Systolic pulmonary artery pressure derived from pulmonary artery acceleration time could cross-check with pressure derived from simplified Bernoulli Eq.

Abstract

Pulmonary artery pressure measurements are integral to management of pulmonary hypertension. Echocardiographic methods typically make use of blood velocity of tricuspid regurgitation or if tricuspid regurgitation is absent, from other parameters such as acceleration time of blood in the right ventricular outflow tract (RVOT).
