Tricuspid Isthmus Imaged by CARTOsound, Patients With Typical Atrial Flutter
- Conditions
- Atrial Flutter
- Interventions
- Device: tricuspid isthmus imaging with Cartosound
- Registration Number
- NCT01113788
- Lead Sponsor
- Lawson Health Research Institute
- Brief Summary
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.
- Detailed Description
Patients undergoing atrial flutter ablation will have cartosound imaging done during procedure to determine if this will shorten ablation times.
