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

- Your stroke caused mild to moderate physical or movement difficulties (not the most severe level of disability)
- You have been diagnosed with a type of irregular heartbeat called atrial fibrillation (AF), either coming and going (paroxysmal) or ongoing (persistent), confirmed by a heart tracing (ECG) or heart monitor at any point before your screening appointment
- Your risk score for stroke related to atrial fibrillation (called CHA2DS2-VA) is 2 or more points (confirm with trial site)
- The shape and structure of your heart's left upper chamber is suitable for a specific heart procedure (confirm with trial site)
- You have been taking blood thinning medication correctly for at least 4 weeks before joining
- You are able and willing to have a heart ultrasound performed through your throat (called a TOE or TEE scan), with no medical reasons preventing this

- Your atrial fibrillation is permanent (constant and not able to be corrected)
- Your atrial fibrillation has been continuous for more than one year
- A scan has found a blood clot inside your heart's left upper chamber

- You have had a major bleed in the 14 days before joining, or have ever had a bleed inside your skull
- You currently have an overactive thyroid gland
- You have had a heart attack within the last 90 days

- You have active or chronic inflammation around the heart (pericarditis or cardiac tamponade)
- There is no suitable access point in your blood vessels for the required heart procedures
