Favourable pregnancy outcome in a woman with secondary pulmonary hypertension complicating mitral stenosis.

Pulmonary hypertension (PH) is a rare condition with a high incidence of maternal and perinatal mortality (30-56% and 10-13%, respectively). Pulmonary hypertension is a contraindication to pregnancy because of high risk of maternal death, therefore the World Health Organisation (WHO) advises to discuss a termination in the event of pregnancy with women suffering from PH.
