Atrial Fibrillation

An analysis of five U.S. medical claims databases suggests as many as 23% of 5.6 million to 6.6 million presumptive atrial fibrillation cases are undiagnosed, with many undiagnosed patients likely eligible for oral anticoagulant treatment.

Pulsed field ablation pulmonary vein isolation for atrial fibrillation may confer less damage to cardiac nerves and ganglia vs. cryoballoon ablation, researchers reported.

Assessing moderately accelerated, personalized backup heart rates vs. normal setting of 60 bpm in HFpEF with preexisting pacemaker.

Evaluating the reliability of the Electrographic Flow algorithm technology (Ablacon) to identify atrial fibrillation sources and guide ablation therapy in patients with persistent AF.

NEW ORLEANS — In patients with HF, race and ethnicity predicted the likelihood of in-hospital mortality and other outcomes after ablation for atrial fibrillation, researchers reported.

NEW ORLEANS — In the PULSED AF pivotal trial, pulsed field ablation of symptomatic atrial fibrillation yielded a low rate of adverse events and demonstrated effectiveness consistent with established ablation strategies at 1 year.

A next-generation left atrial appendage closure device was associated with low rates of poor outcomes and high rates of complete seal at 1 year, researchers reported at Cardiovascular Research Technologies.

Compared with warfarin, direct oral anticoagulants correlated with a reduced risk for kidney failure and declined kidney function among patients with nonvalvular atrial fibrillation, according to a retrospective study.

In patients with atrial fibrillation, compared with usual care, early rhythm control therapy reduced risk for poor outcomes in both sexes, according to new data from the EAST-AFNET 4 trial.

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