Hello, I am new to the Phoenix/Scottsdale area, and I have HCM. I have recently tested positive for Scleroderma which causes Cardiomyopathy. I'm not sure if I have it from the Scleroderma or from my mother who had HCM but she lasted until the age of 94. I have had this cardiac problem since my 30's. I have symptoms which are shortness of breadth, and skipped beats, I have recently been diagnosed with a 1.6 mil mass in my colon, and it was suggested that I have a Colonoscopy to have it either be removed or biopsied. I am afraid of having bad side effects to the anesthesia as I have never been operated on in my life. I am 70 years old. Can someone suggest a top dr. at the Az Mayo Clinic that i can go to before I have these procedures done. Thank you!
