Abstract:
Purpose To explore the ultrasound features and early diagnostic clues of fetal myocardial non-compaction.Materials and Methods The clinical data and echocardiographic data of four fetuses who underwent fetal echocardiography in Henan Provincial People's Hospital from January 2015 to February 2023 and were confirmed to have myocardial non-compaction by pathological finding or postnatal examination were collected,and analyzed.Results A total of four fetuses diagnosed as myocardial non-compaction by prenatal ultrasound:two involved the left ventricle with isolated lesions,and apical myocardial non-compaction was confirmed by postnatal echocardiography;two involved the biventricles,and both of which were pathologically confirmed after induction of labor.The prenatal ultrasound of fetal myocardial involvement in four cases showed that:(1)the affected myocardium showed a bilayer structure:the outer layer was compacted myocardium,which showed thin and compacted homogeneous hypoechoic;the inner layer was loose and thickened non-compacted myocardium with enhanced echogenicity;(2)color Doppler flow imaging:the non-compacted myocardium showed sieve mesh blood flow with ventricular communication.Some cases were associated with cardiac enlargement and arrhythmia.Conclusion Prenatal echocardiography can diagnose fetal myocardial non-compaction with a characteristic echographic presentation.Localized myocardial thickening and echogenic enhancement,cardiac enlargement and arrhythmia may be important clues to identify fetal myocardial non-compaction.
