TAVR accounted for $215 million in Medicare payments in its first year of clinical use. Among SAVR Medicare patients at a similar risk level, TAVR was associated with higher hospital costs despite shorter ICU LOS and hospital LOS. Overall and/or medical device cost reductions are needed for TAVR to have a net neutral financial impact on hospitals.
TEVAR is feasible in chronic dissection but is limited by complex dissection-related anatomy. Increasing number of visceral vessels off the false lumen, maximum preoperative aortic size, and location of the primary tear on the greater curve were associated with poorer remodeling.
For patients ineligible to receive TF TAVR, TAO and TA approaches offer similar clinical outcomes at similar cost with acceptable operative and 1-year survival, except for higher rates of CPB use in TA patients. CPB was associated with worse survival and increased costs.
Elective root replacement operations in patients younger than 70 are associated with low rates of mortality and reoperation, which should be considered the benchmark operation for aortic valve-sparing or repair operations in similar patients. Worse survival was associated with severe AI and older age, suggesting earlier intervention may be an appropriate therapeutic strategy in selected patients.
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.
