Tricuspid Annuloplasty: Transcatheter Approaches

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Medical Device Technology

Background:

• Transcatheter tricuspid annuloplasty techniques are evolving for clinical use.
• Limited clinical experience exists for these novel procedures.

Purpose of the Study:

• To review current transcatheter techniques for tricuspid annuloplasty.
• To summarize recent findings on their efficacy and safety.

Main Methods:

• Review of clinical data from larger cohorts using 3 distinct transcatheter tricuspid annuloplasty techniques.
• Categorization into direct annuloplasty and suture plication methods.

Main Results:

• Direct annuloplasty techniques show the most extensive clinical evidence.
• Effective reduction in annular dimensions, leading to improved tricuspid regurgitation and symptoms.
• Positive effects demonstrated to persist for at least 2 years with one technique.

Conclusions:

• Transcatheter tricuspid annuloplasty is a safe and effective treatment for tricuspid regurgitation.
• Differences in efficacy exist among techniques, necessitating further clinical experience.
