5. Study Description
Brief Summary
Atrial fibrillation (AF) affects as many as 1 in 100 people and reduces the quality of life of large numbers of people in the UK and around the world. Catheter ablation is a minimally invasive treatment that has been developed to help eliminate AF. It is a complex procedure to perform so only a few hospitals are able to offer this treatment in the UK. A new technology allows the operator to guide their catheters (thin wires) in the patient by using a robotically steered sheath. This allows accurate and precise navigation that may improve the accuracy and integrity of ablation. We aim to prove whether this technology can make AF ablation easier and more effective.
Substudy: Platelet reactivity and activation in AF, and the impact of curative ablation. Blood and urine samples will be taken pre- and 3 months post ablation to see if platelet reactivity and activation are affected by AF compared to established normal ranges, and whether curative ablation impacts on this.
