Whether in the atrium or the ventricle, macro-reentrant tachyarrhythmias are among the most challenging arrhythmias to eliminate with ablation. Namdar et al,1 in this installment of Teaching Rounds in Cardiac Electrophysiology, present and explain insightful findings from a patient with a complex macro-reentrant circuit encountered after prior cardiac surgery. They take us through a step-by-step approach and their thought process in identifying the eventual curative ablation target.
