Summary:In this manuscript, we describe the potential role of the pericardial space as a drug delivery reservoir to administer angiogenic agents to the heart resulting in functionally significant angiogenesis with single bolus basic fibroblast growth factor (bFGF) delivery. We also describe a percutaneous subxyphoid pericardial access technique that is safe, rapid, and reliable.
A single intrapericardial bolus of basic fibroblast growth factor may be a useful therapeutic strategy for the treatment of myocardial ischemia in patients with coronary artery disease. Although chronic myocardial ischemia is associated with increased expression of inducible nitric oxide synthase, it does not appear to be the cause of altered endothelial function.
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.
