dbug7857 I have both afib and bronchiectasis and Mac. I take Arikace for the Mac and xarelto and metoprolol for the afib. They seem to be conflicting conditions as far as medications and treatments go. The Arikace is an inhaled liposomal form of the antibiotic Amicacin and as such it is not systemic and does not interfere with the heart’s rhythm. It has helped to keep the Mac under control. I was told by a cardiac surgeon that I could not have an ablation until I got rid of the Mac because the mucus would interfere with the intubation and there would be no way to clear it. I still cough and bring up mucus when I lay flat for a while. If you have any more recent or different information please share your experience and what your docs have told you about treatments. Thanks, Candy
