Diagnostic Accuracy of Artificial Intelligence-Enhanced Ultrasonic Flow Ratio for On-Site Assessment of Coronary Stenosis (FEATURE Study)

Liu L, Yu L, Ding D, et al. JACC Asia. 2026. doi:10.1016/j.jacasi.2026.04.011

FEATURE前瞻性临床试验证实在介入导管室现场计算的UFR诊断准确率94%、AUC 0.96，显著优于MLA，可常规用于临床

Ultrasonic flow ratio measured immediately after successful rotational atherectomy with stent implantation predicts major adverse cardiovascular events

Zhao T, Jin Q, Zhang X, et al. Front Cardiovasc Med. 2025;12:1418587. doi:10.3389/fcvm.2025.1418587

旋磨+支架术后UFR是12个月MACE的独立预测因子（C-index 0.82），预测性能优于术后μQFR，可作为重度钙化病变预后分层工具

Segmental post-percutaneous coronary intervention physiological gradients using ultrasonic or optical flow ratio: insights from ASET JAPAN study

Revaiah PC, Miyashita K, Tsai TY, et al. Eur Heart J Imaging Methods Pract. 2025;3(1):qyaf017. doi:10.1093/ehjimp/qyaf017

ASET JAPAN研究证实PCI术后节段性UFR/OFR梯度可识别残余缺血并预测不良预后，指导支架优化，实现从解剖满意到功能学满意的升级

Comparative Analysis of Optical Flow Ratio (OFR) Derived From OCT Images and Ultrasonic Flow Ratio Derived From IVUS at Sequential Side Branches Within the Same Segment of the Coronary Vessel

Revaiah P, Bajaj R, Miyashita K, et al. JACC. 2024;84(18_Supplement):B180. doi:10.1016/j.jacc.2024.09.615

OFR与UFR在同一血管连续侧支处功能学一致性良好，UFR凭借IVUS组织穿透优势在钙化等复杂病变的节段性评估中更具潜力
