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 Kubo T, Shinke T, OPINION Investigators
AIMS - Optical frequency domain imaging (OFDI) is a recently developed, light-based, high-resolution intravascular imaging technique. Intravascular ultrasound (IVUS) is a widely used, conventional imaging technique for guiding percutaneous coronary intervention (PCI). We aimed to demonstrate the non-inferiority of OFDI-guided PCI compared with IVUS-guided PCI in terms of clinical outcomes. METHODS AND...
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 ...
Clinical Trial | By TM Rhee, JM Lee, ES Shin et al.
OBJECTIVES - The aim of this study was to investigate the impact of optimizing procedure-related factors during drug-eluting balloon (DEB) angioplasty on clinical outcomes of drug-eluting stent in-stent restenosis (ISR). BACKGOURND - Although DEB angioplasty is recommended as a reasonable option for ISR, recurrent target lesion failure (TLF) still occurs in many patients after DEB angioplasty. ...
Clinical Trial | By T Lefèvre, M Haude, FJ Neumann et al.
OBJECTIVES - The authors aimed to compare long-term data of an ultrathin cobalt-chromium stent with passive silicon carbide coating and an active biodegradable polymer that releases sirolimus (O-SES) (Orsiro, BIOTRONIK, Bülach, Switzerland) with the durable polymer-based Xience Prime everolimus-eluting stent (X-EES) (Abbott Vascular, Santa Clara, California). BACKGOURND - Biodegradable poly...
High-Sensitivity Troponins and Outcomes After Myocardial Infarction
Clinical Trial | By Odqvist M, Andersson PO, Tygesen H et al.
BACKGROUND - It remains unknown how the introduction of high-sensitivity cardiac troponin T (hs-cTnT) has affected the incidence, prognosis, and use of coronary angiographies and revascularizations in patients with myocardial infarction (MI). OBJECTIVES - The aim of this study was to investigate how the incidence of MI and prognosis after a first MI was affected by the introduction of hs-cTnT. METHOD...
