    1. A serial three- and nine-year optical coherence tomography evaluation of neoatherosclerosis progression after sirolimus- and paclitaxel-eluting stents implantation

      A serial three- and nine-year optical coherence tomography evaluation of neoatherosclerosis progression after sirolimus- and paclitaxel-eluting stents implantation

      Background: Early-generation drug-eluting stents (DES) have been shown to accelerate neoatherogenesis. Limited optical coherence tomography (OCT) data on the very long-term neoatherosclerosis progression after DES implantation are available. Aim: The aim of this study was a serial OCT evaluation of neoatherosclerosis at 3 and 9 years after implantation of sirolimus-eluting stents (SES) and paclitaxel-eluting stents (PES). Methods: Consecutive patients undergoing elective PCI with SES (Cypher, Cordis) or PES (Taxus, Boston Scientific) were included in this single-centre, longitudinal study. OCT analysis was performed after 3 and 9 years by the independent core laboratory. Results: A total of 39 OCT recordings were ...

    2. Bioresorbable vascular scaffolds for a long diffuse coronary lesion: insights from optical coherence tomography at 25-month follow-up

      Bioresorbable vascular scaffolds for a long diffuse coronary lesion: insights from optical coherence tomography at 25-month follow-up

      A 57-year-old man with crescendo angina had a long segment of diffuse lesion in the left anterior descending artery (LAD) (Fig. 1A). Surgical revascularisation was precluded due to poor distal targets, so the patient underwent percutaneous coronary intervention. Overlapping drug eluting stents (DESs) would have resulted in a full metal jacket, which poses long-term risk of stent thrombosis and restenosis, which are often difficult to treat. Considering these issues, we used three overlapping bioresorbable vascular scaffolds (BVS) following adequate lesion preparation (Fig. 1B–D). At the LAD/first-diagonal (D1) bifurcation we used a short DES that overlapped the BVS to ...

    3. Optical coherence tomography imaging during endovascular treatment of a patient with Takayasu arteritis

      Optical coherence tomography imaging during endovascular treatment of a patient with Takayasu arteritis

      Takayasu disease (TA) is an inflammation of the large arteries arising from the aortic arch, and sometimes the abdominal aorta. The basis for the treatment of TA is systemic therapy together with symptomatic treatment involving operational or endovascular treatment. Indications are interpolated from recommendations on treatment of atherosclerosis. However, these recommendations should be approached with caution. Thus, the use of modern methods to diagnose and monitor treatment of these changes are of particular interest. Optical coherence tomography (OCT) allows detailed analysis of the inner layers of the wall and atherosclerotic plaque, and it has been performed safely for acute coronary ...

    4. Ruptured plaque in the renal artery by optical coherence tomography

      Ruptured plaque in the renal artery by optical coherence tomography

      Coronary plaque rupture (PR) may be the trigger for platelet accumulation, subsequent thrombus formation, and acute coronary syndrome (ACS). Case series have suggested that conservative treatment of no-flow limiting coronary lesions with the feature of PR is relatively safe. Little is known about PR in the renal arteries. We present a case of PR in the renal artery confirmed by optical coherence tomography (OCT). A 67-year-old male patient with chronic kidney disease stage 3, arterial hypertension, and diffuse atherosclerosis was referred for renal arteriography. Having been treated with four antihypertensive drugs, the patient’s blood pressure (BP) was suboptimal. The ...

    5. Optical coherence tomography: guided primary percutaneous coronary intervention in acute myocardial infarction. A bridge too far?

      Optical coherence tomography: guided primary percutaneous coronary intervention in acute myocardial infarction. A bridge too far?

      Primary percutaneous coronary intervention (PCI) is associated with a certain risk of post-procedural ischemic complications. Therefore, stent implantation technique in the acute myocardial infarction settings should be optimal to improve short- and long-term clinical outcomes. Optical coherence tomography (OCT) is a light-based imaging modality with an excellent resolution that enables in vivo visualization of the coronary artery structures reported only by the pathohistological studies. Consequently, OCT should help the operator in decision-making throughout the whole primary PCI procedure. OCT seems particularly useful in evaluating culprit lesions, assessing thrombus burden, selecting a proper stent type and size, optimizing the post-implantation result ...

    6. Optical coherence tomography to reveal vascular lesions after catheter-based renal nerve ablation with a novel multi-electrode EnligHTNTM system

      Optical coherence tomography to reveal vascular lesions after catheter-based renal nerve ablation with a novel multi-electrode EnligHTNTM system

      A 72-year-old female with a history of sleep apnoea syndrome was referred to the Andreas Gruentzig Catheterisation Laboratories for catheter-based renal nerve ablation (RNA) due to drug-resistant, uncontrolled hypertension. After intravenously loading with aspirin, the RNA was obtained using the first generation multi-electrode EnligHTNTM system (St. Jude Medical, Westford, MA, USA) delivering 8 ablation runs on both the left and the right renal artery. Before and after the RNA procedure, optical coherence tomography (OCT) was performed using the C7-XR imaging system (LightLab Imaging, Inc., Westford, MA, USA) with a non-occlusive technique and a single-mode optical fibre catheter (frequency domain-OCT-catheter, DragonFlyTM ...

    7. Evaluation of aneurysm after coronary stent implantation by optical coherence tomography

      Evaluation of aneurysm after coronary stent implantation by optical coherence tomography

      A 47 year-old man with dyslipidaemia was admitted with acute ST-elevation myocardial infarction of the inferior wall with total occlusion of the right coronary artery (RCA). After the administration of medical treatment, thrombus aspiration was applied to the vessel and a 3.0 × 28 mm bare stent was deployed to the RCA at 18 atm. After the intervention (PCI), coronary angiography (CAG) revealed TIMI flow 3 (Figs. 1A, C). The patient’s clinical status had improved. Six months later, he was admitted to our hospital complaining of atypical chest pain. After an abnormal exercise treadmill stress test, we performed control ...
