Mitral valve question. My wife had a mitral valve replaced in November 2018 and was told by both Doctors that she would fill a lot stronger after the new valve is in. She had it done at Cedars Hospital in Los Angeles by ALferdo Trento who is suppose to be the top Dog there. Since then she has had many test as to why she's tired all the time and tells me she would never have had it done if she knew how she would fill after. Has anyone had this problem? She has has many test to see why, but no answer. So if any of you know anything that might help shoot me a line. Thanks P/S. We been together just under 50 years and I hate the last one's to be like this. Help Wanted.
