    1. Culprit plaque morphology in STEMI – an optical coherence tomography study: insights from the TOTAL-OCT substudy

      Culprit plaque morphology in STEMI – an optical coherence tomography study: insights from the TOTAL-OCT substudy
      Aims: Our aim was to compare stenosis severity and plaque content between STEMI culprit lesions with intact fibrous cap (IFC) and those with plaque rupture (PR) in a prospective study. Methods and results: We evaluated 93 patients undergoing OCT and thrombectomy as part of a prospective substudy of the TOTAL (ThrOmbecTomy versus PCI ALone) trial. Culprit lesion morphology was assessable by OCT in 70/93 (75.3%). IFC was found ...

    2. Evaluation of Below-the-Knee Drug-Eluting Stents With Frequency-Domain Optical Coherence Tomography: Neointimal Hyperplasia and Neoatherosclerosis

      Evaluation of Below-the-Knee Drug-Eluting Stents With Frequency-Domain Optical Coherence Tomography: Neointimal Hyperplasia and Neoatherosclerosis
      Purpose: To report the use of intravascular frequency-domain optical coherence tomography (FD-OCT) to detect and characterize in-stent neointimal tissue following infrapopliteal drug-eluting stent (DES) placement in patients suffering from critical limb ischemia. Methods: This prospective study included 12 patients (7 men; mean age 72.87.2 years) who had previously received 21 infrapopliteal sirolimus- or everolimus-eluting stents. The patients returned for regular angiographic follow-up or presented with clinical relapse of ...

    3. In the search of coronary calcium

      In the search of coronary calcium
      The recognition of coronary artery calcium (CAC) as an indicator of coronary artery disease for more than 30years has created a great interest in methods for its accurate assessment. In this review we present the imaging techniques capable of detecting CAC and discuss their current status in clinical practice. The first non-invasive CAC imaging method was chest radiography, although early recognized as insensitive. Fluoroscopy and digital fluoroscopy improved CAC detection ...

    5. Mechanism of a reproducible accordion phenomenon: insights by optical coherence tomography visualization

      Mechanism of a reproducible accordion phenomenon: insights by optical coherence tomography visualization
      Pseudostenosis or ‘accordion phenomenon’ is a transient angiographic multifocal filling defect observed mostly during percutaneous coronary intervention, mainly in tortuous vessels. We describe a case of a reproducible accordion effect in the right coronary artery accompanied by only a mild clinical syndrome. Optical coherence tomography evaluation of this strange and fortunately completely reversible phenomenon is discussed.

    6. An optical coherence tomography study of two new generation stents with biodegradable polymer carrier, eluting paclitaxel vs. biolimus-A9

      An optical coherence tomography study of two new generation stents with biodegradable polymer carrier, eluting paclitaxel vs. biolimus-A9
      Background Tissue coverage and strut apposition of drug eluting stents (DES), which can be assessed with optical coherence tomography (OCT), may be associated with late stent thrombosis (LST). Methods Prospective observational angiographic and OCT follow-up at 6months post-implantation of a biolimus-A9 eluting stent (BES) vs. a paclitaxel eluting stent (PES), with biodegradable polymer carriers. The primary outcome was the percent difference of uncovered struts between BESs and PESs. Results A ...

    7. Neointimal tissue rupture as a mechanism of myocardial infarction very late following implantation of bare metal stents. Insights from optical coherence tomography

      Neointimal tissue rupture as a mechanism of myocardial infarction very late following implantation of bare metal stents. Insights from optical coherence tomography
      A 49-year-old male presented with an ST-elevation acute myocardial infarction 6 years following implantation of a bare metal stent (BMS) in the left anterior descending artery (LAD). Coronary angiography (CAG), before primary angioplasty disclosed severe restenosis of the stent (A, arrow). In B–F, five successive optical coherence tomography (OCT) image frames acquired at the level of restenosis, show complete burying of stent struts (asterisks), under thick neointimal tissue with ...

    8. Neointimal coverage and stent strut apposition six months after implantation of a paclitaxel eluting stent in acute coronary syndromes: An optical coherence tomography study

      Neointimal coverage and stent strut apposition six months after implantation of a paclitaxel eluting stent in acute coronary syndromes: An optical coherence tomography study
      Abstract: Objectives: Prospective optical coherence tomography (OCT) study of strut apposition and neointimal hyperplasia thickness (NIH) of a paclitaxel eluting stent (PES), (Infinium, Sahajanand Medical Technologies Pvt Ltd.).Background: Few data exist concerning neointimal coverage of PES. Uncovered and malapposed struts are more common following stenting in acute coronary syndromes (ACS) than in non-ACS lesions.Methods: All consecutive patients with ACS, treated with the above PES for single native coronary ...

    10. Late asymptomatic sirolimus-eluting stent fracture in a female with systemic lupus erythematosus

      Abstract: We report a case of a sirolimus eluting (Cypher, Johnson-Johnson) stent fracture (SF) incidentally depicted 3 years post PCI in an asymptomatic female with systemic lupus erythematosus (SLE). The vessel was assessed with intravascular ultrasound (IVUS) and optical coherence tomography (OCT). Different imaging modalities results are presented. OCT may offer superior imaging of SF compared to fluoroscopy and IVUS and might prove useful for the detailed assessment and tailored ...

    11. Intimal hyperplasia by optical coherence tomography after BMS and DES implantation in the same artery

      Drug eluting stents (DES) by inhibiting neointimal proliferation are associated with a much lower in-stent restenosis rate compared with bare metal stents (BMS). Studies supporting these data have included patients in whom either DES or BMS were implanted but not both. What has rarely been described is the vessel response against both types of stents in the same patient. This case illustrates the difference in neointimal hyperplasia after the deployment ...
