      Overaggressive stent expansion without intravascular imaging: impact on restenosis

      Objective Aggressive stent expansion is required for optimal strut apposition, but risk of stent deformation, fracture and subsequent restenosis is potentially greater when performed without intravascular imaging guidance. We investigated how frequently stents are ‘overexpanded’ and whether this correlates with restenosis. Design and setting Single-centre prospective database study at a high-volume tertiary university hospital. Patients 243 patients undergoing single-vessel stenting for de novo stenosis in 277 lesions. Exclusion criteria were bifurcational, graft or left main disease and intravascular imaging use. All had ischaemia-driven repeat coronary angiography up to 48 months later. Degree of stent overexpansion was the difference between nominal ...

    2. The invasive assessment of coronary atherosclerosis and stents using optical coherence tomography: a clinical update

      The invasive assessment of coronary atherosclerosis and stents using optical coherence tomography: a clinical update

      Ischaemic heart disease (IHD) remains one of the leading causes of death. Atherosclerosis has been intensely researched given the IHD prevalence and the financial impacts on healthcare systems. More recently, in vivo characterisation of coronary atherosclerotic plaque and tissue responses following stent implantation in a coronary artery has been made possible by a novel technology called optical coherence tomography (OCT). OCT is a light-based, invasive, intracoronary imaging modality long applied to the field of ophthalmology and now in clinical use worldwide. It gives a unique view of within the coronary artery using near-infrared light with a resolution of 15 microns ...

    3. Percutaneous coronary intervention guided by the combination of computed tomographic angiography and optical coherence tomography

      Percutaneous coronary intervention guided by the combination of computed tomographic angiography and optical coherence tomography
      A 70-year-old man, who was a current smoker with dyslipidaemia and hypertension, felt worsening exertional chest oppression and visited our hospital. Electrocardiogram showed a negative T wave in II, III and aVF leads, and transthoracic echocardiography showed a wall motion abnormality at the inferior wall. No elevation of cardiac enzyme was confirmed.
