Clinical variables affecting recovery of left atrial mechanical function after cardioversion from atrial fibrillation.
OBJECTIVES We sought to evaluate the effect of clinical factors on recovery of atrial function after cardioversion for atrial fibrillation. BACKGROUND Lack of effective mechanical atrial function (EMAF) after cardioversion of atrial fibrillation predisposes to thromboembolic complications and delays improvement in functional capacity. METHODS Fifty-two patients underwent cardioversion (grou...
متن کاملNew onset atrial fibrillation after coronary artery bypasses grafting; an evaluation of mechanical left atrial function.
BACKGROUND This study attempted to identify the role of combined conventional and novel echocardiographic techniques in evaluation of left atrial (LA) function to predict the postoperative atrial fibrillation (POAF). METHODS In this cross-sectional study, subjects with sinus rhythm who were candidates for CABG were enrolled. Preoperative LA function was evaluated by conventional echocardiogra...
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...
متن کاملLeft atrial remodelling after short duration atrial fibrillation in hypertrophic hearts.
A trial fibrillation (AF) is the most common sustained cardiac arrhythmia found in hypertensive patients. AF causes atrial dilation, and progressive left atrial (LA) enlargement occurs once AF becomes chronic. In the Framingham heart study, LA enlargement was associated both with the duration of elevated blood pressure and with the level of systolic pressure. The mechanism by which hypertension...
متن کاملLeft ventricular diastolic function after electrical cardioversion of atrial fibrillation.
In chronic atrial fibrillation (AF) left ventricular function may gradually diminish as a result of an intrinsic tachycardiomyopathy. This tachycardia induced cardiomyopathy is characterised by decreased systolic function, ventricular dilation, and raised ventricular filling pressures. In such patients left ventricular systolic function may gradually improve after electrical cardioversion. Litt...
