Comparison of Dabigatran Versus Warfarin Treatment for the Prevention of New Cerebral Lesions in Valvular Atrial Fibrillation
Atrial fibrillation is one of the most common arrhythmias in the United States and is associated with an increased risk of thromboembolic events.1 The American Heart Association/American College of Cardiology/Heart Rhythm Society guidelines recommend oral anticoagulation with either warfarin or oral non-vitamin K antagonists for patients diagnosed with atrial fibrillation with a high risk for ischemic stroke based on the CHA2DS2-VASc score.2 The recently published article “Comparison of Dabigatran Versus Warfarin Treatment for Prevention of New Cerebral Lesions in Valvular Atrial Fibrillation” discussed the efficacy of...

Reply to the Comment on “Comparison of Dabigatran Versus Warfarin Treatment for Prevention of New Cerebral Lesions in Valvular Atrial Fibrillation”
We thank Dr. Abrahim et al for their interest and valuable comment on our study.1 In the methodology section, we intended to recruit stable patients who were able to use the standard anticoagulation in the outpatient setting. Therefore, we excluded the patients with acute stroke within 2  weeks or patients with high-bleeding risk. All the patients received standard rate control therapy according to the relevant guideline.2 The proportion of medications for rate control such as β blocker (56% of overall patients), calcium channel blocker (24%), or digitalis (31%) were already prese nted, and the mean heart rate was 74.1 ± 14.2 beats/min.

An Updated Meta-Analysis on the Clinical Outcomes of Percutaneous Left Atrial Appendage Closure Versus Direct Oral Anticoagulation in Patients With Atrial Fibrillation
The availability of direct oral anticoagulants (DOACs) with known lower bleeding risk compared with warfarin have raised questions about the role of left atrial appendage closure (LAAC). We aimed to perform a meta-analysis to compare the clinical outcomes for LAAC versus DOACs. All studies directly comparing LAAC with DOACs up to January 2023 were included. The outcomes studied included the combined major adverse cardiovascular (CV) events outcomes, ischemic stroke and thromboembolic events, major bleeding, CV mortality, and all-cause mortality.

Direct Oral Anticoagulants: Patients Benefit When Prescribers Get the Message
Direct oral anticoagulants (DOACs) have demonstrated similar or better efficacy to warfarin in reducing stroke and systemic embolic events in large-scale prospective trials.1 –4 In addition, these trials demonstrated either noninferiority or superiority in reducing bleeding events compared with warfarin. To treat high-risk patients with atrial fibrillation (AF) and avoid bleeding in low-risk patients, current guidelines recommend oral anticoagulants in high-risk patien ts with AF with CHA2DS2VASc scores of ≥2 in men and ≥3 in women.
