Catheter ablation may significantly improve cardiac and renal function among AF patients with mid-range ejection fraction

The main aim of this study was the evaluation of the efficacy and safety of atrial fibrillation (AF) ablation those having left ventricular ejection fraction (LVEF) < 50%.

The key highlights of this study are:

• Postoperative sick sinus syndrome and inguinal hematoma were reported in one patient as complications.
• Emphasizing efficacy, improvements were noted in echocardiographic data, blood test values, and diuretic use.
• Following 60 months of follow-up, 86.1% of patients reported no AF recurrence.
• There were nine heart failure hospitalizations 11.4%) and five all-cause deaths constituting 11.4 % and 6.3%, respectively.
• There were no significant differences between the rEF and more groups.
• Researchers reported no significant predictors of AF recurrence in preoperative patient characteristics.

They said Atrial fibrillation ablation is tied to improved cardiac and renal function in patients with LVEF <50%. It also has fewer complications, they noted.

The study's limitations include small sample size, lack of follow-ups and long-term monitoring.
