    1. Optical coherence tomography compared with fractional flow reserve guided approach in acute coronary syndromes: A propensity matched analysis

      Optical coherence tomography compared with fractional flow reserve guided approach in acute coronary syndromes: A propensity matched analysis

      Aim To compare in patients with ACS (Acute Coronary Syndromes) a PCI (Percutaneous Coronary Intervention) approach based on FFR (Fractional Flow Reserve) vs. one based on OCT (Optical Coherence Tomography). Methods and Results Consecutive patients admitted for ACS and treated with a PCI approach based on OCT or on FFR (recruited in two different studies) were compared and matched with propensity score analysis. Target Lesion revascularization (TLR) was the primary end point, while major adverse cardiovascular events [MACEs defined as the composite of death from cardiac causes, non- fatal MI, clinically driven target vessel revascularization (TVR), or re-hospitalization due to ...

    2. Optical coherence tomography appraisal of residual thrombus burden in patients with ST-segment elevation myocardial infarction undergoing intraprocedural versus post-stenting prolonged bivalirudin infusion. Rationale and design of the MATRIX (Minimizing A

      Optical coherence tomography appraisal of residual thrombus burden in patients with ST-segment elevation myocardial infarction undergoing intraprocedural versus post-stenting prolonged bivalirudin infusion. Rationale and design of the MATRIX (Minimizing A

      Aims: Residual thrombus accumulation around stent struts has been observed after the end of primary PCI and may represent a risk factor for acute stent thrombosis. The aim of this study is to test whether a strategy of prolonged bivalirudin infusion may reduce thrombosis of stent struts as compared to an intraprocedural only administration in subjects undergoing primary PCI. Methods and results: One hundred and sixty patients will be selected from the MATRIX (Minimizing Adverse Haemorrhagic Events by TRansradial Access Site and angioX) study with all the following inclusion criteria: a) STEMI patients undergoing primary PCI with stent implantation, b ...

    3. Comparison of Strut Coverage at Six Months by Optical Coherence Tomography with Everolimus Eluting Stent or Bare-Metal Stent Restenosis –vs- Stenosis of Non-Stented Atherosclerotic Narrowing (from the DESERT Study)

      Comparison of Strut Coverage at Six Months by Optical Coherence Tomography with Everolimus Eluting Stent or Bare-Metal Stent Restenosis –vs- Stenosis of Non-Stented Atherosclerotic Narrowing (from the DESERT Study)

      Incomplete struts coverage is a predictor of late stent thrombosis after drug eluting stent (DES) implantation in atherosclerotic lesions. The process of struts coverage in DES implanted for bare-metal stent (BMS) restenosis has never been described. Thirty-two patients with stable coronary artery disease were consecutively selected, 11 with BMS restenosis (group A) and 21 with de-novo atherosclerotic lesions (group B). All patients underwent everolimus eluting stent implantation; coronary angiography and optical coherence tomography (OCT) were performed at 6-month follow-up. Percentage difference in struts coverage between the two groups was the primary end-point. A total of 85773 struts (17891 in group ...

    4. The traumatic effect of balloon dilatation on neointimal hyperplasia: what we did not see before optical coherence tomography

      The traumatic effect of balloon dilatation on neointimal hyperplasia: what we did not see before optical coherence tomography
      A 79-year-old patient was referred to our cardiac care unit for unstable angina. He had a history of diabetes and hypercholesterolaemia and 5 months earlier he had undergone percutaneous coronary intervention of the proximal left anterior descending with bare metal stent implantation because of unstable angina. One month after stent implantation clopidogrel was discontinued because of a cutaneous allergy. Coronary angiography showed a severe in-stent restenosis of the proximal left anterior descending (figure 1A); taking …
