Intravascular ultrasound (IVUS) offers tomographic images of the coronary artery, helping physicians to refine drug-eluting stent (DES) implantation in angiographically complex lesions. However, controversy exists regarding whether the routine use of IVUS in short-length lesions leads to improved clinical outcomes after DES implantation. Therefore, we evaluated the usefulness of IVUS in predicting major adverse cardiac ...
Differential prognostic effect of intravascular ultrasound use according to implanted stent length
Original Research | By Ahn JM, Han S, Park YK et al.
It is unknown whether the use of intravascular ultrasound (IVUS) guidance during percutaneous coronary intervention can attenuate the stent length effect on clinical outcomes. The aim of the present study was to determine the differential prognostic effect of IVUS according to the implanted stent length. We enrolled 3,244 consecutive patients from the Interventional Cardiology Research In-cooperation Society-Drug-Eluting St...

Despite the usefulness of intravascular ultrasound (IVUS) in percutaneous coronary intervention (PCI), the impact of IVUS guidance on clinical outcomes, particularly for chronic total occlusion (CTO) intervention, has rarely been studied. We sought to investigate the clinical usefulness of IVUS-guided CTO intervention with second-generation drug-eluting stent implantation. From 2007 to 2009, a total of 2,568 patients we...

IMPORTANCE - Intracoronary pressure wire-derived measurements of fractional flow reserve (FFR) and intravascular ultrasonography (IVUS) provide functional and anatomical information that can be used to guide coronary stent implantation. Although these devices are widely used and recommended by guidelines, limited data exist about their effect on clinical end points. OBJECTIVE - To determine the...

OBJECTIVE - Major limitation for the use of stent in the treatment of coronary artery disease is development of stent restenosis. The impact of intravascular ultrasound (IVUS) guidance during drug eluting stent (DES) implantation is presently not yet well established. PATIENTS AND METHODS - For the present study, we included 30 patients who received DES with IVUS-guided stenting (Group A...

Despite the valuable role of intravascular ultrasound (IVUS) guidance in percutaneous coronary interventions (PCIs), its impact on clinical outcomes remains debatable. The aim of the present study was to compare the outcomes of PCIs guided by IVUS versus angiography in the contemporary era on inhospital outcomes in an unrestricted large, nationwide patient population. Data were obtained from the Nationwide Inpatient S...

AIMS - Our aim was to compare the outcomes of complete revascularisation (CR) and incomplete revascularisation (IR) in multivessel coronary artery disease (CAD), with and without intravascular ultrasound (IVUS) guidance, in the drug-eluting stent (DES) era. METHODS AND RESULTS - Overall, 2,132 consecutive patients with multivessel CAD, defined as at least two epicardial vessels with >70% s...

OBJECTIVES - To evaluate the long-term outcomes of patients with ostial lesions who underwent percutaneous coronary intervention (PCI) with and without the use of intravascular ultrasound (IVUS). BACKGROUND - A higher rate of adverse cardiac events is associated with PCI of ostial lesions as compared with nonostial disease. METHODS - From 7/2002 to 8/2010, 225 patients w...
