A 22-year-old woman (G1P0) with non-contributive history was sent to our office at 12 weeks + 1 day of her pregnancy for a routine first-trimester ultrasonographic scan.
Our examination found an alive fetus of CRL 48,6 mm, corresponding to 11 weeks + 5 days of pregnancy. Prominent nuchal translucency was the first striking discovery and further particular examination revealed following findings:
- Increased size of the nuchal translucency (NT 5,4 mm);
- Hypoplastic right ventricle of the heart with severe tricuspid regurgitation;
- Pulmonary artery was filled by reversed fashion via the ductus arteriosus.
The findings were indicative of the pulmonary atresia with intact ventricular septum (PAIVS).
The parents opted for the termination of the pregnancy.
