Catheter ablation may benefit patients with atrial flutter b
Atrial flutter catheter ablation in patients without a history of atrial fibrillation reduced risk for death, stroke, HF and AF compared with medical management, according to an abstract presented at Heart Rhythm 2021.

The researchers analyzed the data of 3,784 patients diagnosed with AFL without a previous AF diagnosis. Outcomes of interest included total deaths, cardiac deaths, HF and AF admissions. Data were propensity matched for age, sex, comorbidities and medications.

Compared with those who were managed medically, patients who received AFL ablation and future AF ablation had reduced risk for all-cause death, cardiac death, HF and AF admission. Receiving only AFL ablation still lowered risk for all-cause death, cardiac death and HF admissions compared with medical management.

“Survival curve analysis showed that patients who had AFL ablation had a significantly better outcome in terms of total deaths, cardiovascular deaths, HF admissions and AF admissions compared to medically treated patients,” researchers wrote.
