Clinical Trial 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.

Clinical Trial Description

In coronary angiography, 50% or more stenosis of the causative vessel is observed in a patient with stable angina pectoris (SAP) or 50% or more stenosis of a non-causative vessel is observed in acute coronary syndrome (ACS) Based on 0.90, if it is less than 0.89, PCI is performed, and if it is 0.90 or more, drug treatment is performed. When the pressure wire tests are performed, the pressure wire is inserted from the origin of the blood vessel through the lesion to the distal portion, and the pressure wire is placed at the distal end of the blood vessel for measurement. In this process, there are many cases where the pressure wire escapes the branch blood vessel or does not pass through well. It takes a long time to stand up and evaluate stenosis, and in many cases, an additional contrast medium is used to additionally check blood vessel travel and to check the position and condition of the pressure wire. To overcome this, the software roadmap installed in the cardiac fluoroscopy device of the cardiac catheterization room can be helpful. However, there are currently no studies related to roadmaps in coronary artery examination. Therefore, in this study, we want to evaluate the effectiveness of the roadmap when examining FFR and iFR. ;
