Improvement of Hemodynamics and Quality of Life Before and After Interatrial Shunt Devices Implantation for Chronic Heart Failure: A Systematic Review and Meta-analysis.
Synthesis in Current cardiology reviews, 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
introductionThe objective of this study was to compare the quality of life and hemodynamic changes before and after transcatheter atrial septal shunt implantation.
methodsA systematic search was conducted in the Cochrane Library, PubMed, and Embase from inception to September 2023 for studies reporting on hemodynamics or quality of life in patients with chronic heart failure after atrial septal shunt implantation. A meta-analysis was performed, in which a total of 1026 participants from 13 articles were included. RESULTS AND DISCUSSION: Following the implantation, pulmonary capillary wedge pressure (PCWP) decreased by 2.60 mmHg. Right atrial pressure (RAP) increased by 1.30 mmHg and left ventricular ejection fraction (LVEF) increased by 2.13%. However, there were no significant differences in cardiac output and mean pulmonary artery pressure (mPAP) after operation. Minnesota Living with Heart Failure (MLWHF) Score decreased by -19.28, while the Kansas City Cardiomyopathy Questionnaire (KCCQ) score increased by 25.41. Moreover, 6-minute walking distance (6MWD) increased by 32.22 m. The results of subgroup analysis showed that for patients with heart failure with preserved ejection fraction (HFpEF) and heart failure with mildly reduced ejection fraction (HFmrEF), LVEF increased by 3.09% while CO increased by 1.01 L/min after operation. Meanwhile, PCWP significantly decreased by 2.67 mmHg and MLWHF scores decreased by 19.28. Additionally, 6MWD significantly increased by 27.5 m. However, there were no significant changes in RAP and mPAP after operation. For patients with heart failure with reduced ejection fraction (HFrEF), interatrial shunt device implantation did not achieve a significant increase in LVEF.
conclusionThese findings suggest that while atrial septal shunt implantation might not yield LVEF elevation among patients with HFrEF, it improves hemodynamic parameters, exercise endurance, and QoL among individuals with HFpEF/HFmrEF.
