Why the study?
Pulmonary artery banding has reemerged as a potential strategy for pediatric dilated cardiomyopathy, but comprehensive data on its efficacy and safety remain limited.
Does pulmonary artery banding improve left ventricular ejection fraction and left ventricular end-diastolic diameter z-score in pediatric patients with dilated cardiomyopathy?
Population
175 pediatric patients (<18 years) with dilated cardiomyopathy across 10 studies
Comparison
Pulmonary artery banding
Design
Systematic review and meta-analysis
Key result
Pulmonary artery banding in pediatric dilated cardiomyopathy was associated with a mean increase in left ventricular ejection fraction of 35.3% (95% CI 32.2-38.6) and 81.5% native heart survival.

May support pulmonary artery banding as bridge to recovery in pediatric dilated cardiomyopathy; extends observational data but leaves randomized trials needed.
Meta-Analysis (n=175)
Does pulmonary artery banding improve left ventricular ejection fraction and left ventricular end-diastolic diameter z-score in pediatric patients with dilated cardiomyopathy?
Mean Difference: 35.3 (95% CI 32.2–38.6)
Pulmonary artery banding in pediatric dilated cardiomyopathy is associated with significant left ventricular reverse remodeling and favorable native heart survival, suggesting it may be a promising strategy to delay or avoid heart transplantation.
Guida et al. (2026) conducted a meta-analysis in pediatric dilated cardiomyopathy (n=175). Pulmonary artery banding was evaluated on changes in left ventricular ejection fraction and left ventricular end-diastolic diameter z-score (MD 35.3%, 95% CI 32.2-38.6). Pulmonary artery banding in pediatric dilated cardiomyopathy was associated with a mean increase in left ventricular ejection fraction of 35.3% (95% CI 32.2-38.6) and 81.5% native heart survival.
