A case of fetal isolated ventricular noncompaction with TNNT2 gene mutation and literature review

Abstract

Background Ventricular noncompaction (VNC) is a cardiomyopathy characterized by overdeveloped ventricular trabeculaes and deep recess, which has been rarely reported. Case presentation A 29‐year‐old Chinese pregnant woman with no obvious fetal abnormality in regular prenatal examination during first and second trimester. However, at 32 weeks of gestation, both obstetric growth scan and fetal echocardiogram revealed an enlarged heart with grid‐like changes at the apical region. Eventually, the genetic and autopsy findings indicated the deceased infant with VNC. Conclusion Isolated VNC could be detected prenatally, even during the late pregnancy. Fetuses suspected of VNC should be offered genetic tests.
