Late left ventricular myocardial remodeling after pulmonary artery banding for end-stage dilated cardiomyopathy in infants: an imaging study

•PAB has been reinvented as an alternative surgical option for DCM in children.•We examined 7 PAB responders using a structured echocardiographic and CMRI protocol.•Left ventricular remodeling process starts early (30–60 days) after PAB, and ventricular function normalize at about 4-6 months.•1.5-year follow-up CMRI shows sustained favorable left ventricular remodeling.•Areas of myocardial fibrosis were detected by CMRI in all patients.
