  • Data are presented as mean±sd or median (interquartile range), unless otherwise stated. mPAP: mean pulmonary arterial pressure; PVR: pulmonary vascular resistance; PaO2: arterial oxygen tension. Tests of interaction are as follows. mPAP: p=0.975; PVR: p=0.777; PaO2: p=0.317; modified Bruce exercise test: p=0.205; 6-min walking distance: p=0.962. #: versus pre-operative.
