Efficacy of late First-Trimester Fetal Cardiac Screening (Four Chamber View and Ventricular Outflow Tracts) for detection of cardiac anomalies in a Low-Risk Pregnant women

Background: In Egypt, congenital heart defects (CHDs) are the most prevalent congenital defect and the main reason of newborn mortality. Aim and objectives: to do late first-trimester screening to detect cardiac anomalies in pregnant women (12-14) wks. Mean (13wks). Subjects and methods: This prospective research was carried out on 250 pregnant women coming to the Obstetrics and Gynecology department at Al-Azhar University hospitals of Assiut. The duration of the study ranged from 6-12 months. Result: Meanwhile, high significant differences were found in right and left flow tact between the period from 14 weeks to 22 weeks (pst trimester. Conclusion: The 1st trimester heart ultrasound is meant to help doctors sort out the "normal" pregnancies from the ones that need further examination and the help of a pediatric cardiologist. Assuring expecting mothers that their babies are healthy, conducting short- to medium-term follow-ups in suspicious instances, therapy families affected by cardiac anomalies, offering the possibility of transobstetrical oocyte preimplantation genetic screening (TOPGS) earlier in the pregnancy, and identifying associated chromosomal disorders are all benefits of detecting CHD in the 1st trimester.
