INTRODUCTION: A common approach to patients, who developed atrial flutter secondary to treatment with class Ic anti-arrhythmic drugs for atrial fibrillation (AF) (Ic flutter), is a hybrid approach: ablation of the Cavo-Tricuspid isthmus (CTI) and continuation Ic medical treatment to prevent recurrence of AF. We aim to explore the clinical outcome of patients treated in this approach. METHODS AND RESULTS: Two hundred and four consecutive patients who underwent ablation for typical AFL at a tertiary medical center between 2010 and 2016 were enrolled and followed up...

BACKGROUND: Atrial fibrillation (AF) is associated with a risk for cognitive impairment and dementia, which is more pronounced in patients with a history of clinical stroke. Observational trials suggest that the implementation and quality of long-term anticoagulation impact dementia risk. Emerging evidence suggests that direct oral anticoagulants may improve long-term risk of dementia in AF patients. METHODS: This manuscript describes the rational and trial design of the the Cognitive Decline and Dementia in Atrial Fibrillation Patients (CAF) Trial...
