Basis for intervention on functional tricuspid regurgitation.

Area of Science:

• Cardiology
• Cardiac Surgery
• Valvular Heart Disease

Background:

• Functional tricuspid regurgitation (FTR) is a complex valvular lesion with controversial management.
• It is no longer considered benign and does not resolve spontaneously after left-sided valve correction.
• FTR significantly increases morbidity and adversely affects patient survival.

Purpose of the Study:

• To review emerging concepts and advances in understanding functional tricuspid regurgitation.
• To define the basis for intervention in cases of functional tricuspid regurgitation.
• To address uncertainties in diagnosis, surgical indication, procedure choice, and late surgical outcomes.

Main Methods:

• This is a review article.
• It synthesizes current understanding and emerging concepts in FTR.
• It analyzes the limitations of existing surgical techniques.

Main Results:

• Current repair techniques for FTR often result in significant residual or recurrent regurgitation.
• Failure to address all components of FTR contributes to suboptimal outcomes.
• Optimal management strategies and late results remain areas of active investigation.

Conclusions:

• Functional tricuspid regurgitation is a significant clinical problem requiring careful consideration.
• Advances in understanding are crucial for improving diagnostic accuracy and treatment efficacy.
• Further research is needed to refine surgical indications and techniques for better long-term results.
