Aortic arch view (fetal echocardiogram)

Last revised by Dr Yuranga Weerakkody on 29 Jan 2019

An aortic arch view is one of the additional views performed on fetal obstetric ultrasound - fetal echocardiography. It is an oblique sagittal view which is obtained similar to a left anterior oblique angiogram or the sagittal arch view obtained in CT arteriography. The isthmus, after the origin of the left subclavian artery, is the narrowest part of the aortic arch.
