The purpose

This study will be a single blind prospective randomised control trial in patients undergoing ablation for the treatment of typical atrial flutter, with the aim of investigating the benefit of a new impedance-based computer software application which measures tissue contact between the ablation catheter and the inside of the heart. The investigators hope to demonstrate that the use of this tissue contact information reduces ablation time, Xray time, and procedure time required to complete the procedure successfully. Study participants will be randomly assigned to undergo their procedure with or without this contact data displayed for the doctor performing the ablation to see. The acute procedural endpoint of ablation is successful conduction block across the cavotricuspid isthmus of the right atrium. If the outcome of this study is positive, it will have a significant beneficial impact on this procedure, reducing procedure length, patient discomfort, and potentially reducing risk for the patient, recurrent arrythmia symptoms, and the need for repeat procedures later on.

Provided treatments

  • Procedure: Radiofrequency ablation utilising the ECI contact software
  • Procedure: Radiofrequency ablation without the use of ECI contact data
