Imaginea de 3 vase ca metodă de screening a malformaţiilor conotruncale

Prenatal detection of fetal anomalies allows the adequate counseling of the parents regarding the pregnancy and the neonatal prognosis. This is especially true in the case of congenital heart defects where counseling the parents is essential, given the high neonatal mortality of such anomalies. Conotruncal malformations are made up of a wide variety of congenital heart defects with abnormal ventriculoarterial connections and represent up to 30% of all cases of congenital heart defects. The most common types of conotruncal malformations are tetralogy of Fallot, transposition of great arteries, double outlet right ventricle, common arterial trunk, but numerous anatomical variants exist. The 3-vessel view can be used as an alternative to the ventricular outflow tract views to detect conotruncal malformations and may be used as a screening test. To test this hypothesis, we evaluated the 3-vessel view in both normal cases and cases of conotruncal malformations. As expected, in the 30 normal cases we reviewed, all the criteria for a normal 3-vessel view were met. In the 15 cases of conotruncal malformations (tetralogy of Fallot, transposition of great arteries, double outlet right ventricle, common arterial trunk) that we investigated, at least one criterion for a normal 3-vessel view was not met. This goes to show the utility the 3-vessel view can have in the screening for conotruncal malformations
