{"title":"The Management of the Aortic Arch in Type A Aortic Dissection: Replace, Repair with the AMDS, or Leave for Another Day?","authors":"Ryaan El-Andari, Michael C Moon","doi":"10.3390/jcdd12010023","DOIUrl":"10.3390/jcdd12010023","url":null,"abstract":"<p><strong>Objectives: </strong>Acute type A aortic dissection (ATAAD) is a life-threatening condition that requires emergent surgical intervention. Numerous surgical approaches exist for ATAAD, and controversy remains regarding the optimal arch interventions for ATAAD patients. Aortic Arch Interventions: Approaches to ATAAD repair include hemiarch repair or extended arch repairs, including the hemiarch with a hybrid stent implantation, such as the AMDS hybrid Prosthesis, total arch replacement (TAR), and the use of an elephant trunk and frozen elephant trunk. While indications for each procedure exist, such as entry tears in the arch, arch aneurysms, and head vessel communications for TAR and malperfusion and a reduced risk of distal anastomotic new entry tears in Debakey I aortic dissection for the AMDS and frozen elephant trunks, the optimal intervention depends on numerous factors. Surgeon and center experience, resource availability, patient risk, and anatomy all contribute to the decision-making process. TAR has improved in safety over the years and has been demonstrated to be comparable to the hemiarch repair in terms of safety in many settings. TAR may also prevent adverse remodeling and can effectively treat more distal diseases, the presence of arch tears, arch aneurysms, and branch vessel involvement or malperfusion.</p><p><strong>Conclusions: </strong>Numerous surgical approaches exist to manage ATAAD, allowing for the surgeon to tailor the repair to the individual patient and pathology. TAR allows for single or staged repair of extensive pathologies and can address distal entry tears, the aneurysmal arch, and head vessel pathologies. In cases with malperfusion, an AMDS can be used in many cases. The management strategy for ATAAD should always involve performing the best surgery for the patient, although in cases where a total arch is indicated but cannot be performed safely by a non-aortic surgeon, the safest approach may be to perform a hemiarch initially and to plan for an elective arch reoperation in the case it is required following close surveillance.</p>","PeriodicalId":15197,"journal":{"name":"Journal of Cardiovascular Development and Disease","volume":"12 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11765524/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143032944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite established guidelines, ED management of AF often varies, revealing important gaps in care. This review addresses specific challenges in AF management for patients in the ED, including the nuances of rate versus rhythm control, the timing of anticoagulation initiation, and patient disposition. The updated 2024 European Society of Cardiology (ESC) guidelines advocate early rhythm control for select patients while recommending rate control for others; however, uncertainties persist, particularly regarding these strategies' long-term impact on outcomes. Stroke prevention through timely anticoagulation remains crucial, though the ideal timing, especially for new-onset AF, needs further research. Additionally, ED discharge protocols and follow-up care for AF patients are often inconsistent, leaving many without proper long-term management. Integration of emerging therapies, including direct oral anticoagulants and advanced antiarrhythmic drugs, shows potential but remains uneven across EDs. Innovative multidisciplinary models, such as \"AF Heart Teams\" and observation units, could enhance care but face practical challenges in implementation. This review underscores the need for targeted research to refine AF management, optimize discharge protocols, and incorporate novel therapies effectively.
