BACKGROUND - Small stent area and residual inflow/outflow disease have been reported as the strongest intravascular ultrasound (IVUS) predictors of early stent thrombosis (ST) in patients with stable angina. IVUS predictors of early ST in patients with acute myocardial infarction have not been studied. METHODS AND RESULTS - In the Harmonizing Outcomes with Revascularization and Stents in Acute ...
Clinical Trial | By Kang SJ, Ahn JM, Song H et al.
BACKGROUND - We assessed the optimal intravascular ultrasound (IVUS) stent area to predict angiographic in-stent restenosis (ISR) after sirolimus-eluting stent implantation for unprotected left main coronary artery (LM) disease. METHODS AND RESULTS - A total of 403 patients treated with single- or 2-stent strategies (crushing and T-stent) had immediate poststenting IVUS and 9-month follow-up angiograp...

AIMS - Although some recent guidelines recommend an early invasive strategy for non-ST-segment elevation acute coronary syndrome (NSTEACS), several studies have failed to identify any benefit for very early intervention for NSTEACS. The no-reflow phenomenon may inhibit the expected benefit from very early recanalization for NSTEACS subjects. The aim of this study was to investigate whether optical coherence tomography (OCT...
Clinical Trial | By Sonoda S, Morino Y, Ako J et al.
OBJECTIVES - We assessed the predictive value of minimum stent area (MSA) for long-term patency of sirolimus-eluting stents (SES) implantation compared to bare metal stents (BMS). BACKGROUND - Although MSA is a consistent predictor of in-stent restenosis, its predictive value in BMS is still limited because of biologic variability in the restenosis process. METHODS - From t...
Clinical Trial | By Bezerra HG, Attizzani GF, Sirbu V et al.
OBJECTIVES - We compared intravascular ultrasound (IVUS) and 2 different generations of optical coherence tomography (OCT)-time-domain OCT (TD-OCT) and frequency-domain OCT (FD-OCT)-for the assessment of coronary disease and percutaneous coronary intervention (PCI) using stents. BACKGROUND - OCT is a promising light-based intravascular imaging modality with higher resolution than IVUS...
OCT compared with IVUS in a coronary lesion assessment: the OPUS-CLASS study
Clinical Trial | By Kubo T, Akasaka T, Shite J et al.
OBJECTIVES - The aim of this study was to investigate the reliability of frequency domain optical coherence tomography (FD-OCT) for coronary measurements compared with quantitative coronary angiography (QCA) and intravascular ultrasound (IVUS). BACKGROUND - Accurate luminal measurement is expected in FD-OCT because this technology offers high resolution and excellent contrast between lumen and ...
Clinical Trial | By Okamura T, Onuma Y, Garcia-Garcia HM et al.
AIMS - The objective of this study is to evaluate the feasibility and safety of imaging human coronary arteries in vivo by optical frequency domain imaging (OFDI) in comparison to intravascular ultrasound (IVUS). OFDI has been recently developed to overcome the limitations of conventional time-domain optical coherence tomography (OCT), namely the need for proximal balloon occlusion. The Terumo-OFDI system is capable of acqu...
Review Article | By Ahn JM, Kang SJ, Park SJ et al.
There are conflicting data regarding the benefit of intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) over angiography-guided PCI. Since the last meta-analysis was published, several new studies have been reported. We performed a comprehensive meta-analysis to evaluate the clinical impact of IVUS-guided PCI with drug-eluting stent compared with conventional angiography-guided PCI. This meta-analysis includ...
Clinical Trial | By F Alfonso, MJ Pérez-Vizcayno, J Cuesta et al.
OBJECTIVES - This study sought to compare the long-term safety and efficacy of drug-eluting balloons (DEB) and everolimus-eluting stents (EES) in patients with in-stent restenosis (ISR) of drug-eluting stents (DES). BACKGROUND - Treatment of patients with DES-ISR remains a challenge. METHODS - The RIBS IV (Restenosis Intra-Stent of Drug-Eluting Stents: Drug-Eluting ...
