The data were presented in median (interquartile range) or mean ± standard deviation.
AO = aorta, APE = acute pulmonary embolism, LPA = left pulmonary artery, MPA = main pulmonary artery, PAh = height of the pulmonary artery, PAV = volume of the pulmonary artery, RPA = right pulmonary artery, RVD/LVD = maximal short diameter of the right and left ventricles.
