    1. OCT guidance during stent implantation in primary Pci: A randomized multicenter study with nine months of optical coherence tomography follow-up

      OCT guidance during stent implantation in primary Pci: A randomized multicenter study with nine months of optical coherence tomography follow-up

      Aims To assess the possible merits of optical coherence tomography (OCT) guidance in primary percutaneous coronary intervention (pPCI). Methods and results 201 patients with ST-elevation myocardial infarction (STEMI) were enrolled in this study. Patients were randomized either to pPCI alone (angio-guided group, n = 96) or to pPCI with OCT guidance (OCT-guided group, n = 105) and also either to biolimus A9 or to everolimus-eluting stent implantation. All patients were scheduled for nine months of follow-up angiography and OCT study. OCT guidance led to post-pPCI optimization in 29% of cases (59% malapposition and 41% dissections). No complications were found related to the ...

    2. Radial artery neointimal hyperplasia after transradial PCI—Serial optical coherence tomography volumetric study

      Radial artery neointimal hyperplasia after transradial PCI—Serial optical coherence tomography volumetric study

      Aims Transradial catheterization (TRC) is a dominant access site for coronary catheterization and percutaneous coronary interventions (PCI) in many centers. Previous studies reported higher intimal thickness of the radial artery (RA) wall in patients with a previous history of TRC. In this investigation the aim was to assess the intimal changes of RA using the optical coherence tomography (OCT) intravascular imaging in a serial manner. Methods and results 100 patients with the diagnosis of non-ST-elevation myocardial infarction (nSTEMI) treated by PCI were enrolled (6 patients were excluded from this analysis because of occluded RA at follow-up [2 patients] and insufficient ...

    3. Volumetric quantification of fibrous caps using intravascular optical coherence tomography

      Volumetric quantification of fibrous caps using intravascular optical coherence tomography

      The rupture of thin-cap fibroatheroma accounts for most acute coronary events. Optical Coherence Tomography (OCT) allows quantification of fibrous cap (FC) thickness in vivo. Conventional manual analysis, by visually determining the thinnest part of the FC is subject to inter-observer variability and does not capture the 3-D morphology of the FC. We propose and validate a computer-aided method that allows volumetric analysis of FC. The radial FC boundary is semi-automatically segmented using a dynamic programming algorithm. The thickness at every point of the FC boundary, along with 3-D morphology of the FC, can be quantified. The method was validated against ...
