Abstract:
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.
