We described a case of a neonate of 13 trisomy with hypoplastic aortic arch and multiple ventricular septal defect (VSD). The patient presented symptoms of congestive heart failure due to pulmonary high flow. Because of ductal patency without prostaglandin infusion, bilateral pulmonary artery banding was performed for regulation of pulmonary high flow. Surgical intervention improved the clinical symptoms of the patient and permitted the patient to be discharged. We concluded that palliative surgery for the patient contributes to improve the quality of life both the patient and the family. This is the 1st report of bilateral pulmonary artery banding for a patient with 13 trisomy.

The Cabrol technique has been used to reimplant coronary arteries at the time of aortic root replacement. We describe a case of coronary stenosis after Cabrol procedure. A 42-year-old female with Marfan syndrome and chronic type B dissection who underwent aortic root replacement with Cabrol procedure complained of chest pain. Computed tomography（ CT） showed extended thoraco-abdominal aortic aneurysm. Angiography revealed bilateral Cabrol limb stenosis at anastomotic sites. Re-do operation was performed under median re-sternotomy. Pannus around the coronary anastomosis was resected and patch extension using bovine pericardium was performed. Reconstruction of coronary arteries was completed by Piehler procedure and total arch replacement with elephant trunk technique was concomitantly performed. Post-operative course was uneventful. CT revealed the release from coronary stenosis.
