Atrial fibrosis in atrial fibrillation pre-ablation assessed by CMR: impact in atrial size and function?

Methods 47 (42 male, 42±8 years-old) consecutive patients (pts) with paroxysmal AF and indication to ablation were included. Exclusion criteria for CMR: non-sinus rhythm and general contra-indications. Before ablation all underwent CMR for left atrial angiography for CARTO mapping. Using CMR, the following variables were assessed: left ventricle (LV) and left atrium (LA) volumes and ejection fr...

Impact of left atrial fibrosis and left atrial size on the outcome of catheter ablation for atrial fibrillation.

BACKGROUND Left atrial (LA) dilatation is an important risk factor for recurrence of atrial fibrillation (AF) after radiofrequency catheter ablation (RFCA). However, the clinical applications to select patients eligible for RFCA according to LA size is limited. Additional pre-procedural assessment of LA fibrosis might improve patient selection for RFCA. OBJECTIVE To investigate the impact of ...

radiofrequency atrial fibrillation ablation technique in patients with mitral valve surgery and left atrial reduction procedures

background: about half of all patients who undergo mitral valve surgery suffer from atrial fibrillation (af). cox described the surgical cut-and-sew maze procedure, which is an effective surgical method but has some complications. this study was designed to evaluate the efficacy of a substitution method of radiofrequency ablation (rfa) for patients undergoing mitral valve surgery with af. metho...

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...
