Obstruction area ratio. a. The central pulmonary artery was reconstructed into four sections: main pulmonary artery trunk, MPA triangular section, and left and right pulmonary arteries. b. The central pulmonary artery was reconstructed together with the embolism

c and d. The maximal obstruction area ratio at the right and left pulmonary was calculated as half of the total maximal obstruction area ratio at the right pulmonary artery section and the left pulmonary artery section (A: aorta; RV: right ventricle; LV, left ventricle; RA, right atrium; LA, left atrium; LPA, left pulmonary artery; RPA, right pulmonary artery). The The obstruction area ratio was calculated as half of the total maximal obstruction area ratios perpendicular to long-axis of right and left pulmonary arteries as c and d
