    5. Efficacy of optical frequency-domain imaging in detecting peripheral artery disease: a single-center open-label, single-arm study protocol

      Efficacy of optical frequency-domain imaging in detecting peripheral artery disease: a single-center open-label, single-arm study protocol
      Intravascular optical coherence tomography is a high-resolution intracoronary imaging modality, providing a microscopic image of intravascular features. However, it has lower penetration depth than intravascular ultrasound. Recently, a second-generation optical frequency-domain imaging (OFDI) technique has been developed to provide greater penetration depth and faster pullback speed. However, there is little evidence supporting the efficacy of OFDI in patients with peripheral artery disease (PAD) undergoing endovascular treatment (EVT). We aimed to ...

    13. Comparison between Optical COherence tomography guidance and Angiography guidance in percutaneous coronary intervention (COCOA): Study protocol for a randomized controlled trial

      Comparison between Optical COherence tomography guidance and Angiography guidance in percutaneous coronary intervention (COCOA): Study protocol for a randomized controlled trial
      Background Optical coherence tomography (OCT) is increasingly used as an adjunct to coronary angiography for guiding percutaneous coronary intervention (PCI). The current consensus on PCI is that the large final stent area offers the best chance of a good late clinical outcome. Since OCT provides more accurate information about the coronary artery and implanted stents, OCT-guided stent implantation is expected to achieve greater stent expansion than angiography guidance alone. Therefore ...

    15. Early vascular responses to everolimus-eluting cobalt–chromium stent in the culprit lesions of st-elevation myocardial infarction: results from a multicenter prospective optical coherence tomography study (MECHANISM-AMI 2-week follow-up study)

      Early vascular responses to everolimus-eluting cobalt–chromium stent in the culprit lesions of st-elevation myocardial infarction: results from a multicenter prospective optical coherence tomography study (MECHANISM-AMI 2-week follow-up study)
      The use of cobaltchromium everolimus-eluting stents (CoCr-EES) for ST-segment elevation myocardial infarction (STEMI) reduces the incidence of stent thrombosis compared with bare metal stents, and a substantial difference is apparent in the initial 2 weeks. However, vascular behavior during this early period remains unclear. This was a prospective study (MECHANISM-AMI-2W) to investigate early vascular responses in STEMI patients immediately after CoCr-EES implantation and at 2-week follow-up using frequency domain-optical coherence ...
