The impact of atrial fibrillation paroxysms on left atrial function measured by strain imaging

strain evaluation of left atrial function: ready for the future?

Catheter ablation of paroxysmal atrial fibrillation improves cardiac function: a prospective study on the impact of atrial fibrillation ablation on left ventricular function assessed by magnetic resonance imaging.

AIMS Beneficial effects of atrial fibrillation (AF) ablation have been demonstrated in patients with congestive heart failure (CHF) and significantly impaired left ventricular ejection fraction (LVEF). However, the impact of pulmonary vein isolation (PVI) on cardiac function in patients with paroxysmal AF and impaired LVEF remains under discussion. This study aimed to evaluate the impact of PVI...

comparison of left atrial function between hypertensive patients with normal atrial size and normotensive subjects using strain rate imaging technique

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...

Strain echocardiographic assessment of left atrial function predicts recurrence of atrial fibrillation

AIMS We evaluated if a dispersed left atrial (LA) contraction pattern was related to atrial fibrillation (AF) in patients with normal left ventricular (LV) function, and normal or mildly enlarged left atrium. METHODS AND RESULTS We included 61 patients with paroxysmal AF (PAF). Of these, 30 had not while 31 had recurrence of AF after radiofrequency ablation (RFA). Twenty healthy individuals w...
