TCT-27 What is the Most Effective Treatment After Rotational Atherectomy for Stent Underexpansion? An Inverse Probability of Treatment Weighting Analysis Based on Propensity Score

Propensity scores were created using logistic regression models to adjust potential confounding factors and the inverse probability of treatment weighting (IPTW) method was used to evaluate differences intarget lesion revascularization(TLR) between the treatment groups in this study. Multivariate analyses using logistic regression adjusted by propensity scores, in which diffuse ISR was the independent predictor between BA vs.
