Abstract:Surgery for aortic dissections or aneurysms can be extended into the aortic arch by hemiarch replacement (HAR) or total arch replacement (TAR). Although cardiovascular surgeons have been performing HAR and TAR for decades, the mechanical properties of HAR and TAR are not well understood. This study investigates the mechanical behaviors and stress distributions in HAR and TAR using a hybrid fluid-structure interaction analysis that combines computational fluid dynamics and structural static analysis.

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.
