Figure 1. Fetal echocardiography at 25+1weeks of gestation. (A) The two-dimensional ultrasound image shows increased numbers of prominent trabeculations and deep intertrabecular spaces in both ventricles (yellow arrow), especially at the left ventricular apex, with a noncompaction:compaction ratio of 3:1. (B) The color Doppler ultrasound image shows blood perfusing the intertrabecular recesses (white arrow). LA, left atrium; LV, left ventricle; RA, right atrium; RV, right ventricle.
