An intravascular stent was successfully implanted in a 15-year-old gid with stenosis of the left pulmonary artery subsequent to a modified Fontan correction. Complaints of tiredness, edema, ascites and enlargement of the left breast disappeared. Unfortunately, she died of a rhythm disturbance unrelated to the stent. Autopsy revealed excellent endothelialization of the stent without any thrombosis and with patency of the orifice of the branch to the upper lobe of the lung.
