| Abstract | branches with >50% stenosis, 19 (28.4%) had FFR≤0.80 and among 163 side branches with ≤50% stenosis, 22 (13.5%) had FFR≤0.80 after stent implantation in main vessels. Using receiver-operating characteristic curve, the optimal cutoff value of diameter stenosis of side branch was 54.9% and area under the curve was 0.64 (95% CI 0.580.71, p<0.001) with a 41.5% sensitivity, an 83.1% specificity, a 34.7% positive predictive value, an 86.3% negative predictive value and a 75.7% accuracy. Multivariate binary logistic regression analysis identified diameter stenosis (odds ratio [OR] 1.04, 95% CI 1.02-1.06, p=0.001) and reference vessel diameter (OR 0.28, 95% CI 0.10-0.77, p=0.014) of side branch before stent implantation as independent predictors of the side branches with FFR ≤0.80 after stent implantation. Conclusion: Most side branch lesions do not have functional significance after stent implantation in the main vessel and quantitative coronary angiography is unreliable in assessing the functional severity of these lesions. |
