Supportive Trial Data
Results from the Pulmonary Vein Antrum Isolation (PVAI) versus AV node ablation with Bi-Ventricular Pacing for Treatment of Atrial Fibrillation in Patients with Congestive Heart Failure (PABA-CHF) study suggest that pulmonary vein (PV) isolation leads to better morphologic and functional results than atrioventricular (AV) node ablation with biventricular pacing for congestive heart failure (CHF) in patients with atrial fibrillation.
In this prospective, multicenter study, 41 patients were randomized to PV isolation and 40 to AV node ablation with biventricular pacing. At 6 months, patients in the PV isolation group had higher mean ejection fractions (35% vs 29%, p<0.001), greater 6 minute distances walked (340 vs 297 meters, p <0.001), and better quality of life scores as determined by the Minnesota Living with Heart Failure questionnaire (60 vs 82, p<0.001, where lower scores indicate better quality of life) than those in the AV node ablation arm.
These PABA-CHF study findings thus suggest the potential advantages of performing PV isolation over AV node ablation with biventricular pacing for this patient population.
Noted limitations of the study include using sites with extensive experience in performing ablations, an unblinded study design, and a relatively short follow-up time.
