Cardioversion

Pulsed field ablation lowered the odds of high residual atrial arrhythmia burden compared with thermal ablation for patients with atrial fibrillation at 1 year, according to a subanalysis of the ADVENT trial presented at Heart Rhythm 2024.

Catheter ablation for atrial fibrillation was associated with lower incidence of hospitalization for worsening HF vs. drug therapy in patients with HF with preserved ejection fraction, researchers reported.

In a proof-of-concept phase 2 trial, a novel SK ion channel inhibitor successfully converted atrial fibrillation to sinus rhythm compared with placebo.

PHILADELPHIA — A novel adhesive-based wearable cardioverter defibrillator was associated with high rates of patient compliance and low rates of adverse events, researchers reported at the American Heart Association Scientific Sessions.

After atrial fibrillation ablation, dronedarone was associated with lower risk for recurrent hospitalizations and repeat AF ablations compared with sotalol, researchers reported.

Pharmacological cardioversion followed by electrical cardioversion vs. electrical cardioversion alone in patients with acute atrial fibrillation.

Sinus rhythm was restored in an effective, safe and rapid manner using drug-shock or shock-only strategies among patients in the ED with acute atrial fibrillation, according to results of the RAFF-2 trial published in The Lancet.

Citing safety concerns, the Cardiovascular and Renal Drug Advisory Committee of the FDA voted 2-11 against approval of vernakalant for the rapid conversion of recent-onset atrial fibrillation.

PARIS — Early radiofrequency ablation was superior to antiarrhythmic drugs to delay the progression to persistent atrial fibrillation among patients with drug-refractory paroxysmal AF, according to 3-year data from the ATTEST trial presented at the European Society of Cardiology Congress.

PARIS — Cardioversion with maximum-fixed energy shocks was more effective than low-escalating energy shocks for the treatment of patients with atrial fibrillation, according to a late-breaking science presentation at the European Society of Cardiology Congress.
