Comparative StudyComparison of several noninvasive methods for estimation of pulmonary artery pressure.
Noninvasive estimation of pulmonary artery pressure is an important component of cardiac ultrasound studies. A number of methods are available for estimation of pulmonary pressure, each with varying degrees of reported accuracy. To assess feasibility and accuracy, noninvasive pulmonary artery pressure estimates were performed in infants and children at the time of catheterization. ⋯ For diastolic pressure estimation, systolic time interval records were the most difficult to obtain and did not provide useful accuracy. In contrast, pulmonary regurgitation velocities were easily obtained and provided high accuracy results. This is a selected pediatric series, evaluating methods in nearly ideal circumstances.(ABSTRACT TRUNCATED AT 400 WORDS)
