What is the clinical evidence from this study?

Study design: Review. Population: Atrial functional tricuspid regurgitation.

What does this research mean for the field?

Atrial functional tricuspid regurgitation (AF-TR) is fundamentally a valvular manifestation of underlying right atrial failure and cardiomyopathy, rather than merely a consequence of isolated annular dilation or right ventricular remodeling. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.CHALLENGES_CONSENSUS.

What question did this study set out to answer?

To synthesize mechanistic and clinical evidence establishing atrial functional tricuspid regurgitation as a primary valvular manifestation of right atrial cardiomyopathy and failure.

Key result

Atrial functional TR reflects right atrial failure driven by cardiomyopathy rather than isolated annular dilation.

Why the study?

Atrial functional tricuspid regurgitation is typically described as isolated annular dilation, focusing on a structural end point rather than the underlying pathophysiological substrate of right atrial failure.

Overview

Challenges RV-centric model of functional tricuspid regurgitation in AF; leaves open whether targeting right atrial cardiomyopathy improves outcomes.

Key Points

To synthesize mechanistic and clinical evidence establishing atrial functional tricuspid regurgitation as a primary valvular manifestation of right atrial cardiomyopathy and failure.
Reviewed contemporary structural, functional, and echocardiographic imaging evidence regarding right atrial remodeling and tricuspid annular dynamics.
Evaluated clinical phenotypes, diagnostic approaches for right atrial mechanics, pacing-induced iatrogenic models, and therapeutic targets addressing the atrial substrate.
Right atrial cardiomyopathy—characterized by myocardial fibrosis, electrical instability, and impaired reservoir and conduit mechanics—precedes tricuspid annular enlargement.
Progressive loss of atrial-annular coupling destabilizes tricuspid valve geometry, precipitating functional regurgitation despite preserved right ventricular size and systolic function.
Optimal management requires shifting focus from isolated annular dilation to comprehensive therapies targeting right atrial failure and underlying rhythm disorders.
