“…These results are in agreement with previous reports that both cardioversion and ABL are associated with a reduction in LA size. 5,18 Atrial remodeling with SR may decrease, with a resultant improvement in effective atrial contractile function. In the present study, LA function improved from 1 week through 3 months after sinus conversion in patients with AF, and in patients with ablation, it decreased within 1 week.…”

trial fibrillation (AF) occurs in 0.4% of the general population, increasing to 5% in those over 65 years of age, and it is the most common arrhythmia, increasing cardiac morbidity and mortality. 1 AF is related to the structural and functional remodeling of the left atrium (LA) and ventricle (LV) because of persistent arrhythmia. 2,3 To restore sinus rhythm (SR), both electrical cardioversion (ECV) and radiofrequency (RF) catheter ablation (ABL) have proven to be effective treatment modalities for patients with AF. 4 Reverse morphological remodeling of the LA and improvement in LV diastolic and systolic functions after restoration of SR by either treatment modality have been demonstrated. 5 However, differences in the degree and the time course of functional reverse remodeling of the LA according to the each treatment modality have not been investigated. The objective of this study was to investigate the morphological and functional changes of the LA and LV in patients with sustained SR either after ABL or ECV. Circulation Journal Vol.72, December 2008 Methods Study PopulationSixty-three AF patients who had maintained SR for 3 months after either ECV (n=30, M:F 24:6, mean age 58.6± 9.3 years) or ABL (n=33, M:F 27:6, mean age 55.9±10.2 years) were included. Patients who underwent re-do ablation were excluded. Paroxysmal AF (PAF) was defined as the occurrence of 2 or more episodes of AF during the previous 12 months, typically lasting fewer than 7 days and terminating spontaneously. Persistent AF (PeAF) was defined as AF episodes lasting more than 7 days typically requiring cardioversion for restoration of SR. 6 The 29 of 30 patients had PeAF in the ECV group and 21 of 33 patients had PAF in the ABL group. All clinical information was obtained from medical records, and all patients completed a written informed consent form to participate in the study. ECVECV was performed if LA thrombi were not seen on transesophageal echocardiography. Direct current (DC) shock was delivered during sedation induced with intravenous midazolam (0.04 mg/kg) and pentothal sodium (1.5 mg/kg). One defibrillator pad with a 10-cm diameter was placed in the second intercostal space on the right side parasternally, the other was placed in a left-sided lateral position along the midaxillary line. The cardioversion procedure started with 70 J or 100 J of stored energy followed by 125 J and 150 J until the restoration of SR or failure to convert. Continuous electrocardiographic (ECG) monitoring was performed for several hours after the procedure to assess the maintenance of SR. Background The aim of this study was to assess whether the morphological and functional changes of the left atrium (LA) differ after catheter ablation (ABL) from those after electrical cardioversion (ECV) in atrial fibrillation (AF). Methods and Results AF patients who had maintained sinus rhythm for 3 months after either ECV (n=30) or ABL (n=33) were studied. Both 2-dimensional and Doppler echocardiography were performed at baseline, 1 week, 1 month, and 3 months aft...

“…Сократимость миокарда при ФП не является постоянной в связи с наличием зависимости между силой сокращения и длительностью сердечно-го цикла [63]. У больных с персистирующей ФП сред-ние объемы левого и правых предсердий со временем увеличиваются [64], а восстановление и сохранение си-нусового ритма приводит к их уменьшению [65]. При чреспищеводной ЭхоКГ продемонстрировано вос-становление сократимости левого предсердия и скорости кровотока после кардиоверсии, что указывает на об-ратимость предсердной кардиомиопатии у больных с ФП [66].…”
