Maryd I found Northwestern Memorial and Dr Davidson, an interventional cardiologist, after being hospitalized for an unrelated cause. It was there I learned I had CHF, a congenital heart defect – a subaortic membrane, probably from birth (mind you I was 65 at that time), 2 valves with severe, and 1 with moderate regurgitation. Dr Davidson started working with me on adjusting my medications, he tested me to find out if I would be a candidate for TAVR, since surgery was not an option. He has always been honest with me, answers all my questions, and makes suggestions. I went to Mayo Clinic for a second opinion and they confirmed everything I’d been told. Unless something new comes on the market, I will never be able to have surgery but knowing Dr Davidson is watching my health I’m comfortable for the time being. Go online to nm.org – it’s a good site.
