Differential effects of adenosine on pulmonary vein ectopy after pulmonary vein isolation: implications for arrhythmogenesis.
BACKGROUND The mechanism of pulmonary vein (PV) triggers of atrial fibrillation remains unclear. We performed adenosine (ADO) testing after PV isolation to characterize spontaneous dissociated PV rhythm and ADO-induced PV ectopy. METHODS AND RESULTS Seventy-four patients (61 men; age, 61±10 years) undergoing PV isolation for atrial fibrillation were studied. For each isolated PV, dissociated ...
متن کاملAdenosine-induced pulmonary vein ectopy as a predictor of recurrent atrial fibrillation after pulmonary vein isolation.
BACKGROUND Adenosine can unmask dormant pulmonary vein (PV) conduction after PV isolation. Adenosine can also induce ectopy in electrically silent PVs after isolation, possibly via activation of autonomic triggers. We sought to identify the implications of adenosine-induced PV ectopy for atrial fibrillation (AF) recurrence after PV isolation. METHODS AND RESULTS A total of 152 patients (age, ...
متن کاملSpontaneous and induced pulmonary vein tachycardia after pulmonary vein isolation.
A case is reported of recurrence of paroxysmal atrial fibrillation after pulmonary vein ablation. A second procedure achieved isolation of three pulmonary veins and showed persistence of pulmonary vein tachycardia in one with implications concerning the electrophysiology of atrial fibrillation.
متن کاملReflections on reconduction after pulmonary vein isolation
Cryoballoon has proven to be a formidable competitor in the field of novel technologies for the ablation of atrial fibrillation (AF). Several reports have shown this technique to be safe and effective in treating AF, with 59–74% freedom of paroxysmal AF and 42% of persistent AF, for more than 1 year. Its major complication is temporary phrenic palsy caused by the ablation of the right superior ...
متن کاملCircumferential pulmonary vein isolation: wait or stop early after initial successful pulmonary vein isolation?
AIMS Circumferential pulmonary vein isolation (PVI) is the current standard of interventional atrial fibrillation (Afib) therapy. However, recurrence rate of Afib varies considerably after ablation between different series and is mainly attributed to the recovery of pulmonary vein (PV) conduction after initial successful PVI. STUDY HYPOTHESIS Waiting longer during the initial PVI procedure an...
