1 · What the graph read from it

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.

2 · The registry

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

backgroundSecondary mitral regurgitation is associated with adverse clinical outcomes and cardiac remodeling. While transcatheter edge-to-edge repair (TEER) improves symptoms and prognosis in selected patients, its effects on cardiac remodeling remain debated. This systematic review and meta-analysis aimed to evaluate the impact of TEER on echocardiographic indices of cardiac remodeling.

methodsPubMed, Scopus, and Cochrane Library were used to identify relevant studies assessing echocardiographic changes before and after TEER. Outcomes of interest were left ventricular (LV) ejection fraction, global longitudinal strain, LV end-diastolic and end-systolic volumes and LV end-diastolic and end-systolic diameter, tricuspid annular plane systolic excursion, pulmonary artery systolic pressure, and left atrial end-systolic volume.

resultsForty-two studies (3987 patients) were included. TEER was associated with a significant increase in LV ejection fraction (mean difference [MD], 1.51% [95% CI, 0.47-2.55]), without significant improvement in global longitudinal strain. Significant LV remodeling was observed, with reductions in LV end-diastolic volume (standardized MD, -0.26 [95% CI, -0.37 to -0.14]), LV end-systolic volume (standardized MD, -0.21 [95% CI, -0.30 to -0.12]), LV end-diastolic diameter (MD, -2.35 mm [95% CI, -3.66 to -1.04]) and left ventricular end-systolic diameter (MD, -2.30 mm [95% CI, -3.86 to -0.74). TEER also improved right ventricular function (tricuspid annular plane systolic excursion [MD, 1.29 mm [95% CI, 0.60-1.97]) and reduced pulmonary artery systolic pressure (MD, -6.75 mm Hg [95% CI, -8.53 to -4.97). No significant improvement in left atrial end-systolic volume was detected.

conclusionsAvailable evidence suggests that TEER promotes significant cardiac remodeling in patients with secondary mitral regurgitation.
