Pulmonary artery pressure measurement by echocardiography

Aduen et al performed simultaneous echocardiograms and right heart catheterizations on 117 patients, concluding echo is more accurate and precise than others previously found. They also promote a method of calculating and reporting mean PA pressure on echo, rather than systolic PA pressure. Right heart catheterization remains indispensable as the gold standard.
