Screening for fetal CHD is most effective when you assess multiple complementary planes to get a complete picture of heart anatomy and great vessel relationships. The four-chamber view confirms the basic layout of the atria and ventricles, as well as atrioventricular connections and chamber sizes, providing an essential first checkpoint. Adding the left and right ventricular outflow tract views checks how the ventricles connect to the great arteries and reveals outflow tract or concordance issues that the four-chamber view can miss. The three-vessel-trachea view then integrates the relationship and sizes of the great vessels in the upper mediastinum, helping identify disproportion, abnormal arch configurations, or other alignment problems that signal more complex CHD. Using all three types together gives a systematic, thorough assessment and reduces the chance of missing lesions, whereas relying on only one or two views can leave certain defects undetected.
