Purpose: To assess the diagnostic accuracy and features of Echocardiography on congenital valvular aortic stenosis (VAS) and subvalvuar aortic stenosis (SVAS) in children. Methods: The echocardiographic characteristics of 12 patients diagnosed VAS and SVAS were analyzed and compared with results of operation results. Results: 3 of total 12 patients were diagnosed subvalvuar aortic stenosis, 6 were diagnosed valvuar aortic stenosis, 3 subvalvuar aortic stenosis cases were associated with valvuar aortic stenosis. The echocardiographic characteristics of VAS were correspondent to the results of operation findings in 12 patients except 2 patients had mismatch of preoperative diagnosis and intraoperative findings. Conclusion: The differential diagnosis of VAS and SVAS is important for surgery. There is high accuracy of echocardiography in the diagnosis of VAS and SVAS in children.
