%A Ashish Nabar %J Indian Pacing and Electrophysiology Journal %T A Re-analysis of Our Current Understanding of Isthmus-Dependent Atrial Flutter: Some Gaps, Some Hypotheses %X The macro-reentrant circuit of isthmus-dependent atrial flutter (AFL) is located in the right atrium around the tricuspid annulus. High acute success and low recurrence rate makes isthmus ablation a definitive therapy for patients with only AFL. However, a review of the literature suggests that, different aspects of this macro-reentrant circuit are still not entirely understood, while new information continues to emerge. The aim of this article is to discuss some gaps in our ?complete? understanding of isthmus-dependent AFL. Few hypotheses have been stated which are open to investigation. %N 1 %K Atrial Flutter; Isthmus-Dependent %P 23-31 %E Balbir Singh %E Yash Lokhandwala %E Johnson Francis %E Anup Gupta %V 1 %D 2001 %I Indian Pacing and Electrophysiology Group %L cogprints4331
