متن کاملImpact of Atrial Fibrillation Ablation on Left Ventricular Filling Pressure and Left Atrial Remodeling
BACKGROUND Left ventricular (LV) diastolic dysfunction is associated with new-onset atrial fibrillation (AF), and the estimation of elevated LV filling pressures by E/e' ratio is related to worse outcomes in patients with AF. However, it is unknown if restoring sinus rhythm reverses this process. OBJECTIVE To evaluate the impact of AF ablation on estimated LV filling pressure. METHODS A tot...
متن کاملAssociation Between Left Atrial Stiffness Index and Atrial Fibrillation Recurrence in Patients Undergoing Left Atrial Ablation.
BACKGROUND Atrial fibrillation (AF) is associated with significant abnormalities of left atrial (LA) systolic and diastolic function. This study describes a novel measure, LA stiffness index, that estimates LA diastolic function and its association with clinical outcomes of catheter ablation. METHODS AND RESULTS A total of 219 AF patients referred for ablation (59% paroxysmal, mean CHA2DS2VAS...
متن کاملAtrial fibrillation and diffuse left ventricular fibrosis, a causal association?
Late gadolinium enhanced magnetic resonance imaging (MRI) is an established technique for quantification of dense myocardial fibrosis (1). Cohesive regions of myocardial fibrosis, such as infarcted myocardium, are characterized by expanded extracellular matrix due to replacement of normal myocytes with collagen. Gadolinium contrast agents perfuse into and wash out of normal myocardium relativel...
متن کاملImprovement of left atrial function and left atrial reverse remodeling after surgical treatment of atrial fibrillation.
Two-dimensional speckle tracking echocardiography (2D-STE) is an emerging technology for the evaluation of left atrial (LA) function. This technique is feasible, overcomes the limitations of tissue Doppler imaging and has been demonstrated to accurately assess atrial function during the different phases of the cardiac cycle (1). Atrial structural and electrical remodeling are the hallmarks of a...
