Abstract

The aim of the study was to evaluate the feasibility of obtaining the three-vessel and trachea view (3VTV) in an unselected population undergoing first trimester screening for aneuploidy, and to investigate its role in the early detection of congenital heart defects (CHD). Cardiac examination was performed by expert sonographers. Abnormal findings of 3VTV were classified in three different subgroups: number, size and spatial relationship of the vessels. We enrolled 6350 consecutive singleton pregnancies and included 5343 cases. Examination of 3VTV was feasible in 94% of cases. Fifty-seven (1%) CHD were present in the study period; 24 cases were excluded because parents opted for termination of pregnancy. Of the remaining 33 cases, 25 were suspected at the first trimester and eight were detected only at the mid-trimester. An abnormal 3VTV was suspected in 22 cases, and it was confirmed in 21. Five cases that were erroneously classified in the subgroup of abnormal vessel number were actually characterized by a diminutive size of one of the great arteries. The detection rate for CHD, including 4-CV and 3VTV, was 75.8%. Our study demonstrates that 3VTV is an easy plane to obtain by expert sonographers in an unselected population du...Continue Reading
