Despite the fact that the variations in question are usually asymptomatic, they may cause dyspnea, dysphagia, intermittent claudication, misinterpretation of radiological examinations and complications during neck and thorax surgery. Furthermore, these variations may be accompanied by other congenital abnormalities.
The ARSA has a relative high incidence in Greeks and a female predominance. The aberrant vessel follows a retroesophageal course in most cases and only one case with a location between trachea and esophagus was detected. The retroesophageal ARSA justifies the wide variety of clinical manifestations and complications occurred.
Vascular calcification is a highly prevalent pathophenotype that is associated with aging, atherosclerotic cardiovascular disease, diabetes mellitus, and chronic kidney disease. When present, it portends a worse clinical outcome and predicts major adverse cardiovascular events. Heavily calcified coronary and peripheral artery lesions are difficult to dilate appropriately with conventional balloons during percutaneous intervention, and the use of several adjunctive strategies of plaque modification has been suggested. Intravascular lithotripsy (IVL) offers a novel option for lesion preparation of severely calcified plaques in coronary and peripheral vessels. It is unique among all technologies in its ability to modify calcium circumferentially and transmurally, thus modifying transmural conduit compliance. In this article, we summarize the currently available evidence on this technology, and we highlight its best clinical application through appropriate patient and lesion selection, with the main objective of optimizing stent delivery and implantation, and subsequent improved short- and long-term outcomes. We believe that the IVL balloon will transform the market, as it is easy to use, with predictable results. However, cost-effectiveness of such advanced technology will need to be considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
