Innovative Approach to Manage Transcatheter Aortic Valve Embolization

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Medical Device Technology

Background:

• Ascending aortic aneurysms pose significant surgical risks.
• Transcatheter aortic valve implantation (TAVI) is an established treatment for aortic valve disease.
• Valve-in-valve TAVI presents unique challenges, including potential device complications.

Observation:

• A patient undergoing valve-in-valve TAVI for an ascending aortic aneurysm experienced acute valve embolization.
• The embolized valve became free-floating within the aorta.
• Standard retrieval or repositioning techniques were not immediately feasible.

Findings:

• A multidisciplinary team devised an innovative solution to manage the embolized valve.
• An uncovered aortic endovascular stent was utilized to anchor the free-floating valve.
• The endovascular stent successfully secured the embolized valve in the aortic arch, resolving the complication.

Implications:

• This case demonstrates a novel approach to managing valve embolization during TAVI.
• The use of aortic endovascular stents offers a potential salvage strategy for complex TAVI complications.
• This technique may expand treatment options for patients with challenging aortic anatomies and valve implantation issues.
