A 10-year-old boy had undergone conventional two-stage surgery that includeed repair of aortic coarctation with pulmonary artery banding as an initial operation followed by closure of a ventricular septal defect as a secondary procedure. Following these procedures, aortic coarctation recurred, and balloon angioplasty was performed three times. Aortic recoarctation, however, persisted, and aortic stenosis and regurgitation and pulmonary stenosis gradually developed. An operation was therefore performed to repair recoarctation, aortic stenosis and regurgitation, and pulmonary stenosis. Patch aortoplasty was performed for recoarctation. The aortic valve was replaced with a 19 mm On-X valve, with Konno root enlargement. Pulmonary arterial patch plasty was also performed. During aortic arch reconstruction, selective cerebral perfusion was performed via the innominate artery and left carotid artery, and the lower half of the body was perfused through a cannula in the left femoral artery. The postoperative course was uneventful, and aortography revealed a well-reconstructed aortic arch free of obstruction. There were no valve-related complications.
