Pulmonary Vein Anatomy in Patients Undergoing Catheter Ablation of Atrial Fibrillation

Abstract

This study demonstrates that AF patient have larger PVs than control subjects and demonstrates the value of MRI in facilitating AF ablation. The benefits of preprocedural MRI of PVs include the ability to evaluate the number, size, and shape of the PVs. MRI also provides an assessment of the severity of PV stenosis.
