      Response to Letter Regarding Article, "Impact of Frequency-Domain Optical Coherence Tomography Guidance for Optimal Coronary Stent Implantation in Comparison With Intravascular Ultrasound Guidance"

      We appreciate the valuable comments by Garcia-Garcia et al regarding our article.1 We agree with the comments on our limitations about study design especially with regard to criteria of the procedure. First, the efficacy of distal protection devices in native coronary arteries is still controversial, and criteria regarding usage of this device are not defined yet. However, we believe this device could be helpful for prevention of distal embolus in certain cases as we have sometimes experienced, and optical frequency-domain imaging (OFDI) is helpful to predict such cases. Making use of the criteria of this study, distal protection was ...

    2. Impact of Frequency-Domain Optical Coherence Tomography Guidance for Optimal Coronary Stent Implantation in Comparison With Intravascular Ultrasound Guidance

      Impact of Frequency-Domain Optical Coherence Tomography Guidance for Optimal Coronary Stent Implantation in Comparison With Intravascular Ultrasound Guidance

      Background—Frequency-domain optical coherence tomography (FD-OCT) is a novel, high resolution intravascular imaging modality. Intravascular ultrasound (IVUS) is a widely used conventional imaging modality for achieving optimal stent deployment. The aim of this study was to evaluate the impact of FD-OCT guidance for coronary stent implantation compared with IVUS guidance. Methods and Results—A total of 70 patients with de novo coronary artery lesions and either unstable or stable angina pectoris were enrolled in this randomized study (optical coherence tomography [OCT] group: n=35, IVUS group: n=35). In the OCT group, stent implantation was performed under FD-OCT guidance alone ...

    3. The impact of epicardial fat volume on coronary plaque vulnerability: insight from optical coherence tomography analysis

      The impact of epicardial fat volume on coronary plaque vulnerability: insight from optical coherence tomography analysis

      Aims Epicardial fat volume (EFV) has been implicated in coronary artery disease. Relationship between EFV and coronary plaque vulnerability has not been elucidated. The aim of this study was to investigate the association of EFV with coronary plaque vulnerability by using optical coherence tomography (OCT). Methods and results We enrolled 117 patients who underwent multislice computed tomography (MSCT) and OCT. EFV was quantified on MSCT. Patients were categorized according to tertiles of EFV: low tertile, EFV 3 ; mid-tertile, 104.1 cm 3 ≤ EFV ≤ 130.7 cm 3 ; high tertile, EFV > 130.7 cm 3 . A total of 180 vessels and ...

    4. Comparative Analysis of Vascular Responses Following Stent Implantation in the Lesion Wth Acute Coronary Syndrome Between Paclitaxel-Eluting and Bare-Metal Stent Using Optical Coherence Tomography

      Background: Safety and feasibility of drug-eluting stent in the lesion with acute coronary syndrome (ACS) is still controversial. Optical coherence tomography (OCT) is a high-resolution intravascular imaging modality, which is expected to visualize microscopic vascular response to coronary intervention. The purpose of this study is to evaluate the difference of vascular responses following stent implantation in the ACS lesions between paclitaxel-eluting stent (PES) and bare-metal stent (BMS) using OCT. Method: Fifty-eight ACS patients who were treated with either PES or BMS (33PESs and 25 BMSs) underwent OCT at 3 months follow-up, and 38 of them (20PESs and 18BMSs) also had ...
