CT and echocardiography examinations of PVS rats. A Representative echocardiography of main PA from the sham group. The wave forms in pulsed-wave Doppler mode are triangle shaped. B Representative echocardiography of main PA from the PVS group. The wave forms in pulsed-wave Doppler mode are shaped like the back of a knife. C Quantification of PA acceleration time in the sham and PVS groups, n = 6. D Representative CT from the sham groups. The length of the red line indicates the PV lumen diameter at the banding site. Ao aorta; RPA right pulmonary artery; LPA left pulmonary artery; LA left atrium; PV pulmonary vein; RA right atrium. E Representative CT from the PVS groups. F PA lumen diameter quantification, n = 6
