Case report: Cryoballoon ablation of the mitral isthmus using a novel mapping system.
Patrick BadertscherErik WissnerPublished in: Pacing and clinical electrophysiology : PACE (2019)
Perimitral atrial flutter is commonly treated by deployment of a mitral isthmus line. However, the creation of a contiguous, transmural linear lesion across the anterior mitral isthmus using radiofrequency energy ablation is technically challenging and can be associated with major complications. Herein, we describe the successful deployment of a superolateral mitral isthmus line using the 28-mm cryoballoon in combination with a new mapping system.
