AF-associated PV enlargement and branching patterns are hypothesis-generating; leaves open their impact on ablation outcomes pending prospective studies.
Are there differences in pulmonary vein dimensions and branching patterns between patients with paroxysmal or chronic atrial fibrillation and those with normal sinus rhythm?
Patients with atrial fibrillation exhibit significant dilation of superior pulmonary veins and frequent complex-branching patterns in inferior pulmonary veins, which may inform radiofrequency ablation strategies.
