Transoesophageal echocardiography can visualise and evaluate aberrant right subclavian artery stenosis and post-stenting status

In heavily calcified vessels, computed tomography is limited in its ability to accurately assess stenosis severity because of artefacts caused by calcification, and it cannot characterise plaque morphology. In addition, post-stenting lumen evaluation is often hindered by metal artefacts. In contrast, transoesophageal echocardiography offers real-time imaging, detailed visualisation of plaque characteristics, and reliable confirmation of stent expansion, providing a useful alternative for evaluating and managing aberrant right subclavian artery stenosis. <b>Conclusion</b>: Transoesophageal echocardiography enables precise pre-procedural assessment and post-stenting evaluation.
