Key result
Right atrial reservoir strain <9.4% measured by 2D speckle-tracking echocardiography independently predicted mortality and heart failure hospitalizations in patients with severe TR.
Why the study?
The optimal management of severe TR remains controversial, and the potential prognostic role of RA function in this population is unknown.
Does right atrial function measured by 2D-STE predict mortality and heart failure hospitalizations in patients with at least severe tricuspid regurgitation?
Population
140 patients with at least severe TR, 20 controls, and 20 permanent isolated AF patients
Comparison
Severe TR vs controls and permanent isolated AF patients
Design
Cohort study
Follow-up
Median 2.2 years (IQR: 12–41 months)

May refine risk stratification in severe TR; extends 2D-STE markers but remains hypothesis-generating.

Does right atrial function measured by 2D-STE predict mortality and heart failure hospitalizations in patients with at least severe tricuspid regurgitation?
Right atrial reservoir strain measured by 2D speckle-tracking echocardiography provides independent prognostic value for mortality and heart failure hospitalizations in patients with severe tricuspid regurgitation.
Hinojar et al. (2023) conducted a cohort in Severe tricuspid regurgitation (TR) (n=180). Right atrial function (reservoir strain) by 2D speckle-tracking echocardiography vs. Controls and patients with permanent isolated atrial fibrillation was evaluated on Combined endpoint of hospital admission due to heart failure (HF) or all-cause mortality. Right atrial reservoir strain <9.4% measured by 2D speckle-tracking echocardiography independently predicted mortality and heart failure hospitalizations in patients with severe TR.
