Brief Summary:
This is a prospective, observational, single-center study. The main purpose of this study is to evaluate the diagnostic accuracy of offline computational ultrasonic flow ratio (UFR) in predicting functionally significant three coronary stenosis with conventional pressure wire-based fractional flow reserve (FFR) as the standard reference. The study will be conducted in Fuwai Hospital, and a total of at least 495 patients with all the three coronary vessel diameter stenoses ≥30% are planned to be recruited. Participants who meet the inclusion criteria and do not meet the exclusion criteria will undergo intravascular ultrasound (IVUS) followed by FFR examination. IVUS imaging will be sent to an independent core laboratory for UFR calculation. UFR analyses were performed offline in a blinded fashion without awareness of FFR measurement. Using FFR≤0.80 as the gold standard, the sensitivity and specificity of UFR in the functional significance of all the three coronary artery stenoses will be analyzed.
