    1. Comparison between intermediate and severe coronary stenoses and clinical outcomes of an OCT-guided PCI strategy

      Comparison between intermediate and severe coronary stenoses and clinical outcomes of an OCT-guided PCI strategy

      Aims: We compared optical coherence tomography (OCT) features of intermediate and severe coronary stenoses in patients with stable angina and acute coronary syndrome (ACS), and tested the clinical impact of an OCT-based strategy for treating intermediate stenoses. Methods: The study enrolled 135 consecutive patients with either ACS or stable angina and a single de-novo coronary stenosis. Patients were divided into two groups: intermediate stenosis defined as quantitative coronary angiography percentage narrowing less than 70%, or presence of angiographic vessel haziness and severe stenosis with percentage narrowing more than 70%. OCT was performed to assess features of plaque vulnerability and to ...

    2. Serial optical coherence tomography imaging of ACS-causing culprit plaques

      Serial optical coherence tomography imaging of ACS-causing culprit plaques

      Aims: The aim of this study was to understand better the mechanisms of repair of plaque complications causing acute coronary syndrome. Methods and results: We used OCT in the acute phase and at follow-up (one to seven months) to investigate the plaque healing in 10 culprit plaques: five ruptured fibrous cap (RFC) and five intact fibrous cap (IFC) which were not treated with stent deployment and caused ST-segment elevation myocardial infarction (n=8) and non-STEMI (n=2). At follow-up OCT, the margins of the evacuated cavity in RFC plaques showed a smooth surface and a morphology similar to that of ...

      Suboptimal stent deployment is associated with subacute stent thrombosis: Optical Coherence Tomography insights from a multicenter matched study. From the CLI Foundation investigators: the CLI-THRO study

      Background Acute or sub-acute stent thrombosis (ST) is a well described complication usually causing acute coronary syndromes (ACS) and in the worst case scenario sudden cardiac death. In this study we aimed at exploring the potential role of optical coherence tomography (OCT) in the understanding of the mechanism of ST. Methods Twenty-one consecutive patients, after ACS due to a definite sub-acute ST, were assessed with OCT and matched 1:2 with 42 patients undergoing OCT for scheduled follow-up. OCT assessment was focused on features indicative of non-optimal stent deployment: under-expansion, malapposition, edge dissection and reference lumen narrowing. Results OCT revealed ...
