Left atrial epicardial adiposity and atrial fibrillation.
BACKGROUND Atrial fibrillation (AF) has been linked to inflammatory factors and obesity. Epicardial fat is a source of several inflammatory mediators related to the development of coronary artery disease. We hypothesized that periatrial fat may have a similar role in the development of AF. METHODS AND RESULTS Left atrium (LA) epicardial fat pad thickness was measured in consecutive cardiac CT...
متن کاملEffect of epicardial fat pad ablation on acute atrial electrical remodeling and inducibility of atrial fibrillation.
BACKGROUND Atrial electrical remodeling (AER) is the underlying mechanism of atrial fibrillation (AF). The present study investigated the impact of epicardial fat pad (FP) ablation on acute AER (AAER) and inducibility of AF. METHODS AND RESULTS AAER was performed in 28 mongrel dogs through 4-h rapid atrial pacing (RAP). Before RAP, 14 dogs (ablation group) underwent FP ablation, and the other...
متن کاملEpicardial Fat and Atrial Fibrillation: A Review.
Atrial fibrillation (AF) is a progressive disorder that increases with age. Obesity is an important risk factor for AF. Pericardial fat is an active adipose tissue in close proximity to the heart and has been shown to be a risk factor for structural as well as coronary artery disease independent of body mass index. Recent studies suggest a role of epicardial fat in atrial remodeling as well as ...
متن کاملStructural and functional remodeling of the left atrium: clinical and therapeutic implications for atrial fibrillation.
Left atrial (LA) structural and functional remodeling reflects a spectrum of pathophysiological changes that have occurred in response to specific stressors. These changes include alterations at the levels of ionic channels, cellular energy balance, neurohormonal expression, inflammatory response, and physiologic adaptations. There is convincing evidence demonstrating an important pathophysiolo...
متن کاملMechanical Discordance between Left Atrium and Left Atrial Appendage
During standard transesophageal echocardiographic examinations in sinus rhythm (SR) patients, the left atrial appendage (LAA) is not routinely assessed with Doppler. Despite having a SR, it is still possible to have irregular activity in the LAA. This situation is even more important for SR patients where assessment of the left atrium is often foregone. We describe a case where we encountered t...
