Pregnancy outcome in women with Eisenmenger's syndrome: a case series from west China

Background Eisenmenger’s syndrome (ES) consists of pulmonary hypertension with a reversed or bidirectional shunt at the atrioventricular, or aortopulmonary level. The cardiovascular changes that occur during the pregnancy contribute to the high maternal morbidity and mortality in patients with ES. This study is to assess maternal and fetal outcomes in patients with ES. Methods This study is a retrospective analysis of 11 pregnancies in women with ES who delivered at a tertiary care center in west China between 2010 and 2014. Cases were divided into group I (maternal survival) and group II (maternal death). Clinical data were noted and analyzed. Results All ES patients presented with severe pulmonary arterial hypertension (PAH). Four maternal deaths were recorded (maternal mortality of 36%). Only one pregnancy continued to term. Ventricular septal defect diameter in group II was larger than that in group I (2.93 ± 0.76 cm vs. 1.90 ± 0.54 cm, p
