Key result
MRI is superior to transesophageal echocardiography for depicting pulmonary vein structure and measuring blood flow velocity to identify stenosis after radiofrequency ablation.

May support MRI over transesophageal echocardiography for post-ablation pulmonary vein stenosis assessment; leaves open prospective validation.
Pulmonary vein stenosis is one of the frequent complications after radiofrequency ablation for atrial fibrillation. MRI plays an important role in depicting the pathoanatomic structure of the pulmonary veins, and measuring the blood flow velocity in the pulmonary veins before and after therapy, and is superior to transesophageal echocardiography for this purpose.
