Color doppler correlates of pulmonary artery hypertension

Abstract

Mild systolic reduction in pulmonary artery flow is an echocardiographic sign of pulmonary artery hypertension. However, at times, it is difficult to appreciate and further grade it into mild, moderate, or severe. We regularly performed color Doppler and color M-mode echocardiography of pulmonary flow and observed that it is easier to interpret and grade the findings. Findings correlate with pulmonary artery pressure evaluated by tricuspid regurgitation jet. Four representative examples are presented.
