Spontaneous 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 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...
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 کاملLeft atrial-pulmonary vein reentrant tachycardia following pulmonary vein isolation.
Pulmonary vein isolation has become the cornerstone of ablation for atrial fibrillation. However, it is sometimes followed by the development of left atrial macro-reentrant tachycardia. There is evidence to suggest that the myocardial sleeves within the pulmonary veins may be implicated in the mechanism of the tachycardia. Here we present a case of a post-ablation macro-reentrant tachycardia, i...
متن کاملDifferential 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 ...
