Tricuspid Isthmus Imaged by CARTOsound, Patients With Typical Atrial Flutter

April 29, 2010 updated by: Lawson Health Research Institute

Tricuspid Isthmus Architecture as Imaged by CARTOsound, Determines Ablation Times in Patients With Typical Atrial Flutter

The investigators propose a third hypothesis based on the anatomic observations made in pathological studies. The investigators hypothesize that the anatomic architecture determines the functional properties of the TV-IVC isthmus. As a result,

• Muscular bundles are preferential routes of conduction through the TV-IVC isthmus. The isthmus acts like a series of discreet conduction routes rather than as a sheet of tissue.

The muscular bundles form selective targets for ablation and therefore the entire anatomic line need not be ablated. This has direct implications for ablation of the isthmus.
