The combination of antiarrhythmic agents, amiodarone or dronedarone, with the anticoagulant rivaroxaban is used clinically in the management of atrial fibrillation for rhythm control and secondary stroke prevention respectively. Renal drug-drug interactions (DDIs) between amiodarone or dronedarone and rivaroxaban were previously ascribed to inhibition of rivaroxaban secretion by P-glycoprotein at the apical membrane of renal proximal tubular epithelial cells. Benzbromarone, a known inhibitor of organic anion transporter 3 (OAT3), shares a benzofuran scaffold with amiodarone and dronedarone...

BACKGROUND: The rotational activation created by spiral waves may be a mechanism for atrial fibrillation (AF), yet it is unclear how activation patterns obtained from endocardial baskets are influenced by the 3D geometric curvature of the atrium or 'unfolding' into 2D maps. We develop algorithms that can visualize spiral waves and their tip locations on curved atrial geometries. We use these algorithms to quantify differences in AF maps and spiral tip locations between 3D basket reconstructions, projection onto 3D anatomical shells and unfolded 2D surfaces...

Background - Recurrent paroxysmal atrial fibrillation (PAF) after catheter ablation is presumably caused by failure to achieve durable pulmonary vein isolation (PVI). The primary methods of PVI are radiofrequency (RF) and cryoballoon (CRYO) catheter ablation, but these methods have not been directly compared with respect to PVI durability and the effect thereof on AF burden (% of time in AF). Methods - Accordingly, we performed a randomized trial including 98 patients (68% male, 61 [55-67] years) with PAF assigned 1:1 to PVI by contact-force sensing, irrigated RF catheter or second-generation CRYO catheter...

BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia worldwide. Early diagnosis of AF is crucial for preventing AF-related morbidity, mortality, and economic burden, yet the detection of the disease remains challenging. The 12-lead electrocardiogram (ECG) is the gold standard for the diagnosis of AF. Because of technological advances, ambulatory devices may serve as convenient screening tools for AF. OBJECTIVE: The objective of this review was to investigate the diagnostic accuracy of 2 relatively new technologies used in ambulatory devices, non-12-lead ECG and photoplethysmography (PPG), in detecting AF...

59-year-old women with permanent atrial fibrillation and previous haemorrhagic stroke was admitted for percutaneous left atrial appendage occlusion. Shortly after, AmplatzerTM device migration into the left ventricular outflow tract was confirmed. Unsuccessful transcatheter mobilization led to an emergent surgery for device retrieval and LAA closure. No events at 6-month follow-up.

Introduction: Hypertension (HT) and atrial fibrillation (AF) often coexist. However, the causality between these two conditions remains to be determined. Methods: We used individual participant data from the Atherosclerosis Risk in Communities (ARIC) prospective cohort with 9,474 participants. HT was ascertained at visit 1 (1987-1989), and incident AF was identified by ECGs conducted during study examinations at each visit, hospital discharge codes, and death certificates. We used the Kaplan-Meier estimate to compute the cumulative incidence of AF by the HT subgroup...

Stroke represents the third - leading cause of death after heart and neoplastic is ease and is one of the biggest cause of disability worldwide. Cardioembolism, through its principal mechanism - atrial fibrillation - constitute an important cause of ischemic stroke. Otherwise, left ventricular hypertrophy (LVH) has been associated with a twofold increase in stroke risk. The study aims at highlighting significant associations between several risk factors of stroke -LVH and atrial fibrillation (AF), respectively LVH and cardiac stenosis contributeng to ischemic stroke...

Influenza infection has been identified as a triggering or exacerbating factor for cardiovascular events. To analyse the effect of influenza vaccination on cardiovascular disease, a systematic search of studies published between 2009-2019 was conducted. All the studies that evaluated the effect of vaccination against influenza on cardiovascular events and their outcome were considered. Finally, 30 of the 1147 identified studies were included. These studies show a protective effect of the influenza vaccine on the development of cardiovascular events (myocardial infarction, cerebrovascular accidents, atrial fibrillation, and heart failure) and on the worsening of these conditions...

BACKGROUND: Several scores were available for predicting atrial fibrillation (AF) recurrence post radiofrequency ablation. However, the role of different scores predicting AF recurrence after ablation in patients with concurrent AF and pulmonary diseases (PDs) remained obscure. Herein, we aimed to investigate their predicting values and differences in patients with concurrent AF and PDs. METHODS: From January 2008 to April 2015, 304 patients with concurrent AF and PDs treated with catheter ablation were divided into 2 groups according to whether they experienced AF recurrence in our centers...

INTRODUCTION: Atrial fibrillation (AF) is the most common cardiac sustained arrhythmia, whose incidence and prevalence increase with age, representing a significant burden for health services in western countries. Older people contribute to the vast majority of patients affected from AF. EVIDENCE ACQUISITION: Although oral anticoagulant therapy represents the cornerstone for the prevention of ischemic stroke and its disabling consequences, several other interventions - including left atrial appendage occlusion (LAAO), catheter ablation (CA) of AF, and rhythm control strategy (RCS) - have proved to be potentially effective in reducing the incidence of AF-associated clinical complications...

RATIONALE: Dual atrioventricular node non-reentrant tachycardia (DAVNNRT) is a rare arrhythmia. We present a case of inappropriate implantable cardioverter defibrillator (ICD) therapy caused by DAVNNRT. DAVNNRT is easily misdiagnosed as atrial fibrillation and is often identified as ventricular tachycardia (VT) by the supraventricular tachycardia-ventricular tachycardia (SVT-VT) discriminator of the ICD. PATIENT CONCERNS: A 73-year-old man with ischemic heart disease (IHD) presented with palpitations accompanied by dyspnea and syncope...
