2022年11月3日 · In addition, the recently published iOPEN‐ISR (Impact of Intravascular Ultrasound on Outcomes Following Percutaneous Coronary Intervention for In‐Stent Restenosis) registry was the first that demonstrated a prognostic benefit of the use of IVUS in guiding revascularization of lesions with ISR.

2011年11月1日 · We assessed the optimal intravascular ultrasound (IVUS) stent area to predict angiographic in-stent restenosis (ISR) after sirolimus-eluting stent implantation for unprotected left main coronary artery (LM) disease.

2021年10月1日 · Intravascular ultrasound (IVUS)-guided stent implantation is associated with a reduction in adverse events after PCI, but its impact on treatment of ISR is not clear. Methods: All patients with 1-year follow-up after ISR treatment from 2003 through 2016 were included and stratified by IVUS use.

Intravascular imaging with intravascular ultrasound (IVUS) or optical coherence tomography (OCT) allows this systematic investigation, to tailor interventions and tackle the underlying mechanism and to optimize the results of any necessary repeated interventions.

Universal and easily applicable IVUS criteria for optimization of stent implantation as well as randomized studies on IVUS-guided DES implantation are necessary to minimize stent malapposition and underexpansion, which in turn can positively influence the rates of stent restenosis and thrombosis.

IVUS was the first available intravascular imaging modality and, over the past 20 years, has demonstrated its ability to help reduce future ischemic events [24,25]. IVUS allows for vessel size and stent underexpansion identification by defining the external elastic lamina behind the stent struts, even in the presence of lipid plaque .

Methods: In 175 patients with ISR of a single coronary artery (angiographic stenosis >50%), we compared quantitative coronary angiography and intravascular ultrasound (IVUS) with stress myocardial single-photon emission computed tomography (SPECT). A positive SPECT was a reversible perfusion defect in the territory of the ISR artery.

thrombosis (ST) and in-stent restenosis (ISR) down the line. In this chapter, we discuss the indications for IVUS, various types of IVUS catheters, and procedural technique including challenges.

2021年10月1日 · Intravascular ultrasound (IVUS)-guided stent implantation is associated with a reduction in adverse events after PCI, but its impact on treatment of ISR is not clear. All patients with 1-year follow-up after ISR treatment from 2003 …

2023年12月12日 · 通过联合应用血管内超声 (IVUS)+光学相关断层成像扫描 (OCT)二合一腔内影像技术，高效地提供了精准、全面的腔内影像信息。 这也是远大医药 (0512.HK)血管腔内影像设备NOVASIGHT的首例临床应用。 NOVASIGHT™ HYBRID SYSTEM这款创新性IVUS+OCT双模成像系统 (设备+导管)于今年获国家药品监督管理局 (NMPA)批准上市，也是目前唯一获得了美国FDA上市批准的IVUS+OCT双模成像系统，在美国和加拿大均已开展临床应用。 ISR最小管腔 …
