chemo has possibly caused heart failure. not sure whats next

Yes, we are listening, and sharing your pain.

I went into surgery after three rounds of chemotherapy. The anaesthesiologist visited me the following day and said that I kept them on their toes the whole time because my heart kept going in and out of sinus rhythm. The chemo had caused me to have a minor heart block. It transpires that some chemotherapy is cardio toxic for some people. I was lucky the problem was minor and not life changing. Chemotherapy is poison, not just for tumours but for all cells in the body. The trick is to give just enough to have an effect on the tumour without killing the patient.

I hope your mother-in-law is comfortable and keeping cheerful and her family’s distress is not having too much of an effect on her well-being. She is probably not as distressed as you are. I always maintain it is worse for the loved ones than the victim. Covid has had a shrinking effect on everyone’s world, but it sounds as if she has caring family to keep her entertained and cheerful. Even if she can’t do the things she used to.

Thinking of you and wishing you and your MIL well.

Just like Brent's I was in surgery for 9 hours for the same reason, my surgeon had to call in a cardiologist to move the heart so the operation to remove the stomach could be completed.  I'm back to normal heart rhythm now but will require monitoring for sometime to come.
