Brief Summary:
Coronary artery bypass graftingCABG is the golden standard for severe coronary artery diseaseCAD the current surgery strategy is mainly based on coronary angiographyCAG but many trials of PCI have shown that visually stenosis in CAG may not have functional significance The aim of this study is to investigate if the Quantitative Flow Ratio QFR can be adopted in CABG and achieve a better graft patency
Detailed Description:
CABG is the major treatment of three vessels or left main disease CAG is the main basis on choosing the vessels to graft however some of the grafts occluded shortly after surgery due to competitive flow these vessels may not be significantly stenosis in functional assessment such as Fractional Flow Reserve FFR Quantitative Flow Ratio QFR is a novel method for evaluating the functional significance of coronary stenosis Comparing to FFR there is no need for pressure wire or ATP when performing QFR This study plan to investigate the clinical effect of QFR in CABG all patients included will be allocated 11 into two groups QFR-guided and Angio-guided QFR-guided group will be performed a CABG based on the result of QFR the other group will be based on heart team discussion of CAG CTA will be adopted to evaluate the 1 year graft patency
