Description
Summary:To identify and characterise pre-procedural and procedural parameters which predict maintenance of sinus rhythm after a first circumferential pulmonary vein isolation (CPVI) for recurrent atrial fibrillation (AF). 100 patients (54±10 yrs) undergoing CARTO-guided CPVI for symptomatic drug refractory, paroxysmal or shortstanding persistent AF were studied. The endpoint was complete electrical isolation within the encircled regions. 3D left atrial (LA) volume was measured by CARTO geometry. Follow-up examinations (symptoms, ECG, 24-hour ECG recording) were performed at 1 and 3 months and every 3 months thereafter. After the first CPVI, 71 patients (71%) were free of AF without antiarrhythmic drug therapy (follow up:28±11 months). The only independent and significant predictors for freedom of AF after the first CPVI were duration of AF history and 3D LA volume (p
