  • *Data were missing in three cases.

  • †Obstetrical management data were unknown for one patient.

  • ‡One patient delivered without any anaesthesia, and two modes of anaesthesia were missing in the group without cardiac complication. We have not compared data of obstetrical management because of their small number in each category.

  • BMI, body mass index; CHD, congenital heart disease; NYHA, New York Heart Association; PAH, pulmonary arterial hypertension.
