主动脉缩窄是主动脉局部管腔狭窄性病变,常合并室间隔缺损、动脉导管未闭等其他心血管畸形[1],占先天性心脏病的1.1%~14.0%,男性发病率较女性高2~5倍[2-4]。近年来随着超声技术的发展和诊断水平的提高,超声心动图检查在主动脉缩窄的诊断中有重要作用。本组回顾性分析362例主动脉缩窄患儿的超声心动图资料,旨在探讨其超声心动图特点和诊断价值。
Aortic constriction is aortic stenosis, often associated with ventricular septal defect, patent ductus arteriosus and other cardiovascular malformations [1], accounting for 1.1% to 14.0% of congenital heart disease, the incidence of male than women High 2 to 5 times [2-4]. In recent years, with the development of ultrasound technology and the improvement of diagnostic level, echocardiography has an important role in the diagnosis of aortic constriction. This group of retrospective analysis of 362 cases of aortic stenosis in children with echocardiography data to explore its echocardiographic features and diagnostic value.
