Key result
Transcatheter tricuspid annuloplasty safely reduces annular dimensions and TR severity, improving clinical symptoms.
Why the study?
New transcatheter techniques for tricuspid annuloplasty are evolving and being introduced into clinical routine, but clinical experience remains limited.
Transcatheter tricuspid annuloplasty is an emerging, safe, and effective therapy for tricuspid regurgitation, though long-term data is still needed.
PURPOSE OF REVIEW: New transcatheter techniques to perform tricuspid annuloplasty are evolving and are introduced into the clinical routine. Yet, clinical experience is limited. RECENT FINDINGS: Currently, 3 different techniques for tricuspid annuloplasty have been used in larger clinical cohorts. They can be divided into direct annuloplasty techniques and suture plication techniques. The largest clinical evidence is related to direct annuloplasty techniques. It has been shown that annular dimensions can be effectively reduced. This translates into an improvement of the degree of tricuspid regurgitation and improvement of clinical symptoms. Due to the newness of this type of therapy, long-term data is limited, but for one of the described techniques, published data show that the positive effects persist over a 2-year period. Transcatheter approaches are safe and are able to treat tricuspid regurgitation effectively. There are still differences in the efficacy of the different techniques. Clinical experience varies among the different approaches.

Arnold et al. (2021) conducted a review in Functional tricuspid regurgitation. Transcatheter tricuspid annuloplasty was evaluated. Transcatheter tricuspid annuloplasty techniques are safe and effectively reduce annular dimensions and tricuspid regurgitation severity, leading to clinical symptom improvement.
