      EuOptical coherence tomography findings: insights from the “randomised multicentre trial investigating angiographic outcomes of hybrid sirolimus-eluting stents with biodegradable polymer compared with everolimus-eluting stents with durable polymer in chro

      Aims: The PRISON IV trial investigated the next-generation sirolimus-eluting stent (SES) with ultra-thin struts and biodegradable polymer against the second-generation everolimus-eluting stent (EES) with thin struts and durable polymer in patients with successfully recanalised chronic total occlusions (CTO). In this study, we examined the secondary optical coherence tomography endpoints. Methods and results: The main PRISON IV trial randomised 330 patients to either SES or EES. At nine months, 281 (85%) patients underwent repeat angiography. Of these, 60 consecutive patients received optical coherence tomography divided over both stent groups. The mean number of struts analysed was 750±337 and 633±358 ...

      COmplex coronary Bifurcation lesions: RAndomized comparison of a strategy using a dedicated self-expanding biolimus-eluting stent versus a culotte strategy using everolimus-eluting stents: primary results of the COBRA trial

      Aims: We aimed to compare healing responses with optical coherence tomography, and clinical and angiographic outcome after treatment of coronary bifurcation lesions with a dedicated stent versus aconventional culotte technique. Methods and results: Forty patients with true and complex coronary bifurcation lesions were randomly assigned to treatment with the Axxess™ bifurcation stent in the proximal main vessel (MV) and additional BioMatrix™ stents in the branches (Biosensors Europe SA, Morges, Switzerland), versus a culotte technique using XIENCE™ stents (Abbott Vascular, Santa Clara, CA, USA). The primary endpoint of percentage of uncovered struts at nine months was similar with the dedicated strategy ...

      STACCATO (Assessment of Stent sTrut Apposition and Coverage in Coronary ArTeries with Optical coherence tomography in patients with STEMI, NSTEMI and stable/unstable angina undergoing everolimus vs. biolimus A9-eluting stent implantation): a randomised co

      Aims: To compare tissue coverage in coronary lesions stented with durable fluoropolymer-coated everolimus-eluting stents (EES) vs. biodegradable polymer-coated biolimus A9-eluting stents (BES). Methods and results: Sixty-four patients (64 lesions) with de novo coronary artery lesions were randomised to percutaneous treatment with XIENCE® EES (Abbott Vascular, Santa Clara, CA, USA) vs. BioMatrix™ BES (Biosensors, Morges, Switzerland). The primary endpoint was the percentage of uncovered struts, as assessed with OCT, at nine months. The average percentage of uncovered struts was significantly lower with EES (4.3±4.8% vs. 8.7±7.8% with BES, p=0.019). There was no difference ...

    6. Optical coherence tomography study of healing characteristics of paclitaxel-eluting balloons vs. everolimus-eluting stents for in-stent restenosis: the SEDUCE (Safety and Efficacy of a Drug elUting balloon in Coronary artery rEstenosis) randomised clinica

      Optical coherence tomography study of healing characteristics of paclitaxel-eluting balloons vs. everolimus-eluting stents for in-stent restenosis: the SEDUCE (Safety and Efficacy of a Drug elUting balloon in Coronary artery rEstenosis) randomised clinica

      Aims: Little is known about the respective healing responses and clinical efficacy and safety of drug-eluting balloons (DEB) and the second generation of drug-eluting stents (DES) when used to treat in-stent restenosis (ISR). In this study, we set out to compare prospectively the healing characteristics, as assessed by optical coherence tomography (OCT), of DEB versus DES after treatment of ISR in bare metal stents (BMS). Methods and results: Fifty patients with BMS ISR were randomised to treatment with a paclitaxel-eluting balloon vs. an everolimus-eluting stent (EES). The primary endpoint was the percentage of uncovered struts, assessed with OCT at nine ...

    7. Automated detection and quantification of clusters of malapposed and uncovered intracoronary stent struts assessed with optical coherence tomography

      Automated detection and quantification of clusters of malapposed and uncovered intracoronary stent struts assessed with optical coherence tomography

      To date, accurate quantification and localization of malapposed and uncovered struts needs manual and time consuming analysis of large datasets. To develop an algorithm for automated detection and quantification of clusters of malapposed and uncovered struts in optical coherence tomography (OCT) pullbacks, including comprehensive information about their three-dimensional spatial distribution. 64 lesions in 64 patients treated with drug-eluting stent underwent assessment with OCT immediately after implantation and at 9-month follow-up (55 patients). An automated algorithm was used to detect and quantify stent strut malapposition at baseline and coverage at follow-up on an individual strut level. We subsequently applied an algorithm ...

    8. Healing course of acute vessel wall injury after drug-eluting stent implantation assessed by optical coherence tomography

      Healing course of acute vessel wall injury after drug-eluting stent implantation assessed by optical coherence tomography

      BACKGROUND: Vessel wall injury after drug-eluting stent (DES) implantation can be characterized in detail by optical coherence tomography (OCT). Little is known about the healing course of these phenomena. METHODS AND RESULTS: In 62 lesions (62 patients), the incidence of acute vessel trauma was assessed in the stented region and the edge segments immediately after DES implantation. The healing course of these injuries was assessed at 9-month OCT follow-up using a software algorithm allowing for reliable spatial comparison of baseline and follow-up cross-sectional images. Tissue prolapse (TP) and tissue protrusions were detected in 81 and 35% of lesions, respectively. A ...

    9. Very late bare metal stent thrombosis due to neoatherosclerotic plaque rupture: an optical coherence tomography finding

      Very late bare metal stent thrombosis due to neoatherosclerotic plaque rupture: an optical coherence tomography finding

      Very late stent thrombosis (VLST) is a rare but potentially catastrophic complication occurring after percutaneous coronary intervention. The mechanisms involved in VLST in bare metal stents (BMS) are poorly understood. A 50-year-old man presented with an inferior ST-elevation myocardial infarction. There was a history of percutaneous coronary intervention of the right coronary artery with a BMS 7 years ago. Emergency coronary angiography revealed acute stent thrombosis within the right coronary artery stent (figure 1) (panel A). After aspiration thrombectomy, optical coherence tomography was performed (panel I–V). The optical coherence tomography findings in this case support the growing evidence that ...
