Abstract
Intracoronary ultrasound observations during stent implantation.
Highlights
ObjectivesThe purpose of this study was to compare the observations of Intravascular ultrasound (IVUS) with standard angiography after stent implantation and to develop recommendations for guiding stent implantation by IVUS
First step is after a satisfactory angiographic result; final step is after final dilatation using the maximum-size baioon guided by intravascular ultrasound measurement
Despite adequate angiographic results with a step up into the stented area and a step down into the distal segment of the artery, Intravascular ultrasound (IVUS) imaging demonstrated a high frequency of incompletely expanded stents. These results suggest that some of the complications of subacute thrombosis or restenosis may be due to inadequate stent expansion during initial deployment
