Evaluating the efficacy of sequential cross-sectional scanning and combined teaching methods for prenatal screening of fetal conotruncal anomalies

This study demonstrates that combining fetal heart sequential cross-sectional scanning with a variety of teaching methods, including drawing methods, mind mapping, and CBL, can enhance understanding of fetal trunk structure scanning and foster the development of clinical reasoning skills, ultimately leading to improved diagnostic accuracy in the identification and differential diagnosis of conotruncal anomalies.
