Ultrasound, IVUS) imaging technique in the new coronary artery of one kind that occurs afterwards, compared with IVUS, OCT high resolution ratio
Make it in evaluation vulnerable plaque, instruct stenter to implant, especially in acute coronary syndrome (Acute Coronary
Syndrome, ACS) in diagnosis and treatment using of increasing concern.
2011, to IVUS in American Society of Cardiology/American Heart Association (ACCF/AHA) Percutantnoeus coronary intervention guide
The recommendation etc. applied in percutaneous coronary intervention (pci) (Percutaneous Coronary Intervention, PCI)
Grade is IIa, and to the recommendation grade of OCT because evidence-based medical deficiency is not yet established.2012, CLI-OPCI studies have shown that
Compared with the PCI treatment of simple radiography guidance, the PCI treatment under OCT guidance can significantly improve patient's prognosis.Then, 2013
Year European Society of Cardiology is about in Stable coronary heart disease administration guide, and OCT is for assessment lesion characteristics and optimization stenter to implant
Process is classified as IIb grades of recommendations (level of evidence is B grades), and overall evidence level is equal to IVUS.2014, heart of Europe disease
In the myocardium revascularization guide of meeting/Europe cardiothoracic surgery association (ESC/EACTS), recommendation grade of the OCT to optimization PCI is promoted
Recommend to the IIa grade being equal with IVUS.The ILUMIEN I that delivers for 2015 is research shows that PCI is preoperative and/or postoperative row OCT inspection
Look into the strategies of interventional treatment that can influence patient.ILUMIEN II result of study shows that OCT is not inferior in terms of instructing stent expansion
IVUS.With the continuous renewal of OCT technology and the announcement of more perspective study data, OCT is led in coronary intervention
Status in domain will further be promoted.
