      Potential Benefit of Final Kissing Balloon Inflation After Single Stenting for the Treatment of Bifurcation Lesions – Insights From Optical Coherence Tomography Observation
      Background: Treatment of coronary bifurcation lesions using a single stenting strategy is preferable over that using a 2-stent technique. The benefit of final kissing inflation (FKI), however, has not been established. Methods and Results: Seventy-two patients (76 lesions) with true bifurcation lesions treated with a single drug-eluting stent with FKI (n=33 lesions) or without FKI (non-FKI, n=43 lesions) were enrolled in this study. Optical coherence tomography (OCT) was ...

      Qualitative and Quantitative Assessment of Stent Restenosis by Optical Coherence Tomography
      We hypothesized that the tissue components of in-stent restenosis (ISR) might differ between drug-eluting stents (DES) and bare-metal stents (BMS) and that these differences could be distinguished by qualitative and quantitative optical coherence tomography (OCT) analyses. Methods and Results: One-hundred and twenty-two initial ISR lesions (sirolimus-eluting stents: n=28; paclitaxel-eluting stents: n=51; BMS: n=43) were evaluated with OCT. Based on their OCT appearance, the lesions were classified as ...

      Effect of Cytochrome P450 2C19 Polymorphism on Target Lesion Outcome After Drug-Eluting Stent Implantation in Japanese Patients Receiving Clopidogrel
      Background:Cytochrome P450 (CYP) 2C19 polymorphism is associated with reduced responsiveness to clopidogrel and poor clinical outcome after drug-eluting stent (DES) implantation, but its contribution to lesion outcome after DES implantation is unclear. Methods and Results:The study included 160 Japanese patients who received clopidogrel and underwent DES implantation with follow-up angiography. Patients were divided into 3 groups by CYP2C19 polymorphism: extensive metabolizers (EM), intermediate metabolizers (IM), and poor metabolizers ...

    5. Comparison by Optical Coherence Tomography of Paclitaxel-Eluting Stents With Sirolimus-Eluting Stents Implanted in One Coronary Artery in One Procedure: 6-Month Follow-up

      Comparison by Optical Coherence Tomography of Paclitaxel-Eluting Stents With Sirolimus-Eluting Stents Implanted in One Coronary Artery in One Procedure: 6-Month Follow-up
      Differences between paclitaxel-eluting stents (PES) and sirolimus-eluting stent (SES) in neointimal proliferation under strictly matched conditions remain to be clarified by optical coherence tomography (OCT). Methods and Results: Between May and December 2007, 27 patients were implanted with a PES and a SES, randomized to either the proximal or distal site in a single coronary artery, and underwent follow-up angiography and OCT examination at 6 months. The frequency of vessel ...

      Factors That Influence Measurements and Accurate Evaluation of Stent Apposition by Optical Coherence Tomography
      kground: Factors influencing measurements and accurate evaluation of stent apposition by optical coherence tomography (OCT) are not established. Methods and Results: Phantom models of known luminal sizes and lengths were evaluated by OCT under various conditions and measurements were compared with actual values. Stents implanted into phantom models were examined by OCT to validate the measurement point on the stent strut surface for accurate evaluation of stent apposition. Strut thickness ...
