Implication
May support AF ablation to improve LV function in HF; leaves open confirmation by randomized trials.
Structured PICO
Does catheter ablation for atrial fibrillation improve left ventricular function and symptoms in patients with congestive heart failure?
P
Population
58 consecutive patients with congestive heart failure and a left ventricular ejection fraction of less than 45 percent who were undergoing catheter ablation for atrial fibrillation.
I
Intervention
Catheter ablation for atrial fibrillation
C
Comparator
58 patients without congestive heart failure who were undergoing ablation for atrial fibrillation, matched according to age, sex, and classification of atrial fibrillation.
O
Outcome
Left ventricular function and dimensions, symptom score, exercise capacity, and quality of life at baseline and at months 1, 3, 6, and 12.surrogate
Catheter ablation for atrial fibrillation in patients with congestive heart failure significantly improves left ventricular function, symptoms, exercise capacity, and quality of life.
