Pulmonary vein isolation for atrial fibrillation.
Nonpharmacological treatment for atrial fibrillation (AF) has evolved dramatically over the past 20 years. Pulmonary vein isolation, a catheter ablation technique developed in the last decade, prevents focal triggers in the pulmonary veins from initiating episodes of AF. Although the procedure initially involved focal ablation with a catheter directly in the pulmonary veins, investigators subse...
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 کاملPulmonary vein isolation for treatment of atrial fibrillation.
consecutive procedures of pulmonary vein isolation were performed for treatment of paroxysmal and persistent atrial fibrillation. These interventions constitute the initial experience of the Instituto Cardiovascular de Buenos Aires, where 260 procedures are currently performed each year. Our population consisted mainly of men with an average age of 55.58 years; 71.9% had no history of cardiovas...
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 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...
