What I found enlightening is his explanation of why many with a fib have multiple ablations given that only the 4 corners or back wall are ablated rather than cells ablated on all ) walls of the L atrium. He also discusses the requirement of a highly skilled electrophysiologist and the necessity of considering “how big the fire” whether a fib is persistent or long standing or occasional stage with persistent and longer standing requiring a much more extensive ablation process. He says deeper cuts and advocates for radio frequency vs cry or pulse. Anyway, definitely worth a watch. Personally, I’m dealing with a cardiologist that won’t even put a referral in to the cardiac surgeons I have researched for opinions because he says I’ll end up with a pig valve and then will require a third surgery in 8-10 years. He is only offering me rate control with drugs or rhythm control with ablation and is anti surgery. Offered me another cardioversion when the first, on March 30 only lasted : days. What’s the point of another? Looks like cardioversion is only a temporary reset. Told me a fib cannot be cured….. cannot be fixed. I’d rather be out of it for 5-10 years than end up with pulmonary hypertension or a fib more locked in due to the passage of time and also a more enlarged L atrium meaning the a fib is almost impossible to fix. But im dealing with valvular stenosis and a fib together….making the situation more challenging. The cox maze 4, gold standard fix for a fib, could be done while the valve is fixed. Attempting to get a new cardiologist but this is Canada and Nova Scotia…. Not exactly progressive.
