No difference in 30-day NACE rate was observed between ASA-only or DAPT following TAVI. Moreover, a trend towards less life-threatening and major bleeding was observed in favour of ASA. Consequently the additive value of clopidogrel warrants further investigation.
This small series demonstrates the feasibility of paravalvular leak closure with the CoreValve TAVI, despite the adverse aortic lattice. The AVP4 device is ideally suited to this situation as it will pass through a 0.038' lumen and can therefore be delivered down standard diagnostic catheters.
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.
