Intravenous Cavutilide for Pharmacological Conversion of Paroxysmal and Persistent Atrial Fibrillation in Patients with Heart Failure.

Unlabelled: This work aimed to study the efficacy and safety of the class III antiarrhythmic agent cavutilide (Niferidil, Refralon) for pharmacological cardioversion in patients with paroxysmal and persistent atrial fibrillation (AF) and heart failure (HF).

Methods And Results: In this retrospective cohort study, 58 patients with stable HF (aged 69 [61;73] years, 30 males, 78% with persistent AF) and 274 patients without HF (aged 63 [57;70] years, 196 males, 56% with persistent AF) were included. The median AF duration in the group with HF was 35.

Early initiation of anti-relapse antiarrhythmic therapy in patients with atrial fibrillation and flutter after pharmacological cardioversion with refralon.

Aim      Evaluating the efficacy and safety of early administration of antirecurrence antiarrhythmic therapy (AAT) following restoration of sinus rhythm (SR) with refralon.Aim      Evaluating the efficacy and safety of early administration of antirecurrence antiarrhythmic therapy (AAT) following restoration of sinus rhythm (SR) with refralon.Material and methods  The study included 247 patients with atrial fibrillation/atrial flutter (AF/AFL) (142 men) who underwent pharmacological cardioversion (PCV) with refralon.

[Efficiency and safety of using the modified protocol for the administration of the domestic class III antiarrhythmic drug for the relief of paroxysmal atrial fibrillation].

Aim: Evaluation of the efficacy and safety of the modified refralon administration protocol for the relief of paroxysmal atrial fibrillation (AF).

Materials And Methods: The study included 39 patients (19 men, mean age 6312.8 years).

[LEOPARD syndrome].

LEOPARD syndrome with multiple lentigines (cardiomyopathic lentiginosis) is a rare, genetically predetermined disease with autosomal dominant inheritance. Prevalence of this syndrome is unknown. One of pathognomonic clinical manifestations of this syndrome is the presence of multiple lentiginous pigment spots all over the body.

[Cardiac magnetic resonance imaging with contrast enhancement in treatment of atrial fibrillation].

Catheter ablation is presently the main method for interventional treatment of atrial fibrillation (AF). Despite improvements of the method and accumulation of personnel's experience, incidence of recurrent AF following catheter interventions remains high. This review addresses a possibility of using contrast-enhanced cardiac magnetic resonance imaging to increase the effectiveness of interventional treatment of arrhythmia.
