Optimization of Stent Deployment by Intravascular Ultrasound
Intravascular ultrasound (IVUS) is a useful diagnostic method that provides valuable information in addition to angiography regarding the coronary vessel lumen, dimensions, plaque burden, and characteristics. The major use of IVUS in coronary intervention is to guide interventional strategies and assess optimal stent deployment. Since the introduction of the drug-eluting stent (DES), concerns a...
متن کاملComparison of quantitative coronary angiography, intravascular ultrasound, and coronary pressure measurement to assess optimum stent deployment.
BACKGROUND Although intravascular ultrasound (IVUS) is the present standard for the evaluation of optimum stent deployment, this technique is expensive and not routinely feasible in most catheterization laboratories. Coronary pressure-derived myocardial fractional flow reserve (FFRmyo) is an easy, cheap, and rapidly obtainable index that is specific for the conductance of the epicardial coronar...
متن کاملIntravascular ultrasound after low and high inflation pressure coronary artery stent implantation.
OBJECTIVES We sought to characterize the differences seen after low or high pressure coronary artery stent deployment as assessed by intravascular ultrasound. BACKGROUND Until 1992, the success of stent deployment was assessed by angiographic criteria only, but in 1993 the procedure was expanded to include postprocedural single-use intravascular ultrasound imaging. Ultrasound criteria for suc...
متن کاملThe challenge of in-stent restenosis: insights from intravascular ultrasound.
The effectiveness of coronary stents in reducing angioplasty restenosis rates in de novo and restenotic lesions and their use without systemic anticoagulation prompted widespread acceptance of this technology. Despite these achievements, recurrence of luminal narrowing due to in-stent restenosis (ISR) occurs in a relatively high percentage of cases, when stents are implanted in complex lesions,...
متن کاملFractional flow reserve compared with intravascular ultrasound guidance for optimizing stent deployment.
BACKGROUND Determination of fractional flow reserve (FFR) has been proposed as a means to assess stent deployment. In this prospective, multicenter trial, we evaluate the use of FFR to optimize stenting by comparing it with standard intravascular ultrasound (IVUS) criteria. METHODS AND RESULTS Eighty-four stable patients with isolated coronary lesions underwent coronary stent deployment start...
