Single-ventricular cardiopathies are challenging conditions requiring multiple surgical interventions to hopefully achieve adulthood. In neonates, pulmonary artery banding allows ventricular adaptation and pulmonary vascular bed protection. Here we present a novel minimally invasive approach to pulmonary artery banding through a 1.5 cm left parasternal minithoracotomy. This technique not only allows for a less traumatic first procedure but also a less manipulated mediastinum and untouched sternum for the consequent surgeries to come. This technique is reproducible in experienced hands and shows favorable and promising results when performed properly.
