Preventive Drug-coated Balloon Angioplasty in Vulnerable Atherosclerotic Plaque: an OCT-IVUS Imaging Substudy (RESTORE Imaging)
The objective of this imaging substudy of RESTORE trial is to demonstrate the superiority of drug-coated balloon (DCB) treatment on non-flow limited vulnerable plaque as compared to guideline-directed medical therapy (GDMT) in improving plaque stabilization in patients with acute coronary syndrome.
• Subjects must be between 18 and 80 years of age
• Subject must present with acute myocardial infarction or unstable angina planned for PCI
• Successful stent implantation (i.e., residual stenosis less than 20%) must be done in culprit lesions and any lesions with ischemia evidence (e.g., QFR equal or less than 0.8)
• Subject must have at least one native non-culprit lesion with visually estimated stenosis of 40-80% and QFR \>0.8
• Target lesion must have a visually estimated diameter of 2.0-4.0 mm and length of ≤ 50 mm
• Target lesion must have any two of the intravascular imaging criteria of PB \>65%, MLA \<3.5 mm\^2 (OCT) or 4.0mm\^2 (IVUS), FCT \<75 μm, or maximal lipid arc \>180°
• Subject must provide written informed consent before any study-related procedure
