Because of its rarity, the differentiation of this anomaly from other tricuspid valve dysplasias is difficult. Tricuspid regurgitation is the hallmark of Ebstein's anomaly and other tricuspid valve abnormalities, whereas in unguarded tricuspid orifice there is total absence of the valve, resulting in \u2018to and fro\u2019 flow across the right\u2010sided chambers. The color Doppler flow pattern helps in differentiating this anomaly from others. The antenatal diagnosis was confirmed on autopsy. Copyright \u00a9 2005 ISUOG.
