[Double isthmic coarctation of the aorta: "tandem" coarctation].

A second case of double coarctation of the thoracic aorta is reported, the first having been observed at the Marie-Lannelongue Surgical Center in an older child. This case was a 3 months infant in which the missed pre- and postoperative diagnosis led to reoperation after control catheter and angiographic studies. These investigations were carried out one month after the first operation because of persistent severe cardiac failure. Surgical cure in two stages consisted in a Waldhausen plastic enlargement procedure and a Crafoord-type resection anastomosis, ensuring the best chances for a good result.
