Insufficient Leaflet Remodeling in Patients With Atrial Fibrillation
نویسندگان
چکیده
Atrial fibrillation (AF) is a common cardiac rhythm disorder, found prominently among elderly patients and patients with heart failure. Prevalence of AF is increasing as society is aging and is predicted to double for the next 20 years. Research shows that AF causes left atrial (LA) and mitral annular dilatation; however, the relationship between annular dilatation caused by AF and mitral regurgitation (MR) still remains controversial.

Insufficient Leaflet Remodeling in Patients With Atrial Fibrillation: Association With the Severity of Mitral Regurgitation.
BACKGROUND The relationship between annular dilatation caused by atrial fibrillation (AF) and mitral regurgitation (MR) remains controversial. We hypothesized that the small ratio of total leaflet area/annulus area (TLA/AA), reflecting insufficient leaflet remodeling to annular dilatation, is a main component of MR in patients with AF. METHODS AND RESULTS Three-dimensional transesophageal ech...
متن کاملIncreased IL-17A in Atrial Fibrillation Correlates with Neutrophil to Lymphocyte Ratio
Background: Atrial Fibrillation (AF) is the most common cardiac arrhythmia and an independent risk factor for stroke among the elderly. A role for inflammation in the atrial remodeling as well as development and recurrence of AF is known. Objective: To compare IL-17A between patients with different types of AF and healthy individuals. Methods: IL-17A was measured in sera of 112 patients and 107...
متن کاملNew manifestations of electrophysiological remodeling of heart during experimental model of atrial fibrillation in cirrhotic rat isolated heart
Introduction: The present study is aimed to evaluate electrophysiological remodeling of atrioventricular (AV) node and ventricular conduction during experimental atrial fibrillation (AF) model in isolated heart of cirrhotic rats. Methods: Cirrhosis-induced electrophysiological remodeling was evaluated in 24 isolated retrogradely perfused rat hearts in 2 groups (control and cirrhotic). Cirrho...
متن کاملAssessment of P-wave indices as atrial fibrillation predictors in psoriasis patients
Background: Psoriasis is a prevalent chronic T cell mediated inflammatory skin disorder. Recent studies have reported an increase in the incidence of arrhythmia in psoriasis patients who run an excessive risk of metabolic syndrome and cardiovascular diseases. P-wave dispersion (PWD) and duration are important electrocardiographic (ECG) markers employed to anticipate the risk of atrial arrhythmi...
متن کاملClinical Significance of P Wave Dispersion in Prediction of Atrial Fibrillation in Patients with Acute Myocardial Infarction
Background: P wave dispersion (PWD) is defined as the difference between the maximum P wave duration (Pmax) and the minimum P wave duration (Pmin) in 12-leads of the surface electrocardiography. The aim of this study was to evaluate the values of PWD during atrial fibrillation (AF) after acute myocardial infarction (AMI). Methods: We prospectively evaluated atrial rhythms of 350 patients (251 m...
