Reentry Within the Cavotricuspid Isthmus: An Isthmus Dependent Circuit

Pacing and Clinical Electrophysiology, 2005
Background: We describe a new cavotricuspid isthmus (CTI) circuit. Methods: This study includes 8 patients referred for atrial flutter (AFL) ablation whose tachycardia circuit was confined to the septal CTI and the os of the coronary sinus (CSOS) region. Entrainment mapping was performed within the CTI, CSOS, and other right

The aortic isthmus.

Radiology, 1981
In chest radiographs of seven infants, the aortic knob, isthmus, and descending aorta rendered a figure 3 image identical to that seen in coarctation of the aorta. Awareness of this anatomic variation may aid in diagnosis and may help to prevent unnecessary cardiac catheterization.
