COVID-19 studies are our top priority.

For new and updated trial submissions, we are processing trials as quickly as possible and appreciate your patience. We recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Key inclusion criteria
- Subject must be at least 18 years of age

- Subject (or legal guardian) understands the study requirements and the treatment
procedures and provides written informed consent before any study-specific tests or
procedures are performed

- Subject is eligible for percutaneous coronary intervention (PCI) and is an acceptable
candidate for coronary artery bypass grafting (CABG)

- Subject has either:

Symptomatic coronary artery disease with one of the following: stenosis > 70%, abnormal
fractional flow reserve (FFR), abnormal stress or imaging stress test, or elevated
biomarkers prior to the procedure or Documented silent ischemia based on one of the
following: abnormal fractional flow reserve (FFR), abnormal stress or imaging stress test,
or elevated biomarkers prior to the procedure

- Subject is willing to comply with all protocol-required follow-up evaluation

- Target lesion must be <12 mm in length with reference vessel diameter >2.75 mm and
<3.25 mm

- Target lesion must have visually estimated stenosis >50% and <100% with thrombolysis
in Myocardial Infarction (TIMI) flow >1
