Recent Development in Three and Four Dimension Fetal Echocardiography.

Since its introduction >15 years ago, the use of spatial and temporal image correlation (STIC) technology has contributed substantially to fetal echocardiography. Moreover, significant advances have occurred in 3- and 4-dimensional (3D/4D) echocardiography over the past several years including the matrix probe along with advances in gray scale and color Doppler post processing, resulting in improved display of ultrasound images. In this article, we provide examples to show these recent developments including the use of color Doppler with STIC in the glass-body mode and the matrix probe thus enabling the demonstration of cardiac anomalies of the 4-chamber-view and great arteries.

Fluid area measurements in the posterior fossa at 11-13 weeks in normal fetuses and fetuses with open spina bifida.

Objectives: To measure the area of the intracranial translucency (IT) (syn: 4th ventricle) and the future cisterna magna (CM) in normal fetuses and to compare with fetuses with open spina bifida.

Patients: In the midsagittal plane of the face of 220 fetuses between 11 and 13 weeks' gestation, the areas of the IT and CM were measured and the sum, defined as the posterior fossa fluid (PFF) area was calculated. Reference ranges were constructed in relation to the crown-rump length.

Rhabdomyomatous dysplasia of the newborn lung associated with multiple congenital malformations of the heart and great vessels.

Interstitial proliferation of striated muscle in the lung is extremely rare. Most cases are associated with other congenital malformations, such as lung sequestration, diaphragmatic hernia, or cardiac malformations. We describe a newborn with rhabdomyomatous dysplasia of the lung associated with multiple congenital malformations of the heart and great vessels.
