Utility of a Single 3‐Vessel View in the Evaluation of the Ventricular Outflow Tracts

Abstract

A single 3-vessel view image can serve as a representative view of the outflow tracts and can show ventricular outflow tract anomalies with high sensitivity. Given that the conventional outflow tract views can be difficult to obtain, the 3-vessel view may serve as an effective first-line view when evaluating the ventricular outflow tracts for congenital heart disease.

The added value of screening fetal echocardiography after normal cardiac views on a detailed ultrasound

“…With the addition of the outflow tracts to the standard 4‐CH view, CHD detection improved from at best 63% to upwards of 90% . The 3VV has 91% sensitivity in detecting ventricular outflow tract defects . Thus, the addition of this view further increased the CHD detection rate.…”

Contribution of the Fetal Cardiac Axis and V‐Sign Angle in First‐Trimester Screening for Major Cardiac Defects

“…Recently published data show that, via color and/or directional power Doppler modes, the 3-vessel and trachea view played a critical role in the first-trimester scan. 22 According to a study by Wiechec et al, 11 45.71% and 71.43% of major CHD can be detected by the 4-chamber view and 3-vessel and trachea view separately, which yielded 88.57% with the combined approach. However, the limitation of their study is that the feasibility might not be duplicated with less experienced technicians because of the possible bias in the image interpretation.…”

“…Although the 3‐vessel and trachea view has a high detection rate in identifying CHD in the second trimester, the image of the 3‐vessel and trachea view cannot be obtained easily only with the 2‐dimensional mode in the first trimester. Recently published data show that, via color and/or directional power Doppler modes, the 3‐vessel and trachea view played a critical role in the first‐trimester scan . According to a study by Wiechec et al, 45.71% and 71.43% of major CHD can be detected by the 4‐chamber view and 3‐vessel and trachea view separately, which yielded 88.57% with the combined approach.…”

Utility of the 3‐Vessel and 3‐Vessel and Trachea Views in Prenatal Diagnosis of a Pulmonary Artery Sling

“…As we know, the 3‐vessel and 3‐vessel and trachea views play a vital role in the evaluation of great vascular anomalies. The relationship of the PA, aorta, ductus arteriosus, superior vena cava, and trachea in the upper mediastinum can be observed via the 3‐vessel and 3‐vessel and trachea views, which is of crucial importance in the identification of a PA sling . In normal conditions, the PAs are located anterior to the primary bronchi and form an inverted Y shape in the 3‐vessel view, whereas the aorta and ductus arteriosus are located on the left side of the trachea and form a V shape in the 3‐vessel and trachea view (Figure ).…”
