Abstract Prenatal ultrasound examination is used for screening congenital heart defects and fetal genetic diseases. Unfavorable factors such as low signal-to-noise ratio, artifact and poor fetal posture in ultrasound images make it a very complicated task to identify and interpret the standard scan plane of the fetal heart in prenatal ultrasound examinations. Deep learning related methods are widely used to process and analyze medical images. However, designing an effective network structure for a specific task is a time-consuming and relies on expert knowledge. In order to obtain an effective fetal ultrasound image classification model in a short time, this paper collects and organizes the Fetal Heart Standard Plane(FHSP) level III screening dataset, and we use the Differentiable Architecture Search(DARTS) method for FHSP classification task to automatically obtain an efficient adaptive classification deep model called Ultrasound Image Adaptive Classification model(UIAC) for assisting the diagnosis of fetal congenital heart disease. This new model is a deep neural network consisting of two automatically searched optimal blocks. Our UIAC model has fewer parameters than the mainstream manned classification networks. Moreover, it has achieved the best recognition results on the FHSP classification task: top1-accuracy 89.84%, macro-f1 89.72%, kappa score 88.82%.

Cardiac Diagnosis

Prenatal ultrasound screening has allowed for the detection of in utero cardiac abnormalities. Specifically, distinction is possible between ventricular diverticula and aneurysms, which is important because each condition has a different clinical outcome. We report the case of a 35-year-old, gravida 1, para 1 woman, with no significant past medical history, who underwent routine prenatal ultrasound screening at 32 weeks’ gestation. A four-chamber ultrasound of the fetal heart combined with M-mode echocardiography showed abnormal dilatation of the right ventricular chamber measuring 2.2 cm × 1.0 cm but with normal contractility. Delivery was performed at full term by cesarean section, and a right ventricular diverticulum was confirmed by postnatal cardiac computed tomography. The baby developed normally with no cardiac sequelae during followup. This case demonstrates the importance of making a correct diagnosis of ventricular diverticula by prenatal ultrasound when abnormal dilatation of the fetal ventricle is identified during routine screening. Because evaluating the wall contractility by M-mode ultrasound leads to evaluating whether it has the myocardium, we conclude that M-mode echocardiography is effective for the purpose of prenatal cardiac diagnosis and can distinguish between ventricular aneurysms and functioning ventricular diverticula.

Seven cases of prenatal ultrasound diagnosis of idiopathic infantile arterial calcification in early gestation are presented. During ultrasound examination of the fetal heart in all cases was determined echogenic interventricular septum. Almost all cases have pregnancy terminated because of unfavourable prognosis. On only one occasion the baby died after 5 days after birth. The literature data on early prenatal ultrasound diagnosis of idiopathic infantile arterial calcification and features of detection this pathology were analysed.

The physiology of the fetal heart differs significantly from that of the mature post-natal organ: e.g., the metabolic supply for adult cardiac contraction relies mainly on fatty acids; whereas, the fetal heart uses carbohydrates as its primary energy source. Limited morphological descriptions of the developing myocardium have appeared. However, additional studies are required to elucidate the ultrastructural changes occuring in the perinatal period when enormous physiological adjustments are made. Although adult animals are most often used in toxocological and pathological analyses, it is also important to investigate fetal cardiac responsiveness to various agents. The vulnerability of the ultrastructure of the fetal mouse myocardium to genetic and environmental assault is the subject of this report. The genetically determined effect on the heart was observed in mouse embryos homozygous for the cab (cardiac abnormality) mutation discovered by Essien.
