Supravalvular aortic stenosis

Case report

This is a case of a healthy G2 P0 who was scanned at our department at 18 weeks of gestation. Her first trimester ultrasound screening was negative. She had non-contributive family or personal history.
The ultrasound exam detected the following findings:

- Marked dilation of the left ventricle without signs of contractility
- Narrow aorta on the three vessel view
- Reversed flow via ductus arteriosus

Our diagnosis based on the ultrasound exam was a severe aortic stenosis.

The follow-up ultrasound in 2 weeks showed that left ventricle was of the same size as the right ventricle but with signs of endocardial fibroelastosis.

The patient decided for pregnancy termination. The pathological report confirmed our findings, the final diagnosis was a supravalvular aortic stenosis.
 

Images 1,2: 18 weeks, 3-vessel view, images show the ductus arteriosus (blue) and aorta (red) with a reverse flow from the ductus arteriosus.

 

Images 3,4: Images of the stenotic aorta and ductus arteriosus.

 

Images 5,6: Image 5 shows a 3-vessel view with pulmonary, aorta and superior vena cava. Image 6 shows a descending aorta.

  

Video 1,2: 18 weeks, Video 1 shows a 4-chamber view with markedly dilated left ventricle. Video 2 shows a 3-vessel view with a retrograde flow of the blood in the aorta (red).

 

Video 3,4: 4-chamber view with a dilated left ventricle without contractility. Video 4 shows a longitudinal view of the aortic arch.

 

Video 5: 21 weeks, 4-chamber view, left ventricle shows the signs of endocardial fibroelastosis and does not contract.
