Background
When bivalirudin (BIV) is used as an intraprocedural anticoagulant for PCI in lieu of heparin (HEP), the risk of post-PCI bleeding appears to be smaller. This benefit may be a result of its shorter half life. Unlike HEP, its effects cannot be reversed, a potential problem when coronary perforation (PERF) occurs. This study was undertaken to assess that possibility.
