Predictors of non-pulmonary vein ectopic beats initiating paroxysmal atrial fibrillation: implication for catheter ablation.
OBJECTIVES The purpose of this study was to investigate the predictor of non-pulmonary vein (PV) ectopic beats initiating paroxysmal atrial fibrillation (PAF). BACKGROUND Non-PV ectopic beats can initiate PAF in some patients and play an important role in the recurrence of PAF after PV isolation. Information on the predictors of non-PV ectopic beats initiating PAF is unknown. METHODS This s...
متن کاملRapid and stable re-entry within the pulmonary vein as a mechanism initiating paroxysmal atrial fibrillation.
OBJECTIVES We investigated the hypothesis that re-entrant pulmonary vein (PV) tachycardias may serve as a mechanism for initiating and sustaining paroxysmal atrial fibrillation (PAF). BACKGROUND The mechanisms of rapid repetitive discharges from the PV initiating PAF remain incompletely understood. Pulmonary vein myocardial sleeves appear to provide a favorable substrate for re-entry formatio...
متن کاملPulmonary vein isolation for paroxysmal and persistent atrial fibrillation.
BACKGROUND The pulmonary veins (PVs) have been demonstrated to often play an important role in generating atrial fibrillation (AF). The purpose of this study was to determine the safety and efficacy of segmental PV isolation in patients with paroxysmal or persistent AF. METHODS AND RESULTS In 70 consecutive patients (mean age, 53 +/- 11 years) with paroxysmal (58) or persistent (12) AF, segme...
متن کاملPulmonary vein thrombi in a patient with paroxysmal atrial fibrillation
Atrial fibrillation is a serious clinical problem, which is associated with systemic thrombosis such as cerebral infarction. Pulmonary vein myocardiumpromotes andmaintains atrial fibrillation. Catheter ablation is done to cure atrial fibrillation to cut down the current flow from pulmonary vein myocardium. Although pulmonary vein thrombi (PVT) are thought to be a rare complication of certain tu...
متن کاملPulmonary vein morphology in patients with paroxysmal atrial fibrillation initiated by ectopic beats originating from the pulmonary veins: implications for catheter ablation.
BACKGROUND Successful ablation of ectopic beats originating from the pulmonary veins (PV) could eliminate paroxysmal atrial fibrillation (PAF). However, information about the structure of the PV in patients with PAF that is initiated by PV ectopic beats has not been reported. METHODS AND RESULTS We studied the morphology of the PVs and measured their diameters in 3 groups of patients. Group I...
