Use of noninvasive cardiac ultrasound techniques in quantitation of pulmonary artery (PA) blood flow and pressure has been reported in several studies.1–6 This study examines temporal indexes of PA flow in 8 children with idiopathic PA hypertension and pulmonary vascular resistance of 12 units/m2 or more.
