Hi all - I'm a newbie here and I feel so grateful that there is a place to go to where everyone knows how it feels to have metastatic stage iv BC. (bones only) I'm on Ibrance and Faslosdex. I had (have) terrible shortness of breath. To make long story short, on top of the BC I have moderate to severe mitrol valve regurgitation. My ONC and Cardiologist are meeting to decide a course of action. My WBC's in the range of 1.2 - 1.7. Has anyone else been in this situation where a repair of a mitrol valve was done. I am worried about infections.
