Describes the normal embryologic development of the aortic arch Recognizes anatomic variants and anomalies of the aortic arch Identifies common causes of vascular rings
Congenital variants and anomalies of the aortic arch are important to recognize as they may be associated with vascular rings,
congenital heart disease (CHD),
and chromosomal abnormalities,
and can have important implications for prognosis and management,
including surgical and percutaneous interventions. Aortic arch anomalies can occur in isolation but may also be associated with structuralCHD.
other arch variants,
such as right aortic arch with aberrant left subclavian artery,
Findings and procedure details
cardiac magnetic resonanceimaging,
and computed tomographic angiography are important imaging modalities used to identify and diagnose aortic arch variants and anomalies.
These noninvasive imaging modalities have largely replaced catheter angiography and barium esophagrams in the diagnosis of suspected vascular rings. In the pediatric setting in particular,
transthoracic echocardiography is often the initial imaging modality used.
Ultrasonography poses minimal risk...
Congenital anomalies of the aortic arch,
which take many forms,
result from aberrant development of one or more components of the embryonic pharyngeal arch system.
Familiarity with the spectrum and imaging appearance of aortic arch variants,
and malformations is essential for accurate diagnosis and classification and to guide management.
Noninvasive imaging with CT and MR angiography allows for complete evaluation of the aortic arch and branch vessels in relation to surrounding...
