Prenatal diagnosis of truncus arteriosus using multiplanar display in 4D ultrasonography

Prenatal diagnosis of complete atrioventricular septal defect with truncus arteriosus.

Truncus arteriosus (TA) is a rare cardiac anomaly constituting less than 1% of all congenital heart defects. Its association with complete atrioventricular septal defect (AVSD) is extremely unusual and only 12 cases diagnosed postnatally or postmortem have been reported so far. We describe the first case of truncus arteriosus with AVSD to be diagnosed prenatally by fetal echocardiography.

Truncus arteriosus

Diagnosis of truncus arteriosus in first trimester of pregnancy using transvaginal four-dimensional color Doppler ultrasound.

We present our experience of using transvaginal three/four-dimensional (3D/4D) color Doppler with glass-body rendering mode and spatiotemporal image correlation (STIC) software to construct an image of persistent truncus arteriosus in the first trimester of pregnancy. There have been numerous reports on the antenatal diagnosis of truncus arteriosus using two-dimensional (2D) grayscale echocardi...

Truncus Arteriosus

We have encountered difficulty in recognizing and identifying clinically true truncus arteriosus with pulmonary arteries (type 1) because of its resemblance to correctable cardiac defects such as patent ductus arteriosus, aortic-pulmonic defect, and ventricular septal defect. In the present report we are presenting clinical information on 14 patients with this anomaly, both to supplement the sc...

Prenatal diagnosis of hypophosphatasia congenita using ultrasonography

Congenital hypophosphatasia is a rare fatal skeletal dysplasia. Antenatal determinants of Epub ahead of print lethality include small thoracic circumference with pulmonary hypoplasia and severe micromelia. These features were present in the fetus of a 25-year-old female who came for an anomaly scan in her second trimester of pregnancy. Additional findings of generalized demineralization and ost...
