Abstract

Background: While the 1st trimester of pregnancy is essential to organogenesis, it also carries the risk of an elevated complication rate. The detection of fetal cardiac activity is the first indication of a healthy pregnancy. The gestational sac is the first detectable sign of pregnancy by ultrasound.

Aim and objectives: To evaluate gestational sac diameter (GSD) and embryonic heart rate (EHR) & to determine if these parameters may be utilized as prognostic indicators for the pregnancy outcome in the 1sttrimester.

Subjects and methods: This prospective observational investigation was conducted at the Obstetrics and Gynecology Department at Al-Hussein University Hospital on 76 cases of singleton pregnancies within gestational age from 6-12 weeks.

Result: Fetal heart rate showed a significant reduction in the miscarriage group contrasted with the normal pregnancy group (p

Regarding Gestational Sac Size (mm), the AUC was 0.741, the Cutoff value was 33, the Sensitivity was 78%, and the Specificity was 76.9%. Regarding Heart Rate (Bpm), the AUC was 0.822, the Cutoff value was 126, the Sensitivity was 81.4%, and the Specificity was 84.6%.

Conclusion: Regardless of maternal risk variables like age, body mass index (BMI), or parity, abnormal GSD (small, inflated, nonexistent, or uneven yolk sac) and embryonic bradycardia have been related to a poor pregnancy outcome
