Background: Pharmacological cardioversion of atrial fibrillation is a reasonable alternative for electrical cardioversion in acute atrial fibrillation. We compared the efficacy and safety of intravenous vernakalant and intravenous flecainide in patients with recent-onset (< 48 h) atrial fibrillation. Methods: A total of 200 consecutive patients, 100 patients undergoing cardioversion with intravenous vernakalant and 100 patients undergoing cardioversion with intravenous flecainide, were included in this single centre non-randomized retrospective study. The primary endpoint was conversion to sinus rhythm within 120 minutes from the drug administration. Results: Cardioversion was successful in 67% of patients treated with vernakalant and in 46% of patients treated with flecainide ( p=0.003). Vernakalant (odds ratio 1.99, 95% confidence interval 1.08–3.69, p=0.029) and female gender (odds ratio 2.48, 95% confidence interval 1.22–15.05, p=0.012) were significant predictors of successful cardioversion. The success rate of cardioversion was lowest among men treated with flecainide (36.9%). Patients treated with vernakalant were discharged earlier from the emergency department compared with those treated with flecainide (8.2 ± 4.7 h vs. 12.0 ± 6.0 h, p < 0.001). There was no difference in the complication rate between the groups. Vernakalant treated patients were older (59.3 ± 12.5 vs. 55.4 ± 13.0 years, p=0.03), had higher CHA2DS2-VASc score (1.4 ± 1.3 vs. 0.9 ± 1.2, p = 0.002) and were more often on beta-blocker medication (59% vs. 42%, p= 0.016) than flecainide treated patients. Conclusion: Vernakalant was safe, more effective and faster than flecainide in the cardioversion of recent-onset atrial fibrillation. The difference in efficacy was especially apparent among men.

Abstract Aims Rapid restoration of sinus rhythm using pharmacological cardioversion is commonly indicated in patients with symptomatic recent-onset atrial fibrillation (AF). The objectives of this large, international, multicenter observational study were to determine the safety and effectiveness of intravenous (IV) vernakalant for conversion of AF to sinus rhythm in daily practice. Methods and Results Consenting patients with symptomatic recent-onset AF (< 7 days) treated with IV vernakalant were enrolled and followed up to 24 h after the last infusion or until discharge, in order to determine the incidence of predefined serious adverse events (SAEs) and other observed SAEs and evaluate the conversion rate within the first 90 min. Overall, 2009 treatment episodes in 1778 patients were analyzed. The age of patients was 62.3 ± 13.0 years (mean ± standard deviation). Median AF duration before treatment was 11.1 h (IQR 5.4–27.0 h). A total of 28 SAEs occurred in 26 patients including 19 predefined SAEs, i.e., sinus arrest (n = 4, 0.2%), significant bradycardia (n = 11, 0.5%), significant hypotension (n = 2, 0.1%), and atrial flutter with 1:1 conduction (n = 2, 0.1%). There were no cases of sustained ventricular arrhythmias or deaths. All patients who experienced SAEs recovered fully (n = 25) or with sequelae (n = 1). Conversion rate to sinus rhythm was 70.2%, within a median of 12 min (IQR 8.0–28.0 min). Conclusions This large multicenter, international observational study confirms the good safety profile and the high effectiveness of vernakalant for the rapid cardioversion of recent-onset AF in daily hospital practice.

ABSTRACT (195 words) Pharmacological cardioversion using intravenous antiarrhythmic agents is commonly indicated in symptomatic patients with recent-onset atrial fibrillation (AF). Except in hemodynamically unstable patients who require emergency direct current electrical cardioversion, for the majority of hemodynamically stable patients, pharmacological cardioversion represents a valid option and requires the clinician to be familiar with the properties and use of antiarrhythmic agents. The main characteristics of selected intravenous antiarrhythmic agents for conversion of recent-onset AF, the reported success rates and possible adverse events are discussed. Among intravenous antiarrhythmics, flecainide, propafenone, amiodarone, sotalol, dofetilide, ibutilide and vernakalant are commonly used. Antazoline, an old antihistaminic agent with antiarrhythmic properties was also reported to give encouraging results. Intravenous flecainide and propafenone are the only class I agents still recommended by recent guidelines. Intravenous new class III agents as dofetilide and ibutilide have high and rapid efficacy in converting AF to sinus rhythm but require strict surveillance with ECG monitoring during and after intravenous administration because the potential risk of QT prolongation and Torsades de Pointes which can be prevented and properly managed. Vernakalant, a partial atrial selective was shown to have a high success rate and to be safe in real life use.

Abstract Purpose Pharmacological cardioversion (PCV) is commonly a primary option for termination of recent-onset atrial fibrillation (AF) at the emergency departments (ED), and there are reports proving that antazoline is a noteworthy agent to restore sinus rhythm. This is a sub-analysis of the CANT study evaluating the effectiveness and safety of antazoline in patients with AF at different stages of chronic kidney disease (CKD). Methods Total n=777 patients admitted to ED for the urgent termination of AF were included into this analysis. We analysed the results concerning effectiveness and safety of PCV with special consideration of antazoline, in patients at 3 stages of CKD defined on the basis of eGFR (CKD-EPI): Group I ≥60 mL/min (n=531), Group II 45–59 mL/min (n=149), and Group III &lt;45 mL/min (n=97). Primary end-point was the termination of AF, a restoration of a sinus rhythm and its persistence until discharge. Results Patients of group III were older and with higher prevalence of comorbidities, however, we have not found statistically significant differences in overall effectiveness of PCV in comparison with the other groups. In patients receiving amiodarone, the PCV success rate was similar in all the studied groups, but along with a renal function decline, it decreased in patients receiving antazoline (79.1 vs 35%; p&lt;0.001), and it increased close to a significant manner in patients receiving propafenone (69.9 vs 100%; p=0.067; Figure). In patients of Group I, antazoline restored a sinus rhythm as effectively as propafenone and amiodarone, however in patients of Group III, both antazoline and amiodarone became less effective in restoring a sinus rhythm than propafenone (p=0.002 and p=0.034, respectively). The rate of safety endpoint was highest in patients of Group III (eGFR&lt;45 mL/min), and it was significantly higher than in patients of Group I and II (p=0.008 and p=0.036, respectively). We have not observed antazoline-related adverse events in any of studied groups of patients. Conclusion This real-world registry analysis revealed a different influence of CKD on individual drug effectiveness, and while propafenone and amiodarone maintained their AF termination efficacy, antazoline became significantly less effective in restoring sinus rhythm. Its favourable safety profile has not changed. FUNDunding Acknowledgement Type of funding sources: Public Institution(s). Main funding source(s): The study received no external funding
