Atrial structural remodelling and restoration of atrial contraction after linear ablation for atrial fibrillation.
AIMS We determined late atrial function following a surgical linear endocardial radiofrequency (RF) ablation procedure that aimed to restore and maintain sinus rhythm (SR) in atrial fibrillation (AF). We tested the hypothesis that successful restoration of SR is accompanied by measurable mechanical atrial function that is at normal or near normal levels. METHODS Forty-seven patients who under...
متن کاملAtrial 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...
متن کاملAtrial Tachycardias Following Atrial Fibrillation Ablation
One of the most important proarrhythmic complications after left atrial (LA) ablation is regular atrial tachycardia (AT) or flutter. Those tachycardias that occur after atrial fibrillation (AF) ablation can cause even more severe symptoms than those from the original arrhythmia prior to the index ablation procedure since they are often incessant and associated with rapid ventricular response. D...
متن کاملRight atrial anatomical remodeling affects early outcomes of nonvalvular atrial fibrillation after radiofrequency ablation.
BACKGROUND The impact of the right atrial (RA) anatomical remodeling on outcomes of atrial fibrillation (AF) after radiofrequency ablation (RFA) is unclear. METHODS AND RESULTS Sixty-three patients (50 men, 57±10 years, 23 persistent AF [PeAF]) who underwent RFA for AF were enrolled. Both RA and left atrial (LA) volumes, measured with multidetector computed tomography, as well as echocardiogr...
متن کاملOrganized Atrial Tachycardias after Atrial Fibrillation Ablation
The efficacy of catheter-based ablation techniques to treat atrial fibrillation is limited not only by recurrences of this arrhythmia but also, and not less importantly, by new-onset organized atrial tachycardias. The incidence of such tachycardias depends on the type and duration of the baseline atrial fibrillation and specially on the ablation technique which was used during the index procedu...
