Conventional unipolar radiofrequency (RF) catheter ablation is limited by maximal lesion depths that fail to eliminate ventricular tachycardias with deep midmyocardial critical components. The use of multipolar mapping catheters as an active part of the ablation circuit may provide a solution to the...
