Fetal cardiac diverticulum: a case report / 中华围产医学杂志

ABSTRACT

We report a case of fetal cardiac diverticulum diagnosed by ultrasound in the second trimester in a patient who finally had an induced abortion. The 28-year-old pregnant woman went to the Department of Obstetrics of Henan Provincial People's Hospital due to a fetal cardiac abnormality found by ultrasound in a local hospital at 25 +3 gestational weeks. At 25 +4 gestational weeks, fetal echocardiography showed a suspected fetal pericardial cyst, and further MRI showed a left ventricular structure disorder. Fetal echocardiography performed at 25 +5 weeks of gestation identified a cystic echo in the pericardial cavity in the fetus's left-ventricular side, communicating with the left ventricle. A weakened pulsation of the left ventricle and fetal edema were also found. Intraamniotic injection of ethacridine was performed for induced abortion due to suspected fetal cardiac diverticulum at 26 weeks of gestation, and fetal left ventricular diverticulum was diagnosed by pathological examination. Copy number variation analysis showed a 744 kb duplication in p15.3p15.2 region of chromosome 11 with unidentified pathogenicity.
