Cognitive deficits following catheter ablation for AF appear short-lived
A new study published in JACC: Clinical Electrophysiology suggests that postoperative cognitive dysfunction (POCD) was noticed after atrial fibrillation (AF) ablation. But this was just temporary; at the 12-month follow-up, the patient had fully recovered.
Following atrial fibrillation ablation, there have been reports of early postoperative cognitive impairment. POCD's long-term persistence, however, is uncertain. In order to ascertain if AF catheter ablation is linked to persistent cognitive impairment at 12-month follow-up, Ahmed Al-Kaisey and colleagues undertook this study.
In this prospective trial, 100 patients with symptomatic AF who had at least one antiarrhythmic treatment failure were randomized to receive either continued medical therapy or AF catheter ablation, and they were then monitored for a year after the procedure. Six cognitive tests that were given at baseline and again after 3, 6, and 12 months of follow-up were used to measure changes in cognitive performance.
