stent optimization
Process of ensuring optimal stent expansion, apposition, and positioning using imaging guidance.
Full Definition
Stent optimization refers to the systematic approach of achieving optimal stent deployment through proper expansion, wall apposition, and positioning. This process typically involves intravascular imaging guidance using IVUS or OCT to assess stent dimensions, detect malapposition, edge dissections, or geographic miss. Optimization may require additional balloon inflations, sizing adjustments, or treatment of stent edges. The goal is to achieve complete stent expansion to the reference vessel diameter, ensure proper wall contact, and minimize acute and long-term complications such as stent thrombosis or restenosis.
Usage
Usage note: Emphasize the imaging-guided aspect when applicable.
