Conclusion:
Tricuspid regurgitation is the hallmark finding in Ebstein’s anomaly and other tricuspid valve disorders, whereas in partial absence of TV leaflets results in ‘to and fro’ flow across the right sided chambers. Severe TV regurgitation leads to compromised forward flow in to the pulmonary artery resulted in smaller main pulmonary artery in this case. The Color Doppler flow pattern helps in differentiating this anomaly from others. Hence precise sequential segmental evaluation of the fetal heart is of significant importance. Four-dimensional spatiotemporal image correlation rendering provides incremental benefit in evaluation of TV anomalies. This will help in counselling parents about the expected pregnancy outcome.
