This is a fetal echocardiography presentation that covers proper imaging of the fetal 3-vessel-tracheal view (3VTV) and the imaging techniques used to diagnose arch abnormalities including abnormal branching patterns.
Hello. I had a fetal echo at 24 weeks. Cardiologist mention baby girl having raa. But never mention any genetic testing. She said she would have a normal live. Just if she had any issues swallowing. I just received my results her summary was this. Arch sidedness difficult to visualize but likely left-sided aortic arch. Plan to re-assess on follow-up study. I’m going back in 4 weeks. My nipt test did not detect digeorge syndrome.
Hello, awesome presentation! I needed one clarification- about the 3vt mirror image- so the mirror image is normal too? Or is it abnormal as it is on the right of trachea? Please clarify. Thank you
A right aortic and ductal arch in combination is considered normal when there is mirror image dextrocardia. However, if there is right aortic arch with a right ductus in levocardia, then it is abnormal, but not a vascular ring.
Hi Joe, I’m a trainee sonographer towards the end of my training! I found your presentation is very thorough and informative! Thank you for the excellent presentation! To remember the normal 3VT, I created an easy way last night. 🫰🏻making a heart ❤️ with left hand straight wrist. Then the thumb will be the pulmonary a (DA) and the index finger will be the Ao. Then naturally from left to right, 🫰🏻it has the thumb then index, equals DA then Ao. From anterior to posterior( top to bottom), 🫰🏻naturally has pulmonary then Ao. Thumb(Pulmonary) is naturally slightly bigger than the index (Ao). To make a heart, needs the thumb and index touching, which is the top of ‘V’ sign. ❤️also needs the same color, otherwise that’s Pepsi. Do you think it’s a good way to remember it? Again thank you for your wonderful presentation! 🧡🧡🧡
Hi, I have my 20 week scan anomaly and right aortic arch is present and in 3vt view there is U configuration around trachea suggestive of right aortic arch with left ductal arch. Doctor asked us to ameniocentesis. Is it abnormal condition?with my mental status not really sure what to ask here
Not really associated with aneuploidy or genetic abnormality. There is a slight and rare association with DiGeorge syndrome however. I personally would not recommend amniocentesis.
@@bhavanareddy7333 It is a vascular ring and may need surgery to correct if baby has symptoms. These symptoms include dysphagia (difficulty swallowing) and/or stridor (noisy breathing due to airway compression).
