7 years, and women constituted 30% of the cohort. The rate of major bleeding complications in the entire cohort was 1.8%. The sensitivity and specificity of the AIBR model were 77.3% and 80.9%, respectively. The ROC-AUC for the AI-BR model (0.873) was superior vs the ACC-BR model (0.764; P=.02) in predicting major bleeding for the test cohort. CONCLUSION The AI-BR model accurately predicts bleeding post PCI and outperforms the ACC-BR model in predicting the risk of bleeding in patients undergoing PCI.BACKGROUND There is paucity of data regarding the temporal trends and outcomes of coronary atherectomy in the United States. METHODS We queried the National Inpatient Sample database (2011-2016) for hospitalizations of patients undergoing coronary atherectomy procedures. We also compared outcomes of non-orbital vs orbital coronary atherectomy in a more contemporary cohort. RESULTS Our analysis included 2,990,223 hospitalizations with PCI, of which 114,462 (3.8%) included an atherectomy procedure. A significant increase in coronary atherectomy procedures was observed over time (0.66% in 2011 vs 8.9% in 2016; Ptrend=.04). There was an increase in in-hospital mortality associated with atherectomy procedures from 3.2% in 2011 to 4.7% in 2016 (Ptrend=.04), which paralleled the increase in patient comorbidities, use of mechanical circulatory devices (Ptrend less then .001), and procedural complications. While several predictors of increased mortality after an atherectomy procedure were identified, the use of intravascular ultrasound (IVUS) was associated with lower mortality during atherectomy procedures (adjusted odds ratio [OR] = 0.61; 95% confidence interval [CI], 0.42-0.89), although its overall use was low (10.4%). Compared with other atherectomy procedures, orbital atherectomy was associated with lower in-hospital mortality (3.2% vs 4.7%; adjusted OR = 0.50; 95% CI, 0.30-0.81). CONCLUSION Our large national database analysis demonstrates an increase in the number of coronary atherectomy procedures and in their in-hospital mortality and complications over time. SKI II Orbital atherectomy appears to be associated with favorable outcomes compared with non-orbital atherectomy, and IVUS use was associated with lower mortality during atherectomy procedures. These associations do not necessarily imply causality and need to be confirmed in future randomized clinical trials.OBJECTIVES Endovascular therapy (EVT) has emerged as an alternative to surgery for the treatment of symptomatic infrarenal aortic stenosis (IAS). However, long-term outcomes with EVT are unknown. METHODS We performed a retrospective review of patients with IAS treated with the endovascular approach at the University of Toledo Medical Center, Toledo, Ohio. We compared our single-center study (SCS) with a review of published studies (ROS) regarding complications, patency rate (PR), and repeat intervention rate (RIR). Pearson's Chi-square or Fisher's exact test, and the Student's t-test or Mann-Whitney U-test, were used for categorical and continuous variables, respectively. For the ROS data, we used a pooled mean of means. RESULTS A total of 25 patients from the SCS were compared with 698 patients from the ROS data. Mean age was 63 years vs 58 years, females comprised 48% vs 54%, Rutherford class 3 comprised 68% vs 69%, and mean follow-up duration was 67 months vs 44 months in SCS vs ROS, respectively. PR at 12 months was 96% vs 90%, while PR at maximum time-period was 92% vs 76% in SCS vs ROS, respectively. RIR in SCS was 4% at 12 months and 8% at the maximum time period (20.2 years). RIR in ROS was 24% at the maximum time period (10 years). The mortality rate was 0% in the SCS arm vs 3.4% in the ROS arm. CONCLUSION EVT is highly effective and safe, and was associated with excellent patency rates at long-term follow-up.OBJECTIVES Instantaneous wave-free ratio (iFR) has been proven to correlate with coronary flow reserve better than fractional flow reserve (FFR) and i
