Validation of the Durability of the Adenosine Effect in Verification of Pulmonary Vein Isolation
In Brief
A clinical study evaluating Adenosine arm for Atrial Fibrillation. Completed, enrolled 20 participants across 1 site.
Detailed Summary
Adenosine is used clinically to assess permanency of electrical isolation of pulmonary veins during atrial fibrillation ablation, however, the methodology has not been validated either in terms of the reproducibility of the adenosine response or the effect on clinical outcomes, namely whether using pulmonary vein reconnection to guide additional ablation lowers rate recurrent atrial fibrillation post ablation. Study will test the hypothesis that the response to adenosine used in this manner is reproducible over time.
Study Details
Timeline
Interventions
In the adenosine arm, 25 patients will be randomized to received 2 doses of adenosine 12 mg IV, 5 minutes apart after pulmonary vein isolation. During this time, will monitor for pulmonary vein reconnection, second dose of adenosine will be given only if no reconnection after initial dose. In the observation arm, 25 patients will be randomized to 10 minute period of observation for pulmonary vein reconnection after documentation of pulmonary vein isolation.
