Cavotricuspid-Isthmus Dependent Flutter or Left-Sided Atrial Tachycardia?

J Invasive Cardiol. 2017 Aug;29(8):E92-E93.


A 52-year-old man with previous mitral valve replacement, cavotricuspid isthmus, and left-sided roof-line ablation for previous typical atrial flutter and tachycardia presented with recurrence of symptoms with an atrial tachycardia measuring 260 ms cycle length on electrocardiogram. Rhythmia electroanatomical mapping (Boston Scientific) was performed to understand the mechanism of arrhythmia and to guide ablative treatment.
