Clinical value of prenatal echocardiographic examination in the diagnosis of fetal cardiac tumors.

ABSTRACT

The aim of the present study was to explore the clinical value of prenatal echocardiographic examination in the diagnosis of fetal cardiac tumors. In total, the cases of 8 fetuses with fetal cardiac tumors, which were identified by prenatal ultrasound examination in The First Affiliated Hospital of Nanchang University between January 2012 and January 2014, were retrospectively analyzed. The size, shape, location, activity and hemodynamic changes of the lesions were described in detail, and the patients were followed up. Out of the 8 identified cases of fetal cardiac tumors, 2 fetuses contained tumors only in the left ventricular cavity and 6 fetuses contained tumors of the left and right ventricular cavities, interventricular septum and apex of the heart. Overall, 5 of the 8 female patients requested termination of the pregnancy and labor was induced. The fetuses were pathologically confirmed to possess rhabdomyoma. In addition, 1 patient was followed-up for 5 weeks, and the tumor in the fetal heart cavity was found to have enlarged and developed in multiple regions when follow-up was performed. The patient then requested termination of the pregnancy and labor was induced. The fetus was pathologically confirmed to possess rhabdomyoma. The remaining 2 patients insisted on continuation of the pregnancy and the fetuses were followed up during gestation and subsequent to birth by echocardiographic examination. Prenatal echocardiography may precisely position and diagnose occupying lesions of the fetal heart, which is of considerable value in clinical decision making and instruction for treatment.
