title: Pre-eclampsia and peripartum cardiomyopathy in molar pregnancy: clinical implication for maternally imprinted genes.
abstract: Molar pregnancies are associated with increased maternal complications, notably pre-eclampsia, but peripartum cardiomyopathy has been rarely observed. Here we report on a 34-year-old woman, gravida 2 para 1, who presented to our obstetric clinic for routine screening at 16 weeks of gestation. Elevated maternal serum alpha-fetoprotein and free beta-human chorionic gonadotropin were observed. Amniocentesis revealed a triploid constitution (69,XXX) and ultrasound examination showed growth restriction, fetal anomalies, placentomegaly and a total placenta previa. On admission at 18 weeks' gestation, the patient developed vaginal bleeding and pre-eclampsia. She underwent a Cesarean delivery and 6 h later developed congestive heart failure requiring intensive care support. Molecular analysis of the conceptus and parental DNA demonstrated an excess of paternal genomic contribution. The over-representation of the paternal chromosome complement may support the role of genomic imprinting in the clinical course of this case.
