Key result
Surgical repair and S-ICD rescue a 28-year-old woman following postpartum cardiac arrest from undiagnosed ASD.
Why the study?
More women with CHD survive to childbearing age, and while most pregnancies are well tolerated, there is a significant risk of potentially fatal complications.

Highlights the risk of potentially fatal complications like postpartum cardiac arrest in women with previously undiagnosed congenital heart disease such as ISV-ASD and PAPVC.
Undiagnosed ISV-ASD may confer postpartum arrest risk; this case leaves open whether targeted screening improves outcomes.
The number of women with congenital heart disease (CHD) surviving to childbearing age is continuously growing. Although most pregnancies in this patient-population are well tolerated, there is a significant risk of potentially fatal complications. We describe a case of a previously completely asymptomatic patient who was diagnosed late during pregnancy with an inferior sinus venosus type atrial septal defect (ISV-ASD) and anomalous connection of all right pulmonary veins (PAPVC) who presented a cardiac arrest with ventricular fibrillation the day after delivery. She recovered completely and underwent subsequent surgical repair and implantation of a subcutaneous defibrillator (S-ICD).

Mbarga et al. (2023) conducted a case report in Postpartum cardiac arrest with uncorrected sinus venosus type atrial septal defect (n=1). Surgical repair and S-ICD implantation was evaluated on Clinical recovery and right ventricular size/function. A 28-year-old woman with an undiagnosed inferior sinus venosus atrial septal defect experienced a postpartum cardiac arrest and successfully recovered following surgical repair and S-ICD implantation.
