Association of Right Ventricular-Pulmonary Arterial Coupling and Progression of Tricuspid Regurgitation in Patients With Atrial Fibrillation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTricuspid regurgitation (TR) severity is associated with poor prognosis in patients with atrial fibrillation (AF). Recently, right ventricular-pulmonary arterial (RV-PA) coupling has been shown to be related to clinical outcomes in patients with TR. However, data on the relationship of RV-PA coupling to the progression of significant TR are limited. This study aimed to investigate whether RV-PA coupling affects the progression of significant TR in patients with AF.
methodsAmong 664 patients with AF who underwent follow-up echocardiography at least 6 months after the initial assessment, 484 consecutive patients with AF (mean age 68±12 years, 38% women) with insignificant TR were included. RV-PA coupling was assessed by the ratio of RV 4-chamber strain measured through speckle tracking echocardiography to pulmonary artery systolic pressure (PASP).
resultsOver a mean 3.6±2.7 years of follow-up, 46 (9.5%) patients have progressed to significant TR, at least a moderate degree. Patients who progressed to significant TR were older, more likely to be women, had higher E/eꞋ and PASP, lower RV4CSL and RV 4-chamber strain /PASP compared with patients without TR progression. RV-PA coupling, reflected by RV 4-chamber strain/PASP, was independently associated with the progression of TR even after adjusting for age, sex, and E/eꞋ (
conclusionsIn patients with AF, RV-PA coupling was independently associated with the progression of TR, suggesting that it may be helpful in monitoring this population.
