Flutter clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Identification of Risk Factors for Atrial Fibrillation After Ablation of an Atrial Flutter by Radiofrequency of the Cavotricuspid Isthmus.

Start date: January 8, 2019
Phase:
Study type: Observational

Atrial flutter is a common condition that is effectively treated by ablation using radiofrequency. Due to its feasibility, effectiveness and low procedural risk, radiofrequency ablation is a first-line treatment of atrial flutter. Several studies have been published concerning the factors associated with the occurrence of atrial fibrillation during or after flutter ablation, in patients with and without clinical history of atrial fibrillation. 26 to 46% of patients are likely to develop it, according to ECG or Holter diagnoses. The figure rises to more than 50% with a diagnosis with an implantable loop recorder. In patients without a prior history of atrial fibrillation before ablation, anticoagulants are routinely administered 4-6 weeks after flutter removal by most cardiologists. Although there are no specific guidelines for anticoagulation after flutter ablation, it is currently recommended to treat the patient as for atrial fibrillation. It is therefore crucial to identify in advance patients at high risk of atrial fibrillation after flutter ablation, in order to assess the appropriateness of maintaining oral anticoagulant therapy. The objectives of this study are: - to evaluate the frequency and identify the factors predicting the occurrence of atrial fibrillation after flutter ablation - to determine the risk of a stroke occurring in patients with atrial fibrillation after flutter ablation. The database consists in patients of the CHU Brugmann Hospital treated between 1996 and 2018.
