Early recurrence of atrial tachyarrhythmia post –atrial fibrillation ablation: Filling in the blank
Supported by the recent results of the Catheter Ablation vs Antiarrhythmic Drug Therapy for Atrial Fibrillation (CABANA) and Early Treatment of Atrial Fibrillation for Stroke Prevention (EAST-AFNET4) trials, catheter ablation is a preferable contemporary linchpin in the treatment of symptomatic atrial fibrillation (AF).1,2 Traditionally, the efficacy with ablation has been broadly defined by either objective arrhythmic recurrence such as atrial arrhythmias of over 30 seconds in duration or subjective recurrence of symptomatic arrhythmias.

Long-term outcomes and periprocedural safety and efficacy of percutaneous left atrial appendage closure in a UK tertiary centre: 11-year experience
Left atrial appendage occlusion (LAAO) has been widely adopted as a strategy for stroke prevention in patients with atrial fibrillation ineligible for oral anticoagulation.

EP News: Allied Professionals
In this multicenter, randomized trial (Whitlock et al. New Engl J Med. 2021;384:2081-91. PMID: 33999547), the investigators sought do determine whether surgical left atrial appendage occlusion (LAAO) prevents ischemic stroke in patients with atrial fibrillation (AF). Patients with AF and CHA2DS2-VASc score of at least 2 who were scheduled to undergo cardiac surgery were randomized on a 1:1 basis to surgical LAAO or no occlusion. The surgeon and surgical team were informed of the randomization, but teams taking care of the patient post-operatively including during long term follow-up, and who were charged with managing anti...

Letter to the Editor — Clinical Phenotypes in AF Trials
Yang et  al1 conducted a retrospective study of the Atrial Fibrillation Follow-up Investigation of Rhythm Management (AFFIRM) trial. Their findings did not support the first primary Early Treatment of Atrial Fibrillation for Stroke Prevention Trial (EAST-AFNET 4) outcome.2 Clinical phenotypes of atrial fib rillation (AF) should be considered.

Strategies to balance stroke and bleeding risk in patients with atrial fibrillation and cancer
A 76-year-old female with obesity, hypertension, persistent atrial fibrillation, and heart failure with preserved ejection fraction is started on ibrutinib 420 mg once daily for Waldenstrom ’s macroglobulinemia. Due to concern for drug-drug interactions, her amiodarone is decreased from 200 to 100 mg daily, and she is continued on metoprolol succinate 100 mg daily and apixaban 5 mg twice daily. She presents to the clinic one month later with extensive superficial ecchymoses, and her apixaban dose is reduced to 2.5 mg twice daily due to concerns that this may reflect the combined antiplatelet effects of ibrutinib and anti...

EP News: Quality Improvement and Outcomes: Defining and Measuring Atrial Fibrillation Quality Indicators in Canada
In 2016, the Working Group published an initial report identifying and defining priority QIs in 3 distinct categories: access to care, treatment, and outcomes (Can J Cardiol 2016;32:1566, PMID 27297003). An iterative process resulted in the selection of 3 priority QIs: (i) proportion of AF patients at high risk of stroke receiving an oral anticoagulant, (ii) annual rate of stroke, (iii) annual rate of major hemorrhage. A feasibility assessment followed, which determined that none of the QIs as defined could be adequately measured with existing data sources.

Anti-diabetic drugs for preventing atrial fibrillation: a new revolution?
Type 2 diabetes mellitus (DM) and atrial fibrillation (AF) are two of the great epidemics of our time. DM affects and estimated 8.5% of adults in the US1, and is associated with an increased risk of cardiovascular events, including AF.2 AF in turn affects an estimated up to 12.5% of adults over age 65 years in the US, decreases quality of life and increases the risks of heart failure, stroke and death 3,4. In 2015, the EMPA-REG OUTCOME randomized controlled trial (RCT), assessing a sodium glucose co-transporter 2 inhibitor (SGLT-2i), sparked interest in the therapeutic potential for oral anti-diabetic agents to reduce card...

Who is at risk of atrial fibrillation?
Atrial fibrillation (AF) is a common cause of stroke, with prevalence increasing alongside the aging of our population [1]. Increasing age, hypertension, obesity, heart failure, sleep apnea, diabetes, coronary disease, chronic kidney disease and smoking account for much of the global risk of AF [2 3]. Incident AF is also predicted by both rare and common genetic variants, many of which encode for cardiac structural and electrical proteins, as well as by more complex heritable traits such as height, obesity and race [4-6].

Racial Differences in Incidence of Atrial Fibrillation after Cryptogenic Stroke
The incidence of atrial fibrillation (AF) is lower among non-whites compared to whites, despite a higher burden of AF risk factors. The incidence of new AF after cryptogenic stroke among minorities, however, is unknown.
