We describe an infant with duct-dependent hypoplastic left heart complex with moderate hypoplasia of the left ventricle and aortic arch who was not operated due to resource limitations. The left-sided structures grew remarkably due to favourable loading condition changes of the left ventricle, allowing weaning from prostaglandin at the age of 3 months and discharging the patient without intervention.
Keywords: Duct dependent; borderline left ventricle; coarctation; hypoplastic arch; hypoplastic left heart complex; prostaglandin.
