I was diagnosed with AF 6 months ago and my cardiologist seemed keen for me to have an ablation, now booked for June. At present I'm taking bisoporol and warfarin, and apart from a little tiredness, having no adverse symptoms. I've been told that there is a 1 in 200 chance of a stroke following or during the procedure. (I'm 69 so this may be a contributory factor). Does anyone know the risk of stroke with continued medication? Is it greater than with an ablation?
