prosthesis embolization or migration is a rare but serious TAVI complication.
Observation:
- An 82-year-old patient experienced prosthesis displacement during TAVI.
- The dislodged prosthesis migrated and was expanded in the descending aorta.
Findings:
- A second prosthesis was successfully implanted in the native aortic valve position.
- Management involved repositioning the dislodged device and implanting a new valve.
Implications:
- Prosthesis dislocation during TAVI requires prompt and effective management.
- Options include repositioning, valve-in-valve procedures, or surgical intervention.
- Technological advancements and operator experience are crucial for minimizing TAVI complications.
