Prenatal screening and diagnosis of fetal anomalies rely upon ultrasound studies (US). US is generally considered safe during pregnancy. It is estimated that 1% of all neonates are born with a congenital heart defect that makes careful standardized examination of the fetal heart a mandatory step during all fetal US exams. US examination of the fetal heart requires at least analysis of the fetal situs, the four-chamber (4CH) view and the three-vessel view (3V). In the evaluation of the fetal heart, it is now worldwide accepted that the three-vessel trachea (3VT) view should be obtained, if technically feasible, in supplement of the other classical fetal cardiac views (4CH, 3V).

The relevance of adding the 3VT view is that some congenital cardiovascular abnormalities, potentially significant for fetal outcome, can only be diagnosed with this view; these malformations include vascular rings and right aortic arches. Read More
