Pulmonary artery banding for dilated cardiomyopathy in children: report of 3 cases.
Article in BMC pediatrics, 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
backgroundPulmonary artery banding (PAB) has emerged as a promising surgical treatment for pediatric dilated cardiomyopathy (DCM) in recent years. However, clinical evidence supporting its efficacy remains limited. This study reports on three cases with DCM treated with PAB to evaluate its short-term therapeutic outcomes. CASE PRESENTATION: Clinical data were collected from three children diagnosed with DCM and admitted to our hospital. Case 1 had congenital aortic arch hypoplasia (AAH) and developed progressive left ventricular (LV) enlargement in infancy. Case 2 and case 3 were initially diagnosed with endocardial fibroelastosis (EFE). All three patients had previously received standard medical therapy, but experienced progressive cardiac enlargement and declining function. Preoperative left ventricular ejection fraction (LVEF) was 25% in Case 1, 21% in Case 2 and 44% in Case 3. Each patient underwent preoperative echocardiography and cardiac magnetic resonance imaging (CMR), following by surgical PAB and postoperative monitoring. All three children were discharged in stable conditions and demonstrated favorable short-term recovery. Case 1 and 3 exhibited improvements in LVEF of over 20% compared to preoperative values, along with reversal of left heart - suggesting the potential for myocardial reverse remodeling. Case 2 showed marginal improvement with stabilization of LV dilation during follow-up of 4-months.
conclusionPulmonary artery banding appears to be a valuable therapeutic option for pediatric DCM, particularly in patients where heart transplantation or mechanical circulatory is not feasible. Further studies with larger cohorts and longer follow-up are needed to confirm its long-term efficacy. CLINICAL TRIAL NUMBER: Not applicable.
