Abstract

In the Taiwanese literature, few articles describe the pertinent features of aortic stenosis (AS). This study explores the features of AS in Chinese children. 3808 children with congenital heart diseases have undergone cardiac catheterization at our institution over the past 19 years. Among them, 51 (1.3%) cases were AS. The clinical, electrocardiographic, echocardiographic and catheterization findings, the methods of treatment and outcomes were reviewed. Valvular AS occurred in 39 children (76.5%), subvalvular AS in 5 (9.8%), and supravalvular AS in 7(13.7%). Male was predominant (M/F ratio, 2.6) except in supravalvular type. Forty-three patients had associated cardiovascular defects. Aortic regurgitation (AR) was the most common one. Most patients (56.9%) were asymptomatic. Classic symptoms included exertional dyspnea (17.6%), syncope (9.8%), and chest pain (7.8%), etc. Left ventricular hypertrophy was noted in 31.2% of cases. The mean duration of follow-up was 3.9 +/- 3.4 years. Ten patients received open-heart surgery and 2 received balloon dilation. The pressure gradients across the stenotic area dropped from 95.3 +/- 29.3 to 51.4 +/- 35.8 and 53.1 +/- 12.3 mm Hg in early and late Doppler follow-up studies, respectively (p...Continue Reading
