Filter by:The investigators hypothesized that revealing the incidence of AF following RFA of the CTI and cryoablation PVI reduces incidence of AF following RFA of the CTI.
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.
The purpose of this study is to compare the efficacy of 4 mm irrigated catheters with 2 mm irrigated catheters for ablation of typical flutter.It's a prospective randomised multicenter study.
Patients undergoing atrial flutter ablation will be randomized to either the standard ablation approach or voltage targeted approach. Patients will be followed for one year to assess outcome of the ablation technique
