Although catheter ablation is an effective treatment for recurrent atrial fibrillation (AF), there is no consensus on the definition of success or follow-up strategies. Symptoms are the major motivation for undergoing catheter ablation in patients with AF, however it is well known that reliance on perception of AF by patients after AF ablation results in an underestimation of recurrence of the ...
BACKGROUND Atrial fibrillation (AF) is a common arrhythmia that causes numerous visits to emergency departments (ED). The aim of the FinFib2 study was to evaluate whether treatment of patients with AF in ED is consistent with the contemporary European Society of Cardiology (ESC) management guidelines. Here we report the results of antiarrhythmic drug therapy (AAD) in ED. METHODS All patients ...
The objective of this article is to review supraventricular arrhythmias emphasized the importance of atrial fibrillation (AF) and its novel therapeutic approach in dogs. Supraventricular arrhythmias include disturbances of impulse formation at sinus node, atria and junctional area or alterations of impulse conduction within the chamber above ventricles. Among those supraventricular arrhythmias,...
Background The occurrence of peri-operative AF after abdominal surgery is a clinical condition burdened by several complications, especially in the elderly [1-3]. When AF is successfully converted to sinus rhythm, it is unlikely to recur, and nearly all of these patients are discharged from the hospital in sinus rhythm. It is not clear how soon these patients may discontinue antiarrhythmic ther...
BACKGROUND Atrial fibrillation (AF) is a risk factor for stroke, especially when accompanied by other high-risk cardiovascular predictors. The Atrial Fibrillation Follow-up Investigation of Rhythm Management (AFFIRM) Study was a multicenter comparison of high-risk patients with AF who were randomized to either a sinus rhythm control or a rate control strategy. METHODS Physicians were encourag...
INTRODUCTION It is unclear whether early restoration of sinus rhythm in patients with persistent atrial arrhythmias after catheter ablation of atrial fibrillation (AF) facilitates reverse atrial remodeling and promotes long-term maintenance of sinus rhythm. The purpose of this study was to determine the relationship between the time to restoration of sinus rhythm after a recurrence of an atrial...
Atrial fibrillation (AF) is the most common human arrhythmia causing a significant public health burden. Restoration of sinus rhythm by cardioversion of the arrhythmia, performed either electrically or pharmacologically, has been a main therapeutic option for the treatment of AF patients during the last decades. After publication of several large randomized studies showing no significant benefi...
STUDY OBJECTIVES To compare the efficacy and safety of amiodarone and propafenone when used for the prevention of atrial fibrillation (AF) and maintenance of normal sinus rhythm in patients with refractory AF. DESIGN Prospective, randomized, single-blind trial. SETTING Tertiary cardiac referral center. PATIENTS One hundred forty-six consecutive patients (72 men; mean age, 63 +/- 10 years ...
BACKGROUND In patients with recurrent persistent atrial fibrillation (AF), vulnerability to AF persists indefinitely despite presumed completion of reverse electrical remodeling within days of return to normal sinus rhythm. Atrial electrical and anatomic remodeling and reverse remodeling were studied in a canine model of chronic AF. METHODS AND RESULTS Chronic AF was induced in 8 dogs by crea...
BACKGROUND Galectin-3 (Gal-3) is an emerging biomarker in heart failure that is involved in fibrosis and inflammation. However, its potential value as a prognostic marker in atrial fibrillation (AF) is unknown. The aim of this study was to assess the impact of AF catheter ablation on Gal-3 and evaluate its prognostic impact for predicting rhythm outcome after catheter ablation. METHODS Gal-3 ...
