CSH is associated with a significantly increased risk of infection requiring hospitalization within 1 year following cardiac implantable electronic device surgery. Strategies aimed at reducing hematomas may decrease the long-term risk of infection. (Bridge or Continue Coumadin for Device Surgery Randomized Controlled Trial [BRUISE CONTROL]; NCT00800137).
This meta-analysis shows that durable PVI is associated with a lower risk of AF recurrence after catheter ablation. However, the association was modest, and PV electrical reconnection is common, affecting 58% of AF-free patients. Analysis of studies that included exclusively patients with paroxysmal AF showed a weaker relationship. Additional research is warranted to better understand the mechanism(s) of benefit of catheter ablation for AF and investigate whether PVI should be the primary goal.
Both F-FDG PET-CT and LS yield high sensitivity, specificity, and accuracy, and thus seem to be useful for the diagnosis of CIED infection, based on robust data forF-FDG PET-CT but limited data for LS. When available,F-FDG PET-CT may be preferred.
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.
