NCT03867266

Brief Summary

The Ablation of the typical atrial flutter can be considered substantially anatomical, the investigators want to test a protocol that foresees the use a lesion index (AI) and that respects the Inter-Lesion Distance (ILD) ≤ 6 mm on the cavo-tricuspid isthmus (CTI) The investigators want to prove how the introduction of a lesion index combined with the continuity of lesion can allow a "first pass block" of the CTI decreasing total Radio-Frequency (RF) times

Sampling MethodProbability Sample
Study Population

Caucasian population regardless gender

You may qualify if:

  • paroxysmal, persistent and /or long standing atrial flutter even in the presence of structural heart disease
  • Informed consent form
  • Age equal or above 18 years
  • Skilled and willing to comply with all tests and follow up requirements
  • Patients that ,in the context of ablation for fibrillation atrial, should also undergo to typical flutter ablation: in this case the data collected will be those related to typical flutter ablation.

You may not qualify if:

  • Previous ablation for atrial flutter
  • Atrial flutter secondary to electrolyte imbalance, thyroid disease or to a reversible or non-cardiac cause
  • severe anemia,
  • sepsis in progress
  • Bypass procedure with coronary arterial artery in the last three months
  • Pending cardiac transplantation or other cardiac surgery
  • Pregnant or breastfeeding women
  • Acute disease or active systemic infection or sepsis
  • Documented left atrial thrombus
  • Unstable angina
  • Uncontrolled heart failure
  • Life expectancy of less than 12 months
  • Registration in any other study evaluating another device or medication
  • Presence of intramural thrombi, tumor or other anomalies that preclude the introduction of the catheter into the vein system
