Coarctation of aorta, a well known congenital cardiovascular defect, can be recognized in the most instances by simple finding of physical examination. This condition shortens life if untreated, but it can be corrected surgically to render the patient functionally normal. It seems relatively rare in Asian. During Six-Year period from January, 1982 through June, 1988, twenty four consecutive operations for the coarctation of the aorta were performed at Yonsei Medical Center. The patients included 14 males and 10 females in the range, 2 months and 34 years old. Associated Cardiac anomalies were patient ductus arteriosus, ventricular septal defect, mitral valve regurgitation, aortic stenosis, double outlet right ventricle, corrected transposition of great vessel, etc. The preoperative main symptoms were frequent URI and dyspnea. Congestive heart failure was the most common symptom at the group younger than 2 year olds. Operative techniques for the coarctation of the aorta were prosthetic patch aortoplasty in 18 patients, resection & vascular graft interposition in 4, resection and end to-end anastomosis in 2. There was no operative death. Four patients had persistent or paradoxical hypertension, and one had postoperative paraplegia.
