    2. 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 ...

    6. Volumetric assessment of lesion severity with optical coherence tomography: relationship with fractional flow reserve

      Volumetric assessment of lesion severity with optical coherence tomography: relationship with fractional flow reserve

      Aims: Frequency-domain optical coherence tomography (FD-OCT) provides a rapid tomographic scan of a coronary vessel, with an accurate reconstruction of its lumen profile. An FD-OCT-based metric that corresponds more closely with physiological significance of lesions may enable more precise guidance of interventional procedures. The aim of this feasibility study was to evaluate a new method for quantifying coronary lesion severity that estimates hyperaemic flow resistance of branched vessel segments imaged by FD-OCT. Methods and results: An analytical flow model was developed that relates fractional flow reserve (FFR) to the vascular resistance ratio (VRR), a measure of blood flow resistance derived ...

    7. Angiography alone versus angiography plus optical coherence tomography to guide decision-making during percutaneous coronary intervention: the Centro per la Lotta contro l’Infarto-Optimisation of Percutaneous Coronary Intervention (CLI-OPCI) study

      Angiography alone versus angiography plus optical coherence tomography to guide decision-making during percutaneous coronary intervention: the Centro per la Lotta contro l’Infarto-Optimisation of Percutaneous Coronary Intervention (CLI-OPCI) study

      Aims: Angiographic guidance for percutaneous coronary intervention (PCI) has substantial limitations. The superior spatial resolution of optical coherence tomography (OCT) could translate into meaningful clinical benefits. We aimed to compare angiographic guidance alone versus angiographic plus OCT guidance for PCI. Methods and results: Patients undergoing PCI with angiographic plus OCT guidance (OCT group) were compared with matched patients undergoing PCI with angiographic only guidance (Angio group) within 30 days. The primary endpoint was the one-year rate of cardiac death or myocardial infarction (MI). A total of 670 patients were included, 335 in the OCT group and 335 in the Angio ...

    10. Serial Assessment of Coronary Artery Response to Paclitaxel-Eluting Stents Using Optical Coherence Tomography

      Serial Assessment of Coronary Artery Response to Paclitaxel-Eluting Stents Using Optical Coherence Tomography

      Background—The paucity of longitudinal, serial high-resolution imaging studies has limited our understanding of in vivo arterial response to drug-eluting stents. We sought to investigate the human coronary response to paclitaxel-eluting stent implantation, using serial optical coherence tomography assessments. Methods and Results—Thirty patients with at least 2 significant coronary lesions in different vessels were treated with a paclitaxel-eluting stent. The most severe stenosis (lesion A) was treated at the initial procedure, and the second target vessel (lesion B) was stented 3 months later. Optical coherence tomography was performed at baseline, 3-, and 9-month follow-up for lesions A and baseline ...

    11. A Self-Expandable Coronary Stent System to Treat Complex Coronary Stenosis Complicated by Poststenotic Aneurysm: An Optical Coherence Tomographic Evidence-Based Case Report

      A Self-Expandable Coronary Stent System to Treat Complex Coronary Stenosis Complicated by Poststenotic Aneurysm: An Optical Coherence Tomographic Evidence-Based Case Report
      Coronary artery aneurysm is a relatively uncommon disorder characterized by coronary artery dilatation with diameter that exceeds 50% of the normal adjacent segments with atherosclerosis being the most common etiology.1 Aneurysms can be adjacent to a stenosis in a post- or prestenotic location. Both anatomical conditions are technically challenging regarding their percutaneous treatment because of the large discrepancy in size between the stenotic and dilated segments, and require careful choice of the most appropriate technique and device. We have successfully treated a coronary stenosis complicated by a poststenotic aneurysm in a 60-year-old patient with atypical angina using a novel ...

      Ten Years of Severe Vitreomacular Traction Syndrome without Functional Damage Demonstrated by Optical Coherence Tomography
      To describe anatomical and functional features in one patient with 10 years of severe vitreomacular traction syndrome (VTS) without functional damage demonstrated by optical coherence tomography (OCT). Patient and Methods. One patient with a history of 10 years VTS, with best-corrected visual acuity of 20/32, was followed up with OCT. Follow-up examinations, 3months for the first year after diagnosis and every 6 months for the subsequent years, were performed. Results. Follow-up examinations showed no change anatomically and functionally. Far and near visual acuity was unchanged. OCT by Heidelberg Spectralis did not evidence differences from Stratus OCT images. Conclusion. VTS ...

      Optical coherence tomography follow-up of the subintimal tracking and re-entry technique for chronic total occlusion
      A 44-year-old man, a smoker with dyslipidemia, underwent successful percutaneous coronary intervention (PCI) of a chronic total occlusion in the right coronary artery (RCA). The site of occlusion was very proximal. An attemp to cross the leason was performed using an antegrade approach, during which dissection of the ostium occurred and the guidewire entered the false lumen.

      Enhanced Depth Imaging Optical Coherence Tomography of the Choroid in Idiopathic Macular Hole: A Cross-sectional Prospective Study
      Purpose:: To determine the choroidal thickness in the macular area in patients with idiopathic macular hole in one eye and an unaffected fellow eye and in healthy controls.Design:: Cross-sectional, prospective study.Methods:: Twenty-two patients with a full-thickness unilateral idiopathic macular hole and 22 age- and sex-matched controls were recruited. Enhanced depth imaging optical coherence tomography images were obtained by using spectral-domain optical coherence tomography. The choroidal thickness was measured in the subfoveal area and 1000 μm and 2000 μm away from the fovea in the nasal and temporal regions. The diameter of the macular hole and the axial length ...
