Quantitative assessment of pulmonary blood flow redistribution in the classification of group 1 and group 4 pulmonary hypertension.

ABSTRACT:

Background

All patients with pulmonary hypertension (PH), without left heart disease or lung diseases, need further distinguishing between pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). This study aimed to investigate the value of quantitative assessment of pulmonary blood flow redistribution in further classification.

Methods

Forty-six patients who underwent echocardiography and computed tomography pulmonary angiography at The First Affiliated Hospital of Xi'an Jiaotong University were included in this cross-sectional study, and all patients were categorized into a non-PH group (18 cases), a PAH group (12 cases), and a CTEPH group (16 cases). The diameter of the left ventricle and right ventricle were measured. The volumes o
