Dezoito pacientes apresentavam FA paroxística, 102 persistente e 21 pacientes FA persistente de longa duração. Foram avaliados os parâmetros funcionais do VE, volume do átrio esquerdo indexado (VAEi) e Doppler transmitral pulsado e Doppler tecidual do anel mitral (e' e E/e'). Foi realizado ecocardiograma transtorácico 30 dias antes e 12 meses após a ablação. Um total de 141 pacientes foi submetido à ablação por radiofrequência (RF) para o tratamento da FA refratária a drogas. Objetivo:Īvaliar o impacto da ablação da FA na estimativa da pressão de enchimento do VE. Entretanto, não se sabe se a restauração do ritmo sinusal pode reverter este processo. Successful AF ablation is associated with LA reverse remodeling and an improvement in LV filling pressure.Ītrial Fibrillation Atrial Remodeling Catheter Ablation Echocardiography Stroke Volume Ventricular FunctionĪ disfunção diastólica do ventrículo esquerdo (VE) está associada a novos episódios de fibrilação atrial (FA), e a estimativa das pressões de enchimento do VE através da razão E/e' está relacionada a um pior prognóstico em pacientes com FA. The success rate was lower in the long-standing persistent AF patient group (57% vs. Improvement of LV filling pressure assessed by a reduction in the E/e' ratio was observed only after successful ablation (11.5 ± 4.5 vs.
#CPT CODE OF ATRIAL FLUTTER ABLATION FREE#
One hundred seventeen patients (82.9%) were free of AF during the follow-up (average, 18 ± 5 months). Follow-up included electrocardiographic examination and 24-h Holter monitoring at 3, 6, and 12 months after ablation. Paroxysmal AF was present in 18 patients, persistent AF was present in 102 patients, and long-standing persistent AF in 21 patients.
LV functional parameters, left atrial volume index (LAVind), and transmitral pulsed and mitral annulus tissue Doppler (e' and E/e') were assessed. Transthoracic echocardiography was performed 30 days before and 12 months after ablation. Methods:Ī total of 141 patients underwent radiofrequency (RF) ablation to treat drug-refractory AF. To evaluate the impact of AF ablation on estimated LV filling pressure. However, it is unknown if restoring sinus rhythm reverses this process. Left ventricular (LV) diastolic dysfunction is associated with new-onset atrial fibrillation (AF), and the estimation of elevated LV filling pressures by E/e' ratio is related to worse outcomes in patients with AF.
