Cardiac Magnetic Resonance–Measured Left Atrial Volume and Function and Incident Atrial Fibrillation
Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with both cardiovascular and cerebrovascular morbidity and mortality. According to a population-based study, it is estimated that >2 million US adults have been diagnosed with AF, and by 2050, this number is expected to increase to 5.6 million. Given the high prevalence of AF, finding methods to identify individual...
متن کاملAssociation of left atrial function and left atrial enhancement in patients with atrial fibrillation: cardiac magnetic resonance study.
BACKGROUND Atrial fibrillation (AF) is associated with left atrial (LA) structural and functional changes. Cardiac magnetic resonance late gadolinium enhancement (LGE) and feature-tracking are capable of noninvasive quantification of LA fibrosis and myocardial motion, respectively. We sought to examine the association of phasic LA function with LA enhancement in patients with AF. METHODS AND ...
متن کاملCardiac Magnetic Resonance-Measured Left Atrial Volume and Function and Incident Atrial Fibrillation: Results From MESA (Multi-Ethnic Study of Atherosclerosis).
BACKGROUND Early detection of structural changes in left atrium (LA) before atrial fibrillation (AF) development could be helpful in identification of those at higher risk for AF. Using cardiac magnetic resonance imaging, we examined the association of LA volume and function, and incident AF in a multiethnic population free of clinical cardiovascular diseases. METHODS AND RESULTS In a case-co...
متن کاملLeft atrial volume measurements before and after left atrial ablation for the treatment of atrial fibrillation
Background Recent studies have demonstrated the usefulness of CMR imaging in the management of patients with cardiac arrhythmia. CMR imaging allows for more accurate measurement of various cardiac dimensions. Significant changes in LA volumes have previously been documented in patients who have undergone ablation therapy. However, these studies have relied on simple two dimensional measurement ...
متن کاملDeterminants of Left Atrial Volume in Patients with Atrial Fibrillation
INTRODUCTION Left atrial (LA) enlargement is an important risk factor for incident stroke and a key determinant for the success of rhythm control strategies in patients with atrial fibrillation (AF). However, factors associated with LA volume in AF patients remain poorly understood. METHODS Patients with paroxysmal or persistent AF were enrolled in this study. Real time 3-D echocardiography w...
