A 14 month old child presented for investigation of tachypnoea.
No parenchymal lung disease was shown on chest
x ray. On echocardiography there was normal
intracardiac anatomy with significant pulmonary hypertension. At
cardiac catheterisation the presence of primary pulmonary hypertension
was confirmed, with a partial response to inhaled nitric oxide (80 ppm)
and 100% oxygen. The child was referred for assessment for heart-lung
transplantation while maintained on oxygen, inhaled nitric oxide, and
nifedipine. Repeat cardiac catheterisation two months after
presentation showed complete normalisation of the pulmonary artery pressures.
