93 Noninvasive Estimation of Pulmonary Artery (pa) Pressure in Children by Doppler Ultrasonography


Noninvasive means for PA pressure assessment has been sought without a reliable method found. Doppler interrogation of PA flow offers the potential for an easily performed method of estimating PA pressure from changes in velocity patterns. 34 children, ages 1 day-23 yrs (mean 5.3 yrs) with a variety of cardiac abnormalities, underwent simultaneous PA… (More)
