Aortic arch procedures have traditionally involved complex surgery with increased risk of mortality and morbidity. Throughout the last decade, however, novel and safe surgical approaches aimed at debranching the great vessels with definitive aortic arch repair have been developed. Currently, hybrid arch procedures allow for open or minimally invasive aortic access to be complemented by endovascular stent-graft techniques, which may eliminate the need for prolonged hypothermic circulatory arrest and its associated complications. Hybrid thoracic aortic and arch repairs have become the preferred approach, with open procedures performed only if hybrid approaches are not possible for technical reasons. In the future, aortic pathology may also benefit from the development of branched and fenestrated endografts that would be deployed in a modular fashion. This article describes the rationale, procedural steps, and recent outcomes data of novel aortic arch procedures.
