      Assessing Computational Fractional Flow Reserve From Optical Coherence Tomography in Patients With Intermediate Coronary Stenosis in the Left Anterior Descending Artery
      Background Intravascular optical coherence tomography (OCT) imaging provides limited information on the functional assessment of coronary stenosis. We evaluated a new approach to OCT imagebased computation modeling, which can be used to estimate the fractional flow reserve (FFR) in patients with intermediate coronary stenosis. Methods and Results Ninety-two patients with intermediate diameter stenosis in the left anterior descending artery underwent both FFR measurement with pressure wires and OCT examination. Using ...

      Association between fractional flow reserve and coronary plaque characteristics assessed by optical coherence tomography
      Background The assessment of fractional flow reserve (FFR) in coronary lesions determines the strategy of percutaneous coronary intervention. However, the association between FFR and characteristics of the underlying coronary plaque has not been sufficiently investigated. Methods A total of 110 coronary lesions in 106 patients were evaluated using both FFR and optical coherence tomography (OCT). Coronary plaques were classified into fibrous, fibrocalcific, or fibroatheroma according to OCT evaluation at the ...

      A 60-year-old woman experienced exertional chest pain. She underwent percutaneous coronary intervention with a drug-eluting stent (Nobori, Terumo Corporation, Tokyo) at the midportion of the left anterior descending artery. In the 3-month follow-up angiography, there was an in-stent restenosis at the midportion of the left anterior descending artery, which was also the site of a previous stent implantation (arrow, Figure 1A). In optical coherence tomography, neointimal hyperplasia proliferation with a ...

      Three-dimensional optical coherence tomographic analysis of eccentric morphology of the jailed side-branch ostium in coronary bifurcation lesions
      Background The severity of angiographic diameter stenosis of the jailed side-branch ostium is usually overestimated over the three-dimensional (3D) optical coherence tomography (OCT)-measured actual stenosis. Using the 3D-OCT, morphologic changes in the jailed side-branch ostium were evaluated before and after a single stent crossover at coronary bifurcation lesions. Methods In 109 patients who received a single stent crossover at coronary bifurcation lesions, the pre- and post-intervention minimal lumen area ...

      Eccentric morphology of jailed side-branch ostium after stent crossover in coronary bifurcation lesions: A three-dimensional optical coherence tomographic analysis
      Background Angiographic stenosis of a jailed side-branch ostium is usually observed after a single-stent crossover at coronary bifurcation lesions. However, the stenosis severity is typically overestimated due to the limited information obtained from two-dimensional morphology by angiography. We evaluated the actual stenosis of jailed side-branch ostium using three-dimensional (3D) optical coherence tomography (OCT). Methods Using 3D reconstructions of OCT data, we analyzed minimal lumen area (MLA) and eccentricity of the ...
