Step‐by‐step StentBoost‐guided small vessel stenting using the self‐expandable sparrow stent‐in‐wire

A 56 year‐old woman underwent percutaneous coronary intervention for a lesion in a small mid‐left anterior descending coronary artery (reference vessel diameter by quantitative coronary angiography: 2.11 mm) with a novel drug‐eluting stent specifically designed for small vessels, the CardioMind Sparrow stent delivery system. This is a self‐expandable sirolimus‐eluting nitinol stent directly mounted into a 0.014‐inch coronary guidewire. The stent has a very thin strut thickness (67 micron), limiting its radiopacity. A specific X‐ray stent‐enhancing visualization technique, “StentBoost”, allowed clear visualization and understanding of the steps needed for an appropriate release and deployment of the aforementioned stent. © 2008 Wiley‐Liss, Inc.
