Atrial Fibrillation Trial, Recruiting
Who may be able to join
AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI
Who might be able to join this trial:
- People aged 18 years or older
- People with a type of irregular heartbeat called atrial fibrillation (not caused by a heart valve problem) who are already scheduled to have two specific heart procedures: a procedure to correct the irregular heartbeat (ablation) and a procedure to close off a small pouch in the heart called the left atrial appendage (LAA)
- People who are willing to take part, understand the purpose of the trial, and have signed a consent form (either themselves or through a legal representative), and are willing to attend all follow-up appointments as required
Who may not be able to join:
- People who are allergic to contrast dye, or who have another condition that prevents them from having a cardiac CT scan or a type of X-ray imaging called DSA
- People whose CT scan images are not clear enough to allow accurate measurements of the left atrial appendage
- People whose imaging shows a blood clot in the left atrium or left atrial appendage
- People whose atrial fibrillation is related to a heart valve problem, specifically a mechanical heart valve replacement or a significant narrowing of the mitral valve
- People where the left atrial appendage measurements fall outside a specific range required for the procedure (confirm with trial site)
- Women of childbearing age who are planning to become pregnant during the study's follow-up period
- People who are currently enrolled in another clinical trial of a drug or medical device and have not yet completed that trial's main assessment points, where participation could affect the results or their ability to attend follow-up appointments
- People who the trial investigators consider unsuitable for any other reason
