Doppler Echocardiography in Pulmonary Stenosis

Doppler ultrasound has dramatically improved the accuracy of noninvasive detection of pulmonary stenosis. Combined with careful two-dimensional imaging, the site and severity of obstruction to pulmonary flow can be detected and quantified. Although there are some limitations to the technique, interpretive errors are avoidable with an understanding of the method and careful attention to detail during the performance of the examination. Doppler echocardiography has become a valuable adjunct to the nonsurgical treatment of valvular pulmonary stenosis and promises to provide more information for developing new management schemes in congenital heart disease.
