Challenges Associated with Interpreting Mechanisms of AF
Author(s): Caroline H Roney , Andrew L Wit , Nicholas S Peters Added: 3 years ago
Determining optimal treatment strategies for complex arrhythmogenesis in AF is confounded by the lack of consensus on the mechanisms causing AF. Fundamental to defining arrhythmogenic mechanisms of AF are the distinctions and interplay between functional features (determined by the electrophysiology of a cell) and structural features (determined by whether a structural or anatomical feature is… View more

Electrophysiology & Arrhythmia
Author(s): Konstantinos N Aronis , Rheeda L Ali , Jialiu A Liang , et al Added: 3 years ago
The pathophysiology of AF is complex and incompletely understood to date.1,2 AF is a progressive disease of the atria involving a multitude of mechanisms related to its initiation, maintenance and progression. Experimental evidence suggest that AF is characterised by alternations in atrial size, shape electrophysiology, autonomic innervation, and cardiomyocyte metabolism, as well as development… View more

Ventricular tachycardia (VT) in the context of structural heart disease is related to patchy or incomplete scar; usually arising from re-entrant circuits which are dependent on surviving channels of activation through scar tissue.1–3 These protected isthmuses are critical for maintaining VT, and an improved understanding of the characteristics of VT isthmuses is important in guiding strategies… View more

Atrial fibrillation (AF), the most common sustained arrhythmia, is a leading cause of stroke, and is associated with significant morbidity and mortality worldwide. Despite its frequency, clinical importance, and advances in technology and our knowledge of the molecular, ionic and physiological fundamentals of cardiac electrophysiology, our limited understanding of the mechanisms that initiate and… View more

Author(s): Zhao Liu , J Kevin Donahue Added: 3 years ago
In the United States, atrial fibrillation (AF) is the most common sustained cardiac arrhythmia affecting approximately six million patients and contributing to a greatly increased risk of stroke, heart failure (HF) and overall morbidity and mortality.1,2 The prevalence of AF is increasing as the average age of the population increases.3,4 Currently available therapies for AF are suboptimal… View more

Atrial Fibrillation Structural Substrates: Aetiology, Identification and Implications
Author(s): Ahmed M Al-Kaisey , Ramanathan Parameswaran , Jonathan M Kalman Added: 3 years ago
AF is the most common sustained cardiac rhythm disorder and is associated with increased morbidity and mortality. Since the first description of AF initiation by triggers from pulmonary veins sleeves, pulmonary vein isolation (PVI) has become the standard ablation strategy in patients with AF.1 However, freedom from the arrhythmia, particularly in non-paroxysmal AF, remains suboptimal, and it is… View more
