主动脉缩窄是指主动脉管腔有不同程度的局部狭窄,其部位通常在动脉导管连接于主动脉的区域。本病于1760年由Morgagni首先描述,此后发现其发生率在西方较高,占先心病发生率的5～6%。Abbott报导的1,000例先心病中,主动脉缩窄有178例,发生率高达17.8%。在我国和日本,本病的发生率不如西方高。 Aortic constriction refers to the degree of local aortic lumen stenosis, the site is usually connected to the aorta in the ductus arteriosus area. The disease was first described by Morgagni in 1760 and since then its incidence has been found to be high in the West, accounting for 5-6% of the incidence of CHD. Abbott reported 1,000 cases of congenital heart disease, 178 cases of aortic constriction, the incidence of up to 17.8%. In our country and Japan, the incidence of this disease is not as high as in the West.
