AF Septal Pacing (Clinical Investigation Plan)
In Brief
A clinical study evaluating Pulmonary vein ablation for Paroxysmal Atrial Fibrillation and Persistent Atrial Fibrillation. Completed, enrolled 16 participants across 3 sites in 2 countries.
Detailed Summary
The purpose of this non-randomized, non-controlled, acute, single-arm research study is to evaluate the feasibility to obtain a stable position of a ring of stimulation electrodes on the interatrial septum. The possibility to terminate atrial arrythmias will also be evaluated.
Study Details
Timeline
Interventions
After pulmonary vein isolation, during the routine waiting time of half an hour to confirm efficacy of the ablation, the septal catheter, already in place in right atrium, will be positioned on the interatrial septum. If the patient will not be in sinus rhythm, he/she will be externally cardioverted in order to determine pacing thresholds and impedances on all septal catheter electrodes. Next, atrial fibrillation will be induced by rapid atrial pacing.AF cycle length will be determined in the left atrial appendage, during 1 minute of atrial fibrillation using ablation catheter electrodes. Subsequently, a pacing scheme will be applied and capture on decapolar recording catheters, already in place for the standard ablation procedure will be assessed as well as AF termination.
