The ways in which cardiac disease states, extracardiac factors, and abnormal genetic control lead to the arrhythmia are discussed, including the potential therapeutic implications that might arise from an improved mechanistic understanding.
Abstract
Atrial fibrillation (AF) is an extremely common cardiac rhythm disorder that causes substantial morbidity and contributes to mortality. The mechanisms underlying AF are complex, involving both increased spontaneous ectopic firing of atrial cells and impulse reentry through atrial tissue. Over the past ten years, there has been enormous progress in understanding the underlying molecular pathobiology. This article reviews the basic mechanisms and molecular processes causing AF. We discuss the ways in which cardiac disease states, extracardiac factors, and abnormal genetic control lead to the arrhythmia. We conclude with a discussion of the potential therapeutic implications that might arise from an improved mechanistic understanding.

- 01 Apr 2012 - 
TL;DR: This 2012 Consensus Statement is to provide a state-of-the-art review of the field of catheter and surgical ablation of AF and to report the findings of a Task Force, convened by the Heart Rhythm Society, the European Heart Rhythm Association, and the European Cardiac Arrhythmia Society and charged with defining the indications, techniques, and outcomes of this procedure.

miR-133 and miR-30 Regulate Connective Tissue Growth Factor Implications for a Role of MicroRNAs in Myocardial Matrix Remodeling

TL;DR: The results show that both miR-133 and mi-30 directly downregulate CTGF, a key profibrotic protein, and thereby establish an important role for these miRNAs in the control of structural changes in the extracellular matrix of the myocardium.

Pathophysiology and Prevention of Atrial Fibrillation

TL;DR: Atrial fibrillation is a ubiquitous yet diverse cardiac arrhythmia whose incidence increases with age; with most forms of cardiac and some pulmonary diseases; and with a number of metabolic, toxic, endocrine, or genetic abnormalities.

Ionic mechanisms of electrical remodeling in human atrial fibrillation

TL;DR: AF in humans leads to important changes in atrial potassium and calcium currents that likely contribute to the decrease in APD and APD rate adaptation and are therefore important factors for the perpetuation of the arrhythmia.

Atrial L-Type Ca2+ Currents and Human Atrial Fibrillation

TL;DR: The reduction in functional I(Ca) density in myocytes from the atria of chronic AF patients may be an adaptive response to the arrhythmia-induced calcium overload, consistent with the concept that calcium overload is an important factor in the initiation of AF.

Sodium channel mutations and susceptibility to heart failure and atrial fibrillation.

TL;DR: To identify a novel gene for DCM at a previously mapped locus, define the spectrum of mutations in this gene within a DCM cohort, and determine the frequency of DCM among relatives inheriting a mutation, refined locus mapping revealed SCN5A, encoding the cardiac sodium channel, as a candidate gene.
