Emerging Evidence in Left Atrial Appendage Occlusion vs. Oral Anticoagulation Therapy with NOAC
Transcatheter left atrial appendage occlusion (LAAO) is proven non-inferior to warfarin in atrial fibrillation (AF). However, novel oral anticoagulation (NOAC) is now preferred over warfarin as thromboprophylaxis in AF. This study sought to investigate clinical outcome and prognosis in patients with AF treated with either LAAO or NOAC.
Based on the global prospective Amulet Observational Registry (n=1,088), the faculty performed a follow-up study using propensity score 1:2 matching with replacement. A group of 18,570 patients with incident AF and treatment with NOAC (time period 2013-2015) was identified through the Danish National Patient Registry and the Danish National Prescription Registry.
The primary outcome was a composite of ischemic stroke, systemic embolism, major bleeding and all-cause mortality. Secondary outcomes were the individual endpoints of ischemic stroke, major bleeding and all-cause mortality. Both cohorts included the analysis for 2 years of follow-up.
Here, the study author and panelists discuss the findings and wider implications for clinical practice in further detail.

Dr Vivek Y. Reddy is Director of Cardiac Arrhythmia Services for The Mount Sinai Hospital and Director of Electrophysiology for the Mount Sinai Health System, and The Leona M. and Harry B. Helmsley Charitable Trust Professor of Medicine in Cardiac Electrophysiology at the Icahn School of Medicine at Mount Sinai.
Dr Reddy is one of the US's premier cardiac electrophysiologists. He leads a team of physician-scientists who are developing and testing advanced therapies for cardiac arrhythmias and heart failure, including catheter ablation for atrial fibrillation and ventricular tachycardia, and device therapies for stroke prevention. Under his leadership, Mount Sinai is the lead investigational site for many multinational clinical trials exploring new arrhythmia procedures and technologies, most recently pulsed field ablation to treat atrial fibrillation. Moreover, in 2014, he implanted the world’s first miniature leadless pacemaker, as well as the first leadless pacemaker in the United States at The Mount Sinai Hospital.
