Coarctation of aorta is rather common congenital cardiovascular disease in the western contries, but it is known to be less than 2% in Korea. From June 1986 to December 1992, seven patients of surgically treated coarctation of aorta who were less
than 2
years old, were experienced at Department of Thoracic and Cardiovascular Surgery, Yeungnam University Hospital. The patients included six male and one female, with ages in the range of one month and 24 months. Four patients were preductal type
and
three
juxtaductal. Associated cardiac anomalies were preset in all patients and they were PDA(6 cases), ASD(3), VSD(2), bicuspid aortic valve(2), aortic stenosis(1), mitral regurgitation(1), and tricuspid regurgitation(1). The operative procedures were
four
end to end anastomosis and three subclavian flap aortoplasty. Mean aortic cross clamping times were 37.3 minutes in patients with end to end anastomosis and 30.3 minutes in patients with subclavian flap aortoplasty. There were two operative
deaths
in
patients who were treated with subclavian flap aortoplasty and pulmonary artery banding. One patient who had been treated with subclavian flap aortoplasty was complicated with postoperative mild paraplegia in lower limb. Pulmonary artery banding
has
been disappointing in our patients, and the data was suggestive that earlier total repair of complicated coarctation might improve survival. (Korean J Thoracic Cardiovas Surg 1993;26:604-8)
