  "abstract": "Introduction: In recent years, there has been rapid development of minimally invasive cardiovascular procedures, such as atrial septal defect (ASD) transcatheter closure. Many female patients of reproductive age have undergone this procedure, but evidence regarding pregnancy outcomes after transcatheter closure of ASD remains limited.\n\nAim: Our aim was to assess maternal and fetal outcomes and investigate the magnitude and determinants of obstetric complications in patients after transcatheter closure of an ASD.\n\nMaterial and methods: We analyzed 130 women with an average age of 28.6 ±9.1 years (19–44) who underwent ASD transcatheter closure using the Amplatzer Septal Occluder. Detailed records of each pregnancy (n = 130), occurring an average of 18.2 ±4.1 months (11–35) after transcatheter closure, were analyzed. Cardiac events were defined as heart failure exacerbation, stroke, transient ischemic attack (TIA), arrhythmias, or endocarditis; obstetric events as pregnancy-induced hypertension (PIH), preeclampsia, HELLP syndrome, premature labor, or postpartum hemorrhage; neonatal events as premature delivery, small-for-gestational age, or fetal or neonatal morbidity or mortality.\n\nResults: Cardiac events were observed during 20.8% (n = 27) of pregnancies and included supraventricular arrhythmias (n = 24, 18.5%) and severe peripheral edema (n = 3, 2.3%). Obstetric events occurred in 22 (16.9%) patients. Neonatal events complicated only 2 (1.5%) pregnancies.\n\nConclusions: Most pregnancies after transcatheter ASD closure with the Amplatzer Septal Occluder were completed successfully, with favorable obstetric and neonatal outcomes. Maternal complications were more common among women aged over 30 years.",
