OP01.07: Intrauterine evolution of fetal cardiac defects diagnosed between 11 and 14 weeks of gestation

Abstract

Objectives: To investigate the value of two-dimensional combined with STIC technique to localize the VSD in fetus. Methods: From June 2010 to October 2010, 378 pregnant women were included in our study. GE Voluson E8 was used. The definition of the types of VSD: perimembrane type, isolated membrane type, subseptal valve type, subcrista type, intracrist type, and muscular type. The subseptal valve type and the inlet muscular type were confirmed in four-chamber view. Membrane type, perimembrane type, outlet muscular type were confirmed in left ventricle outlet view. Results: 27 ventricular septal defects were diagnosed by two dimensional echocardiography combined with STIC. The typy and located ventricular septal defect compared with autopsy and echocardiography after birth. The coincidence 92.5%. Conclusions: The type of ventricular septal defect can be diagnosed by two dimensional and STIC echocardiography.
