Impact of Dynamic CoROnary RoADmap System for Guidance of Instantaneous Wave-Free Ratio or Fractional Flow Reserve
Trial Parameters
Brief Summary
In patients with 50-90% stenosis of the coronary artery, the coronary roadmap (dynamic roadmap) is performed when the conventional fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are performed. coronary roadmap system) to confirm the effectiveness of the function.
