A 26-year-old patient, who has double inlet left ventricle, pulmonary atresia, and a patent vertical arterial duct, presented with progressive cyanosis with an arterial oxygen saturation of 71%. He had had three shunt operations and only the last aortopulmonary shunt was patent. Angiography revealed a stenotic aortopulmonary shunt, stenotic vertical arterial duct, and a branch stenosis of the left pulmonary artery. He underwent successful stent implantation into both the aortopulmonary shunt and vertical arterial duct and his arterial oxygen saturation increased to 88%. This case report illustrates that stent implantation into a vertical arterial duct is feasible and can be an alternative to shunt operation.
