Trends, indications and outcomes of cardiac implantable device system extraction: a single UK centre experience over the last decade. (A) A comparison of the total number of cases performed, evolving extraction indications and the overall use of laser in the last decade is depicted herein. (B) shows the trends in individual extracted lead type over the last decade. Both ICD and CS lead extractions have seen a considerable rise during this period.

Novel System for Real-Time Integration of 3-D Echocardiography and Fluoroscopy for Image-Guided Cardiac Interventions: Preclinical Validation and Clinical Feasibility Evaluation Clinical study to document feasibility in an AF ablation case. Real-time hybrid views were generated during the trans-septal puncture and subsequent placement of circular mapping and ablation catheters within the left atrial chamber.

Radial Versus Femoral Access Is Associated With Reduced Complications and Mortality in Patients With Non–ST-Segment Kaplan–Meier curves for mortality at 30 days and 1 year. Kaplan–Meier curves for (A) unmatched and (B) propensity-matched cohorts. Survival curves were compared using log-rank tests. For the propensity-matched cohorts, a stratified log-rank test was used, where the groups were stratified by quintiles of propensity scores. CI indicates confidence interval; and HR, hazard ratio.
