Pulmonary Vein Morphology in Patients With Paroxysmal Atrial Fibrillation Initiated by Ectopic Beats Originating From the Pulmonary Veins Implications for Catheter Ablation

摘要: Background—Successful ablation of ectopic beats originating from the pulmonary veins (PV) could eliminate paroxysmal atrial fibrillation (PAF). However, information about structure PV in patients with PAF that is initiated by has not been reported. Methods and Results—We studied morphology PVs measured their diameters 3 groups patients. Group I included 52 (aged 66±14 years; 44 men) focal (AF) PVs. II 8 50±10 AF superior vena cava or cristal terminalis. III 23 control 55±16 17 men). Of patients, 11 had AV node 12 reentrant tachycardia. After an transseptal procedure, selective angiography using a biplane system right anterior oblique view 30 degrees, left 60 cranial angle 20 degrees was performed. The ostial proximal portions...
