    2. Scaffold and Edge Vascular Response Following Implantation of Everolimus-Eluting Bioresorbable Vascular Scaffold : A 3-Year Serial Optical Coherence Tomography Study

      Scaffold and Edge Vascular Response Following Implantation of Everolimus-Eluting Bioresorbable Vascular Scaffold : A 3-Year Serial Optical Coherence Tomography Study

      Objectives This study sought to investigate the in-scaffold vascular response (SVR) and edge vascular response (EVR) after implantation of an everolimus-eluting bioresorbable scaffold (BRS) using serial optical coherence tomography (OCT) imaging. Background Although studies using intravascular ultrasound have evaluated the EVR in metal stents and BRSs, there is a lack of OCT-based SVR and EVR assessment after BRS implantation. Methods In the ABSORB Cohort B (ABSORB Clinical Investigation, Cohort B) study, 23 patients (23 lesions) in Cohort B1 and 17 patients (18 lesions) in Cohort B2 underwent truly serial OCT examinations at 3 different time points (Cohort B1: post-procedure, 6 ...

      Long-term invasive follow-up of the everolimus-eluting bioresorbable vascular scaffold: five-year results of multiple invasive imaging modalities

      Aims: The Paradise Ultrasound Renal Denervation System is a next-generation catheter-based device which was used to investigate whether the target ablation area can be controlled by changing ultrasound energy and duration to optimise nerve injury while preventing damage to the arterial wall. Methods and results: Five ultrasound doses were tested in a thermal gel model. Catheter-based ultrasound denervation was performed in 15 swine (29 renal arteries) to evaluate five different doses in vivo , and animals were euthanised at seven days for histopathologic assessment. In the gel model, the peak temperature was highest in the low power-long duration (LP-LD) dose, followed ...

      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 native coronary segments. Within all regions, circumferential locations of TCFA and calcific tissues were identified, and the neointimal thickness was measured at follow-up. At six to 12-month follow-up, only 8 ...

    5. Qvanteq Bioactive Coronary Stent System First in Man (FIM) Clinical Investigation

      Qvanteq Bioactive Coronary Stent System First in Man (FIM) Clinical Investigation

      Objective of this First in Man study is to assess feasibility and safety of Qvanteq's bioactive coronary stent for treatment of stable coronary artery disease patients with de novo coronary artery stenosis in native vessels. The proprietary surface of Qvanteq's bioactive coronary stent improves the in-growth behavior of the stent in the treated vessel. In-vivo animal studies revealed fast in-growth (similar to BMS), which however is not resulting in excessive tissue overgrowth as observed in BMS but rather has an efficacy profile similar to drug-eluting stent (DES), meaning suppression of tissue overgrowth. This should reduce the risk of ...

    6. Serial 2-Dimensional and 3-Dimensional Optical Coherence Tomography Assessment of Overhanging Struts of Drug-Eluting Absorbable Metal Scaffold

      Serial 2-Dimensional and 3-Dimensional Optical Coherence Tomography Assessment of Overhanging Struts of Drug-Eluting Absorbable Metal Scaffold

      A 75-year-old woman with stable angina pectoris underwent percutaneous coronary intervention of the left anterior descending coronary artery, whereby a 3.25/16-mm paclitaxel-eluting absorbable metal scaffold (DREAMS, Biotronik, Bülach, Switzerland) was successfully implanted. Post-procedural angiography showed excellent results without pinching of the side branch ostium. The patient experienced no procedure-related complications, and was discharged 48 h after the procedure on dual antiplatelet therapy. Optical coherence tomography (OCT) (LightLab Imaging, Westford, Massachusetts) was performed post-procedure and at 12 months follow-up. Post-procedurally, the scaffold was well expanded with good apposition of struts to the vessel wall, and a side branch ...

      Serial optical frequency domain imaging in STEMI patients: the follow-up report of TROFI study

      Aims To investigate the incidence of incomplete stent apposition and to explore the impact of the presence of thrombus and protruding plaque after stent implantation on neointima formation at follow-up in ST-segment elevation myocardial infarction (STEMI) patients with serial optical frequency domain imaging (OFDI) investigations. Methods and results In a multi-centre study, 141 patients with ST elevation myocardial infarction <12 h from onset were randomized to either PPCI with thrombectomy (TB) using an Eliminate catheter (TB: n = 71) or without TB (non-TB: n = 70). OFDI after drug-eluting stenting was performed using TERUMO OFDI system. Per protocol, at follow-up 49 patients ...

    9. In vivo evaluation of neointimal healing after stenting with optical coherence tomography (Thesis)

      In vivo evaluation of neointimal healing after stenting with optical coherence tomography (Thesis)

      Ischemic heart disease is still today the first cause of mortality in the world, especially in the developed countries. The vast majority of cases are due to atherosclerosis, a complex systemic degenerative process resulting in cholesterol accumulation in the extra-cellular space of the arterial intima, with inflammation, foam-cells formation, and necrosis. The clinical manifestations of coronary atherosclerosis comprise from stable angina, due to flow-limiting stenosis of the artery, to acute myocardial infarction or sudden death, when the atheroma gets complicated by thrombotic phenomena. The first revolution in the treatment of this disease came in 1977, when Andreas Grüntzig performed ...

    10. Effect of the Endothelial Shear Stress Patterns on Neointimal Proliferation Following Drug-Eluting Bioresorbable Vascular Scaffold Implantation : An Optical Coherence Tomography Study

      Effect of the Endothelial Shear Stress Patterns on Neointimal Proliferation Following Drug-Eluting Bioresorbable Vascular Scaffold Implantation : An Optical Coherence Tomography Study

      Objectives The goal of this study was to investigate the effect of endothelial shear stress (ESS) on neointimal formation following an Absorb bioresorbable vascular scaffold (BVS) (Abbott Vascular, Santa Clara, California) implantation. Background Cumulative evidence, derived from intravascular ultrasound–based studies, has demonstrated a strong association between local ESS patterns and neointimal formation in bare-metal stents, whereas in drug-eluting stents, there are contradictory data about the effect of ESS on the vessel wall healing process. The effect of ESS on neointimal development following a bioresorbable scaffold implantation remains unclear. Methods Twelve patients with an obstructive lesion in a relatively straight ...

      3D optical coherence tomography: new insights into the process of optimal rewiring of side branches during bifurcational stenting

      Aims: We describe three-dimensional optical coherence tomography (3D-OCT) guided bifurcation stenting and the clinical utility of 3D-OCT. Methods and results: Twenty-two consecutive patients who underwent OCT examination to confirm the recrossing position after stent implantation in a bifurcation lesion were enrolled. Frequency domain OCT images were obtained to check the recrossing position and 3D reconstructions were performed off-line. The recrossing position was clearly visualised in 18/22 (81.8%) cases. In 13 cases, serial 3D-OCT could be assessed both before and after final kissing balloon post-dilation (FKBD). We divided these cases into two groups according to the presence of the ...

      Fusion of optical coherence tomographic and angiographic data for more accurate evaluation of the endothelial shear stress patterns and neointimal distribution after bioresorbable scaffold implantation: comparison with intravascular ultrasound-derived rec

      Intravascular ultrasound (IVUS)-based reconstructions have been traditionally used to examine the effect of endothelial shear stress (ESS) on neointimal formation. The aim of this analysis is to compare the association between ESS and neointimal thickness (NT) in models obtained by the fusion of optical coherence tomography (OCT) and coronary angiography and in the reconstructions derived by the integration of IVUS and coronary angiography. We analyzed data from six patients implanted with an Absorb bioresorbable vascular scaffold that had biplane angiography, IVUS and OCT investigation at baseline and 6 or 12 months follow-up. The IVUS and OCT follow-up data were ...

    13. Flow disturbances in stent-related coronary evaginations: a computational fluid-dynamic simulation study

      Flow disturbances in stent-related coronary evaginations: a computational fluid-dynamic simulation study

      Aims: Angiographic ectasias and aneurysms in stented segments have been associated with late stent thrombosis. Using optical coherence tomography (OCT), some stented segments show coronary evaginations reminiscent of ectasias. The purpose of this study was to explore, using computational fluid-dynamic (CFD) simulations, whether OCT-detected coronary evaginations can induce local changes in blood flow. Methods and results: OCT-detected evaginations are defined as outward bulges in the luminal vessel contour between struts, with the depth of the bulge exceeding the actual strut thickness. Evaginations can be characterised cross ectionally by depth and along the stented segment by total length. Assuming an ellipsoid ...
