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.
