Transcatheter tricuspid valve replacement in dehisced flexible ring

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Reoperation on the tricuspid valve carries high mortality.
• Surgical tricuspid annuloplasty repairs have a considerable failure rate over time.
• Transcatheter valve-in-ring presents an alternative to repeat surgery.

Observation:

• A case of transcatheter tricuspid valve-in-surgical annuloplasty ring implantation is presented.
• The patient had a flexible tricuspid ring with significant dehiscence.
• The procedure was performed successfully in this challenging scenario.

Findings:

• Transcatheter valve-in-ring is a feasible option for specific tricuspid valve conditions.
• Successful implantation was achieved despite significant ring dehiscence.
• The procedure avoided high-risk tricuspid valve reoperation.

Implications:

• This approach may improve outcomes for patients with degenerated tricuspid annuloplasty rings.
• Careful procedural planning is crucial for managing potential complications like paravalvular leaks.
• Understanding complex 3D cardiac anatomy is essential for successful transcatheter interventions in this setting.
