Atrial Fibrillation - post ablation

Just by curiosity, white wizzard, are you an electrophysiologist or cardiologist? You seem to know enough about AFIB to be convinced that I’ll put myself in trouble. Have you ever heard of someone getting an cryoablation and then die in an endurance event later on? I’m only 38, does it change how you think, or is age irrelevant?

Thanks for your concerns,
Eric
