摘　　要：目的探讨超声心动图诊断先天性单叶主动脉瓣的价值。方法回顾性分析20例在我院接受超声心动图检查并诊断为单叶主动脉瓣的患者资料。结果20例均出现不同程度主动脉瓣瓣膜功能障碍,其中6例(6/20,30.00%)表现为单纯主动脉瓣狭窄,3例(3/20,15.00%)表现为单纯主动脉瓣反流。2例(2/20,10.00%)为无交界型,舒张期未见关闭线;18例(18/20,90.00%)为交界型,闭合线呈逗点样,附着点多位于1~7点钟位置。17例升主动脉狭窄后扩张。9例伴其他心内畸形,4例有并发症。结论超声心动图可早期诊断先天性单叶主动脉瓣畸形,实时动态显示单叶瓣的几何形态、启闭情况,定量评价其狭窄及反流程度,为选择治疗方式及评估预后提供依据。Objective To explore the value of echocardiography in diagnosis of congenital unicuspid aortic valve(UAV).Methods Totally 20 patients with UAV diagnosed by echocardiography were retrospectively analyzed.Results Valve dysfunction was observed in all 20 patients.Simple stenosis of aortic valve was found in 6 cases(6/20,30.00%),while simple regurgitation was detected in 3 cases(3/20,15.00%).Two cases(2/20,10.00%)showed no attachment point,18 cases(18/20,90.00%)showed attachment point mostly located in 1—7 o'clock.The ascending aorta enlarged after narrowing in 17 cases.Nine cases were found with other congenital heart diseases,while complications were noticed in 4 cases.Conclusion Echocardiography can diagnose congenital UAV at early stage by showing the anatomy and movement of UAV in real time,providing reliable basis for treatment and prognosis assessment.
