Detection and Quantification of Left Atrial Structural Remodeling With Delayed-Enhancement Magnetic Resonance Imaging in Patients With Atrial Fibrillation
Background— Atrial fibrillation (AF) is associated with diffuse left atrial fibrosis and a reduction in endocardial voltage. These changes are indicators of AF severity and appear to be predictors ofExpand

Evaluation of Left Atrial Lesions After Initial and Repeat Atrial Fibrillation Ablation: Lessons Learned From Delayed-Enhancement MRI in Repeat Ablation Procedures
Background—We evaluated scar lesions after initial and repeat catheter ablation of atrial fibrillation (AF) and correlated these regions to low-voltage tissue on repeat electroanatomic mapping. WeExpand

New magnetic resonance imaging-based method for defining the extent of left atrial wall injury after the ablation of atrial fibrillation.
OBJECTIVES We describe a noninvasive method of detecting and quantifying left atrial (LA) wall injury after pulmonary vein antrum isolation (PVAI) in patients with atrial fibrillation (AF). Using aExpand

Cryoballoon in AF ablation: impact of PV ovality on AF recurrence.
INTRODUCTION Complete occlusion of the pulmonary veins (PV) is crucial for successful PV isolation. While two different sizes of cryoballoons (23 and 28 mm) are available, complete occlusion is notExpand
