PCI complications: factors associated with complications
Editors-In-Chief: Alexandra Almonacid M.D. [1] and Jeffrey J. Popma M.D. [2]
Early Clinical Outcomes After PCI
- Anatomic Success: Residual diameter stenosis < 50 % which is generally associated with at least a 20 percent improvement in diameter stenosis and relief of ischemia.
- Pre-Stent Era: 72 – 74%.
- Stent Era: 82 – 98%
- Procedural Success: Angiographic success without the occurrence of major complications (death, MI, or CABG) within 30 days of the procedure.
- Clinical Success: Procedural success without the need for urgent repeat PCI or surgical revascularization within the first 30 days of the procedure
