      Serial Assessment of Tissue Precursors and Progression of Coronary Calcification Analyzed by Fusion of IVUS and OCT
      Objectives The aim of this study was to assess calcium growth with fused grayscale intravascular ultrasound (IVUS), IVUSvirtual histology, and optical coherence tomography (OCT) from baseline to 5-year follow-up in patients treated with bioresorbable vascular scaffolds. Background IVUS and OCT have individual strengths in assessing plaque composition and volume. Fusion of images obtained using these methods could potentially aid in coronary plaque assessment. Methods Anatomic landmarks and endoluminal radiopaque markers ...

      Serial 5-Year Evaluation of Side Branches Jailed by Bioresorbable Vascular Scaffolds Using 3-Dimensional Optical Coherence Tomography
      Background The long-term fate of Absorb bioresorbable vascular scaffold (Abbott Vascular, Santa Clara, CA) struts jailing side branch ostia has not been clarified. We therefore evaluate serially (post-procedure and at 6 months, 1, 2, 3, and 5 years) the appearance and fate of jailed Absorb bioresorbable vascular scaffold struts. Methods and Results We performed 3-dimensional optical coherence tomographic analysis of the ABSORB Cohort B trial (A Clinical Evaluation of the ...

      EuroIntervention Automated characterisation of lipid core plaques in vivo by quantitative optical coherence tomography tissue type imaging
      Aims: Qualitative criteria for plaque tissue characterisation by OCT are well established, but quantitative methods lack systematic validation in vivo . High optical attenuation coefficient t has been associated with unstable plaque features, such as lipid core. The purpose of this study was to validate optical coherence tomography (OCT) attenuation imaging for tissue characterisation in vivo , specifically to detect lipid core in coronary atherosclerotic plaques, and to evaluate quantitatively the ability ...

      Comparison of acute expansion of bioresorbable vascular scaffolds versus metallic drug-eluting stents in different degrees of calcification
      Objectives The acute expansion of bioresorbable vascular scaffolds (BRS) and drug-eluting stents (DES) in lesions with different extent of calcification was compared by Optical Coherence Tomography (OCT). Background The acute mechanical performance of polymeric BRS in calcified lesions is poorly understood. Methods Acute device performance in lesions treated with either BRS( N =50) or DES ( N =50) was compared using Optical Coherence Tomography (OCT). According to angiographic degree of calcification ...

      Everolimus-Eluting Bioresorbable Vascular Scaffolds implanted in Coronary Bifurcation Lesions
      Background Limited data are available on bioresorbable vascular scaffolds (BVS) performance in bifurcations lesions and on the impact of BVS wider struts on side-branch impairment. Methods Patients with at least one coronary bifurcation lesion involving a side-branch 2 mm in diameter and treated with at least one BVS were examined. Procedural and angiographic data were collected and a dedicated methodology for off-line quantitative coronary angiography (QCA) in bifurcation was applied ...

      Safety of optical coherence tomography in daily practice: a comparison with intravascular ultrasound
      Aims Previous studies have reported the safety and feasibility of both time-domain optical coherence tomography (TD-OCT) and Fourier-domain OCT (FD-OCT) in highly selected patients and clinical settings. However, the generalizability of these data is limited, and data in unselected patient populations reflecting a routine cathlab practice are lacking. We compared safety of intracoronary FD-OCT imaging to intravascular ultrasound (IVUS) imaging in a large real-world series of consecutive patients who underwent ...

      Bioresorbable vascular scaffold treatment induces the formation of neointimal cap that seals the underlying plaque without compromising the luminal dimensions: a concept based on serial optical coherence tomography data
      Aims: To evaluate the implications of an Absorb bioresorbable vascular scaffold (Absorb BVS) on the morphology of the superficial plaques. Methods and results: Forty-six patients who underwent Absorb BVS implantation and 20 patients implanted with bare metal stents (BMS) who had serial optical coherence tomographic examination at baseline and follow-up were included in this analysis. The thin-capped fibroatheromas (TCFA) were identified in the device implantation regions and in the adjacent ...

      Incidence and potential mechanism of resolved, persistent and newly acquired malapposition three days after implantation of self-expanding or balloon-expandable stents in a STEMI population: insights from optical coherence tomography in the APPOSITION II
      Aims: The aim of the current study was to investigate the frequency and mechanisms of sequential incomplete stent apposition (ISA) changes such as persistent, resolved or newly acquired ISA during the first three days after primary PCI (pPCI) in a matched segment-level analysis, with the comparison between self-expanding and balloon-expandable stents assessed by optical coherence tomography (OCT). Methods and results: The current analysis is a substudy of the APPOSITION II ...

      Use of Intracoronary imaging in ST Elevation Myocardial Infarction with coronary artery aneurysm and very late stent thrombosis
      The use of Optical Coherence Tomography (OCT)-guided percutaneous coronary intervention (PCI) has been described in ST-Elevation Myocardial Infarction (STEMI) involving relatively simple culprit lesions [1]. Coronary artery aneurysms have a reported incidence of up to 4.9% among coronary angiograms performed and may present clinically as STEMI either from thrombus formation or embolic phenomena [2]. There has been limited experience described regarding the use of OCT in STEMI with ...

      Association of wall shear stress with long-term vascular healing response following bioresorbable vascular scaffold implantation
      Bioresorbable vascular scaffolds (BVS) could potentially overcome pitfalls of metal stents, such as late failure and neoatherosclerosis [1]. At the long-term follow-up of the everolimus-eluting BVS (Absorb BVS 1.0; Abbott Vascular, Santa Clara, CA), complete strut bioresorption accompanied by late luminal enlargement and development of a signal-rich layer covering underlying thrombogenic plaque components were observed by optical coherence tomography (OCT) 5 years after implantation [1,2]. The vascular architecture ...

      Early and late optical coherence tomography findings following everolimus-eluting bioresorbable vascular scaffold implantation in myocardial infarction: a preliminary report
      Introduction: Although bioresorbable vascular scaffolds (BVS) have been used with promising results in patients with stable and unstable angina, little is known about the acute vascular response following BVS implantation in myocardial infarction. We present angiographic and OCT findings from the first patients undergoing bioresorbable vascular scaffold (BVS) implantation for non-ST-elevation myocardial infarction (NSTEMI) or ST-elevation myocardial infarction (STEMI) in our institution. Methods: The first 5 patients with NSTEMI and ...
