Pulmonary artery pressure estimation by Doppler and two-dimensional echocardiography.
When properly executed, Doppler is a powerful and reliable means of assessing right-heart hemodynamics. Because the Doppler technique depends on ubiquitous functional regurgitant jets, it can confer the benefits of catheterization on the majority of patients having cardiac ultrasound examinations. Progress in ultrasound contrast agents may augment the accuracy of these measurements and enable determination of left-heart hemodynamics.
