LVOT Bigeminy with NSVT/PSVT

I have had Bigeminy in the LVOT that is now coupled with NSVT and PSVT going on two years. I had an locally unsuccessful ablation in 2020. I am getting ready to come to Mayo Clinic for a new ablation procedure in April 2021. My question is are there others that have arrhythmia like this without known heart disease or blood pressure issues and what was their experience? I am a bit nervous I have been reading about the risk of left sided heart ablation and I am a bit scared.
