Elevated Fibrosis Burden as Assessed by MRI Predicts Cryoballoon Ablation Failure.

values tested, and the overlap in designated areas of fibrosis between the PIH and IIR methods was modest. Caution must therefore be exercised when interpreting LA fibrosis from LGE-MRI, since the values and spatial pattern are methodology-dependent. This article is protected by copyright.
