Outcomes of Worsened Left Ventricular Ejection Fraction After Transcatheter Aortic Valve Replacement.
Article in International journal of general medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Left ventricular ejection fraction (LVEF) worsening after transcatheter aortic valve replacement (TAVR) was common in clinical practice. However, the effect of acute worsening LVEF is unclear. Methods: All consecutive patients who underwent TAVR between January 2016 and May 2022 were analyzed. Patients were divided into worsened LVEF and non-worsened LVEF according to whether or not they had an LVEF decline of ≥5% at discharge. Survival at follow-up was compared between two groups. Logistic regression analysis was used to determine independent predictors of worsening LVEF. Results: A total of 439 patients were included in the analysis, and 112 (25.5%) patients had worsened LVEF. Worsened LVEF was more common in patients with LVEF ≥50%. After multivariable logistic analysis, only baseline LVEF was associated with worsening LVEF [OR=1.06 (95% CI: 1.04-1.08), P < 0.001]. The decline in LVEF recovered to the baseline after one month. There were no significant differences in survival between patients with and without worsened LVEF (Log rank P = 0.48). Conclusion: Acute worsening of LVEF after TAVR was not uncommon but did not affect survival. It could recover to baseline levels after one month. Routine post-TAVR echocardiography should focus on other metrics rather than acute LVEF changes.
