Does differentiating the left atrial tract from pulmonary vein potentials guide effective radiofrequency ablation in patients with paroxysmal atrial fibrillation?

Population

10 patients with paroxysmal atrial fibrillation (PAF) who had a recording of double potentials (DPs) in or around the left pulmonary vein (PV), mean age 60 +/- 12 years.

Intervention

Radiofrequency ablation guided by the earliest activation of the left atrial tract (LAT) potential or pulmonary vein (PV) potentials.

Comparator

Comparison between patients with the second deflection of DPs due to LAT activation (Group I, n=5) versus PV musculature activation (Group II, n=5).

Outcome

Electrophysiological characteristics (coronary sinus ostium to D2 interval) and success rate of radiofrequency ablation in eliminating PAF.surrogate

Differentiating left atrial tract from pulmonary vein potentials using an electrophysiological approach is feasible and may be important for guiding successful radiofrequency ablation of paroxysmal atrial fibrillation.
