Hi Mel,
I would also strongly suggest that you try combination therapy,it works wonders,specially L1 or Ferriprox is very good for removing iron from heart,one thing you have to do is test you WBC's every week while taking ferriprox,but i think it's better then having a chest line,and while you are going for transfusions every 4 weeks i think the duration is good,and combination therapy will hope fully work for you,ask your doc about that.
Good luck.
