I had mitrol valve replacement in 2014. I was recently diagnosed with dialated cardiomyopathy. I’m getting a muga scan end of Jan 2019 to get a better read on my EF rate cause it’s right on the cusp of heart failure. I’m trying to find more info on this diagnosis. Supposedly, life span has increased from 2 to 5 years to possibly 7 or more years. I have a pacemaker but expect to get a defibrillator put in to help avoid possible sudden death. The muga scan will determine my need for this. Any one have any current information on this diagnosis.
