Atrial Fibrillation Trial, Recruiting

Written by an AI model from the ClinicalTrials.gov eligibility criteria and checked on a sample basis. Please confirm against the original criteria.

Who might be able to join this trial:

• People who are 18 years of age or older
• People who have had at least one confirmed episode of a specific type of irregular heart rhythm called atrial flutter, recorded by a heart tracing (ECG or Holter monitor) in the 180 days before joining the trial — recordings from other hospitals are accepted
• People who understand the purpose of the study, are willing to take part, sign a consent form, and agree to attend all required follow-up appointments

Who may not be able to join:

• People who have previously had a procedure to treat atrial flutter in a specific area of the heart (called cavo-tricuspid isthmus ablation)
• People with unstable angina (chest pain that is unpredictable or occurring at rest)
• People whose atrial flutter is caused by an electrolyte imbalance, thyroid condition, or another reversible underlying cause
• People who have had a heart attack, open-heart bypass surgery, or a procedure to open blocked arteries (such as a stent) within the past three months
• People whose heart failure has been rated as severe (Grade III or IV on a standard medical scale) at the time of assessment
• People who have an implanted heart device such as a defibrillator, cardiac resynchronisation device, or pacemaker
• People who have had a recorded tumour, blood clot, or known clotting disorder in the heart or blood vessels within the past 90 days
• People with serious structural heart problems — such as narrowing or malformation of the tricuspid heart valve, or other birth-related heart conditions — that would prevent the ablation procedure from being performed
• People who have previously had a tricuspid heart valve replaced with a metal valve
• People who have had a stroke, blood clot event, or a brief stroke-like episode (transient ischaemic attack) within the past six months
• People who have a blood clot, tumour, or other abnormality in blood vessels that would interfere with placing a catheter or needle during the procedure
• People with serious lung disease, high blood pressure in the lungs, or any lung condition causing abnormal oxygen levels or severe breathing difficulties
• People for whom blood-thinning medication is not safe to use, or who have a history of abnormal clotting or bleeding
• People with an active infection affecting the whole body
• People with significantly reduced kidney function (creatinine levels more than twice the normal upper limit) or who have a history of kidney dialysis
• People who are pregnant, breastfeeding, or unable to use contraception during the study period
• People who are already participating in another clinical trial involving a different device or medication at the same time
• People whose life expectancy is less than 12 months, for example due to advanced cancer
• People who have any other condition or abnormality that the trial investigator considers would make participation unsuitable (confirm with trial site)
