Successful Weaning off LVAD Support in an Infant by Pulmonary Artery Banding.
Article in The Thoracic and cardiovascular surgeon reports, 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: Cardiomyopathy is the leading indication for transplantation in children. Mechanical cardiac support systems play a significant role in treating severe pediatric heart failure for cardiomyoptahy or myocarditis either for recovery or as bridge to transplant. In most cases of chronic heart failure extending over the acute inflammatory phase transplantation is necessary. Organ shortage results in a necessity for further treatment options in terminal heart failure. A new and controversially discussed approach to treat failing (left) ventricles includes pulmonary banding; In some observational studies pulmonary artery banding was performed in patients with severe (left) heart failure and adequate function of the right ventricle. The effect is postulated by improving the contra-lateral (left) ventricular function with intraventricular cross-talk and subsequent myocardial changes. Whereas selected patients may however benefit from PA banding with subsequent training of the left ventricle, nevertheless this strategy is controversially discussed. Case Description: A 3-year-old girl with inflammatory myocarditis required left ventricular assist device (LVAD, Berlin Heart)) support. After repetitive weaning failure, pulmonary artery (PA) banding was performed during LVAD support that resulted in an improvement of the left ventricular function and finally LVAD explantation. Conclusion: Selected patients may benefit from PA banding with subsequent training of the left ventricle even in the setting of LVAD.This case here is the first reported case where PA banding was successful in the weaning process of a child on mechanical circulatory support (MCS). This principle of pulmonary banding to improve left ventricular function in severe heart failure can apparently also be applied to patients on left ventricular assist devices (LVAD).
