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 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 کاملEffect of valsartan on atrial fibrillation recurrence following pulmonary vein isolation in patients
Pulmonary venous isolation has emerged as an effective therapy for atrial fibrillation (AF); however, AF recurrence is common. The aim of the present study was to investigate the effect of angiotensin receptor blockers (ARBs) on the recurrence rate of AF following ablation therapy. In total, 120 patients, who were scheduled for ablation, were randomly selected. The patients were randomly divide...
متن کاملSelective Versus Total Pulmonary Vein Isolation In Atrial Fibrillation Ablation.
One of the great discoveries in cardiac electrophysiology was the recognition of the crucial role of pulmonary vein (PV) myocardial sleeves for the initiation of atrial fibrillation (AF). Based on this concept, catheter ablation aiming at electrical isolation of all pulmonary veins has become the routine approach for of paroxysmal AF. Another concept implies selective isolation only of arrhythm...
متن کاملIs pulmonary vein isolation necessary for curing atrial fibrillation?
BACKGROUND Pulmonary veins (PVs) play a pivotal role in initiating and perpetuating atrial fibrillation (AF). We investigated if PV electrical isolation from the left atrium is required for curing AF. METHODS AND RESULT Fifty-one patients with paroxysmal or persistent AF underwent circumferential radiofrequency ablation of PV ostia performed with an anatomic approach. The end point of the abl...
