Arrhythmia Disorders News

In a real-world setting, a novel cryoballoon for atrial fibrillation ablation generated effective pulmonary vein isolation with relatively short procedure times, researchers reported.

Dronedarone was associated with lower incidence of permanent atrial fibrillation/atrial flutter, more return to permanent sinus rhythm and lower AF/atrial flutter burden vs. placebo, according to a post hoc analysis of the ATHENA trial.

Very high-power, short-duration ablation for PVI utilizing a novel catheter with a very close protocol vs. conventional contact force sensing AI-guided radiofrequency ablation.

Assessing atrial fibrillation recurrence post-ablation after administration of IV adenosine.

Effect of posterior wall isolation added to pulmonary vein isolation on freedom from AF.

Continuous monitoring via implantable loop recorder detected bradyarrhythmia in more than 20% of high-risk patients aged 70 years or older with no history of atrial fibrillation, researchers reported.

Among patients hospitalized with COVID-19, men were more likely than women to have CV complications, but the difference was not explained by lower rates of past CVD in women, researchers reported in BMJ Medicine.

Improved atrial fibrillation ablation strategies and technologies during the past decade are associated with a stepwise reduction in the rate of redo AF procedures, increased procedural volume and shortened procedure times, data show.

In out-of-hospital cardiac arrest, the number of volunteer responders arriving before an ambulance is associated with increased bystander defibrillation rates, researchers reported.

A trial of a gold-tipped contact force-sensing catheter for treatment of patients with atrial flutter met its primary endpoints, researchers reported at AF Symposium.
