Objectives
Narrative objectives1
If it is paroxysmal atrial fibrillation, it is confined to the heart muscle of the pulmonary vein and its surroundings, and it is the basis of treatment to electrically isolate these tissues from the left atrium. Left atrial circumferential and BOX isolation using anatomical indicators and electrophysiological indicators are recommended in the Guidelines of the Japanese Circulation Society. However, it is unknown comparison of atrial function for patients who underwent left atrial circumferential or BOX isolation for atrial fibrillation. Therefore, I would like to clarify these by using MRI.
