About this study
Official title: Atrial Flutter Ablation in a Real World Population: A Multicenter Italian Registry (The LEONARDO Study)
The "LEONARDO" study is a non-randomized, multicenter, prospective study in which consecutive patients indicated for Atrial Flutter isthmus-dependent (AFL) ablation will be enrolled. Patients can be treated with any market released catheter for ablation. The decision to perform the ablation of AFL will be made based on clinical evaluation of the investigators according to their clinical practice. The study does not require specific surgical techniques. Patient time commitment for the study is approximately 12 months.The study has been designed to describe the italian clinical practice in relation to the approach of AFL ablation. In particular, the investigators will describe the methods for the validation of ablation success, the techniques adopted, and the patient management approaches in the participating centers.
Read the detailed description
Catheter ablation of Atrial Flutter has become an accepted alternative to pharmacologic therapy.The current guidelines recommend the catheter ablation at the first episode of AFL (Class IIa) or in any case of recurrent episodes of AFL (Class I). Recent studies have already demonstrated a high degree of procedural efficacy (higher than 90%). However, there are still two main areas of investigation. First, what is the best method to obtain an effective lesion. Second, what is the most reliable method to validate the procedure success.The present study is aimed at investigating these aspects in the current Italian clinical practice.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Subjects With Complete Bidirectional Conduction Block
Acute success is defined as the confirmation of complete bidirectional conduction block across the cavo-tricuspid isthmus. The percentage of subjects with confirmed conduction block will serve as the outcome measure.
Measured: Time Frame: within 30 minutes after ablation procedure
Secondary outcomes (6)
Recurrence of symptoms of AFL, measured as the proportion of patients reporting symptoms during follow-up
number of patients with symptoms of AFL during follow-up
Measured: 12 months
Recurrence of AFL, measured as the proportion of patients with an episode longer than 30s documented at 24h Holter ECG recording during follow-up
number of patients with recurrence of AFL documented at ECG recording during follow-up
Measured: 12 months
Lesion's validation criteria
agreement between acute ablation success and long-term absence of AFL recurrence
Measured: an average of 12 months following the ablation procedure
Ablation procedure time
- RadioFrequency time;
- ablation time;
- Fluoroscopy time
Measured: intraoperative
Acute adverse events
Measured: intraoperative
Adverse Events during Follow up
Measured: 12 months
