Eisenmenger's syndrome and pregnancy.

The Eisenmenger's syndrome (E.S.) was redefined by Wood (1958) as pulmonary hypertension with reversed or bidirectional shunt at the aortopulmonary, ventricular or atrial level. This eponym is applicable to 12 different congenital cardiac lesions. Pregnancy in patients with E.S. is a particularly hazardous situation in respect to the prohibitive features of maternal and perinatal mortality (Gleicher et al., 1979; Jones & Howitt, 1965; Neilson et al., 1971).
