The retrospective analysis of these images and the relevant clinical records had been approved by the hospital ethics committee. The patients were stratified into one control group without known PH and three groups of patients with progressively more severe PH as quantified by the mean pulmonary artery pressure (mPAP) measured on invasive right heart catheterization [34]: Group 1, 20  mmHg ≤ mPAP &lt;25 mmHg; Group 2, 25 mmHg ≤mPAP ≤30 mmHg; and Group 3, mPAP &gt;30 mmHg.<br>
