Pulmonary artery banding may benefit infants with dilated cardiomyopathy. We present the case of an infant with end-stage dilated cardiomyopathy and intractable heart failure who received pulmonary artery banding. Serial follow-up through two-dimensional and three-dimensional echocardiography revealed gradual improvement in the left ventricular ejection fraction and favorable remodeling. The result of three-dimensional speckle tracking suggested that this benefit is associated with improvements in global strain and intraventricular dyssynchrony.
