May aid post-PVI risk stratification in paroxysmal AF; leaves open whether targeting reconductions improves outcomes.
Does the presence of adenosine-provoked dormant pulmonary vein conduction predict AF recurrence in patients with paroxysmal AF undergoing ablation?
The appearance of acute adenosine-provoked reconduction after pulmonary vein antrum isolation is an independent predictor of AF recurrence at 12 months, even when the dormant conduction is successfully eliminated by additional ablation.
Miyazaki et al. (2011) studied this question.
