Results: Ultrasound scans of 52 fetuses (50 singleton+1 twin) were included in the study. 5 parameters [4CV, V sign, X sign, Tricuspid Doppler (TV), Ductus venosus (DV)] were scored to a maximum of 8 points. Scores <2 were deemed infeasible/ non informative; 3-7 feasible but suboptimal; 8 was optimal. The average time taken for TAS was 15.14 min(95% CI 13.48-16.8;SD 6.04 min); TVS+TAS (n=5) was 24.4 min; multiple sittings (n-6) was 20.5 min. The mean time taken for the scan assuming ideal conditions was found to be 12.8 min (n= 39). Factors affecting optimal imaging were BMI>25 (n=8), previous Caesarean (n=3), multiple fibroids (n=1), fetal position (n=11). Conclusions: Incorporation of fetal echocardiography in first trimester scan protocol helps in identification of a high-risk cohort who can undergo a targeted heart evaluation in the second trimester thereby increasing detection rate of cardiac anomalies.
