Key result
Cardioversion and rhythm control reverse massive TR to mild with favorable right heart remodeling.
Why the study?
Atrial fibrillation onset is linked to significant tricuspid regurgitation from right atrial and tricuspid annular dilatation, prompting evaluation of rhythm control.
Does rhythm control of atrial fibrillation reduce tricuspid regurgitation severity in patients with atrial fibrillation and severe tricuspid regurgitation?
Case Report (n=1)

Does rhythm control of atrial fibrillation reduce tricuspid regurgitation severity in patients with atrial fibrillation and severe tricuspid regurgitation?
Aggressive rhythm control and restoration of sinus rhythm in patients with atrial fibrillation and severe tricuspid regurgitation can lead to significant reverse remodeling and reduction in regurgitation severity, potentially avoiding the need for valve intervention.

Rhythm control may lessen severe TR in AF; single case leaves open need for prospective trials before practice change.
The onset of atrial fibrillation is associated with the development of significant tricuspid regurgitation in the setting of progressive right atrial and tricuspid annular dilatation. This case demonstrates the positive impact on tricuspid regurgitation of cardioversion and rhythm control of atrial fibrillation.

Lebehn et al. (2025) conducted a case report in Atrial fibrillation and tricuspid regurgitation (n=1). Electrical cardioversion and rhythm control was evaluated on Tricuspid regurgitation severity and right heart remodeling. Electrical cardioversion and rhythm control in a patient with atrial fibrillation and massive tricuspid regurgitation reduced TR severity to mild and improved right heart remodeling over 8 months.
