| 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%),Type Ⅰ型57例、以L-R亚型最多见(39/57,68.42%)。并发症组以Type Ⅰ L-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Type Ⅰ L-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 Type Ⅰ was 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 Type Ⅰ L-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 type Ⅰ or Ⅱ aortic widening. Conclusion The most common subtype of i-BAV in children was type Ⅰ L-R, with mild valve damage as the main complication and possibility of left ventricular myocardial remodeling. |
