Inhaled nitric oxide therapy in pregnancy complicated by pulmonary hypertension,

The use of nitric oxide as an agent to reduce pulmonary artery pressure in a pregnancy complicated by pulmonary hypertension is reported for the first time. This therapy can reduce pulmonary vascular resistance and therefore potentially enable the right ventricle to better compensate for the physiologic changes of pregnancy.
