Thank you so much for this wonderfully detailed answer. I believe the Mayo Clinic is rated the very best. I live in western NC am 61 years and was diagnosed with IHSS now called HCM in 1997. I have a familial history of the same. I continued with raising family and working until now. Just with a few meds. But now things are much worse. I have apical hypertrophy and ablation may or may not work but still have never tried it and on Monday my cardiologist suggested heart transplant which scares me so. Thank you again and I wish you all the best and many days of happy health!!
