Case report

A 39-year-old woman (G31P2) was seen in our office at 20 and 30 weeks of her pregnancy. She had undergone amniocentesis with positive result for trisomy 18, but parents opted for continuation of the pregnancy. The baby had lumbosacral meningomyelocele with consequent Arnold-Chiary malformation type II, overlapping fingers, intrauterine growth restriction, and following cardiac anomaly:

Case report

A 39-year-old woman (G31P2) was seen in our office at 20 and 30 weeks of her pregnancy. She had undergone amniocentesis with positive result for trisomy 18, but parents opted for continuation of the pregnancy. The baby had lumbosacral meningomyelocele with consequent Arnold-Chiary malformation type II, overlapping fingers, intrauterine growth restriction, and following cardiac anomaly: common arterial trunk (truncus arteriosus communis) - Collett-Edwards type IV.

Images 1, 2, and 3: The images 1 and 2 show color Doppler four-chamber view of the heart with striking left axis deviation, ventricular septal defect. Left and right pulmonary arteries are arising from the descending aorta (descending part of the common arterial truncus) - truncus arteriosus communis Collett-Edwards type IV. Image 3 represents drawing showing the scheme of the anomaly (truncus arteriosus communis Collett-Edwards type IV).

LV - left ventricle; RV - right ventricle, RA - right atrium; LA - left atrium; VSD - ventricular septal defect; LPA - left pulmonary artery; RPA - right pulmonary artery; CAT - common arterial trunk.

Videos 1, 2, and images 4, 5: the videos and images show 4D (video 1), 2D (video 2) and 3D (images 4, 5) imaging showing common arterial trunk (Collett-Edwards type IV).

LV - left ventricle; RV - right ventricle; LPA - left pulmonary artery; RPA - right pulmonary artery; CAT - common arterial trunk.

Images 6, 7 and video 3: sagittal color Doppler imaging of the common arterial trunk (Collett-Edwards type IV).

LPA - left pulmonary artery; RPA - right pulmonary artery; CAT - common arterial trunk.
