Table 2 CRF for assessment of epicardial coronary artery stenosis
• Functional assessment of intermediate stenosis (40–70%) |
|---|
• Detection of critical stenosis (>90%) |
• Combined assessment of coronary flow and wall motion |
• Monitoring the changes of CFR in the early, post-PTCA period to detect artery occlusion, microvascular stunning |
• Serial CFR examination after PTCA to predict restenosis |
• Postinfarction coronary flow reserve assessment |
• Assessment of coronary graft patency |
