We have confined that more than half of the fetuses with DS bear a CHD, which is an AVSD in 44% of cases. Conversely, 43% of fetuses with an AVSD have trisomy 21. For VSDS, the situation is controversial, due to the relatively low detection level of this heart defect at the routine mid-trimester obstetric scan.

DaTscan had a significant impact on clinical management, diagnosis and CoD in patients with CUPS. DaTscan is safe and well tolerated, and is a useful adjunct to differentiate a diagnosis of CUPS. Trial registration number http://ClinicalTrials.gov Identifier: NCT00382967.

This study demonstrated that 2D-S is a feasible and reproducible approach to assess regional ventricular function in the foetal heart, ready for the clinical application.

TDI evaluation of the fetal heart is feasible and reproducible. Color-TDI is able to identify the various phases of the cardiac cycle. Quantitative evaluation of myocardial velocities has shown also in the fetus the existence of the myocardial velocity gradient found in postnatal life.
