About

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.

Full description

Patients undergoing atrial flutter ablation will have cartosound imaging done during procedure to determine if this will shorten ablation times.
