Part 1: Access
Learn about different access options guiding catheter choices, catheter hygiene, and pre-CATH medication before performing CMD testing.
Part 2: CMD Testing Set-Up
Learn the steps to prepare for CMD testing, perform a reliable zero, equalize, and measure Resting Full-cycle Ratio (RFR).
Part 3: Procedure Process and Review
Learn how to set up PressureWire™ X Guidewire and CoroFlow‡ Cardiovascular System to take measurements, and analyze results.

Part 6: Understanding the Software
Learn how to check results when the CMD testing is done, how to identify borderline results, and what are some of the check points for an adequate CMD study.
Part 7: Analyzing Testing Results

Part 9: Prognostic Data / CorMicA Trial
Learn about the prognostic CFR data and CorMicA Trial.
- What does a low CFR indicate?
- Why does a low CFR occur?
- How does IMR data link to prognosis?
