Introduction: We report 12 month outcome of patients with atrial flutter and depressed LVEF who underwent successful radiofrequency catheter ablation (RFCA). Methods: Patients with atrial flutter and depressed LVEF ≤40% were included over a 15 months period. Results: 15 patients were identified and follow up. Majority were male (86.7%) and mean age was 66.7±8.5 years. 80% of patients had ischemic heart disease. Distribution of NYHA status at baseline was as follow: class 1: 6.7%, class 2: 53.3%, class 3: 33.3% and class 4: 6.7%. Mean LVEF before ablation was 24±6.3%. Post-ablation mean LVEF increased significantly to 37.6±17.6% (p<0.01). Improved ejection fraction (>40%) post-ablation was noted in 46.7% of patient. The recurrence rate was 14% at 12 months. No significant different in baseline characteristic and recurrence rate at one year comparing those with improved LVEF (>40%) to poor LVEF (≤40%). Significant difference in NYHA class post-ablation in which 57% patients were at NYHA class 1 in LVEF>40% group as compare to none in LVEF ≤40% group, p=0.03. Conclusions: Atrial flutter ablation in patients with LVEF ≤40% was safe with a recurrence rate of 14% at 12 months follow-up. LVEF was significantly improved post-ablation. Of note those who attained LVEF >40% had significantly improved NYHA status.
