Long decrementally conduction accessory atrioventricular (AV) fibers are rare and their successful mapping and ablation is often challenging due to its predominatly intramuscular course. The use of 3D-mapping systems have the potential to improve successful mapping and ablation of these special pathways. We describe a case of a young healthy woman with a Mahaim fiber, who had six previous failed ablation attemps in three different high volume EP centers in Germany. Using high density mapping with the Advisor TM HD-Grid Catheter (Abbott), the ventricular insertion site of the long atrioventricular fiber could be visualized with finally consecutive successful ablation.
