Text: Inhalation of 18 ppm NO reduced the mean (+ / - SE) pulmonary artery pressure (PAP) from 33 + / - 2 to 28 + / - 1 mmHg (p = 0. 008), increased right ventricular ejection fraction (RVEF), as assessed by thermodilution technique, from 28 + / - 2 to 32 + / - 2 % (p = 0. 005), decreased right ventricular end-diastolic volume index from 114 + / - 6 to 103 + / - 8 ml. m-2 (p = 0. 005) and right ventricular end-systolic volume index from 82 + / - 4 to 70 + / - 5 ml. m-2 (p = 0. 009).
