    1. Variable underlying morphology of culprit plaques associated with ST-elevation myocardial infarction: an optical coherence tomography analysis from the SMART trial

      Variable underlying morphology of culprit plaques associated with ST-elevation myocardial infarction: an optical coherence tomography analysis from the SMART trial

      Aims The objective was to assess in vivo culprit lesion morphologies that caused ST-segment elevation myocardial infarction (STEMI) using optical coherence tomography (OCT). Methods and results Culprit lesions in 80 patients presenting within 6 h of STEMI onset from the CompariSon of Manual Aspiration with Rheolytic Thrombectomy in patients undergoing primary PCI (SMART) trial were evaluated. Underlying morphology of 64 culprit lesions was identifiable by OCT and included 37 lesions with plaque rupture, 25 lesions without plaque rupture, and 2 lesions with calcified nodules. Patients with plaque rupture tended to be younger (64 ± 12 versus 70 ± 10 years, P = 0 ...

      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 ...

    3. Drug-eluting stent implantation in patients with acute coronary syndrome - the Activity of Platelets after Inhibition and Cardiovascular Events: Optical Coherence Tomography (APICE OCT) study

      Drug-eluting stent implantation in patients with acute coronary syndrome - the Activity of Platelets after Inhibition and Cardiovascular Events: Optical Coherence Tomography (APICE OCT) study

      Aims: To our knowledge, no randomised study has compared rates of uncovered stent struts in everolimus (EES) vs. new-generation zotarolimus-eluting (ZES-R) stents in acute coronary syndrome (ACS). The aim of our study was to evaluate the completeness of neointimal coverage with optical coherence tomography (OCT) in ACS patients treated with drug-eluting stents (DES) comparing EES versus new-generation ZES-R. Methods and results: All eligible ACS patients admitted to four Italian centres with a clinical indication for culprit lesion intervention were randomised 1:1 to EES or ZES-R. The primary study endpoint was the percentage of uncovered stent struts evaluated by optical ...

    4. Stent-related defects in patients presenting with stent thrombosis: differences at optical coherence tomography between subacute and late/very late thrombosis in the Mechanism Of Stent Thrombosis (MOST) study

      Stent-related defects in patients presenting with stent thrombosis: differences at optical coherence tomography between subacute and late/very late thrombosis in the Mechanism Of Stent Thrombosis (MOST) study

      Aims: Subacute, late, and very late stent thrombosis (ST) may occur after stent implantation, but they are characterised by different underlying pathophysiological mechanisms. We sought to appraise differences between subacute and late/very late ST at the thrombus site by optical coherence tomography (OCT). The Mechanism Of Stent Thrombosis (MOST) study was a prospective multicentre non-randomised registry which enrolled six subacute ST and six controls (subacute ST study), and 17 late/very late ST and 17 controls (late/very late ST study). Methods and results: Patients with subacute ST had a minimum stent area at the thrombus site of 2 ...

    5. Optical coherence tomography in unprotected left main coronary artery stenting

      Optical coherence tomography in unprotected left main coronary artery stenting
      Aims: Delayed or incomplete stent endothelisation and stent malapposition may predispose to DES thrombosis that can be catastrophic event in the left main coronary artery (LMCA). OCT can accurately identify stents struts and arterial tissue, but is limited by the need of vessel blood clearance and penetration; also no data exists on its use in LMCA. We sought to verify whether optical coherence tomography (OCT) can accurately assess arterial wall response after drug eluting stent (DES) implantation in the LMCA. Conclusions: OCT assessment of vascular response after LMCA DES implantation is safe and feasible. Further development of OCT imaging technology ...
