I did not know Dr Marron was no longer in Mnpls.i saw him once ,was very fortunate. He said he believed that I would live a normal life as I was 65 already. He said he had respect for Mayo Clinic in Rochester Mn had the best equipment in the Country and he would go there if he needed cardiac care. There are 1 in 500 people born with this disease, but unfortunately they are not a ware of this. This hereditary disease is more noted every year thanks to Dr Marron.
