This case was referred to us for second trimester anomaly scan. At some other diagnostic centre, it was misreported as query dextrocardia and the obstetrician referred to us for second opinion.
When I scanned the fetus, I found that the apex of heart is cleary towards left side. Since, the size of right ventricle is very small, it gives false impression that the apex of heart is reversed. So, one can confidently say after careful observation that its levocardia.
The tricuspid valve is atretic and there is no blood flow across the right atrio-ventricular junction. Consequently, the right ventricle has become very small in size. Right ventricle is getting filled by left ventricle through the ventricular septal defect. Moreover, the right atrium is dilated and there is widening of foramen ovale. So, its a classic but very rare case of TRICUSPID ATRESIA WITH HYPOPLASTIC RIGHT VENTRICLE.
