Left Roof Linear, Mitral Isthmus Linear and Left Anterior Septal Linear Ablation for Non-paroxysmal AF: PROMISED Trial.

CPVI: Achievement of a wide disconnection of the right and left pulmonary veins; Roof linear ablation: linear ablation in the left atria roof; Anterior septal linear ablation: linear ablation in the anterior septal linear which coursed from the middle of the right superior and inferior pulmonary veins or the middle of the right superior pulmonary vein to the mitral valve annulus; Mitral isthmus linear ablation: linear ablation in the mitral isthmus; Left atrial appendage closure: Occlusion of the left atrial appendage with a left atrial appendage occlusion device.

CPVI: Achievement of a wide disconnection of the right and left pulmonary veins; Left atrial appendage closure: Occlusion of the left atrial appendage with a left atrial appendage occlusion device.
