“…Left-sided AA was found in 55 patients (71.6%) and right-sided AA was found in 22 patients (28.3%). Despite this incidence being cope with many review articles as Lapierre et al [3] and Zakaria et al [14] in which RAA incidence about 25 and 30% respectively, this incidence is more or less in accordance with other authors as Hu et al [10] and Tawfik et al [30]. They reported incidence of RAA in TOF patients as 18.5 and 37% respectively.…”

“…Despite AA variants are often asymptomatic and reported as an incidental finding, recently they have been found to pose a greater risk of hemorrhage and ischemia during surgery in the thorax [29]. Variations in the AA type and branching pattern are important to recognize before cardiothoracic surgeries or interventional procedures because they could affect the technique of some of them [30]. In our study, we have found many AA variants in TOF patients.…”

Background Tetralogy of Fallot is the most common congenital cyanotic heart disease. Advances in surgical repair recently facilitate survival of the affected patients into adulthood with good quality of life. Despite imaging plays crucial role in diagnosis of TOF patients, no single diagnostic modality suffices for complete evaluation of TOF. Thus, different diagnostic tools should be used alone or in combination according to patient’s clinical question. This study aims to find out the agreement between the echocardiography and MDCT in evaluation of TOF patients prior to surgical repair. Results Three-step approach used in scanning TOF patients. Firstly, classic TOF findings, MDCT was comparable to echocardiography in overriding aorta (k = 0.6), VSD (k = 0.8), RVH (k = 0.4), and sub valvular pulmonary stenosis (k = 0.6). Echocardiography is superior to MDCT in evaluation of valvular stenosis (k = 0.4). MDCT was superior to echocardiography in supravalvular pulmonary stenosis. Secondary, surgical relevant findings, McGoon ratio calculated in 94.2%, small and major APCs in 45.5% and 28.5% respectively, PDA in 35% and anomalous coronary artery in 5.1%. Thirdly, other TOF-associated anomalies, common: ASD (34.3%) and RAA (28.3%), and persistent LSVC (10.3%). Uncommon: situs ambiguous (2.5 %), PAPVR (1.2%), and IVC anomalies (3.8%). MDCT was superior to echocardiography in surgical relevant findings and other TOF-associated anomalies. Conclusion MDCT is a crucial imaging tool for extra cardiac evaluation of TOF patients prior to surgical repair.

“…RAMI is strongly associated with CHD in greater than 98% of cases, especially tetralogy of Fallot and truncus arteriosus [12]. According to Tawfik et al, 18% of children with CHD present a RAA [13]. Evans et al hypothesized that a right aortic arch in situs solitus, with or without an associated cardiovascular malformation, is often associated with a vascular ring [14].…”

Right aortic arch with mirror image branching (RAMI) is a rare congenital defect of the aorta. The exact incidence of RAMI in the general population is unclear. In RAMI the first branch arising from the arch is the left innominate artery, followed by the right carotid artery and right subclavian arteries. We report a case of an adult female patient with RAMI discovered as an incidental finding during radiological investigations for suspected pulmonary embolism in emergency department. No other congenital malformations were reported. It is important to recognize congenital variants of the aortic arch, as they can have relevant implications for patients’ prognosis and management. Therefore, being aware of these conditions is key to avoid any mistakes or surgical and endovascular complications.

“…Some authors suggest a correlation between variations in the aortic arch and other pathologies such as intracranial aneurysms [22] and plates of atheroma at the level of its origin [28]. Patients with congenital heart disease have been linked to higher variability, presenting the normal 3-branch-pattern in only half (50.5%) of the cases [24].…”
