A 30-year-old woman (G2P1), with non-contributive history, was referred to our antenatal unit at 23 weeks of gestation due to fetal cardiopathy. Our ultrasound examination demonstrated following cardiac anomalies:

• Dilated left ventricle at the level of the four-chamber view of the heart;
• Hyperechoic and hypoechoic walls of the left ventricle (fibroelastosis);
• Aortic valve stenosis;
• Dysplastic mitral valve;
• Normal pulmonary artery.

Amniocentesis was performed with normal result. The parents opted to terminate the pregnancy.

Images 1, 2: 23 weeks of gestation; the images show dilated left ventricle of the heart with hyperechoic rim of fibroelastosis.

 

Images 3, 4: 23 weeks of gestation; the images show left outflow tract of the heart with stenotic part of the aorta at the level of semilunar valves.

 

Images 5, 6: 23 weeks of gestation; the images compare the size of the aortic outflow (left part of the images) with the size of the pulmonary artery (right part of the images). The aorta is stenotic at the level of the semilunar valves.

 

Videos 1, 2: 23 weeks of gestation; the videos show left outflow tract of the heart with stenotic part of the aorta at the level of semilunar valves.
 
 

Videos 3, 4, and 5: 23 weeks of gestation; the videos dysplastic mitral valve with decreased flow across the valve (videos 4, 5).
