摘　　要：目的基于超声心动图观察儿童单纯二叶式主动脉瓣(i-BAV)表现。方法回顾性分析79例i-BAV患儿超声心动图,观察其i-BAV分型;根据有无瓣膜和/或主动脉受累分为并发症组(n=50)与无并发症组(n=29),比较组间超声心动图参数。结果经体表面积(BSA)校正后,并发症组左心室收缩末期内径/BSA低于、而左心室心肌质量指数高于无并发症组(P均<0.05)。79例中,Type 0型22例、以lat亚型最多见(18/22,81.82%),TypeⅠ型57例、以L-R亚型最多见(39/57,68.42%)。并发症组以TypeⅠL-R亚型最多见(31/50,62.00%);瓣膜受累发生率为90.00%(45/50),以轻度主动脉瓣狭窄和/或关闭不全为主(37/45,82.22%);主动脉受累发生率为24.00%(12/50),均表现为Ⅰ、Ⅱ型主动脉增宽。结论儿童i-BAV最常见分型为TypeⅠL-R亚型,以轻度瓣膜损害为主要并发症,可存在左心室心肌重构。Objective To observe the manifestations of isolated bicuspid aortic valve(i-BAV)in children using echocardiography.Methods Echocardiographic data of 79 children with i-BAV were retrospectively analyzed,and classification of i-BAV was performed.The patients were divided into complication group(n=50)and non-complication group(n=29)according to the existence of valve and/or aortic involvement or not,and echocardiographic parameters were compared between groups.Results After adjusting body surface area(BSA),in complication group,left ventricular end-systolic diameter/BSA was lower,while left ventricular myocardial mass index group was higher than those in non-complication group(both P<0.05).Type 0 i-BAV was found in 22 cases,with lat subtype as the most common ones(18/22,81.82%),while TypeⅠwas observed in 57 cases with L-R subtype as the most common ones(39/57,68.42%).The most common subtype in complication group was also TypeⅠL-R(31/50,62.00%),with incidence of valve involvement of 90.00%(45/50),mainly including mild aortic stenosis and/or incompetence(37/45,82.22%),and incidence of aorta involvement of 24.00%(12/50),all with typeⅠorⅡaortic widening.Conclusion The most common subtype of i-BAV in children was typeⅠL-R,with mild valve damage as the main complication and possibility of left ventricular myocardial remodeling.
