Preprocedural MRI is a valuable imaging modality for assessing pulmonary vein anatomy and stenosis prior to atrial fibrillation ablation.
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.
