入选标准
- •≥18 years of age
- •Scheduled for a coronary angiogram at the Royal Adelaide Hospital.
- •Women must be non-lactating or not of childbearing potential (1 year post menopausal or surgically sterilized [total hysterectomy, bilateral tubal ligation, bilateral oophorectomy]).
- •Target artery must be >2 mm to accommodate the IVUS catheter.
- •IVUS must be clinically indicated or indeterminate angiographic lesion in the artery (40%-70% angiographic stenosis)
排除标准
