Abstract：Objective: To evaluate the feasibility of using four-chamber view to assess fetal esophagus. Methods: All patients(423 cases) underwent prenatal ultrasound examination to get four-chamber view of esophagus(apical four-chamber view or parasternum four-chamber view or cardiac base four-chamber view). Fetal position and distance between fetal heart and the probe were recorded. Results: Among 423 cases, 95.0%(402/423) cases can display esophagus with the four-chamber view. Among all four-chamber views, parasternum four-chamber view was the best way to display fetal esophagus(P<0.05). Fetal position and the distance between fetal heart and the probe were influence factors. Conclusion: It is feasible to display fetal esophagus with the four-chamber view. Parasternum four-chamber view is the best way to display fetal esophagus among three four-chamber views.
