The article by F. Fontan and E. Baudet describes a new surgical technique for the repair of tricuspid atresia, which involves creating a double cava-pulmonary anastomosis to ensure that all vena caval blood is directed to the lungs, while only oxygenated blood returns to the left heart. This procedure aims to completely suppress blood mixing, unlike palliative operations that only partially improve clinical symptoms. The technique is not an anatomical correction but a physiological restoration of pulmonary blood flow. The authors report successful outcomes in two out of three patients, with one patient following up for 30 months. The procedure is indicated for children who are well-developed and have normal-sized pulmonary arteries and low pressure. The article also discusses the surgical technique, postoperative complications, and the importance of using valve homografts to prevent free flow between the inferior vena cava, right atrium, and pulmonary artery. The authors conclude that this new technique offers a promising approach for the surgical repair of tricuspid atresia.The article by F. Fontan and E.
