“…The presence of an isolated right SCA arising from the pulmonary artery in association with transposition of great arteries is extremely unusual, with only a few cases reported previously. [11][12][13] The diag- SCA. To the best of our knowledge, there are 10 cases of isolated left CCA described in the literature, all having a right-sided aortic arch and aberrant left SCA.…”

Aim: To evaluate the imaging characteristics and associations in patients with isolation of arch vessels on multidetector computed tomography angiography (CTA). Materials and Methods: We retrospectively reviewed all multidetector CTA studies performed for the evaluation of congenital heart diseases (CHDs) at our institution from January 2014 to June 2020. Cases with isolation of arch vessels were identified. The isolated arch artery and its relationship with patent arterial duct, pulmonary artery, and aortic arch were characterized in addition to other associated intra-and extracardiac anomalies. Results: Isolation of arch vessels was seen in 14/3926 (0.36%) patients. Left subclavian artery (SCA) was the commonest isolated arch vessel, involved in 7/14 (50%) cases. Isolation of right SCA, left brachiocephalic artery, and left common carotid artery was seen in 4 (28.6%), 2 (14.3%), and 1 (7.1%) patient, respectively. The isolated arch vessel was seen associated with right aortic arch in 10/14 (71.4%) cases and was on the opposite side of aortic arch in all 14 (100%) patients. Right-sided nonrestrictive patent arterial duct was seen in 3/14 (21.4%) cases, left-sided nonrestrictive patent arterial duct was seen in 1/14 (7.1%) while a left-sided restrictive patent arterial duct was seen in 3/14 (21.4%) cases. Tetralogy of Fallot (ToF) was the commonest associated anomaly seen in 8/14 (57.1%) patients. Conclusion: Isolation of aortic arch branch vessels is rare, seen most commonly associated with ToF. Left SCA is the commonest involved vessel. CTA is useful not only in the diagnosis of isolation of arch vessels, but also in the presence or absence of associated anomalies which may impact the symptomatology, prognosis, and surgical management.

“…Several cases of this phenomenon have been documented. [14][15][16][17][18] Additionally, Vuran et al reported a case of anomalous RSCA from the main PA in a patient with VSD and coarctation of the aorta. 19 Patients with type B IAA and severe subaortic stenosis often have anomalous origin of the RSCA from the descending aorta; 10 however, associated isolation of the RSCA in this condition is extremely rare.…”

Interrupted aortic arch is a rare congenital heart malformation occurring in approximately three per 1 million births. Type B interrupted aortic arch (interruption between the second carotid artery and the ipsilateral subclavian artery) is the most common of three major types (A, B, and C). We report an extremely rare finding: a case of left-sided type B interrupted aortic arch with isolation of the right subclavian artery (origin from the right pulmonary artery).

“…[1][2][3][4][5][6] Diagnosis is usually made using computed tomography (CT), MRI, or invasive angiography. 1,3,4,6 We report a patient with d-TGA who presents with unusual differential cyanosis, raising concerns of aortic arch anomalies, who was subsequently diagnosed with AORSA using transthoracic echocardiography (TTE). This case demonstrates the importance of considering aortic arch anomalies in d-TGA when patients do not show reverse differential cyanosis.…”

Diagnosis of anomalous origin of the right subclavian artery from the right pulmonary artery in a patient with D‐transposition of the great arteries utilizing transthoracic echocardiography

Diagnosis of anomalous origin of the right subclavian artery (AORSA) from the right pulmonary artery (RPA) is usually made using CT, MRI, or invasive angiography. We report a patient diagnosed using transthoracic echocardiography (TTE). A newborn girl prenatally known to have d-TGA presented with cyanosis sparing the right hemithorax and arm. Oxygen saturations on the right hand were persistently higher than on the right ear and other extremities. Repeat TTE using a modified echocardiographic imaging plane allowed for full visualization of the entire subclavian artery course, revealing AORSA from RPA. We discuss further the approach to echocardiographic diagnosis and surgical implications.
