I had an av noldal ablation when I was about 25, I’m 36 now. Having the procedure is the best thing I have ever done. Before I had it I was virtually an invalid, after it my life changed totally. I could suddenly do sports, exercise. I had a baby who is now a health six years old. I would recommend an av nodal ablation to anyone, even if it leaves you pacemaker dependent, its never bothered me in the slightest.
I am a 43yr old female, and had an av node ablation in 99. I am pacemaker dependent from the procedure.(means my heart no longer beats on its own) I feel much less tired, an was able to regain a pretty normal life after the procedure. I thank God every day for it. I was able to stop taking cardiac meds. which helps lessen the tiredness too. Research complications of this procedure before proceeding and discuss this with your mom and her doctor, knowledge is power! stay strong!
