Hello! When my mom had her mitral valve replaced in April ,(with a tissue-oink! she had a balloon pump inserted into her heart two days before surgery. Her cardio said she was in full regurgitation and needed it to help her heart pump. (after they had given her a TON of blood pressure meds and dropped it to 50/barely detectable-scary!!!!) I was just wondering if other people had to be on this too before their surgery-my mom waited too long to have hers done. Thankfully she is doing pretty well-thanks so everyone for this great site Debbie
