简要总结
Collection of coronary images with a hybrid IVUS OCT system.
详细描述
A prospective observational imaging study in patients undergoing coronary angiography and intravascular imaging for either diagnostic purposes or for PCI following a presentation with either stable angina or an acute coronary syndrome.

入选标准
- •Patient is at least 18 years old.
- •Patients arriving for coronary angiography or possible PCI with stable angina or acute coronary syndrome (including unstable angina, NSTEMI or STEMI).
- •Patients with STEMI may be undergoing subsequent staged PCI to additional coronary stenoses after the index STEMI event has been successful treated with primary PCI.
- •Vascular access of at least 6F.
- •Patient provides informed, written consent for participation in the study.
- •A target lesion is present in a suitable artery for intravascular imaging.
排除标准
- •Angiographic evidence of severe calcification
- •Marked tortuosity that precludes imaging of a target coronary artery.
- •GFR (Glomerular filtration rate) <35 mL/min.
- •Patients in cardiogenic shock.
- •Women of child bearing potential, in whom pregnancy cannot be excluded.
- •Patients of age < 18 years old.
- •Patients with an allergy to contrast.
- •Patients unable to grant informed, written consent for participation in the study.
结局指标
主要结局
Collection of the first human coronary images with the hybrid IVUS OCT technology
时间窗: Clinical Report Forms (capturing image analysis) will be completed for each case no later then 72 hours after the procedure.
The hybrid IVUS OCT system permits simultaneous and co-registered acquisition of IVUS and OCT coronary images. IVUS and/or OCT series can be recorded up to 10 cm of the vessel length or up to 20 s of imaging. The physician will review 10 frames and evaluate independently IVUS images, OCT images and the combined IVUS-OCT images for the ability to identify and characterize coronary lesion categories: lipid plaque, calcified plaque, fibrous plaque, thin fibrous cap, positive remodelling and plaque burden. Results, for each frame and imaging modality, of lesion assessment will be tabulated as: a) non-assessable, b) assessable and present, c) assessable and absent. The Clinical Report Form captures tabulated sections for each imaging modality and specific frame selected for lesion evaluation. Results will be presented qualitatively and quantitative as categorical calculations. Image interpretation will be performed independently and blinded to clinical and angiographic information.
