متن کاملMechanisms by which adenosine restores conduction in dormant canine pulmonary veins.
BACKGROUND Adenosine acutely reconnects pulmonary veins (PVs) after radiofrequency application, revealing "dormant conduction" and identifying PVs at risk of reconnection, but the underlying mechanisms are unknown. METHODS AND RESULTS Canine PV and left-atrial (LA) action potentials were recorded with standard microelectrodes and ionic currents with whole-cell patch clamp before and after ade...
متن کاملWhat’s to come after isolation of the pulmonary veins?
believe this may be due to inexperience with this novel technology, although other influential factors could be that this study, in contrast to others, also included some patients with persistent AF and had a longer follow-up period. Unfortunately, the study did not report how many pulmonary veins were in fact electrically reconnected with re-ablation procedures. This could provide more informa...
متن کاملValue of adenosine test to reveal dormant conduction or adenosine-induced atrial fibrillation after pulmonary vein isolation
Background Recent studies investigating the implications of additional ablation guided by dormant pulmonary vein (PV) conduction testing using adenosine showed conflicting results, and the data about atrial fibrillation (AF) recurrence after trigger site elimination in adenosine-induced AF are still lacking. Methods Of 846 patients with paroxysmal AF (PAF) who underwent PV isolation (PVI), ad...
متن کاملPulmonary vein isolation: comparison of bipolar and unipolar electrograms at successful and unsuccessful ostial ablation sites.
INTRODUCTION No prior studies have quantitatively analyzed the characteristics of bipolar or unipolar electrograms that may be helpful in identifying successful ostial ablation sites in patients with atrial fibrillation undergoing segmental pulmonary vein isolation. METHODS AND RESULTS The characteristics of bipolar and unipolar electrograms recorded at 185 successful and 120 unsuccessful ost...
