[Quantitative Doppler echocardiography diagnosis of congenital aortic and pulmonary artery stenoses].
The aim of the present study was to check the value of cw-Doppler echocardiography for the assessment of severity of congenital aortic and pulmonary stenoses in children and adolescents. Over a period of 3 years 217 children and adolescents with aortic and 98 with pulmonary stenosis, resp., underwent echocardiography. In 21 patients with aortic and in 23 with pulmonary stenosis pressure gradients were determined by cw-Doppler as well as intracardiac pressure measurement. The comparison showed excellent accordance between both sorts of data for aortic stenoses (r = 0.939) and pulmonary stenosis (r = 0.969). These results show that Doppler echocardiography is a reliable diagnostic method for the determination of pressure gradients. Thus, it allows correct selection of children and adolescents with aortic stenosis for surgery. So far, 12 patients have been operated on without preoperative cardiac catheterization. Indication for balloon valvuloplasty in patients with valvular pulmonary stenosis can be based safely on 2 D- and Doppler echocardiography.
