A 13-year-old boy underwent corrective surgery of CoA + VSD + PH at 50-day. Vascular murmur and hypertension was present so that he was admitted to our hospital. Systemic pressure was 164/106 mmHg (right arm) and systolic blood pressure at right leg was 70 mmHg. The systolic pressure gradient was 94 mmHg. The intracardiac pressure was within normal limit and there was no shunt. And the stenosis of descending aorta was present at the distal of subclavian branch and that pressure gradient was 76 mmHg. The diagnosis was established recurrent coarctation and operation was performed. The recurrent coarctation was 8 mm in diameter and longitudinal incision was made and woven Dacron patch aortoplasty was done. Aortic cross clamping time was 43 minutes. Postoperative clinical course was smooth. At 4 weeks after aortography was performed and no appreciable stenosis of the descending aorta was revealed. The pressure gradient decreased from 76 mmHg to 11 mmHg.
