We prospectively assessed the effects of the MitraClip procedure in 81 patients with or without pulmonary hypertension (defined as mean pulmonary artery pressure &gt;\u00a025\u00a0mmHg), who were anaesthetised using fentanyl (5\u00a0\u03bcg.kg\n                    <jats:sup>\u22121<\/jats:sup>\n                    ), etomidate (0.2\u20130.3\u00a0mg.kg\n                    <jats:sup>\u22121<\/jats:sup>\n                    ), rocuronium (0.5\u20130.6\u00a0mg.kg\n                    <jats:sup>\u22121<\/jats:sup>\n                    ) and isoflurane. Placement of the MitraClip led to a 60% increase in mean (SD) right ventricular stroke work index (from 512 (321) to 820 (470)\u00a0mmHg.ml.m\n                    <jats:sup>\u22122<\/jats:sup>\n                    , p\u00a0&lt;\u00a00.0001), while mean (SD) pulmonary vascular resistance index decreased by 24% (522 (330) to 399 (244)\u00a0dyn.s.cm\n                    <jats:sup>\u22125<\/jats:sup>\n                    , p\u00a0&lt;\u00a00.0001), and mean (SD) pulmonary artery pressure decreased by 10% (30 (8) to 27 (8)\u00a0mmHg, p\u00a0&lt;\u00a00.0001). Patients with pulmonary hypertension experienced a similar decrease in mean pulmonary artery pressure compared with those without, and they also had a slight reduction in mean (SD) pulmonary artery occlusion pressure (22 (6) down to 20 (6)\u00a0mmHg, p\u00a0=\u00a00.044).
