Echocardiography-guided transcatheter closure of atrial septal defects for three pregnant women / 中华围产医学杂志

ABSTRACT

Objective:To investigate the feasibility of echocardiography-guided transcatheter closure of atrial septal defect (ASD) during pregnancy and summarize the multidisciplinary treatment experience for such women.Methods:A retrospective analysis was performed on three women receiving echocardiography-guided secondum ASD closure during pregnancy in Guangdong Provincial People's Hospital from January 2018 to October 2021. Perioperative and perinatal multidisciplinary treatment and prognosis were described.Results:All three patients underwent cardiac ultrasonography due to abnormal electrocardiogram during routine prenatal examination and were diagnosed with secondum ASD. Progressive cardiac dysfunction was found during close follow-ups and all cases met the criteria for ASD closure during pregnancy after multidisciplinary evaluation. Echocardiography-guided ASD closure was successfully performed in all patients. Pulmonary arterial pressure was significantly reduced and the cardiac function was stable after the operation. All patients delivered vaginally at term without complications such as miscarriage, premature birth, postpartum hemorrhage or fetal growth restriction and had their cardiac function recovered during postpartum follow-up.Conclusions:Echocardiography-guided ASD closure during pregnancy is technically feasible. Good maternal and fetal outcomes can be obtained through multidisciplinary and close monitoring and treatment during perioperative and perinatal periods.
