Therapeutic myocardial angiogenesis using percutaneous intrapericardial drug delivery

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.
